+
+This document tracks the curriculum's alignment with Accessibility Agents versions, capability evolution, and contribution pathways for facilitators and maintainers.
+
+## Version Alignment
+
+### Curriculum Version 2.0 (May 2026) - Accessibility Agents 5.0.0+

+
+### Previous Versions
+
+**Curriculum Version 1.0 (September 2025) - Accessibility Agents 4.x**
+- Chapter 16: GitHub Copilot introduction (basic agents, no cross-platform)
+- Appendices K-L: Copilot and 55 web/GitHub agents (web accessibility team only)
+- No document or developer tools support
+- No hooks or advanced skills
+
+---
+
+## Key Transitions: What Changed Between 4.x → 5.0.0
+
+### 1. Detection → Remediation Paradigm Shift
+
+**Before (4.x):** Agents reported issues; users fixed manually.
+**Now (5.0.0+):** Agents can auto-apply many fixes; users review and confirm.
+
+**Example:**
+```
+Version 4.x:
+User: @aria-specialist audit this component
+Agent: [Reports 3 ARIA errors]
+User: [Manually fixes issues in code]
+
+Version 5.0.0+:
+User: @web-issue-fixer audit-and-fix this component
+Agent: [Reports 3 ARIA errors]
+Agent: [Applies auto-fix for 2 errors; flags 1 for manual review]
+Agent: [Returns remediated code for approval]
+```
+
+### 2. Compliance Exports & VPAT Generation
+
+**Before (4.x):** No automated compliance reporting.
+**Now (5.0.0+):** Generate VPAT and compliance reports automatically.
+
+```
+User: @document-csv-reporter generate-vpat audit-findings.json
+Agent: [Exports findings mapped to WCAG 2.2 AA and Section 508]
+Agent: [Generates VPAT template with compliance assertions]
+Output: compliance-report.xlsx
+```
+
+### 3. Continuous Evaluation & Trending
+
+**Before (4.x):** One-off audits; no trend tracking.
+**Now (5.0.0+):** Track accessibility scores over time; identify improvement or regression.
+
+**Capability:**
+```
+Hook configuration:
+{
+  "name": "continuous-eval",
+  "event": "on-schedule",
+  "schedule": "0 2 * * 0",  // Weekly
+  "track": {
+    "metrics": ["page-score", "error-count"],
+    "baseline": "2026-01-01",
+    "frequency": "weekly"
+  }
+}
+
+Output: Trend report showing score changes week-over-week
+```
+
+### 4. Multi-Platform Parity
+
+**Before (4.x):** VS Code Copilot only.
+**Now (5.0.0+):** Same agents run on:
+- GitHub Copilot (VS Code)
+- Claude Code (CLI)
+- Gemini CLI
+- Claude Desktop
+- Codex CLI

+3. Appendix AB: Advanced Patterns (Skill-first workflows across platforms)
+4. Challenge 19.8: Run same agent on different platforms; compare outputs

+
+## Contribution Pathways for Facilitators
+
+### Adding a New Agent to Curriculum
+
+**When to propose a new agent:**
+- New accessibility domain not yet covered (e.g., internationalization, performance)
+- Platform-specific agent (macOS/Linux/mobile-specific)
+- New Agents 5.0+ feature (compliance export, hooks, etc.)
+
+**Proposal process:**
+
+1. **File an issue** in [git-going-with-github](https://github.com/Community-Access/git-going-with-github/issues) with:
+   - Agent name and purpose
+   - Which team it belongs to (Accessibility, GitHub Workflow, Developer Tools)
+   - Which chapter/appendix should reference it
+   - Example use case for learners
+
+2. **Create a challenge** if the agent is significant enough:
+   - Challenge 19.X: "[Agent Name] - [Task description]"
+   - Include success criteria (e.g., "Run agent, interpret findings, propose 3 fixes")
+   - Link to relevant agent documentation
+
+3. **Update appendices:**
+   - Appendix L: Add row to appropriate team table
+   - Appendix AB or AC: Add detailed section if advanced/specialized
+
+4. **Generate podcast episode** if content is substantial (> 20 min material)
+
+### Creating Custom Hooks for Classroom Use
+
+**Use case:** Enforce accessibility standards across a GitHub Classroom cohort.
+
+**Hook template:**
+
+```json
+{
+  "name": "classroom-accessibility-gate",
+  "event": "on-commit",
+  "pattern": "src/**/*.{jsx,tsx,html}",
+  "agent": "@web-accessibility-wizard",
+  "condition": "severity >= 'error'",
+  "action": "create-issue",
+  "labels": ["accessibility", "cohort-1", "blocking"],
+  "message": "Accessibility violations found. Use @web-issue-fixer to resolve before merge."
+}
+```
+
+**To add to curriculum:**
+1. Document the hook in admin guides (FACILITATOR_GUIDE.md, CLASSROOM_INTEGRATION_GUIDE.md)
+2. Create step-by-step setup instructions for facilitators
+3. Add troubleshooting section (e.g., "hook not triggering")
+
+### Updating Podcast Episodes
+
+**Files requiring regeneration with each curriculum version:**
+
+| Episode | File | Trigger | Regenerate When |
+|---------|------|---------|-----------------|
+| 17 | Chapter 19 | Agents expanded from 55→80, platforms added | Ch 19 expanded |
+| 39 | Appendix L | Agents/platforms/skills added | App L expanded |
+| 40 | Appendix K | MCP, 5-platform coverage, Copilot features | App K expanded |
+| NEW | Appendix AA | Agent installation guide | When App AA added |
+| NEW | Appendix AB | Advanced patterns, hooks, skills | When App AB added |
+| NEW | Appendix AC | Document and developer agents | When App AC added |
+
+**Podcast generation process:**
+1. Review chapter/appendix changes in git diff
+2. Extract key learning points (3-5 min main content)
+3. Record Alex + Jamie conversation (see admin/PODCASTS.md for style guide)
+4. Add full transcript below audio player
+5. Update RSS feed and release notes
+

+### Three Teams, 80 Agents, 5 Platforms
+
+```
+Accessibility Agents 5.0.0
+├── Team 1: Accessibility (40 agents)
+│   ├── Web (26): Specialists, wizards, coaches
+│   ├── Document (14): Word, Excel, PowerPoint, PDF, EPUB

+    ├── Claude Code (CLI)
+    ├── Gemini CLI
+    ├── Claude Desktop (MCP)
+    └── Codex CLI (TOML)

+
+### Core Skills (25+)
+
+**Categories:**
+- Web scanning & severity scoring (2)
+- Document scanning & compliance (2)
+- Markdown accessibility (3)
+- CI/CD integration (2)
+- Framework-specific patterns (3)

+- Agents use skills internally (not visible to learners by default)
+- Advanced users can invoke skills directly via slash commands
+- Facilitators can create custom skills for classroom use
+
+### MCP Server (30+ Tools)
+
+MCP (Model Context Protocol) provides standardized tool access across platforms.
+
+**Tool categories:**
+- Web scanning (8): page, pages, DOM, Lighthouse, Playwright, etc.
+- Document (10): Word, Excel, PowerPoint, PDF, EPUB scanning
+- Markdown (4): scanning, linting, validation
+- Compliance (5): severity scoring, WCAG mapping, VPAT generation
+- CI/CD (3+): GitHub Actions integration, artifact parsing

Inside that repo, an automation system called Aria guides you through a series of challenges delivered as GitHub Issues.

 **Alex:** Now bring the learner back to the room. Software - Required Before the Workshop has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** For a learner, the useful signals are concrete. Git - Download Git (Windows/Linux) or Xcode Command Line Tools (macOS). Visual Studio Code (free) - download here (GitHub Copilot is included automatically). A GitHub Copilot subscription or Free tier access (Copilot Free is available to all GitHub users).
+**Alex:** For a learner, the useful signals are concrete. Git - Download Git (Windows/Linux) or Xcode Command Line Tools (macOS). Visual Studio Code (free) - download here (GitHub Copilot is included automatically). VS Code version 1.113 or later (required for Accessibility Agents in Chapter 19). A GitHub Copilot subscription or Free tier access (Copilot Free is available to all GitHub users).
 
-**Jamie:** How should someone choose between those options?
+**Jamie:** What should they understand before typing anything?
 
-**Alex:** The reason this matters is simple: use whichever you are most comfortable with. The listener should be able to check this: All workshop exercises are designed to work with any of these screen readers.
+**Alex:** The reason this matters is simple: if you plan to use Accessibility Agents (Chapter 19), advanced accessibility features, or the optional Day 2 extension exercises, ensure you have the following minimum versions. The listener should be able to check this: If you don't have Node.js installed, that's fine - it's only needed if you use command-line accessibility tools (optional for Day 2 extension exercises).
 
-**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Screen Reader means Platform means Download. NVDA (NonVisual Desktop Access) means Download NVDA. JAWS (Job Access With Speech) means Paid (trial available) means Download JAWS.
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like code --version VS Code version; node --version Node.js (if installed); git --version Git version. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
 
-**Alex:** That matters because of the next idea. Do not treat Step 1 - Create Your GitHub Account as decoration. See also: Appendix D: Git Authentication covers SSH keys and personal access tokens in detail. That is not trivia. If you already have a GitHub account, skip to Step 2. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+**Jamie:** What decision is this helping them make?

+**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
 
-**Alex:** If the interface shifts, Create an account is still useful because GitHub presents a visual CAPTCHA puzzle to verify you are human. For someone navigating by keyboard or screen reader, this detail matters: Follow the on-screen prompts - typically clicking images that match a category, or checking a box.
+---
 
-**Alex:** Here is what that changes in practice. Type your email address and press Tab or activate Continue. Choose a password of at least 8 characters (15+ recommended). Press Tab or Continue. Your username appears on every issue, PR, and comment you make. Guidelines. Use lowercase letters, numbers, and hyphens only.
+**Jamie:** Okay, set the room for us. What are we walking into?
 
-**Alex:** Start here: Open your browser and navigate to the GitHub signup page. Then: The page loads with focus on the first field: "Enter your email address". Next: The next field is "Create a password". Last: The next field is "Enter a username". The sequence works because every action has a confirmation.

For someone navigating by keyboard or screen reader, this detail matters: If you already have a GitHub account, skip to Step 2.
 
 **Jamie:** What does the learner do first, second, and then after that?
 
-**Alex:** Walk it in order: The next question asks whether you want to receive product updates by email; Human verification step; Activate the Create account button; and GitHub sends a launch code (a short numeric code) to your email inbox. Keep it that plain: know where you are, make the move, check the result.
+**Alex:** Put Create an account into plain language. GitHub presents a visual CAPTCHA puzzle to verify you are human. The useful version is: Follow the on-screen prompts - typically clicking images that match a category, or checking a box.

Keep it that plain: know where you are, make the move, check the result.
+
+**Jamie:** Turn that into a path someone can follow.
 
-**Alex:** This is where the talk moves from concept to action. Put Verify your email address into plain language. GitHub also sends a separate email verification link after account creation. The useful version is: Check your inbox for an email from GitHub with subject "Please verify your email address" and activate the link inside it.
+**Alex:** Think of this as 4 checks: The next question asks whether you want to receive product updates by email; Human verification step; Activate the Create account button; and GitHub sends a launch code (a short numeric code) to your email inbox. Pause after each step and listen for the confirmation before moving on.
 
 **Jamie:** Now it sounds like a workflow instead of a wall of instructions.
 
 **Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
 
-**Jamie:** Where does the workshop stop being a tour and start becoming contribution?
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
 
-**Alex:** The teaching point here is not the label; it is the move. Two-factor authentication (2FA) adds a second verification step each time you sign in, protecting your account if your password is compromised. That is the difference between guessing and knowing: GitHub now requires 2FA for all accounts, so you may already have it enabled.

-**Jamie:** What is the ordered workflow?
-
-**Alex:** Quick steps to enable 2FA has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** That becomes easier when you listen for these cues. GitHub Mobile app (recommended for this workshop): Install the free GitHub Mobile app on your phone. Once linked to your account, GitHub sends a push notification to your phone each time you sign in. You simply tap Approve - no codes to type. The app is. Authenticator app: Microsoft Authenticator, Google Authenticator, Authy - generates time-based 6-digit codes. Security key / passkey (most secure): hardware security keys (YubiKey, etc.) or platform passkeys (biometric device credentials). SMS / text message (least preferred): can be used if other options are unavailable.
+**Alex:** Before the learner moves on. This part earns its place because two-factor authentication (2FA) adds a second verification step each time you sign in, protecting your account if your password is compromised. That gives the learner a foothold: GitHub now requires 2FA for all accounts, so you may already have it enabled. That is the difference between following directions and owning the workflow.
 
-**Alex:** The path is straightforward once it is named. Step one is open the GitHub security settings page while signed in. Step two is under Two-factor authentication, choose Enable and follow the prompts. Step three is choose one of the second-factor methods (recommended order). The point is not speed; the point is never losing your place.
+**Jamie:** Give me the sequence, because order matters here.
 
-**Jamie:** What is the pre-flight check here?
+**Alex:** Quick steps to enable 2FA has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Detailed setup notes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** If someone is taking notes, this is the short list. GitHub Mobile app (recommended for this workshop): Install the free GitHub Mobile app on your phone. Once linked to your account, GitHub sends a push notification to your phone each time you sign in. You simply tap Approve - no codes to type. The app is. Authenticator app: Microsoft Authenticator, Google Authenticator, Authy - generates time-based 6-digit codes. Security key / passkey (most secure): hardware security keys (YubiKey, etc.) or platform passkeys (biometric device credentials). SMS / text message (least preferred): can be used if other options are unavailable.
 
-**Alex:** If someone is taking notes, this is the short list. Authenticator app (recommended). Visual users: scan the QR code with your authenticator app and enter the 6-digit code shown. Screen reader users: choose the link labeled "enter this text code" or "can't scan the barcode?" to reveal the secret (a 32-character key). Use the authenticator app's manual/key-entry option to add the account. Security key / passkey. Follow the on-screen prompts to register a hardware key or platform passkey. These are highly recommended for long-term security and are supported by modern browsers and devices. SMS / text message.
+**Alex:** First, open the GitHub security settings page while signed in. Then, under Two-factor authentication, choose Enable and follow the prompts. After that, choose one of the second-factor methods (recommended order). Each step should leave a trace you can name.

+**Alex:** Now slow down for the part people usually miss. Detailed setup notes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part that makes the next action easier. After enabling 2FA, GitHub will display recovery (single-use) codes. Immediately copy, download, or securely store these codes (password manager or physically secure location). They are the only fallback if you lose your second-factor device. Consider registering more than one second-factor method (e.g., authenticator app + a hardware key) to avoid account lockout.

-**Jamie:** Turn that into a path someone can follow.
+**Jamie:** What do you want them to do when the plan breaks?
 
-**Alex:** This is the move inside Authenticating Git with GitHub: browser-based sign-in (OAuth): when you use Git inside VS Code or GitHub Desktop, you do not need to manage passwords, tokens, or SSH keys manually. That matters in practice: These tools use browser-based OAuth sign-in - the same "Sign in with GitHub" flow you use on any website.
+**Alex:** Recovery and backup has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Walk it in order: The first time you push or pull code, VS Code (or GitHub Desktop) opens your default web browser to a GitHub authorization page; Sign in to GitHub in the browser (including your 2FA step - a push notification if you use GitHub Mobile, or a code from your authenticator app); Approve the authorization request; and Switch back to VS Code. Your credentials are securely stored by your operating system's credential manager, so you will not be prompted again on this machine. That is the rhythm: orient, act, verify, continue.
+**Alex:** These are the pieces that turn the idea into a usable move. After enabling 2FA, GitHub will display recovery (single-use) codes. Immediately copy, download, or securely store these codes (password manager or physically secure location). They are the only fallback if you lose your second-factor device. Consider registering more than one second-factor method (e.g., authenticator app + a hardware key) to avoid account lockout.
 
 **Jamie:** That is the kind of detail that keeps a screen reader user oriented.
 
 **Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
 
-**Alex:** A solid Git habit is to know which branch you are on, what changed, and what confirmation you expect before you run the next command.
+**Jamie:** What is the ordered workflow?
 
-**Alex:** Here is the moment where the page starts to make sense. Anchor this part on Workshop policy. For this workshop, participants need a GitHub account with 2FA enabled. This is the part to say slowly: The browser-based sign-in described above handles all Git authentication automatically - no additional setup is required beyond having a working GitHub account. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.

-**Alex:** Learning Cards: Create Your GitHub Account has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Where is the promise of the workshop, underneath all the logistics?
 
-**Alex:** The useful version is not abstract; it sounds like this. During signup, press Tab to move between form fields; GitHub announces validation errors inline as you type. The CAPTCHA step may not have an audio fallback -- look for a button labeled "Audio" or "Try an audio challenge" before requesting help. After enabling 2FA, use Ctrl+A then Ctrl+C in the recovery codes text area to copy all codes at once into a password manager. GitHub signup fields have high-contrast focus rings; if you cannot see them, switch to your browser's High Contrast mode (Alt+Shift+H in Edge) before starting. Zoom to 200% on the verification puzzle -- the puzzle images scale but button text may overlap; resize the browser window wider if controls disappear. Recovery codes are displayed in small monospace text; use Ctrl+Plus to enlarge before copying them.

-**Alex:** The next point gives the learner a handle. Do not treat Step 2 - Configure GitHub Accessibility Settings as decoration. These settings make GitHub significantly more usable with a screen reader. That is not trivia. Do not skip this section - one setting in particular (hovercards) adds significant noise to every page if left on.

+**Jamie:** What would you say to someone who is already bracing for this to be too much?
+
+**Alex:** If the interface shifts, Step 2 - Configure GitHub Accessibility Settings is still useful because these settings make GitHub significantly more usable with a screen reader. For someone navigating by keyboard or screen reader, this detail matters: Do not skip this section - one setting in particular (hovercards) adds significant noise to every page if left on.
 
-**Alex:** If the interface shifts, Navigate to Accessibility Settings is still useful because the fastest path for everyone: navigate directly to GitHub Accessibility Settings while signed in. For someone navigating by keyboard or screen reader, this detail matters: If you prefer to navigate through the interface.
+**Jamie:** How would you walk the room through that step by step?
 
-**Alex:** Start here: Click your profile picture (avatar) in the top-right corner of any GitHub page. Then: A dropdown menu appears - click Settings. Next: On the Settings page, scroll the left sidebar and click Accessibility. Last: On any GitHub page, switch to Browse Mode if you are not already in it (NVDA+Space / JAWS virtual cursor should be on by default in browsers). Pause after each step and listen for the confirmation before moving on.
+**Alex:** Put Navigate to Accessibility Settings into plain language. The fastest path for everyone: navigate directly to GitHub Accessibility Settings while signed in.

 **Jamie:** Let's pause on 1. Disable Hovercards (highest priority). What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. Hovercards are the most disruptive default setting for screen reader users on GitHub. That is the difference between guessing and knowing: When enabled, every link announces its hover keyboard shortcut (H) as you navigate past it, dramatically slowing page reading.

 **Alex:** 3. Character Key Shortcuts has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The parts worth keeping in working memory are these. If your screen reader uses letters for navigation in Browse Mode (NVDA, JAWS), GitHub's single-key shortcuts are suppressed when Browse Mode is active, so conflicts are rare in practice. If you notice unexpected behavior, return here and turn them off.

If you notice unexpected behavior, return here and turn them off.
 
-**Alex:** First, find "Character key shortcuts". Then, single-key shortcuts (H for next heading, I for next issue, etc.) speed up navigation but can conflict with screen reader quick-navigation keys. After that, leave at the default unless you have a reason to change it. That is the rhythm: orient, act, verify, continue.

+**Alex:** This is the move inside 4. Set Your Theme (Appearance Settings): theme is on a separate page: GitHub Appearance Settings.
 
-**Alex:** On the ground, that means a few things. Light default - standard white background. Dark default - dark background, easier on some eyes. High contrast light - maximum contrast, recommended for low vision. High contrast dark - maximum contrast on dark background. Colorblind variants - Protanopia, Deuteranopia, Tritanopia.

-**Jamie:** Okay, set the room for us. What are we walking into?
+**Jamie:** Where do you want a learner to place their attention here?
+
+**Alex:** The reason this matters is simple: your GitHub profile is your public identity in the open source community. The listener should be able to check this: Setting it up properly helps maintainers know who you are.
 
-**Alex:** The reason this matters is simple: maintainers are the people who manage a repository -- they review contributions, respond to issues, merge pull requests, and keep the project running. The listener should be able to check this: When you open an issue or submit a pull request, a maintainer is the person who will see it and respond.
+**Alex:** Another way to ground it. Do not treat Who are maintainers? as decoration. Maintainers are the people who manage a repository -- they review contributions, respond to issues, merge pull requests, and keep the project running. That is not trivia. When you open an issue or submit a pull request, a maintainer is the person who will see it and respond. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.

Bio - a short description (e.g., "Accessibility advocate and open source contributor"). Location - optional but builds trust in the community. Website or social links - optional.

New Files Changed Experience - adds proper landmark structure, an accessible file tree, and better keyboard navigation to the Files Changed tab in Pull Requests. GitHub Command Palette - a keyboard-first command launcher (Ctrl+K on Windows, Cmd+K on macOS) that lets you navigate to any repository, issue, PR, file, or page by typing its name.

-**Alex:** The path is straightforward once it is named. Step one is sign in to GitHub and go to any page. Step two is click your profile picture (avatar) in the top-right corner. Step three is in the dropdown menu, click Feature preview. Step four is a panel opens on the right side of the screen listing available features. That small check between steps is what makes the workflow reliable.

If you open Feature Preview and neither "New Issues Experience" nor "New Files Changed Experience" appears in the list at all - that is good news. Put another way, it means both features have graduated to the standard GitHub interface and are active automatically for every user.

+**Alex:** This is where the talk moves from concept to action. Learning Cards: Install Git and Visual Studio Code has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. After installing VS Code, press Shift+Alt+F1 immediately to enable Screen Reader Optimized mode; without it the editor area is not linearized for your screen reader. Press Ctrl+Shift+P to open the Command Palette; it behaves like an autocomplete list -- type a few letters and press Down Arrow to browse matches. The VS Code terminal ( Ctrl+ ) is a standard text area; press Up Arrow` to review previous command output line by line. In VS Code, press Ctrl+Plus or Ctrl+Minus to zoom the entire interface; the zoom level persists across restarts. Open Settings (Ctrl+,), search "editor.fontSize" and increase it to 18-24 for comfortable code reading alongside your browser zoom. Choose a high-contrast theme: press Ctrl+K Ctrl+T, then select "High Contrast" or "High Contrast Light" from the list.
 
-**Alex:** Keep the teaching thread moving. This part earns its place because now that Git is installed, tell it who you are. That gives the learner a foothold: Git embeds your name and email in every commit you make, and this affects how your contributions appear in project history.

+**Jamie:** Let's pause on Step 7 - Configure Git Identity. What should a learner take away from it?
+
+**Alex:** Step 7 - Configure Git Identity: Now that Git is installed, tell it who you are. The next useful detail is concrete: Git embeds your name and email in every commit you make, and this affects how your contributions appear in project history.
+
 **Jamie:** Let's pause on Configure in VS Code. What should a learner take away from it?
 
 **Alex:** Configure in VS Code has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. Menu: Terminal → New Terminal. Keyboard: Ctrl+ (Windows) or Cmd+ `` (Mac).
 
-**Alex:** First, open Visual Studio Code. Then, open the integrated terminal. After that, type the following commands, replacing with your information. That is the rhythm: orient, act, verify, continue.
+**Alex:** Start here: Open Visual Studio Code. Then: Open the integrated terminal. Next: Type the following commands, replacing with your information. That small check between steps is what makes the workflow reliable.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git config --global user.name "Your Name"; git config --global user.email "your-email@example.com". Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. The terminal in VS Code is accessible with all major screen readers. Put another way, press Ctrl+ to move focus to the terminal, type your commands, and press Enter`. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Jamie:** Let's pause on What to use. What should a learner take away from it?
+
+**Alex:** This is the move inside What to use: the terminal in VS Code is accessible with all major screen readers. That matters in practice: Press Ctrl+ to move focus to the terminal, type your commands, and press Enter`.
 
 **Alex:** Here is the part to remember. user.name: Your real name or the name you want shown on commits (e.g., "Jane Smith"). user.email: The email address associated with your GitHub account (must match exactly).
 
-**Jamie:** Let's pause on Why This Matters. What should a learner take away from it?
+---
 
-**Alex:** This is the move inside Why This Matters: if Git isn't configured, it will either.
+**Alex:** Keep the teaching thread moving. Anchor this part on Why This Matters. If Git isn't configured, it will either.
 
 **Alex:** Here is the part to remember. Use a default name like "Unknown" (looks unprofessional in project history). Refuse to create commits with an error message.
 
----
-
-**Jamie:** What should happen before anyone copies and runs it?
+**Jamie:** How do you keep commands from becoming magic words?
 
-**Alex:** Anchor this part on Verify Your Configuration. Run this command to see your current settings.
+**Alex:** The reason this matters is simple: run this command to see your current settings.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git config --global --list. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Jamie:** Let's pause on Using the Correct Email. What should a learner take away from it?
-
-**Alex:** The reason this matters is simple: use the same email you registered with GitHub. The listener should be able to check this: If you're concerned about privacy, GitHub offers a no-reply email you can use: username@users.noreply.github.com - find it in Settings → Emails.
-
-**Alex:** Keep the teaching thread moving. Do not treat Step 8 - Install VS Code Extensions as decoration. This workshop uses two VS Code extensions. That is not trivia. GitHub Copilot is built into VS Code automatically. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.

-**Jamie:** Let's pause on GitHub Copilot (Built In). What should a learner take away from it?
+**Jamie:** There are a lot of tools in play. How do we keep that from feeling like a contest?
+
+**Alex:** If the interface shifts, Step 8 - Install VS Code Extensions is still useful because this workshop uses two VS Code extensions. For someone navigating by keyboard or screen reader, this detail matters: GitHub Copilot is built into VS Code automatically.
 
-**Alex:** If the interface shifts, GitHub Copilot (Built In) is still useful because GitHub Copilot is automatically included with Visual Studio Code. For someone navigating by keyboard or screen reader, this detail matters: There is no extension to install separately.
+**Alex:** Keep the teaching thread moving. Put GitHub Copilot (Built In) into plain language. GitHub Copilot is automatically included with Visual Studio Code. The useful version is: There is no extension to install separately.
 
 **Jamie:** Let's pause on Activate Copilot. What should a learner take away from it?
 
-**Alex:** Put Activate Copilot into plain language. You do not need to use the Command Palette to sign in. The useful version is: If you are logged into GitHub in your browser, VS Code handles authentication automatically when you first interact with the agent.
+**Alex:** The teaching point here is not the label; it is the move. You do not need to use the Command Palette to sign in. That is the difference between guessing and knowing: If you are logged into GitHub in your browser, VS Code handles authentication automatically when you first interact with the agent.
 
 **Alex:** Here is the part to remember. Your screen reader should announce the chat input field.
 
-**Alex:** Walk it in order: Make sure Screen Reader Mode is enabled (see above); Make sure you are signed into GitHub in your web browser; Press Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs, to open the Chat view; and VS Code will automatically sign you into GitHub Copilot using your browser session - no manual sign-in command is needed. If one step does not match what you hear, stop there and re-orient.
+**Alex:** Think of this as 4 checks: Make sure Screen Reader Mode is enabled (see above); Make sure you are signed into GitHub in your web browser; Press Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs, to open the Chat view; and VS Code will automatically sign you into GitHub Copilot using your browser session - no manual sign-in command is needed. That is the rhythm: orient, act, verify, continue.
 
 **Jamie:** Before we leave Activate Copilot, what is the practical point?
 
-**Alex:** Think of this as 2 checks: A response will appear in the chat history above the input field; and Navigate up with Shift+Tab or Up Arrow to read the response. That is the rhythm: orient, act, verify, continue.
-
-**Jamie:** Let's pause on Extension 2 - GitHub Pull Requests. What should a learner take away from it?
-
-**Alex:** The teaching point here is not the label; it is the move. This extension lets you review and manage pull requests without leaving VS Code. That is the difference between guessing and knowing: It is used in the code review chapters.
+**Alex:** The path is straightforward once it is named. Step one is a response will appear in the chat history above the input field. Step two is navigate up with Shift+Tab or Up Arrow to read the response. That small check between steps is what makes the workflow reliable.
 
 ---
 
+**Alex:** Keep the teaching thread moving. This part earns its place because this extension lets you review and manage pull requests without leaving VS Code. That gives the learner a foothold: it is used in the code review chapters. That is the difference between following directions and owning the workflow.
+
 **Jamie:** Let's pause on Install. What should a learner take away from it?
 
-**Alex:** This part earns its place because extension imposter warning: The VS Code Marketplace contains third-party extensions with similar names. That gives the learner a foothold: always verify the publisher before installing. That is the difference between following directions and owning the workflow.
+**Alex:** Install: Extension imposter warning: The VS Code Marketplace contains third-party extensions with similar names. The next useful detail is concrete: Always verify the publisher before installing.
 
 **Alex:** Here is the part to remember. This extension was formerly named "GitHub Pull Requests and Issues" - either name is correct.
 
-**Alex:** The path is straightforward once it is named. Step one is press Ctrl+Shift+X to open the Extensions panel. Step two is press Tab to move into the results list. Step three is arrow down to find "GitHub Pull Requests" with publisher "GitHub". Step four is press Enter to open the details page. That small check between steps is what makes the workflow reliable.
+**Alex:** First, press Ctrl+Shift+X to open the Extensions panel. Then, press Tab to move into the results list. After that, arrow down to find "GitHub Pull Requests" with publisher "GitHub". Finally, press Enter to open the details page. The sequence works because every action has a confirmation.
 
 **Jamie:** Before we leave Install, what is the practical point?
 
-**Alex:** First, press Tab to the Install button and press Enter or Space. Then, VS Code will announce when installation is complete. The sequence works because every action has a confirmation.
+**Alex:** Start here: Press Tab to the Install button and press Enter or Space. Then: VS Code will announce when installation is complete. Keep it that plain: know where you are, make the move, check the result.
 
 **Jamie:** Let's pause on Verify it is working. What should a learner take away from it?
 
-**Alex:** Verify it is working: The Pull Requests panel is a tree view. The next useful detail is concrete: Navigate it with Up and Down Arrow.
+**Alex:** Here is the learner-facing version. The Pull Requests panel is a tree view. Put another way, navigate it with Up and Down Arrow.
 
 **Alex:** Here is the part to remember. If you are already signed in from the earlier step, this command may not appear - that means you are already authenticated. The Pull Requests panel should open in the sidebar. If your repository has open pull requests, they will appear here.
 
-**Alex:** First, press Ctrl+Shift+P and type: GitHub Pull Requests: Sign in. Then, to confirm the extension loaded: press Ctrl+Shift+P, type GitHub Pull Requests: Focus on Pull Requests View. The sequence works because every action has a confirmation.
+**Alex:** Start here: Press Ctrl+Shift+P and type: GitHub Pull Requests: Sign in. Then: To confirm the extension loaded: press Ctrl+Shift+P, type GitHub Pull Requests: Focus on Pull Requests View. Keep it that plain: know where you are, make the move, check the result.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Copilot Free is available to all GitHub users at no cost. Put another way, for this workshop, Free tier is sufficient.
+---
 
-**Alex:** Here is the part to remember. Limited inline code completions per month. Limited Copilot Chat messages per month.
+**Jamie:** Let's pause on Copilot Free tier. What should a learner take away from it?
 
----
+**Alex:** This is the move inside Copilot Free tier: Copilot Free is available to all GitHub users at no cost. That matters in practice: For this workshop, Free tier is sufficient.

+**Alex:** Keep the teaching thread moving. Learning Cards: Install VS Code Extensions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. In the Extensions panel (Ctrl+Shift+X), type your search, press Tab to enter the results list, then Down Arrow through results; each announces the extension name and publisher. Verify the publisher is "GitHub" before installing; after arrowing to a result, press Tab once to hear the publisher name announced. To confirm Copilot is active, press Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs; your screen reader should announce the chat input field within two seconds. Extension search results show the publisher name in smaller grey text beneath the extension name; zoom to 150%+ to read it clearly. The Install button is blue and appears on the right side of each extension card; after installation it changes to a gear icon for settings. The Copilot icon in the Status Bar (bottom right, a small two-sparkle icon) turns solid when Copilot is authenticated and active.
 
-**Jamie:** How do you keep commands from becoming magic words?
+**Jamie:** What is the safe way to learn from that example?
 
-**Alex:** Anchor this part on Tool Cards: Verify Your Setup. github.com (browser): Sign in at github.com and verify your profile, accessibility settings, and that you can navigate with keyboard shortcuts (G I for Issues, G P for Pull Requests). This is the part to say slowly: VS Code Desktop: Open VS Code and confirm: Screen Reader Mode is on (Shift+Alt+F1), Git is detected (run git --version in the terminal), and the GitHub Pull Requests extension is installed. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** The reason this matters is simple: github.com (browser): Sign in at github.com and verify your profile, accessibility settings, and that you can navigate with keyboard shortcuts (G I for Issues, G P for Pull Requests). The listener should be able to check this: VS Code Desktop: Open VS Code and confirm: Screen Reader Mode is on (Shift+Alt+F1), Git is detected (run git --version in the terminal), and the GitHub Pull Requests extension is installed.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git --version; git config user.name; git config user.email; gh auth status if GitHub CLI is installed. Pre-Workshop Checklist; GITHUB ACCOUNT; [ ] GitHub account created and email verified; [ ] Two-factor authentication enabled; [ ] Profile name, bio set; GITHUB SETTINGS; [ ] Accessibility settings page visited; [ ] Hovercards / link previews turned OFF; [ ]. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Jamie:** If setup starts to feel like a barrier, how should a learner think about it?
-
-**Alex:** The reason this matters is simple: you do not need to claim a workshop repository before Day 1 -- that is the very first hands-on step we do together in Block 0. The listener should be able to check this: When the workshop opens, the facilitator will paste a GitHub Classroom assignment link in the chat.
-
 ---
 
-**Alex:** Keep the teaching thread moving. Do not treat Other GitHub Access Methods (Reference Only) as decoration. This workshop focuses entirely on GitHub.com in the browser and VS Code. That is not trivia. However, you should be aware that other ways to work with GitHub exist.
+**Alex:** Keep the teaching thread moving. Do not treat What Happens at the Start of Day 1 as decoration.

When the workshop opens, the facilitator will paste a GitHub Classroom assignment link in the chat.
 
-**Jamie:** What should someone listen for when a lesson offers more than one tool path?
+**Jamie:** Let's pause on Other GitHub Access Methods (Reference Only). What should a learner take away from it?
 
-**Alex:** If the interface shifts, GitHub Desktop is still useful because a graphical desktop application for managing repositories, branches, and commits without using the command line.
+**Alex:** If the interface shifts, Other GitHub Access Methods (Reference Only) is still useful because this workshop focuses entirely on GitHub.com in the browser and VS Code. For someone navigating by keyboard or screen reader, this detail matters: However, you should be aware that other ways to work with GitHub exist.
+
+**Alex:** Keep the teaching thread moving. Put GitHub Desktop into plain language. A graphical desktop application for managing repositories, branches, and commits without using the command line. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
 **Alex:** Here is the part to remember. Download: desktop.github.com. Provides a visual interface for cloning, committing, pushing, and creating PRs. Has some screen reader support, though the web interface is generally more accessible. A good option for those who prefer a visual GUI over the command line.
 
-**Jamie:** What is the safe way to learn from that example?
+---
+
+**Jamie:** What should happen before anyone copies and runs it?
 
-**Alex:** Put GitHub CLI (gh) into plain language. A command-line tool that lets you perform nearly any GitHub action directly from your terminal. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** The teaching point here is not the label; it is the move. A command-line tool that lets you perform nearly any GitHub action directly from your terminal.
 
 **Alex:** Here is the part to remember. Download: cli.github.com. Excellent for automation and scripting. Very accessible - terminal/command-line interfaces work well with screen readers. Full documentation: cli.github.com/manual.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Examples (reference only - not covered in this workshop); gh repo clone owner/repo; gh issue create; gh pr create; gh pr review; gh pr merge. Read the command, understand what it changes, then run it only when the repository state matches the lesson.

-**Jamie:** What should they understand before typing anything?
+**Jamie:** Let's pause on GitHub Copilot CLI (gh copilot). What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. An extension to the GitHub CLI that brings Copilot assistance to the terminal. That is the difference between guessing and knowing: You can ask it to explain or suggest shell commands in plain English.
+**Alex:** This part earns its place because an extension to the GitHub CLI that brings Copilot assistance to the terminal. That gives the learner a foothold: you can ask it to explain or suggest shell commands in plain English.

 **Jamie:** Let's pause on Getting Help Before the Event. What should a learner take away from it?
 
-**Alex:** Getting Help Before the Event: If you cannot complete any step in this guide before the workshop. The next useful detail is concrete: Every setup issue we can solve before Day 1 means more time for learning on the day.
+**Alex:** Here is the learner-facing version. If you cannot complete any step in this guide before the workshop.

-**Alex:** First, file a setup support issue - Community-Access/support/issues - we will help you get set up. Then, join Support Hub Discussions - Community-Access/support/discussions - read pinned Start Here guidance and ask follow-up questions. After that, join the GitHub Accessibility Discussions - GitHub Community Accessibility Discussions - the community is helpful and welcoming.

 **Alex:** The next layer is this. Here is the learner-facing version. Access note, verified May 12, 2026: GitHub Copilot Free is available to individual developers with monthly limits, and verified students may have access to the GitHub Copilot Student plan. Put another way, organization or enterprise access depends on your administrator's policy. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.

 **Alex:** Here is the part to remember. Agent mode's terminal command approval dialogs are announced differently by NVDA ("dialog") vs JAWS ("message box") vs VoiceOver ("alert") -- learn your screen reader's announcement so you recognize approval prompts instantly. Listen for the confirmation prompt before any terminal command executes -- pressing Enter without reading the command is the single highest-risk action in Agent mode. Use Accessible View (Alt+F2) to review the multi-step plan Agent mode proposes before approving; the plan is often too long for live region announcements to capture fully. Agent mode's progress appears in the Chat panel -- if your zoom level pushes the panel narrow, widen it or pop it out so multi-step status lines do not truncate. Terminal command approval buttons use the same accent color as other VS Code buttons; consider a high-contrast theme so approval prompts stand out from surrounding chat text. Watch the file tabs along the top -- Agent mode opens and edits files automatically, and new tabs appearing is your visual cue that changes are happening.
 
-**Alex:** Keep the teaching thread moving. Do not treat 7. Next Edit Suggestions as decoration. Next Edit Suggestions (NES) is a feature where Copilot watches what you're editing and predicts where you'll need to make your next change -- then offers to make it for you. That is not trivia. Unlike regular inline suggestions that complete what you're currently typing, NES looks ahead to related edits elsewhere in the file.
+**Alex:** Keep the teaching thread moving. Do not treat 6A. VS Code 1.120 Agents Window as decoration. VS Code 1.120 adds the Agents window to Stable as a Preview feature. That is not trivia. Agent mode is a way for Copilot to behave inside a session.
 
-**Jamie:** Let's pause on Turning on Next Edit Suggestions. What should a learner take away from it?
+**Jamie:** Let's pause on Open the Agents Window. What should a learner take away from it?
 
-**Alex:** Turning on Next Edit Suggestions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** If the interface shifts, Open the Agents Window is still useful because the following table shows when to stay in the editor and when to use the Agents window.
+
+**Alex:** Start here: Open the Command Palette with Ctrl+Shift+P. Then: Run Chat: Open Agents Window. Next: Sign in to GitHub if prompted. Last: Select New or press Ctrl+N. Pause after each step and listen for the confirmation before moving on.
+
+**Jamie:** Before we leave Open the Agents Window, what is the practical point?
+
+**Alex:** Walk it in order: Choose a workspace folder or GitHub repository; Choose the agent type, isolation mode, custom agent, and model if those controls are available to your account; and Write a focused task and review the Changes panel before applying, committing, merging, or checking out the result. The point is not speed; the point is never losing your place.
+
+---
+
+**Alex:** Keep the teaching thread moving. Safety Notes for Workshop Learners has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Treat the Agents window as an advanced workflow surface. It helps you coordinate work, but it does not remove your responsibility to review changes. Prefer worktree isolation for Copilot CLI sessions while learning. It keeps agent edits separate from your active workspace. Use the Files panel sync button before starting a session when your branch may be behind upstream. Read terminal command risk badges if enabled, but still inspect the full command before approving. Run project validation tasks from the Agents window before accepting a completed session. If a session changes more files than expected, stop and review before continuing.
+
+**Jamie:** Let's pause on Accessibility Notes. What should a learner take away from it?
 
-**Alex:** Start here: Open Settings: Ctrl+, (Mac: Cmd+,). Then: Search for nextEditSuggestions. Next: Enable "GitHub Copilot: Next Edit Suggestions". Pause after each step and listen for the confirmation before moving on.
+**Alex:** The teaching point here is not the label; it is the move. Screen reader users: Open the Agents window through the Command Palette. That is the difference between guessing and knowing: Use Alt+F1 for context-specific Accessibility Help, F6 and Shift+F6 to move between workbench parts, and Alt+F2 for Accessible View when chat responses, terminal output, or diffs are too dense to follow live.
+
+**Alex:** Keep the teaching thread moving. This part earns its place because next Edit Suggestions (NES) is a feature where Copilot watches what you're editing and predicts where you'll need to make your next change -- then offers to make it for you. That gives the learner a foothold: unlike regular inline suggestions that complete what you're currently typing, NES looks ahead to related edits elsewhere in the file.

-**Alex:** Keep the teaching thread moving. Put How it works in practice into plain language. NES is announced as an inline suggestion at the predicted location. The useful version is: With screen reader optimized mode on (Shift+Alt+F1), VS Code announces when a next edit suggestion is available. The interface gets easier when it becomes a set of named places instead of a wall of controls.

+**Alex:** First, open Settings: Ctrl+, (Mac: Cmd+,). Then, search for nextEditSuggestions. After that, enable "GitHub Copilot: Next Edit Suggestions". That is the rhythm: orient, act, verify, continue.

A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
 **Alex:** Here is the part to remember. After making an edit, a tab stop indicator (an arrow → symbol) appears at the location of the predicted next edit. Press Tab to jump there and accept the suggestion. Press Escape to dismiss it and continue editing normally. The indicator is subtle -- if you don't see it, your next keystroke will proceed as normal.
 
 **Jamie:** Let's pause on 8. Copilot on GitHub.com. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. You don't need VS Code to use Copilot. That is the difference between guessing and knowing: GitHub.com has Copilot built directly into the website -- useful for quick questions, reviewing code in the browser, drafting PR descriptions, and more.
+**Alex:** This is the move inside 8. Copilot on GitHub.com: you don't need VS Code to use Copilot. That matters in practice: GitHub.com has Copilot built directly into the website -- useful for quick questions, reviewing code in the browser, drafting PR descriptions, and more.
 
-**Jamie:** Let's pause on Opening Copilot Chat on GitHub.com. What should a learner take away from it?
+---
 
-**Alex:** This part earns its place because Copilot on GitHub.com has context about your repositories, issues, PRs, and code - you can reference them directly.
+**Jamie:** Let's pause on Opening Copilot Chat on GitHub.com. What should a learner take away from it?
 
-**Alex:** The path is straightforward once it is named. Step one is go to github.com -- you must be signed in. Step two is look for the Copilot icon (a circle with dot pattern) in the top navigation bar. Step three is click it (or press? then select Copilot from the command palette) to open the chat panel. Step four is type your question and press Enter. If one step does not match what you hear, stop there and re-orient.

Keep it that plain: know where you are, make the move, check the result.
 
 **Jamie:** Let's pause on Copilot for Pull Request Summaries. What should a learner take away from it?
 
-**Alex:** Copilot for Pull Request Summaries: When you open a pull request on GitHub.com, Copilot can generate a description for you automatically. The next useful detail is concrete: Copilot-generated PR descriptions are usually a solid first draft.
+**Alex:** The reason this matters is simple: when you open a pull request on GitHub.com, Copilot can generate a description for you automatically. The listener should be able to check this: Copilot-generated PR descriptions are usually a solid first draft.
 
-**Alex:** First, start creating a new pull request: go to your branch and select "Compare & pull request". Then, in the PR form, look for the Copilot icon next to the description field. After that, click it -- Copilot reads your commits and diff and writes a draft description. Finally, review and edit the draft -- it typically includes what changed and why. That is the rhythm: orient, act, verify, continue.

-**Alex:** Start here: Submit the PR. That small check between steps is what makes the workflow reliable.
+**Alex:** First, submit the PR. The point is not speed; the point is never losing your place.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Maintainers can use Copilot to review pull requests on GitHub.com. Put another way, as a contributor, you may see Copilot-authored review comments on your PR - they look like regular review comments but are labelled "Copilot". A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.

You hear the move, try the move, and then check what changed.
 
 **Alex:** Here is the part to remember. Copilot review comments work just like human review comments -- respond, resolve, or address them. They flag things like potential bugs, style inconsistencies, or missing edge cases. You don't need to accept every suggestion -- use your judgment.

 **Jamie:** Let's pause on Learning Cards: Copilot on GitHub.com. What should a learner take away from it?
 
 **Alex:** Learning Cards: Copilot on GitHub.com has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. The Copilot chat icon on GitHub.com is in the site header -- navigate by landmark (d in NVDA/JAWS browse mode) to reach the banner, then find the button labeled "Open GitHub Copilot Chat". PR description generation uses a sparkle button ("Copilot actions") next to the description field -- Tab through the PR form controls to find it; it is not inside the markdown toolbar. Browser-based Copilot Chat responses are standard page content, not a VS Code panel -- your normal web reading commands (arrows, headings, links) work without any special mode. The Copilot icon in the GitHub.com header is small (16px) -- zoom to at least 200% or use browser find (Ctrl+F and type "Copilot") to locate the chat entry point faster. PR description suggestions appear inline in the description textarea; the sparkle button sits to the right of the formatting toolbar and may scroll off-screen at high zoom levels. GitHub.com Copilot Chat opens as a side panel that overlaps page content on narrow viewports -- resize the panel or collapse the file tree to reclaim space.

 **Alex:** Keep the teaching thread moving. Learning Cards: Effective Prompting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. Include "assume the reader uses a screen reader" in your prompts to get responses with keyboard shortcuts and non-visual descriptions by default. Ask Copilot to "use headings and bullet points" so the response is structured and easy to navigate with Alt+F2 (Accessible View). Iterate by saying "make it shorter" or "add more detail about NVDA" -- Copilot retains conversation context so you do not need to repeat the original request. Ask Copilot to "include a table" when requesting reference information -- tables are often easier to scan than dense paragraphs at high zoom. Use the "Draft from Outline" pattern: give Copilot your section headings and let it fill in the content, then review the structure before the details. If a response is too long to review comfortably, ask "summarize in 5 bullet points" for a manageable overview.

 **Alex:** Here is the part to remember. Build the Alt+F2 -- read -- Ctrl+/ muscle memory: press Alt+F2 to open Accessible View, read the response at your own pace with arrow keys, then press Ctrl+/ to insert the code suggestion into your file. Accessible View converts Copilot's streaming markdown into a plain text buffer -- headings, lists, and code blocks are all there, but read as flat text without formatting announcements, which is often easier to parse. If a Copilot response contains multiple code blocks, each block starts on its own line in Accessible View -- use your search command (Ctrl+F in the view) to jump between code blocks quickly. Accessible View opens as a separate editor pane that inherits your font size and theme -- if Copilot Chat text is too small in the sidebar, Alt+F2 gives you the same content at your preferred zoom. The Accessible View pane can be resized like any editor pane; drag the border or use the keyboard layout commands to give it more horizontal space for long code lines. Use Ctrl+/ from Accessible View to insert code at your cursor position without needing to copy-paste manually, reducing the chance of losing your place in the file.

 **Alex:** Here is the part to remember. After accepting a Copilot suggestion, run Ctrl+Shift+M to open the Problems panel -- if new errors appear, Copilot may have introduced invalid syntax or broken links. Use F8 to jump to the next error in the file and hear it announced; compare it against what Copilot changed to decide if the suggestion caused it. When Copilot generates Markdown, check heading levels with Ctrl+Shift+O (symbol outline) to verify the hierarchy was not broken. After accepting a suggestion, look for red squiggles (errors) or yellow squiggles (warnings) in the editor -- these appear near lines Copilot modified. Use Markdown Preview (Ctrl+Shift+V) to visually verify that Copilot-generated content renders correctly, especially tables and links. Zoom in on the Problems panel (Ctrl+Shift+M) to read error details that reference specific line numbers.

Then, ask a question - Type: What does the CONTRIBUTING.md file in this repository say about how to submit a pull request? Press Enter. After that, read the response - Press Ctrl+Shift+A to open the Accessible View if your screen reader doesn't read the response automatically. The response appears as plain text you can arrow through. Finally, try a follow-up - Type: Summarize that in 3 bullet points and press Enter. Copilot remembers the context from your first question. Pause after each step and listen for the confirmation before moving on.
+
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. VS Code 1.120 (May 2026) introduced several new Copilot features that accelerate common coding tasks without requiring explicit chat prompts. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Jamie:** Let's pause on Smart Actions. What should a learner take away from it?
+
+**Alex:** This is the move inside Smart Actions: smart Actions are AI-powered suggestions for common tasks like generating commit messages, renaming symbols, fixing errors, and searching for related code semantically. That matters in practice: They appear when you click the lightbulb icon (Ctrl+.) or interact with errors.

+
+**Alex:** Keep the teaching thread moving. Anchor this part on Browser Agent (Experimental). The Browser Agent (experimental) lets your Copilot agent test and validate web applications directly. This is the part to say slowly: It can open your app in the integrated browser, verify features, check layouts, and take screenshots.

Copilot Free is available with monthly usage limits suitable for learning and light use. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.

-**Alex:** Before the learner moves on. This part earns its place because GitHub Copilot supports multiple ways to provide custom instructions. That gives the learner a foothold: they differ by scope, priority, trigger mechanism, and which tools recognize them. That is the difference between following directions and owning the workflow.
+**Alex:** Before the learner moves on. This part earns its place because VS Code 1.120 introduces the Agents window (Preview, now Stable) for agent-first workflows. That is the difference between following directions and owning the workflow.
 
-**Jamie:** What would you say to someone who is already bracing for this to be too much?
+**Alex:** That becomes easier when you listen for these cues. Orchestrate tasks across multiple projects and workspaces. Track, review, and manage agent sessions (Copilot CLI, Copilot Cloud, Claude). Access a Customizations panel for agent personas, skills, hooks, MCP servers, and plugins. Use an integrated browser and terminal for validating agent changes. Start sessions on remote machines (SSH, dev tunnel). Create sub-sessions for parallel tasks in the same workspace.
 
-**Alex:** 4A. Always-On Instructions -.github/copilot-instructions.md: What it is: The primary VS Code Copilot instruction file. The next useful detail is concrete: Content is automatically included in every chat request and inline suggestion context - you never need to invoke it.
+**Jamie:** Give me the sequence, because order matters here.
+
+**Alex:** How to Open the Agents Window has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** First, select Open in Agents from the VS Code title bar. Then, open the Command Palette and run Chat: Open Agents Window. After that, run code --agents from a terminal. Each step should leave a trace you can name.
 
 **Jamie:** How would you walk the room through that step by step?

+
+**Jamie:** What does the learner do first, second, and then after that?
+
+**Alex:** Walk it in order: Prefer worktree isolation for Git projects (keeps agent edits separate until review); Use Files panel sync before agent starts to pull upstream changes; Type a clear, single task; and Review all changes in the Changes panel before accepting. That is the rhythm: orient, act, verify, continue.

-**Jamie:** How should a learner choose a tool without feeling judged by the choice?
+**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
+
+**Alex:** Accessibility and Inclusion has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** This is the move inside 4B. Always-On Instructions - AGENTS.md (Multi-Tool / Monorepo): what it is: An open standard instruction file recognized by multiple AI tools - GitHub Copilot, Claude Code, Gemini CLI, and others. That matters in practice: Use this instead of copilot-instructions.md when you want one instruction file that works across all AI coding assistants.
+**Alex:** These are the pieces that turn the idea into a usable move. Accessible View: Press Alt+F2 for screen reader-friendly suggestion review and insertion. Keyboard navigation: All panels and controls are keyboard accessible. Screen reader/low vision/sighted workflows: See learning cards below for detailed guidance. Markdown diff preview: Use for documentation changes; supports smart selection and HTML id validation.
 
 **Jamie:** That is the kind of detail that keeps a screen reader user oriented.
 
 **Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
 
-**Alex:** Here is the moment where the page starts to make sense. Anchor this part on 4C. Always-On Instructions - CLAUDE.md (Cross-Tool Compatibility). What it is: Instructions file originally from Claude Code that VS Code Copilot also recognizes. This is the part to say slowly: When to use: Mixed AI tool environments where Claude Code and VS Code Copilot are both used. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** Here is the moment where the page starts to make sense. Learning Cards: Agents Window has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Listen for the small confirmations in this list. Open the Agents window from the Command Palette (Chat: Open Agents Window). Use Alt+F1 for Accessibility Help, F6/Shift+F6 to move between areas. Use F7/Shift+F7 for diff navigation, Alt+F2 for Accessible View. Listen for approval prompts before terminal commands. Prefer worktree isolation for safe review. Increase zoom (Ctrl+=), use high-contrast theme (Ctrl+K Ctrl+T).
 
 **Jamie:** Where do you want a learner to place their attention here?
 
-**Alex:** The reason this matters is simple: enable/disable: Set chat.useClaudeMdFile: true (default: on). The listener should be able to check this: Claude Rules format (for.claude/rules/ and /.claude/rules/).
+**Alex:** Settings and Limitations has three jobs: name the idea, give the learner a move, and show what counts as evidence.

Some extensions require opt-in. Agent cannot directly open integrated browser (use localhost link or command). Org policy may restrict agents/cloud/model choices.
 
-**Alex:** The next point gives the learner a handle. Do not treat 4D. Conditional / Scoped Instructions -.instructions.md as decoration. What it is: Instructions that apply only when specific file types or folders are involved in the chat. That is not trivia. More targeted than always-on instructions.

+**Alex:** If the interface shifts, Other VS Code 1.120 Changes Worth Calling Out is still useful because the following VS Code 1.120 release-note items are most relevant to this workshop.
 
-**Alex:** Hold that next to this. Put 4E. Organization-Level Instructions (GitHub Enterprise and Teams) into plain language. What it is: Organization administrators define custom instructions that apply to all repositories in the organization. The useful version is: Every team member automatically gets these instructions added to their Copilot context. The interface gets easier when it becomes a set of named places instead of a wall of controls.

Not every agent type or third-party agent is supported in the Agents window yet. Multi-root sessions are not supported in the Agents window yet. Some extensions work automatically, but extension support is still evolving. The agent cannot directly open the integrated browser for you; use a localhost link or Browser: Open Integrated Browser.

-**Alex:** Here is the practical turn. Learning Cards: Custom Instructions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the practical turn. Here is the learner-facing version. MCP is an open protocol (anthropic/model-context-protocol) that lets AI agents access tools and data sources through a standardized interface. Put another way, the Accessibility Agents project operates an HTTP-based MCP server with 30+ accessibility tools - no installation needed, just connect and scan. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
-**Alex:** On the ground, that means a few things. The three-level scope hierarchy (Organization, Workspace, User) means instructions can come from multiple places -- use Chat Diagnostics (gear icon in Chat header) to list every loaded instruction file and its source.github/copilot-instructions.md is always-on and requires no frontmatter -- just write plain Markdown; screen readers read the source file like any other Markdown document.instructions.md files use YAML frontmatter with applyTo globs -- the frontmatter is the first few lines between --- delimiters; arrow through carefully to verify syntax. The Diagnostics panel (Chat gear, then Diagnostics) lists loaded files in a scrollable pane -- increase font size in VS Code settings if the file paths are hard to read. YAML frontmatter is indentation-sensitive -- enable VS Code's indentation guides (editor.guides.indentation) and use a high-contrast theme so the guide lines are visible. The /init command auto-generates copilot-instructions.md from your workspace -- review the generated file in your editor at your preferred zoom before committing.
+**Alex:** On the ground, that means a few things. Use the same tools across different AI platforms (Copilot, Claude, Gemini, CI/CD). Tools work offline or in restricted environments via local HTTP server. Streaming responses with live progress updates. Compliance audit history and trending.

-
-**Alex:** NVDA / JAWS has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** How should a learner choose a tool without feeling judged by the choice?
 
-**Alex:** That becomes easier when you listen for these cues. Up/Down Arrow - read line by line. Ctrl+Home - jump to start. H - navigate by headings (if response has sections). Escape - close Accessible View, return to Chat.
+**Alex:** The reason this matters is simple: use MCP tools in GitHub Actions to run accessibility scans on every commit.

+**Alex:** Another way to ground it. Learning Cards: MCP Servers has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** If someone is taking notes, this is the short list. VO+Shift+Down - interact with the Accessible View content. Down Arrow - read line by line. VO+Escape - stop interacting. Escape - close Accessible View.
+**Alex:** If someone is taking notes, this is the short list. MCP servers work with any MCP client, including VS Code and Claude Desktop -- they expose tools through a standardized interface. The 30+ accessibility tools are named predictably: scan- for audits, export- for reporting, generate- for compliance. MCP tool responses appear in Copilot Chat like any agent output -- press Alt+F2 to read in Accessible View. MCP tools return structured JSON that Copilot renders as Markdown tables and lists -- zoom affects rendering the same as other Chat output. The export-findings-csv tool produces download links; use Ctrl+S to save CSV to your downloads folder. Generate reports with generate-audit-report for complete details; CSV export is for data analysis and trending.

-**Alex:** Learning Cards: Accessible View Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Think of this as 4 checks: Lightbulb menu: Click the lightbulb icon in the left margin of the editor (or press Ctrl+.); Git integration: Stage changes with git add; the commit panel offers "Generate Commit Message"; Error squiggles: Hover over an error and press Ctrl+. to see fixes; and Keyboard shortcut: Ctrl+. opens available actions for the current selection. That is the rhythm: orient, act, verify, continue.
 
-**Alex:** These are the pieces that turn the idea into a usable move. Press Alt+F2 immediately after sending a prompt -- Accessible View now streams dynamically so you can follow along in real time. Navigate Chat responses with Up/Down Arrow; headings, code blocks, and lists are structurally intact in the view. For inline suggestions, press Alt+F2 to read the full ghost text, then Ctrl+/ to insert it directly from the Accessible View. Accessible View renders Chat responses as a static, scrollable pane -- easier to read at high zoom than the streaming Chat panel. Code blocks in Accessible View preserve indentation and syntax -- pair with a high-contrast theme for maximum readability. Ctrl+Home jumps to the start of the response; Ctrl+End to the end -- useful for long multi-section outputs.
+**Alex:** Put that beside the next piece. Screen Reader & Low Vision Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Put that beside the next piece. This part earns its place because every Copilot customization file lives at one of three scopes. That gives the learner a foothold: VS Code combines all matching files from all scopes - it is additive, not winner-takes-all. That is the difference between following directions and owning the workflow.
+**Alex:** This is where the lesson becomes something you can check. When the lightbulb appears, VS Code announces it as a clickable action. Press Ctrl+. to open the actions list; it becomes a dropdown menu navigable with arrow keys. Each action is announced with a short description (e.g., "Generate Commit Message"). Press Enter to activate the selected action. Results appear as code suggestions or inline edits that you can review before accepting. The lightbulb icon is visible in the left margin when actions are available.

-**Jamie:** Let's pause on How Instructions Are Combined. What should a learner take away from it?
+**Alex:** The path is straightforward once it is named. Step one is review results in Chat and take action as needed. Each step should leave a trace you can name.
 
-**Alex:** The reason this matters is simple: result: Copilot follows TypeScript strict mode (from workspace), British English (from org), AND the Z-spelling override (from user, which overrides the org instruction on that specific point).
+**Jamie:** What is the safe way to learn from that example?
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open http://localhost:3000 and take a screenshot of the homepage.; Test the search form at localhost:8080 - enter "accessibility" and verify results appear.; Check the mobile layout of localhost:3000 at 320px width and report any overlapping text.; Verify the. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** For a learner, the useful signals are concrete. Organization: "Use British English spellings". Workspace: "Use TypeScript strict mode". User: "Use British English spellings - but use Z spellings (organize, not organise) for technical terms".
+**Alex:** Keep the thread going. Important: Browser Agent is Experimental has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Keep the thread going. Do not treat Priority Within the Same Scope as decoration. Within a single scope (e.g., workspace), all matching instructions files are combined with no inherent priority. That is not trivia. If two workspace-level.instructions.md files contradict each other, the behavior is undefined - avoid conflicting workspace instructions.

+**Jamie:** Let's pause on Accessibility & Testing Considerations. What should a learner take away from it?
+
+**Alex:** Accessibility & Testing Considerations has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The parts worth keeping in working memory are these. Browser Agent interactions are reported in Copilot Chat as text descriptions. Press Alt+F2 to read the full response in Accessible View. Screenshots taken by the agent appear as images in Chat (not screen-reader friendly). Request text descriptions instead: "Describe what you see on the page instead of taking a screenshot". Browser Agent can zoom the test environment independently of your VS Code zoom. Request large screenshots: "Take a screenshot at 150% zoom".
 
-**Alex:** If the interface shifts, Create any new customization file is still useful because ctrl+Shift+P → "Chat: New Instructions File" (or "New Prompt File", "New Agent File").
+**Alex:** Now slow down for the part people usually miss. Workshop Guidance has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Now slow down for the part people usually miss. Put 10. VS Code Settings Reference into plain language. All Copilot customization-related settings. The useful version is: Set in VS Code Settings (Ctrl+,) or settings.json. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** The room should hear these as checkpoints. Treat Browser Agent as a supplementary testing tool, not a replacement for manual testing. Teach learners to write clear test descriptions: "Check for visible text overlaps" vs. "Is it broken?". Use sparingly; each agent session consumes model tokens. For accessibility testing, prefer manual screen reader / keyboard testing + Browser Agent screenshots.
 
 **Jamie:** So this is less about memorizing and more about noticing.
 
 **Alex:** Right. Once the learner can name the move, the interface becomes much less intimidating.

+**Jamie:** Let's pause on 4E. Plan Agent. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. Prefer file-based instructions over these settings for new work. That is the difference between guessing and knowing: Each accepts an array with items: { "text": "." } (inline) or { "file": "relative/path" } (from file).
+**Alex:** The teaching point here is not the label; it is the move. The Plan Agent is a specialized Copilot agent that breaks down a task into a structured implementation plan before writing code.

+**Alex:** How Plan Agent Works has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The path is straightforward once it is named. Step one is ctrl+Shift+P → "Settings Sync: Turn On". Step two is ctrl+Shift+P → "Settings Sync: Configure". Step three is check "Prompts and Instructions". Keep it that plain: know where you are, make the move, check the result.
+**Alex:** The path is straightforward once it is named. Step one is start an agent session and describe your task. Step two is plan Agent analyzes your codebase structure and conventions. Step three is asks clarifying questions to understand requirements ("Should this use TypeScript or JavaScript?"). Step four is generates a plan with concrete steps, file changes, and testing approach. Keep it that plain: know where you are, make the move, check the result.
 
-**Jamie:** Give me the sequence, because order matters here.
+**Jamie:** Before we leave How Plan Agent Works, what is the practical point?
 
-**Alex:** View All Loaded Customizations: To see which instruction files, agents, prompts, and skills are currently loaded - and check for errors.
+**Alex:** First, you review and edit the plan inline (if editing is enabled). Then, handoff to implementation - either Plan Agent or another agent executes the plan. After that, agent runs tests and reports success or asks for refinement. Pause after each step and listen for the confirmation before moving on.
 
-**Alex:** Listen for the small confirmations in this list. All agents found and whether they loaded successfully. All prompt/instruction files and their source (workspace vs user vs organization). All skills and their discovery status. Any parse errors or invalid frontmatter.
+**Jamie:** Let's pause on When to Use Plan Agent. What should a learner take away from it?

+**Alex:** Here is the part to remember. Complex features requiring multi-file changes. Unfamiliar codebases where structure isn't obvious. When design review is important before implementation. When you want to validate the approach before committing. Team workflows where plan review is a step before coding.

The point is not speed; the point is never losing your place.
+**Alex:** Here is the part to remember. Plan Agent generates structured text outlines, easy to navigate with headings. Press H to jump between steps in the plan. Use Alt+F2 to read full plans in Accessible View. Inline plan editing (if enabled) is keyboard-friendly; Tab to edit fields. Plans are text-based with clear step numbers; zoom as needed. Headings are large and bold; navigate with heading jumps.

-**Jamie:** Turn that into a path someone can follow.
-
-**Alex:** .instructions.md file not loading automatically has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Walk it in order: Verify chat.includeApplyingInstructions is not set to false; Check the applyTo glob - test with " " temporarily to confirm the file loads at all; Confirm the file is in.github/instructions/ or a folder listed in chat.instructionsFilesLocations; and File extension must be.instructions.md exactly - not.md, not.instruction.md. Each step should leave a trace you can name.
+**Jamie:** What should feel predictable before the first live session starts?
 
-**Jamie:** Let's pause on Custom agent (@agent-name) not appearing. What should a learner take away from it?
+**Alex:** This is the move inside Workshop Guidance: introduce Plan Agent as a design-first approach.
 
-**Alex:** Custom agent (@agent-name) not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. Use it for larger features or refactors. Teach learners to ask clarifying questions back to the plan. Emphasize code review: "Is this plan what you expected?". Use Plan Agent output as documentation for your team.
 
-**Alex:** Think of this as 4 checks: File must be named.agent.md and placed in.github/agents/; Check YAML frontmatter for syntax errors - use a YAML validator; Confirm user-invocable is not set to false (which hides it from the picker); and Run Ctrl+Shift+P → "Reload Window" after any changes to agent files. If one step does not match what you hear, stop there and re-orient.
+**Alex:** Keep the teaching thread moving. Anchor this part on 4F. Copilot Spaces - Team Knowledge Base. Copilot Spaces (in preview) lets teams create a shared knowledge base that Copilot uses when answering questions. This is the part to say slowly: A Space includes documentation, codebases, and domain knowledge, all indexed for fast retrieval by AI.
 
-**Jamie:** Let's pause on Slash command (/command) not appearing. What should a learner take away from it?
+**Jamie:** Let's pause on What is a Copilot Space? What should a learner take away from it?
 
-**Alex:** Slash command (/command) not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** The reason this matters is simple: when someone uses Copilot in the Space, the AI uses that knowledge to provide more accurate, context-aware answers.
 
-**Alex:** The path is straightforward once it is named. Step one is file must be at.github/prompts/.prompt.md. Step two is extension must be.prompt.md exactly. Step three is reload VS Code: Ctrl+Shift+P → "Reload Window". That is the rhythm: orient, act, verify, continue.
+**Alex:** Here is the part to remember. Project documentation. Code repositories. Architectural guides. API documentation. Team conventions and style guides. Links to external resources.
 
 ---
 
-**Jamie:** Let's pause on Instructions from different files conflicting. What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Why Copilot Spaces Matter has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Instructions from different files conflicting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. Consistency: All team members get answers grounded in the same authoritative sources. Onboarding: New team members get expert-level context immediately. Domain expertise: Copilot learns your project's conventions, architecture, and best practices. Reduced hallucinations: Fewer wrong or outdated answers.
 
-**Alex:** First, open Diagnostics to see all loaded instruction files. Then, remove or edit conflicting instructions - they are not automatically de-duplicated. After that, user-level instructions override workspace instructions for the same topic. That small check between steps is what makes the workflow reliable.
+**Jamie:** Let's pause on How to Create a Copilot Space. What should a learner take away from it?
 
-**Jamie:** Let's pause on chat.instructionsFilesLocations not working. What should a learner take away from it?
+**Alex:** How to Create a Copilot Space has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** chat.instructionsFilesLocations not working has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. Link GitHub repositories. Add documentation links (GitHub Pages, wikis, external docs). Upload or reference team guides.
 
-**Alex:** The useful version is not abstract; it sounds like this. Path must be a folder path, not a file path. Use forward slashes or escaped backslashes. Relative paths are relative to the workspace root.
+**Alex:** Start here: Go to github.com/copilot/spaces. Then: Click Create a new Space. Next: Name your Space (e.g., "My Project Team"). Last: Add repositories and documentation. The sequence works because every action has a confirmation.
 
-**Alex:** Keep the teaching thread moving. Put 12. Screen Reader Workflow - Official Guide into plain language. Source: accessibility.github.com/documentation/guide/github-copilot-vsc/ Contributors: @mlama007, zersiax Community: GitHub Accessibility Discussions.
+**Jamie:** Before we leave How to Create a Copilot Space, what is the practical point?
 
----
+**Alex:** Walk it in order: Configure access (public, private, organization-only); and Save and share the Space URL with your team. Keep it that plain: know where you are, make the move, check the result.
 
-**Jamie:** Let's pause on Prerequisites. What should a learner take away from it?
+**Jamie:** Let's pause on Using a Copilot Space. What should a learner take away from it?
 
-**Alex:** Prerequisites has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Using a Copilot Space has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The parts worth keeping in working memory are these. Current VS Code with built-in AI features enabled, or an older managed VS Code build where Copilot has been enabled by your administrator. A GitHub account with Copilot access (Free tier or paid). A screen reader (NVDA recommended for this guide).
+**Alex:** Walk it in order: Open Copilot Chat in VS Code or GitHub; Select your Space from the Space picker (top of Chat); and Ask questions - Copilot uses the Space knowledge. Keep it that plain: know where you are, make the move, check the result.
 
-**Jamie:** Let's pause on Step 1: Enable VS Code Screen Reader Mode. What should a learner take away from it?
+**Jamie:** Before we leave Using a Copilot Space, what is the practical point?
 
-**Alex:** This part earns its place because when Screen Reader Mode is on, VS Code changes how it announces suggestions (full text instead of streaming), adjusts live regions, and enables accessible navigation patterns throughout the editor. That is the difference between following directions and owning the workflow.
+**Alex:** Think of this as 1 checks: Copilot searches the Space and returns context-aware answers. Pause after each step and listen for the confirmation before moving on.
 
-**Alex:** The path is straightforward once it is named. Step one is press Shift+Alt+F1 to toggle Screen Reader Accessibility Mode. Step two is or use Command Palette: Ctrl+Shift+P → "Toggle Screen Reader Accessibility Mode". Step three is VS Code announces: "Screen Reader Accessibility Mode enabled". The point is not speed; the point is never losing your place.

-**Jamie:** Let's pause on Step 2: Configure Accessibility Signals (Optional but Recommended). What should a learner take away from it?
+**Jamie:** Let's pause on Accessibility & Team Workflows. What should a learner take away from it?
 
-**Alex:** Step 2: Configure Accessibility Signals (Optional but Recommended): Recommended JSON config for Copilot accessibility signals.
+**Alex:** Accessibility & Team Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** First, open Settings: Ctrl+,. Then, search "accessibility signals". After that, enable the Copilot-specific signals. Each step should leave a trace you can name.
+**Alex:** Here is the part to remember. Space configuration is fully keyboard-accessible on github.com. Use H to navigate section headings when setting up a Space. The Space picker in Chat is a keyboard-navigable dropdown. Documentation links in the Space are announced as regular links. Space configuration has good color contrast on GitHub.com. Zoom in on the Space picker to see available options.
 
----
+**Alex:** Keep the teaching thread moving. Workshop Guidance has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. This is the complete table of Copilot screen reader shortcuts as published by the GitHub Accessibility team.
+**Alex:** Here is the part to remember. Treat Copilot Spaces as an advanced team feature (not for individual learners). If your workshop uses an organization Space, mention it as a reference context for facilitators. Point out: "Your facilitator may have created a Copilot Space with workshop documentation. Select it from the Space picker to get team-specific answers.". Link to Spaces documentation as a post-workshop resource.
 
-**Jamie:** How do you keep commands from becoming magic words?
+**Jamie:** Let's pause on 5. Custom Instructions - All Levels. What should a learner take away from it?
 
-**Alex:** This is the move inside The screen reader-optimized workflow for every inline suggestion: this workflow avoids the streaming announcement problem (where suggestions are read out in fragments as tokens arrive) and gives you full, uninterrupted access to the suggestion text before committing.
+**Alex:** 5. Custom Instructions - All Levels: GitHub Copilot supports multiple ways to provide custom instructions. The next useful detail is concrete: They differ by scope, priority, trigger mechanism, and which tools recognize them.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Type your code or documentation; 2. Copilot generates a suggestion (audio cue sounds if enabled); 3. DO NOT press Tab immediately; 4. Press Alt+F2 - Accessible View opens with the full suggestion text; 5. Read the suggestion at your own pace with Arrow keys. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+---
 
-**Jamie:** Let's pause on Step 5: Recommended Workflow for Chat Responses. What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. What it is: The primary VS Code Copilot instruction file. Put another way, content is automatically included in every chat request and inline suggestion context - you never need to invoke it.
 
-**Alex:** Step 5: Recommended Workflow for Chat Responses has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on Auto-generate with /init. What should a learner take away from it?
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Chat: Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs; 2. Type your prompt, press Ctrl+Enter to send; 3. Press Alt+F2 - Accessible View opens immediately; the response streams live into it; 4. Navigate with Arrow keys -. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** Auto-generate with /init has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
----
+**Alex:** Walk it in order: Open Copilot Chat; Type /init; VS Code analyzes your workspace and generates a tailored copilot-instructions.md; and Review and edit the result before committing. That is the rhythm: orient, act, verify, continue.
 
-**Jamie:** Let's pause on Reading the Suggestions Panel (Ctrl+Enter). What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Anchor this part on 4B. Always-On Instructions - AGENTS.md (Multi-Tool / Monorepo). What it is: An open standard instruction file recognized by multiple AI tools - GitHub Copilot, Claude Code, Gemini CLI, and others. This is the part to say slowly: Use this instead of copilot-instructions.md when you want one instruction file that works across all AI coding assistants. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
 
-**Alex:** The reason this matters is simple: pressing Ctrl+Enter opens a Suggestions Panel - a separate editor tab that shows up to 10 alternative suggestions simultaneously. The listener should be able to check this: This is useful when the default suggestion isn't quite right and you want to compare options.
+---
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Ctrl+Enter - opens "GitHub Copilot" editor tab; 2. Screen Reader Mode is active: navigate with Browse Mode; 3. H key to navigate headings (each suggestion may be under a heading); 4. Press Alt+F2 on a focused suggestion to read it in Accessible View; 5. Tab to. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Jamie:** Let's pause on 4C. Always-On Instructions - CLAUDE.md (Cross-Tool Compatibility). What should a learner take away from it?
 
-**Alex:** Keep the teaching thread moving. Learning Cards: Screen Reader Copilot Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** The reason this matters is simple: what it is: Instructions file originally from Claude Code that VS Code Copilot also recognizes. The listener should be able to check this: When to use: Mixed AI tool environments where Claude Code and VS Code Copilot are both used.
 
-**Alex:** The room should hear these as checkpoints. The golden rule: never accept a suggestion with Tab before reviewing it -- press Alt+F2 first, read it, then Ctrl+/ to insert. Enable the four Copilot audio signals (inline suggestion, request sent, response pending, response received) for non-verbal status awareness. Ctrl+Enter opens a Suggestions Panel with up to 10 alternatives -- navigate with H for headings, then Tab to the Accept button. Inline ghost text is typically rendered in a muted color -- if hard to see, rely on the lineHasInlineSuggestion audio signal instead. The Suggestions Panel (Ctrl+Enter) shows alternatives in a full editor tab at your current font size and theme. Chat responses are easier to read in Accessible View than in the streaming panel, especially at high zoom.
+**Alex:** Keep the teaching thread moving. Do not treat Supported locations as decoration. Enable/disable: Set chat.useClaudeMdFile: true (default: on). That is not trivia. Claude Rules format (for.claude/rules/ and /.claude/rules/).
 
-**Jamie:** Let's pause on 13. awesome-copilot - Plugin Ecosystem. What should a learner take away from it?
+**Jamie:** Let's pause on 4D. Conditional / Scoped Instructions -.instructions.md. What should a learner take away from it?
 
-**Alex:** If the interface shifts, 13. awesome-copilot - Plugin Ecosystem is still useful because awesome-copilot is a GitHub repository (github/awesome-copilot) - not a VS Code Marketplace extension. For someone navigating by keyboard or screen reader, this detail matters: It is GitHub's curated ecosystem of Copilot plugins, prompts, instructions, agents, skills, and hooks that can be shared and discovered by anyone.
+**Alex:** If the interface shifts, 4D. Conditional / Scoped Instructions -.instructions.md is still useful because what it is: Instructions that apply only when specific file types or folders are involved in the chat. For someone navigating by keyboard or screen reader, this detail matters: More targeted than always-on instructions.

-**Alex:** Keep the teaching thread moving. Put Repository Structure into plain language. LLM discovery: https://github.github.io/awesome-copilot/llms.txt - a machine-readable index of all available resources. The interface gets easier when it becomes a set of named places instead of a wall of controls.
-
-**Jamie:** Let's pause on The /plugin Command - Browse and Install from Chat. What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Create an instructions file has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The teaching point here is not the label; it is the move. The easiest way to explore awesome-copilot from VS Code.
+**Alex:** Here is the part to remember. Ctrl+Shift+P → "Chat: New Instructions File" → choose scope (Workspace or User). Or create the file manually in.github/instructions/.
 
-**Alex:** Think of this as 4 checks: Open Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette; Type /plugin and press Enter; Copilot Chat opens an interactive plugin marketplace browser; and Browse plugins by category, read descriptions, and install with a single command. Each step should leave a trace you can name.
+**Jamie:** Let's pause on 4E. Organization-Level Instructions (GitHub Enterprise and Teams). What should a learner take away from it?
 
-**Jamie:** Let's pause on CLI Plugin Installation. What should a learner take away from it?
+**Alex:** The teaching point here is not the label; it is the move. What it is: Organization administrators define custom instructions that apply to all repositories in the organization. That is the difference between guessing and knowing: Every team member automatically gets these instructions added to their Copilot context.
 
-**Alex:** This part earns its place because from any terminal with GitHub CLI (gh) installed.
+**Alex:** Keep the teaching thread moving. This part earns its place because use for: Organization-wide coding standards, security policies, legal disclaimers (open source license obligations), toolchain conventions.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Browse the marketplace; gh copilot plugin marketplace list; Add the awesome-copilot collection; gh copilot plugin marketplace add github/awesome-copilot; Install a specific plugin; gh copilot plugin install @awesome-copilot/accessibility-toolkit; List what you. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** Here is the part to remember. GitHub Enterprise or Teams plan with Copilot enabled. Admin configures instructions in organization settings on GitHub.com. Each user must enable discovery in VS Code.

-**Jamie:** Let's pause on MCP Server Integration (Docker required). What should a learner take away from it?
+**Jamie:** Let's pause on 4F. Settings-Based Instructions (Deprecated - Use Files Instead). What should a learner take away from it?
 
-**Alex:** MCP Server Integration (Docker required): awesome-copilot also ships as an MCP (Model Context Protocol) Server - a Docker-based tool server that extends Copilot with additional capabilities beyond file-based customizations. The next useful detail is concrete: Install in VS Code by clicking the button at https://aka.ms/awesome-copilot/mcp/vscode, or add manually to settings.json.
+**Alex:** 4F. Settings-Based Instructions (Deprecated - Use Files Instead): These settings-based instructions are deprecated and may be removed in a future VS Code release. The next useful detail is concrete: For new work, use copilot-instructions.md or.instructions.md files.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like {; "mcp": {; "servers": {; "awesome-copilot": {; "type": "stdio",; "command": "docker",; "args": [; "run", "-i", "--rm",; "ghcr.io/github/awesome-copilot-mcp:latest"; ]; }; }; }; }. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Jamie:** What decision is this helping them make?
+
+**Alex:** 4G. Comparison - When to Use Each Approach has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Approach means Always-on? means Multi-tool? means Best. copilot-instructions.md means Workspace means VS Code only means Primary project instructions. AGENTS.md means Workspace + monorepo means All AI tools means Multi-tool teams or large monorepos.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Status: Technical Preview - GitHub Agentic Workflows entered technical preview on February 13, 2026. Put another way, as of May 2026 the feature remains in active development and preview; changes to the API and workflow format are ongoing. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Jamie:** Let's pause on Learning Cards: Custom Instructions. What should a learner take away from it?
 
-**Jamie:** Let's pause on What This Enables. What should a learner take away from it?
+**Alex:** Learning Cards: Custom Instructions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** This is the move inside What This Enables: browse 50+ community-built workflows at Peli's Agent Factory.
+**Alex:** Here is the part to remember. The three-level scope hierarchy (Organization, Workspace, User) means instructions can come from multiple places -- use Chat Diagnostics (gear icon in Chat header) to list every loaded instruction file and its source.github/copilot-instructions.md is always-on and requires no frontmatter -- just write plain Markdown; screen readers read the source file like any other Markdown document.instructions.md files use YAML frontmatter with applyTo globs -- the frontmatter is the first few lines between --- delimiters; arrow through carefully to verify syntax. The Diagnostics panel (Chat gear, then Diagnostics) lists loaded files in a scrollable pane -- increase font size in VS Code settings if the file paths are hard to read. YAML frontmatter is indentation-sensitive -- enable VS Code's indentation guides (editor.guides.indentation) and use a high-contrast theme so the guide lines are visible. The /init command auto-generates copilot-instructions.md from your workspace -- review the generated file in your editor at your preferred zoom before committing.
 
 ---
 
-**Alex:** Keep the teaching thread moving. Anchor this part on How It Works. The gh aw CLI (a gh extension) compiles.md workflow files into.lock.yml GitHub Actions workflows. This is the part to say slowly: The AI agent (GitHub Copilot, Claude, or OpenAI Codex) reads your repository context and the natural language instructions, then performs the task using the GitHub MCP Server and other available tools.
+**Alex:** Keep the teaching thread moving. Anchor this part on 6. Accessible View Workflow. Copilot Chat responses stream in token by token, which can fragment screen reader announcements. This is the part to say slowly: Accessible View (Alt+F2) gives you a complete, static, properly structured version of the response.
 
-**Jamie:** Let's pause on Workflow Format - Markdown with Frontmatter. What should a learner take away from it?
+**Jamie:** How do you keep commands from becoming magic words?
+
+**Alex:** The reason this matters is simple: VS Code December 2025: The Accessible View now streams dynamically. The listener should be able to check this: You can open it immediately after sending a prompt and follow the response as it arrives - no need to wait for the response to finish before pressing Alt+F2.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Copilot Chat: Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs; 2. Type your prompt; 3. Press Ctrl+Enter to send; 4. Press Alt+F2 to open Accessible View (open immediately - no need to wait); 5. Follow as the response. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** The reason this matters is simple: unlike standard GitHub Actions (YAML), agentic workflows are Markdown files. The listener should be able to check this: The body is natural language - describe what you want the AI agent to do.
+**Alex:** Keep the teaching thread moving. NVDA / JAWS has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Keep the teaching thread moving. Do not treat Security Model - "Safe Outputs" as decoration. Workflows run read-only by default with sandboxed execution, network isolation, and SHA-pinned dependencies. That is not trivia. Write operations require explicit declaration in safe-outputs - a set of pre-approved, sanitized GitHub operations. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+**Alex:** Here is the part to remember. Up/Down Arrow - read line by line. Ctrl+Home - jump to start. H - navigate by headings (if response has sections). Escape - close Accessible View, return to Chat.
 
 ---
 
-**Jamie:** Let's pause on Getting Started with gh aw. What should a learner take away from it?
+**Jamie:** Let's pause on VoiceOver. What should a learner take away from it?
 
-**Alex:** Getting Started with gh aw has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** VoiceOver has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Install the CLI extension; gh extension install github/gh-aw; Create a new workflow interactively (from github.com or VS Code also works); gh aw create; Compile your Markdown workflow to a GitHub Actions.lock.yml; gh aw. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** Here is the part to remember. VO+Shift+Down - interact with the Accessible View content. Down Arrow - read line by line. VO+Escape - stop interacting. Escape - close Accessible View.
 
-**Jamie:** Let's pause on Monitoring Agentic Workflow Runs. What should a learner take away from it?
+**Jamie:** Let's pause on Accessible View for Inline Suggestions. What should a learner take away from it?
 
-**Alex:** Monitoring Agentic Workflow Runs has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Put Accessible View for Inline Suggestions into plain language. When a multi-line ghost text suggestion appears in the editor. The useful version is: This is especially important for multi-line suggestions where ghost text is hard to review incrementally.
 
-**Alex:** Walk it in order: Navigate to the Actions tab of your repository (D → Repository navigation → K to Actions); Find the workflow by name (h3 headings, navigate with 3); Press Enter to open a specific run; and Expand job steps to read the agent output log and any safe-outputs created. If one step does not match what you hear, stop there and re-orient.
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Do not accept immediately; 2. Press Alt+F2; 3. Accessible View shows: "Suggestion: [full text]"; 4. Read the complete suggestion at your own pace; 5. Press Escape to close; 6. Press Tab to accept, or Escape to reject. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Jamie:** Let's pause on Resources. What should a learner take away from it?
+**Jamie:** Let's pause on Accessible View for Code Blocks. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. Relationship to Accessibility Agents: Accessibility Agents agents (.agent.md files) are designed for interactive use inside VS Code. That is the difference between guessing and knowing: GitHub Agentic Workflows are a separate, cloud-native system that uses its own Markdown workflow format and the gh aw CLI - they are complementary tools, not the same mechanism.
+**Alex:** Accessible View for Code Blocks has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
----
+**Alex:** Here is the part to remember. Code blocks appear inside elements in Accessible View. Screen readers announce "code block" or "pre-formatted text" at the start. Each line is on its own line (not run together). Indentation is preserved.
 
-**Alex:** Keep the teaching thread moving. Learning Cards: GitHub Agentic Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+---
 
-**Alex:** Here is what that changes in practice. Agentic workflow runs appear in the Actions tab of your repository -- navigate to Actions with T (tab bar), then use heading navigation (3) to jump between workflow run entries. Workflow files are Markdown (.md) not YAML -- the frontmatter at the top controls triggers and permissions; the body is natural language instructions the AI agent reads. The safe-outputs frontmatter property lists every write operation the agent is allowed to perform -- review this section carefully since it is the security boundary. The Actions tab lists workflow runs with status icons (green check, red X, yellow circle) -- at high zoom, also look for the text status label next to each run name. Workflow.md files use the same Markdown rendering as any other file in the repo -- edit them in VS Code with your preferred font size and theme. The gh aw compile command generates a.lock.yml file alongside your.md file -- both appear in the file explorer; the.lock.yml is auto-generated and should not be edited manually.
+**Alex:** Keep the teaching thread moving. Learning Cards: Accessible View Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Let's pause on Copilot Models. What should a learner take away from it?
+**Alex:** Here is the part to remember. Press Alt+F2 immediately after sending a prompt -- Accessible View now streams dynamically so you can follow along in real time. Navigate Chat responses with Up/Down Arrow; headings, code blocks, and lists are structurally intact in the view. For inline suggestions, press Alt+F2 to read the full ghost text, then Ctrl+/ to insert it directly from the Accessible View. Accessible View renders Chat responses as a static, scrollable pane -- easier to read at high zoom than the streaming Chat panel. Code blocks in Accessible View preserve indentation and syntax -- pair with a high-contrast theme for maximum readability. Ctrl+Home jumps to the start of the response; Ctrl+End to the end -- useful for long multi-section outputs.
 
-**Alex:** Copilot Models has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on 7. Configuration Scope Reference. What should a learner take away from it?
 
-**Alex:** This is where the lesson becomes something you can check. Overview. How to Choose a Model. Current Model and Billing Sources. Model Availability by Plan. GitHub AI Credits and Usage. Switching Models in VS Code.
+**Alex:** 7. Configuration Scope Reference: Every Copilot customization file lives at one of three scopes. The next useful detail is concrete: VS Code combines all matching files from all scopes - it is additive, not winner-takes-all.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. GitHub Copilot offers access to AI models from multiple providers including OpenAI, Anthropic, Google, and others. Put another way, the model you choose affects response quality, speed, and usage cost.
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Files committed to your repository. Put another way, everyone who clones the repo gets them.

-**Jamie:** Let's pause on 2. How to Choose a Model. What should a learner take away from it?
+**Jamie:** Let's pause on User / Personal - Follows You Across Workspaces. What should a learner take away from it?
 
-**Alex:** This is the move inside 2. How to Choose a Model: GitHub Docs organizes models by task. That matters in practice: Match your task to the right level of capability instead of memorizing a model name.
+**Alex:** This is the move inside User / Personal - Follows You Across Workspaces: files in your VS Code profile folder. That matters in practice: Available in every workspace you open.
 
-**Alex:** Keep the teaching thread moving. Anchor this part on Everyday coding and writing. Use the default or Auto selection for short explanations, Markdown drafting, commit messages, PR descriptions, and small refactors. This is the part to say slowly: For this workshop, this is the safest starting point. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** Keep the teaching thread moving. Anchor this part on Organization - GitHub-Configured (Enterprise/Teams). Configured by administrators in GitHub organization settings. This is the part to say slowly: Automatically applied to all organization members. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
 
-**Jamie:** How should someone ask for help in a way that gets them unstuck faster?
+**Alex:** Here is the part to remember. Enable discovery: github.copilot.chat.organizationInstructions.enabled: true. Lowest priority - workspace and user instructions override when there is a conflict.
+
+**Jamie:** Let's pause on 8. Instruction Priority and Conflicts. What should a learner take away from it?
 
-**Alex:** The reason this matters is simple: use lighter models for quick answers, boilerplate, simple rewrites, and short command explanations. The listener should be able to check this: This helps preserve included usage when billing is usage-based.
+**Alex:** The reason this matters is simple: when multiple instruction sources give conflicting guidance, VS Code uses this priority order. The listener should be able to check this: This priority applies to conflicts.
 
 ---
 
-**Alex:** Keep the teaching thread moving. Do not treat Deep reasoning and debugging as decoration. Use more capable models for architecture questions, unfamiliar codebases, multi-file reasoning, and difficult debugging. That is not trivia. These interactions typically consume more usage because they process more context and generate longer responses.
+**Alex:** Keep the teaching thread moving. Do not treat How Instructions Are Combined as decoration. Result: Copilot follows TypeScript strict mode (from workspace), British English (from org), AND the Z-spelling override (from user, which overrides the org instruction on that specific point).
 
-**Jamie:** Let's pause on Agentic software development. What should a learner take away from it?
+**Alex:** Here is the part to remember. Organization: "Use British English spellings". Workspace: "Use TypeScript strict mode". User: "Use British English spellings - but use Z spellings (organize, not organise) for technical terms".
+
+**Jamie:** Let's pause on Priority Within the Same Scope. What should a learner take away from it?
 
-**Alex:** If the interface shifts, Agentic software development is still useful because agent mode, Copilot CLI, Copilot cloud agent, and third-party coding agents can make multiple model calls within one task. For someone navigating by keyboard or screen reader, this detail matters: Use them for scoped, valuable work rather than casual exploration, especially when working under a limited plan.
+**Alex:** If the interface shifts, Priority Within the Same Scope is still useful because within a single scope (e.g., workspace), all matching instructions files are combined with no inherent priority. For someone navigating by keyboard or screen reader, this detail matters: If two workspace-level.instructions.md files contradict each other, the behavior is undefined - avoid conflicting workspace instructions.
 
-**Alex:** Keep the teaching thread moving. Put Working with visuals into plain language. Check the model picker and the official supported-models documentation before planning an exercise that depends on screenshots or image analysis. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** Keep the teaching thread moving. Put Create any new customization file into plain language. Ctrl+Shift+P → "Chat: New Instructions File" (or "New Prompt File", "New Agent File"). The interface gets easier when it becomes a set of named places instead of a wall of controls.

-**Jamie:** Let's pause on 3. Current Model and Billing Sources. What should a learner take away from it?
+**Jamie:** Let's pause on 10. VS Code Settings Reference. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. The following table lists the official sources to use instead of static model tables in this curriculum.
+**Alex:** The teaching point here is not the label; it is the move. All Copilot customization-related settings. That is the difference between guessing and knowing: Set in VS Code Settings (Ctrl+,) or settings.json.
 
-**Alex:** Keep the teaching thread moving. Source-backed facts verified May 12, 2026 has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. This part earns its place because prefer file-based instructions over these settings for new work. That gives the learner a foothold: each accepts an array with items: { "text": "." } (inline) or { "file": "relative/path" } (from file).
 
-**Alex:** Here is the part to remember. GitHub Copilot moves to usage-based billing on June 1, 2026. Premium request units are being replaced by GitHub AI Credits. One GitHub AI Credit equals $0.01 USD in the usage-based billing documentation. Copilot Chat, Copilot CLI, Copilot cloud agent, Copilot Spaces, Spark, and third-party coding agents consume AI Credits. Code completions and next edit suggestions are not billed in AI Credits for paid plans. Copilot code review is expected to consume GitHub Actions minutes in addition to GitHub AI Credits starting June 1, 2026.
+**Jamie:** Let's pause on Settings Sync. What should a learner take away from it?
 
-**Jamie:** Let's pause on 4. Model Availability by Plan. What should a learner take away from it?
+**Alex:** Settings Sync: To sync your personal prompts, instructions, and agents across devices. The next useful detail is concrete: Your personal.instructions.md,.agent.md, and.prompt.md files will sync to all signed-in VS Code instances.
 
-**Alex:** 4. Model Availability by Plan: Plan names, included usage, and model access can change by date, account type, organization policy, region, and rollout. The next useful detail is concrete: Do not copy plan limits from this appendix into learner instructions.
+**Alex:** First, ctrl+Shift+P → "Settings Sync: Turn On". Then, ctrl+Shift+P → "Settings Sync: Configure". After that, check "Prompts and Instructions". Pause after each step and listen for the confirmation before moving on.
 
 ---
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Check GitHub Copilot settings for your account and the GitHub Copilot plans page for current public plan details. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Jamie:** Let's pause on View All Loaded Customizations. What should a learner take away from it?
 
-**Alex:** Here is the part to remember. Copilot Free can support short, focused workshop prompts, but it has monthly limits. Verified students may have access to GitHub Copilot Student plan benefits. Organization and enterprise users may have Copilot access managed by an administrator. Paid plans include more usage and broader feature access, but the billing unit changes to GitHub AI Credits on June 1, 2026. Annual individual plans may follow transition rules that differ from monthly plans.
+**Alex:** Here is the learner-facing version. To see which instruction files, agents, prompts, and skills are currently loaded - and check for errors. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
-**Jamie:** Let's pause on 5. GitHub AI Credits and Usage. What should a learner take away from it?
+**Alex:** Here is the part to remember. All agents found and whether they loaded successfully. All prompt/instruction files and their source (workspace vs user vs organization). All skills and their discovery status. Any parse errors or invalid frontmatter.
 
-**Alex:** This is the move inside 5. GitHub AI Credits and Usage: usage-based billing measures Copilot usage with GitHub AI Credits. That matters in practice: The cost of an interaction depends on the selected model and the tokens used for input, output, and cached context.
+**Alex:** Start here: Configure Chat Gear: Click the gear () icon in the Copilot Chat header → "Diagnostics". Then: Right-click method: Right-click in the Chat view → "Diagnostics". The point is not speed; the point is never losing your place.
 
-**Alex:** Keep the teaching thread moving. Tips for managing usage has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on copilot-instructions.md not being followed. What should a learner take away from it?
 
-**Alex:** Here is the part to remember. Use Auto model selection unless the facilitator gives a specific reason to choose a model. Keep workshop prompts focused and short. Ask one clear question at a time when using Copilot Free or any limited plan. Use agentic features for meaningful multi-step tasks, not casual exploration. Review model badges, model picker details, and usage dashboards when they are available in your account. Prefer code completions and next edit suggestions for simple local edits because paid-plan documentation says those are not billed in AI Credits.
+**Alex:** copilot-instructions.md not being followed has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
----
+**Alex:** Walk it in order: Confirm the file is at exactly.github/copilot-instructions.md (relative to workspace root); Check the file is plain Markdown with no frontmatter syntax errors; Open Diagnostics to confirm it appears in the loaded files list; and Some instructions work better with specific phrasing; use imperative mood ("Always use."). Each step should leave a trace you can name.
 
-**Jamie:** Let's pause on In the Chat Panel. What should a learner take away from it?
+**Jamie:** Let's pause on.instructions.md file not loading automatically. What should a learner take away from it?
 
-**Alex:** In the Chat Panel has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** .instructions.md file not loading automatically has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The path is straightforward once it is named. Step one is open the Chat panel (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette. Step two is at the bottom of the chat input area, you'll see the current model name as a button, often Auto or a specific model name. Step three is activate the model picker button - this opens a dropdown list of available models. Step four is arrow through the list and press Enter to select a model. That is the rhythm: orient, act, verify, continue.
+**Alex:** Think of this as 4 checks: Verify chat.includeApplyingInstructions is not set to false; Check the applyTo glob - test with " " temporarily to confirm the file loads at all; Confirm the file is in.github/instructions/ or a folder listed in chat.instructionsFilesLocations; and File extension must be.instructions.md exactly - not.md, not.instruction.md. If one step does not match what you hear, stop there and re-orient.
 
-**Jamie:** Before we leave In the Chat Panel, what is the practical point?
+---
 
-**Alex:** First, for screen reader users: the chat input will announce the newly selected model after switching. That small check between steps is what makes the workflow reliable.
+**Jamie:** Let's pause on Custom agent (@agent-name) not appearing. What should a learner take away from it?
 
-**Jamie:** Let's pause on In an Inline Chat Session. What should a learner take away from it?
+**Alex:** Custom agent (@agent-name) not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** In an Inline Chat Session has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** The path is straightforward once it is named. Step one is file must be named.agent.md and placed in.github/agents/. Step two is check YAML frontmatter for syntax errors - use a YAML validator. Step three is confirm user-invocable is not set to false (which hides it from the picker). Step four is run Ctrl+Shift+P → "Reload Window" after any changes to agent files. That is the rhythm: orient, act, verify, continue.
 
-**Alex:** First, open Inline Chat (Ctrl+I / Cmd+I). Then, the model picker appears in the inline chat toolbar. After that, same interaction: activate the model button to switch. That small check between steps is what makes the workflow reliable.
+**Jamie:** Let's pause on Slash command (/command) not appearing. What should a learner take away from it?
 
-**Jamie:** Let's pause on Keyboard Note for Screen Readers. What should a learner take away from it?
+**Alex:** Slash command (/command) not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** If the interface shifts, Keyboard Note for Screen Readers is still useful because in the Chat panel, the model picker button is near the bottom of the chat view. For someone navigating by keyboard or screen reader, this detail matters: If you're having trouble locating it.
+**Alex:** First, file must be at.github/prompts/.prompt.md. Then, extension must be.prompt.md exactly. After that, reload VS Code: Ctrl+Shift+P → "Reload Window". That small check between steps is what makes the workflow reliable.
 
-**Alex:** Here is the part to remember. Tab through the bottom toolbar of the chat panel. Listen for the model name announced - it appears between the "Attach" button and the send button. Press Space or Enter to open the picker.
+**Jamie:** Let's pause on Instructions from different files conflicting. What should a learner take away from it?
+
+**Alex:** Instructions from different files conflicting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Start here: Open Diagnostics to see all loaded instruction files. Then: Remove or edit conflicting instructions - they are not automatically de-duplicated. Next: User-level instructions override workspace instructions for the same topic. The sequence works because every action has a confirmation.
 
 ---
 
-**Alex:** Keep the teaching thread moving. Put 7. Auto Model Selection into plain language. Auto mode lets Copilot choose the best model based on the type of request.
+**Alex:** Keep the teaching thread moving. chat.instructionsFilesLocations not working has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Let's pause on How Auto works. What should a learner take away from it?
+**Alex:** Here is the part to remember. Path must be a folder path, not a file path. Use forward slashes or escaped backslashes. Relative paths are relative to the workspace root.
 
-**Alex:** How Auto works has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on 12. Screen Reader Workflow - Official Guide. What should a learner take away from it?
 
-**Alex:** Here is the part to remember. For simple questions, Copilot routes to a faster, lighter model. For complex code generation or debugging, Copilot upgrades to a more capable model automatically. For agent tasks, Copilot selects an appropriate Codex model. You may be able to see which model was used after each response. VS Code 1.119 and later can show model details and multipliers for some Copilot CLI and agent responses.
+**Alex:** The teaching point here is not the label; it is the move. Source: accessibility.github.com/documentation/guide/github-copilot-vsc/ Contributors: @mlama007, zersiax Community: GitHub Accessibility Discussions.
 
-**Alex:** Keep the teaching thread moving. This part earns its place because to switch back to Auto from a specific model, re-open the model picker and select Auto at the top of the list. That is the difference between following directions and owning the workflow.
+**Alex:** Keep the teaching thread moving. Prerequisites has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. You specifically need a model with certain capabilities, such as image input. You're managing usage and want to control costs. You've found a particular model gives better results for your specific workflow or domain. You're doing agentic work and want to explicitly select an agent-optimized Codex model (check current availability in the model picker).
+**Alex:** Here is the part to remember. Current VS Code with built-in AI features enabled, or an older managed VS Code build where Copilot has been enabled by your administrator. A GitHub account with Copilot access (Free tier or paid). A screen reader (NVDA recommended for this guide).
 
 ---
 
-**Jamie:** Let's pause on 8. Models Retiring Soon. What should a learner take away from it?
+**Jamie:** Let's pause on Step 1: Enable VS Code Screen Reader Mode. What should a learner take away from it?
 
-**Alex:** 8. Models Retiring Soon: GitHub regularly updates the model roster. The next useful detail is concrete: Older model versions are retired when newer equivalents are available.
+**Alex:** Step 1: Enable VS Code Screen Reader Mode: When Screen Reader Mode is on, VS Code changes how it announces suggestions (full text instead of streaming), adjusts live regions, and enables accessible navigation patterns throughout the editor.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. The April-May 2026 GitHub Copilot changelog included retirements and deprecations for several model families. Put another way, treat any named model in workshop materials as a temporary example, not a guarantee.
+**Alex:** First, press Shift+Alt+F1 to toggle Screen Reader Accessibility Mode. Then, or use Command Palette: Ctrl+Shift+P → "Toggle Screen Reader Accessibility Mode". After that, VS Code announces: "Screen Reader Accessibility Mode enabled". Each step should leave a trace you can name.
 
-**Jamie:** Let's pause on Related Resources. What should a learner take away from it?
+**Jamie:** Let's pause on Step 2: Configure Accessibility Signals (Optional but Recommended). What should a learner take away from it?
 
-**Alex:** This is the move inside Related Resources: next: Appendix L: Agents Reference Back: Appendix J: Codespaces Teaching chapter: Chapter 16: GitHub Copilot.
+**Alex:** Here is the learner-facing version. Recommended JSON config for Copilot accessibility signals.
 
----
+**Alex:** Start here: Open Settings: Ctrl+,. Then: Search "accessibility signals". Next: Enable the Copilot-specific signals. If one step does not match what you hear, stop there and re-orient.
 
-**Jamie:** What should people carry with them after this?
+**Jamie:** Let's pause on Step 3: Official Shortcut Table (from accessibility.github.com). What should a learner take away from it?
 
-**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+**Alex:** This is the move inside Step 3: Official Shortcut Table (from accessibility.github.com): this is the complete table of Copilot screen reader shortcuts as published by the GitHub Accessibility team.
 
-**Jamie:** That is a better way to say it than just follow the steps.
+---
 
-**Alex:** Right. Steps matter, but understanding wins. That is episode 40. Next in the series is episode 41, where we keep building the same contributor muscles.
+**Jamie:** Let's pause on The screen reader-optimized workflow for every inline suggestion. What should a learner take away from it?
 
-</details>
+**Alex:** Anchor this part on The screen reader-optimized workflow for every inline suggestion. This workflow avoids the streaming announcement problem (where suggestions are read out in fragments as tokens arrive) and gives you full, uninterrupted access to the suggestion text before committing. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
 
----
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Type your code or documentation; 2. Copilot generates a suggestion (audio cue sounds if enabled); 3. DO NOT press Tab immediately; 4. Press Alt+F2 - Accessible View opens with the full suggestion text; 5. Read the suggestion at your own pace with Arrow keys. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-### 43. Episode 41: Copilot Billing and Models
+**Jamie:** Let's pause on Step 5: Recommended Workflow for Chat Responses. What should a learner take away from it?
 
-Usage-based billing, GitHub AI Credits, model volatility, and durable model-selection guidance.
+**Alex:** Step 5: Recommended Workflow for Chat Responses has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-Based on: [Appendix K: Copilot Billing and Models](docs/appendix-k-copilot-reference.md)
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Chat: Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs; 2. Type your prompt, press Ctrl+Enter to send; 3. Press Alt+F2 - Accessible View opens immediately; the response streams live into it; 4. Navigate with Arrow keys -. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-Audio and transcript are being regenerated for this episode.
+**Jamie:** Let's pause on Reading the Suggestions Panel (Ctrl+Enter). What should a learner take away from it?
 
-<details>
-<summary>Read Transcript - Episode 41: Copilot Billing and Models</summary>
+**Alex:** Do not treat Reading the Suggestions Panel (Ctrl+Enter) as decoration. Pressing Ctrl+Enter opens a Suggestions Panel - a separate editor tab that shows up to 10 alternative suggestions simultaneously. That is not trivia. This is useful when the default suggestion isn't quite right and you want to compare options.
 
-#### Transcript
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Ctrl+Enter - opens "GitHub Copilot" editor tab; 2. Screen Reader Mode is active: navigate with Browse Mode; 3. H key to navigate headings (each suggestion may be under a heading); 4. Press Alt+F2 on a focused suggestion to read it in Accessible View; 5. Tab to. Read the command, understand what it changes, then run it only when the repository state matches the lesson.

-**Alex:** Welcome back to Git Going with GitHub. This is episode 41: Copilot Billing and Models. I am Alex, and today we are turning Copilot Billing and Models from a list of instructions into a working mental model.
+**Jamie:** Let's pause on Learning Cards: Screen Reader Copilot Workflow. What should a learner take away from it?
 
-**Jamie:** And I am Jamie. I will stop us whenever the instructions sound simple on paper but might feel different with a keyboard and screen reader.
+**Alex:** Learning Cards: Screen Reader Copilot Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
----
+**Alex:** Here is the part to remember. The golden rule: never accept a suggestion with Tab before reviewing it -- press Alt+F2 first, read it, then Ctrl+/ to insert. Enable the four Copilot audio signals (inline suggestion, request sent, response pending, response received) for non-verbal status awareness. Ctrl+Enter opens a Suggestions Panel with up to 10 alternatives -- navigate with H for headings, then Tab to the Accept button. Inline ghost text is typically rendered in a muted color -- if hard to see, rely on the lineHasInlineSuggestion audio signal instead. The Suggestions Panel (Ctrl+Enter) shows alternatives in a full editor tab at your current font size and theme. Chat responses are easier to read in Accessible View than in the streaming panel, especially at high zoom.
 
-**Alex:** Usage-based billing, GitHub AI Credits, model volatility, and durable model-selection guidance. That is the surface description. Underneath it, we are building judgment: where to focus, what to ignore, and how to verify the result.
+**Alex:** Keep the teaching thread moving. Put 13. awesome-copilot - Plugin Ecosystem into plain language. awesome-copilot is a GitHub repository (github/awesome-copilot) - not a VS Code Marketplace extension. The useful version is: It is GitHub's curated ecosystem of Copilot plugins, prompts, instructions, agents, skills, and hooks that can be shared and discovered by anyone. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
-**Jamie:** So we are not using the audio as a shortcut around learning. We are using it to make the learning easier to enter.
+**Jamie:** Let's pause on Repository Structure. What should a learner take away from it?
 
-**Alex:** Yes. A good audio lesson gives someone enough context to try the work with confidence, even before they open the written material.
+**Alex:** The teaching point here is not the label; it is the move. LLM discovery: https://github.github.io/awesome-copilot/llms.txt - a machine-readable index of all available resources.
 
 ---
 
-**Jamie:** Okay, set the room for us. What are we walking into?
-
-**Alex:** Keyboard Shortcuts, Chat, Screen Reader Workflow, Plugin Ecosystem, and GitHub Agentic Workflows: Quick-reference card for GitHub Copilot in VS Code and the broader agentic ecosystem - plugins, MCP servers, and cloud-based automation. The next useful detail is concrete: For the Copilot lesson, see Chapter 16: GitHub Copilot.
+**Jamie:** Let's pause on The /plugin Command - Browse and Install from Chat. What should a learner take away from it?
 
-**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
+**Alex:** This part earns its place because the easiest way to explore awesome-copilot from VS Code.
 
-**Alex:** The next layer is this. Here is the learner-facing version. Word-by-word acceptance (Ctrl+Right Arrow) is recommended for screen reader users - it lets you review the suggestion incrementally before committing to it. Put another way, accessible View workflow for screen reader users: Press Alt+F2 when a suggestion appears to hear the full text without streaming noise, then press Ctrl+/ to insert it directly from the Accessible View without closing the panel first. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Alex:** The path is straightforward once it is named. Step one is open Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette. Step two is type /plugin and press Enter. Step three is Copilot Chat opens an interactive plugin marketplace browser. Step four is browse plugins by category, read descriptions, and install with a single command. If one step does not match what you hear, stop there and re-orient.
 
-**Jamie:** What is the one idea that makes the next few steps less mysterious?
+**Jamie:** Let's pause on CLI Plugin Installation. What should a learner take away from it?
 
-**Alex:** This is the move inside Accessibility: use Accessible View (Alt+F2) every time Copilot responds. That matters in practice: It provides the complete response in a readable pane - no streaming, no live region noise, proper heading structure.
+**Alex:** CLI Plugin Installation: From any terminal with GitHub CLI (gh) installed.
 
-**Jamie:** That feels much more doable when you say it as one move.
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Browse the marketplace; gh copilot plugin marketplace list; Add the awesome-copilot collection; gh copilot plugin marketplace add github/awesome-copilot; Install a specific plugin; gh copilot plugin install @awesome-copilot/accessibility-toolkit; List what you. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+**Jamie:** Let's pause on MCP Server Integration (Docker required). What should a learner take away from it?
 
----
+**Alex:** Here is the learner-facing version. awesome-copilot also ships as an MCP (Model Context Protocol) Server - a Docker-based tool server that extends Copilot with additional capabilities beyond file-based customizations. Put another way, install in VS Code by clicking the button at https://aka.ms/awesome-copilot/mcp/vscode, or add manually to settings.json. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
-**Alex:** Now bring the learner back to the room. Anchor this part on 2. Chat Participants. Type these in the Copilot Chat input to give Copilot context from a specific source.
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like {; "mcp": {; "servers": {; "awesome-copilot": {; "type": "stdio",; "command": "docker",; "args": [; "run", "-i", "--rm",; "ghcr.io/github/awesome-copilot-mcp:latest"; ]; }; }; }; }. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Jamie:** What should they understand before typing anything?
+---
 
-**Alex:** Example prompts has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on 14. GitHub Agentic Workflows and Third-Party Agents. What should a learner take away from it?
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like @workspace find all places where heading hierarchy is documented; @github search community-access/accessibility-agents for issues labeled accessibility; @terminal what did the last command output mean? Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** This is the move inside 14. GitHub Agentic Workflows and Third-Party Agents: status: Technical Preview - GitHub Agentic Workflows entered technical preview on February 13, 2026. That matters in practice: As of May 2026 the feature remains in active development and preview; changes to the API and workflow format are ongoing.
 
-**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+**Alex:** Keep the teaching thread moving. Anchor this part on What This Enables. Browse 50+ community-built workflows at Peli's Agent Factory.
 
-**Alex:** That matters because of the next idea. Do not treat 3. Chat Slash Commands as decoration. Type / in Copilot Chat to see the available built-in commands. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+**Jamie:** Let's pause on How It Works. What should a learner take away from it?
 
-**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+**Alex:** The reason this matters is simple: the gh aw CLI (a gh extension) compiles.md workflow files into.lock.yml GitHub Actions workflows.
 
 ---
 
-**Jamie:** There are a lot of tools in play. How do we keep that from feeling like a contest?
+**Alex:** Keep the teaching thread moving. Do not treat GitHub.com Cloud Agents and Third-Party Agent Assignment as decoration. On GitHub.com, you can assign tasks to different AI agents, including third-party agents from other providers. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
 
-**Alex:** If the interface shifts, Workspace management slash commands is still useful because these are Copilot's built-in chat slash commands. For someone navigating by keyboard or screen reader, this detail matters: Accessibility Agents adds 28 additional workspace-level slash commands from.github/prompts/ - see Appendix L for the full list.
+**Jamie:** Let's pause on Workflow: Assigning Tasks to Cloud Agents on GitHub. What should a learner take away from it?
 
-**Alex:** This is where the talk moves from concept to action. Put 4. Chat Modes into plain language. Select the current mode from the dropdown at the bottom of the Chat input area. The useful version is: The mode selector is in the Chat panel toolbar at the bottom.
+**Alex:** Workflow: Assigning Tasks to Cloud Agents on GitHub has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+**Alex:** Start here: Open an issue or pull request on GitHub.com. Then: Click Assignees in the right panel. Next: Search for the agent name (@copilot, @claude, etc.). Last: Select the agent. Each step should leave a trace you can name.
 
-**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+**Jamie:** Before we leave Workflow: Assigning Tasks to Cloud Agents on GitHub, what is the practical point?
 
-**Jamie:** What stays the same when the tool changes?
+**Alex:** Walk it in order: Add a comment describing the task; The agent reads the issue, makes a plan, creates a branch, implements, and opens a PR; and Review the agent's PR changes before merging. If one step does not match what you hear, stop there and re-orient.
 
-**Alex:** Learning Cards: Chat Participants, Commands, and Modes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. Put Example Scenarios into plain language. Scenario 1: Copilot cloud agent for bug fix. The useful version is: Scenario 2: Claude agent for documentation.
 
-**Alex:** These are the details that keep the idea from floating away. Type @ in Chat to scope context (@workspace, @terminal, @github) -- the autocomplete list is keyboard-navigable with arrow keys. Type / for slash commands (/explain, /fix, /tests) -- each is announced with its description as you arrow through. The mode selector is at the bottom of the Chat panel toolbar; Tab to it, then Space or Enter to open the dropdown. Chat responses appear in the panel with syntax highlighting -- increase the Chat panel font size via editor.fontSize in settings. The @ and / trigger characters are small but the autocomplete popup that follows is large and themed to your current color scheme. Use Ask mode for reading explanations, Agent mode for controlled multi-file changes and autonomous tasks (Edit mode is being deprecated into Agent mode as of VS Code 1.118).
+**Alex:** Here is the part to remember. Assign a GitHub issue to @copilot. Add details about the bug. Copilot creates a branch, reproduces the bug, fixes it, and opens a PR. Assign @claude to improve project docs.
 
 ---
 
-**Alex:** Before the learner moves on. This part earns its place because GitHub Copilot supports multiple ways to provide custom instructions. That gives the learner a foothold: they differ by scope, priority, trigger mechanism, and which tools recognize them. That is the difference between following directions and owning the workflow.
+**Jamie:** Let's pause on Accessibility: Reviewing Agent PRs. What should a learner take away from it?
 
-**Jamie:** What would you say to someone who is already bracing for this to be too much?
+**Alex:** Accessibility: Reviewing Agent PRs has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** 4A. Always-On Instructions -.github/copilot-instructions.md: What it is: The primary VS Code Copilot instruction file. The next useful detail is concrete: Content is automatically included in every chat request and inline suggestion context - you never need to invoke it.
+**Alex:** Here is the part to remember. Agent PRs appear as regular PRs on GitHub.com. Press H to navigate PR headings (Files Changed, Conversation, Checks). Use T to open the file tree and review changes by file. Read through the diff at your own pace; no streaming text. Press G I to jump to the Issue discussion. PR diffs are rendered as text; zoom in for readability.
 
-**Jamie:** How would you walk the room through that step by step?
+**Alex:** Keep the teaching thread moving. This part earns its place because the AI agent (GitHub Copilot, Claude, or OpenAI Codex) reads your repository context and the natural language instructions, then performs the task using the GitHub MCP Server and other available tools. That is the difference between following directions and owning the workflow.
 
-**Alex:** Auto-generate with /init has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. Cloud agents are powerful for real-world workflows, but the workshop focuses on understanding the underlying concepts first. Teach learners to review agent PRs carefully - they're still AI-generated and need human judgment. Show an example: "Here's a PR created by Copilot Cloud. Notice the changes and think about whether they match the original requirements.". Emphasize: Agents are accelerators, not replacements for code review.
+
+**Jamie:** Let's pause on Workflow Format - Markdown with Frontmatter. What should a learner take away from it?
 
-**Alex:** Start here: Open Copilot Chat. Then: Type /init. Next: VS Code analyzes your workspace and generates a tailored copilot-instructions.md. Last: Review and edit the result before committing. If one step does not match what you hear, stop there and re-orient.
+**Alex:** Workflow Format - Markdown with Frontmatter: Unlike standard GitHub Actions (YAML), agentic workflows are Markdown files. The next useful detail is concrete: The body is natural language - describe what you want the AI agent to do.
 
 ---
 
-**Jamie:** How should a learner choose a tool without feeling judged by the choice?
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Workflows run read-only by default with sandboxed execution, network isolation, and SHA-pinned dependencies. Put another way, write operations require explicit declaration in safe-outputs - a set of pre-approved, sanitized GitHub operations.
 
-**Alex:** This is the move inside 4B. Always-On Instructions - AGENTS.md (Multi-Tool / Monorepo): what it is: An open standard instruction file recognized by multiple AI tools - GitHub Copilot, Claude Code, Gemini CLI, and others. That matters in practice: Use this instead of copilot-instructions.md when you want one instruction file that works across all AI coding assistants.
+**Jamie:** Let's pause on Getting Started with gh aw. What should a learner take away from it?
 
-**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
+**Alex:** Getting Started with gh aw has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Install the CLI extension; gh extension install github/gh-aw; Create a new workflow interactively (from github.com or VS Code also works); gh aw create; Compile your Markdown workflow to a GitHub Actions.lock.yml; gh aw. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** Here is the moment where the page starts to make sense. Anchor this part on 4C. Always-On Instructions - CLAUDE.md (Cross-Tool Compatibility). What it is: Instructions file originally from Claude Code that VS Code Copilot also recognizes. This is the part to say slowly: When to use: Mixed AI tool environments where Claude Code and VS Code Copilot are both used. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Jamie:** Let's pause on Monitoring Agentic Workflow Runs. What should a learner take away from it?
 
-**Jamie:** Where do you want a learner to place their attention here?
+**Alex:** Monitoring Agentic Workflow Runs has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The reason this matters is simple: enable/disable: Set chat.useClaudeMdFile: true (default: on). The listener should be able to check this: Claude Rules format (for.claude/rules/ and /.claude/rules/).
+**Alex:** Think of this as 4 checks: Navigate to the Actions tab of your repository (D → Repository navigation → K to Actions); Find the workflow by name (h3 headings, navigate with 3); Press Enter to open a specific run; and Expand job steps to read the agent output log and any safe-outputs created. The point is not speed; the point is never losing your place.
 
 ---
 
-**Alex:** The next point gives the learner a handle. Do not treat 4D. Conditional / Scoped Instructions -.instructions.md as decoration. What it is: Instructions that apply only when specific file types or folders are involved in the chat. That is not trivia. More targeted than always-on instructions.
+**Jamie:** Let's pause on Resources. What should a learner take away from it?
 
-**Jamie:** Give me the version that sounds like an instructor, not a manual.
+**Alex:** The reason this matters is simple: relationship to Accessibility Agents: Accessibility Agents agents (.agent.md files) are designed for interactive use inside VS Code. The listener should be able to check this: GitHub Agentic Workflows are a separate, cloud-native system that uses its own Markdown workflow format and the gh aw CLI - they are complementary tools, not the same mechanism.
 
-**Alex:** Create an instructions file has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. Learning Cards: GitHub Agentic Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** A few details make that real. Ctrl+Shift+P → "Chat: New Instructions File" → choose scope (Workspace or User). Or create the file manually in.github/instructions/.
+**Alex:** Here is the part to remember. Agentic workflow runs appear in the Actions tab of your repository -- navigate to Actions with T (tab bar), then use heading navigation (3) to jump between workflow run entries. Workflow files are Markdown (.md) not YAML -- the frontmatter at the top controls triggers and permissions; the body is natural language instructions the AI agent reads. The safe-outputs frontmatter property lists every write operation the agent is allowed to perform -- review this section carefully since it is the security boundary. The Actions tab lists workflow runs with status icons (green check, red X, yellow circle) -- at high zoom, also look for the text status label next to each run name. Workflow.md files use the same Markdown rendering as any other file in the repo -- edit them in VS Code with your preferred font size and theme. The gh aw compile command generates a.lock.yml file alongside your.md file -- both appear in the file explorer; the.lock.yml is auto-generated and should not be edited manually.
 
-**Alex:** Hold that next to this. Put 4E. Organization-Level Instructions (GitHub Enterprise and Teams) into plain language. What it is: Organization administrators define custom instructions that apply to all repositories in the organization. The useful version is: Every team member automatically gets these instructions added to their Copilot context. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Jamie:** Let's pause on Copilot Models. What should a learner take away from it?
 
-**Jamie:** So the learner is not behind if they stop there and check the page.
+**Alex:** Copilot Models has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Yes. Pausing to verify is not a detour; it is how you keep control of the workflow.
+**Alex:** Here is the part to remember. Overview. How to Choose a Model. Current Model and Billing Sources. Model Availability by Plan. GitHub AI Credits and Usage. Switching Models in VS Code.
 
 ---
 
-**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
-
-**Alex:** The teaching point here is not the label; it is the move. Use for: Organization-wide coding standards, security policies, legal disclaimers (open source license obligations), toolchain conventions.
+**Alex:** Keep the teaching thread moving. Put 1. Overview into plain language. GitHub Copilot offers access to AI models from multiple providers including OpenAI, Anthropic, Google, and others. The useful version is: The model you choose affects response quality, speed, and usage cost. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
-**Alex:** That shows up in the workshop in a few specific ways. GitHub Enterprise or Teams plan with Copilot enabled. Admin configures instructions in organization settings on GitHub.com. Each user must enable discovery in VS Code.
+**Jamie:** Let's pause on 2. How to Choose a Model. What should a learner take away from it?
 
-**Alex:** That connects to another useful point. This part earns its place because these settings-based instructions are deprecated and may be removed in a future VS Code release. That gives the learner a foothold: for new work, use copilot-instructions.md or.instructions.md files.
+**Alex:** The teaching point here is not the label; it is the move. GitHub Docs organizes models by task. That is the difference between guessing and knowing: Match your task to the right level of capability instead of memorizing a model name.
 
-**Jamie:** How should someone choose between those options?
+**Alex:** Keep the teaching thread moving. This part earns its place because use the default or Auto selection for short explanations, Markdown drafting, commit messages, PR descriptions, and small refactors. That gives the learner a foothold: for this workshop, this is the safest starting point.
 
-**Alex:** 4G. Comparison - When to Use Each Approach has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+---
 
-**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Approach means Always-on? means Multi-tool? means Best. copilot-instructions.md means Workspace means VS Code only means Primary project instructions. AGENTS.md means Workspace + monorepo means All AI tools means Multi-tool teams or large monorepos.
+**Jamie:** What do you want them to do when the plan breaks?
 
----
+**Alex:** Fast help with simple or repetitive tasks: Use lighter models for quick answers, boilerplate, simple rewrites, and short command explanations. The next useful detail is concrete: This helps preserve included usage when billing is usage-based.
 
-**Alex:** Here is the practical turn. Learning Cards: Custom Instructions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Use more capable models for architecture questions, unfamiliar codebases, multi-file reasoning, and difficult debugging. Put another way, these interactions typically consume more usage because they process more context and generate longer responses. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
-**Alex:** On the ground, that means a few things. The three-level scope hierarchy (Organization, Workspace, User) means instructions can come from multiple places -- use Chat Diagnostics (gear icon in Chat header) to list every loaded instruction file and its source.github/copilot-instructions.md is always-on and requires no frontmatter -- just write plain Markdown; screen readers read the source file like any other Markdown document.instructions.md files use YAML frontmatter with applyTo globs -- the frontmatter is the first few lines between --- delimiters; arrow through carefully to verify syntax. The Diagnostics panel (Chat gear, then Diagnostics) lists loaded files in a scrollable pane -- increase font size in VS Code settings if the file paths are hard to read. YAML frontmatter is indentation-sensitive -- enable VS Code's indentation guides (editor.guides.indentation) and use a high-contrast theme so the guide lines are visible. The /init command auto-generates copilot-instructions.md from your workspace -- review the generated file in your editor at your preferred zoom before committing.
+**Jamie:** Let's pause on Agentic software development. What should a learner take away from it?
 
-**Jamie:** Let's pause on 6. Accessible View Workflow. What should a learner take away from it?
+**Alex:** This is the move inside Agentic software development: agent mode, Copilot CLI, Copilot cloud agent, and third-party coding agents can make multiple model calls within one task. That matters in practice: Use them for scoped, valuable work rather than casual exploration, especially when working under a limited plan.
 
-**Alex:** This is the move inside 6. Accessible View Workflow: Copilot Chat responses stream in token by token, which can fragment screen reader announcements. That matters in practice: Accessible View (Alt+F2) gives you a complete, static, properly structured version of the response.
+---
 
-**Jamie:** That is a useful checkpoint before anyone starts pressing keys.
+**Alex:** Keep the teaching thread moving. Anchor this part on Working with visuals. Check the model picker and the official supported-models documentation before planning an exercise that depends on screenshots or image analysis.
 
-**Alex:** Exactly. Checkpoints turn uncertainty into information.
+**Jamie:** Let's pause on 3. Current Model and Billing Sources. What should a learner take away from it?
 
-**Jamie:** What should happen before anyone copies and runs it?
+**Alex:** The reason this matters is simple: the following table lists the official sources to use instead of static model tables in this curriculum.
 
-**Alex:** Anchor this part on Recommended Workflow - Every Copilot Interaction. VS Code December 2025: The Accessible View now streams dynamically. This is the part to say slowly: You can open it immediately after sending a prompt and follow the response as it arrives - no need to wait for the response to finish before pressing Alt+F2.
+**Alex:** Keep the teaching thread moving. Source-backed facts verified May 12, 2026 has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Copilot Chat: Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs; 2. Type your prompt; 3. Press Ctrl+Enter to send; 4. Press Alt+F2 to open Accessible View (open immediately - no need to wait); 5. Follow as the response. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** Here is the part to remember. GitHub Copilot moves to usage-based billing on June 1, 2026. Premium request units are being replaced by GitHub AI Credits. One GitHub AI Credit equals $0.01 USD in the usage-based billing documentation. Copilot Chat, Copilot CLI, Copilot cloud agent, Copilot Spaces, Spark, and third-party coding agents consume AI Credits. Code completions and next edit suggestions are not billed in AI Credits for paid plans. Copilot code review is expected to consume GitHub Actions minutes in addition to GitHub AI Credits starting June 1, 2026.
 
 ---
 
-**Jamie:** Let's pause on NVDA / JAWS. What should a learner take away from it?
+**Jamie:** Let's pause on 4. Model Availability by Plan. What should a learner take away from it?
 
-**Alex:** NVDA / JAWS has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** If the interface shifts, 4. Model Availability by Plan is still useful because plan names, included usage, and model access can change by date, account type, organization policy, region, and rollout. For someone navigating by keyboard or screen reader, this detail matters: Do not copy plan limits from this appendix into learner instructions.
 
-**Alex:** That becomes easier when you listen for these cues. Up/Down Arrow - read line by line. Ctrl+Home - jump to start. H - navigate by headings (if response has sections). Escape - close Accessible View, return to Chat.
+**Alex:** Keep the teaching thread moving. Put Workshop-safe plan guidance into plain language. Check GitHub Copilot settings for your account and the GitHub Copilot plans page for current public plan details.
 
-**Alex:** Another way to ground it. VoiceOver has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. Copilot Free can support short, focused workshop prompts, but it has monthly limits. Verified students may have access to GitHub Copilot Student plan benefits. Organization and enterprise users may have Copilot access managed by an administrator. Paid plans include more usage and broader feature access, but the billing unit changes to GitHub AI Credits on June 1, 2026. Annual individual plans may follow transition rules that differ from monthly plans.
 
-**Alex:** If someone is taking notes, this is the short list. VO+Shift+Down - interact with the Accessible View content. Down Arrow - read line by line. VO+Escape - stop interacting. Escape - close Accessible View.
+**Jamie:** Let's pause on 5. GitHub AI Credits and Usage. What should a learner take away from it?
 
-**Jamie:** What is the safe way to learn from that example?
+**Alex:** The teaching point here is not the label; it is the move. Usage-based billing measures Copilot usage with GitHub AI Credits. That is the difference between guessing and knowing: The cost of an interaction depends on the selected model and the tokens used for input, output, and cached context.
 
-**Alex:** If the interface shifts, Accessible View for Inline Suggestions is still useful because when a multi-line ghost text suggestion appears in the editor. For someone navigating by keyboard or screen reader, this detail matters: This is especially important for multi-line suggestions where ghost text is hard to review incrementally.
+---
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Do not accept immediately; 2. Press Alt+F2; 3. Accessible View shows: "Suggestion: [full text]"; 4. Read the complete suggestion at your own pace; 5. Press Escape to close; 6. Press Tab to accept, or Escape to reject. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** Keep the teaching thread moving. Tips for managing usage has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
----
+**Alex:** Here is the part to remember. Use Auto model selection unless the facilitator gives a specific reason to choose a model. Keep workshop prompts focused and short. Ask one clear question at a time when using Copilot Free or any limited plan. Use agentic features for meaningful multi-step tasks, not casual exploration. Review model badges, model picker details, and usage dashboards when they are available in your account. Prefer code completions and next edit suggestions for simple local edits because paid-plan documentation says those are not billed in AI Credits.
 
-**Alex:** This is the part worth saying out loud. Accessible View for Code Blocks has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on In the Chat Panel. What should a learner take away from it?
 
-**Alex:** Here is the part that makes the next action easier. Code blocks appear inside elements in Accessible View. Screen readers announce "code block" or "pre-formatted text" at the start. Each line is on its own line (not run together). Indentation is preserved.
+**Alex:** In the Chat Panel has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** I like that because it gives people permission to slow down.
+**Alex:** First, open the Chat panel (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette. Then, at the bottom of the chat input area, you'll see the current model name as a button, often Auto or a specific model name. After that, activate the model picker button - this opens a dropdown list of available models. Finally, arrow through the list and press Enter to select a model. Each step should leave a trace you can name.
 
-**Alex:** That is the goal. We want the page to feel explorable, not fragile.
+**Jamie:** Before we leave In the Chat Panel, what is the practical point?
 
-**Jamie:** Let's pause on Learning Cards: Accessible View Workflow. What should a learner take away from it?
+**Alex:** Start here: For screen reader users: the chat input will announce the newly selected model after switching. If one step does not match what you hear, stop there and re-orient.
 
-**Alex:** Learning Cards: Accessible View Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on In an Inline Chat Session. What should a learner take away from it?
 
-**Alex:** These are the pieces that turn the idea into a usable move. Press Alt+F2 immediately after sending a prompt -- Accessible View now streams dynamically so you can follow along in real time. Navigate Chat responses with Up/Down Arrow; headings, code blocks, and lists are structurally intact in the view. For inline suggestions, press Alt+F2 to read the full ghost text, then Ctrl+/ to insert it directly from the Accessible View. Accessible View renders Chat responses as a static, scrollable pane -- easier to read at high zoom than the streaming Chat panel. Code blocks in Accessible View preserve indentation and syntax -- pair with a high-contrast theme for maximum readability. Ctrl+Home jumps to the start of the response; Ctrl+End to the end -- useful for long multi-section outputs.
+**Alex:** In an Inline Chat Session has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Put that beside the next piece. This part earns its place because every Copilot customization file lives at one of three scopes. That gives the learner a foothold: VS Code combines all matching files from all scopes - it is additive, not winner-takes-all. That is the difference between following directions and owning the workflow.
+**Alex:** Start here: Open Inline Chat (Ctrl+I / Cmd+I). Then: The model picker appears in the inline chat toolbar. Next: Same interaction: activate the model button to switch. If one step does not match what you hear, stop there and re-orient.
 
 ---
 
-**Jamie:** Let's pause on Workspace (Repository) - Team-Shared. What should a learner take away from it?
+**Jamie:** Let's pause on Keyboard Note for Screen Readers. What should a learner take away from it?
 
-**Alex:** Workspace (Repository) - Team-Shared: Files committed to your repository. The next useful detail is concrete: Everyone who clones the repo gets them.
+**Alex:** This is the move inside Keyboard Note for Screen Readers: in the Chat panel, the model picker button is near the bottom of the chat view. That matters in practice: If you're having trouble locating it.
 
-**Alex:** Now shift from knowing the term to using it. Here is the learner-facing version. Files in your VS Code profile folder. Put another way, available in every workspace you open.
+**Alex:** Here is the part to remember. Tab through the bottom toolbar of the chat panel. Listen for the model name announced - it appears between the "Attach" button and the send button. Press Space or Enter to open the picker.
 
-**Jamie:** Let's pause on Organization - GitHub-Configured (Enterprise/Teams). What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Anchor this part on 7. Auto Model Selection. Auto mode lets Copilot choose the best model based on the type of request. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
 
-**Alex:** This is the move inside Organization - GitHub-Configured (Enterprise/Teams): configured by administrators in GitHub organization settings. That matters in practice: Automatically applied to all organization members.
+**Jamie:** Let's pause on How Auto works. What should a learner take away from it?
+
+**Alex:** How Auto works has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. For simple questions, Copilot routes to a faster, lighter model. For complex code generation or debugging, Copilot upgrades to a more capable model automatically. For agent tasks, Copilot selects an appropriate Codex model. You may be able to see which model was used after each response. VS Code 1.119 and later can show model details and multipliers for some Copilot CLI and agent responses.
+
+---
+
+**Alex:** Keep the teaching thread moving. Do not treat When to override Auto as decoration. To switch back to Auto from a specific model, re-open the model picker and select Auto at the top of the list.
+
+**Alex:** Here is the part to remember. You specifically need a model with certain capabilities, such as image input. You're managing usage and want to control costs. You've found a particular model gives better results for your specific workflow or domain. You're doing agentic work and want to explicitly select an agent-optimized Codex model (check current availability in the model picker).
+
+**Jamie:** Let's pause on 8. Models Retiring Soon. What should a learner take away from it?
+
+**Alex:** If the interface shifts, 8. Models Retiring Soon is still useful because GitHub regularly updates the model roster. For someone navigating by keyboard or screen reader, this detail matters: Older model versions are retired when newer equivalents are available.
+
+**Alex:** Keep the teaching thread moving. Put Recent retirement signals into plain language. The April-May 2026 GitHub Copilot changelog included retirements and deprecations for several model families. The useful version is: Treat any named model in workshop materials as a temporary example, not a guarantee. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+
+---
+
+**Jamie:** Let's pause on 15. Copilot Pricing, Free Plan, and Usage Limits. What should a learner take away from it?
+
+**Alex:** The teaching point here is not the label; it is the move. GitHub Copilot moved to usage-based billing on June 1, 2026. That is the difference between guessing and knowing: Premium request units were replaced by GitHub AI Credits.
+
+**Alex:** Keep the teaching thread moving. This part earns its place because source: GitHub Copilot Plans (updated May 2026).
+
+**Jamie:** Zoom out for a second. What kind of journey is this?
+
+**Alex:** Free Plan Details and Workshop Considerations: Copilot Free is a zero-cost plan with limited monthly usage. The next useful detail is concrete: It's suitable for learning, but facilitators should be aware of the constraints.
+
+---
+
+**Alex:** Keep the teaching thread moving. Free Plan Restrictions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. No agent support: If your workshop uses agents (e.g., @web-accessibility-wizard), Free plan users cannot participate in those exercises. Chat limits can be reached quickly: 2K tokens is roughly 3-5 multi-turn chat conversations depending on context size. No Copilot CLI: Free plan users cannot use the Copilot CLI for command-line assistance. No Copilot Cloud: Cannot run cloud-based agentic workflows. Resets monthly: Limits reset at the start of each month.
+
+**Jamie:** Let's pause on Workshop Guidance for Free Plan Users. What should a learner take away from it?
+
+**Alex:** This is the move inside Workshop Guidance for Free Plan Users: if your workshop has Free plan participants.
+
+**Alex:** Walk it in order: Pre-workshop communication: Explain the limits and suggest they upgrade temporarily for paid plans' benefits; Task design: Use short, focused prompts that consume fewer tokens; Alternative: Education benefits: Verified students may be eligible for GitHub Education benefits including free Copilot Pro; and Time management: Encourage learners to plan their chat questions before asking to avoid wasted tokens. The sequence works because every action has a confirmation.
+
+**Jamie:** Before we leave Workshop Guidance for Free Plan Users, what is the practical point?
+
+**Alex:** Think of this as 1 checks: Completion workflow: Teach local inline suggestions first (ghost text), then introduce Chat later to preserve the monthly limit. Keep it that plain: know where you are, make the move, check the result.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on Copilot Pro Comparison: When to Recommend an Upgrade. Recommend Copilot Pro ($10/month) for workshops if. This is the part to say slowly: Many learners find the $10/month cost is worthwhile to remove friction during intensive learning.
+
+**Alex:** Here is the part to remember. Your exercises involve Copilot Chat extensively. You want learners to experiment freely without token anxiety. The workshop lasts multiple days (Free plan limits reset monthly, but daily resets don't exist). You use custom instructions or multiple models.
+
+---
+
+**Jamie:** Let's pause on Usage-Based Billing and GitHub AI Credits (Post June 1, 2026). What should a learner take away from it?
+
+**Alex:** The reason this matters is simple: on June 1, 2026, GitHub Copilot switched from Premium Request Units (PRUs) to GitHub AI Credits.
+
+**Alex:** Keep the teaching thread moving. Credit Pricing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. 1 GitHub AI Credit = $0.01 USD. Costs vary by model and input/output token consumption. Cached context may receive discounts. Code completions (ghost text) remain free for paid plans.
+
+**Jamie:** Let's pause on Managing Usage. What should a learner take away from it?
+
+**Alex:** If the interface shifts, Managing Usage is still useful because users see their credit consumption in GitHub Settings - Copilot under Usage & Billing.
+
+**Alex:** Here is the part to remember. Advise learners to monitor their usage if they're on a limited plan. Set expectations: "A typical multi-turn chat conversation costs 5-50 credits depending on the model". Recommend Auto model selection to balance quality and cost. Mention monthly resets if learners are concerned about billing.
+
+---
+
+**Alex:** Keep the teaching thread moving. Keyboard & Accessibility Notes for Checking Plans has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Visit GitHub Copilot Plans and use H to navigate plan headings. Plan names are announced as headings. Feature lists are unordered lists; navigate with L. Use T to navigate pricing tables; arrow keys move between cells. Pricing is typically in the leftmost column of each table. Plan pricing page uses clear, high-contrast pricing tables.
+
+**Jamie:** Let's pause on Related Resources. What should a learner take away from it?
+
+**Alex:** Related Resources has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. GitHub Copilot Plans. GitHub Copilot Documentation. Usage-based Billing for Individuals. GitHub Copilot Changelog.
+
+**Alex:** Keep the teaching thread moving. This part earns its place because next: Appendix L: Agents Reference Back: Appendix J: Codespaces Teaching chapter: Chapter 16: GitHub Copilot. That is the difference between following directions and owning the workflow.
+
+---
+
+**Jamie:** What should people carry with them after this?
+
+**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+
+**Jamie:** That is a better way to say it than just follow the steps.
+
+**Alex:** Right. Steps matter, but understanding wins. Keep the next learning block nearby, because each part of the series keeps building the same contributor muscles.

+
+#### Transcript
+
+**Alex:** Welcome back to Git Going with GitHub. This is Copilot Billing and Models. I am Alex, and today we are turning Copilot Billing and Models from a list of instructions into a working mental model.
+
+**Jamie:** And I am Jamie. I will stop us whenever the instructions sound simple on paper but might feel different with a keyboard and screen reader.
+
+---
+
+**Alex:** Usage-based billing, GitHub AI Credits, model volatility, and durable model-selection guidance. That is the surface description. Underneath it, we are building judgment: where to focus, what to ignore, and how to verify the result.
+
+**Jamie:** So we are not using the audio as a shortcut around learning. We are using it to make the learning easier to enter.
+
+**Alex:** Yes. A good audio lesson gives someone enough context to try the work with confidence, even before they open the written material.
+
+---
+
+**Jamie:** Okay, set the room for us. What are we walking into?
+
+**Alex:** Keyboard Shortcuts, Chat, Screen Reader Workflow, Plugin Ecosystem, and GitHub Agentic Workflows: Quick-reference card for GitHub Copilot in VS Code and the broader agentic ecosystem - plugins, MCP servers, and cloud-based automation. The next useful detail is concrete: For the Copilot lesson, see Chapter 16: GitHub Copilot.
+
+**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
+
+**Alex:** The next layer is this. Here is the learner-facing version. Word-by-word acceptance (Ctrl+Right Arrow) is recommended for screen reader users - it lets you review the suggestion incrementally before committing to it. Put another way, accessible View workflow for screen reader users: Press Alt+F2 when a suggestion appears to hear the full text without streaming noise, then press Ctrl+/ to insert it directly from the Accessible View without closing the panel first. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
+
+**Alex:** This is the move inside Accessibility: use Accessible View (Alt+F2) every time Copilot responds. That matters in practice: It provides the complete response in a readable pane - no streaming, no live region noise, proper heading structure.
+
+**Jamie:** That feels much more doable when you say it as one move.
+
+**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+
+---
+
+**Alex:** Now bring the learner back to the room. Anchor this part on 2. Chat Participants. Type these in the Copilot Chat input to give Copilot context from a specific source.
+
+**Jamie:** What should they understand before typing anything?
+
+**Alex:** Example prompts has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like @workspace find all places where heading hierarchy is documented; @github search community-access/accessibility-agents for issues labeled accessibility; @terminal what did the last command output mean? Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+
+**Alex:** That matters because of the next idea. Do not treat 3. Chat Slash Commands as decoration. Type / in Copilot Chat to see the available built-in commands. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+
+---
+
+**Jamie:** There are a lot of tools in play. How do we keep that from feeling like a contest?
+
+**Alex:** If the interface shifts, Workspace management slash commands is still useful because these are Copilot's built-in chat slash commands. For someone navigating by keyboard or screen reader, this detail matters: Accessibility Agents adds 28 additional workspace-level slash commands from.github/prompts/ - see Appendix L for the full list.
+
+**Alex:** This is where the talk moves from concept to action. Put 4. Chat Modes into plain language. Select the current mode from the dropdown at the bottom of the Chat input area. The useful version is: The mode selector is in the Chat panel toolbar at the bottom.
 
-**Alex:** Here are the anchors worth keeping. Enable discovery: github.copilot.chat.organizationInstructions.enabled: true. Lowest priority - workspace and user instructions override when there is a conflict.
+**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+
+**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+
+**Jamie:** What stays the same when the tool changes?
+
+**Alex:** Learning Cards: Chat Participants, Commands, and Modes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** These are the details that keep the idea from floating away. Type @ in Chat to scope context (@workspace, @terminal, @github) -- the autocomplete list is keyboard-navigable with arrow keys. Type / for slash commands (/explain, /fix, /tests) -- each is announced with its description as you arrow through. The mode selector is at the bottom of the Chat panel toolbar; Tab to it, then Space or Enter to open the dropdown. Chat responses appear in the panel with syntax highlighting -- increase the Chat panel font size via editor.fontSize in settings. The @ and / trigger characters are small but the autocomplete popup that follows is large and themed to your current color scheme. Use Ask mode for reading explanations, Agent mode for controlled multi-file changes and autonomous tasks (Edit mode is being deprecated into Agent mode as of VS Code 1.118).
+
+---
+
+**Alex:** Before the learner moves on. This part earns its place because VS Code 1.120 introduces the Agents window (Preview, now Stable) for agent-first workflows. That is the difference between following directions and owning the workflow.
+
+**Alex:** That becomes easier when you listen for these cues. Orchestrate tasks across multiple projects and workspaces. Track, review, and manage agent sessions (Copilot CLI, Copilot Cloud, Claude). Access a Customizations panel for agent personas, skills, hooks, MCP servers, and plugins. Use an integrated browser and terminal for validating agent changes. Start sessions on remote machines (SSH, dev tunnel). Create sub-sessions for parallel tasks in the same workspace.
+
+**Jamie:** Give me the sequence, because order matters here.
+
+**Alex:** How to Open the Agents Window has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** First, select Open in Agents from the VS Code title bar. Then, open the Command Palette and run Chat: Open Agents Window. After that, run code --agents from a terminal. Each step should leave a trace you can name.
+
+**Jamie:** How would you walk the room through that step by step?
+
+**Alex:** Safe Review Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Start here: Open the Agents window. Then: Start a new session (Ctrl+N). Next: Choose workspace/repo, trust folder if prompted. Last: Select agent type (Copilot CLI, Cloud, Claude). If one step does not match what you hear, stop there and re-orient.
+
+**Jamie:** What does the learner do first, second, and then after that?
+
+**Alex:** Walk it in order: Prefer worktree isolation for Git projects (keeps agent edits separate until review); Use Files panel sync before agent starts to pull upstream changes; Type a clear, single task; and Review all changes in the Changes panel before accepting. That is the rhythm: orient, act, verify, continue.
+
+---
+
+**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
+
+**Alex:** Accessibility and Inclusion has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** These are the pieces that turn the idea into a usable move. Accessible View: Press Alt+F2 for screen reader-friendly suggestion review and insertion. Keyboard navigation: All panels and controls are keyboard accessible. Screen reader/low vision/sighted workflows: See learning cards below for detailed guidance. Markdown diff preview: Use for documentation changes; supports smart selection and HTML id validation.
+
+**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
+
+**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
+
+**Alex:** Here is the moment where the page starts to make sense. Learning Cards: Agents Window has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Listen for the small confirmations in this list. Open the Agents window from the Command Palette (Chat: Open Agents Window). Use Alt+F1 for Accessibility Help, F6/Shift+F6 to move between areas. Use F7/Shift+F7 for diff navigation, Alt+F2 for Accessible View. Listen for approval prompts before terminal commands. Prefer worktree isolation for safe review. Increase zoom (Ctrl+=), use high-contrast theme (Ctrl+K Ctrl+T).
+
+**Jamie:** Where do you want a learner to place their attention here?
+
+**Alex:** Settings and Limitations has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The useful version is not abstract; it sounds like this. Agents window is Preview in 1.120; not all agent types/extensions supported. Multi-root sessions not yet supported. Some extensions require opt-in. Agent cannot directly open integrated browser (use localhost link or command). Org policy may restrict agents/cloud/model choices.
+
+---
+
+**Alex:** The next point gives the learner a handle. Do not treat Placement in the Workshop as decoration. Introduce the Agents window after learners complete Chat and Agent mode in Chapter 16. That is not trivia. Use it as an advanced review and orchestration surface, not a replacement for learning Git, diffs, PRs, and manual accessibility review.
+
+**Jamie:** What should someone listen for when a lesson offers more than one tool path?
+
+**Alex:** If the interface shifts, Other VS Code 1.120 Changes Worth Calling Out is still useful because the following VS Code 1.120 release-note items are most relevant to this workshop.
+
+**Alex:** Hold that next to this. Put Recommended Settings to Know into plain language. The following table lists settings that matter for this 1.120 update. The useful version is: Example Markdown preview diff setting. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+
+**Jamie:** So the learner is not behind if they stop there and check the page.
+
+**Alex:** Yes. Pausing to verify is not a detour; it is how you keep control of the workflow.
+
+---
+
+**Jamie:** What would you say to someone who is already bracing for this to be too much?
+
+**Alex:** Limitations to Teach Explicitly has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** That shows up in the workshop in a few specific ways. The Agents window is still a Preview feature in VS Code 1.120. Not every agent type or third-party agent is supported in the Agents window yet. Multi-root sessions are not supported in the Agents window yet. Some extensions work automatically, but extension support is still evolving. The agent cannot directly open the integrated browser for you; use a localhost link or Browser: Open Integrated Browser. Organization policy can disable or limit agents, cloud agents, model choices, approvals, and BYOK features.
+
+**Alex:** That connects to another useful point. This part earns its place because introduce the Agents window after learners complete the normal Chat and Agent mode flow in Chapter 16. That gives the learner a foothold: treat it as an advanced navigation and review surface, not a replacement for learning Git, diffs, pull requests, and manual accessibility review.
+
+**Jamie:** What is the common workflow underneath the different interfaces?
+
+**Alex:** 4B. MCP Servers - Accessibility Scanning Tools: Model Context Protocol (MCP) servers expose accessibility scanning tools that work with any MCP-compatible client - VS Code, Claude Desktop, other MCP-aware tools, and CI/CD pipelines.
+
+---
+
+**Alex:** Here is the practical turn. Here is the learner-facing version. MCP is an open protocol (anthropic/model-context-protocol) that lets AI agents access tools and data sources through a standardized interface. Put another way, the Accessibility Agents project operates an HTTP-based MCP server with 30+ accessibility tools - no installation needed, just connect and scan. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Alex:** On the ground, that means a few things. Use the same tools across different AI platforms (Copilot, Claude, Gemini, CI/CD). Tools work offline or in restricted environments via local HTTP server. Streaming responses with live progress updates. Compliance audit history and trending.
+
+**Jamie:** How do we make tool choice feel like access, not pressure?
+
+**Alex:** This is the move inside Core 30+ MCP Tools Catalog: web Accessibility Scanning (8 tools). That matters in practice: Document Accessibility Scanning (10 tools).
+
+**Alex:** Here is what that changes in practice. scan-page - Scan a live URL with axe-core WCAG 2.2 AA rules. scan-pages - Batch scan multiple URLs. scan-dom - Scan raw HTML/DOM without loading a page. scan-with-lighthouse - Lighthouse accessibility audit.
+
+**Jamie:** That is a useful checkpoint before anyone starts pressing keys.
+
+**Alex:** Exactly. Checkpoints turn uncertainty into information.
+
+**Jamie:** What should happen before anyone copies and runs it?
+
+**Alex:** Anchor this part on How to Use MCP Tools in VS Code. Option 1: Via Copilot Chat (direct). This is the part to say slowly: Copilot will recognize "scan-page" and invoke it through the MCP server.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like {; "modelContext.servers": {; "accessibility-agents": {; "command": "node",; "args": ["path/to/mcp-server/index.js"],; "env": {; "PORT": "3000"; }; }; }; }. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+---
+
+**Jamie:** How should a learner choose a tool without feeling judged by the choice?
+
+**Alex:** The reason this matters is simple: use MCP tools in GitHub Actions to run accessibility scans on every commit.
+
+**Alex:** Another way to ground it. Learning Cards: MCP Servers has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** If someone is taking notes, this is the short list. MCP servers work with any MCP client, including VS Code and Claude Desktop -- they expose tools through a standardized interface. The 30+ accessibility tools are named predictably: scan- for audits, export- for reporting, generate- for compliance. MCP tool responses appear in Copilot Chat like any agent output -- press Alt+F2 to read in Accessible View. MCP tools return structured JSON that Copilot renders as Markdown tables and lists -- zoom affects rendering the same as other Chat output. The export-findings-csv tool produces download links; use Ctrl+S to save CSV to your downloads folder. Generate reports with generate-audit-report for complete details; CSV export is for data analysis and trending.
+
+**Jamie:** Give me the version that sounds like an instructor, not a manual.
+
+**Alex:** References has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part that makes the next action easier. Model Context Protocol (MCP) Specification. Anthropic MCP GitHub. Accessibility Agents MCP Server Documentation.
+
+---
+
+**Alex:** This is the part worth saying out loud. Put 4C. Smart Actions into plain language. Smart Actions are predefined AI-powered actions for common coding tasks. The useful version is: They appear as options when you click on code, errors, or use the lightbulb menu.
+
+**Jamie:** I like that because it gives people permission to slow down.
+
+**Alex:** That is the goal. We want the page to feel explorable, not fragile.
+
+**Jamie:** Turn that into a path someone can follow.
+
+**Alex:** How to Trigger Smart Actions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Think of this as 4 checks: Lightbulb menu: Click the lightbulb icon in the left margin of the editor (or press Ctrl+.); Git integration: Stage changes with git add; the commit panel offers "Generate Commit Message"; Error squiggles: Hover over an error and press Ctrl+. to see fixes; and Keyboard shortcut: Ctrl+. opens available actions for the current selection. That is the rhythm: orient, act, verify, continue.
+
+**Alex:** Put that beside the next piece. Screen Reader & Low Vision Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** This is where the lesson becomes something you can check. When the lightbulb appears, VS Code announces it as a clickable action. Press Ctrl+. to open the actions list; it becomes a dropdown menu navigable with arrow keys. Each action is announced with a short description (e.g., "Generate Commit Message"). Press Enter to activate the selected action. Results appear as code suggestions or inline edits that you can review before accepting. The lightbulb icon is visible in the left margin when actions are available.
+
+---
+
+**Jamie:** How should they picture the shape of the workshop?
+
+**Alex:** Workshop Guidance: Introduce Smart Actions as a shortcut for common tasks, but emphasize manual understanding first.
+
+**Alex:** A few details make that real. Teach learners to rename variables manually before showing "Rename Symbol". Teach error-fixing patterns before showing "Fix Error". Use "Generate Commit Message" as a review tool, not a replacement for writing meaningful messages.
+
+**Alex:** Now shift from knowing the term to using it. Here is the learner-facing version. Browser Agent (Experimental) lets your Copilot agent test and validate web applications directly. Put another way, the agent can open your app in the integrated browser, verify features, check for layout issues, and take screenshots.
+
+**Jamie:** Let's pause on What the Browser Agent Can Do. What should a learner take away from it?
+
+**Alex:** What the Browser Agent Can Do has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here are the anchors worth keeping. Open a web app (local or remote) in the integrated browser. Verify that a feature works as expected. Check for layout or visual issues. Take screenshots for documentation. Navigate forms and test user flows. Report accessibility or functionality issues.
 
 **Jamie:** That is the part I would want someone to say out loud while they work.

-**Alex:** This is where confidence starts to build. Anchor this part on 8. Instruction Priority and Conflicts. When multiple instruction sources give conflicting guidance, VS Code uses this priority order. This is the part to say slowly: This priority applies to conflicts. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Jamie:** What is the ordered workflow?
+
+**Alex:** How to Use Browser Agent has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Think of this as 4 checks: Start a Copilot agent session (Chat or Agents window); Ask the agent to test your web app; The agent opens the integrated browser automatically; and It interacts with the page and reports findings. The point is not speed; the point is never losing your place.
+
+**Jamie:** Let's pause on How to Use Browser Agent. What should a learner take away from it?
+
+**Alex:** The path is straightforward once it is named. Step one is review results in Chat and take action as needed. Each step should leave a trace you can name.
 
-**Jamie:** Let's pause on How Instructions Are Combined. What should a learner take away from it?
+**Jamie:** What is the safe way to learn from that example?
 
-**Alex:** The reason this matters is simple: result: Copilot follows TypeScript strict mode (from workspace), British English (from org), AND the Z-spelling override (from user, which overrides the org instruction on that specific point).
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open http://localhost:3000 and take a screenshot of the homepage.; Test the search form at localhost:8080 - enter "accessibility" and verify results appear.; Check the mobile layout of localhost:3000 at 320px width and report any overlapping text.; Verify the. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** For a learner, the useful signals are concrete. Organization: "Use British English spellings". Workspace: "Use TypeScript strict mode". User: "Use British English spellings - but use Z spellings (organize, not organise) for technical terms".
+**Alex:** Keep the thread going. Important: Browser Agent is Experimental has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Keep the thread going. Do not treat Priority Within the Same Scope as decoration. Within a single scope (e.g., workspace), all matching instructions files are combined with no inherent priority. That is not trivia. If two workspace-level.instructions.md files contradict each other, the behavior is undefined - avoid conflicting workspace instructions.
+**Alex:** For a learner, the useful signals are concrete. Feature availability may change. Not all browsers or endpoints are supported. Use only with development servers you control. Results may require human verification. Do not rely on Browser Agent alone for accessibility or security testing.
 
 ---
 
-**Jamie:** Let's pause on Create any new customization file. What should a learner take away from it?
+**Jamie:** Let's pause on Accessibility & Testing Considerations. What should a learner take away from it?
+
+**Alex:** Accessibility & Testing Considerations has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** If the interface shifts, Create any new customization file is still useful because ctrl+Shift+P → "Chat: New Instructions File" (or "New Prompt File", "New Agent File").
+**Alex:** The parts worth keeping in working memory are these. Browser Agent interactions are reported in Copilot Chat as text descriptions. Press Alt+F2 to read the full response in Accessible View. Screenshots taken by the agent appear as images in Chat (not screen-reader friendly). Request text descriptions instead: "Describe what you see on the page instead of taking a screenshot". Browser Agent can zoom the test environment independently of your VS Code zoom. Request large screenshots: "Take a screenshot at 150% zoom".
 
-**Alex:** Now slow down for the part people usually miss. Put 10. VS Code Settings Reference into plain language. All Copilot customization-related settings. The useful version is: Set in VS Code Settings (Ctrl+,) or settings.json. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** Now slow down for the part people usually miss. Workshop Guidance has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The room should hear these as checkpoints. Treat Browser Agent as a supplementary testing tool, not a replacement for manual testing. Teach learners to write clear test descriptions: "Check for visible text overlaps" vs. "Is it broken?". Use sparingly; each agent session consumes model tokens. For accessibility testing, prefer manual screen reader / keyboard testing + Browser Agent screenshots.
 
 **Jamie:** So this is less about memorizing and more about noticing.
 
 **Alex:** Right. Once the learner can name the move, the interface becomes much less intimidating.
 
-**Jamie:** Let's pause on Deprecated Task-Specific Instructions. What should a learner take away from it?
+**Jamie:** Let's pause on 4E. Plan Agent. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. Prefer file-based instructions over these settings for new work. That is the difference between guessing and knowing: Each accepts an array with items: { "text": "." } (inline) or { "file": "relative/path" } (from file).
+**Alex:** The teaching point here is not the label; it is the move. The Plan Agent is a specialized Copilot agent that breaks down a task into a structured implementation plan before writing code. That is the difference between guessing and knowing: It analyzes your codebase, asks clarifying questions, and produces a step-by-step plan that you can review and refine before implementation starts.
 
 ---
 
-**Jamie:** What is the ordered workflow?
+**Jamie:** Let's pause on How Plan Agent Works. What should a learner take away from it?
 
-**Alex:** This part earns its place because to sync your personal prompts, instructions, and agents across devices. That gives the learner a foothold: your personal.instructions.md,.agent.md, and.prompt.md files will sync to all signed-in VS Code instances.
+**Alex:** How Plan Agent Works has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The path is straightforward once it is named. Step one is ctrl+Shift+P → "Settings Sync: Turn On". Step two is ctrl+Shift+P → "Settings Sync: Configure". Step three is check "Prompts and Instructions". Keep it that plain: know where you are, make the move, check the result.
+**Alex:** The path is straightforward once it is named. Step one is start an agent session and describe your task. Step two is plan Agent analyzes your codebase structure and conventions. Step three is asks clarifying questions to understand requirements ("Should this use TypeScript or JavaScript?"). Step four is generates a plan with concrete steps, file changes, and testing approach. Keep it that plain: know where you are, make the move, check the result.
 
-**Jamie:** Give me the sequence, because order matters here.
+**Jamie:** Before we leave How Plan Agent Works, what is the practical point?
 
-**Alex:** View All Loaded Customizations: To see which instruction files, agents, prompts, and skills are currently loaded - and check for errors.
+**Alex:** First, you review and edit the plan inline (if editing is enabled). Then, handoff to implementation - either Plan Agent or another agent executes the plan. After that, agent runs tests and reports success or asks for refinement. Pause after each step and listen for the confirmation before moving on.
 
-**Alex:** Listen for the small confirmations in this list. All agents found and whether they loaded successfully. All prompt/instruction files and their source (workspace vs user vs organization). All skills and their discovery status. Any parse errors or invalid frontmatter.
+**Jamie:** Let's pause on When to Use Plan Agent. What should a learner take away from it?
 
-**Alex:** First, configure Chat Gear: Click the gear () icon in the Copilot Chat header → "Diagnostics". Then, right-click method: Right-click in the Chat view → "Diagnostics". Pause after each step and listen for the confirmation before moving on.
+**Alex:** When to Use Plan Agent has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** What does the learner do first, second, and then after that?
+**Alex:** Here is the part to remember. Complex features requiring multi-file changes. Unfamiliar codebases where structure isn't obvious. When design review is important before implementation. When you want to validate the approach before committing. Team workflows where plan review is a step before coding.
 
-**Alex:** copilot-instructions.md not being followed has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** This is where confidence starts to build. Accessibility & Planning Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Start here: Confirm the file is at exactly.github/copilot-instructions.md (relative to workspace root). Then: Check the file is plain Markdown with no frontmatter syntax errors. Next: Open Diagnostics to confirm it appears in the loaded files list. Last: Some instructions work better with specific phrasing; use imperative mood ("Always use."). The point is not speed; the point is never losing your place.
+**Alex:** Here is the part to remember. Plan Agent generates structured text outlines, easy to navigate with headings. Press H to jump between steps in the plan. Use Alt+F2 to read full plans in Accessible View. Inline plan editing (if enabled) is keyboard-friendly; Tab to edit fields. Plans are text-based with clear step numbers; zoom as needed. Headings are large and bold; navigate with heading jumps.
 
 ---
 
-**Jamie:** Turn that into a path someone can follow.
+**Jamie:** What should feel predictable before the first live session starts?
+
+**Alex:** This is the move inside Workshop Guidance: introduce Plan Agent as a design-first approach.
+
+**Alex:** Here is the part to remember. Use it for larger features or refactors. Teach learners to ask clarifying questions back to the plan. Emphasize code review: "Is this plan what you expected?". Use Plan Agent output as documentation for your team.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on 4F. Copilot Spaces - Team Knowledge Base. Copilot Spaces (in preview) lets teams create a shared knowledge base that Copilot uses when answering questions. This is the part to say slowly: A Space includes documentation, codebases, and domain knowledge, all indexed for fast retrieval by AI.
+
+**Jamie:** Let's pause on What is a Copilot Space? What should a learner take away from it?
+
+**Alex:** The reason this matters is simple: when someone uses Copilot in the Space, the AI uses that knowledge to provide more accurate, context-aware answers.
+
+**Alex:** Here is the part to remember. Project documentation. Code repositories. Architectural guides. API documentation. Team conventions and style guides. Links to external resources.

+**Alex:** Keep the teaching thread moving. Why Copilot Spaces Matter has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Consistency: All team members get answers grounded in the same authoritative sources. Onboarding: New team members get expert-level context immediately. Domain expertise: Copilot learns your project's conventions, architecture, and best practices. Reduced hallucinations: Fewer wrong or outdated answers.
+
+**Jamie:** Let's pause on How to Create a Copilot Space. What should a learner take away from it?
+
+**Alex:** How to Create a Copilot Space has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Link GitHub repositories. Add documentation links (GitHub Pages, wikis, external docs). Upload or reference team guides.
+
+**Alex:** Start here: Go to github.com/copilot/spaces. Then: Click Create a new Space. Next: Name your Space (e.g., "My Project Team"). Last: Add repositories and documentation. The sequence works because every action has a confirmation.
+
+**Jamie:** Before we leave How to Create a Copilot Space, what is the practical point?
+
+**Alex:** Walk it in order: Configure access (public, private, organization-only); and Save and share the Space URL with your team. Keep it that plain: know where you are, make the move, check the result.
+
+**Jamie:** Let's pause on Using a Copilot Space. What should a learner take away from it?
+
+**Alex:** Using a Copilot Space has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Walk it in order: Open Copilot Chat in VS Code or GitHub; Select your Space from the Space picker (top of Chat); and Ask questions - Copilot uses the Space knowledge. Keep it that plain: know where you are, make the move, check the result.
+
+**Jamie:** Before we leave Using a Copilot Space, what is the practical point?
+
+**Alex:** Think of this as 1 checks: Copilot searches the Space and returns context-aware answers. Pause after each step and listen for the confirmation before moving on.
+
+---
+
+**Jamie:** Let's pause on Accessibility & Team Workflows. What should a learner take away from it?
+
+**Alex:** Accessibility & Team Workflows has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Space configuration is fully keyboard-accessible on github.com. Use H to navigate section headings when setting up a Space. The Space picker in Chat is a keyboard-navigable dropdown. Documentation links in the Space are announced as regular links. Space configuration has good color contrast on GitHub.com. Zoom in on the Space picker to see available options.
+
+**Alex:** Keep the teaching thread moving. Workshop Guidance has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Treat Copilot Spaces as an advanced team feature (not for individual learners). If your workshop uses an organization Space, mention it as a reference context for facilitators. Point out: "Your facilitator may have created a Copilot Space with workshop documentation. Select it from the Space picker to get team-specific answers.". Link to Spaces documentation as a post-workshop resource.
+
+**Jamie:** Let's pause on 5. Custom Instructions - All Levels. What should a learner take away from it?
+
+**Alex:** 5. Custom Instructions - All Levels: GitHub Copilot supports multiple ways to provide custom instructions. The next useful detail is concrete: They differ by scope, priority, trigger mechanism, and which tools recognize them.
+
+---
+
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. What it is: The primary VS Code Copilot instruction file. Put another way, content is automatically included in every chat request and inline suggestion context - you never need to invoke it.
+
+**Jamie:** Let's pause on Auto-generate with /init. What should a learner take away from it?
+
+**Alex:** Auto-generate with /init has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Walk it in order: Open Copilot Chat; Type /init; VS Code analyzes your workspace and generates a tailored copilot-instructions.md; and Review and edit the result before committing. That is the rhythm: orient, act, verify, continue.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on 4B. Always-On Instructions - AGENTS.md (Multi-Tool / Monorepo). What it is: An open standard instruction file recognized by multiple AI tools - GitHub Copilot, Claude Code, Gemini CLI, and others. This is the part to say slowly: Use this instead of copilot-instructions.md when you want one instruction file that works across all AI coding assistants. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+
+---
+
+**Jamie:** Let's pause on 4C. Always-On Instructions - CLAUDE.md (Cross-Tool Compatibility). What should a learner take away from it?
+
+**Alex:** The reason this matters is simple: what it is: Instructions file originally from Claude Code that VS Code Copilot also recognizes. The listener should be able to check this: When to use: Mixed AI tool environments where Claude Code and VS Code Copilot are both used.
+
+**Alex:** Keep the teaching thread moving. Do not treat Supported locations as decoration. Enable/disable: Set chat.useClaudeMdFile: true (default: on). That is not trivia. Claude Rules format (for.claude/rules/ and /.claude/rules/).
+
+**Jamie:** Let's pause on 4D. Conditional / Scoped Instructions -.instructions.md. What should a learner take away from it?
+
+**Alex:** If the interface shifts, 4D. Conditional / Scoped Instructions -.instructions.md is still useful because what it is: Instructions that apply only when specific file types or folders are involved in the chat. For someone navigating by keyboard or screen reader, this detail matters: More targeted than always-on instructions.
+
+---
+
+**Alex:** Keep the teaching thread moving. Create an instructions file has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Ctrl+Shift+P → "Chat: New Instructions File" → choose scope (Workspace or User). Or create the file manually in.github/instructions/.
+
+**Jamie:** Let's pause on 4E. Organization-Level Instructions (GitHub Enterprise and Teams). What should a learner take away from it?
+
+**Alex:** The teaching point here is not the label; it is the move. What it is: Organization administrators define custom instructions that apply to all repositories in the organization. That is the difference between guessing and knowing: Every team member automatically gets these instructions added to their Copilot context.
+
+**Alex:** Keep the teaching thread moving. This part earns its place because use for: Organization-wide coding standards, security policies, legal disclaimers (open source license obligations), toolchain conventions.
+
+**Alex:** Here is the part to remember. GitHub Enterprise or Teams plan with Copilot enabled. Admin configures instructions in organization settings on GitHub.com. Each user must enable discovery in VS Code.
+
+---
+
+**Jamie:** Let's pause on 4F. Settings-Based Instructions (Deprecated - Use Files Instead). What should a learner take away from it?
+
+**Alex:** 4F. Settings-Based Instructions (Deprecated - Use Files Instead): These settings-based instructions are deprecated and may be removed in a future VS Code release. The next useful detail is concrete: For new work, use copilot-instructions.md or.instructions.md files.
+
+**Jamie:** What decision is this helping them make?
+
+**Alex:** 4G. Comparison - When to Use Each Approach has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Approach means Always-on? means Multi-tool? means Best. copilot-instructions.md means Workspace means VS Code only means Primary project instructions. AGENTS.md means Workspace + monorepo means All AI tools means Multi-tool teams or large monorepos.
+
+**Jamie:** Let's pause on Learning Cards: Custom Instructions. What should a learner take away from it?
+
+**Alex:** Learning Cards: Custom Instructions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. The three-level scope hierarchy (Organization, Workspace, User) means instructions can come from multiple places -- use Chat Diagnostics (gear icon in Chat header) to list every loaded instruction file and its source.github/copilot-instructions.md is always-on and requires no frontmatter -- just write plain Markdown; screen readers read the source file like any other Markdown document.instructions.md files use YAML frontmatter with applyTo globs -- the frontmatter is the first few lines between --- delimiters; arrow through carefully to verify syntax. The Diagnostics panel (Chat gear, then Diagnostics) lists loaded files in a scrollable pane -- increase font size in VS Code settings if the file paths are hard to read. YAML frontmatter is indentation-sensitive -- enable VS Code's indentation guides (editor.guides.indentation) and use a high-contrast theme so the guide lines are visible. The /init command auto-generates copilot-instructions.md from your workspace -- review the generated file in your editor at your preferred zoom before committing.
+
+---
+
+**Alex:** Keep the teaching thread moving. Anchor this part on 6. Accessible View Workflow. Copilot Chat responses stream in token by token, which can fragment screen reader announcements. This is the part to say slowly: Accessible View (Alt+F2) gives you a complete, static, properly structured version of the response.
+
+**Jamie:** How do you keep commands from becoming magic words?
+
+**Alex:** The reason this matters is simple: VS Code December 2025: The Accessible View now streams dynamically. The listener should be able to check this: You can open it immediately after sending a prompt and follow the response as it arrives - no need to wait for the response to finish before pressing Alt+F2.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Copilot Chat: Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette if your keymap differs; 2. Type your prompt; 3. Press Ctrl+Enter to send; 4. Press Alt+F2 to open Accessible View (open immediately - no need to wait); 5. Follow as the response. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Alex:** Keep the teaching thread moving. NVDA / JAWS has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Up/Down Arrow - read line by line. Ctrl+Home - jump to start. H - navigate by headings (if response has sections). Escape - close Accessible View, return to Chat.
+
+---
+
+**Jamie:** Let's pause on VoiceOver. What should a learner take away from it?
+
+**Alex:** VoiceOver has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. VO+Shift+Down - interact with the Accessible View content. Down Arrow - read line by line. VO+Escape - stop interacting. Escape - close Accessible View.
+
+**Jamie:** Let's pause on Accessible View for Inline Suggestions. What should a learner take away from it?
+
+**Alex:** Put Accessible View for Inline Suggestions into plain language. When a multi-line ghost text suggestion appears in the editor. The useful version is: This is especially important for multi-line suggestions where ghost text is hard to review incrementally.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Do not accept immediately; 2. Press Alt+F2; 3. Accessible View shows: "Suggestion: [full text]"; 4. Read the complete suggestion at your own pace; 5. Press Escape to close; 6. Press Tab to accept, or Escape to reject. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Accessible View for Code Blocks. What should a learner take away from it?
+
+**Alex:** Accessible View for Code Blocks has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Code blocks appear inside elements in Accessible View. Screen readers announce "code block" or "pre-formatted text" at the start. Each line is on its own line (not run together). Indentation is preserved.
+
+---
+
+**Alex:** Keep the teaching thread moving. Learning Cards: Accessible View Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Press Alt+F2 immediately after sending a prompt -- Accessible View now streams dynamically so you can follow along in real time. Navigate Chat responses with Up/Down Arrow; headings, code blocks, and lists are structurally intact in the view. For inline suggestions, press Alt+F2 to read the full ghost text, then Ctrl+/ to insert it directly from the Accessible View. Accessible View renders Chat responses as a static, scrollable pane -- easier to read at high zoom than the streaming Chat panel. Code blocks in Accessible View preserve indentation and syntax -- pair with a high-contrast theme for maximum readability. Ctrl+Home jumps to the start of the response; Ctrl+End to the end -- useful for long multi-section outputs.
+
+**Jamie:** Let's pause on 7. Configuration Scope Reference. What should a learner take away from it?
+
+**Alex:** 7. Configuration Scope Reference: Every Copilot customization file lives at one of three scopes. The next useful detail is concrete: VS Code combines all matching files from all scopes - it is additive, not winner-takes-all.
+
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Files committed to your repository. Put another way, everyone who clones the repo gets them.
+
+---
+
+**Jamie:** Let's pause on User / Personal - Follows You Across Workspaces. What should a learner take away from it?
+
+**Alex:** This is the move inside User / Personal - Follows You Across Workspaces: files in your VS Code profile folder. That matters in practice: Available in every workspace you open.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on Organization - GitHub-Configured (Enterprise/Teams). Configured by administrators in GitHub organization settings. This is the part to say slowly: Automatically applied to all organization members. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+
+**Alex:** Here is the part to remember. Enable discovery: github.copilot.chat.organizationInstructions.enabled: true. Lowest priority - workspace and user instructions override when there is a conflict.
+
+**Jamie:** Let's pause on 8. Instruction Priority and Conflicts. What should a learner take away from it?
+
+**Alex:** The reason this matters is simple: when multiple instruction sources give conflicting guidance, VS Code uses this priority order. The listener should be able to check this: This priority applies to conflicts.
+
+---
+
+**Alex:** Keep the teaching thread moving. Do not treat How Instructions Are Combined as decoration. Result: Copilot follows TypeScript strict mode (from workspace), British English (from org), AND the Z-spelling override (from user, which overrides the org instruction on that specific point).
+
+**Alex:** Here is the part to remember. Organization: "Use British English spellings". Workspace: "Use TypeScript strict mode". User: "Use British English spellings - but use Z spellings (organize, not organise) for technical terms".
+
+**Jamie:** Let's pause on Priority Within the Same Scope. What should a learner take away from it?
+
+**Alex:** If the interface shifts, Priority Within the Same Scope is still useful because within a single scope (e.g., workspace), all matching instructions files are combined with no inherent priority. For someone navigating by keyboard or screen reader, this detail matters: If two workspace-level.instructions.md files contradict each other, the behavior is undefined - avoid conflicting workspace instructions.
+
+**Alex:** Keep the teaching thread moving. Put Create any new customization file into plain language. Ctrl+Shift+P → "Chat: New Instructions File" (or "New Prompt File", "New Agent File"). The interface gets easier when it becomes a set of named places instead of a wall of controls.
+
+---
+
+**Jamie:** Let's pause on 10. VS Code Settings Reference. What should a learner take away from it?
+
+**Alex:** The teaching point here is not the label; it is the move. All Copilot customization-related settings. That is the difference between guessing and knowing: Set in VS Code Settings (Ctrl+,) or settings.json.
+
+**Alex:** Keep the teaching thread moving. This part earns its place because prefer file-based instructions over these settings for new work. That gives the learner a foothold: each accepts an array with items: { "text": "." } (inline) or { "file": "relative/path" } (from file).
+
+**Jamie:** Let's pause on Settings Sync. What should a learner take away from it?
+
+**Alex:** Settings Sync: To sync your personal prompts, instructions, and agents across devices. The next useful detail is concrete: Your personal.instructions.md,.agent.md, and.prompt.md files will sync to all signed-in VS Code instances.
+
+**Alex:** First, ctrl+Shift+P → "Settings Sync: Turn On". Then, ctrl+Shift+P → "Settings Sync: Configure". After that, check "Prompts and Instructions". Pause after each step and listen for the confirmation before moving on.
+
+---
+
+**Jamie:** Let's pause on View All Loaded Customizations. What should a learner take away from it?
+
+**Alex:** Here is the learner-facing version. To see which instruction files, agents, prompts, and skills are currently loaded - and check for errors. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Alex:** Here is the part to remember. All agents found and whether they loaded successfully. All prompt/instruction files and their source (workspace vs user vs organization). All skills and their discovery status. Any parse errors or invalid frontmatter.
+
+**Alex:** Start here: Configure Chat Gear: Click the gear () icon in the Copilot Chat header → "Diagnostics". Then: Right-click method: Right-click in the Chat view → "Diagnostics". The point is not speed; the point is never losing your place.
+
+**Jamie:** Let's pause on copilot-instructions.md not being followed. What should a learner take away from it?
+
+**Alex:** copilot-instructions.md not being followed has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Walk it in order: Confirm the file is at exactly.github/copilot-instructions.md (relative to workspace root); Check the file is plain Markdown with no frontmatter syntax errors; Open Diagnostics to confirm it appears in the loaded files list; and Some instructions work better with specific phrasing; use imperative mood ("Always use."). Each step should leave a trace you can name.
+
+**Jamie:** Let's pause on.instructions.md file not loading automatically. What should a learner take away from it?
 
 **Alex:** .instructions.md file not loading automatically has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Walk it in order: Verify chat.includeApplyingInstructions is not set to false; Check the applyTo glob - test with " " temporarily to confirm the file loads at all; Confirm the file is in.github/instructions/ or a folder listed in chat.instructionsFilesLocations; and File extension must be.instructions.md exactly - not.md, not.instruction.md. Each step should leave a trace you can name.
+**Alex:** Think of this as 4 checks: Verify chat.includeApplyingInstructions is not set to false; Check the applyTo glob - test with " " temporarily to confirm the file loads at all; Confirm the file is in.github/instructions/ or a folder listed in chat.instructionsFilesLocations; and File extension must be.instructions.md exactly - not.md, not.instruction.md. If one step does not match what you hear, stop there and re-orient.
+
+---
 
 **Jamie:** Let's pause on Custom agent (@agent-name) not appearing. What should a learner take away from it?
 
 **Alex:** Custom agent (@agent-name) not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Think of this as 4 checks: File must be named.agent.md and placed in.github/agents/; Check YAML frontmatter for syntax errors - use a YAML validator; Confirm user-invocable is not set to false (which hides it from the picker); and Run Ctrl+Shift+P → "Reload Window" after any changes to agent files. If one step does not match what you hear, stop there and re-orient.
+**Alex:** The path is straightforward once it is named. Step one is file must be named.agent.md and placed in.github/agents/. Step two is check YAML frontmatter for syntax errors - use a YAML validator. Step three is confirm user-invocable is not set to false (which hides it from the picker). Step four is run Ctrl+Shift+P → "Reload Window" after any changes to agent files. That is the rhythm: orient, act, verify, continue.
 
 **Jamie:** Let's pause on Slash command (/command) not appearing. What should a learner take away from it?
 
 **Alex:** Slash command (/command) not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The path is straightforward once it is named. Step one is file must be at.github/prompts/.prompt.md. Step two is extension must be.prompt.md exactly. Step three is reload VS Code: Ctrl+Shift+P → "Reload Window". That is the rhythm: orient, act, verify, continue.
-
----
+**Alex:** First, file must be at.github/prompts/.prompt.md. Then, extension must be.prompt.md exactly. After that, reload VS Code: Ctrl+Shift+P → "Reload Window". That small check between steps is what makes the workflow reliable.
 
 **Jamie:** Let's pause on Instructions from different files conflicting. What should a learner take away from it?
 
 **Alex:** Instructions from different files conflicting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** First, open Diagnostics to see all loaded instruction files. Then, remove or edit conflicting instructions - they are not automatically de-duplicated. After that, user-level instructions override workspace instructions for the same topic. That small check between steps is what makes the workflow reliable.
+**Alex:** Start here: Open Diagnostics to see all loaded instruction files. Then: Remove or edit conflicting instructions - they are not automatically de-duplicated.

 **Jamie:** Let's pause on Step 1: Enable VS Code Screen Reader Mode. What should a learner take away from it?
 
-**Alex:** This part earns its place because when Screen Reader Mode is on, VS Code changes how it announces suggestions (full text instead of streaming), adjusts live regions, and enables accessible navigation patterns throughout the editor. That is the difference between following directions and owning the workflow.
+**Alex:** Step 1: Enable VS Code Screen Reader Mode: When Screen Reader Mode is on, VS Code changes how it announces suggestions (full text instead of streaming), adjusts live regions, and enables accessible navigation patterns throughout the editor.
 
-**Alex:** The path is straightforward once it is named. Step one is press Shift+Alt+F1 to toggle Screen Reader Accessibility Mode. Step two is or use Command Palette: Ctrl+Shift+P → "Toggle Screen Reader Accessibility Mode". Step three is VS Code announces: "Screen Reader Accessibility Mode enabled". The point is not speed; the point is never losing your place.
+**Alex:** First, press Shift+Alt+F1 to toggle Screen Reader Accessibility Mode. Then, or use Command Palette: Ctrl+Shift+P → "Toggle Screen Reader Accessibility Mode". After that, VS Code announces: "Screen Reader Accessibility Mode enabled". Each step should leave a trace you can name.

-**Alex:** The room should hear these as checkpoints. The golden rule: never accept a suggestion with Tab before reviewing it -- press Alt+F2 first, read it, then Ctrl+/ to insert. Enable the four Copilot audio signals (inline suggestion, request sent, response pending, response received) for non-verbal status awareness. Ctrl+Enter opens a Suggestions Panel with up to 10 alternatives -- navigate with H for headings, then Tab to the Accept button.

+
+**Alex:** Here is the part to remember. Cloud agents are powerful for real-world workflows, but the workshop focuses on understanding the underlying concepts first. Teach learners to review agent PRs carefully - they're still AI-generated and need human judgment. Show an example: "Here's a PR created by Copilot Cloud. Notice the changes and think about whether they match the original requirements.". Emphasize: Agents are accelerators, not replacements for code review.

+**Alex:** Walk it in order: Pre-workshop communication: Explain the limits and suggest they upgrade temporarily for paid plans' benefits; Task design: Use short, focused prompts that consume fewer tokens; Alternative: Education benefits: Verified students may be eligible for GitHub Education benefits including free Copilot Pro; and Time management: Encourage learners to plan their chat questions before asking to avoid wasted tokens. The sequence works because every action has a confirmation.
+
+**Jamie:** Before we leave Workshop Guidance for Free Plan Users, what is the practical point?
+
+**Alex:** Think of this as 1 checks: Completion workflow: Teach local inline suggestions first (ghost text), then introduce Chat later to preserve the monthly limit. Keep it that plain: know where you are, make the move, check the result.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on Copilot Pro Comparison: When to Recommend an Upgrade. Recommend Copilot Pro ($10/month) for workshops if. This is the part to say slowly: Many learners find the $10/month cost is worthwhile to remove friction during intensive learning.
+
+**Alex:** Here is the part to remember. Your exercises involve Copilot Chat extensively. You want learners to experiment freely without token anxiety. The workshop lasts multiple days (Free plan limits reset monthly, but daily resets don't exist). You use custom instructions or multiple models.

+
+**Alex:** If the interface shifts, Managing Usage is still useful because users see their credit consumption in GitHub Settings - Copilot under Usage & Billing.
+
+**Alex:** Here is the part to remember. Advise learners to monitor their usage if they're on a limited plan. Set expectations: "A typical multi-turn chat conversation costs 5-50 credits depending on the model". Recommend Auto model selection to balance quality and cost. Mention monthly resets if learners are concerned about billing.

Use T to navigate pricing tables; arrow keys move between cells. Pricing is typically in the leftmost column of each table. Plan pricing page uses clear, high-contrast pricing tables.

Press Ctrl+Shift+P then "Accept" or "Discard" to confirm or reject each proposed edit; nothing is saved until you explicitly accept. Review each file's diff individually with arrow keys before accepting to ensure Copilot did not introduce errors. Proposed changes appear as standard diff views with green/red highlighting for added/removed lines. Start with a small working set (2-3 files) so the diff review is manageable at high zoom.

 **Alex:** Here is the part to remember. Agent mode's terminal command approval dialogs are announced differently by NVDA ("dialog") vs JAWS ("message box") vs VoiceOver ("alert") -- learn your screen reader's announcement so you recognize approval prompts instantly. Listen for the confirmation prompt before any terminal command executes -- pressing Enter without reading the command is the single highest-risk action in Agent mode. Use Accessible View (Alt+F2) to review the multi-step plan Agent mode proposes before approving; the plan is often too long for live region announcements to capture fully. Agent mode's progress appears in the Chat panel -- if your zoom level pushes the panel narrow, widen it or pop it out so multi-step status lines do not truncate. Terminal command approval buttons use the same accent color as other VS Code buttons; consider a high-contrast theme so approval prompts stand out from surrounding chat text. Watch the file tabs along the top -- Agent mode opens and edits files automatically, and new tabs appearing is your visual cue that changes are happening.

+
+**Alex:** Here is the part to remember. Treat the Agents window as an advanced workflow surface. It helps you coordinate work, but it does not remove your responsibility to review changes. Prefer worktree isolation for Copilot CLI sessions while learning. It keeps agent edits separate from your active workspace. Use the Files panel sync button before starting a session when your branch may be behind upstream. Read terminal command risk badges if enabled, but still inspect the full command before approving. Run project validation tasks from the Agents window before accepting a completed session. If a session changes more files than expected, stop and review before continuing.

 **Alex:** The useful version is not abstract; it sounds like this. Run the installer command in the VS Code terminal (Ctrl+\) -- it announces progress as it copies agent files to.github/agents/`. After installation, press Ctrl+Shift+E to open the Explorer and navigate to.github/agents/ to verify agent files are present. Edit.github/agents/preferences.md to configure your username, repositories, and notification preferences -- it is a standard Markdown file. The installer creates files in.github/agents/ and.github/prompts/ -- verify in the Explorer sidebar that these folders appeared. Open preferences.md in the editor to set your configuration -- use Ctrl+= to zoom if the YAML frontmatter is hard to read. Agent files use.agent.md extension -- they appear alongside regular Markdown files in the Explorer but are distinguished by their extension.

 **Alex:** Here is the part to remember. The three team tables use standard Markdown table format -- navigate with T (NVDA/JAWS) to jump between tables, then Arrow keys to read cells. Agent names start with @ -- type @ followed by the agent name in Copilot Chat to invoke it (e.g., @daily-briefing). Use Ctrl+Shift+O (symbol outline) in any agent file to navigate between its YAML frontmatter sections (Purpose, Responsibilities, Guardrails). The agent tables are dense -- use Ctrl+= to increase font size or open the file in Markdown Preview (Ctrl+Shift+V) for cleaner rendering. Each team has a distinct table: Team 1 (Accessibility, 26 agents), Team 2 (GitHub Workflow, 15 agents), Team 3 (Developer Tools, 14 agents). Agent files in.github/agents/ have descriptive filenames that match the @agent-name -- browse them in the Explorer to find specific agents.
 
-**Alex:** Keep the teaching thread moving. Put 4. Agents in Detail - Hands-On Reference into plain language. This section walks through several agents in depth so you can see how they work, what they produce, and how to evaluate their output. The useful version is: These examples use GitHub Workflow agents because they build directly on Day 1 skills - but the same patterns apply to every agent in the ecosystem.
+**Alex:** Keep the teaching thread moving. Put 3A. Multi-Platform Deployment - Beyond VS Code into plain language. Chapter 16 introduced GitHub Copilot running in VS Code. The useful version is: But Accessibility Agents run on five platforms, each with its own setup, capabilities, and workflow.
+
+---
+
+**Jamie:** How should someone choose between those options?
+
+**Alex:** The Five Platforms: When to Use Each has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Platform means Best For means Installation Time means Learning Curve. GitHub Copilot (VS Code) means Full-time development, web work, accessibility audits means Low (familiar IDE). Claude Code (CLI) means Fast iteration, scripting, quick experiments means Low (command line).
+
+**Jamie:** What decision is this helping them make?
+
+**Alex:** Platform Comparison: Key Capabilities has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Copilot subscription means Claude Pro means Free tier available means Claude Pro.
+
+**Jamie:** Let's pause on Option 1: Start with GitHub Copilot (Recommended for Most Users). What should a learner take away from it?
+
+**Alex:** Option 1: Start with GitHub Copilot (Recommended for Most Users): You already have Copilot if VS Code is installed. The next useful detail is concrete: Next step: Follow the challenges in Section 4 below.
+
+**Alex:** First, open VS Code. Then, press Ctrl+Alt+I (or View → Copilot Chat ). After that, type @daily-briefing morning briefing. Finally, read the result in the Chat panel. Each step should leave a trace you can name.
+
+---
+
+**Jamie:** What should happen before anyone copies and runs it?
+
+**Alex:** Here is the learner-facing version. Claude Code runs on the command line and offers free tier access (for certain Claude models). Put another way, full setup: See Appendix AA: Installation & Setup - Claude Code.
+
+**Alex:** Here is the part to remember. You want to test agents without VS Code. You prefer terminal workflows. You want quick command-line experimentation.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @anthropic-ai/claude-code; claude code auth; claude code @daily-briefing morning briefing. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** How do you keep commands from becoming magic words?
+
+**Alex:** This is the move inside Option 3: Use Gemini CLI for Free Accessibility: gemini CLI offers free tier access to Gemini models with built-in Google Search. That matters in practice: Full setup: See Appendix AA: Installation & Setup - Gemini CLI.
+
+**Alex:** Here is the part to remember. Budget is a priority. You want Google Search integrated with agent responses. You prefer lightweight CLI tools.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @google/gemini-cli; gemini config set api-key YOUR API KEY Get free key at ai.google.dev; gemini @daily-briefing morning briefing. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on Option 4: Use Claude Desktop for Long Sessions. Claude Desktop is the native Claude application with extended context windows and offline capability. This is the part to say slowly: Full setup: See Appendix AA: Installation & Setup - Claude Desktop. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+
+**Alex:** Here is the part to remember. Working on large documents or codebases. Need longer conversation context (200K tokens+). Offline work on the plane. MCP server integration for custom tools.
+
+---
+
+**Jamie:** Let's pause on Choosing Your Primary Platform. What should a learner take away from it?
+
+**Alex:** Choosing Your Primary Platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Yes → Use GitHub Copilot (VS Code) - it's already there. No → Continue to 2. Yes → Use Claude Desktop for longer sessions or Claude Code for CLI. No → Continue to 3. CLI → Use Gemini CLI (free) or Claude Code. GUI → Use Claude Desktop.
+
+**Alex:** The path is straightforward once it is named. Step one is do you already use VS Code daily? Step two is do you have a Copilot or Claude subscription? Step three is do you prefer CLI or GUI? Step four is are you exploring experimental features? The sequence works because every action has a confirmation.
+
+**Jamie:** What is the safe way to learn from that example?
+
+**Alex:** Do not treat Running the Same Agent on Multiple Platforms as decoration. All agents work the same across platforms, but the workflow differs slightly. That is not trivia. Example: Run @aria-specialist on all five platforms.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Ctrl+Alt+I → Type: @aria-specialist audit this component for ARIA. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Path A: "I use VS Code" (Recommended). What should a learner take away from it?
+
+**Alex:** Path A: "I use VS Code" (Recommended) has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Start here: Install Copilot extension (automatic). Then: Complete all challenges in Section 4 using Copilot Chat. Next: Optionally try Claude Desktop for longer sessions. Last: Explore Appendices AA, AB, AC for advanced features. Pause after each step and listen for the confirmation before moving on.
+
+---
+
+**Jamie:** Let's pause on Path B: "I prefer command line". What should a learner take away from it?
+
+**Alex:** Path B: "I prefer command line" has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Walk it in order: Install Claude Code CLI: npm install -g @anthropic-ai/claude-code; Run agents from terminal; Use Gemini CLI for free tier experimentation; and Refer to Appendix AB for hooks and scripting. The point is not speed; the point is never losing your place.
+
+**Jamie:** Let's pause on Path C: "I want the best of both". What should a learner take away from it?
+
+**Alex:** Path C: "I want the best of both" has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Think of this as 4 checks: Use Copilot in VS Code for daily work; Install Claude Desktop for long-context projects; Keep Gemini CLI for quick experiments; and Switch between platforms as needed per task. Each step should leave a trace you can name.
+
+**Alex:** Keep the teaching thread moving. Screen Reader, Low Vision, and Keyboard Navigation by Platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Screen readers: Full support in Chat panel; use Ctrl+Alt+I to open. Low vision: Zoom independently with Ctrl+=; use High Contrast theme. Keyboard: Full keyboard navigation; all features accessible. Screen readers: Full terminal support (NVDA, JAWS announce all output). Low vision: Terminal zoom and colors configurable. Keyboard: Native CLI keyboard support.
+
+**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
 
 ---
 
+**Jamie:** Let's pause on Next Steps. What should a learner take away from it?
+
+**Alex:** Next Steps: Choose your primary platform and continue with the challenges in Section 4. The next useful detail is concrete: You can switch platforms anytime - all agents work the same way.
+
+**Alex:** Here is the part to remember. Already in VS Code? Go to Section 4 now. Want to try CLI first? Read Appendix AA: Installation then come back to Section 4. Want full platform comparison? See Appendix K: Copilot Reference for detailed feature matrix.

This section walks through several agents in depth so you can see how they work, what they produce, and how to evaluate their output. Put another way, these examples use GitHub Workflow agents because they build directly on Day 1 skills - but the same patterns apply to every agent in the ecosystem. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.

-**Alex:** The teaching point here is not the label; it is the move. Before diving in, it helps to know that custom agents fall into two categories - this distinction affects what tool permissions they need and what they can do. That is the difference between guessing and knowing: Informational agents search, analyze, and report.

-**Alex:** What it does: Sweeps every repository you have access to and builds a prioritized dashboard.
+**Alex:** The reason this matters is simple: sweeps every repository you have access to and builds a prioritized dashboard.
 
 **Alex:** Here is the part to remember. Issues opened in the last 24 hours. Pull requests waiting for your review. CI failures on your branches. Security and Dependabot alerts. Community reactions to your recent comments.

+**Alex:** Keep the teaching thread moving. Do not treat Example commands as decoration. The briefing output uses heading level 2 for each section. That is not trivia. Use H key (NVDA/JAWS virtual mode) or VO+Command+H (VoiceOver) to jump between: Open Issues, Review Requests, CI Status, Security Alerts, Community Activity. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.

-**Jamie:** How should a learner choose a tool without feeling judged by the choice?

 **Alex:** Here is the part to remember. Agent.agent.md files use YAML frontmatter at the top (between --- delimiters) followed by Markdown body; in VS Code, use Ctrl+G to jump to line 1 and arrow through the frontmatter fields (name, description, tools) before reading the body instructions. When writing your own.agent.md, use VS Code's Outline view (Ctrl+Shift+O) to verify that your Markdown headings (Purpose, Capabilities, Responsibilities) are correctly nested -- malformed headings will not appear in the outline. Before submitting a PR with a new agent file, run the file through a YAML linter (install the YAML extension, or use yamllint from the terminal) -- frontmatter syntax errors silently break agent registration. YAML frontmatter fields are densely packed with colons and quotes; increase your editor font size or use a monospaced font with wide character spacing so name:, description:, and tools: are clearly distinct. The.agent.md files in the agents/ directory follow a consistent structure -- use the file explorer's icon theme or file nesting feature to visually group agent files separately from regular documentation. When reviewing existing agents for contribution ideas, use VS Code's split editor to place the agent file and the README side by side so you can cross-reference the agent's instructions with its documented capabilities.

Multi-agent output appears in sequence in Copilot Chat -- press Alt+F2 after each response to read it in Accessible View before the next agent responds. The three teams are GitHub Workflow (what happened), Accessibility (is it correct), and Developer Tools (fix it) -- choose your entry point based on your current task. Orchestrator responses can be long -- use Accessible View (Alt+F2) or widen the Chat panel to read comfortably at high zoom. The workflow diagrams in this section are described in text -- no visual-only content is required to understand the agent coordination pattern. Each team's agents are listed in the tables in Section 3 -- refer back there to find the right specialist agent.
 
-**Alex:** The teaching point here is not the label; it is the move. Four agents are specifically designed to coordinate others. That is the difference between guessing and knowing: You do not need to use orchestrators to get value from individual agents.

 **Alex:** Here is the part to remember. GitHub Desktop is a native application -- on Windows it uses UI Automation, not a browser DOM; your screen reader's object navigation (NVDA: Insert+Numpad) rather than browse mode is the correct approach for navigating its interface. GitHub CLI (gh) is entirely terminal-based; all output is plain text that your screen reader reads line by line -- pipe verbose output through head -20 or Select-Object -First 20 to avoid overwhelming your speech buffer. Copilot CLI (gh copilot suggest and gh copilot explain) presents interactive prompts in the terminal; listen for the "Run this command? (Y/n)" confirmation before pressing Enter to avoid executing unreviewed commands. GitHub Desktop inherits your Windows display scaling -- if text appears small, increase system-level scaling (Settings Display Scale) rather than looking for an in-app zoom option. Terminal output from gh and gh copilot uses your terminal's font and color settings; configure your terminal profile (Windows Terminal settings or iTerm2 preferences) with a high-contrast color scheme and large font for comfortable reading. Copilot CLI suggestions appear as plain text in the terminal, not in a styled panel -- they are easy to miss among other output; look for the indented suggestion block immediately after your prompt.

-**Alex:** Learning Cards: Agent Ecosystem Overview has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** That shows up in the workshop in a few specific ways. Invoke any agent by typing @agent-name in Copilot Chat (Ctrl+Alt+I or Chat: Open Chat ) -- the autocomplete list is keyboard-navigable with arrow keys. The 55 agents are organized into 3 teams (Accessibility, GitHub Workflow, Developer Tools) -- use H in the team tables to jump between headings. Agent responses appear in the Chat panel; press Alt+F2 (Accessible View) for a structured, non-streaming version. The agent team tables use consistent columns (Agent, Type, What It Does) -- increase font size so the narrow "Type" column remains readable. Agents work in the Chat panel with your current theme and font settings -- no separate UI to configure. The five supported platforms (VS Code, Claude Code, Gemini CLI, Claude Desktop, Codex CLI) share the same agent logic with platform-specific formatting.

-**Alex:** The next point gives the learner a handle. Do not treat 4. Customization Primitives - Decision Guide as decoration. Before creating any file, choose the right primitive for the job. That is not trivia. Each primitive is a different file type with a different purpose, scope, and trigger.

+**Alex:** The next point gives the learner a handle. Do not treat What it monitors as decoration. Risk levels: High (regression), Medium (degraded), Low (improvement opportunity).
 
-**Alex:** Instructions vs Agent? has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on @template-builder - Issue Template Wizard. What should a learner take away from it?
 
-**Alex:** A few details make that real. Instructions guide behavior passively (always-on or file-scoped). Agents perform tasks actively (on-demand, tool-using).
+**Alex:** If the interface shifts, @template-builder - Issue Template Wizard is still useful because this appendix is the authoritative reference for all Accessibility Agents, skills, slash commands, customization primitives, and file formats. For someone navigating by keyboard or screen reader, this detail matters: Updated for Accessibility Agents v5.0.0+ and VS Code 1.120+.
 
-**Alex:** Hold that next to this. Prompt vs Agent? has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Hold that next to this. Put 1. Agent Teams, Roles, and Platforms into plain language. Accessibility Agents v5.0.0+ includes 80+ agents, 25+ skills, and 30+ MCP tools, organized into three teams and five platforms. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
-**Alex:** Here are the anchors worth keeping. Use a prompt for a single focused task you invoke explicitly. Use an agent when the task spans multiple steps, needs different tools, or should work as a subagent for other agents.
+**Alex:** Here are the anchors worth keeping. Copilot: Full support for all agents, skills, and MCP tools. Claude Code: All agents and skills, with some platform-specific limitations. Gemini Code: All agents and skills, with some platform-specific limitations. Codex: All agents and skills, with some platform-specific limitations. CI/CD: MCP tools and reporting agents for automated workflows. Web: Web accessibility, ARIA, keyboard, color, forms, tables, modals, live regions.
 
 **Jamie:** So the learner is not behind if they stop there and check the page.

-**Alex:** Prompt vs Skill? has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on 2. Agent and Skill Table. What should a learner take away from it?
 
-**Alex:** For a learner, the useful signals are concrete. Both appear as / slash commands. Use a prompt for one well-defined task. Use a skill when the workflow bundles scripts, templates, or reference docs alongside the instructions.
+**Alex:** The teaching point here is not the label; it is the move. This table lists all agents and skills, their roles, and platform support. That is the difference between guessing and knowing: For the latest list, see Accessibility Agents Repository.
 
-**Alex:** That connects to another useful point. Instructions vs Hooks? has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** That shows up in the workshop in a few specific ways. All agents can invoke skills as needed. Skills are documented in.github/skills/ /SKILL.md. Skills include: web-severity-scoring, report-generation, markdown-accessibility, framework-accessibility, help-url-reference, lighthouse-scanner, web-scanning, etc.
 
-**Alex:** The parts worth keeping in working memory are these. Instructions guide the agent (non-deterministic). Hooks enforce behavior via shell commands at lifecycle events - they run regardless of what the agent was prompted to do.
+**Alex:** That connects to another useful point. This part earns its place because the repository includes 54+ slash commands, each mapped to a.prompt.md file in.github/prompts/. That gives the learner a foothold: type / in Copilot Chat to open the command menu.

+**Jamie:** Let's pause on 4. Customization Primitives and File Formats. What should a learner take away from it?
 
-**Alex:** Learning Cards: Customization Primitives has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here is what that changes in practice. The decision table maps each file type to its purpose -- navigate with T (next table) in browse mode, then arrow through rows. Key distinction: instructions are passive (always-on guidance), agents are active (on-demand task performers), hooks are deterministic (shell commands at lifecycle events). Use the "Choosing Between Primitives" Q&A pairs below the table to decide which file type fits your need. The 7-row decision table is the single most important reference here -- zoom in on the "When to Use" column for the clearest guidance. Each Q&A pair under "Choosing Between Primitives" is a short paragraph -- easy to scan at high magnification. Color-coded syntax in YAML frontmatter examples benefits from a high-contrast theme with distinct keyword colors.
+**Alex:** 4. Customization Primitives and File Formats: See Appendix K: Copilot Reference for a full guide to customization primitives, file formats, and always-on/file-based instructions.

-**Alex:** Here is the practical turn. Here is the learner-facing version. Every customization file exists at one of three scopes. Put another way, VS Code combines all matching files from all scopes and sends them to the model. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Alex:** Here is the practical turn. 5. Learning Cards: Agent Invocation, Skills, and Cross-Platform Support has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** What does the learner do first, second, and then after that?
+**Alex:** The room should hear these as checkpoints. All agents and skills are invoked by name with the @ prefix (e.g., @web-accessibility-wizard). Use the slash command menu (/) to discover available prompts and skills. Agent output is rendered as Markdown tables and lists; use Alt+F2 for Accessible View. Skills are documented in.github/skills/ /SKILL.md and referenced in agent output. Platform support is shown in agent/skill tables; check for Copilot, Claude, Gemini, Codex, CI/CD icons or text. Agent and skill names are always shown in the chat transcript and output tables.
 
-**Alex:** Priority Order (highest wins in conflicts) has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on 5. Scope and Priority - All Levels. What should a learner take away from it?
 
-**Alex:** Walk it in order: Personal / User-level - your profile instructions override everything; Workspace / Repository-level -.github/copilot-instructions.md, AGENTS.md,.github/agents/.agent.md; and Organization-level - organization-defined custom instructions (lowest priority). The sequence works because every action has a confirmation.

Use Chat Diagnostics (gear icon in Chat header then Diagnostics) to verify your agent loaded successfully -- it lists every agent found, with error details if frontmatter parsing failed. Agent files are small Markdown documents typically under 100 lines -- increase editor font size and use a theme with distinct YAML keyword colors so frontmatter fields stand out. The tools list in frontmatter uses array syntax (["read", "search"]) -- at high zoom, verify commas and quotes are correct since YAML is sensitive to formatting.

+**Alex:** Progressive Loading - How VS Code Loads Skills: Move reference material to references/ folder files.
 
-**Alex:** The path is straightforward once it is named. Step one is discovery ( 100 tokens): Reads name and description to decide if the skill is relevant. Step two is instructions (<5000 tokens): Loads the full SKILL.md body when the skill is relevant. Step three is resources: Additional files (scripts/, references/) only load when explicitly referenced from SKILL.md. The point is not speed; the point is never losing your place.

+**Jamie:** How do you keep commands from becoming magic words?
 
 **Alex:** Configuration Format has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like {; "hooks": {; "PreToolUse": [; {; "type": "command",; "command": ".github/hooks/validate-before-edit.sh",; "timeout": 15; }; ],; "PostToolUse": [; {; "type": "command",; "command": "npx prettier --write",; "windows": "npx.cmd prettier --write",; "timeout". Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** Keep the teaching thread moving. Anchor this part on PreToolUse permission decisions. Permission decisions: "allow" "ask" (prompt user) "deny" (block the tool call). The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.

-**Jamie:** Let's pause on Exit codes. What should a learner take away from it?
+**Jamie:** How should a learner choose a tool without feeling judged by the choice?
 
-**Alex:** Exit codes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** The reason this matters is simple: permission decisions: "allow" "ask" (prompt user) "deny" (block the tool call).
 
-**Alex:** If someone is taking notes, this is the short list. 0 - success; agent continues. 2 - blocking error; agent stops. Other - non-blocking warning.

-**Alex:** Keep the teaching thread moving. Learning Cards: Hooks has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** These are the details that keep the idea from floating away. 0 - success; agent continues. 2 - blocking error; agent stops. Other - non-blocking warning.
 
-**Alex:** Here is the part that makes the next action easier. Hooks are JSON files, not Markdown -- navigate them in the editor with arrow keys; each hook event (e.g., PreToolUse, PostToolUse) is a key in the "hooks" object. Hook output is returned as JSON on stdout -- the "continue" field (true/false) determines whether the agent proceeds; listen for the "stopReason" message if the hook blocks an action. The "permissionDecision" values (allow, ask, deny) control tool access -- ask triggers a confirmation dialog that your screen reader will announce as a standard VS Code dialog. JSON syntax requires careful attention to braces, brackets, and commas -- use VS Code's bracket pair colorization (editor.bracketPairColorization.enabled) and increase font size to verify structure. The hook events table maps each event name to when it fires -- zoom in on the "When It Fires" column to understand the lifecycle timing. Hook errors appear in the agent session output -- look for non-zero exit codes or "continue": false in the output pane.

+**Jamie:** What is the safe way to learn from that example?
 
 **Alex:** Full File Template has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like My Accessibility Agents Preferences; My GitHub Username; your-github-username; Repositories I Work On Most; - community-access/accessibility-agents; - your-org/your-repo; Preferred Output Format; screen-reader-optimized; Notification Priority; Accessibility. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Jamie:** Can you translate that into plain choices?
+**Jamie:** What is the judgment call here?
 
 **Alex:** Preferred Output Format Options has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: "concise" means Bullet points and short summaries, minimal prose. "detailed" means Full context and more explanation in every response. "screen-reader-optimized" means Heading-heavy structure, no tables, explicit empty-state messages.

 **Jamie:** Let's pause on Agent not found when typing @agent-name. What should a learner take away from it?
 
 **Alex:** Agent not found when typing @agent-name has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Think of this as 4 checks: Verify.github/agents/[name].agent.md exists in your open workspace folder; Check that the YAML frontmatter has no syntax errors (missing quotes, wrong indentation); Ctrl+Shift+P → "Reload Window"; and Check that the name field in the frontmatter matches what you are typing. Keep it that plain: know where you are, make the move, check the result.
+**Alex:** The path is straightforward once it is named. Step one is verify.github/agents/[name].agent.md exists in your open workspace folder. Step two is check that the YAML frontmatter has no syntax errors (missing quotes, wrong indentation). Step three is ctrl+Shift+P → "Reload Window". Step four is check that the name field in the frontmatter matches what you are typing. Pause after each step and listen for the confirmation before moving on.
 
 **Jamie:** Let's pause on Instructions not being applied. What should a learner take away from it?
 
 **Alex:** Instructions not being applied has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The path is straightforward once it is named. Step one is for.github/copilot-instructions.md: file must be at workspace root in the.github/ folder. Step two is for.instructions.md: check that applyTo glob matches the file you are editing, and that chat.includeApplyingInstructions is true in VS Code settings. Step three is for AGENTS.md: check that chat.useAgentsMdFile is true. Step four is use Diagnostics view (above) to verify the file was found and loaded. Pause after each step and listen for the confirmation before moving on.
+**Alex:** First, for.github/copilot-instructions.md: file must be at workspace root in the.github/ folder. Then, for.instructions.md: check that applyTo glob matches the file you are editing, and that chat.includeApplyingInstructions is true in VS Code settings.

 **Alex:** Slash command not appearing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Start here: Verify.github/prompts/[name].prompt.md exists. Then: Ctrl+Shift+P → "Reload Window". Next: File must use.prompt.md extension (not just.md). Each step should leave a trace you can name.
+**Alex:** Walk it in order: Verify.github/prompts/[name].prompt.md exists; Ctrl+Shift+P → "Reload Window"; and File must use.prompt.md extension (not just.md). If one step does not match what you hear, stop there and re-orient.
+
+**Jamie:** Let's pause on Smart Actions and Accessibility Agents. What should a learner take away from it?
+
+**Alex:** The teaching point here is not the label; it is the move. VS Code 1.120+ introduces Smart Actions (automated suggestions for commit messages, symbol renaming, error fixing, and semantic search). That is the difference between guessing and knowing: These complement Accessibility Agents by automating routine tasks that don't require conversational reasoning.
+
+---
+
+**Jamie:** Let's pause on Browser Agent and Accessibility Testing. What should a learner take away from it?
+
+**Alex:** This part earns its place because the Browser Agent (Experimental) can open and test web applications, but it requires human verification for accessibility claims. That gives the learner a foothold: pair Browser Agent with manual screen reader testing and structured Accessibility Agents audits. That is the difference between following directions and owning the workflow.
+
+**Alex:** The path is straightforward once it is named. Step one is use Browser Agent to take screenshots and verify layout (quick visual check). Step two is use @web-accessibility-wizard to run structured audit (axe-core, semantic analysis). Step three is do manual screen reader + keyboard testing to verify agent findings. Step four is use Accessibility Agents for remediation guidance and compliance mapping. That small check between steps is what makes the workflow reliable.

+
+**Alex:** The useful version is not abstract; it sounds like this. Tag issues with labels that trigger agent assignments ( agent-review, documentation ). Create a custom instruction or hook that directs agents to consider accessibility. Review agent PRs with Accessibility Agents before merging. Use @compliance-mapping to verify WCAG alignment of agent-generated code.

+**Alex:** Option 1: Start with GitHub Copilot (Recommended for Most Users): You already have Copilot if VS Code is installed. The next useful detail is concrete: Next step: Follow the challenges in Section 4 below.
+
+**Alex:** First, open VS Code. Then, press Ctrl+Alt+I (or View → Copilot Chat ). After that, type @daily-briefing morning briefing. Finally, read the result in the Chat panel. That is the rhythm: orient, act, verify, continue.
+
+**Jamie:** How do you keep commands from becoming magic words?

+**Alex:** Path C: "I want the best of both" has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Think of this as 4 checks: Use Copilot in VS Code for daily work; Install Claude Desktop for long-context projects; Keep Gemini CLI for quick experiments; and Switch between platforms as needed per task. That is the rhythm: orient, act, verify, continue.
+
+---
+
+**Alex:** Keep the teaching thread moving. Screen Reader, Low Vision, and Keyboard Navigation by Platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Screen readers: Full support in Chat panel; use Ctrl+Alt+I to open. Low vision: Zoom independently with Ctrl+=; use High Contrast theme. Keyboard: Full keyboard navigation; all features accessible. Screen readers: Full terminal support (NVDA, JAWS announce all output). Low vision: Terminal zoom and colors configurable. Keyboard: Native CLI keyboard support.
+
+**Jamie:** Let's pause on Next Steps. What should a learner take away from it?
+
+**Alex:** Next Steps: Choose your primary platform and continue with the challenges in Section 4. The next useful detail is concrete: You can switch platforms anytime - all agents work the same way.
+
+**Alex:** Here is the part to remember. Already in VS Code? Go to Section 4 now. Want to try CLI first? Read Appendix AA: Installation then come back to Section 4. Want full platform comparison? See Appendix K: Copilot Reference for detailed feature matrix.
+
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. This section walks through several agents in depth so you can see how they work, what they produce, and how to evaluate their output. Put another way, these examples use GitHub Workflow agents because they build directly on Day 1 skills - but the same patterns apply to every agent in the ecosystem.
+

+
+**Jamie:** Let's pause on Two Types of Agents. What should a learner take away from it?
+
+**Alex:** This is the move inside Two Types of Agents: before diving in, it helps to know that custom agents fall into two categories - this distinction affects what tool permissions they need and what they can do. That matters in practice: Informational agents search, analyze, and report.
+
+**Alex:** Keep the teaching thread moving. Anchor this part on Agent 1: @daily-briefing - Morning Briefing. File.github/agents/daily-briefing.agent.md. This is the part to say slowly: Before you run this agent: You should have manually navigated a repository's Issues tab, read your GitHub Notifications page, understood what a pull request waiting for review looks like, and know the difference between subscribed and participating. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.

 **Jamie:** Let's pause on What it does. What should a learner take away from it?
 
-**Alex:** What it does: Sweeps every repository you have access to and builds a prioritized dashboard.
+**Alex:** The reason this matters is simple: sweeps every repository you have access to and builds a prioritized dashboard.
 
 **Alex:** Here is the part to remember. Issues opened in the last 24 hours. Pull requests waiting for your review. CI failures on your branches. Security and Dependabot alerts. Community reactions to your recent comments.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. The briefing output uses heading level 2 for each section. Put another way, use H key (NVDA/JAWS virtual mode) or VO+Command+H (VoiceOver) to jump between: Open Issues, Review Requests, CI Status, Security Alerts, Community Activity. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.

-**Jamie:** How do we make tool choice feel like access, not pressure?
+---
 
-**Alex:** The reason this matters is simple: the agent can draft a reply. The listener should be able to check this: You review the tone against the Culture & Etiquette guide before posting.

 **Alex:** Output example has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Issues Labeled "good-first-issue"; High Priority; - 45 [accessibility-agents] Add NVDA-specific navigation tips (3 comments, opened 5 days ago); - Priority Score: 8/10 (high community interest, clear scope, no assignee); - Recommended for: First-time.

 **Alex:** Here is the part to remember. Agent.agent.md files use YAML frontmatter at the top (between --- delimiters) followed by Markdown body; in VS Code, use Ctrl+G to jump to line 1 and arrow through the frontmatter fields (name, description, tools) before reading the body instructions. When writing your own.agent.md, use VS Code's Outline view (Ctrl+Shift+O) to verify that your Markdown headings (Purpose, Capabilities, Responsibilities) are correctly nested -- malformed headings will not appear in the outline. Before submitting a PR with a new agent file, run the file through a YAML linter (install the YAML extension, or use yamllint from the terminal) -- frontmatter syntax errors silently break agent registration. YAML frontmatter fields are densely packed with colons and quotes; increase your editor font size or use a monospaced font with wide character spacing so name:, description:, and tools: are clearly distinct. The.agent.md files in the agents/ directory follow a consistent structure -- use the file explorer's icon theme or file nesting feature to visually group agent files separately from regular documentation. When reviewing existing agents for contribution ideas, use VS Code's split editor to place the agent file and the README side by side so you can cross-reference the agent's instructions with its documented capabilities.

Multi-agent output appears in sequence in Copilot Chat -- press Alt+F2 after each response to read it in Accessible View before the next agent responds. The three teams are GitHub Workflow (what happened), Accessibility (is it correct), and Developer Tools (fix it) -- choose your entry point based on your current task. Orchestrator responses can be long -- use Accessible View (Alt+F2) or widen the Chat panel to read comfortably at high zoom. The workflow diagrams in this section are described in text -- no visual-only content is required to understand the agent coordination pattern. Each team's agents are listed in the tables in Section 3 -- refer back there to find the right specialist agent.

 **Alex:** Here is the part to remember. GitHub Desktop is a native application -- on Windows it uses UI Automation, not a browser DOM; your screen reader's object navigation (NVDA: Insert+Numpad) rather than browse mode is the correct approach for navigating its interface. GitHub CLI (gh) is entirely terminal-based; all output is plain text that your screen reader reads line by line -- pipe verbose output through head -20 or Select-Object -First 20 to avoid overwhelming your speech buffer. Copilot CLI (gh copilot suggest and gh copilot explain) presents interactive prompts in the terminal; listen for the "Run this command? (Y/n)" confirmation before pressing Enter to avoid executing unreviewed commands. GitHub Desktop inherits your Windows display scaling -- if text appears small, increase system-level scaling (Settings Display Scale) rather than looking for an in-app zoom option. Terminal output from gh and gh copilot uses your terminal's font and color settings; configure your terminal profile (Windows Terminal settings or iTerm2 preferences) with a high-contrast color scheme and large font for comfortable reading. Copilot CLI suggestions appear as plain text in the terminal, not in a styled panel -- they are easy to miss among other output; look for the indented suggestion block immediately after your prompt.

+**Alex:** The reason this matters is simple: issue: Agent's response is wrong or misses context.
 
 **Jamie:** Before we leave Solutions, what is the practical point?
 
-**Alex:** First, provide more context in your prompt: Be specific about what you need. Then, use @ mentions: Reference specific files or selections (@filename.md, selection). After that, check the agent's prerequisites: Did you do the manual work first? Finally, review the agent's instructions: Open.github/agents/[name].agent.md and read what it's supposed to do. Each step should leave a trace you can name.

Agent responses appear in the Chat panel; press Alt+F2 (Accessible View) for a structured, non-streaming version. The agent team tables use consistent columns (Agent, Type, What It Does) -- increase font size so the narrow "Type" column remains readable. Agents work in the Chat panel with your current theme and font settings -- no separate UI to configure. The five supported platforms (VS Code, Claude Code, Gemini CLI, Claude Desktop, Codex CLI) share the same agent logic with platform-specific formatting.

You hear the move, try the move, and then check what changed.
 
-**Alex:** Prompt vs Agent? has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. Copilot: Full support for all agents, skills, and MCP tools. Claude Code: All agents and skills, with some platform-specific limitations. Gemini Code: All agents and skills, with some platform-specific limitations. Codex: All agents and skills, with some platform-specific limitations. CI/CD: MCP tools and reporting agents for automated workflows. Web: Web accessibility, ARIA, keyboard, color, forms, tables, modals, live regions.
 
-**Alex:** Here is the part to remember. Use a prompt for a single focused task you invoke explicitly. Use an agent when the task spans multiple steps, needs different tools, or should work as a subagent for other agents.

-**Alex:** Keep the teaching thread moving. Prompt vs Skill? has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** If the interface shifts, 2. Agent and Skill Table is still useful because this table lists all agents and skills, their roles, and platform support. For someone navigating by keyboard or screen reader, this detail matters: For the latest list, see Accessibility Agents Repository.
 
-**Alex:** Here is the part to remember. Both appear as / slash commands. Use a prompt for one well-defined task. Use a skill when the workflow bundles scripts, templates, or reference docs alongside the instructions.
+**Alex:** Here is the part to remember. All agents can invoke skills as needed. Skills are documented in.github/skills/ /SKILL.md. Skills include: web-severity-scoring, report-generation, markdown-accessibility, framework-accessibility, help-url-reference, lighthouse-scanner, web-scanning, etc.

+**Alex:** Keep the teaching thread moving. 5. Learning Cards: Agent Invocation, Skills, and Cross-Platform Support has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. The decision table maps each file type to its purpose -- navigate with T (next table) in browse mode, then arrow through rows. Key distinction: instructions are passive (always-on guidance), agents are active (on-demand task performers), hooks are deterministic (shell commands at lifecycle events). Use the "Choosing Between Primitives" Q&A pairs below the table to decide which file type fits your need. The 7-row decision table is the single most important reference here -- zoom in on the "When to Use" column for the clearest guidance. Each Q&A pair under "Choosing Between Primitives" is a short paragraph -- easy to scan at high magnification. Color-coded syntax in YAML frontmatter examples benefits from a high-contrast theme with distinct keyword colors.
+**Alex:** Here is the part to remember. All agents and skills are invoked by name with the @ prefix (e.g., @web-accessibility-wizard). Use the slash command menu (/) to discover available prompts and skills. Agent output is rendered as Markdown tables and lists; use Alt+F2 for Accessible View. Skills are documented in.github/skills/ /SKILL.md and referenced in agent output. Platform support is shown in agent/skill tables; check for Copilot, Claude, Gemini, Codex, CI/CD icons or text. Agent and skill names are always shown in the chat transcript and output tables.

 **Alex:** Here is the part to remember. Use normative language. Write MUST, MUST NOT, SHOULD, SHOULD NOT, and MAY for rules. LLMs respond well to these terms because they reduce ambiguity -- the same words used in WCAG. Example: Keyboard shortcuts MUST NOT override browser or OS shortcuts. Use lists and checklists. Structured lists provide guardrails that keep Copilot on track. Format accessibility requirements as a checklist so no criterion is overlooked. Specify your versions and standards. This application MUST conform to WCAG 2.2 Level AA is more useful than a general reference to accessibility. Include your design system's component names and flag deprecated components explicitly: DeprecatedButton MUST NOT. Focus on what Copilot doesn't already know. Instructions should add net-new information -- your team's conventions, exceptions, and priorities -- not restate what Copilot was trained on.

 **Alex:** Here is the part to remember. Hooks are JSON files, not Markdown -- navigate them in the editor with arrow keys; each hook event (e.g., PreToolUse, PostToolUse) is a key in the "hooks" object. Hook output is returned as JSON on stdout -- the "continue" field (true/false) determines whether the agent proceeds; listen for the "stopReason" message if the hook blocks an action. The "permissionDecision" values (allow, ask, deny) control tool access -- ask triggers a confirmation dialog that your screen reader will announce as a standard VS Code dialog. JSON syntax requires careful attention to braces, brackets, and commas -- use VS Code's bracket pair colorization (editor.bracketPairColorization.enabled) and increase font size to verify structure. The hook events table maps each event name to when it fires -- zoom in on the "When It Fires" column to understand the lifecycle timing. Hook errors appear in the agent session output -- look for non-zero exit codes or "continue": false in the output pane.

+**Alex:** 1. The Capstone Project: The capstone is bigger than one challenge and bigger than one repository. The next useful detail is concrete: Challenge 16 is the checkpoint where you show evidence.
 
-**Alex:** First, choose a mission for a new accessibility agent (or improve an existing one). Then, write an agent file with valid YAML frontmatter. After that, define clear responsibilities and guardrails. Finally, test the agent locally with GitHub Copilot. Pause after each step and listen for the confirmation before moving on.
+**Alex:** First, choose a repository where an agentic contribution would be useful. Then, identify a real audience and a real workflow gap. After that, create or improve an agent, prompt, custom instruction, skill, workflow, or documentation page that helps that repository. Finally, define clear responsibilities and guardrails. Pause after each step and listen for the confirmation before moving on.
 
 **Jamie:** How would you walk the room through that step by step?
 
-**Alex:** Start here: Open a pull request from your fork to the upstream repository. Then: Respond to peer review feedback. The point is not speed; the point is never losing your place.
+**Alex:** Start here: Test the contribution locally or document how it should be tested.

-**Alex:** The next layer is this. What you need before starting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.

+**Alex:** Now bring the learner back to the room. Anchor this part on Time Estimate. Most students complete a workshop-ready capstone in 60 to 90 minutes. This is the part to say slowly: A polished pull request can take longer, especially when the target project has tests, review requirements, or unfamiliar architecture.
 
-**Jamie:** What would you say to someone who is already bracing for this to be too much?
+**Jamie:** How should someone choose between those options?
 
-**Alex:** The reason this matters is simple: a good agent solves a specific, recurring problem.
+**Alex:** The reason this matters is simple: choose a repository where your work can be genuinely useful. The listener should be able to check this: The following table compares the recommended paths.
 
-**Alex:** The parts worth keeping in working memory are these. What task do you repeat? Think about workflow steps from Day 1 and Day 2 that felt repetitive. What would a specialist know? An agent works best when it has deep knowledge of a focused area. What gap exists? Look at the existing agents in Chapter 19. Is there a workflow that no agent covers?
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Best For means Good Contribution Ideas. Accessibility Agents means Learners who want the most direct agent-building path means Add a focused agent, improve guardrails, update docs, refine prompts, improve skills. Learners interested in document accessibility, large print, Office files, web apps, desktop apps, or user workflows means Add a GLOW-focused agent, improve.github customizations, document contributor workflows, propose rule coverage.
 
 **Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
 
-**Alex:** That matters because of the next idea. Do not treat Write your mission statement as decoration. Before writing any code, write a one-sentence mission statement. That is not trivia. "My agent helps [who] by [doing what] when [in what situation].". The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+**Alex:** That matters because of the next idea. Do not treat Choosing Well as decoration. Ask these questions before you choose. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+
+**Alex:** On the ground, that means a few things. Impact: Who would benefit if this contribution were merged? Fit: Does the repository already use agents, prompts, instructions, skills, or automation? Scope: Can you make a useful change in one small pull request? Access: Can you fork the repository or create a draft in your own fork? Safety: Can you define guardrails that prevent the agent from overreaching?

 **Jamie:** Okay, set the room for us. What are we walking into?
 
-**Alex:** If the interface shifts, 3. Phase 2: Write the Agent File is still useful because an agent file is a Markdown file with YAML frontmatter that defines the agent's identity, and a body that contains the agent's instructions. For someone navigating by keyboard or screen reader, this detail matters: Agent files live in the.github/agents/ directory (for GitHub Copilot agents) or in team-specific directories in the accessibility-agents repository.
+**Alex:** If the interface shifts, 3. Project Option: Accessibility Agents is still useful because accessibility Agents is the default capstone path because it is built around agents, prompts, instructions, skills, and accessibility workflows. For someone navigating by keyboard or screen reader, this detail matters: Current local inventory checked May 13, 2026.
+
+**Alex:** This is where the talk moves from concept to action. Why Choose Accessibility Agents has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** This is where the talk moves from concept to action. Put File location and naming into plain language. Example.github/agents/alt-text-validator.md.
+**Alex:** The room should hear these as checkpoints. You want to build or improve an actual agent. You want clear examples to copy and adapt. You want your contribution to help accessibility reviewers, developers, document remediators, GitHub maintainers, or assistive technology users. You want the Challenge 16 autograder path that validates agent frontmatter, responsibilities, and guardrails.
 
 **Jamie:** Now it sounds like a workflow instead of a wall of instructions.
 
 **Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
 
-**Jamie:** Turn that into a path someone can follow.
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
 
-**Alex:** The agent file structure has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Good Accessibility Agents Contributions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Think of this as 2 checks: YAML frontmatter -- metadata between --- markers at the top of the file; and Instructions body -- Markdown content that tells the agent how to behave. Pause after each step and listen for the confirmation before moving on.
+**Alex:** These are the details that keep the idea from floating away. Add a small specialist agent for an uncovered accessibility workflow. Improve an existing agent's guardrails or output format. Update stale counts, platform names, or release-note guidance in documentation. Add examples that show how screen reader, low vision, keyboard-only, and sighted users should use an agent. Improve prompt files so they produce more structured, reviewable output. Improve a skill reference with clearer severity scoring or remediation guidance.

-**Alex:** Before the learner moves on. This part earns its place because vague descriptions result in missed automatic routing. That gives the learner a foothold: weak: Helps with accessibility - Strong: Checks markdown files for accessibility issues, fixes descriptive links and heading hierarchy, and flags alt text for human review The more specific the description, the more reliably Copilot invokes the right agent for. That is the difference between following directions and owning the workflow.
+**Alex:** Before the learner moves on. This part earns its place because gLOW stands for Guided Layout & Output Workflow. That gives the learner a foothold: it is a multi-surface accessibility toolkit for auditing, fixing, converting, and generating accessible documents. That is the difference between following directions and owning the workflow.
 
-**Jamie:** Give me the version that sounds like an instructor, not a manual.
+**Jamie:** What would you say to someone who is already bracing for this to be too much?
 
-**Alex:** Writing the instructions body: The instructions body tells the agent how to behave. The next useful detail is concrete: Write it as if you are briefing a new team member on their first day.
+**Alex:** What GLOW Does has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** If someone is taking notes, this is the short list. Start with identity. "You are a [role] focused on [area].". List responsibilities. What specific tasks does this agent handle? Set guardrails. What should the agent never do? What are its limits? Provide examples. Show what good output looks like.
+**Alex:** If someone is taking notes, this is the short list. Audits Word, Excel, PowerPoint, Markdown, PDF, EPUB, HTML, and CSS for accessibility issues. Auto-fixes Word document issues where the change is deterministic, such as fonts, spacing, emphasis, headings, and margins. Generates ACB-compliant Word templates. Converts documents to Markdown, accessible HTML, Word, EPUB 3, PDF, and DAISY-oriented outputs through MarkItDown, Pandoc, LibreOffice, and related tooling. Provides web, desktop, CLI, VS Code, and Word add-in surfaces. Supports standards profiles such as ACB 2025 Baseline, APH Submission, and Combined Strict.

+**Alex:** Now slow down for the part people usually miss. Why Choose GLOW has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part that makes the next action easier. Create your agent file with Ctrl+N, then Ctrl+S and save to.github/agents/your-agent-name.md -- the Explorer navigates to the folder automatically. Use Ctrl+Shift+O to navigate between YAML frontmatter fields and Markdown headings (Responsibilities, Guardrails) in your agent file. The YAML frontmatter is between --- markers at the top -- your screen reader announces these as horizontal rules. Agent files are standard Markdown -- open Markdown Preview (Ctrl+Shift+V) side by side to verify formatting as you write. The YAML frontmatter at the top uses name: and description: fields -- keep these on separate lines for readability at high zoom. Use a consistent heading hierarchy ( for title, for sections) so the Outline view (Ctrl+Shift+O) shows a clean structure.
+**Alex:** Here is the part that makes the next action easier. You care about documents, large print, Office files, or accessible publishing. You want a smaller agent surface where one contribution can make a visible difference. You want to connect agents to a real product workflow: upload, audit, fix, convert, template, export, review. You want to help users who may not think of themselves as developers.
 
 ---
 
 **Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
 
-**Alex:** This is the move inside 4. Phase 3: Define Responsibilities and Guardrails: responsibilities and guardrails are the most important parts of your agent's instructions. That matters in practice: The autograder checks that both sections exist.
+**Alex:** Good GLOW Contributions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** These are the pieces that turn the idea into a usable move. Add a GLOW agent that helps users choose between Audit, Fix, Template, Export, and Convert workflows. Improve the existing large-print agent instructions with clearer responsibilities and guardrails. Add a prompt for reviewing release notes against current GLOW features. Add custom instructions for web UI accessibility, plain-language findings, or large-print documentation consistency. Write documentation that explains how contributors should test document accessibility changes. Draft an issue for a future agent, such as a plain-language findings reviewer, batch-audit triage assistant, or Word add-in accessibility reviewer.
 
 **Jamie:** That is the kind of detail that keeps a screen reader user oriented.
 
 **Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
 
-**Alex:** Here is the moment where the page starts to make sense. Anchor this part on Writing responsibilities. Responsibilities define what the agent does. This is the part to say slowly: Each responsibility should describe one discrete action the agent can take. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** Here is the moment where the page starts to make sense. GLOW Safety Notes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Listen for the small confirmations in this list. Scan HTML files for tags missing the alt attribute. Check that all elements have visible text or an aria-label. Verify heading levels do not skip (e.g., h1 to h3 without h2). Help with accessibility.
+**Alex:** Listen for the small confirmations in this list. GLOW handles documents that may contain personal, educational, medical, or organizational information. Do not put private user documents into public prompts or issues. Auto-fix workflows must be conservative. An agent should explain proposed fixes and preserve author intent. Large-print rules can affect pagination and layout. Document tradeoffs instead of pretending every fix is neutral. When a rule comes from ACB, APH, Microsoft Accessibility Checker, or WCAG, cite the source or name the profile.
 
 **Jamie:** Where do you want a learner to place their attention here?
 
-**Alex:** The reason this matters is simple: guardrails define what the agent must not do. The listener should be able to check this: They prevent the agent from overstepping, giving harmful advice, or acting without permission.
-
-**Alex:** The useful version is not abstract; it sounds like this. Never auto-fix code without asking the user first. Do not provide medical, legal, or financial advice when discussing accessibility compliance. Limit reviews to the files the user specifies -- do not scan the entire repository. If a finding is uncertain, say so explicitly rather than presenting it as definitive.
+**Alex:** The reason this matters is simple: you may choose another repository if the contribution is meaningful and reviewable. The listener should be able to check this: This can be your own project, a classmate's project, a community repository, or another open source project you care about.

-**Alex:** The next point gives the learner a handle. Learning Cards: Responsibilities and Guardrails has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** This is where the lesson becomes something you can check. Use Responsibilities and Guardrails as exact heading names -- the autograder searches for these strings. Each responsibility should start with a verb (Scan, Check, Verify, Flag) -- this makes them concrete and testable. Guardrails should start with "Never" or "Do not" to set clear boundaries your screen reader identifies as restrictions when reviewing the file. Format responsibilities as a bulleted list (starting with -) for easy scanning at high zoom -- one responsibility per bullet. Keep each guardrail to a single line so it remains visible without horizontal scrolling at your zoom level. Use bold text for emphasis on critical guardrails (e.g., Never modify files without approval ) to improve visual scanning.
+**Alex:** The next point gives the learner a handle. Requirements for Another Repository has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Let's pause on 5. Phase 4: Test Your Agent Locally. What should a learner take away from it?
-
-**Alex:** If the interface shifts, 5. Phase 4: Test Your Agent Locally is still useful because see also: Chapter 18: Fork and Contribute covers the fork-and-PR workflow you will use to submit your agent. For someone navigating by keyboard or screen reader, this detail matters: Before opening a pull request, test your agent to verify it works.
-
-**Jamie:** What does the learner do first, second, and then after that?
+**Alex:** This is where the lesson becomes something you can check. The work must help the repository, not just satisfy the workshop. The contribution must have a clear audience. The contribution must be small enough to review. The contribution must include responsibilities and guardrails when it involves an agent or automated workflow. If you cannot open a pull request, write a review-ready issue or contribution plan instead.
 
-**Alex:** Testing with GitHub Copilot Chat has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Give me the version that sounds like an instructor, not a manual.
 
-**Alex:** That shows up in the workshop in a few specific ways. Understand its mission? Follow its responsibilities? Respect its guardrails?
+**Alex:** Good Contributions in Any Repository has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Walk it in order: Open VS Code with the accessibility-agents repository; Ensure your agent file is saved in.github/agents/; Open GitHub Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette; and Invoke your agent by name: @your-agent-name check this file for accessibility issues. The point is not speed; the point is never losing your place.
+**Alex:** A few details make that real. Add.github/copilot-instructions.md that teaches Copilot the project's accessibility and contribution standards. Add a custom agent for triaging issues, reviewing docs, checking release notes, or auditing accessibility. Add a prompt file for a repeated maintainer task. Improve issue templates or PR templates so contributors provide better accessibility context. Write contributor documentation that explains how to test with keyboard, screen reader, and high contrast workflows.
 
-**Jamie:** What is the ordered workflow?
+**Alex:** Hold that next to this. Put 6. Define Your Mission into plain language. A good capstone mission solves a specific, recurring problem. The useful version is: Write a one-sentence mission statement before editing files. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
-**Alex:** Think of this as 1 checks: Observe the response. Does the agent. Each step should leave a trace you can name.
+**Alex:** Here are the anchors worth keeping. "My agent helps GLOW contributors by checking whether release notes describe user-facing document accessibility changes clearly.". "My prompt helps Accessibility Agents maintainers by turning a release note into repo documentation updates with screen reader, low vision, and sighted guidance.". "My custom instructions help my project avoid inaccessible React patterns when Copilot generates forms and dialogs.".
 
 **Jamie:** So the learner is not behind if they stop there and check the page.

-**Alex:** This part earns its place because if the agent does not behave as expected. That gives the learner a foothold: most students iterate 2-3 times before they are satisfied.
+**Alex:** The teaching point here is not the label; it is the move. Your asset may be an agent file, prompt file, instruction file, skill, or documentation update. That is the difference between guessing and knowing: If you are writing an agent, use the structure below.
 
-**Alex:** The path is straightforward once it is named. Step one is read its instructions carefully. Is anything ambiguous? Step two is add more specific instructions or examples. Step three is test again with the same prompt. Step four is repeat until the behavior matches your intent. If one step does not match what you hear, stop there and re-orient.

-
-**Alex:** On the ground, that means a few things. Open Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette, then type @your-agent-name followed by a test prompt -- your screen reader announces the response as it streams. Press Alt+F2 after the response finishes to read the full output in Accessible View with arrow keys. If the agent does not respond as expected, edit the.agent.md file and ask again -- Copilot picks up changes immediately. Agent responses appear in the Copilot Chat panel -- widen the panel by dragging its left edge for better readability. Test with a simple prompt first (e.g., "review this file") and read the full response before trying complex requests. Use Accessible View (Alt+F2) to read responses at your preferred editor font size instead of the Chat panel's default.

-
-**Alex:** Here is the learner-facing version. VS Code Desktop (primary for Day 2). A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Alex:** Here is the practical turn. Learning Cards: Writing the Asset has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Start here: Push your branch: Ctrl+Shift+P Git: Push. Then: Ctrl+Shift+P GitHub Pull Requests: Create Pull Request. Next: Set base repo to Community-Access/accessibility-agents, fill in the title and description. Last: Navigate to your fork on GitHub. That small check between steps is what makes the workflow reliable.
+**Alex:** Here is what that changes in practice. Use the Command Palette to create or open files, then save the asset in the target repository's expected folder. Use Ctrl+Shift+O to move by heading and confirm that Responsibilities and Guardrails are easy to find. Use Alt+F2 for long Copilot responses while testing the agent. Keep frontmatter fields on separate lines and use a consistent heading hierarchy. Use Markdown Preview to verify that headings, lists, and examples are visually clear. Avoid long single-line bullets that require horizontal scrolling at high zoom.
 
-**Jamie:** Before we leave Tool Cards: Open Your Capstone PR, what is the practical point?
+**Jamie:** Let's pause on 8. Test Locally. What should a learner take away from it?
 
-**Alex:** Walk it in order: Click Contribute Open pull request; and Verify the base is Community-Access/accessibility-agents:main and the compare is your branch. The sequence works because every action has a confirmation.
+**Alex:** This is the move inside 8. Test Locally: before opening a pull request, test or review your work.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git push -u origin your-branch; gh pr create --repo Community-Access/accessibility-agents. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Jamie:** That is a useful checkpoint before anyone starts pressing keys.
 
-**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+**Alex:** Exactly. Checkpoints turn uncertainty into information.

[ ] Your agent file has a Guardrails section. [ ] The file is in the correct directory. [ ] You have committed and pushed to your fork.
+**Alex:** Think of this as 4 checks: Open VS Code with the target repository; Save your agent, prompt, instruction, or documentation file; Open GitHub Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette; and Invoke the agent or prompt if supported. Example: @plain-language-findings review this audit finding for clarity. Keep it that plain: know where you are, make the move, check the result.

Each autograder check is listed with a pass/fail status and point value -- listen for "10/10" or "0/15" to identify which checks need attention. If a check fails, read the failure message, fix the issue locally, commit, push, and the autograder re-runs automatically. The autograder results appear as a comment with a table showing checks, points, and pass/fail status -- zoom with Ctrl+= to read the details. Green checkmarks indicate passing checks; red X marks indicate failures -- pair with High Contrast theme for clearest visibility.

-**Alex:** These are the details that keep the idea from floating away. A focused mission (not "help with accessibility" -- something specific). At least 3 concrete responsibilities. At least 3 meaningful guardrails. A PR description that explains the agent's purpose. All autograder checks passing.
+**Alex:** Now shift from knowing the term to using it. What Exceeds Expectations Looks Like has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Let's pause on What "exceeds expectations" looks like. What should a learner take away from it?
+**Alex:** Here is the part to remember. The contribution includes examples of expected input and output. The PR description explains tradeoffs and limitations. The learner tests with Copilot Chat or the VS Code Agents window and documents the result. The learner responds thoughtfully to review feedback. The contribution improves existing documentation, counts, or setup instructions alongside the agentic asset.

-**Alex:** This is where confidence starts to build. Anchor this part on 9. Example Agents for Inspiration. These examples show the range of valid agent designs. This is the part to say slowly: Your agent does not need to be this long, but it should be this clear. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
-
-**Jamie:** Let's pause on Example 1: Heading Hierarchy Checker. What should a learner take away from it?
-
-**Alex:** The reason this matters is simple: mission: Validates that HTML and Markdown documents follow a correct heading hierarchy (no skipped levels).
-
-**Alex:** Here is the part to remember. Scan files for heading elements (h1 through h6 in HTML, through in Markdown). Report any instance where a heading level is skipped (e.g., h2 followed by h4). Suggest the correct heading level for each violation. Check that there is exactly one h1 per page. Do not modify files -- only report findings. Do not change heading text, only heading levels.
-
-**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
-
-**Alex:** That connects to another useful point. Do not treat Example 2: PR Description Quality Gate as decoration. Mission: Reviews pull request descriptions to ensure they contain enough context for reviewers.
-
-**Alex:** Here is the part to remember. Check that the PR description is at least 50 characters. Verify the description references an issue with Closes XX or Fixes XX. Check for a summary of changes made. Verify the description explains why the change was made, not just what was changed. Never approve or block a PR based solely on description quality. Do not rewrite the description for the author -- suggest improvements.

-**Alex:** If the interface shifts, Example 3: Keyboard Navigation Auditor is still useful because mission: Checks web components for keyboard accessibility compliance.
-
-**Alex:** Here is the part to remember. Verify all interactive elements are reachable via Tab key. Check that custom components have appropriate tabindex values. Validate that focus order follows visual layout. Detect keyboard traps (elements that receive focus but cannot release it via keyboard). Do not modify component code without user approval. Flag potential issues with confidence levels (certain, likely, possible).

-**Alex:** Here is the practical turn. Put The universal safety net into plain language. If everything else fails, post this on your challenge issue. The useful version is: I attempted Challenge 16 and here is what happened: What I tried: [specific actions] What I expected: [what should have happened] What actually happened: [error or unexpected result] What I learned: [even from failure, what do I understand now?]. The interface gets easier when it becomes a set of named places instead of a wall of controls.

-**Alex:** The useful version is not abstract; it sounds like this. What task do you repeat? Think about workflow steps from Day 1 and Day 2 that felt repetitive. What would a specialist know? An agent works best when it has deep knowledge of a focused area. What gap exists? Look at the existing agents in Chapter 19. Is there a workflow that no agent covers?
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Best For means Good Contribution Ideas. Accessibility Agents means Learners who want the most direct agent-building path means Add a focused agent, improve guardrails, update docs, refine prompts, improve skills.

Use Ctrl+Shift+O to navigate between YAML frontmatter fields and Markdown headings (Responsibilities, Guardrails) in your agent file. The YAML frontmatter is between --- markers at the top -- your screen reader announces these as horizontal rules. Agent files are standard Markdown -- open Markdown Preview (Ctrl+Shift+V) side by side to verify formatting as you write. The YAML frontmatter at the top uses name: and description: fields -- keep these on separate lines for readability at high zoom. Use a consistent heading hierarchy ( for title, for sections) so the Outline view (Ctrl+Shift+O) shows a clean structure.

Add custom instructions for web UI accessibility, plain-language findings, or large-print documentation consistency.

+**Alex:** The room should hear these as checkpoints. GLOW handles documents that may contain personal, educational, medical, or organizational information. Do not put private user documents into public prompts or issues. Auto-fix workflows must be conservative. An agent should explain proposed fixes and preserve author intent. Large-print rules can affect pagination and layout. Document tradeoffs instead of pretending every fix is neutral. When a rule comes from ACB, APH, Microsoft Accessibility Checker, or WCAG, cite the source or name the profile.

-**Jamie:** Let's pause on Writing guardrails. What should a learner take away from it?
+**Jamie:** Let's pause on 5. Project Option: Another Repository. What should a learner take away from it?
 
-**Alex:** The reason this matters is simple: guardrails define what the agent must not do. The listener should be able to check this: They prevent the agent from overstepping, giving harmful advice, or acting without permission.
+**Alex:** The reason this matters is simple: you may choose another repository if the contribution is meaningful and reviewable. The listener should be able to check this: This can be your own project, a classmate's project, a community repository, or another open source project you care about.
 
-**Alex:** That becomes easier when you listen for these cues. Never auto-fix code without asking the user first. Do not provide medical, legal, or financial advice when discussing accessibility compliance. Limit reviews to the files the user specifies -- do not scan the entire repository. If a finding is uncertain, say so explicitly rather than presenting it as definitive.
+**Alex:** Another way to ground it. Requirements for Another Repository has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Another way to ground it. Learning Cards: Responsibilities and Guardrails has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** That becomes easier when you listen for these cues. The work must help the repository, not just satisfy the workshop. The contribution must have a clear audience. The contribution must be small enough to review. The contribution must include responsibilities and guardrails when it involves an agent or automated workflow. If you cannot open a pull request, write a review-ready issue or contribution plan instead.
 
-**Alex:** If someone is taking notes, this is the short list. Use Responsibilities and Guardrails as exact heading names -- the autograder searches for these strings. Each responsibility should start with a verb (Scan, Check, Verify, Flag) -- this makes them concrete and testable. Guardrails should start with "Never" or "Do not" to set clear boundaries your screen reader identifies as restrictions when reviewing the file. Format responsibilities as a bulleted list (starting with -) for easy scanning at high zoom -- one responsibility per bullet. Keep each guardrail to a single line so it remains visible without horizontal scrolling at your zoom level. Use bold text for emphasis on critical guardrails (e.g., Never modify files without approval ) to improve visual scanning.
+**Jamie:** Let's pause on Good Contributions in Any Repository. What should a learner take away from it?
 
-**Jamie:** Let's pause on 5. Phase 4: Test Your Agent Locally. What should a learner take away from it?
+**Alex:** Good Contributions in Any Repository has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** If the interface shifts, 5. Phase 4: Test Your Agent Locally is still useful because see also: Chapter 18: Fork and Contribute covers the fork-and-PR workflow you will use to submit your agent. For someone navigating by keyboard or screen reader, this detail matters: Before opening a pull request, test your agent to verify it works.
+**Alex:** If someone is taking notes, this is the short list. Add.github/copilot-instructions.md that teaches Copilot the project's accessibility and contribution standards. Add a custom agent for triaging issues, reviewing docs, checking release notes, or auditing accessibility. Add a prompt file for a repeated maintainer task. Improve issue templates or PR templates so contributors provide better accessibility context. Write contributor documentation that explains how to test with keyboard, screen reader, and high contrast workflows.

-**Jamie:** Let's pause on Testing with GitHub Copilot Chat. What should a learner take away from it?
-
-**Alex:** Testing with GitHub Copilot Chat has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** These are the pieces that turn the idea into a usable move. Understand its mission? Follow its responsibilities? Respect its guardrails?
-
-**Alex:** Walk it in order: Open VS Code with the accessibility-agents repository; Ensure your agent file is saved in.github/agents/; Open GitHub Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette; and Invoke your agent by name: @your-agent-name check this file for accessibility issues. If one step does not match what you hear, stop there and re-orient.
-
-**Jamie:** Before we leave Testing with GitHub Copilot Chat, what is the practical point?
+**Alex:** This is the part worth saying out loud. Put 6. Define Your Mission into plain language. A good capstone mission solves a specific, recurring problem. The useful version is: Write a one-sentence mission statement before editing files.
 
-**Alex:** Think of this as 1 checks: Observe the response. Does the agent. That is the rhythm: orient, act, verify, continue.
+**Alex:** Here is the part that makes the next action easier. "My agent helps GLOW contributors by checking whether release notes describe user-facing document accessibility changes clearly.". "My prompt helps Accessibility Agents maintainers by turning a release note into repo documentation updates with screen reader, low vision, and sighted guidance.". "My custom instructions help my project avoid inaccessible React patterns when Copilot generates forms and dialogs.".
 
 **Jamie:** I like that because it gives people permission to slow down.
 
 **Alex:** That is the goal. We want the page to feel explorable, not fragile.
 
-**Jamie:** Let's pause on Testing checklist. What should a learner take away from it?
+**Jamie:** Let's pause on 7. Write or Improve the Agentic Asset. What should a learner take away from it?
 
-**Alex:** Testing checklist has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** The teaching point here is not the label; it is the move. Your asset may be an agent file, prompt file, instruction file, skill, or documentation update. That is the difference between guessing and knowing: If you are writing an agent, use the structure below.
 
-**Alex:** Listen for the small confirmations in this list. [ ] The agent responds when invoked by name. [ ] The agent stays within its defined responsibilities. [ ] The agent does not violate any guardrails. [ ] The agent's output is useful and specific. [ ] The agent handles edge cases gracefully (empty files, no issues found).
-
-**Jamie:** Let's pause on Iterating on your agent. What should a learner take away from it?
-
-**Alex:** This part earns its place because if the agent does not behave as expected. That gives the learner a foothold: most students iterate 2-3 times before they are satisfied. That is the difference between following directions and owning the workflow.
-
-**Alex:** The path is straightforward once it is named. Step one is read its instructions carefully. Is anything ambiguous? Step two is add more specific instructions or examples. Step three is test again with the same prompt. Step four is repeat until the behavior matches your intent. That small check between steps is what makes the workflow reliable.
+**Alex:** Put that beside the next piece. This part earns its place because follow the target repository's conventions. That gives the learner a foothold: example.github/agents/plain-language-findings.agent.md. That is the difference between following directions and owning the workflow.

-**Jamie:** Let's pause on Learning Cards: Testing Your Agent. What should a learner take away from it?
-
-**Alex:** Learning Cards: Testing Your Agent has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** This is where the lesson becomes something you can check. Open Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette, then type @your-agent-name followed by a test prompt -- your screen reader announces the response as it streams. Press Alt+F2 after the response finishes to read the full output in Accessible View with arrow keys. If the agent does not respond as expected, edit the.agent.md file and ask again -- Copilot picks up changes immediately. Agent responses appear in the Copilot Chat panel -- widen the panel by dragging its left edge for better readability. Test with a simple prompt first (e.g., "review this file") and read the full response before trying complex requests. Use Accessible View (Alt+F2) to read responses at your preferred editor font size instead of the Chat panel's default.

-**Jamie:** Let's pause on Tool Cards: Open Your Capstone PR. What should a learner take away from it?
-
-**Alex:** Here is the learner-facing version. VS Code Desktop (primary for Day 2).

Next: Set base repo to Community-Access/accessibility-agents, fill in the title and description. Last: Navigate to your fork on GitHub. Keep it that plain: know where you are, make the move, check the result.

+**Jamie:** Let's pause on YAML Frontmatter Fields. What should a learner take away from it?
 
-**Alex:** Walk it in order: Click Contribute Open pull request; and Verify the base is Community-Access/accessibility-agents:main and the compare is your branch. Pause after each step and listen for the confirmation before moving on.
+**Alex:** YAML Frontmatter Fields: The following table describes the common agent frontmatter fields.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git push -u origin your-branch; gh pr create --repo Community-Access/accessibility-agents. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+**Alex:** Now shift from knowing the term to using it. Learning Cards: Writing the Asset has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Let's pause on Pre-PR checklist. What should a learner take away from it?
+**Alex:** A few details make that real. Use the Command Palette to create or open files, then save the asset in the target repository's expected folder. Use Ctrl+Shift+O to move by heading and confirm that Responsibilities and Guardrails are easy to find. Use Alt+F2 for long Copilot responses while testing the agent. Keep frontmatter fields on separate lines and use a consistent heading hierarchy. Use Markdown Preview to verify that headings, lists, and examples are visually clear. Avoid long single-line bullets that require horizontal scrolling at high zoom.
 
-**Alex:** Pre-PR checklist has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Let's pause on 8. Test Locally. What should a learner take away from it?
 
-**Alex:** A few details make that real. [ ] Your agent file has valid YAML frontmatter (name and description fields). [ ] Your agent file has a Responsibilities section. [ ] Your agent file has a Guardrails section. [ ] The file is in the correct directory. [ ] You have committed and pushed to your fork.
+**Alex:** This is the move inside 8. Test Locally: before opening a pull request, test or review your work.

-**Alex:** Anchor this part on Open the PR. Follow the pull request steps from Chapter 18, Step 7. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** Testing With GitHub Copilot Chat has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here are the anchors worth keeping. Your mission statement from Phase 1. What the agent does (summary of responsibilities). Any design decisions you made. How you tested it.
+**Alex:** Think of this as 4 checks: Open VS Code with the target repository; Save your agent, prompt, instruction, or documentation file; Open GitHub Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette; and Invoke the agent or prompt if supported. Example: @plain-language-findings review this audit finding for clarity. The point is not speed; the point is never losing your place.

+**Jamie:** Let's pause on Testing Checklist. What should a learner take away from it?
 
-**Jamie:** Let's pause on The autograder. What should a learner take away from it?
+**Alex:** Testing Checklist has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The reason this matters is simple: the repository has an autograding workflow that runs on every pull request. The listener should be able to check this: The autograder posts results as a comment on your PR.
+**Alex:** Listen for the small confirmations in this list. [ ] The contribution has a clear mission. [ ] Responsibilities are specific and action-oriented. [ ] Guardrails prevent overreach. [ ] Output is useful, specific, and accessible. [ ] The contribution follows the target repository's naming and folder conventions. [ ] You documented any limitations or future work.
 
-**Alex:** The next layer is this. Learning Cards: Opening Your Pull Request has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here is what that changes in practice. The autograder comment appears in the PR timeline -- navigate to Comments on GitHub.com with h (heading navigation) to find the results. Each autograder check is listed with a pass/fail status and point value -- listen for "10/10" or "0/15" to identify which checks need attention. If a check fails, read the failure message, fix the issue locally, commit, push, and the autograder re-runs automatically. The autograder results appear as a comment with a table showing checks, points, and pass/fail status -- zoom with Ctrl+= to read the details. Green checkmarks indicate passing checks; red X marks indicate failures -- pair with High Contrast theme for clearest visibility. Your PR description should include your mission statement, responsibilities summary, and testing notes.

+**Alex:** Tool Cards: Open Your Capstone PR has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** If the interface shifts, 7. Phase 6: Respond to Review is still useful because after the autograder passes, a peer reviewer (your buddy or another student) and a facilitator will review your agent.
+**Alex:** First, push your branch: Ctrl+Shift+P then Git: Push. Then, run GitHub Pull Requests: Create Pull Request from the Command Palette. After that, set the base repository to the project you chose. Finally, fill in the title and description. If one step does not match what you hear, stop there and re-orient.
 
-**Alex:** Now bring the learner back to the room. What reviewers look for has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Jamie:** Before we leave Tool Cards: Open Your Capstone PR, what is the practical point?
 
-**Alex:** That shows up in the workshop in a few specific ways. Clarity: Are the instructions easy to understand? Specificity: Are responsibilities concrete and actionable? Safety: Are guardrails sufficient to prevent harmful behavior? Usefulness: Would this agent actually help someone? Scope: Does the agent try to do too much or too little?
+**Alex:** Start here: Navigate to your fork on GitHub. Then: Activate Contribute then Open pull request. Next: Verify the base repository and compare branch. Last: Create the pull request. That is the rhythm: orient, act, verify, continue.

+**Alex:** Now bring the learner back to the room. Put Challenge 16 Evidence into plain language. Post one of these in your Challenge 16 issue. The useful version is: If you use the Accessibility Agents autograder path, it checks agent file structure in agents/ or community-agents/: frontmatter, responsibilities, and guardrails. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
-**Alex:** That matters because of the next idea. This part earns its place because your agent is now part of the accessibility-agents ecosystem. That gives the learner a foothold: it is available to anyone who uses the repository.
+**Alex:** Here is the part to remember. A pull request link. A branch link with the changed file. A draft agent file pasted or linked. A contribution plan with mission, responsibilities, guardrails, and target repository.
 
-**Alex:** Here is the part to remember. You can navigate the fork workflow end to end. You can write clear, structured technical documentation. You understand accessibility concepts well enough to teach an AI agent about them. You can respond constructively to code review.

-
-**Alex:** This is the move inside What "exceeds expectations" looks like: a capstone that exceeds expectations also has.
+**Alex:** That matters because of the next idea. This part earns its place because the capstone is assessed as a real contribution, not just as a file format exercise.
 
-**Alex:** Here is the part to remember. Examples of expected input and output in the agent instructions. A section describing the agent's limitations. Evidence of testing (screenshots or transcripts in the PR description). Thoughtful responses to review feedback.
+**Jamie:** Let's pause on Core Criteria. What should a learner take away from it?
 
-**Alex:** Put that beside the next piece. Anchor this part on 9. Example Agents for Inspiration. These examples show the range of valid agent designs. This is the part to say slowly: Your agent does not need to be this long, but it should be this clear.
+**Alex:** Core Criteria: The following table lists the capstone evaluation criteria.
 
-**Jamie:** Let's pause on Example 1: Heading Hierarchy Checker. What should a learner take away from it?
+**Alex:** This is where confidence starts to build. What Exceeds Expectations Looks Like has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** The reason this matters is simple: mission: Validates that HTML and Markdown documents follow a correct heading hierarchy (no skipped levels).
-
-**Alex:** Here is the part to remember. Scan files for heading elements (h1 through h6 in HTML, through in Markdown). Report any instance where a heading level is skipped (e.g., h2 followed by h4). Suggest the correct heading level for each violation. Check that there is exactly one h1 per page. Do not modify files -- only report findings. Do not change heading text, only heading levels.
-
-**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
+**Alex:** Here is the part to remember. The contribution includes examples of expected input and output. The PR description explains tradeoffs and limitations. The learner tests with Copilot Chat or the VS Code Agents window and documents the result. The learner responds thoughtfully to review feedback. The contribution improves existing documentation, counts, or setup instructions alongside the agentic asset.

-**Alex:** Now shift from knowing the term to using it. Do not treat Example 2: PR Description Quality Gate as decoration. Mission: Reviews pull request descriptions to ensure they contain enough context for reviewers. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
-
-**Alex:** Here is the part to remember. Check that the PR description is at least 50 characters. Verify the description references an issue with Closes XX or Fixes XX. Check for a summary of changes made. Verify the description explains why the change was made, not just what was changed. Never approve or block a PR based solely on description quality. Do not rewrite the description for the author -- suggest improvements.
+**Jamie:** How should someone ask for help in a way that gets them unstuck faster?
 
-**Jamie:** Let's pause on Example 3: Keyboard Navigation Auditor. What should a learner take away from it?
+**Alex:** This is the move inside 12. If You Get Stuck: the following table lists common capstone blockers and recovery steps.
 
-**Alex:** If the interface shifts, Example 3: Keyboard Navigation Auditor is still useful because mission: Checks web components for keyboard accessibility compliance.
+**Alex:** The next layer is this. Anchor this part on The Universal Safety Net. If everything else fails, post this on your Challenge 16 issue. This is the part to say slowly: I attempted the capstone project and here is what happened: Repository I chose: [repository] What I tried: [specific actions] What I expected: [what should have happened] What actually happened: [error or unexpected result] What I learned: [even from failure,.
 
-**Alex:** Here is the part to remember. Verify all interactive elements are reachable via Tab key. Check that custom components have appropriate tabindex values. Validate that focus order follows visual layout. Detect keyboard traps (elements that receive focus but cannot release it via keyboard). Do not modify component code without user approval. Flag potential issues with confidence levels (certain, likely, possible).
+**Jamie:** Let's pause on 55 AI Agents Across 3 Teams and 5 Platforms. What should a learner take away from it?
 
-**Alex:** This is where confidence starts to build. Put The universal safety net into plain language. If everything else fails, post this on your challenge issue.

 **Alex:** Challenge 15 Set has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Walk it in order: Agent Discovery Mapping - identify 3-5 agents that match skills you already have from Day 1; Agent Skill Validation - run one agent and evaluate its output against your manual experience; Agent Instructions Deep Dive - read one agent's source file and assess what it can and cannot do; and Improve an Existing Agent (optional hackathon) - find a gap in an agent's instructions and fix it via PR. That is the rhythm: orient, act, verify, continue.

Pause after each step and listen for the confirmation before moving on.
 
 **Jamie:** Before we leave Challenge 15 Set, what is the practical point?
 
-**Alex:** Think of this as 1 checks: Propose a New Agent (optional hackathon) - file an issue proposing an agent for an uncovered workflow. That small check between steps is what makes the workflow reliable.
+**Alex:** The path is straightforward once it is named. Step one is propose a New Agent (optional hackathon) - file an issue proposing an agent for an uncovered workflow. The point is not speed; the point is never losing your place.
 
 **Jamie:** Let's pause on Challenge 15.1 Step-by-Step: Agent Discovery Mapping. What should a learner take away from it?
 
-**Alex:** Anchor this part on Challenge 15.1 Step-by-Step: Agent Discovery Mapping. Map your Day 1 manual skills to specific agents in the ecosystem so you know which agents you are ready to use. This is the part to say slowly: GitHub.com - the accessibility-agents repository and your assigned Challenge 15 issue. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** This part earns its place because map your Day 1 manual skills to specific agents in the ecosystem so you know which agents you are ready to use. That gives the learner a foothold: GitHub.com - the accessibility-agents repository and your assigned Challenge 15 issue.

 **Alex:** Here is the part to remember. @daily-briefing (maps to repository and issue awareness from Chapters 2-4). @issue-tracker (maps to Chapter 4 issue workflow). @pr-review (maps to Chapter 6 and Chapter 14 review workflow). Example: You filed issues manually (Ch 4) - you can use @issue-tracker.

If an agent produces something you do not understand, stop and learn the manual skill first from the relevant chapter. Agent responses appear in the Copilot Chat panel -- drag the panel wider or use Alt+F2 (Accessible View) for a larger, cleaner reading pane.

+**Jamie:** What should be ready before Day 1, so the room can move together?
 
 **Alex:** Learning Cards: Setup and Configuration has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. Run the installer command in the VS Code terminal (Ctrl+\) -- it announces progress as it copies agent files to.github/agents/`. After installation, press Ctrl+Shift+E to open the Explorer and navigate to.github/agents/ to verify agent files are present. Edit.github/agents/preferences.md to configure your username, repositories, and notification preferences -- it is a standard Markdown file. The installer creates files in.github/agents/ and.github/prompts/ -- verify in the Explorer sidebar that these folders appeared. Open preferences.md in the editor to set your configuration -- use Ctrl+= to zoom if the YAML frontmatter is hard to read. Agent files use.agent.md extension -- they appear alongside regular Markdown files in the Explorer but are distinguished by their extension.
 
-**Alex:** Keep the teaching thread moving. Do not treat 3. The Ecosystem: 55 Agents, 3 Teams, 5 Platforms as decoration. Accessibility Agents is an ecosystem of 55 specialized agents organized into three teams, each addressing a different dimension of accessible software development. That is not trivia.

Put another way, browse all three teams below, then choose the agents that match your current skills and interests. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
 **Jamie:** Let's pause on Team 1: Accessibility (26 agents). What should a learner take away from it?
 
-**Alex:** If the interface shifts, Team 1: Accessibility (26 agents) is still useful because these agents audit, fix, and enforce accessibility across web, document, and mobile platforms.

+**Jamie:** There are a lot of tools in play. How do we keep that from feeling like a contest?

 **Jamie:** Let's pause on Hook-Based Enforcement (Claude Code). What should a learner take away from it?
 
-**Alex:** Hook-Based Enforcement (Claude Code): On Claude Code, Accessibility Agents includes a hook system that enforces accessibility standards automatically. The next useful detail is concrete: This means accessibility enforcement happens whether or not the developer remembers to ask for it.
+**Alex:** If the interface shifts, Hook-Based Enforcement (Claude Code) is still useful because on Claude Code, Accessibility Agents includes a hook system that enforces accessibility standards automatically. For someone navigating by keyboard or screen reader, this detail matters: This means accessibility enforcement happens whether or not the developer remembers to ask for it.
 
-**Alex:** First, proactive detection hook - scans every file edit for accessibility regressions before they are committed. Then, edit gate hook - blocks commits that introduce WCAG violations until they are fixed. After that, session marker hook - tracks which accessibility checks have run during the current session. Each step should leave a trace you can name.
+**Alex:** Start here: Proactive detection hook - scans every file edit for accessibility regressions before they are committed. Then: Edit gate hook - blocks commits that introduce WCAG violations until they are fixed. Next: Session marker hook - tracks which accessibility checks have run during the current session. The sequence works because every action has a confirmation.

+
+**Alex:** Keep the teaching thread moving. Put What Would You Build? into plain language. This is the question that matters most. The useful version is: The 55 agents that exist today were built by contributors who saw a gap and filled it.
 
 **Alex:** Here is the part to remember. "Why is there no agent for [framework] accessibility patterns?". "I spend 30 minutes on [task] every week - could an agent do the repetitive part?". "This agent is good but it misses [specific edge case] - I could improve those instructions". "Mobile native accessibility testing has no agent coverage yet - I could start one".
 
 **Jamie:** Let's pause on The contribution paths are. What should a learner take away from it?
 
-**Alex:** This is the move inside The contribution paths are: see the Accessibility Agents CONTRIBUTING guide for detailed instructions on each path.
+**Alex:** The teaching point here is not the label; it is the move. See the Accessibility Agents CONTRIBUTING guide for detailed instructions on each path.
 
-**Alex:** Walk it in order: Report an agent gap - file an issue describing what is missing and why it matters; Improve existing agent instructions - make an agent smarter about edge cases it misses; Add framework-specific patterns - teach agents about React, Vue, Angular, Svelte, or other framework accessibility patterns; and Fix installer issues - improve the one-liner scripts for different OS configurations. That is the rhythm: orient, act, verify, continue.
+**Alex:** Think of this as 4 checks: Report an agent gap - file an issue describing what is missing and why it matters; Improve existing agent instructions - make an agent smarter about edge cases it misses; Add framework-specific patterns - teach agents about React, Vue, Angular, Svelte, or other framework accessibility patterns; and Fix installer issues - improve the one-liner scripts for different OS configurations. Pause after each step and listen for the confirmation before moving on.
 
 **Jamie:** Before we leave The contribution paths are, what is the practical point?
 
-**Alex:** Think of this as 1 checks: Write documentation - help others understand how to use and contribute to agents. That small check between steps is what makes the workflow reliable.
+**Alex:** The path is straightforward once it is named. Step one is write documentation - help others understand how to use and contribute to agents. The point is not speed; the point is never losing your place.

-**Alex:** Keep the teaching thread moving. Anchor this part on Roadmap: What Is Coming Next. Your contribution could be the next item that ships. This is the part to say slowly: Every agent started as one person's idea and one pull request. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+**Alex:** Keep the teaching thread moving. This part earns its place because your contribution could be the next item that ships. That gives the learner a foothold: every agent started as one person's idea and one pull request. That is the difference between following directions and owning the workflow.
 
 **Alex:** Here is the part to remember. Mobile native agents - agents specialized for iOS (VoiceOver) and Android (TalkBack) native app accessibility. Anthropic Connectors listing - making agents discoverable through the Anthropic marketplace. veraPDF integration - automated PDF/UA validation for the PDF accessibility agent. Document remediation agents - agents that fix accessibility issues in documents, not just find them.

 **Jamie:** Let's pause on Learning Cards: The Agent Ecosystem. What should a learner take away from it?
 
 **Alex:** Learning Cards: The Agent Ecosystem has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. The three team tables use standard Markdown table format -- navigate with T (NVDA/JAWS) to jump between tables, then Arrow keys to read cells. Agent names start with @ -- type @ followed by the agent name in Copilot Chat to invoke it (e.g., @daily-briefing). Use Ctrl+Shift+O (symbol outline) in any agent file to navigate between its YAML frontmatter sections (Purpose, Responsibilities, Guardrails). The agent tables are dense -- use Ctrl+= to increase font size or open the file in Markdown Preview (Ctrl+Shift+V) for cleaner rendering. Each team has a distinct table: Team 1 (Accessibility, 26 agents), Team 2 (GitHub Workflow, 15 agents), Team 3 (Developer Tools, 14 agents). Agent files in.github/agents/ have descriptive filenames that match the @agent-name -- browse them in the Explorer to find specific agents.
 
-**Alex:** Keep the teaching thread moving. Do not treat 4. Agents in Detail - Hands-On Reference as decoration. This section walks through several agents in depth so you can see how they work, what they produce, and how to evaluate their output. That is not trivia. These examples use GitHub Workflow agents because they build directly on Day 1 skills - but the same patterns apply to every agent in the ecosystem.
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Chapter 16 introduced GitHub Copilot running in VS Code. Put another way, but Accessibility Agents run on five platforms, each with its own setup, capabilities, and workflow.
+
+**Jamie:** How should someone choose between those options?
+
+**Alex:** The Five Platforms: When to Use Each has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Platform means Best For means Installation Time means Learning Curve. GitHub Copilot (VS Code) means Full-time development, web work, accessibility audits means Low (familiar IDE). Claude Code (CLI) means Fast iteration, scripting, quick experiments means Low (command line).
+
+---
+
+**Jamie:** What decision is this helping them make?
+
+**Alex:** Platform Comparison: Key Capabilities has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Copilot subscription means Claude Pro means Free tier available means Claude Pro.
+
+**Jamie:** Let's pause on Option 1: Start with GitHub Copilot (Recommended for Most Users). What should a learner take away from it?
+
+**Alex:** The reason this matters is simple: you already have Copilot if VS Code is installed. The listener should be able to check this: Next step: Follow the challenges in Section 4 below.
+
+**Alex:** The path is straightforward once it is named. Step one is open VS Code. Step two is press Ctrl+Alt+I (or View → Copilot Chat ). Step three is type @daily-briefing morning briefing. Step four is read the result in the Chat panel. The sequence works because every action has a confirmation.
+
+**Jamie:** What should happen before anyone copies and runs it?
+
+**Alex:** Do not treat Option 2: Use Claude Code for Faster Iteration as decoration. Claude Code runs on the command line and offers free tier access (for certain Claude models). That is not trivia. Full setup: See Appendix AA: Installation & Setup - Claude Code.
+
+**Alex:** Here is the part to remember. You want to test agents without VS Code. You prefer terminal workflows. You want quick command-line experimentation.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @anthropic-ai/claude-code; claude code auth; claude code @daily-briefing morning briefing. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
 ---
 
+**Jamie:** How do you keep commands from becoming magic words?
+
+**Alex:** If the interface shifts, Option 3: Use Gemini CLI for Free Accessibility is still useful because gemini CLI offers free tier access to Gemini models with built-in Google Search. For someone navigating by keyboard or screen reader, this detail matters: Full setup: See Appendix AA: Installation & Setup - Gemini CLI.
+
+**Alex:** Here is the part to remember. Budget is a priority. You want Google Search integrated with agent responses. You prefer lightweight CLI tools.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @google/gemini-cli; gemini config set api-key YOUR API KEY Get free key at ai.google.dev; gemini @daily-briefing morning briefing. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Alex:** Keep the teaching thread moving. Put Option 4: Use Claude Desktop for Long Sessions into plain language. Claude Desktop is the native Claude application with extended context windows and offline capability. The useful version is: Full setup: See Appendix AA: Installation & Setup - Claude Desktop. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+
+**Alex:** Here is the part to remember. Working on large documents or codebases. Need longer conversation context (200K tokens+). Offline work on the plane. MCP server integration for custom tools.
+
+**Jamie:** Let's pause on Choosing Your Primary Platform. What should a learner take away from it?
+
+**Alex:** Choosing Your Primary Platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Yes → Use GitHub Copilot (VS Code) - it's already there. No → Continue to 2. Yes → Use Claude Desktop for longer sessions or Claude Code for CLI. No → Continue to 3. CLI → Use Gemini CLI (free) or Claude Code. GUI → Use Claude Desktop.
+
+**Alex:** Think of this as 4 checks: Do you already use VS Code daily?; Do you have a Copilot or Claude subscription?; Do you prefer CLI or GUI?; and Are you exploring experimental features? Each step should leave a trace you can name.
+
+---
+
+**Jamie:** What is the safe way to learn from that example?
+
+**Alex:** This part earns its place because all agents work the same across platforms, but the workflow differs slightly. That gives the learner a foothold: example: Run @aria-specialist on all five platforms.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Ctrl+Alt+I → Type: @aria-specialist audit this component for ARIA. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Path A: "I use VS Code" (Recommended). What should a learner take away from it?
+
+**Alex:** Path A: "I use VS Code" (Recommended) has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** First, install Copilot extension (automatic). Then, complete all challenges in Section 4 using Copilot Chat. After that, optionally try Claude Desktop for longer sessions. Finally, explore Appendices AA, AB, AC for advanced features. That is the rhythm: orient, act, verify, continue.
+
+**Jamie:** Let's pause on Path B: "I prefer command line". What should a learner take away from it?
+
+**Alex:** Path B: "I prefer command line" has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Start here: Install Claude Code CLI: npm install -g @anthropic-ai/claude-code. Then: Run agents from terminal. Next: Use Gemini CLI for free tier experimentation. Last: Refer to Appendix AB for hooks and scripting. That small check between steps is what makes the workflow reliable.
+
+---
+
+**Jamie:** Let's pause on Path C: "I want the best of both". What should a learner take away from it?
+
+**Alex:** Path C: "I want the best of both" has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Walk it in order: Use Copilot in VS Code for daily work; Install Claude Desktop for long-context projects; Keep Gemini CLI for quick experiments; and Switch between platforms as needed per task. The sequence works because every action has a confirmation.
+
+**Alex:** Keep the teaching thread moving. Screen Reader, Low Vision, and Keyboard Navigation by Platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part to remember. Screen readers: Full support in Chat panel; use Ctrl+Alt+I to open. Low vision: Zoom independently with Ctrl+=; use High Contrast theme. Keyboard: Full keyboard navigation; all features accessible. Screen readers: Full terminal support (NVDA, JAWS announce all output). Low vision: Terminal zoom and colors configurable. Keyboard: Native CLI keyboard support.
+
+**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
+
+**Jamie:** Let's pause on Next Steps. What should a learner take away from it?
+
+**Alex:** The reason this matters is simple: choose your primary platform and continue with the challenges in Section 4. The listener should be able to check this: You can switch platforms anytime - all agents work the same way.
+
+**Alex:** Here is the part to remember. Already in VS Code? Go to Section 4 now. Want to try CLI first? Read Appendix AA: Installation then come back to Section 4. Want full platform comparison? See Appendix K: Copilot Reference for detailed feature matrix.

Slash commands are defined in.github/prompts/ as.prompt.md files -- open them in the Explorer to read what each command does before using it. Create your own command by copying an existing.prompt.md file, renaming it, and editing the instructions -- no code required. The / command menu appears as a dropdown list in Copilot Chat -- it scales with VS Code's font and zoom settings. Each command has a short description visible in the dropdown; use Ctrl+= to zoom if the text is too small. Open the.prompt.md file in the editor to read the full command definition at your preferred zoom level.

 **Alex:** Here is the part to remember. Agent.agent.md files use YAML frontmatter at the top (between --- delimiters) followed by Markdown body; in VS Code, use Ctrl+G to jump to line 1 and arrow through the frontmatter fields (name, description, tools) before reading the body instructions. When writing your own.agent.md, use VS Code's Outline view (Ctrl+Shift+O) to verify that your Markdown headings (Purpose, Capabilities, Responsibilities) are correctly nested -- malformed headings will not appear in the outline. Before submitting a PR with a new agent file, run the file through a YAML linter (install the YAML extension, or use yamllint from the terminal) -- frontmatter syntax errors silently break agent registration. YAML frontmatter fields are densely packed with colons and quotes; increase your editor font size or use a monospaced font with wide character spacing so name:, description:, and tools: are clearly distinct. The.agent.md files in the agents/ directory follow a consistent structure -- use the file explorer's icon theme or file nesting feature to visually group agent files separately from regular documentation. When reviewing existing agents for contribution ideas, use VS Code's split editor to place the agent file and the README side by side so you can cross-reference the agent's instructions with its documented capabilities.

 **Alex:** Here is the part to remember. GitHub Desktop is a native application -- on Windows it uses UI Automation, not a browser DOM; your screen reader's object navigation (NVDA: Insert+Numpad) rather than browse mode is the correct approach for navigating its interface. GitHub CLI (gh) is entirely terminal-based; all output is plain text that your screen reader reads line by line -- pipe verbose output through head -20 or Select-Object -First 20 to avoid overwhelming your speech buffer. Copilot CLI (gh copilot suggest and gh copilot explain) presents interactive prompts in the terminal; listen for the "Run this command? (Y/n)" confirmation before pressing Enter to avoid executing unreviewed commands. GitHub Desktop inherits your Windows display scaling -- if text appears small, increase system-level scaling (Settings Display Scale) rather than looking for an in-app zoom option. Terminal output from gh and gh copilot uses your terminal's font and color settings; configure your terminal profile (Windows Terminal settings or iTerm2 preferences) with a high-contrast color scheme and large font for comfortable reading. Copilot CLI suggestions appear as plain text in the terminal, not in a styled panel -- they are easy to miss among other output; look for the indented suggestion block immediately after your prompt.

After that, at the top, you see "Copilot Chat" and probably a text input at the bottom saying "Ask Copilot.". Finally, click in the chat input box (bottom of Copilot Chat panel). Keep it that plain: know where you are, make the move, check the result.

-**Alex:** If the interface shifts, What you're adding is still useful because if the agent doesn't recognize your new workflow.
+**Alex:** Here is the learner-facing version. If the agent doesn't recognize your new workflow.
 
 **Alex:** Here is the part to remember. A clear label for the new workflow. Instructions on how to invoke it. Pre-defined fields that make sense for security reports. Specific options for severity and vulnerability type. The agent recognizes your new workflow. Next time you invoke @template-builder with "create security template", it will follow your new guidance.
 
-**Alex:** Start here: Save the file: Ctrl+S. Then: You should see no error messages. Next: The agent file now includes your new Pre-Built Workflow. Last: Open Copilot Chat again: Ctrl+Alt+I, or run Chat: Open Chat from the Command Palette. Pause after each step and listen for the confirmation before moving on.

 **Jamie:** Let's pause on Exercise 3: Iterative Refinement with Agents. What should a learner take away from it?
 
-**Alex:** Put Exercise 3: Iterative Refinement with Agents into plain language. Your Mission: Generate a template, then ask the agent to modify it incrementally. The useful version is: This teaches you the iterative pattern that scales to all agent-assisted workflows. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** This is the move inside Exercise 3: Iterative Refinement with Agents: your Mission: Generate a template, then ask the agent to modify it incrementally. That matters in practice: This teaches you the iterative pattern that scales to all agent-assisted workflows.
 
 **Alex:** Here is the part to remember. Running a complete template generation (same as Exercise 1). The agent modifies the YAML it generated. The new checkbox appears in the YAML with proper formatting and indentation. It doesn't regenerate from scratch - just adds your change.
 
-**Alex:** Walk it in order: In Copilot Chat, type: @template-builder create a feature request template; Answer the agent's questions to build a feature request form; Let the agent generate the YAML; and Copy it to a file.github/ISSUE TEMPLATE/feature-request.yml. The point is not speed; the point is never losing your place.

That is the difference between guessing and knowing: That is Accessibility Agents' promise: not to replace your thinking, but to amplify your skills across all 55 agents - and to grow through the contributions of everyone who uses it.
+**Alex:** Anchor this part on What Comes Next. Your next step: explore the broader ecosystem. This is the part to say slowly: That is Accessibility Agents' promise: not to replace your thinking, but to amplify your skills across all 55 agents - and to grow through the contributions of everyone who uses it. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
 
 **Alex:** Here is the part to remember. Browse the full agent list - which agents solve problems you face regularly? Try an Accessibility team agent: @contrast-master check this page or @alt-text-headings review this file. Try a Developer Tools agent: @python-specialist review this module for accessibility or @desktop-a11y-specialist audit this dialog. Think about what is missing: what agent would you build if you could?
 
-**Alex:** Think of this as 3 checks: Generated a template using an agent (Exercise 1); Customized an agent for your domain (Exercise 2); and Refined iteratively with agent help (Exercise 3). Each step should leave a trace you can name.

+
+**Alex:** Learning Cards: Contributing to the Ecosystem has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
 **Alex:** Here is the part to remember. Agent.agent.md files use YAML frontmatter at the top (between --- delimiters) followed by Markdown body; in VS Code, use Ctrl+G to jump to line 1 and arrow through the frontmatter fields (name, description, tools) before reading the body instructions. When writing your own.agent.md, use VS Code's Outline view (Ctrl+Shift+O) to verify that your Markdown headings (Purpose, Capabilities, Responsibilities) are correctly nested -- malformed headings will not appear in the outline. Before submitting a PR with a new agent file, run the file through a YAML linter (install the YAML extension, or use yamllint from the terminal) -- frontmatter syntax errors silently break agent registration. YAML frontmatter fields are densely packed with colons and quotes; increase your editor font size or use a monospaced font with wide character spacing so name:, description:, and tools: are clearly distinct. The.agent.md files in the agents/ directory follow a consistent structure -- use the file explorer's icon theme or file nesting feature to visually group agent files separately from regular documentation. When reviewing existing agents for contribution ideas, use VS Code's split editor to place the agent file and the README side by side so you can cross-reference the agent's instructions with its documented capabilities.

+**Alex:** If the interface shifts, How the Three Teams Connect is still useful because in practice, a single task often spans multiple teams. For someone navigating by keyboard or screen reader, this detail matters: No single agent covers the entire workflow.
 
 **Alex:** Here is the part to remember. You ask @daily-briefing (GitHub Workflow) for your morning report. It flags a PR that changes ARIA attributes. You ask @pr-review (GitHub Workflow) to generate a structured review of that PR. The review notes potential accessibility impact. You invoke @aria-specialist (Accessibility) to deep-check the ARIA changes. It identifies a missing aria-expanded state on a disclosure widget. You fix the issue using patterns from @desktop-a11y-specialist (Developer Tools) if it is a desktop application, or directly in the HTML if it is a web project.

 **Alex:** Here is the part to remember. Orchestrator agents like @accessibility-lead coordinate multi-agent workflows -- invoke one and it delegates to specialists, announcing which agent it is calling. Multi-agent output appears in sequence in Copilot Chat -- press Alt+F2 after each response to read it in Accessible View before the next agent responds. The three teams are GitHub Workflow (what happened), Accessibility (is it correct), and Developer Tools (fix it) -- choose your entry point based on your current task. Orchestrator responses can be long -- use Accessible View (Alt+F2) or widen the Chat panel to read comfortably at high zoom. The workflow diagrams in this section are described in text -- no visual-only content is required to understand the agent coordination pattern. Each team's agents are listed in the tables in Section 3 -- refer back there to find the right specialist agent.
 
-**Alex:** Keep the teaching thread moving. Anchor this part on Orchestrator Agents. Four agents are specifically designed to coordinate others. This is the part to say slowly: You do not need to use orchestrators to get value from individual agents.

 **Jamie:** Before we leave Solutions, what is the practical point?
 
-**Alex:** First, provide more context in your prompt: Be specific about what you need. Then, use @ mentions: Reference specific files or selections (@filename.md, selection). After that, check the agent's prerequisites: Did you do the manual work first? Finally, review the agent's instructions: Open.github/agents/[name].agent.md and read what it's supposed to do. That small check between steps is what makes the workflow reliable.

-**Jamie:** Let's pause on Slash command doesn't work. What should a learner take away from it?
-
-**Alex:** If the interface shifts, Slash command doesn't work is still useful because issue: /command shows "Command not found.".
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Issue: /command shows "Command not found.". A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
 **Jamie:** What is the teaching move inside Solutions?
 
-**Alex:** Put Solutions into plain language. Next: Chapter 20: Build Your Agent Back: Chapter 18: Fork and Contribute Related appendices: Appendix L: Agents Reference Appendix K: Copilot Reference.
+**Alex:** This is the move inside Solutions: next: Chapter 20: Build Your Agent Back: Chapter 18: Fork and Contribute Related appendices: Appendix L: Agents Reference Appendix K: Copilot Reference.
 
-**Alex:** Walk it in order: Verify.github/prompts/[name].md exists; Reload window: Ctrl+Shift+P → "Reload Window"; Check file naming: must be a.md file in.github/prompts/; and Try typing the full command name (autocomplete may be incomplete). Keep it that plain: know where you are, make the move, check the result.

The sequence works because every action has a confirmation.
 
-**Jamie:** Let's pause on 1. The Capstone Challenge. What should a learner take away from it?
+**Jamie:** Let's pause on 1. The Capstone Project. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. The capstone is Challenge 16 -- the final challenge of the workshop. That is the difference between guessing and knowing: Your pull request goes to a real repository.
+**Alex:** Anchor this part on 1. The Capstone Project. The capstone is bigger than one challenge and bigger than one repository. This is the part to say slowly: Challenge 16 is the checkpoint where you show evidence.
 
-**Alex:** Think of this as 4 checks: Choose a mission for a new accessibility agent (or improve an existing one); Write an agent file with valid YAML frontmatter; Define clear responsibilities and guardrails; and Test the agent locally with GitHub Copilot. Pause after each step and listen for the confirmation before moving on.
+**Alex:** Think of this as 4 checks: Choose a repository where an agentic contribution would be useful; Identify a real audience and a real workflow gap; Create or improve an agent, prompt, custom instruction, skill, workflow, or documentation page that helps that repository; and Define clear responsibilities and guardrails. Keep it that plain: know where you are, make the move, check the result.

+**Jamie:** Before we leave 1. The Capstone Project, what is the practical point?
 
-**Alex:** The path is straightforward once it is named. Step one is open a pull request from your fork to the upstream repository. Step two is respond to peer review feedback. The point is not speed; the point is never losing your place.
+**Alex:** The path is straightforward once it is named. Step one is test the contribution locally or document how it should be tested. Step two is open a pull request, prepare a review-ready branch, or write a contribution plan when you do not have repository access. Step three is respond to review or describe what review feedback you would seek. Pause after each step and listen for the confirmation before moving on.

-**Alex:** Keep the teaching thread moving. What you need before starting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here is the part to remember. [ ] You have forked and cloned the accessibility-agents repository (Chapter 18). [ ] You have a feature branch created: agents/your-username-agent-name. [ ] You understand how to push to your fork and open a PR (Chapter 18). [ ] You have GitHub Copilot or Copilot Free active (Chapter 16). [ ] You have explored the existing agents in Chapter 19.
+**Jamie:** Let's pause on What Counts as a Capstone Contribution. What should a learner take away from it?
 
-**Jamie:** Let's pause on Time estimate. What should a learner take away from it?
+**Alex:** The reason this matters is simple: the following table lists valid capstone contribution types.
 
-**Alex:** Time estimate: Most students complete the capstone in 60 to 90 minutes. The next useful detail is concrete: The phases are designed so you can get a working agent in 30 minutes and spend the remaining time improving it.
+**Alex:** Keep the teaching thread moving. What You Need Before Starting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. See also: Chapter 19: Accessibility Agents introduces the agent ecosystem and shows existing agents for inspiration.

+**Alex:** Here is the part to remember. [ ] You understand the fork, branch, commit, push, and PR workflow from Chapter 18. [ ] You have GitHub Copilot or Copilot Free active from Chapter 16. [ ] You have explored Accessibility Agents in Chapter 19, even if you choose a different capstone repository. [ ] You know which repository you want to help and why. [ ] You can explain the impact of your contribution in one or two sentences.
 
-**Jamie:** Let's pause on What makes a good agent mission. What should a learner take away from it?
+**Jamie:** Let's pause on Time Estimate. What should a learner take away from it?
 
-**Alex:** This is the move inside What makes a good agent mission: a good agent solves a specific, recurring problem.
+**Alex:** If the interface shifts, Time Estimate is still useful because most students complete a workshop-ready capstone in 60 to 90 minutes. For someone navigating by keyboard or screen reader, this detail matters: A polished pull request can take longer, especially when the target project has tests, review requirements, or unfamiliar architecture.
 
-**Alex:** Here is the part to remember. What task do you repeat? Think about workflow steps from Day 1 and Day 2 that felt repetitive. What would a specialist know? An agent works best when it has deep knowledge of a focused area. What gap exists? Look at the existing agents in Chapter 19. Is there a workflow that no agent covers?
-
-**Alex:** Keep the teaching thread moving. Anchor this part on Write your mission statement. Before writing any code, write a one-sentence mission statement. This is the part to say slowly: "My agent helps [who] by [doing what] when [in what situation].". The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
-
-**Jamie:** Let's pause on 3. Phase 2: Write the Agent File. What should a learner take away from it?
+---
 
-**Alex:** The reason this matters is simple: an agent file is a Markdown file with YAML frontmatter that defines the agent's identity, and a body that contains the agent's instructions. The listener should be able to check this: Agent files live in the.github/agents/ directory (for GitHub Copilot agents) or in team-specific directories in the accessibility-agents repository.
+**Jamie:** What is the judgment call here?
 
----
+**Alex:** Put 2. Choose Your Contribution Path into plain language. Choose a repository where your work can be genuinely useful. The useful version is: The following table compares the recommended paths.
 
-**Alex:** Keep the teaching thread moving. Do not treat File location and naming as decoration. Example.github/agents/alt-text-validator.md.
+**Alex:** Use the comparison to make a decision, not to recite a table. The main contrasts are: Best For means Good Contribution Ideas. Accessibility Agents means Learners who want the most direct agent-building path means Add a focused agent, improve guardrails, update docs, refine prompts, improve skills. Learners interested in document accessibility, large print, Office files, web apps, desktop apps, or user workflows means Add a GLOW-focused agent, improve.github customizations, document contributor workflows, propose rule coverage.
 
-**Jamie:** Let's pause on The agent file structure. What should a learner take away from it?
+**Jamie:** Let's pause on Choosing Well. What should a learner take away from it?
 
-**Alex:** The agent file structure has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** The teaching point here is not the label; it is the move. Ask these questions before you choose.
 
-**Alex:** Start here: YAML frontmatter -- metadata between --- markers at the top of the file. Then: Instructions body -- Markdown content that tells the agent how to behave. Pause after each step and listen for the confirmation before moving on.
+**Alex:** Here is the part to remember. Impact: Who would benefit if this contribution were merged? Fit: Does the repository already use agents, prompts, instructions, skills, or automation? Scope: Can you make a useful change in one small pull request? Access: Can you fork the repository or create a draft in your own fork? Safety: Can you define guardrails that prevent the agent from overreaching?
 
-**Alex:** Keep the teaching thread moving. Put YAML frontmatter fields into plain language. Vague descriptions result in missed automatic routing. The useful version is: Weak: Helps with accessibility - Strong: Checks markdown files for accessibility issues, fixes descriptive links and heading hierarchy, and flags alt text for human review The more specific the description, the more reliably Copilot invokes the right agent for. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** Keep the teaching thread moving. This part earns its place because accessibility Agents is the default capstone path because it is built around agents, prompts, instructions, skills, and accessibility workflows. That gives the learner a foothold: current local inventory checked May 13, 2026. That is the difference between following directions and owning the workflow.

-**Jamie:** Let's pause on Writing the instructions body. What should a learner take away from it?
+**Jamie:** Let's pause on Why Choose Accessibility Agents. What should a learner take away from it?
 
-**Alex:** The teaching point here is not the label; it is the move. The instructions body tells the agent how to behave. That is the difference between guessing and knowing: Write it as if you are briefing a new team member on their first day.
+**Alex:** Why Choose Accessibility Agents has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. Start with identity. "You are a [role] focused on [area].". List responsibilities. What specific tasks does this agent handle? Set guardrails. What should the agent never do? What are its limits? Provide examples. Show what good output looks like.
+**Alex:** Here is the part to remember. You want to build or improve an actual agent. You want clear examples to copy and adapt. You want your contribution to help accessibility reviewers, developers, document remediators, GitHub maintainers, or assistive technology users. You want the Challenge 16 autograder path that validates agent frontmatter, responsibilities, and guardrails.
 
-**Alex:** Keep the teaching thread moving. Learning Cards: Writing the Agent File has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. Good Accessibility Agents Contributions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. Create your agent file with Ctrl+N, then Ctrl+S and save to.github/agents/your-agent-name.md -- the Explorer navigates to the folder automatically. Use Ctrl+Shift+O to navigate between YAML frontmatter fields and Markdown headings (Responsibilities, Guardrails) in your agent file. The YAML frontmatter is between --- markers at the top -- your screen reader announces these as horizontal rules. Agent files are standard Markdown -- open Markdown Preview (Ctrl+Shift+V) side by side to verify formatting as you write. The YAML frontmatter at the top uses name: and description: fields -- keep these on separate lines for readability at high zoom. Use a consistent heading hierarchy ( for title, for sections) so the Outline view (Ctrl+Shift+O) shows a clean structure.
+**Alex:** Here is the part to remember. Add a small specialist agent for an uncovered accessibility workflow. Improve an existing agent's guardrails or output format. Update stale counts, platform names, or release-note guidance in documentation. Add examples that show how screen reader, low vision, keyboard-only, and sighted users should use an agent. Improve prompt files so they produce more structured, reviewable output. Improve a skill reference with clearer severity scoring or remediation guidance.
 
-**Jamie:** Let's pause on 4. Phase 3: Define Responsibilities and Guardrails. What should a learner take away from it?
+**Jamie:** Let's pause on 4. Project Option: GLOW. What should a learner take away from it?
 
-**Alex:** 4. Phase 3: Define Responsibilities and Guardrails: Responsibilities and guardrails are the most important parts of your agent's instructions. The next useful detail is concrete: The autograder checks that both sections exist.
+**Alex:** This is the move inside 4. Project Option: GLOW: gLOW stands for Guided Layout & Output Workflow. That matters in practice: It is a multi-surface accessibility toolkit for auditing, fixing, converting, and generating accessible documents.
 
 ---
 
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Responsibilities define what the agent does. Put another way, each responsibility should describe one discrete action the agent can take. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Alex:** Keep the teaching thread moving. What GLOW Does has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. Scan HTML files for tags missing the alt attribute. Check that all elements have visible text or an aria-label. Verify heading levels do not skip (e.g., h1 to h3 without h2). Help with accessibility.
+**Alex:** Here is the part to remember. Audits Word, Excel, PowerPoint, Markdown, PDF, EPUB, HTML, and CSS for accessibility issues. Auto-fixes Word document issues where the change is deterministic, such as fonts, spacing, emphasis, headings, and margins. Generates ACB-compliant Word templates. Converts documents to Markdown, accessible HTML, Word, EPUB 3, PDF, and DAISY-oriented outputs through MarkItDown, Pandoc, LibreOffice, and related tooling. Provides web, desktop, CLI, VS Code, and Word add-in surfaces. Supports standards profiles such as ACB 2025 Baseline, APH Submission, and Combined Strict.
 
-**Jamie:** Let's pause on Writing guardrails. What should a learner take away from it?
+**Jamie:** Let's pause on Why Choose GLOW. What should a learner take away from it?
 
-**Alex:** This is the move inside Writing guardrails: guardrails define what the agent must not do. That matters in practice: They prevent the agent from overstepping, giving harmful advice, or acting without permission.
+**Alex:** Why Choose GLOW has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. Never auto-fix code without asking the user first. Do not provide medical, legal, or financial advice when discussing accessibility compliance. Limit reviews to the files the user specifies -- do not scan the entire repository. If a finding is uncertain, say so explicitly rather than presenting it as definitive.
+**Alex:** Here is the part to remember. You care about documents, large print, Office files, or accessible publishing. You want a smaller agent surface where one contribution can make a visible difference. You want to connect agents to a real product workflow: upload, audit, fix, convert, template, export, review. You want to help users who may not think of themselves as developers.
 
-**Alex:** Keep the teaching thread moving. Learning Cards: Responsibilities and Guardrails has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. Good GLOW Contributions has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Here is the part to remember. Use Responsibilities and Guardrails as exact heading names -- the autograder searches for these strings. Each responsibility should start with a verb (Scan, Check, Verify, Flag) -- this makes them concrete and testable. Guardrails should start with "Never" or "Do not" to set clear boundaries your screen reader identifies as restrictions when reviewing the file. Format responsibilities as a bulleted list (starting with -) for easy scanning at high zoom -- one responsibility per bullet. Keep each guardrail to a single line so it remains visible without horizontal scrolling at your zoom level. Use bold text for emphasis on critical guardrails (e.g., Never modify files without approval ) to improve visual scanning.
+**Alex:** Here is the part to remember. Add a GLOW agent that helps users choose between Audit, Fix, Template, Export, and Convert workflows. Improve the existing large-print agent instructions with clearer responsibilities and guardrails. Add a prompt for reviewing release notes against current GLOW features. Add custom instructions for web UI accessibility, plain-language findings, or large-print documentation consistency. Write documentation that explains how contributors should test document accessibility changes. Draft an issue for a future agent, such as a plain-language findings reviewer, batch-audit triage assistant, or Word add-in accessibility reviewer.

+**Jamie:** Let's pause on GLOW Safety Notes. What should a learner take away from it?
 
-**Alex:** The reason this matters is simple: see also: Chapter 18: Fork and Contribute covers the fork-and-PR workflow you will use to submit your agent. The listener should be able to check this: Before opening a pull request, test your agent to verify it works.
+**Alex:** GLOW Safety Notes has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Let's pause on Testing with GitHub Copilot Chat. What should a learner take away from it?
+**Alex:** Here is the part to remember. GLOW handles documents that may contain personal, educational, medical, or organizational information. Do not put private user documents into public prompts or issues. Auto-fix workflows must be conservative. An agent should explain proposed fixes and preserve author intent. Large-print rules can affect pagination and layout. Document tradeoffs instead of pretending every fix is neutral. When a rule comes from ACB, APH, Microsoft Accessibility Checker, or WCAG, cite the source or name the profile.
 
-**Alex:** Testing with GitHub Copilot Chat has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Keep the teaching thread moving. Put 5. Project Option: Another Repository into plain language. You may choose another repository if the contribution is meaningful and reviewable. The useful version is: This can be your own project, a classmate's project, a community repository, or another open source project you care about. The interface gets easier when it becomes a set of named places instead of a wall of controls.
 
-**Alex:** Here is the part to remember. Understand its mission? Follow its responsibilities? Respect its guardrails?
+**Jamie:** Let's pause on Requirements for Another Repository. What should a learner take away from it?
 
-**Alex:** First, open VS Code with the accessibility-agents repository. Then, ensure your agent file is saved in.github/agents/. After that, open GitHub Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette. Finally, invoke your agent by name: @your-agent-name check this file for accessibility issues. The point is not speed; the point is never losing your place.
+**Alex:** Requirements for Another Repository has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Jamie:** Before we leave Testing with GitHub Copilot Chat, what is the practical point?
-
-**Alex:** Start here: Observe the response. Does the agent. Each step should leave a trace you can name.
-
-**Jamie:** Let's pause on Testing checklist. What should a learner take away from it?
-
-**Alex:** Testing checklist has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here is the part to remember. [ ] The agent responds when invoked by name. [ ] The agent stays within its defined responsibilities. [ ] The agent does not violate any guardrails. [ ] The agent's output is useful and specific. [ ] The agent handles edge cases gracefully (empty files, no issues found).
+**Alex:** Here is the part to remember. The work must help the repository, not just satisfy the workshop. The contribution must have a clear audience. The contribution must be small enough to review. The contribution must include responsibilities and guardrails when it involves an agent or automated workflow. If you cannot open a pull request, write a review-ready issue or contribution plan instead.

-**Jamie:** Let's pause on Iterating on your agent. What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Good Contributions in Any Repository has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Put Iterating on your agent into plain language. If the agent does not behave as expected. The useful version is: Most students iterate 2-3 times before they are satisfied.
+**Alex:** Here is the part to remember. Add.github/copilot-instructions.md that teaches Copilot the project's accessibility and contribution standards. Add a custom agent for triaging issues, reviewing docs, checking release notes, or auditing accessibility. Add a prompt file for a repeated maintainer task. Improve issue templates or PR templates so contributors provide better accessibility context. Write contributor documentation that explains how to test with keyboard, screen reader, and high contrast workflows.
 
-**Alex:** Walk it in order: Read its instructions carefully. Is anything ambiguous?; Add more specific instructions or examples; Test again with the same prompt; and Repeat until the behavior matches your intent. If one step does not match what you hear, stop there and re-orient.
+**Jamie:** Let's pause on 6. Define Your Mission. What should a learner take away from it?
 
-**Jamie:** Let's pause on Learning Cards: Testing Your Agent. What should a learner take away from it?
+**Alex:** 6. Define Your Mission: A good capstone mission solves a specific, recurring problem. The next useful detail is concrete: Write a one-sentence mission statement before editing files.
 
-**Alex:** Learning Cards: Testing Your Agent has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+**Alex:** Here is the part to remember. "My agent helps GLOW contributors by checking whether release notes describe user-facing document accessibility changes clearly.". "My prompt helps Accessibility Agents maintainers by turning a release note into repo documentation updates with screen reader, low vision, and sighted guidance.". "My custom instructions help my project avoid inaccessible React patterns when Copilot generates forms and dialogs.".
 
-**Alex:** Here is the part to remember. Open Copilot Chat (Ctrl+Alt+I) or run Chat: Open Chat from the Command Palette, then type @your-agent-name followed by a test prompt -- your screen reader announces the response as it streams. Press Alt+F2 after the response finishes to read the full output in Accessible View with arrow keys. If the agent does not respond as expected, edit the.agent.md file and ask again -- Copilot picks up changes immediately. Agent responses appear in the Copilot Chat panel -- widen the panel by dragging its left edge for better readability. Test with a simple prompt first (e.g., "review this file") and read the full response before trying complex requests. Use Accessible View (Alt+F2) to read responses at your preferred editor font size instead of the Chat panel's default.
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. Your asset may be an agent file, prompt file, instruction file, skill, or documentation update. Put another way, if you are writing an agent, use the structure below. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
 
-**Jamie:** Let's pause on Tool Cards: Open Your Capstone PR. What should a learner take away from it?
-
-**Alex:** This part earns its place because VS Code Desktop (primary for Day 2). That is the difference between following directions and owning the workflow.
+---
 
-**Alex:** The path is straightforward once it is named. Step one is push your branch: Ctrl+Shift+P Git: Push. Step two is ctrl+Shift+P GitHub Pull Requests: Create Pull Request. Step three is set base repo to Community-Access/accessibility-agents, fill in the title and description. Step four is navigate to your fork on GitHub. That small check between steps is what makes the workflow reliable.
+**Jamie:** Let's pause on Agent File Location and Naming. What should a learner take away from it?
 
-**Jamie:** Before we leave Tool Cards: Open Your Capstone PR, what is the practical point?
+**Alex:** This is the move inside Agent File Location and Naming: follow the target repository's conventions. That matters in practice: Example.github/agents/plain-language-findings.agent.md.
 
-**Alex:** First, click Contribute Open pull request. Then, verify the base is Community-Access/accessibility-agents:main and the compare is your branch. The sequence works because every action has a confirmation.
+**Alex:** Keep the teaching thread moving. Anchor this part on YAML Frontmatter Fields. The following table describes the common agent frontmatter fields.
 
-**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git push -u origin your-branch; gh pr create --repo Community-Access/accessibility-agents. Read the command, understand what it changes, then run it only when the repository state matches the lesson.

Use Ctrl+Shift+O to move by heading and confirm that Responsibilities and Guardrails are easy to find. Use Alt+F2 for long Copilot responses while testing the agent. Keep frontmatter fields on separate lines and use a consistent heading hierarchy. Use Markdown Preview to verify that headings, lists, and examples are visually clear. Avoid long single-line bullets that require horizontal scrolling at high zoom.

-**Alex:** Keep the teaching thread moving. Learning Cards: Opening Your Pull Request has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here is the part to remember. The autograder comment appears in the PR timeline -- navigate to Comments on GitHub.com with h (heading navigation) to find the results. Each autograder check is listed with a pass/fail status and point value -- listen for "10/10" or "0/15" to identify which checks need attention. If a check fails, read the failure message, fix the issue locally, commit, push, and the autograder re-runs automatically. The autograder results appear as a comment with a table showing checks, points, and pass/fail status -- zoom with Ctrl+= to read the details.

+**Jamie:** Before we leave Tool Cards: Open Your Capstone PR, what is the practical point?
 
-**Jamie:** Let's pause on Responding to feedback. What should a learner take away from it?
+**Alex:** The path is straightforward once it is named. Step one is navigate to your fork on GitHub. Step two is activate Contribute then Open pull request. Step three is verify the base repository and compare branch. Step four is create the pull request. The point is not speed; the point is never losing your place.
 
-**Alex:** If the interface shifts, Responding to feedback is still useful because this is the same process from Chapter 18, Step 8.
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like git push -u origin your-branch; gh pr create --repo OWNER/REPOSITORY. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
 
-**Alex:** Start here: Read each review comment. Then: Make changes locally. Next: Commit and push. The PR updates automatically. Last: Reply to each comment explaining your changes. That is the rhythm: orient, act, verify, continue.
+**Alex:** Keep the teaching thread moving. PR Description Checklist has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** Keep the teaching thread moving. Put When your PR is merged into plain language. Your agent is now part of the accessibility-agents ecosystem. The useful version is: It is available to anyone who uses the repository. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+**Alex:** Here is the part to remember. [ ] Mission statement. [ ] Repository path chosen: Accessibility Agents, GLOW, or another project. [ ] What changed. [ ] Why it matters. [ ] How you tested it. [ ] Known limitations or follow-up ideas.
 
-**Alex:** Here is the part to remember. You can navigate the fork workflow end to end. You can write clear, structured technical documentation. You understand accessibility concepts well enough to teach an AI agent about them. You can respond constructively to code review.
+**Jamie:** Why is the evidence prompt part of the teaching, not just grading?
 
-**Jamie:** Let's pause on 8. Capstone Rubric. What should a learner take away from it?
+**Alex:** Challenge 16 Evidence: Post one of these in your Challenge 16 issue. The next useful detail is concrete: If you use the Accessibility Agents autograder path, it checks agent file structure in agents/ or community-agents/: frontmatter, responsibilities, and guardrails.
 
-**Alex:** The teaching point here is not the label; it is the move. The capstone is worth 60 autograded points plus peer review.
+**Alex:** Here is the part to remember. A pull request link. A branch link with the changed file. A draft agent file pasted or linked. A contribution plan with mission, responsibilities, guardrails, and target repository.

-**Alex:** Keep the teaching thread moving. This part earns its place because a capstone that meets expectations has.
+**Alex:** Keep the teaching thread moving. Here is the learner-facing version. After you submit or share your capstone, a buddy, facilitator, or maintainer may review it. Put another way, respond to review one comment at a time.

+**Alex:** Here is the part to remember. Clarity: Can someone understand the contribution in 10 seconds? Specificity: Are responsibilities concrete and actionable? Safety: Do guardrails prevent harmful or overconfident behavior? Usefulness: Would this help a real user or maintainer?
 
-**Jamie:** Let's pause on What "exceeds expectations" looks like. What should a learner take away from it?
+**Jamie:** Let's pause on 11. Capstone Rubric. What should a learner take away from it?
 
-**Alex:** What "exceeds expectations" looks like: A capstone that exceeds expectations also has.
+**Alex:** This is the move inside 11. Capstone Rubric: the capstone is assessed as a real contribution, not just as a file format exercise.
 
-**Alex:** Here is the part to remember. Examples of expected input and output in the agent instructions. A section describing the agent's limitations. Evidence of testing (screenshots or transcripts in the PR description). Thoughtful responses to review feedback.
-
-**Alex:** Keep the teaching thread moving. Here is the learner-facing version. These examples show the range of valid agent designs. Put another way, your agent does not need to be this long, but it should be this clear. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+**Alex:** Keep the teaching thread moving. Anchor this part on Core Criteria. The following table lists the capstone evaluation criteria. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.

-**Jamie:** Let's pause on Example 1: Heading Hierarchy Checker. What should a learner take away from it?
-
-**Alex:** This is the move inside Example 1: Heading Hierarchy Checker: mission: Validates that HTML and Markdown documents follow a correct heading hierarchy (no skipped levels).
+**Jamie:** Let's pause on What Exceeds Expectations Looks Like. What should a learner take away from it?
 
-**Alex:** Here is the part to remember. Scan files for heading elements (h1 through h6 in HTML, through in Markdown). Report any instance where a heading level is skipped (e.g., h2 followed by h4). Suggest the correct heading level for each violation. Check that there is exactly one h1 per page. Do not modify files -- only report findings. Do not change heading text, only heading levels.
+**Alex:** What Exceeds Expectations Looks Like has three jobs: name the idea, give the learner a move, and show what counts as evidence.
 
-**Alex:** A solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.
-
-**Alex:** Keep the teaching thread moving. Anchor this part on Example 2: PR Description Quality Gate. Mission: Reviews pull request descriptions to ensure they contain enough context for reviewers.
-
-**Alex:** Here is the part to remember. Check that the PR description is at least 50 characters. Verify the description references an issue with Closes XX or Fixes XX. Check for a summary of changes made. Verify the description explains why the change was made, not just what was changed. Never approve or block a PR based solely on description quality. Do not rewrite the description for the author -- suggest improvements.
+**Alex:** Here is the part to remember. The contribution includes examples of expected input and output. The PR description explains tradeoffs and limitations. The learner tests with Copilot Chat or the VS Code Agents window and documents the result. The learner responds thoughtfully to review feedback. The contribution improves existing documentation, counts, or setup instructions alongside the agentic asset.
 
-**Jamie:** Let's pause on Example 3: Keyboard Navigation Auditor. What should a learner take away from it?
+**Alex:** Keep the teaching thread moving. Do not treat 12. If You Get Stuck as decoration. The following table lists common capstone blockers and recovery steps.
 
-**Alex:** The reason this matters is simple: mission: Checks web components for keyboard accessibility compliance.
+**Jamie:** Let's pause on The Universal Safety Net. What should a learner take away from it?
 
-**Alex:** Here is the part to remember. Verify all interactive elements are reachable via Tab key. Check that custom components have appropriate tabindex values. Validate that focus order follows visual layout. Detect keyboard traps (elements that receive focus but cannot release it via keyboard). Do not modify component code without user approval. Flag potential issues with confidence levels (certain, likely, possible).
-

-
-**Alex:** Keep the teaching thread moving. Do not treat The universal safety net as decoration. If everything else fails, post this on your challenge issue. That is not trivia. I attempted Challenge 16 and here is what happened: What I tried: [specific actions] What I expected: [what should have happened] What actually happened: [error or unexpected result] What I learned: [even from failure, what do I understand now?]. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.

+
+#### Transcript
+
+**Alex:** Welcome back to Git Going with GitHub. This is GitHub Accessibility and Open Source at Scale. I am Alex, and today we are turning GitHub Accessibility and Open Source at Scale from a list of instructions into a working mental model.
+
+**Jamie:** And I am Jamie. I will stop us whenever the instructions sound simple on paper but might feel different with a keyboard and screen reader.
+
+---
+
+**Alex:** How GitHub frames accessibility as part of developer belonging, product quality, customer practice, and open source contribution. That is the surface description. Underneath it, we are building judgment: where to focus, what to ignore, and how to verify the result.
+
+**Jamie:** So we are not using the audio as a shortcut around learning. We are using it to make the learning easier to enter.
+
+**Alex:** Yes. A good audio lesson gives someone enough context to try the work with confidence, even before they open the written material.
+
+---
+
+**Jamie:** Okay, set the room for us. What are we walking into?
+
+**Alex:** Why This Episode Exists: After the capstone, learners have done more than complete a classroom exercise. The next useful detail is concrete: They have practiced the same evidence habits that make accessibility work credible in public projects: name the user, describe the barrier or opportunity, propose a focused change, test or explain the result, and invite review.
+
+**Alex:** The next layer is this. Here is the learner-facing version. GitHub describes four strategic accessibility priorities. Put another way, the following list summarizes the priorities named on GitHub Accessibility and how they connect to this workshop. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Alex:** Here are the anchors worth keeping. Employees with disabilities: GitHub says accessibility starts at home by supporting employees with disabilities, requiring accessibility training, improving internal tools and systems, and supporting employee communities such as NeuroCats and AccessCats. Developers with disabilities: GitHub says every developer should feel welcome and be able to use GitHub products, documentation, training, support, events, and community spaces. GitHub names accessibility as a GitHub Fundamental, with expectations, testing,. Customers building on GitHub: GitHub shares tools and practices that help customers meet accessibility goals, including the Figma annotation toolkit, the GitHub Accessibility Scanner action, and guidance for accessibility-focused Copilot custom instructions. Open source at scale: GitHub has pledged to help improve accessibility in open source by empowering people with disabilities to contribute, increasing free and open source assistive technologies, and increasing the accessibility of mainstream open source.
+
+**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
+
+**Alex:** This is the move inside What Excellence Looks Like In Practice: GitHub's public materials describe accessibility excellence as a system, not a slogan. That matters in practice: For learners, the lesson is practical: accessibility work is strongest when it is specific, testable, and connected to accountability.
+
+**Alex:** That shows up in the workshop in a few specific ways. defining expectations clearly. testing against those expectations. assigning accountability through scorecards. using the Primer Design System as an accessibility foundation.
+
+**Jamie:** That feels much more doable when you say it as one move.
+
+**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+
+---
+
+**Alex:** Now bring the learner back to the room. Anchor this part on Resources Learners Can Use Next. GitHub Accessibility gives learners several concrete paths after the workshop.
+
+**Jamie:** What would you say to someone who is already bracing for this to be too much?
+
+**Alex:** The reason this matters is simple: GitHub Accessibility Documentation includes developer guides and screen reader guides. The listener should be able to check this: The screen reader guide topics include Git, GitHub CLI, Copilot CLI, GitHub Copilot for Visual Studio Code, issues, pull requests, and repositories.
+
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+
+**Alex:** That matters because of the next idea. Do not treat Feedback Channels as decoration. GitHub Accessibility Feedback points users to several feedback paths. That is not trivia. This gives learners a next step when they find a real barrier: document what happened, explain the impact, and send it to the right channel. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+
+**Alex:** On the ground, that means a few things. Accessibility Community Discussion for conversations about making GitHub more usable. GitHub's Accessibility Discussion Panel for customers with disabilities who want to participate in compensated studies. GitHub Enterprise Accessibility Advisory Panel for accessibility leaders from enterprise customer organizations. GitHub Support for account-specific troubleshooting.
+
+---
+
+**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
+
+**Alex:** If the interface shifts, Conformance Reports is still useful because GitHub Accessibility Conformance Reports are based on the WCAG edition of VPAT version 2.5. For someone navigating by keyboard or screen reader, this detail matters: The reports cover many GitHub products and surfaces, including GitHub.com, GitHub CLI, GitHub Desktop, GitHub Classroom, GitHub Copilot, GitHub Docs, GitHub Skills, GitHub Support, GitHub mobile apps, Gists, npm CLI, and npm websites.
+
+**Alex:** This is where the talk moves from concept to action. Put Accessibility-Focused Copilot Instructions into plain language. GitHub's guide to Copilot custom instructions recommends making accessibility guidance specific to the team, repository, standards, tools, and workflows. The useful version is: It recommends clear normative language such as MUST, MUST NOT, SHOULD, and SHOULD NOT.
+
+**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+
+**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+
+**Jamie:** Turn that into a path someone can follow.
+
+**Alex:** The teaching point here is not the label; it is the move. In 2025, GitHub took the Global Accessibility Awareness Day pledge to help improve accessibility in open source software at scale. That is the difference between guessing and knowing: GitHub's strategy includes improving the platform, building partnerships, and supporting open source communities.
+
+**Alex:** Think of this as 3 checks: Empower people with disabilities to contribute to open source; Increase the availability and adoption of free and open source assistive technologies; and Increase the accessibility of mainstream open source projects. Pause after each step and listen for the confirmation before moving on.
+
+---
+
+**Alex:** Before the learner moves on. This part earns its place because the capstone asks learners to prepare an agentic contribution for Accessibility Agents, GLOW, or another meaningful repository. That gives the learner a foothold: this episode explains why that practice belongs in a larger ecosystem. That is the difference between following directions and owning the workflow.
+
+**Alex:** That becomes easier when you listen for these cues. Advanced Git Operations helps when you need recovery tools. Git Security for Contributors helps before you publish code or configuration. GitHub Desktop helps when a visual Git workflow is the right fit. GitHub CLI Reference helps when repeatable command-line workflows are useful.
+
+**Jamie:** Give me the version that sounds like an instructor, not a manual.
+
+**Alex:** Closing Message For The Episode: The listener should leave with this idea: accessibility work is not separate from software work. The next useful detail is concrete: It is part of collaboration, product quality, open source health, and developer belonging.
+
+---
+
+**Jamie:** What should people carry with them after this?
+
+**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+
+**Jamie:** That is a better way to say it than just follow the steps.
+
+**Alex:** Right. Steps matter, but understanding wins. Keep the next learning block nearby, because each part of the series keeps building the same contributor muscles.

+**Alex:** This is where confidence starts to build. Anchor this part on What Changed. The following table summarizes the 1.120 changes that affect accessible VS Code workflows. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.
+
+**Jamie:** Let's pause on Screen Reader Workflow. What should a learner take away from it?
+
+**Alex:** Screen Reader Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The path is straightforward once it is named. Step one is open the Agents window with Chat: Open Agents Window from the Command Palette. Step two is use Alt+F1 in the focused area to find context-specific accessibility help. Step three is use F6 and Shift+F6 to move among major workbench parts. Step four is use Alt+F2 for Accessible View when chat responses, terminal output, hovers, or diffs are easier to read in a stable buffer. Each step should leave a trace you can name.
+
+**Jamie:** Before we leave Screen Reader Workflow, what is the practical point?
+
+**Alex:** First, use F7 and Shift+F7 for diff navigation before accepting agent changes. Then, when terminal risk assessment is enabled, listen to the risk label and explanation, then still read the exact command before approving it. If one step does not match what you hear, stop there and re-orient.
+
+**Jamie:** Let's pause on Low Vision Workflow. What should a learner take away from it?
+
+**Alex:** Low Vision Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** First, set zoom and theme before starting a dense Agents window session. Then, use modal diff view when side-by-side changes are too compressed. After that, try Markdown preview diffs for documentation changes where rendered headings, lists, and tables are easier to inspect. Finally, widen the Sessions list, Chat area, and Changes panel as needed before reviewing work. If one step does not match what you hear, stop there and re-orient.
+
+**Jamie:** Before we leave Low Vision Workflow, what is the practical point?
+
+**Alex:** Start here: Consider separate Agents window settings if your editor and agent review layouts need different zoom or density. That is the rhythm: orient, act, verify, continue.
+
+---
+
+**Jamie:** Let's pause on Sighted Workflow. What should a learner take away from it?
+
+**Alex:** Sighted Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Start here: Use changed-file counts and session status badges as quick scope checks. Then: Open each changed file from the Changes panel before accepting a session result. Next: Use rendered Markdown diffs for documentation PRs and source diffs for syntax-sensitive edits. Last: Use the integrated browser or terminal in the Agents window to validate generated work before committing or merging. That is the rhythm: orient, act, verify, continue.
+
+**Alex:** That matters because of the next idea. Put Settings Reference into plain language. The following settings are useful to know when teaching VS Code 1.120 workflows. The useful version is: Example setting for rendered Markdown diffs. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+
+**Jamie:** So this is less about memorizing and more about noticing.
+
+**Alex:** Right. Once the learner can name the move, the interface becomes much less intimidating.
+
+---
+
 **Jamie:** What should people carry with them after this?
 
 **Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.

-
-**Alex:** Welcome back to Git Going with GitHub. This is episode 49: What Comes Next. I am Alex, and today we are turning What Comes Next from a list of instructions into a working mental model.
-
-**Jamie:** And I am Jamie. I will stop us whenever the instructions sound simple on paper but might feel different with a keyboard and screen reader.
-
----
-
-**Alex:** How to continue learning, contributing, and building confidence after the workshop. That is the surface description. Underneath it, we are building judgment: where to focus, what to ignore, and how to verify the result.
-
-**Jamie:** So we are not using the audio as a shortcut around learning. We are using it to make the learning easier to enter.
-
-**Alex:** Yes. A good audio lesson gives someone enough context to try the work with confidence, even before they open the written material.
-
----
-
-**Jamie:** Okay, set the room for us. What are we walking into?
-
-**Alex:** 1. What You Built in Two Days: Take a moment to appreciate what you accomplished. The next useful detail is concrete: This is not a list of what you were taught -- it is a list of what you did.
-
-**Alex:** The next layer is this. Day 1: You Can Navigate This has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here are the anchors worth keeping. Created and configured a GitHub account with accessibility settings. Navigated repositories, files, and folders using your screen reader, keyboard, or preferred tools. Filed issues with descriptive titles, labels, and context. Created branches, edited files, and opened pull requests. Responded to bot feedback and passed automated checks. Resolved a merge conflict.
-
-**Jamie:** What should feel predictable before the first live session starts?
-
-**Alex:** Day 2: You Can Build This has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** That shows up in the workshop in a few specific ways. Installed and configured VS Code with accessibility settings. Cloned a repository and worked with Git locally. Understood the mental model: working directory, staging area, repository. Created branches, staged changes, committed, and pushed from the command line. Explored GitHub Copilot: code suggestions, chat, and code review. Created an issue template.
-
-**Jamie:** That feels much more doable when you say it as one move.
-
-**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
-
----
-
-**Alex:** Now bring the learner back to the room. Anchor this part on The evidence. Your GitHub profile now contains real activity: issues filed, pull requests merged, code reviewed, and an agent contributed to an open source project.
-
-**Jamie:** What would you say to someone who is already bracing for this to be too much?
-
-**Alex:** The reason this matters is simple: the following table maps what you learned to where it applies beyond this workshop. The listener should be able to check this: Every skill transfers directly to real-world development.
-
-**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
-
-**Alex:** That matters because of the next idea. Skills you may not have noticed has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** On the ground, that means a few things. Reading documentation: You navigated technical guides, followed step-by-step instructions, and troubleshot problems using written references. This is the most important developer skill. Asking for help effectively: You posted on issues with context, error messages, and what you tried. This is how experienced developers communicate. Learning tools by doing: You did not read a manual cover to cover. You tried things, hit problems, and figured them out. This is how real tool learning works.
-
----
-
-**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
-
-**Alex:** If the interface shifts, 3. Building Your Developer Portfolio is still useful because see also: Appendix X: Resources has links to every tool and resource mentioned in this course. For someone navigating by keyboard or screen reader, this detail matters: Your GitHub profile is your portfolio.
-
-**Jamie:** What does the learner do first, second, and then after that?
-
-**Alex:** Pin your best repositories has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** The room should hear these as checkpoints. Your fork of the accessibility-agents repository (shows open source contribution). Any personal projects you create after the workshop.
-
-**Alex:** Walk it in order: Go to github.com/settings/profile; Scroll to "Pinned repositories."; and Pin the repositories that show your best work. Consider. Keep it that plain: know where you are, make the move, check the result.
-
-**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
-
-**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
-
-**Jamie:** What is the one idea that makes the next few steps less mysterious?
-
-**Alex:** The teaching point here is not the label; it is the move. Your profile README is the first thing people see when they visit your GitHub profile. That is the difference between guessing and knowing: Create a repository with the same name as your username (e.g., your-username/your-username) and add a README.md.
-
-**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
-
----
-
-**Alex:** Before the learner moves on. This part earns its place because the green squares on your GitHub profile show when you made contributions. That gives the learner a foothold: even small actions count: filing issues, opening PRs, making commits, and reviewing code. That is the difference between following directions and owning the workflow.
-
-**Jamie:** Give me the version that sounds like an instructor, not a manual.
-
-**Alex:** Learning Cards: Building Your Developer Portfolio has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** If someone is taking notes, this is the short list. Navigate to your profile settings at github.com/settings/profile -- the "Pinned repositories" section is a group of checkboxes; Tab through and press Space to pin or unpin. Your profile README repository must match your username exactly (case-sensitive) -- screen readers will read the rendered README as regular page content when visitors navigate your profile. The contribution graph is announced as a table or grid; arrow keys move between day cells, each announcing the date and contribution count. Pinned repositories appear as cards below your avatar -- at high zoom the 2x3 grid may reflow to a single column, which is easier to scan. The profile README renders with your current GitHub theme -- test yours in both light and dark modes to confirm text and images remain readable. Contribution graph squares use green intensity to show activity levels; enable high-contrast mode if the shading differences are hard to distinguish.
-
-**Alex:** Now slow down for the part people usually miss. Here is the learner-facing version. See also: Appendix Z: GitHub Skills has the complete catalog of recommended GitHub Skills courses. Put another way, the workshop taught you the fundamentals.
-
----
-
-**Jamie:** Where do you want a learner to place their attention here?
-
-**Alex:** Git and version control has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** These are the pieces that turn the idea into a usable move. Pro Git book -- Free, comprehensive, and the official Git resource. Start with chapters 2 and 3. Appendix E: Advanced Git -- Rebasing, cherry-picking, stashing, and other techniques you will need eventually.
-
-**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
-
-**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
-
-**Alex:** A solid Git habit is to know which branch you are on, what changed, and what confirmation you expect before you run the next command.
-
-**Alex:** Here is the moment where the page starts to make sense. GitHub platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Listen for the small confirmations in this list. GitHub Docs -- The official documentation covers everything. Bookmark it. GitHub Skills -- Free, interactive courses that teach by doing (see Section 5 below). GitHub Blog -- Stay current with new features and best practices.
-
-**Jamie:** What stays the same when the tool changes?
-
-**Alex:** VS Code has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** The useful version is not abstract; it sounds like this. VS Code documentation -- Complete reference for settings, keybindings, and extensions. VS Code accessibility documentation -- Deep dive into screen reader support, high contrast, and keyboard navigation.
-
----
-
-**Alex:** The next point gives the learner a handle. Accessibility has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** This is where the lesson becomes something you can check. Web Content Accessibility Guidelines (WCAG) 2.2 -- The quick reference version is the most practical. Appendix M: Accessibility Standards -- Workshop reference for WCAG criteria used in this course. WebAIM -- Practical accessibility resources, training, and tools. Deque University -- Free and paid courses on web accessibility.
-
-**Jamie:** Let's pause on AI-assisted development. What should a learner take away from it?
-
-**Alex:** AI-assisted development has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** A few details make that real. GitHub Copilot documentation -- Official docs for Copilot features, configuration, and best practices. Appendix K: Copilot Reference -- Workshop quick-reference card. Appendix L: Agents Reference -- Full accessibility agents roster and command reference.
-
-**Alex:** Hold that next to this. Put 5. GitHub Skills Courses to Try Next into plain language. GitHub Skills offers free, interactive courses that run inside GitHub repositories. The useful version is: Each course creates a repository in your account with step-by-step instructions and automated feedback -- the same model we used in this workshop. The interface gets easier when it becomes a set of named places instead of a wall of controls.
-
-**Jamie:** So the learner is not behind if they stop there and check the page.
-
-**Alex:** Yes. Pausing to verify is not a detour; it is how you keep control of the workflow.
-
----
-
-**Jamie:** Turn that into a path someone can follow.
-
-**Alex:** The teaching point here is not the label; it is the move. Each course takes 15 to 60 minutes.
-
-**Alex:** Think of this as 4 checks: Go to skills.github.com; Find a course and click its title; Click Start course (this creates a repository in your account); and Follow the instructions in the repository's README. Each step should leave a trace you can name.
-
-**Alex:** That connects to another useful point. Community Access has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** For a learner, the useful signals are concrete. Community Access on GitHub -- The organization behind this workshop. Watch the repositories for updates. For post-workshop questions, troubleshooting, and alumni conversation, use the open support hub: Community-Access/support.
-
-**Jamie:** Give me the sequence, because order matters here.
-
-**Alex:** Open source contribution: The capstone was your first contribution.
-
-**Alex:** First, start with projects you use. If you use a tool or library and find a bug or missing documentation, that is your first issue. Then, look for "good first issue" labels. Many projects label issues that are suitable for new contributors. After that, documentation counts. Fixing typos, improving instructions, and adding examples are valuable contributions. Do not underestimate them. Finally, the fork workflow scales. The same fork, branch, commit, push, PR workflow from Chapter 18 works for every GitHub project. That is the rhythm: orient, act, verify, continue.
-
----
-
-**Alex:** Here is the practical turn. Accessibility community has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** Here is what that changes in practice. GitHub Accessibility documentation -- Official accessibility guides for GitHub's interface. WebAIM mailing list -- Active discussion forum for web accessibility practitioners. A11y Project -- Community-driven accessibility resources and checklist.
-
-**Jamie:** How do the two days connect instead of feeling like separate courses?
-
-**Alex:** This is the move inside 7. Contributing Back to This Workshop: if you found something confusing, incorrect, or missing, you can fix it.
-
-**Jamie:** That is a useful checkpoint before anyone starts pressing keys.
-
-**Alex:** Exactly. Checkpoints turn uncertainty into information.
-
-**Jamie:** What is the ordered workflow?
-
-**Alex:** Anchor this part on The contribution workflow. You have already practiced every step of this workflow.
-
-**Alex:** Think of this as 4 checks: Fork the git-going-with-github repository; Clone your fork, create a branch, make your edit; Open a PR with a clear title and description; and Mention the chapter number and section in your PR. Keep it that plain: know where you are, make the move, check the result.
-
----
-
-**Jamie:** Where is the promise of the workshop, underneath all the logistics?
-
-**Alex:** Learning Cards: Contributing Back to This Workshop has three jobs: name the idea, give the learner a move, and show what counts as evidence.
-
-**Alex:** These are the details that keep the idea from floating away. The contribution workflow here is identical to Chapter 18 (Fork and Contribute) -- fork, clone, branch, edit, push, PR; use the same keyboard and screen reader patterns you already practiced. When filing an issue, include the chapter number and section heading in the title so maintainers can locate the problem with heading navigation. After opening a PR, listen for the automated check results in the PR timeline -- each check is announced as a link with its pass/fail status. The contribution types table above maps each kind of contribution to its workflow -- zoom in on the "How to do it" column for the quickest path. When editing documentation in your fork, use VS Code's Markdown Preview (Ctrl+Shift+V) at your preferred zoom level to verify formatting before pushing. PR descriptions render as Markdown on GitHub -- use headings and lists so reviewers can scan your changes at any zoom level.

-**Alex:** Another way to ground it. Do not treat 8. Final Words as decoration. Now you have filed issues, opened pull requests, resolved conflicts, reviewed code, and contributed to a real open source project. That is not trivia. Every expert started exactly where you are standing. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.

+#### Transcript
+
+**Alex:** Welcome to Git Going with GitHub: Agent Installation and Setup. I am Alex, and today we are teaching this topic as a conversation you can carry into the workshop, not as a page you have to memorize.
+
+**Jamie:** And I am Jamie. I will keep pulling the lesson back to real learners, real repositories, and the evidence that proves the work happened.
+
+---
+
+**Alex:** The lesson focus is Installing and configuring agent tooling across supported platforms, with practical setup checks and recovery steps. We will treat every step as a teachable decision, because that is what makes the skill portable.
+
+**Jamie:** So we should explain the why clearly enough that the steps make sense when the learner meets them later.
+
+**Alex:** That is it. If a listener only has audio right now, they should still get the complete concept and know what evidence would prove success.
+
+---
+
+**Jamie:** What do you want them to do when the plan breaks?
+
+**Alex:** Installation, Configuration, and Troubleshooting for All Five Platforms: This appendix covers the step-by-step installation process for Accessibility Agents on GitHub Copilot (VS Code), Claude Code, Gemini CLI, Claude Desktop, and Codex CLI, plus system requirements, version checking, and troubleshooting for each platform.
+
+**Alex:** The next layer is this. Here is the learner-facing version. Accessibility Agents requires the latest versions of all tools. Put another way, older versions miss accessibility features, API capabilities, and bug fixes that agents depend on. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Alex:** Here are the anchors worth keeping. VS Code: 1.113 or later (stable or Insiders). GitHub Copilot: Latest from VS Code Marketplace. Node.js: v18.0.0 or higher. Python: 3.8+.
+
+**Jamie:** What is the safe way to learn from that example?
+
+**Alex:** GitHub Copilot (VS Code) has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like VS Code 1.113+; - GitHub Copilot extension (latest); - GitHub Copilot Chat extension (latest); Node.js 18.0.0+ (for Playwright, axe-core, other tools); Git 2.20+ (for repository operations). Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** That feels much more doable when you say it as one move.
+
+**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+
+---
+
+**Jamie:** What should happen before anyone copies and runs it?
+
+**Alex:** Codex CLI has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Codex CLI (latest); - Installation: npm install -g @codex-cli/core; Node.js 18.0.0+ required for npm. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** What should someone listen for when a lesson offers more than one tool path?
+
+**Alex:** The reason this matters is simple: use these commands to verify your installed versions before starting.
+
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+
+**Jamie:** How do you keep commands from becoming magic words?
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Check VS Code version; code --version; Verify GitHub Copilot extension is installed; code --list-extensions grep -i copilot; Check Node.js (used by Copilot and accessibility tools); node --version; npm --version; Verify Git; git --version. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+---
+
+**Jamie:** What should they understand before typing anything?
+
+**Alex:** Claude Code has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Check Claude Code CLI version; claude code --version; Verify you have an active subscription; claude code whoami; Check Node.js; node --version. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Gemini CLI. What should a learner take away from it?
+
+**Alex:** Gemini CLI has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Check Gemini CLI version; gemini --version; Verify API key is configured; gemini config show; Check Node.js; node --version. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+
+**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+
+**Jamie:** What stays the same when the tool changes?
+
+**Alex:** The teaching point here is not the label; it is the move. Check inside the application: Settings → About to see the current version.
+
+---
+
+**Jamie:** Let's pause on Codex CLI. What should a learner take away from it?
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Check Codex CLI version; codex --version; Check Node.js; node --version; npm --version. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Give me the sequence, because order matters here.
+
+**Alex:** GitHub Copilot (VS Code) - Recommended for Most Workshops: Step 2: Install GitHub Copilot Extensions. The next useful detail is concrete: Step 3: Install Node.js (for accessibility tools).
+
+**Alex:** If someone is taking notes, this is the short list. GitHub Copilot (by GitHub). GitHub Copilot Chat (by GitHub).
+
+**Alex:** First, download from code.visualstudio.com. Then, run installer. After that, open VS Code and verify it starts. Finally, open Extensions panel: Ctrl+Shift+X (or View → Extensions ). Each step should leave a trace you can name.
+
+**Jamie:** How would you walk the room through that step by step?
+
+**Alex:** Start here: Search for "GitHub Copilot". Then: Install both. Next: Sign in with your GitHub account when prompted. Last: Download from nodejs.org (v18 LTS or later). If one step does not match what you hear, stop there and re-orient.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like cd /path/to/projects; git clone https://github.com/Community-Access/accessibility-agents.git; cd accessibility-agents. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Claude Code. What should a learner take away from it?
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @anthropic-ai/claude-code. cd /path/to/projects; git clone https://github.com/Community-Access/accessibility-agents.git; cd accessibility-agents. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+---
+
+**Jamie:** What does the learner do first, second, and then after that?
+
+**Alex:** This is the move inside Gemini CLI: step 4: Use with Accessibility Agents.
+
+**Alex:** Walk it in order: Get API key from ai.google.dev; and Set environment variable. That is the rhythm: orient, act, verify, continue.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @google/gemini-cli. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
+
+**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
+
+**Jamie:** Turn that into a path someone can follow.
+
+**Alex:** Claude Desktop has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Think of this as 4 checks: Download from claude.ai; Install application; Open Claude Desktop; and Create or edit.mcp.json in your home folder (macOS/Linux: /.mcp.json, Windows: %USERPROFILE%\.mcp.json). That small check between steps is what makes the workflow reliable.
+
+**Jamie:** What is the ordered workflow?
+
+**Alex:** The path is straightforward once it is named. Step one is add the Accessibility Agents MCP server. Step two is quit Claude Desktop completely. Step three is reopen Claude Desktop. Step four is verify MCP server connects (check logs). The sequence works because every action has a confirmation.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like {; "mcpServers": {; "accessibility-agents": {; "command": "node",; "args": ["/path/to/accessibility-agents/mcp-server/index.js"],; "env": {; "PORT": "3000"; }; }; }; }. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Before we leave Codex CLI, what is the practical point?
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like npm install -g @codex-cli/core. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+---
+
+**Alex:** The next point gives the learner a handle. Do not treat Verification Checklist as decoration. After installation, verify each platform is ready.
+
+**Jamie:** Let's pause on Quick Test: Run One Agent. What should a learner take away from it?
+
+**Alex:** If the interface shifts, Quick Test: Run One Agent is still useful because on Claude Desktop: In chat input, type: @daily-briefing morning briefing. For someone navigating by keyboard or screen reader, this detail matters: If the agent responds with information, installation is successful.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Open Chat (Ctrl+Alt+I) → Type: @daily-briefing morning briefing. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Universal Troubleshooting. What should a learner take away from it?
+
+**Alex:** Universal Troubleshooting has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** That shows up in the workshop in a few specific ways. Ensure ports 443 (HTTPS), 3000 (MCP) are not blocked. If behind proxy, configure Git: git config --global http.proxy [proxy-url]. VS Code: Reload Window (Ctrl+Shift+P → "Reload Window"). CLI tools: Reinstall latest version. GitHub Copilot: Requires active subscription (Free, Pro, or Team). Claude Code: Requires Claude Pro/Team/Enterprise.
+
+**Alex:** Walk it in order: Verify internet connection; Check firewall/proxy; Clear caches and restart; and Check subscription/quota. The point is not speed; the point is never losing your place.
+
+**Jamie:** Before we leave Universal Troubleshooting, what is the practical point?
+
+**Alex:** Think of this as 1 checks: Review logs. Each step should leave a trace you can name.
+
+**Jamie:** So the learner is not behind if they stop there and check the page.
+
+**Alex:** Yes. Pausing to verify is not a detour; it is how you keep control of the workflow.
+
+---
+
+**Jamie:** Okay, set the room for us. What are we walking into?
+
+**Alex:** Why Updates Matter has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** For a learner, the useful signals are concrete. New accessibility features in platforms enable better agent behavior. Bug fixes prevent silent failures and context loss. API improvements improve performance and reliability. Security patches protect your data and credentials.
+
+**Jamie:** Let's pause on Update Commands. What should a learner take away from it?
+
+**Alex:** This part earns its place because verify current versions after update.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Update VS Code; code --update; Update extensions; Use VS Code UI: Extensions → click update on GitHub Copilot extensions. npm update -g. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Update Best Practices. What should a learner take away from it?
+
+**Alex:** Update Best Practices has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** First, update before starting a new project: Ensure latest fixes and features are available. Then, keep Node.js current: Many CLI tools depend on Node.js features. After that, check compatibility notes: Major version updates may introduce breaking changes. Finally, test in a branch: After updating, test one agent before relying on it. That is the rhythm: orient, act, verify, continue.
+
+**Jamie:** Before we leave Update Best Practices, what is the practical point?
+
+**Alex:** Start here: Subscribe to release notes: Watch Accessibility Agents releases for new features and requirements. That small check between steps is what makes the workflow reliable.
+
+**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+
+---
+
+**Alex:** Here is the practical turn. Learning Cards: Installation & Setup has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** On the ground, that means a few things. Installation steps are presented in sequence; follow them in order and do not skip any step. After installation, the quick verification test (running @daily-briefing) confirms setup is working -- if it produces a response, you are ready to proceed. Each platform has its own section; use headings (H key in browse mode) to jump to the section for your chosen platform. Troubleshooting tables are organized by platform; navigate to your platform's row for solutions. The system requirements table can be magnified independently; zoom in on the "Minimum Version" and "Notes" columns if you need specific details. Installation commands are in code blocks with clear context; copy the command that matches your platform.
+
+**Jamie:** What would you say to someone who is already bracing for this to be too much?
+
+**Alex:** References has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is what that changes in practice. Accessibility Agents Repository. VS Code Installation Guide. GitHub Copilot Documentation. Claude Code Documentation. Gemini CLI GitHub. Node.js Installation.
+
+**Jamie:** That is a useful checkpoint before anyone starts pressing keys.
+
+**Alex:** Exactly. Checkpoints turn uncertainty into information.
+
+---
+
+**Jamie:** What should people carry with them after this?
+
+**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+
+**Jamie:** That is a better way to say it than just follow the steps.
+
+**Alex:** Right. Steps matter, but understanding wins. Keep the next learning block nearby, because each part of the series keeps building the same contributor muscles.

+
+#### Transcript
+
+**Alex:** Welcome to Git Going with GitHub: Advanced Agent Patterns. I am Alex. Today we are going to make Advanced Agent Patterns something you can explain, practice, and recover from when the interface surprises you.
+
+**Jamie:** And I am Jamie. I will be the voice of the learner who is willing to ask, what is this for, where am I, and how do I know I did it right?
+
+---
+
+**Alex:** The big idea today: Advanced patterns for multi-agent workflows, orchestration, guardrails, and evaluation in real projects. We will name the concept, explain why it matters, practice the move, and point out the checks that tell you the work is real.
+
+**Jamie:** So the episode should work even if someone has not read the chapter yet.
+
+**Alex:** Exactly. The transcript has to stand on its own. It can point toward practice, but it should teach the concept right here in the conversation.
+
+---
+
+**Jamie:** Okay, set the room for us. What are we walking into?
+
+**Alex:** Architecture, Skills, Hooks, and Advanced Patterns for AI Agents: This appendix covers how to build sophisticated agent workflows using subagent delegation, lifecycle hooks, reusable skills, and browser automation tools. The next useful detail is concrete: These patterns scale beyond single-agent use to orchestrate complex accessibility audits and remediation workflows.
+
+**Alex:** The next layer is this. Here is the learner-facing version. An agent is a standalone AI system (like @aria-specialist) that understands one domain (ARIA patterns). Put another way, a subagent is an agent invoked by another agent to delegate work. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
+
+**Alex:** This is the move inside How to Use Subagents: in your agent's instructions or a custom prompt, invoke subagents with the runSubagent() function. That matters in practice: // Pseudo-code - how agents invoke subagents const results = await runSubagent({ agentName: '@aria-specialist', prompt: 'Check this component for ARIA compliance: ', description: 'ARIA pattern review' });.
+
+**Jamie:** That feels much more doable when you say it as one move.
+
+**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+
+---
+
+**Alex:** Now bring the learner back to the room. Anchor this part on Invoke Skills. When you need to audit a webpage, use the web-scanning skill. This is the part to say slowly: "Scan the following URL for accessibility issues and generate a severity score.".
+
+**Alex:** For a learner, the useful signals are concrete. URL: https://example.com. Severity model: WCAG 2.2 AA. Output: JSON report.
+
+**Jamie:** What would you say to someone who is already bracing for this to be too much?
+
+**Alex:** The reason this matters is simple: what problem does this skill solve?
+
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+
+**Alex:** That matters because of the next idea. Inputs has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** On the ground, that means a few things. URL or file path. Configuration (optional).
+
+---
+
+**Jamie:** How would you walk the room through that step by step?
+
+**Alex:** Workflow has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Start here: Parse input. Then: Execute steps. Next: Collect results. Last: Format output. The sequence works because every action has a confirmation.
+
+**Alex:** This is where the talk moves from concept to action. Output has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The room should hear these as checkpoints. Report format (JSON, Markdown, CSV). Example output.
+
+**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+
+**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+
+**Jamie:** Where do you want a learner to place their attention here?
+
+**Alex:** The teaching point here is not the label; it is the move. { "name": "aria-proactive-check", "event": "on-file-edit", "pattern": "src/ /.jsx", "agent": "@aria-specialist", "condition": "true", "action": "highlight-violations", "severity": "warning" }. That is the difference between guessing and knowing: { "name": "accessibility-commit-gate", "event": "on-commit", "pattern": " / ", "agent": "@web-accessibility-wizard", "condition": "severity = 'error'", "action": "block-save", "message": "Critical accessibility issues detected.
+
+**Alex:** These are the details that keep the idea from floating away. Links to related agents. Links to external docs.
+
+---
+
+**Jamie:** What is the ordered workflow?
+
+**Alex:** This part earns its place because when the user provides a URL, use the scan-page tool. That gives the learner a foothold: example: User: Audit https://example.com for accessibility issues Agent. That is the difference between following directions and owning the workflow.
+
+**Alex:** That becomes easier when you listen for these cues. Calls scan-page("https://example.com"). Receives findings JSON. Groups by category and severity. Reports top 10 issues.
+
+**Alex:** The path is straightforward once it is named. Step one is call scan-page(url) to get accessibility findings. Step two is filter findings by severity. Step three is group by category (ARIA, contrast, keyboard, etc.). Step four is present results in a prioritized table. The point is not speed; the point is never losing your place.
+
+**Jamie:** Give me the sequence, because order matters here.
+
+**Alex:** Smart Audit Based on Page Content: // Pseudo-code: Test a multi-step form const browser = await playwright.launch(); const page = await browser.newPage();. The next useful detail is concrete: await page.goto('https://example.com/form'); await page.fill(' name', 'Jane Doe'); await page.fill(' email', 'jane@example.com'); await page.click('button:has-text("Submit")');.
+
+**Alex:** If someone is taking notes, this is the short list. Recommend structure fixes (use @alt-text-headings). Recommend ARIA review (use @aria-specialist). Recommend behavioral testing (use @testing-coach). Severity: 12 errors, 8 warnings.
+
+**Alex:** First, call get-page-outline(url) to understand structure. Then, if heading hierarchy is broken. After that, if many interactive components detected. Finally, if dynamic content detected. Each step should leave a trace you can name.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like Browser Tool Limitations and Workarounds; Limitation Workaround; ------------ -----------; Cannot test with actual screen readers Use @testing-coach guidance instead; CLI offers NVDA integration; JavaScript-heavy pages may be incomplete Increase wait time. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** What does the learner do first, second, and then after that?
+
+**Alex:** Here is the learner-facing version. Invoke all specialist agents in parallel. Put another way, output: Numbered PR suggestions, 1 fix per commit message.
+
+**Alex:** Here is the part that makes the next action easier. Have you used NVDA before? What platform (Windows/Mac/Linux)? What component type (form/menu/modal)? Step 1: Learn Tab order basics (video link).
+
+**Alex:** Start here: Gather all findings simultaneously (not sequentially). Then: Deduplicate issues across agents. Next: Sort by severity. Last: Present top 10 blocking issues first. If one step does not match what you hear, stop there and re-orient.
+
+**Jamie:** Turn that into a path someone can follow.
+
+**Alex:** Walk it in order: Link to detailed fix guidance per agent; Missing alt text (3 images); Poor color contrast (5 elements); and Missing form labels (2 inputs). That is the rhythm: orient, act, verify, continue.
+
+---
+
+**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
+
+**Alex:** This is the move inside Purpose: codify internal accessibility standards and patterns used across all projects.
+
+**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
+
+**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
+
+**Jamie:** Let's pause on Patterns Included. What should a learner take away from it?
+
+**Alex:** Patterns Included has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Think of this as 4 checks: Form validation messaging; Accessible modal templates; Color palette compliance; and Data table best practices. That small check between steps is what makes the workflow reliable.
+
+**Jamie:** Give me the version that sounds like an instructor, not a manual.
+
+**Alex:** Inputs has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The useful version is not abstract; it sounds like this. HTML snippet or component name. Pattern ID (e.g., "form-validation-v2").
+
+---
+
+**Alex:** The next point gives the learner a handle. Output has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** This is where the lesson becomes something you can check. Remediation code. Compliance checklist. Testing steps.
+
+**Jamie:** Let's pause on Usage. What should a learner take away from it?
+
+**Alex:** If the interface shifts, Usage is still useful because @custom-agent check-pattern "form-validation-v2" [HTML]. For someone navigating by keyboard or screen reader, this detail matters: { "name": "continuous-accessibility-eval", "event": "on-schedule", "schedule": "0 0 0", "pattern": "src/ / ", "agent": "@accessibility-lead", "action": "create-eval-report", "track": { "metrics": ["page-score", "error-count", "warning-count"], "baseline".
+
+---
+
+**Jamie:** What should people carry with them after this?
+
+**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+
+**Jamie:** That is a better way to say it than just follow the steps.
+
+**Alex:** Right. Steps matter, but understanding wins. Keep the next learning block nearby, because each part of the series keeps building the same contributor muscles.

+
+#### Transcript
+
+**Alex:** Welcome back to Git Going with GitHub. This is Document and Developer Tool Agents. I am Alex, and today we are turning Document and Developer Tool Agents from a list of instructions into a working mental model.
+
+**Jamie:** And I am Jamie. I will stop us whenever the instructions sound simple on paper but might feel different with a keyboard and screen reader.
+
+---
+
+**Alex:** Using specialized agents for document workflows and developer tooling with accessibility-focused guardrails. That is the surface description. Underneath it, we are building judgment: where to focus, what to ignore, and how to verify the result.
+
+**Jamie:** So we are not using the audio as a shortcut around learning. We are using it to make the learning easier to enter.
+
+**Alex:** Yes. A good audio lesson gives someone enough context to try the work with confidence, even before they open the written material.
+
+---
+
+**Jamie:** There are a lot of tools in play. How do we keep that from feeling like a contest?
+
+**Alex:** Specialized Agents for Office Documents, PDFs, and Developer Tools: This appendix covers the 15 agents dedicated to document accessibility (Word, Excel, PowerPoint, PDF, EPUB) and developer tools (Python, wxPython, NVDA, CI/CD). The next useful detail is concrete: Learn how to audit and remediate documents, build accessible applications, and integrate accessibility into development workflows.
+
+**Alex:** The next layer is this. Here is the learner-facing version. The Document Accessibility Team provides specialized agents for scanning, remediating, and enforcing accessibility standards in business documents. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.
+
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
+
+**Alex:** This is the move inside PDF Accessibility (PDF/UA Standard): pDF/UA (Universal Accessibility) is the ISO standard for accessible PDFs.
+
+**Jamie:** That feels much more doable when you say it as one move.
+
+**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+
+---
+
+**Alex:** Now bring the learner back to the room. Anchor this part on EPUB Accessibility. EPUB files are digital publications (e-books, online articles). This is the part to say slowly: Accessibility requirements overlap with HTML.
+
+**Alex:** For a learner, the useful signals are concrete. Table of contents matches document structure. Heading hierarchy follows H1, H2, H3. order. Images have alt text. Links have meaningful text.
+
+**Jamie:** What should someone listen for when a lesson offers more than one tool path?
+
+**Alex:** The reason this matters is simple: the Developer Tools Team supports accessible application development across Python, wxPython, CI/CD pipelines, and desktop environments.
+
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+
+**Alex:** That matters because of the next idea. Do not treat Python Accessibility Best Practices as decoration. Common patterns in accessible Python code. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+
+**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+
+---
+
+**Jamie:** What is the safe way to learn from that example?
+
+**Alex:** If the interface shifts, wxPython GUI Accessibility is still useful because wxPython is a cross-platform GUI toolkit. For someone navigating by keyboard or screen reader, this detail matters: Accessibility requires following platform conventions.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like User: @wxpython-specialist audit my-app.py; Agent response:; 1. Analyzes wxPython code:; - Control labeling; - Tab order; - Keyboard support; - Dialog structure; 2. Reports:; - 2 controls missing labels; - Tab order needs sorting (currently 5, 3, 1, 2, 4); -. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** What should happen before anyone copies and runs it?
+
+**Alex:** Put Desktop Application Accessibility into plain language. Desktop applications must follow OS conventions.
+
+**Alex:** The room should hear these as checkpoints. All controls must expose their role (button, text, etc.). Labels and descriptions required. Keyboard navigation essential. Focus must be visible. Controls expose accessibility attributes. VoiceOver announces all changes.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like User: @desktop-a11y-specialist test my-app --platform windows; Agent response:; 1. Checks Windows accessibility:; - UIA object properties; - Keyboard navigation; - Focus indicators; - Screen reader compatibility (NVDA); 2. Runs NVDA simulation:; - Lists all. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+
+**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+
+**Jamie:** What should they understand before typing anything?
+
+**Alex:** The teaching point here is not the label; it is the move. NVDA (free, open-source screen reader) supports add-ons for extended functionality.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like User: @nvda-addon-developer create an add-on that improves announcement of custom web components; Agent response:; 1. Scaffolds project structure; 2. Creates sample globalPlugin; 3. Provides template for:; - Event handling (focus, name change); - Custom. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+---
+
+**Jamie:** How do you keep commands from becoming magic words?
+
+**Alex:** This part earns its place because add accessibility checks to your CI/CD pipeline. That gives the learner a foothold: example: Lighthouse Accessibility Check. That is the difference between following directions and owning the workflow.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like.github/workflows/accessibility.yml; name: Accessibility Check; on: [push, pull request]; jobs:; accessibility:; runs-on: ubuntu-latest; steps:; - uses: actions/checkout@v3; - uses: actions/setup-node@v3; with:; node-version: '18'; - run: npm install; - run. Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Jamie:** Let's pause on Playwright Accessibility Testing. What should a learner take away from it?
+
+**Alex:** Playwright Accessibility Testing has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Treat examples as spoken recipes, not decorations. You may hear something like // tests/keyboard.spec.ts; import { test, expect } from '@playwright/test';; test('form accessible by keyboard only', async ({ page }) = {; await page.goto('https://example.com/form');; // Tab through form without mouse; await page.keyboard.press('Tab'). Read the command, understand what it changes, then run it only when the repository state matches the lesson.
+
+**Alex:** Now slow down for the part people usually miss. Learning Cards: Document & Developer Tools has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is the part that makes the next action easier. Document agents are organized by file type (Word, Excel, PDF, EPUB); use headings to jump to your document type. Each agent has a clear purpose in the table at the beginning; read the "Purpose" column to find the agent you need. Code examples (Python, wxPython) are presented in clearly marked code blocks; copy the example that matches your use case. Troubleshooting steps for each document type are presented in numbered lists; follow them in order. The agent overview table can be magnified independently; zoom in on the "Agent", "Purpose", and "When to Use" columns. Code examples use consistent indentation; magnify the entire code block for clarity.
+
+---
+
+**Jamie:** Okay, set the room for us. What are we walking into?
+
+**Alex:** References has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** These are the pieces that turn the idea into a usable move. Document Accessibility Best Practices. PDF/UA Standard. EPUB Accessibility. wxPython Documentation. NVDA Add-on Developer Guide. Playwright Accessibility Testing.
+
+**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
+
+**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
+
+---
+
+**Jamie:** What should people carry with them after this?
+
+**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+
+**Jamie:** That is a better way to say it than just follow the steps.

+
+#### Transcript
+
+**Alex:** This is Git Going with GitHub: What Comes Next. I am Alex. By the end of this lesson, What Comes Next should feel less like a wall of GitHub words and more like a set of moves you can trust.
+
+**Jamie:** And I am Jamie. I am here for the practical questions: what should I listen for, what can go wrong, and what is the next calm move?
+
+---
+
+**Alex:** Today we are working on this: The closing lesson in the listening path: what you accomplished, where to go next, and how to keep contributing after the workshop. I want the learner to leave with a mental map, not just a remembered path through buttons.
+
+**Jamie:** So the goal is understanding first, then action, then confirmation.
+
+**Alex:** Right. We are building a rhythm: orient yourself, take one intentional action, then verify what changed before moving on.
+
+---
+
+**Jamie:** Okay, set the room for us. What are we walking into?
+
+**Alex:** 1. What You Built in Two Days: Take a moment to appreciate what you accomplished. The next useful detail is concrete: This is not a list of what you were taught -- it is a list of what you did.
+
+**Alex:** The next layer is this. Day 1: You Can Navigate This has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here are the anchors worth keeping. Created and configured a GitHub account with accessibility settings. Navigated repositories, files, and folders using your screen reader, keyboard, or preferred tools. Filed issues with descriptive titles, labels, and context. Created branches, edited files, and opened pull requests. Responded to bot feedback and passed automated checks. Resolved a merge conflict.
+
+**Jamie:** What should feel predictable before the first live session starts?
+
+**Alex:** Day 2: You Can Build This has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** That shows up in the workshop in a few specific ways. Installed and configured VS Code with accessibility settings. Cloned a repository and worked with Git locally. Understood the mental model: working directory, staging area, repository. Created branches, staged changes, committed, and pushed from the command line. Explored GitHub Copilot: code suggestions, chat, and code review. Created an issue template.
+
+**Jamie:** That feels much more doable when you say it as one move.
+
+**Alex:** Right. The magic is not speed. The magic is knowing what changed and why it matters.
+
+---
+
+**Alex:** Now bring the learner back to the room. Anchor this part on The evidence. Your GitHub profile now contains real activity: issues filed, pull requests merged, code reviewed, and capstone evidence prepared for a real repository.
+
+**Jamie:** What would you say to someone who is already bracing for this to be too much?
+
+**Alex:** The reason this matters is simple: the following table maps what you learned to where it applies beyond this workshop. The listener should be able to check this: Every skill transfers directly to real-world development.
+
+**Alex:** The useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.
+
+**Alex:** That matters because of the next idea. Skills you may not have noticed has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** On the ground, that means a few things. Reading documentation: You navigated technical guides, followed step-by-step instructions, and troubleshot problems using written references. This is the most important developer skill. Asking for help effectively: You posted on issues with context, error messages, and what you tried. This is how experienced developers communicate. Learning tools by doing: You did not read a manual cover to cover. You tried things, hit problems, and figured them out. This is how real tool learning works.
+
+---
+
+**Jamie:** If I am listening before the workshop starts, what should settle in my mind first?
+
+**Alex:** If the interface shifts, 3. Building Your Developer Portfolio is still useful because see also: Appendix X: Resources has links to every tool and resource mentioned in this course. For someone navigating by keyboard or screen reader, this detail matters: Your GitHub profile is your portfolio.
+
+**Jamie:** What does the learner do first, second, and then after that?
+
+**Alex:** Pin your best repositories has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The room should hear these as checkpoints. Your fork of the accessibility-agents repository (shows open source contribution). Any personal projects you create after the workshop.
+
+**Alex:** Walk it in order: Go to github.com/settings/profile; Scroll to "Pinned repositories."; and Pin the repositories that show your best work. Consider. Keep it that plain: know where you are, make the move, check the result.
+
+**Jamie:** Now it sounds like a workflow instead of a wall of instructions.
+
+**Alex:** That is where confidence comes from: not from never getting lost, but from knowing how to recover.
+
+**Jamie:** What is the one idea that makes the next few steps less mysterious?
+
+**Alex:** The teaching point here is not the label; it is the move. Your profile README is the first thing people see when they visit your GitHub profile. That is the difference between guessing and knowing: Create a repository with the same name as your username (e.g., your-username/your-username) and add a README.md.
+
+**Alex:** A solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.
+
+---
+
+**Alex:** Before the learner moves on. This part earns its place because the green squares on your GitHub profile show when you made contributions. That gives the learner a foothold: even small actions count: filing issues, opening PRs, making commits, and reviewing code. That is the difference between following directions and owning the workflow.
+
+**Jamie:** Give me the version that sounds like an instructor, not a manual.
+
+**Alex:** Learning Cards: Building Your Developer Portfolio has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** If someone is taking notes, this is the short list. Navigate to your profile settings at github.com/settings/profile -- the "Pinned repositories" section is a group of checkboxes; Tab through and press Space to pin or unpin. Your profile README repository must match your username exactly (case-sensitive) -- screen readers will read the rendered README as regular page content when visitors navigate your profile. The contribution graph is announced as a table or grid; arrow keys move between day cells, each announcing the date and contribution count. Pinned repositories appear as cards below your avatar -- at high zoom the 2x3 grid may reflow to a single column, which is easier to scan. The profile README renders with your current GitHub theme -- test yours in both light and dark modes to confirm text and images remain readable. Contribution graph squares use green intensity to show activity levels; enable high-contrast mode if the shading differences are hard to distinguish.
+
+**Alex:** Now slow down for the part people usually miss. Here is the learner-facing version. See also: Appendix Z: GitHub Skills has the complete catalog of recommended GitHub Skills courses. Put another way, the workshop taught you the fundamentals.
+
+---
+
+**Jamie:** Where do you want a learner to place their attention here?
+
+**Alex:** Git and version control has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** These are the pieces that turn the idea into a usable move. Pro Git book -- Free, comprehensive, and the official Git resource. Start with chapters 2 and 3. Appendix E: Advanced Git -- Rebasing, cherry-picking, stashing, and other techniques you will need eventually.
+
+**Jamie:** That is the kind of detail that keeps a screen reader user oriented.
+
+**Alex:** Yes. The named thing - the heading, tab, field, branch, or button - is the handhold.
+
+**Alex:** A solid Git habit is to know which branch you are on, what changed, and what confirmation you expect before you run the next command.
+
+**Alex:** Here is the moment where the page starts to make sense. GitHub platform has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Listen for the small confirmations in this list. GitHub Docs -- The official documentation covers everything. Bookmark it. GitHub Skills -- Free, interactive courses that teach by doing (see Section 5 below). GitHub Blog -- Stay current with new features and best practices.
+
+**Jamie:** What stays the same when the tool changes?
+
+**Alex:** VS Code has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** The useful version is not abstract; it sounds like this. VS Code documentation -- Complete reference for settings, keybindings, and extensions. VS Code accessibility documentation -- Deep dive into screen reader support, high contrast, and keyboard navigation.
+
+---
+
+**Alex:** The next point gives the learner a handle. Accessibility has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** This is where the lesson becomes something you can check. Web Content Accessibility Guidelines (WCAG) 2.2 -- The quick reference version is the most practical. Appendix M: Accessibility Standards -- Workshop reference for WCAG criteria used in this course. WebAIM -- Practical accessibility resources, training, and tools. Deque University -- Free and paid courses on web accessibility.
+
+**Jamie:** Let's pause on AI-assisted development. What should a learner take away from it?
+
+**Alex:** AI-assisted development has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** A few details make that real. GitHub Copilot documentation -- Official docs for Copilot features, configuration, and best practices. Appendix K: Copilot Reference -- Workshop quick-reference card. Appendix L: Agents Reference -- Full accessibility agents roster and command reference.
+
+**Alex:** Hold that next to this. Put 5. GitHub Skills Courses to Try Next into plain language. GitHub Skills offers free, interactive courses that run inside GitHub repositories. The useful version is: Each course creates a repository in your account with step-by-step instructions and automated feedback -- the same model we used in this workshop. The interface gets easier when it becomes a set of named places instead of a wall of controls.
+
+**Jamie:** So the learner is not behind if they stop there and check the page.
+
+**Alex:** Yes. Pausing to verify is not a detour; it is how you keep control of the workflow.
+
+---
+
+**Jamie:** Turn that into a path someone can follow.
+
+**Alex:** The teaching point here is not the label; it is the move. Each course takes 15 to 60 minutes.
+
+**Alex:** Think of this as 4 checks: Go to skills.github.com; Find a course and click its title; Click Start course (this creates a repository in your account); and Follow the instructions in the repository's README. Each step should leave a trace you can name.
+
+**Alex:** That connects to another useful point. Community Access has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** For a learner, the useful signals are concrete. Community Access on GitHub -- The organization behind this workshop. Watch the repositories for updates. For post-workshop questions, troubleshooting, and alumni conversation, use the open support hub: Community-Access/support.
+
+**Jamie:** Give me the sequence, because order matters here.
+
+**Alex:** Open source contribution: The capstone was your first contribution.
+
+**Alex:** First, start with projects you use. If you use a tool or library and find a bug or missing documentation, that is your first issue. Then, look for "good first issue" labels. Many projects label issues that are suitable for new contributors. After that, documentation counts. Fixing typos, improving instructions, and adding examples are valuable contributions. Do not underestimate them. Finally, the fork workflow scales. The same fork, branch, commit, push, PR workflow from Chapter 18 works for every GitHub project. That is the rhythm: orient, act, verify, continue.
+
+---
+
+**Alex:** Here is the practical turn. Accessibility community has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** Here is what that changes in practice. GitHub Accessibility documentation -- Official accessibility guides for GitHub's interface. WebAIM mailing list -- Active discussion forum for web accessibility practitioners. A11y Project -- Community-driven accessibility resources and checklist.
+
+**Jamie:** How do the two days connect instead of feeling like separate courses?
+
+**Alex:** This is the move inside 7. Contributing Back to This Workshop: if you found something confusing, incorrect, or missing, you can fix it.
+
+**Jamie:** That is a useful checkpoint before anyone starts pressing keys.
+
+**Alex:** Exactly. Checkpoints turn uncertainty into information.
+
+**Jamie:** What is the ordered workflow?
+
+**Alex:** Anchor this part on The contribution workflow. You have already practiced every step of this workflow.
+
+**Alex:** Think of this as 4 checks: Fork the git-going-with-github repository; Clone your fork, create a branch, make your edit; Open a PR with a clear title and description; and Mention the chapter number and section in your PR. Keep it that plain: know where you are, make the move, check the result.
+
+---
+
+**Jamie:** Where is the promise of the workshop, underneath all the logistics?
+
+**Alex:** Learning Cards: Contributing Back to This Workshop has three jobs: name the idea, give the learner a move, and show what counts as evidence.
+
+**Alex:** These are the details that keep the idea from floating away. The contribution workflow here is identical to Chapter 18 (Fork and Contribute) -- fork, clone, branch, edit, push, PR; use the same keyboard and screen reader patterns you already practiced. When filing an issue, include the chapter number and section heading in the title so maintainers can locate the problem with heading navigation. After opening a PR, listen for the automated check results in the PR timeline -- each check is announced as a link with its pass/fail status. The contribution types table above maps each kind of contribution to its workflow -- zoom in on the "How to do it" column for the quickest path. When editing documentation in your fork, use VS Code's Markdown Preview (Ctrl+Shift+V) at your preferred zoom level to verify formatting before pushing. PR descriptions render as Markdown on GitHub -- use headings and lists so reviewers can scan your changes at any zoom level.
+
+**Alex:** Another way to ground it. Do not treat If You Get Stuck After the Workshop as decoration. Before you open a new browser tab and search the whole internet, use the workshop support path you already practiced. That is not trivia. Start with the Course Guide when you need the map, the Challenge Hub when you need the challenge-by-challenge checklist, and Get Going with GitHub when you need the onboarding path again. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.
+
+**Jamie:** Let's pause on 8. Final Words. What should a learner take away from it?
+
+**Alex:** If the interface shifts, 8. Final Words is still useful because now you have filed issues, opened pull requests, resolved conflicts, reviewed code, and contributed to a real open source project. For someone navigating by keyboard or screen reader, this detail matters: Every expert started exactly where you are standing.
+
+---
+
+**Jamie:** What should people carry with them after this?
+
+**Alex:** Carry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.
+
+**Jamie:** That is a better way to say it than just follow the steps.
+
+**Alex:** Right. Steps matter, but understanding wins. Keep the next learning block nearby, because each part of the series keeps building the same contributor muscles.

 The Classroom test-case definitions that used to live in `classroom/autograding-day1.json` and `classroom/autograding-day2.json` were deleted in May 2026 along with this workflow migration. The autograder workflow files (`learning-room/.github/workflows/autograder-*.yml`) are the only remaining source of truth for what each check verifies. Git history retains the old JSONs if you ever need to read them.

+# Challenge Content Review
+
+This document contains the complete set of instructions for all 9 challenges. 
+It has been written to prioritize accessibility, inclusive language, and clear progression. Visual dependencies (like "green button"), sensory verbs (like "see" or "look at"), and mouse-specific actions (like "click") have been replaced with inclusive terminology ("activate", "select", "navigate", "verify").
+
+You can review, edit, and refine the content here. Once finalized, Challenge 1 should be pre-created in the template repository, and Challenges 2-9 will be updated in the `student-progression.yml` bot.
+
+---
+
+## Challenge 1: Find Your Way Around (Initial State)
+
+*(Note: This issue will be pre-created in the `learning-room-template` repository so it is waiting for the student when they arrive).*
+
+**Title:** Challenge 1: Find Your Way Around
+
+**Body:**
+**Welcome to Git Going with GitHub!**
+
+We are thrilled to have you here. This repository is your safe, private learning environment for Day 1. Let's start by getting comfortable with your surroundings. 
+
+**Your Goal:**
+Explore the main areas of a GitHub repository and locate where the files live.
+
+**Step-by-Step:**
+
+<details>
+<summary><b>Web Browser</b></summary>
+
+1. Navigate to the **Code** tab (usually the first tab near the top of the repository page). This is where all the files for a project live.
+2. Review the list of files and folders provided in the repository.
+3. Locate the `README.md` file. In most projects, this file automatically displays at the bottom of the Code tab to provide a welcome message and instructions.
+
+</details>
+
+<details>
+<summary><b>Visual Studio Code</b></summary>
+
+1. Ensure you have cloned the repository (see [Pre-Workshop Setup](../docs/00-pre-workshop-setup.md)).
+2. Open the repository folder in VS Code.
+3. Open the **Explorer** view (`Ctrl+Shift+E` or `Cmd+Shift+E` on Mac). This is where all the files for a project live.
+4. Review the file list in the sidebar. Use the arrow keys to navigate and expand folders.
+5. Select the `README.md` file to open it in the editor.
+
+</details>
+
+<details>
+<summary><b>Command Line (GitHub CLI)</b></summary>
+
+1. Ensure you have `gh` installed and authenticated.
+2. Clone the repository: `gh repo clone [your-repo-name]`.
+3. Navigate into the folder: `cd [your-repo-name]`.
+4. List the files in the directory: `ls` (macOS/Linux/PowerShell) or `dir` (Windows).
+5. View the contents of the README: `gh repo view --readme` or `cat README.md`.
+
+</details>
+
+**Expected Outcome:**
+You have familiarized yourself with the repository layout and understand where to locate project files.
+
+**Troubleshooting (If you get stuck):**
+- **Feel lost?** Use your browser's "Go Back" function or select the repository name at the top left to return to the main page.
+-**Need more context?** Review [Chapter 2: Understanding GitHub](https://github.com/Community-Access/git-going-with-github/blob/main/docs/02-understanding-github.md).

+
+## Challenge 2: File Your First Issue
+
+**Title:** Challenge 2: File Your First Issue
+
+**Body:**
+**Magical! You have completed Challenge 1!**
+
+Welcome to your next step in the journey. Now that you have navigated the repository, it is time to practice communicating with your team using GitHub Issues. Issues are like a shared to-do list where teams discuss ideas, bugs, and tasks.
+
+**Your Goal:**
+File a new issue describing something you noticed in the repository. It can be a typo, an idea for improvement, or just a friendly greeting!
+
+**Step-by-Step:**
+
+<details>
+<summary><b>Web Browser</b></summary>
+
+1. Navigate to the **Issues** tab near the top of your repository page.
+2. Select the **New issue** button.
+3. If a template picker appears, choose the matching template by selecting **Get started**, or select **Open a blank issue** if no template fits.
+4. Provide a clear and descriptive **Title** for your issue (e.g., "Idea: Add a welcome banner").
+5. In the comment body field, write a sentence or two explaining your thought.
+6. Create the issue by selecting the **Submit new issue** button.
+
+</details>
+
+<details>
+<summary><b>Visual Studio Code</b></summary>
+
+1. Open the **GitHub Pull Requests and Issues** view from the Activity Bar, or open the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac).
+2. Open the issue creation form by selecting the `+` button in the **Issues** view, or run **GitHub Issues: Create Issue** from the Command Palette.
+3. Choose the current repository if prompted.
+4. Enter a descriptive title in the prompt bar.
+5. For the description, a scratchpad file will open. Type your thought there and save it to submit.
+
+</details>
+
+<details>
+<summary><b>Command Line (GitHub CLI)</b></summary>
+
+1. Run the interactive issue creator: `gh issue create`.
+2. Follow the prompts:
+   -**What would you like to do?**: Choose **"Create a new issue"**.
+   -**Title **: Enter a clear title (e.g., "Idea: Add a welcome banner").
+   -**Body **: Select **"Write with editor"** or **"Input text"** and type your sentence.
+   -**What's next?**: Select **"Submit"**.
+
+</details>
+
+**Expected Outcome:**
+The page will update to display your newly created issue with a unique number (like `#2`). Take a deep breath - you just started a conversation in open source!
+
+**Troubleshooting (If you get stuck):**
+- **Cannot find the New Issue button?** Ensure you are in the "Issues" tab, rather than Pull Requests or Actions.
+-**Unsure what to write?** Simply type "Hello World! This is my first issue."
+-**Need more context?** Review [Chapter 5: Working with Issues](https://github.com/Community-Access/git-going-with-github/blob/main/docs/05-working-with-issues.md).

+
+## Challenge 3: Join the Conversation
+
+**Title:** Challenge 3: Join the Conversation
+
+**Body:**
+**Excellent work! Challenge 2 is complete.**
+
+Communication in open source is all about collaboration. Sometimes you need to draw someone's attention to a specific issue. We accomplish this using `@mentions`.
+
+**Your Goal:**
+Mention Aria, your Workshop Agent, in a comment to ask for a workspace check.
+
+**Step-by-Step:**
+
+<details>
+<summary><b>Web Browser</b></summary>
+
+1. Navigate to the **Issues** tab and select an open issue.
+2. Navigate to the "Leave a comment" text area at the bottom of the issue thread.
+3. Type the `@` symbol followed by the handle `aria-bot`. A menu should appear to help you select a name.
+4. Add a friendly message like, "@aria-bot could you please check my work?"
+5. Send your comment by selecting the **Comment** button.
+
+</details>
+
+<details>
+<summary><b>Visual Studio Code</b></summary>
+
+1. Open the **GitHub Issues** panel.
+2. Use the arrow keys to choose your open issue from the list.
+3. In the issue's **Comment** text area, type `@aria-bot`. VS Code will often provide suggestions for you.
+4. Add your message: "@aria-bot could you please check my work?"
+5. Send your comment by selecting the **Comment** button or using `Ctrl+Enter` (`Cmd+Enter` on Mac).
+
+</details>
+
+<details>
+<summary><b>Command Line (GitHub CLI)</b></summary>
+
+1. Identify the issue number you want to comment on: `gh issue list`.
+2. Run the command to add a comment: `gh issue comment [issue-number] --body "@aria-bot could you please check my work?"`.
+3. Verify your comment was posted: `gh issue view [issue-number] --comments`.
+
+</details>
+
+**Expected Outcome:**
+Your comment will appear in the issue history, and Aria will receive a notification to review your progress.
+
+**Troubleshooting:**
+- **The menu did not appear?** Aria might be busy! Just type `@aria-bot` manually and post the comment.
+-**Want more details?** Review [Chapter 5: Working with Issues](https://github.com/Community-Access/git-going-with-github/blob/main/docs/05-working-with-issues.md).
+
+**To Unlock Challenge 4:**

+
+## Challenge 4: Branch Out
+
+**Title:** Challenge 4: Branch Out
+
+**Body:**
+**You are a communication pro! Let us get into the code.**
+
+In Git, a "branch" is a safe space to work on your ideas without affecting the main project. Think of it as a parallel universe where you can experiment! Aria is watching for new branches to help you along.
+
+**Your Goal:**
+Create a feature branch where you can safely make changes.
+
+**Step-by-Step:**
+
+<details>
+<summary><b>Web Browser</b></summary>
+
+1. Navigate to the **Code** tab.
+2. Locate the branch selector button (it currently indicates**main**).
+3. Access the dropdown and type a new name for your branch in the search box (e.g., `feature/my-first-edit`).
+4. Select the option that says **Create branch: [your-branch-name] from 'main'**.
+
+</details>
+
+<details>
+<summary><b>Visual Studio Code</b></summary>
+
+1. Open the **Source Control** view (`Ctrl+Shift+G` or `Cmd+Shift+G` on Mac).
+2. Use the arrow keys to focus the **Branch Name ** indicator in the Status Bar (bottom left) or open the **More Actions (...)** menu.
+3. Choose **Branch ** ->**Create Branch...**.
+4. Type your branch name: `feature/my-first-edit`.
+
+</details>
+
+<details>
+<summary><b>Command Line (Git)</b></summary>
+
+1. Create a new branch: `git checkout -b feature/my-first-edit`.
+2. Confirm you are on the new branch: `git branch`.
+3. Inform GitHub of your choice: `git push -u origin feature/my-first-edit`.
+
+</details>
+
+**Expected Outcome:**
+The page will refresh, and the branch selector will now display your new branch name instead of `main`. Aria will detect your new branch and is ready for your first commit!
+
+**Troubleshooting:**
+- **Forgot the name?** Don't worry, Aria can see all your branches.
+-**Branch name invalid?** Branch names cannot contain spaces. Use hyphens or underscores instead!
+-**Need more guidance?** Review [Chapter 4: The Learning Room](https://github.com/Community-Access/git-going-with-github/blob/main/docs/04-the-learning-room.md).
+
+**To Unlock Challenge 5:**
+Reply to this issue with your new branch name, and then activate **Close issue**!
+
+---
+
+## Challenge 5: Make Your Mark
+
+**Title:** Challenge 5: Make Your Mark
+
+**Body:**
+**Branch created! You are ready to make your mark.**
+
+Now that you have a safe branch, it is time to edit a file and save your changes. Saving changes in Git is called making a "commit." Aria can help review your commit messages for clarity!
+
+**Your Goal:**
+Edit a file in your repository and make a commit with a clear message. Ask Aria what she thinks of your message!
+
+**Step-by-Step:**
+
+<details>
+<summary><b>Web Browser</b></summary>
+
+1. Verify you are on the branch you just created (check the branch selector).
+2. Select a file you wish to edit (for example, the `README.md` file).
+3. Access the **Edit this file** button (pencil icon) to enter the editor.
+4. Make a small text change - add your name, fix a typo, or add a greeting.
+5. Provide a short, descriptive commit message in the summary box (e.g., "Add my name to the README").
+6. Save your changes by selecting the **Commit changes** button.
+
+</details>
+
+<details>
+<summary><b>Visual Studio Code</b></summary>
+
+1. Verify you are on the new branch (check the Status Bar).
+2. Open the `README.md` file (or another of your choice) from the Explorer.
+3. Make a change in the editor and save the file (`Ctrl+S` or `Cmd+S` on Mac).
+4. Stage your changes (this prepares them for your commit): Use the **Source Control ** view (`Ctrl+Shift+G` or `Cmd+Shift+G` on Mac). Use the arrow keys to focus your file and select the **Stage Changes ** icon (plus sign), or use the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and search for **"Git: Stage Changes"**.
+5. Type your commit message in the message field (e.g., "Add my name to the README").
+6. Finalize your commit: Select the **Commit ** button, use `Ctrl+Enter` (`Cmd+Enter` on Mac), or use the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and search for **"Git: Commit"**.
+7. Send your work to GitHub: Select the **Sync Changes ** or **Publish Branch ** button in the Source Control view, or use the Command Palette and search for **"Git: Push"**.
+
+</details>
+
+<details>
+<summary><b>Command Line (Git)</b></summary>
+
+1. Open your text editor and make a change to a file.
+2. Stage the file for your commit: `git add README.md`.
+3. Create your commit: `git commit -m "Add my name to the README"`.
+4. Send your changes to GitHub: `git push`.
+
+</details>
+
+**Expected Outcome:**
+Your changes are securely saved! If you want feedback on your message, mention `@aria-bot` in your next comment.
+
+**Troubleshooting:**
+- **Accidentally saved to the wrong branch?** Ask Aria or a facilitator for help.
+-**Want to read more?** [Chapter 4: The Learning Room](https://github.com/Community-Access/git-going-with-github/blob/main/docs/04-the-learning-room.md).

+
+## Challenge 6: Your First Pull Request
+
+**Title:** Challenge 6: Your First Pull Request
+
+**Body:**
+**Changes securely committed! Time to share them with the world.**
+
+A Pull Request (PR) is how you ask to merge your work. Aria will perform an automated "Aria Review" as soon as you open it!
+
+**Your Goal:**
+Open a Pull Request and let Aria run her first set of automated accessibility checks.
+
+**Step-by-Step:**
+
+<details>
+<summary><b>Web Browser</b></summary>
+
+1. Navigate to the **Pull requests** tab and choose **New pull request**.
+2. Ensure the *base* branch is `main` and *compare* is your feature branch.
+3. Choose **Create pull request** and give it a descriptive title.
+4. In the description field, type `Closes #1` (or your issue number). 
+5. Select **Create pull request** to submit.
+
+</details>
+
+<details>
+<summary><b>Visual Studio Code</b></summary>
+
+1. Open the **GitHub Pull Requests and Issues** view from the Activity Bar, or open the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac).

 ## What Is the Learning Room?
 
 The **Learning Room** is your **own private GitHub repository** for the workshop. When you accept the GitHub Classroom assignment in Block 0, GitHub copies the [`Community-Access/learning-room-template`](https://github.com/Community-Access/learning-room-template) repository into the workshop classroom organization as `<workshop-org>/learning-room-<your-username>`.

+## 6A. VS Code 1.120 Agents Window
+
+VS Code 1.120 adds the **Agents window** to Stable as a Preview feature. Agent mode is a way for Copilot to behave inside a session. The Agents window is a separate VS Code window for managing those sessions across projects.
+
+Use the normal Chat view when you are learning, editing one workspace, or using file selections from the editor. Use the Agents window when you want an agent-first dashboard: sessions on the left, chat in the center, customizations nearby, and changed files on the right.
+
+### Open the Agents Window
+
+1. Open the Command Palette with `Ctrl+Shift+P`.
+2. Run **Chat: Open Agents Window**.
+3. Sign in to GitHub if prompted.
+4. Select **New** or press `Ctrl+N`.
+5. Choose a workspace folder or GitHub repository.
+6. Choose the agent type, isolation mode, custom agent, and model if those controls are available to your account.
+7. Write a focused task and review the Changes panel before applying, committing, merging, or checking out the result.
+
+The following table shows when to stay in the editor and when to use the Agents window.
+
+| You Want To | Best Surface |
+| ----------- | ------------ |
+| Ask a question about the file you are reading | Chat view in the editor |
+| Use Accessible View to read one response carefully | Chat view in the editor |
+| Make a focused edit in the current workspace | Chat view with Agent mode |
+| Track several background or cloud sessions | Agents window |
+| Review a set of agent changes before merging | Agents window Changes panel |
+| Manage agents, skills, instructions, hooks, MCP servers, and plugins together | Agents window Customizations panel |
+
+### Safety Notes for Workshop Learners
+
+- Treat the Agents window as an advanced workflow surface. It helps you coordinate work, but it does not remove your responsibility to review changes.
+- Prefer worktree isolation for Copilot CLI sessions while learning. It keeps agent edits separate from your active workspace.
+- Use the Files panel sync button before starting a session when your branch may be behind upstream.
+- Read terminal command risk badges if enabled, but still inspect the full command before approving.
+- Run project validation tasks from the Agents window before accepting a completed session.
+- If a session changes more files than expected, stop and review before continuing.
+
+### Accessibility Notes
+
+**Screen reader users:** Open the Agents window through the Command Palette. Use `Alt+F1` for context-specific Accessibility Help, `F6` and `Shift+F6` to move between workbench parts, and `Alt+F2` for Accessible View when chat responses, terminal output, or diffs are too dense to follow live.
+
+**Low-vision users:** Increase zoom before opening dense multi-panel sessions. Use high-contrast themes, modal diff view, and wider panels when reviewing changes. If the Agents window needs different display settings than your editor, use Agents-window-specific settings overrides.
+
+**Sighted users:** Use the Sessions list as a dashboard and the Changes panel as your review gate. Changed-file counts, status badges, and diff views are the visual signals that tell you whether the agent stayed inside the requested scope.
+
+For the full 1.120 addendum, including terminal risk assessment, terminal output compression, Markdown preview diffs, BYOK model controls, and extension support in the Agents window, see [Appendix K: VS Code 1.120 Agents Window and Impactful Updates](appendix-k-copilot-reference.md#4a-vs-code-1120-agents-window-and-impactful-updates).

-## 1. The Capstone Challenge
+> **Challenge 16: Capstone Project.** This is the culminating challenge of the workshop. Your evidence can be a pull request, an agent file, a documented contribution plan, or a review-ready draft that shows clear purpose, responsibilities, and guardrails.
 
-The capstone is Challenge 16 -- the final challenge of the workshop. You will:
+## 1. The Capstone Project
 
-1. Choose a mission for a new accessibility agent (or improve an existing one)
-2. Write an agent file with valid YAML frontmatter
-3. Define clear responsibilities and guardrails
-4. Test the agent locally with GitHub Copilot
-5. Open a pull request from your fork to the upstream repository
-6. Respond to peer review feedback
+The capstone is bigger than one challenge and bigger than one repository. Challenge 16 is the checkpoint where you show evidence. The chapter is the project guide.
 
-This is not a simulation. Your pull request goes to a real repository. If your agent meets the quality bar, it will be merged and available to real users.
+You will:
 
-### What you need before starting
+1. Choose a repository where an agentic contribution would be useful.
+2. Identify a real audience and a real workflow gap.
+3. Create or improve an agent, prompt, custom instruction, skill, workflow, or documentation page that helps that repository.
+4. Define clear responsibilities and guardrails.
+5. Test the contribution locally or document how it should be tested.
+6. Open a pull request, prepare a review-ready branch, or write a contribution plan when you do not have repository access.
+7. Respond to review or describe what review feedback you would seek.
 
-- [ ] You have forked and cloned the accessibility-agents repository ([Chapter 18](18-fork-and-contribute.md))
-- [ ] You have a feature branch created: `agents/your-username-agent-name`
-- [ ] You understand how to push to your fork and open a PR ([Chapter 18](18-fork-and-contribute.md))
-- [ ] You have GitHub Copilot or Copilot Free active ([Chapter 16](16-github-copilot.md))
-- [ ] You have explored the existing agents in [Chapter 19](19-accessibility-agents.md)
+This is not a simulation. Your work should be useful to a real maintainer, even if it remains a draft during the workshop.
 
-### Time estimate
+### What Counts as a Capstone Contribution
 
-Most students complete the capstone in 60 to 90 minutes. The phases are designed so you can get a working agent in 30 minutes and spend the remaining time improving it.
+The following table lists valid capstone contribution types.
 
----
+| Contribution Type | Example | Evidence |
+| --- | --- | --- |
+| New agent | A GLOW agent that audits uploaded-document error messages for plain language | Agent file plus testing notes |
+| Improved agent | Better guardrails for an Accessibility Agents reviewer agent | Diff or PR link plus explanation |
+| Prompt or slash command | A prompt that guides maintainers through release-note updates | Prompt file plus example run |
+| Custom instructions | Repo-specific instructions that prevent inaccessible UI patterns | Instructions file plus scope explanation |
+| Skill or rule reference | A reusable rule pack for large-print document checks | Skill draft plus source notes |
+| Documentation update | A contribution guide that explains how to add agents safely | PR link or review-ready draft |
+| Issue triage plan | A scoped proposal for an agent the project should build next | Issue draft with mission, impact, and guardrails |
 
-## 2. Phase 1: Choose Your Agent's Mission
+### What You Need Before Starting
 
-> **See also:** [Chapter 19: Accessibility Agents](19-accessibility-agents.md) introduces the agent ecosystem and shows existing agents for inspiration.
+- [ ] You understand the fork, branch, commit, push, and PR workflow from [Chapter 18](18-fork-and-contribute.md).
+- [ ] You have GitHub Copilot or Copilot Free active from [Chapter 16](16-github-copilot.md).
+- [ ] You have explored Accessibility Agents in [Chapter 19](19-accessibility-agents.md), even if you choose a different capstone repository.
+- [ ] You know which repository you want to help and why.
+- [ ] You can explain the impact of your contribution in one or two sentences.
 
-### What makes a good agent mission
+### Time Estimate
 
-A good agent solves a specific, recurring problem. It does not try to do everything. Consider these questions:
+Most students complete a workshop-ready capstone in 60 to 90 minutes. A polished pull request can take longer, especially when the target project has tests, review requirements, or unfamiliar architecture. It is acceptable to finish the workshop with a clear draft and continue asynchronously.
 
-- **What task do you repeat?** Think about workflow steps from Day 1 and Day 2 that felt repetitive.
-- **What would a specialist know?** An agent works best when it has deep knowledge of a focused area.
-- **What gap exists?** Look at the existing agents in [Chapter 19](19-accessibility-agents.md). Is there a workflow that no agent covers?
+---
 
-### Mission categories to consider
+## 2. Choose Your Contribution Path
 
-| Category | Example missions | Existing agents in this space |
-|---|---|---|
-| Accessibility auditing | Audit color contrast in CSS variables, check form labels, validate heading hierarchy | contrast-master, forms-specialist, alt-text-headings |
-| Document accessibility | Check PDF reading order, audit Excel sheet names, validate Word heading structure | pdf-accessibility, excel-accessibility, word-accessibility |
-| GitHub workflow | Summarize notifications, track stale issues, generate release notes | daily-briefing, issue-tracker, analytics |
-| Developer tools | Validate agent files, lint markdown for accessibility, check keyboard navigation | testing-coach, link-checker, markdown-a11y-assistant |
-| Education | Explain a WCAG criterion, generate quiz questions, summarize a chapter | wcag-guide |
+Freedom is encouraged. Choose a repository where your work can be genuinely useful.
 
-### Write your mission statement
+The following table compares the recommended paths.
 
-Before writing any code, write a one-sentence mission statement:
+| Path | Best For | Good Contribution Ideas |
+| --- | --- | --- |
+| Accessibility Agents | Learners who want the most direct agent-building path | Add a focused agent, improve guardrails, update docs, refine prompts, improve skills |
+| GLOW | Learners interested in document accessibility, large print, Office files, web apps, desktop apps, or user workflows | Add a GLOW-focused agent, improve `.github` customizations, document contributor workflows, propose rule coverage |
+| Another repository | Learners with a project they already care about | Add project-specific custom instructions, an agent for maintainer workflows, accessible contribution docs, or issue templates |
 
-> "My agent helps [who] by [doing what] when [in what situation]."
+### Choosing Well
 
-Example: "My agent helps documentation authors by checking that all images in a markdown file have meaningful alt text when they open a file for review."
+Ask these questions before you choose:
 
-Write this statement in your challenge issue comment so your buddy and facilitator can give early feedback.
+- **Impact:** Who would benefit if this contribution were merged?
+- **Fit:** Does the repository already use agents, prompts, instructions, skills, or automation?
+- **Scope:** Can you make a useful change in one small pull request?
+- **Access:** Can you fork the repository or create a draft in your own fork?
+- **Safety:** Can you define guardrails that prevent the agent from overreaching?
 
 ---
 
-## 3. Phase 2: Write the Agent File
+## 3. Project Option: Accessibility Agents
 
-An agent file is a Markdown file with YAML frontmatter that defines the agent's identity, and a body that contains the agent's instructions. Agent files live in the `.github/agents/` directory (for GitHub Copilot agents) or in team-specific directories in the accessibility-agents repository.
+[Accessibility Agents](https://github.com/Community-Access/accessibility-agents) is the default capstone path because it is built around agents, prompts, instructions, skills, and accessibility workflows.
 
-### File location and naming
-
-Create your agent file at:
-
-```text
-.github/agents/your-agent-name.md
-```
+Current local inventory checked May 13, 2026:
 
-Use lowercase with hyphens. Example: `.github/agents/alt-text-validator.md`
+| Asset Type | Count |
+| --- | ---: |
+| Agent files (`*.agent.md`) | 83 |
+| Prompt files (`*.prompt.md`) | 132 |
+| Instruction files (`*.instructions.md`) | 10 |
+| Skill files (`SKILL.md`) | 207 |

+### Why Choose Accessibility Agents
 
-Every agent file has two parts:
+- You want to build or improve an actual agent.
+- You want clear examples to copy and adapt.
+- You want your contribution to help accessibility reviewers, developers, document remediators, GitHub maintainers, or assistive technology users.
+- You want the Challenge 16 autograder path that validates agent frontmatter, responsibilities, and guardrails.
 
-1. **YAML frontmatter** -- metadata between `---` markers at the top of the file
-2. **Instructions body** -- Markdown content that tells the agent how to behave
+### Good Accessibility Agents Contributions
 
-### Minimal agent file template
+- Add a small specialist agent for an uncovered accessibility workflow.
+- Improve an existing agent's guardrails or output format.
+- Update stale counts, platform names, or release-note guidance in documentation.
+- Add examples that show how screen reader, low vision, keyboard-only, and sighted users should use an agent.
+- Improve prompt files so they produce more structured, reviewable output.
+- Improve a skill reference with clearer severity scoring or remediation guidance.
 
-```markdown
----
-name: "Alt Text Validator"
-description: "Checks that all images in markdown files have meaningful, non-placeholder alt text."
 ---
 
-# Alt Text Validator
-
-You are an accessibility specialist focused on image alt text quality in markdown documentation.
-
-## Responsibilities
-
-- Scan markdown files for images missing alt text
-- Identify placeholder alt text like "image", "screenshot", "photo", or empty strings
-- Suggest specific, descriptive alt text based on the image context
-- Flag decorative images that should use empty alt text (`alt=""`)
-
-## Guardrails
+## 4. Project Option: GLOW
 
-- Never modify files without explicit user approval
-- Always explain why alt text needs improvement before suggesting a replacement
-- Do not generate alt text for images you cannot see -- ask the user to describe the image
-- Limit scope to the files the user asks about -- do not scan the entire repository unprompted
-```
+[GLOW](https://github.com/Community-Access/glow) stands for **Guided Layout & Output Workflow**. It is a multi-surface accessibility toolkit for auditing, fixing, converting, and generating accessible documents. It includes a web app, desktop tooling, a CLI-oriented workflow, a VS Code agent toolkit, and a Word add-in path.
 
-### YAML frontmatter fields
+GLOW focuses on document accessibility and large-print production. It enforces the American Council of the Blind Large Print Guidelines, APH submission guidance, Microsoft Accessibility Checker-style checks, and WCAG 2.2 AA concepts across formats such as Word, Excel, PowerPoint, Markdown, PDF, EPUB, HTML, and CSS.
 
-| Field | Required | Description |
-|---|---|---|
-| `name` | Yes | Display name for the agent (title case, spaces allowed) |
-| `description` | Yes | One-sentence description of what the agent does -- also drives **automatic invocation**: Copilot matches this text against your request and delegates to the agent without you selecting it manually |
+Current local inventory checked May 13, 2026:
 
-> **Write a strong description.** Vague descriptions result in missed automatic routing.
->
-> - Weak: `Helps with accessibility`
-> - Strong: `Checks markdown files for accessibility issues, fixes descriptive links and heading hierarchy, and flags alt text for human review`
->
-> The more specific the description, the more reliably Copilot invokes the right agent for the right task.
+| Asset Type | Count |
+| --- | ---: |
+| Agent files (`*.agent.md`) | 5 |
+| Prompt files (`*.prompt.md`) | 5 |
+| Instruction files (`*.instructions.md`) | 1 |
+| Skill files (`SKILL.md`) | 1 |
 
-### Writing the instructions body
+### What GLOW Does
 
-The instructions body tells the agent how to behave. Write it as if you are briefing a new team member on their first day:
+- Audits Word, Excel, PowerPoint, Markdown, PDF, EPUB, HTML, and CSS for accessibility issues.
+- Auto-fixes Word document issues where the change is deterministic, such as fonts, spacing, emphasis, headings, and margins.
+- Generates ACB-compliant Word templates.
+- Converts documents to Markdown, accessible HTML, Word, EPUB 3, PDF, and DAISY-oriented outputs through MarkItDown, Pandoc, LibreOffice, and related tooling.
+- Provides web, desktop, CLI, VS Code, and Word add-in surfaces.
+- Supports standards profiles such as ACB 2025 Baseline, APH Submission, and Combined Strict.
 
-- **Start with identity.** "You are a [role] focused on [area]."
-- **List responsibilities.** What specific tasks does this agent handle?
-- **Set guardrails.** What should the agent never do? What are its limits?
-- **Provide examples.** Show what good output looks like.
+### Why Choose GLOW
 
-> **Screen reader note:** The agent file is plain Markdown. There are no special tools needed to write it. Use any text editor.
+- You care about documents, large print, Office files, or accessible publishing.
+- You want a smaller agent surface where one contribution can make a visible difference.
+- You want to connect agents to a real product workflow: upload, audit, fix, convert, template, export, review.
+- You want to help users who may not think of themselves as developers.
 
-### Learning Cards: Writing the Agent File
+### Good GLOW Contributions
 
-<details>
-<summary>Screen reader users</summary>
+- Add a GLOW agent that helps users choose between Audit, Fix, Template, Export, and Convert workflows.
+- Improve the existing large-print agent instructions with clearer responsibilities and guardrails.
+- Add a prompt for reviewing release notes against current GLOW features.
+- Add custom instructions for web UI accessibility, plain-language findings, or large-print documentation consistency.
+- Write documentation that explains how contributors should test document accessibility changes.
+- Draft an issue for a future agent, such as a plain-language findings reviewer, batch-audit triage assistant, or Word add-in accessibility reviewer.
 
-- Create your agent file with `Ctrl+N`, then `Ctrl+S` and save to `.github/agents/your-agent-name.md` -- the Explorer navigates to the folder automatically
-- Use `Ctrl+Shift+O` to navigate between YAML frontmatter fields and Markdown headings (Responsibilities, Guardrails) in your agent file
-- The YAML frontmatter is between `---` markers at the top -- your screen reader announces these as horizontal rules
+### GLOW Safety Notes
 
-</details>
-
-<details>
-<summary>Low vision users</summary>
-
-- Agent files are standard Markdown -- open Markdown Preview (`Ctrl+Shift+V`) side by side to verify formatting as you write
-- The YAML frontmatter at the top uses `name:` and `description:` fields -- keep these on separate lines for readability at high zoom
-- Use a consistent heading hierarchy (# for title, ## for sections) so the Outline view (`Ctrl+Shift+O`) shows a clean structure
-
-</details>
-
-<details>
-<summary>Sighted users</summary>
-
-- Agent files follow a standard pattern: YAML frontmatter at the top, then identity statement, responsibilities, guardrails, and examples
-- Use the Outline view (`Ctrl+Shift+O`) to see your agent file's structure at a glance and navigate between sections
-- Copy the template from this chapter as a starting point -- replace the placeholder content with your agent's specific instructions
-
-</details>
+- GLOW handles documents that may contain personal, educational, medical, or organizational information. Do not put private user documents into public prompts or issues.
+- Auto-fix workflows must be conservative. An agent should explain proposed fixes and preserve author intent.
+- Large-print rules can affect pagination and layout. Document tradeoffs instead of pretending every fix is neutral.
+- When a rule comes from ACB, APH, Microsoft Accessibility Checker, or WCAG, cite the source or name the profile.
 
 ---
 
-## 4. Phase 3: Define Responsibilities and Guardrails
-
-Responsibilities and guardrails are the most important parts of your agent's instructions. The autograder checks that both sections exist.
+## 5. Project Option: Another Repository
 
-### Writing responsibilities
+You may choose another repository if the contribution is meaningful and reviewable. This can be your own project, a classmate's project, a community repository, or another open source project you care about.
 
-Responsibilities define what the agent does. Be specific and actionable:
+### Requirements for Another Repository
 
-**Good responsibilities (specific):**
+- The work must help the repository, not just satisfy the workshop.
+- The contribution must have a clear audience.
+- The contribution must be small enough to review.
+- The contribution must include responsibilities and guardrails when it involves an agent or automated workflow.
+- If you cannot open a pull request, write a review-ready issue or contribution plan instead.
 
-- Scan HTML files for `<img>` tags missing the `alt` attribute
-- Check that all `<button>` elements have visible text or an `aria-label`
-- Verify heading levels do not skip (e.g., `h1` to `h3` without `h2`)
+### Good Contributions in Any Repository
 
-**Weak responsibilities (vague):**
+- Add `.github/copilot-instructions.md` that teaches Copilot the project's accessibility and contribution standards.
+- Add a custom agent for triaging issues, reviewing docs, checking release notes, or auditing accessibility.
+- Add a prompt file for a repeated maintainer task.
+- Improve issue templates or PR templates so contributors provide better accessibility context.
+- Write contributor documentation that explains how to test with keyboard, screen reader, and high contrast workflows.
 
-- Help with accessibility
-- Check code
-- Find problems
+---
 
-Each responsibility should describe one discrete action the agent can take.
+## 6. Define Your Mission
 
-### Writing guardrails
+A good capstone mission solves a specific, recurring problem. It does not try to do everything.
 
-Guardrails define what the agent must not do. They prevent the agent from overstepping, giving harmful advice, or acting without permission:
+Write a one-sentence mission statement before editing files:
 
-**Good guardrails:**
+> "My contribution helps [who] by [doing what] when [in what situation]."
 
-- Never auto-fix code without asking the user first
-- Do not provide medical, legal, or financial advice when discussing accessibility compliance
-- Limit reviews to the files the user specifies -- do not scan the entire repository
-- If a finding is uncertain, say so explicitly rather than presenting it as definitive
-- Do not remove existing accessibility attributes unless they are demonstrably incorrect
+Examples:
 
-**Why guardrails matter:** An agent without guardrails will confidently do things it should not. A contrast checker that silently changes your CSS colors is dangerous. A document reviewer that deletes "unnecessary" alt text is destructive. Guardrails are how you make an agent safe.
+- "My agent helps GLOW contributors by checking whether release notes describe user-facing document accessibility changes clearly."
+- "My prompt helps Accessibility Agents maintainers by turning a release note into repo documentation updates with screen reader, low vision, and sighted guidance."
+- "My custom instructions help my project avoid inaccessible React patterns when Copilot generates forms and dialogs."
 
-### Learning Cards: Responsibilities and Guardrails
+Post this mission statement in your Challenge 16 issue comment so a buddy or facilitator can give early feedback.
 
-<details>
-<summary>Screen reader users</summary>
+---
 
-- Use `## Responsibilities` and `## Guardrails` as exact heading names -- the autograder searches for these strings
-- Each responsibility should start with a verb (Scan, Check, Verify, Flag) -- this makes them concrete and testable
-- Guardrails should start with "Never" or "Do not" to set clear boundaries your screen reader identifies as restrictions when reviewing the file
+## 7. Write or Improve the Agentic Asset
 
-</details>
+Your asset may be an agent file, prompt file, instruction file, skill, or documentation update. If you are writing an agent, use the structure below.
 
-<details>
-<summary>Low vision users</summary>
-
-- Format responsibilities as a bulleted list (starting with `-`) for easy scanning at high zoom -- one responsibility per bullet
-- Keep each guardrail to a single line so it remains visible without horizontal scrolling at your zoom level
-- Use bold text for emphasis on critical guardrails (e.g., **Never modify files without approval**) to improve visual scanning
+### Agent File Location and Naming
 
-</details>
+Follow the target repository's conventions. Common locations include:
 
-<details>
-<summary>Sighted users</summary>
+```text
+.github/agents/your-agent-name.agent.md
+agents/your-agent-name.agent.md
+community-agents/your-agent-name.agent.md
+```
 
-- The autograder checks for "Responsibilities" and "Guardrails" headings -- use exactly these words as `## ` headings
-- Aim for 4-6 responsibilities and 3-5 guardrails -- too few makes the agent vague, too many makes it rigid
-- Compare your responsibilities against the example agents in Section 9 to calibrate specificity
+Use lowercase with hyphens. Example: `.github/agents/plain-language-findings.agent.md`.
 
-</details>
+### Minimal Agent File Template
 
+```markdown
+---
+name: "Plain Language Findings Reviewer"
+description: "Reviews accessibility audit findings for plain language, actionable remediation, and user impact."
 ---
 
-## 5. Phase 4: Test Your Agent Locally
-
-> **See also:** [Chapter 18: Fork and Contribute](18-fork-and-contribute.md) covers the fork-and-PR workflow you will use to submit your agent.
-
-Before opening a pull request, test your agent to verify it works.
+# Plain Language Findings Reviewer
 
-### Testing with GitHub Copilot Chat
+You are an accessibility documentation specialist focused on making audit findings clear, actionable, and respectful.
 
-1. Open VS Code with the accessibility-agents repository.
-2. Ensure your agent file is saved in `.github/agents/`.
-3. Open GitHub Copilot Chat (`Ctrl+Alt+I`) or run **Chat: Open Chat** from the Command Palette.
-4. Invoke your agent by name: `@your-agent-name check this file for accessibility issues`
-5. Observe the response. Does the agent:
-   - Understand its mission?
-   - Follow its responsibilities?
-   - Respect its guardrails?
+## Responsibilities
 
-### Testing checklist
+- Review finding text for plain language and specific remediation steps
+- Identify vague phrases that do not explain user impact
+- Check that findings name the affected workflow or assistive technology when known
+- Suggest revised wording without changing the technical meaning
 
-- [ ] The agent responds when invoked by name
-- [ ] The agent stays within its defined responsibilities
-- [ ] The agent does not violate any guardrails
-- [ ] The agent's output is useful and specific
-- [ ] The agent handles edge cases gracefully (empty files, no issues found)
+## Guardrails
 
-### Iterating on your agent
+- Never claim a finding is fixed unless the user provides verification evidence
+- Do not remove severity or WCAG references
+- If the technical meaning is unclear, ask for clarification instead of guessing
+- Preserve project terminology unless it is inaccurate or inaccessible
+```
 
-If the agent does not behave as expected:
+### YAML Frontmatter Fields
 
-1. Read its instructions carefully. Is anything ambiguous?
-2. Add more specific instructions or examples.
-3. Test again with the same prompt.
-4. Repeat until the behavior matches your intent.
+The following table describes the common agent frontmatter fields.
 
-Most students iterate 2-3 times before they are satisfied.
+| Field | Required | Description |
+| --- | --- | --- |
+| `name` | Yes | Display name for the agent |
+| `description` | Yes | One-sentence description of what the agent does and when it should be used |
+| `tools` | Project-specific | Tool list when the target platform requires explicit tools |

-## 8. Capstone Rubric
-
-The capstone is worth 60 autograded points plus peer review. Here is the complete rubric:
-
-### Autograded (60 points)
-
-| Criterion | Points | What the autograder checks |
-|---|---|---|
-| Agent file exists | 10 | A Markdown file exists in the agents directory |
-| Valid YAML frontmatter | 15 | File has `---` delimiters, `name` field, `description` field |
-| Responsibilities defined | 15 | A section with the heading "Responsibilities" exists and contains content |
-| Guardrails defined | 20 | A section with the heading "Guardrails" exists and contains content |
-
-### Peer review (qualitative)
-
-| Criterion | What reviewers assess |
-|---|---|
-| Mission clarity | Can a reader understand what the agent does in 10 seconds? |
-| Instruction quality | Are instructions specific enough that the agent behaves consistently? |
-| Guardrail coverage | Do the guardrails prevent the most obvious failure modes? |
-| Contribution standards | Does the PR follow the project's conventions and include a good description? |
+## 11. Capstone Rubric
 
-### What "meets expectations" looks like
+The capstone is assessed as a real contribution, not just as a file format exercise.
 
-A capstone that meets expectations has:
+### Core Criteria
 
-- A focused mission (not "help with accessibility" -- something specific)
-- At least 3 concrete responsibilities
-- At least 3 meaningful guardrails
-- A PR description that explains the agent's purpose
-- All autograder checks passing
+The following table lists the capstone evaluation criteria.
 
-### What "exceeds expectations" looks like
+| Criterion | Meets Expectations |
+| --- | --- |
+| Repository choice | The learner can explain why the chosen repository benefits from the contribution |
+| Mission clarity | The contribution has a focused mission statement |
+| Responsibilities | The agentic asset names concrete actions it should perform |
+| Guardrails | The contribution includes boundaries, limitations, or safety notes |
+| Accessibility impact | The work accounts for screen reader, low vision, keyboard-only, cognitive, or document accessibility needs when relevant |
+| Evidence | The learner provides a PR, draft, branch, issue, or contribution plan |
+| Review readiness | The contribution is small enough for someone else to review |
 
-A capstone that exceeds expectations also has:
+### What Exceeds Expectations Looks Like
 
-- Examples of expected input and output in the agent instructions
-- A section describing the agent's limitations
-- Evidence of testing (screenshots or transcripts in the PR description)
-- Thoughtful responses to review feedback
+- The contribution includes examples of expected input and output.
+- The PR description explains tradeoffs and limitations.
+- The learner tests with Copilot Chat or the VS Code Agents window and documents the result.
+- The learner responds thoughtfully to review feedback.
+- The contribution improves existing documentation, counts, or setup instructions alongside the agentic asset.

-## 9. Example Agents for Inspiration
-
-These examples show the range of valid agent designs. Your agent does not need to be this long, but it should be this clear.
-
-### Example 1: Heading Hierarchy Checker
-
-**Mission:** Validates that HTML and Markdown documents follow a correct heading hierarchy (no skipped levels).
-
-**Responsibilities:**
-
-- Scan files for heading elements (`h1` through `h6` in HTML, `#` through `######` in Markdown)
-- Report any instance where a heading level is skipped (e.g., `h2` followed by `h4`)
-- Suggest the correct heading level for each violation
-- Check that there is exactly one `h1` per page
-
-**Guardrails:**
-
-- Do not modify files -- only report findings
-- Do not change heading text, only heading levels
-- If a heading structure decision is ambiguous, present both options and let the user decide
-
-### Example 2: PR Description Quality Gate
-
-**Mission:** Reviews pull request descriptions to ensure they contain enough context for reviewers.
-
-**Responsibilities:**
-
-- Check that the PR description is at least 50 characters
-- Verify the description references an issue with `Closes #XX` or `Fixes #XX`
-- Check for a summary of changes made
-- Verify the description explains why the change was made, not just what was changed
-
-**Guardrails:**
-
-- Never approve or block a PR based solely on description quality
-- Do not rewrite the description for the author -- suggest improvements
-- Respect that different projects have different template requirements
-
-### Example 3: Keyboard Navigation Auditor
-
-**Mission:** Checks web components for keyboard accessibility compliance.
-
-**Responsibilities:**
-
-- Verify all interactive elements are reachable via Tab key
-- Check that custom components have appropriate `tabindex` values
-- Validate that focus order follows visual layout
-- Detect keyboard traps (elements that receive focus but cannot release it via keyboard)
-

-## 10. If You Get Stuck
+The following table lists common capstone blockers and recovery steps.
 
-| Problem | What to do |
-|---|---|
-| Cannot think of an agent idea | Look at the existing agents in [Chapter 19](19-accessibility-agents.md). What adjacent task is not covered? |
-| YAML frontmatter is invalid | Check that you have `---` on its own line at the start and end. Verify `name` and `description` are quoted strings. |
-| Autograder says "Responsibilities section not found" | Make sure you have a Markdown heading that says exactly `## Responsibilities`. |
-| Autograder says "Guardrails section not found" | Make sure you have a Markdown heading that says exactly `## Guardrails`. |
-| Agent does not respond in Copilot Chat | Verify the file is saved in `.github/agents/` and has a `.md` extension. Restart Copilot Chat. |
-| Agent ignores its guardrails | Add more explicit instructions. Instead of "be careful," say "Never do X under any circumstances." |
-| PR fails to open across forks | Verify you are comparing your fork's branch against the upstream's `main`. See [Chapter 18, Step 7](18-fork-and-contribute.md#9-step-7-open-a-pull-request). |
-| Reviewer feedback feels overwhelming | Address one comment at a time. Start with the smallest change. Reply to each comment individually. |
-| I finished but I am not sure I did it right | Compare your work against the [Challenge 16 reference solution](solutions/solution-16-capstone.md). If your agent file has valid frontmatter, responsibilities, and guardrails, you succeeded. |
+| Problem | What To Do |
+| --- | --- |
+| I cannot choose a repository | Choose Accessibility Agents if you want the clearest agent path, or GLOW if you want document accessibility and large-print impact |
+| I cannot think of an idea | Find one repeated maintainer task and write an agent or prompt for that task |
+| I do not have permission to open a PR | Create a draft in your fork or write a contribution issue with mission, responsibilities, and guardrails |
+| The repository has no agents yet | Add repo-level custom instructions or propose the first agent in a draft issue |
+| My agent does too much | Split the mission until it fits one sentence |
+| Copilot ignores the guardrails | Make the guardrails more explicit and test with the same prompt again |
+| The external project has different conventions | Follow that project's README and CONTRIBUTING file first, then explain any uncertainty in your PR |
+| I finished but I am not sure I did it right | Compare your work against the [Challenge 16 reference solution](solutions/solution-16-capstone.md), then ask for review |

-The capstone is where you design a small agent of your own and prepare it as a contribution. The important part is not a flashy idea. The important part is a clear purpose, useful responsibilities, and boundaries that keep the agent safe and honest.
+The capstone is where you choose a real repository and prepare an impactful agentic contribution. Accessibility Agents is the default path, GLOW is a strong document-accessibility path, and another project is valid when your contribution would genuinely help that repository. The important part is not a flashy idea. The important part is a clear purpose, useful responsibilities, and boundaries that keep the work safe and honest.
 
 **What to do:**
 
-1. Fork the [Community Access Accessibility Agents repository](https://github.com/Community-Access/accessibility-agents)
-2. Clone your fork and create a branch named `agent/YOUR-USERNAME`
-3. Write an `.agent.md` file with YAML frontmatter, responsibilities, and guardrails
-4. Push and open a cross-fork PR to the original repository
-5. Review a classmate's capstone PR when one is available
+1. Choose your target repository: [Accessibility Agents](https://github.com/Community-Access/accessibility-agents), [GLOW](https://github.com/Community-Access/glow), or another project you can explain.
+2. Write a one-sentence mission statement for the contribution.
+3. Create or improve an agent, prompt, instruction file, skill, workflow, or documentation page.
+4. Include responsibilities and guardrails when the contribution involves an agent or automation.
+5. Push and open a pull request, or prepare a review-ready branch, issue, or contribution plan if you do not have access.
+6. Review a classmate's capstone PR when one is available.
 
 Use the [agent file template](../learning-room/docs/samples/agent-file-template.md) and [fork workflow checklist](../learning-room/docs/samples/fork-workflow-checklist.md) for structure.
 
-**Evidence to post:** Link to your capstone PR or summarize the agent file you created. The autograder verifies required agent structure when the file is represented in the Learning Room.
+**Evidence to post:** Link to your capstone PR, branch, draft issue, or contribution plan. Include the repository you chose, the mission statement, what you changed or proposed, how you tested it, and the responsibilities and guardrails that make it safe.

 ### Organization (Org)
 
 An organization is a group account on GitHub that multiple people can belong to. Open source projects typically live inside an organization rather than under a personal account. For example: `https://github.com/microsoft/vscode` - here `microsoft` is the organization and `vscode` is the repository.
 
-
 ### Fork
 
 A fork is a personal copy of someone else's repository, living in your own GitHub account. When you fork a repo, you get all its files and history. Changes you make to your fork do not automatically affect the original. To propose your changes to the original project, you submit a pull request.
 
 **Why fork?** You do not have write access to most open source repos. Forking lets you work freely and then propose changes.

 Commands like `git push` and `git pull` default to using `origin` unless you specify otherwise.

 A branch is a separate line of development inside a repository. The main branch (often called `main` or `master`) holds the stable, released version of the project. When you want to add a feature or fix a bug, you create a new branch so your work doesn't affect `main` until it's ready.

 ### Diff
 
 A diff (short for difference) shows what changed between two versions of a file. Lines that were **added** are shown in green (with a `+` prefix). Lines that were **removed** are shown in red (with a `-` prefix). Lines that are unchanged are shown in grey for context.
 
 Reading diffs is one of the core skills for code review. When you view a Pull Request's "Files Changed" tab, you are reading a diff.

 A milestone groups issues and PRs toward a goal or deadline. For example: "v2.0 Release" or "Hackathon Day 1." Milestones show progress as a percentage of closed versus open items.
 
-
 ### Project (GitHub Projects)
 
 A GitHub Project is a flexible board for tracking work. It can show issues and PRs in table view, board view (kanban), or roadmap view. Projects are especially useful for hackathon-style coordination.
 
-
 ## Part 3: People and Roles
 
 ### Maintainer
 
 A maintainer is someone with write or admin access to a repository. Maintainers review PRs, triage issues, manage releases, and make decisions about the project's direction. Most open source projects have between one and five core maintainers.
 
-
 ### Contributor
 
 Anyone who contributes to an open source project is a contributor. Contributing includes code, documentation, design, testing, translation, issue triage, and community support. You do not need commit access to contribute.
 
-
 ### Triage
 
 Triaging issues means reviewing new issues to categorize them, add labels, assign them, close duplicates, and communicate with the reporter. Triage is an important contribution that doesn't require coding skills.
 
-
 ### Collaborator
 
 A collaborator is someone who has been explicitly granted write access to a repository. Collaborators can commit directly to the repo without forking (though good practice is still to use branches and PRs).

 **Warning:** Cherry-picking duplicates commits (creates a new commit with the same changes). Avoid cherry-picking commits that are part of an active feature branch - it causes confusion.
 
-
 ### Fetch vs Pull
 
 **`git fetch`** downloads changes from a remote repository but doesn't merge them into your current branch. It updates your local copy of remote branches (like `origin/main` or `upstream/main`) without touching your working files.
@@ -508,7 +478,6 @@ git pull origin main  # Fetch + merge origin/main into current branch
 
 **Best practice for collaboration:** Use `fetch` first, review with `git log origin/main`, then decide to merge or rebase.

 **Rule of thumb:** If you're not sure whether you need to force push, you probably shouldn't.
 
-
 ### SHA / Hash
 
 Every commit, file, and tree in Git is identified by a SHA hash - a 40-character string of letters and numbers (e.g., `a1b2c3d4e5f6...`). You will see shortened versions like `a1b2c3d` in the GitHub UI. These are unique fingerprints.
 
-
 ### Tag / Release
 
 A tag marks a specific commit as significant - usually a version release like `v1.0.0`. Tags are permanent references (unlike branches, which move with each new commit). GitHub Releases are built on top of tags and can include release notes and downloadable files.
 
-
 ### Actions / Workflow / CI/CD
 
 GitHub Actions is an automation platform built into GitHub. Workflows are automated scripts (written in YAML) that run in response to events - like a PR being opened or code being pushed. CI/CD stands for Continuous Integration / Continuous Deployment.
 
 In practice: when you open a PR, you will often see automated checks run (tests, linting, accessibility checks). These are GitHub Actions. See [GitHub Actions & Workflows](appendix-q-actions-workflows.md) for a full explanation.

 ### Webhook
 
 A webhook is an automated notification that GitHub sends to another service when something happens (a push, a PR opened, etc.). Webhooks power integrations with tools like Slack, project management systems, and CI services. As a contributor, you typically don't configure webhooks - they are set up by maintainers.
 
-
 ### GitHub Discussions
 
 Discussions are a threaded forum built into GitHub, separate from Issues. They are used for open-ended conversation, Q&A, and community announcements. Not all projects use Discussions - some prefer issues or external forums.
 
-
 ### Profile
 
 Your GitHub profile is your public identity. It shows your name, bio, location, repositories, contribution activity (the green squares), and pinned projects. Your profile URL is `https://github.com/your-username`.
 
-
 ### GitHub Copilot
 
 GitHub Copilot is an AI-powered coding assistant. It suggests code, documentation, and commit messages. In this workshop, we use Copilot to help write issue descriptions, PR descriptions, documentation, and code. See [GitHub Copilot](16-github-copilot.md) for the full walkthrough.

+## 8. VS Code 1.120 Chat, Agents Window, and Markdown Diff Updates
+
+VS Code 1.120 adds several accessibility-relevant changes for learners who use Copilot, review documentation diffs, or manage agent sessions. For the full Copilot and Agents window workflow, see [Appendix K: VS Code 1.120 Agents Window and Impactful Updates](appendix-k-copilot-reference.md#4a-vs-code-1120-agents-window-and-impactful-updates).
+
+### What Changed
+
+The following table summarizes the 1.120 changes that affect accessible VS Code workflows.
+
+| Feature | Accessibility Impact | Suggested Use |
+| ------- | -------------------- | ------------- |
+| Agents window, Preview | Gives agent sessions their own window with sessions, chat, customizations, files, and changes | Use Command Palette access, worktree isolation, and Changes panel review |
+| Terminal command risk assessment, Experimental | Adds a risk badge and command explanation to some terminal confirmations | Treat as extra context, not permission to skip reading the command |
+| Terminal output compression, Preview | Reduces long terminal output sent to chat, which can reduce context noise | Use for large diffs or install logs; ask for raw output when exact text matters |
+| Markdown preview for diffs, Preview | Lets documentation diffs render as Markdown instead of only source text | Useful for sighted and low-vision review of headings, lists, links, and tables |
+| Plan mode inline control | Lets supported agents show and edit plans inline before implementation | Useful when reviewing an agent plan before file changes start |
+| Model picker grouped by provider | Makes model lists easier to scan when many models are available | Keep beginners on Auto; use provider grouping for advanced model selection |
+| BYOK token usage and thinking effort | Gives advanced users more visibility and control for bring-your-own-key models | Not needed for beginners; useful for cost and context management |
+| Markdown HTML `id` completion and validation | Improves completion and validation for internal links to HTML IDs in Markdown | Helpful when maintaining long workshop docs with many anchors |
+| Smart select for Markdown tables | Expands selection from cell to row to whole table | Helpful for keyboard users editing large reference tables |
+
+### Screen Reader Workflow
+
+1. Open the Agents window with **Chat: Open Agents Window** from the Command Palette.
+2. Use `Alt+F1` in the focused area to find context-specific accessibility help.
+3. Use `F6` and `Shift+F6` to move among major workbench parts.
+4. Use `Alt+F2` for Accessible View when chat responses, terminal output, hovers, or diffs are easier to read in a stable buffer.
+5. Use `F7` and `Shift+F7` for diff navigation before accepting agent changes.
+6. When terminal risk assessment is enabled, listen to the risk label and explanation, then still read the exact command before approving it.
+
+### Low Vision Workflow
+
+1. Set zoom and theme before starting a dense Agents window session.
+2. Use modal diff view when side-by-side changes are too compressed.
+3. Try Markdown preview diffs for documentation changes where rendered headings, lists, and tables are easier to inspect.
+4. Widen the Sessions list, Chat area, and Changes panel as needed before reviewing work.
+5. Consider separate Agents window settings if your editor and agent review layouts need different zoom or density.
+
+### Sighted Workflow
+
+1. Use changed-file counts and session status badges as quick scope checks.
+2. Open each changed file from the Changes panel before accepting a session result.
+3. Use rendered Markdown diffs for documentation PRs and source diffs for syntax-sensitive edits.
+4. Use the integrated browser or terminal in the Agents window to validate generated work before committing or merging.
+
+### Settings Reference
+
+The following settings are useful to know when teaching VS Code 1.120 workflows.
+
+| Setting | What It Controls |
+| ------- | ---------------- |
+| `chat.tools.riskAssessment.enabled` | Shows risk assessment for terminal command confirmations |
+| `chat.tools.compressOutput.enabled` | Compresses large terminal output before it is sent to the model |
+| `chat.planWidget.inlineEditor.enabled` | Enables inline plan editing for supported agent flows |
+| `workbench.diffEditorAssociations` | Can set rendered Markdown preview as the default diff editor for Markdown |
+| `extensions.supportAgentsWindow` | Lets you opt specific installed extensions into the Agents window |
+| `chat.notifyWindowOnResponseReceived` | Controls OS notifications when chat responses arrive |
+| `chat.notifyWindowOnConfirmation` | Controls OS notifications when an agent needs confirmation |
+
+Example setting for rendered Markdown diffs:
+
+```json
+{
+  "workbench.diffEditorAssociations": {
+    "*.md": "vscode.markdown.preview.editor"
+  }
+}
+```

+## 4A. VS Code 1.120 Agents Window and Impactful Updates
+
+VS Code 1.120 brings the **Agents window** to Stable as a Preview feature. The Agents window is a dedicated VS Code window for agent-first work: you describe tasks, track multiple sessions, review changes, and move between projects without opening every project in a separate editor window.
+
+Use this section as the current 1.120 addendum for the workshop. The normal VS Code editor window remains the best place for hands-on editing, debugging, and learning the manual skills. The Agents window is best after you understand the workflow and want a central place to run, compare, and review agent sessions.
+
+### Agent Mode vs. Agents Window
+
+The following table distinguishes the related Copilot surfaces so learners do not confuse the mode with the window.
+
+| Concept | What It Means | Best Workshop Use |
+| ------- | ------------- | ----------------- |
+| Chat view in the editor | The Copilot Chat panel, editor tab, or chat window inside normal VS Code | Ask questions, use context from the active workspace, make focused changes while reading files |
+| Agent mode | The autonomous behavior inside a chat session where Copilot can read files, edit files, and request terminal commands | Complete a scoped task in one workspace after you know how to review its changes |
+| Copilot CLI session | A background agent session on your machine, often isolated in a Git worktree | Let an agent work on a well-defined task while you keep editing elsewhere |
+| Cloud agent session | A remote agent session connected to a GitHub repository and pull request workflow | Delegate a clear repository task that can be reviewed through a PR |
+| Agents window | A dedicated agent-first window that shows sessions, customizations, chat, files, and changes across projects | Manage multiple agent sessions and review agent work from one place |
+
+### How to Open the Agents Window
+
+Use any of these paths:
+
+1. Select **Open in Agents** from the VS Code title bar.
+2. Open the Command Palette and run **Chat: Open Agents Window**.
+3. Run `code --agents` from a terminal.
+
+If the title-bar button is distracting, right-click it and hide it. You can still use the Command Palette or `code --agents` later.
+
+### Interface Map
+
+The Agents window has four main areas.
+
+| Area | What It Contains | What To Check |
+| ---- | ---------------- | ------------- |
+| Sessions list | Current and past sessions across workspaces, grouped by project or time | Session name, status, workspace, agent type, file-change count |
+| Customizations panel | Agents, skills, instructions, hooks, MCP servers, and plugins | Which instructions and tools will shape the agent's behavior |
+| Chat area | The prompt and conversation for the selected session | The task request, clarifying questions, plans, and agent progress |
+| Changes panel | Files tab and Changes tab for the current session | Added, modified, deleted files, diffs, feedback, discard, commit, merge, or checkout actions |
+
+### Safe First Workflow
+
+1. Open the Agents window with **Chat: Open Agents Window**.
+2. Select **New** or press `Ctrl+N`.
+3. Choose the workspace folder or GitHub repository.
+4. If asked, trust the folder only when you recognize the project and understand what code may run.
+5. Choose the agent target and agent. For a first exercise, choose a narrow task and avoid broad autonomy.
+6. Prefer **worktree isolation** for Copilot CLI sessions when the project is a Git repository. Worktree isolation keeps agent edits separate from your active workspace until you review and merge them.
+7. Use the Files panel sync button before the agent starts when you need current upstream changes.
+8. Type one clear task. Example: `Review docs/16-github-copilot.md for references that are outdated after VS Code 1.120. Suggest changes before editing.`
+9. Review the Changes tab before committing, merging, applying, or checking out anything.
+10. Run a task, build, or test from the Tasks dropdown if the project has one.
+
+### Reviewing Agent Changes
+
+The Changes panel is the most important safety surface in the Agents window. Select a changed file to open a diff. Use the diff toolbar to switch between side-by-side, inline, embedded, or modal review modes. When an edit is not right, use **Add Feedback** in the diff or discard that edit from the Changes panel.
+
+Recommended review order:
+
+1. Read the agent's final summary.
+2. Open the Changes tab and count changed files.
+3. Review each diff before accepting the session result.
+4. Run available validation tasks.
+5. Commit, merge, apply, or checkout only after the changed files match the requested task.
+
+### Learning Cards: Agents Window
+
+<details>
+<summary>Screen reader users</summary>
+
+- Open the Agents window from the Command Palette with **Chat: Open Agents Window**; command search is usually faster than finding the title-bar button.
+- Use `Alt+F1` in the focused area to open Accessibility Help, then use `F6` and `Shift+F6` to move between major workbench areas.
+- Treat the Changes panel as required reading. Open each changed file, use `F7` and `Shift+F7` for diff navigation, and use `Alt+F2` when you need the Accessible View of a response, terminal output, or diff content.
+- Listen for approval prompts before terminal commands or broad permissions. Do not press `Enter` until you have heard the command and the action buttons.
+- Prefer worktree isolation while learning. It keeps agent edits away from your active folder until you intentionally merge them.
+
+</details>
+
+<details>
+<summary>Low vision users</summary>
+
+- Increase zoom before starting (`Ctrl+=`) and consider a high-contrast theme (`Ctrl+K Ctrl+T`) so the Sessions list, Changes panel, and diff colors remain readable.
+- Use modal diff view when side-by-side diffs feel cramped at high zoom.
+- Widen the Chat area and Changes panel before reviewing large sessions. The Agents window can become dense when multiple panels are visible.
+- If you need a different layout or font behavior in the Agents window than in your editor, override settings from the Agents window Settings editor.
+- Use the Markdown preview diff feature for documentation changes when visual structure is easier to review than raw Markdown syntax.
+
+</details>
+
+<details>
+<summary>Sighted users</summary>
+
+- Use the Sessions list as an agent work dashboard. Pin important sessions and filter when several tasks are running.
+- Watch changed-file counts before opening diffs. A small task that changes many files deserves extra review.
+- Use the Files panel to inspect the session workspace and the Changes tab to inspect only agent edits.
+- Use the integrated terminal and integrated browser in the Agents window to validate behavior before committing or merging.
+- Hide the Open in Agents title-bar button if it adds clutter; the Command Palette keeps the feature available.

+
+### Other VS Code 1.120 Changes Worth Calling Out
+
+The following VS Code 1.120 release-note items are most relevant to this workshop.
+
+| Feature | Why It Matters | Workshop Guidance |
+| ------- | -------------- | ----------------- |
+| Terminal command risk assessment, Experimental | Command confirmations can include a risk badge and a short explanation of what the command does | Useful for beginners and screen reader users, but still read the full command yourself before approving |
+| Terminal tool output compression, Preview | Long terminal output can be summarized before it enters chat context | Helpful for large `git diff`, install, and test logs; ask for raw output if exact lines matter |
+| Markdown preview for diffs, Preview | Markdown diffs can be reviewed as rendered content instead of only raw source | Useful for documentation PRs, especially when headings, lists, and tables matter visually |
+| Plan mode inline control for Claude and Copilot CLI | Plans can be edited inline before implementation starts | Use this when you want learners to shape the plan before the agent edits files |
+| BYOK token usage in Chat | Bring-your-own-key models now show more accurate context-window usage | Helpful for advanced users managing context and cost; not required for workshop beginners |
+| BYOK thinking effort controls | Reasoning models can expose thinking-effort settings from the model picker | Advanced setting only; leave defaults unless a facilitator gives specific guidance |
+| Model picker grouped by provider | Models are organized by provider and searchable by name | Tell learners to start with Auto and use provider grouping only when they must choose a specific model |
+| Copilot CLI plugin discovery | Plugins installed with GitHub Copilot CLI can be picked up by VS Code | Reduces duplicate setup for advanced agent users; document only as a convenience note |
+| Markdown HTML `id` completion and validation | Markdown links to HTML `id` anchors are easier to complete and validate | Useful for this repo because long docs use many internal anchors |
+| Smart selection for Markdown tables | Expand Selection can grow from a cell to a row and then the whole table | Helpful when editing large reference tables with keyboard or low vision workflows |
+
+### Recommended Settings to Know
+
+The following table lists settings that matter for this 1.120 update.
+
+| Setting | Status | What It Does |
+| ------- | ------ | ------------ |
+| `chat.tools.riskAssessment.enabled` | Experimental | Shows AI-generated risk labels for terminal command confirmations |
+| `chat.tools.compressOutput.enabled` | Preview | Compresses large terminal output before it is sent to the model |
+| `chat.planWidget.inlineEditor.enabled` | Current | Controls inline plan editing for supported agents |
+| `workbench.diffEditorAssociations` | Current | Can make Markdown files open with rendered Markdown preview diffs by default |
+| `extensions.supportAgentsWindow` | Preview | Opts specific installed extensions into the Agents window |
+| `chat.notifyWindowOnResponseReceived` | Current | Sends OS notifications when a chat response arrives |
+| `chat.notifyWindowOnConfirmation` | Current | Sends OS notifications when an agent needs input or confirmation |
+
+Example Markdown preview diff setting:
+
+```json
+{
+  "workbench.diffEditorAssociations": {
+    "*.md": "vscode.markdown.preview.editor"
+  }
+}
+```
+
+Example extension opt-in for the Agents window:
+
+```json
+{
+  "extensions.supportAgentsWindow": {
+    "publisher.extension-id": true
+  }
+}
+```
+
+### Limitations to Teach Explicitly
+
+- The Agents window is still a Preview feature in VS Code 1.120.
+- Not every agent type or third-party agent is supported in the Agents window yet.
+- Multi-root sessions are not supported in the Agents window yet.
+- Some extensions work automatically, but extension support is still evolving.
+- The agent cannot directly open the integrated browser for you; use a localhost link or **Browser: Open Integrated Browser**.
+- Organization policy can disable or limit agents, cloud agents, model choices, approvals, and BYOK features.
+
+### Recommended Placement in the Workshop
+
+Introduce the Agents window after learners complete the normal Chat and Agent mode flow in [Chapter 16](16-github-copilot.md). Treat it as an advanced navigation and review surface, not a replacement for learning Git, diffs, pull requests, and manual accessibility review.

+**Title:** Challenge 16: Capstone Project
 
 **Body:**
 **Welcome to your Capstone Challenge!**
 
-It is time to put everything you have learned together. You are going to build a new colleague for Aria!
+It is time to put everything you have learned together. You are going to choose a real repository and prepare an agentic contribution that could help real maintainers or users.
 
 **Your Goal:**
-Fork the `accessibility-agents` repository, design an original agent, and submit your PR for Aria's final review.
+Choose Accessibility Agents, GLOW, or another meaningful repository. Create or improve an agent, prompt, custom instruction, skill, workflow, documentation page, or contribution issue. Your evidence should show a clear mission, useful responsibilities, and guardrails.
 
 **Step-by-Step:**

 2. Select the **Code** button and choose the **Codespaces** tab.
-3. Once the environment loads, creating a new folder and a `.agent.md` file using the explorer.
-4. Add your agent's instructions, ensuring they follow the schema Aria uses.
-5. Create a new branch, commit, and submit a Pull Request to the original repository.
+3. Once the environment loads, create or update one focused contribution file using the Explorer.
+4. Add responsibilities and guardrails when your contribution involves an agent or automation.
+5. Create a new branch, commit, and submit a pull request when you have access.

+1. Fork your chosen repository when a fork-based contribution is possible.
 2. Clone your fork locally using `Git: Clone` from the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and open it.
-3. Create a new branch for your agent: `feature/new-agent-name`.
-4. Create a folder under `agents/` and a new file inside: `my-agent.agent.md`. Use the arrow keys in the Explorer to focus the parent folder.
+3. Create a new branch for your capstone: `capstone/your-username`.
+4. Create or update the agent, prompt, instruction, skill, workflow, documentation, or issue draft file. Use the arrow keys in the Explorer to focus the parent folder.
 5. Use the **Source Control** view (`Ctrl+Shift+G` or `Cmd+Shift+G` on Mac) to stage, commit, and publish your branch. Use the arrow keys to focus and select items.

 5. Push and open your PR: `git push` then `gh pr create`.
 
 </details>
 
 **Expected Outcome:**
-Aria will validate your agent's structure. Once approved, your new agent will join the `Community-Access` collection!
+You will have a review-ready contribution path: a PR, branch, draft issue, or contribution plan that explains who it helps, what it does, and how it stays safe.
 
 **Troubleshooting:**
 - **Workflow issues?** See [Chapter 18: Fork and Contribute](https://github.com/Community-Access/git-going-with-github/blob/main/docs/18-fork-and-contribute.md).
--**Need the agent schema?** See [Chapter 20: Build Your Own Agent](https://github.com/Community-Access/git-going-with-github/blob/main/docs/20-build-your-agent.md).
+- **Need capstone examples?** See [Chapter 20: Capstone Project](https://github.com/Community-Access/git-going-with-github/blob/main/docs/20-build-your-agent.md).
 
 **To Complete the Workshop:**
-Post the link to your Capstone PR here, then activate **Close issue**. 
-
-**CONGRATULATIONS!** Aria is thrilled to have a new teammate. You have completed the Git Going with GitHub workshop!
+Post the link to your capstone PR, branch, draft issue, or contribution plan here, then activate **Close issue**.

+
+| Tool | Minimum Version | Why It Matters |
+|------|-----------------|---|
+| **VS Code** | 1.113 | Accessibility Agents require latest Copilot Chat features |
+| **GitHub Copilot** | Latest (auto-updated) | Agents functionality depends on latest extension features |

 ## What Is the Learning Room?
 
 The **Learning Room** is your **own private GitHub repository** for the workshop. When you accept the GitHub Classroom assignment in Block 0, GitHub copies the [`Community-Access/learning-room-template`](https://github.com/Community-Access/learning-room-template) repository into the workshop classroom organization as `<workshop-org>/learning-room-<your-username>`. That copy is yours to use for the workshop - you have write access, your own branches, your own pull requests, and your own automated feedback from Aria the PR validation bot.

+## 6A. VS Code 1.120 Agents Window
+
+VS Code 1.120 adds the **Agents window** to Stable as a Preview feature. Agent mode is a way for Copilot to behave inside a session. The Agents window is a separate VS Code window for managing those sessions across projects.
+
+Use the normal Chat view when you are learning, editing one workspace, or using file selections from the editor. Use the Agents window when you want an agent-first dashboard: sessions on the left, chat in the center, customizations nearby, and changed files on the right.
+
+### Open the Agents Window
+
+1. Open the Command Palette with `Ctrl+Shift+P`.
+2. Run **Chat: Open Agents Window**.
+3. Sign in to GitHub if prompted.
+4. Select **New** or press `Ctrl+N`.
+5. Choose a workspace folder or GitHub repository.
+6. Choose the agent type, isolation mode, custom agent, and model if those controls are available to your account.
+7. Write a focused task and review the Changes panel before applying, committing, merging, or checking out the result.
+
+The following table shows when to stay in the editor and when to use the Agents window.
+
+| You Want To | Best Surface |
+| ----------- | ------------ |
+| Ask a question about the file you are reading | Chat view in the editor |
+| Use Accessible View to read one response carefully | Chat view in the editor |
+| Make a focused edit in the current workspace | Chat view with Agent mode |
+| Track several background or cloud sessions | Agents window |
+| Review a set of agent changes before merging | Agents window Changes panel |
+| Manage agents, skills, instructions, hooks, MCP servers, and plugins together | Agents window Customizations panel |
+
+### Safety Notes for Workshop Learners
+
+- Treat the Agents window as an advanced workflow surface. It helps you coordinate work, but it does not remove your responsibility to review changes.
+- Prefer worktree isolation for Copilot CLI sessions while learning. It keeps agent edits separate from your active workspace.
+- Use the Files panel sync button before starting a session when your branch may be behind upstream.
+- Read terminal command risk badges if enabled, but still inspect the full command before approving.
+- Run project validation tasks from the Agents window before accepting a completed session.
+- If a session changes more files than expected, stop and review before continuing.
+
+### Accessibility Notes
+
+**Screen reader users:** Open the Agents window through the Command Palette. Use `Alt+F1` for context-specific Accessibility Help, `F6` and `Shift+F6` to move between workbench parts, and `Alt+F2` for Accessible View when chat responses, terminal output, or diffs are too dense to follow live.
+
+**Low-vision users:** Increase zoom before opening dense multi-panel sessions. Use high-contrast themes, modal diff view, and wider panels when reviewing changes. If the Agents window needs different display settings than your editor, use Agents-window-specific settings overrides.
+
+**Sighted users:** Use the Sessions list as a dashboard and the Changes panel as your review gate. Changed-file counts, status badges, and diff views are the visual signals that tell you whether the agent stayed inside the requested scope.
+
+For the full 1.120 addendum, including terminal risk assessment, terminal output compression, Markdown preview diffs, BYOK model controls, and extension support in the Agents window, see [Appendix K: VS Code 1.120 Agents Window and Impactful Updates](appendix-k-copilot-reference.md#4a-vs-code-1120-agents-window-and-impactful-updates).

 ## 7. Next Edit Suggestions
 
 Next Edit Suggestions (NES) is a feature where Copilot watches what you're editing and predicts **where you'll need to make your next change** — then offers to make it for you. Unlike regular inline suggestions that complete what you're currently typing, NES looks ahead to related edits elsewhere in the file.

+## 11. Smart Actions and Advanced Copilot Features (VS Code 1.120+)
+
+VS Code 1.120 (May 2026) introduced several new Copilot features that accelerate common coding tasks without requiring explicit chat prompts.
+
+### Smart Actions
+
+**Smart Actions** are AI-powered suggestions for common tasks like generating commit messages, renaming symbols, fixing errors, and searching for related code semantically. They appear when you click the lightbulb icon (`Ctrl+.`) or interact with errors.
+
+Common Smart Actions:
+- **Generate Commit Message** - Turn staged changes into a descriptive commit message
+- **Rename Symbol** - Rename a variable or function and all references at once
+- **Fix Error** - Get suggestions to fix compilation, lint, or test errors
+- **Semantic Search** - Find conceptually related code (not just text matches)
+
+See [Appendix K: Smart Actions](appendix-k-copilot-reference.md#4c-smart-actions) for full keyboard shortcuts, workflows for all accessibility profiles, and workshop guidance.
+
+### Browser Agent (Experimental)
+
+The **Browser Agent** (experimental) lets your Copilot agent test and validate web applications directly. It can open your app in the integrated browser, verify features, check layouts, and take screenshots.
+
+This is useful for testing accessibility, validating responsive designs, and documenting features visually.
+
+See [Appendix K: Browser Agent (Experimental)](appendix-k-copilot-reference.md#4d-browser-agent-experimental) for examples, accessibility workflows, and testing best practices.
+
+### Plan Agent and Copilot Spaces
+
+The **Plan Agent** breaks complex tasks into step-by-step plans you can review and refine before implementation. **Copilot Spaces** let teams create shared knowledge bases that Copilot uses for more accurate, context-aware answers.
+
+These are advanced features for team workflows and complex refactoring. See [Appendix K: Plan Agent](appendix-k-copilot-reference.md#4e-plan-agent) and [Appendix K: Copilot Spaces](appendix-k-copilot-reference.md#4f-copilot-spaces---team-knowledge-base).
+
+### Copilot Pricing and Free Plan
+
+As of June 1, 2026, GitHub Copilot uses usage-based billing with GitHub AI Credits ($0.01 per credit). Copilot Free is available with monthly usage limits suitable for learning and light use.
+
+- **Free plan:** 50 completions and 2K chat tokens per month
+- **Pro plan:** $10/month, unlimited completions and higher chat limits
+- **Pro+ plan:** $39/month, agents and cloud features included
+
+See [Appendix K: Copilot Pricing, Free Plan, and Usage Limits](appendix-k-copilot-reference.md#15-copilot-pricing-free-plan-and-usage-limits) for detailed plan comparison, workshop guidance, and usage management tips.
+
+For complete reference material on all Copilot features, keyboard shortcuts, screen reader workflows, and customization, see [Appendix K: Copilot Reference](appendix-k-copilot-reference.md).

This chapter introduces the full landscape. Explore the agents that match your interests and workflows - there is no fixed subset you are required to use.
 >
 > **The agents are only useful if you have already done the work manually.** An agent that summarizes issues is useless to someone who has never read an issue. An agent that reviews a diff is useless to someone who has never read a diff. The agent does not teach you the skill - it multiplies a skill you already have.
 >
 > Day 1 built those skills. This chapter shows how to amplify them with automation - and how you can contribute new agents, improve existing ones, and shape the project's future.
 
+> **VS Code 1.120 note:** The Agents window is now available in VS Code Stable as a Preview feature. It does not replace custom Accessibility Agents. It gives you a dedicated window for running, reviewing, and organizing agent sessions across projects. Learn custom agents here, then use the Agents window when you want a single place to manage sessions, changed files, customizations, and validation tasks.

+## 3A. Multi-Platform Deployment - Beyond VS Code
+
+Chapter 16 introduced GitHub Copilot running in VS Code. But Accessibility Agents run on **five platforms**, each with its own setup, capabilities, and workflow. This section shows you when to use each platform and how to choose.
+
+### The Five Platforms: When to Use Each
+
+| Platform | Best For | Installation Time | Learning Curve |
+|----------|----------|-------------------|-----------------|
+| **GitHub Copilot (VS Code)** | Full-time development, web work, accessibility audits | 5 min | Low (familiar IDE) |
+| **Claude Code (CLI)** | Fast iteration, scripting, quick experiments | 2 min | Low (command line) |
+| **Gemini CLI** | Free tier accessibility, Google Search integration | 2 min | Low (command line) |
+| **Claude Desktop** | Extended context, longer sessions, offline work | 5 min | Low (GUI) |
+| **Codex CLI** | Experimental features, TOML configuration | 3 min | Medium (TOML syntax) |
+
+### Platform Comparison: Key Capabilities
+
+| Feature | Copilot | Claude Code | Gemini | Desktop | Codex |
+|---------|---------|-------------|--------|---------|-------|
+| **Web accessibility audit** | Yes | Yes | Yes | Yes | Yes |
+| **Document remediation** | Yes | Yes | Yes | Yes | No |
+| **GitHub integration** | Native | Yes | Limited | Yes | Yes |
+| **Keyboard-only use** | Full | Full | Full | Partial | Full |
+| **Screen reader support** | Strong | Strong | Good | Good | Strong |
+| **Cost** | Copilot subscription | Claude Pro | Free tier available | Claude Pro | Free |
+
+### Getting Started on Each Platform
+
+#### Option 1: Start with GitHub Copilot (Recommended for Most Users)
+
+You already have Copilot if VS Code is installed. No additional setup needed.
+
+**To start using agents right now:**
+1. Open VS Code
+2. Press `Ctrl+Alt+I` (or **View → Copilot Chat**)
+3. Type `@daily-briefing morning briefing`
+4. Read the result in the Chat panel
+
+**Next step:** Follow the challenges in Section 4 below. All examples assume Copilot in VS Code unless noted otherwise.
+
+#### Option 2: Use Claude Code for Faster Iteration
+
+Claude Code runs on the command line and offers free tier access (for certain Claude models).
+
+**Quick start:**
+```bash
+npm install -g @anthropic-ai/claude-code
+claude code auth
+claude code @daily-briefing morning briefing
+```
+
+**When to prefer Claude Code:**
+- You want to test agents without VS Code
+- You prefer terminal workflows
+- You want quick command-line experimentation
+
+**Full setup:** See [Appendix AA: Installation & Setup - Claude Code](appendix-aa-agent-installation-setup.md#claude-code).
+
+#### Option 3: Use Gemini CLI for Free Accessibility
+
+Gemini CLI offers **free tier access** to Gemini models with built-in Google Search.
+
+**Quick start:**
+```bash
+npm install -g @google/gemini-cli
+gemini config set api-key YOUR_API_KEY  # Get free key at ai.google.dev
+gemini @daily-briefing morning briefing
+```
+
+**When to prefer Gemini:**
+- Budget is a priority
+- You want Google Search integrated with agent responses
+- You prefer lightweight CLI tools
+
+**Full setup:** See [Appendix AA: Installation & Setup - Gemini CLI](appendix-aa-agent-installation-setup.md#gemini-cli).
+
+#### Option 4: Use Claude Desktop for Long Sessions
+
+Claude Desktop is the native Claude application with extended context windows and offline capability.
+
+**When to prefer Claude Desktop:**
+- Working on large documents or codebases
+- Need longer conversation context (200K tokens+)
+- Offline work on the plane
+- MCP server integration for custom tools
+
+**Full setup:** See [Appendix AA: Installation & Setup - Claude Desktop](appendix-aa-agent-installation-setup.md#claude-desktop).
+
+### Choosing Your Primary Platform
+
+**Decision tree:**
+
+1. **Do you already use VS Code daily?**
+   - Yes → Use **GitHub Copilot (VS Code)** - it's already there
+   - No → Continue to #2
+
+2. **Do you have a Copilot or Claude subscription?**
+   - Yes → Use **Claude Desktop** for longer sessions or Claude Code for CLI
+   - No → Continue to #3
+
+3. **Do you prefer CLI or GUI?**
+   - CLI → Use **Gemini CLI** (free) or **Claude Code**
+   - GUI → Use **Claude Desktop**
+
+4. **Are you exploring experimental features?**
+   - Yes → Try **Codex CLI** (TOML-based configuration)
+   - No → Pick one of the above
+
+### Running the Same Agent on Multiple Platforms
+
+All agents work the same across platforms, but the workflow differs slightly.
+
+**Example: Run `@aria-specialist` on all five platforms**
+
+**GitHub Copilot (VS Code):**
+```
+Ctrl+Alt+I → Type: @aria-specialist audit this component for ARIA
+```
+
+**Claude Code:**
+```bash
+claude code @aria-specialist audit this component for ARIA
+```
+
+**Gemini CLI:**
+```bash
+gemini @aria-specialist audit this component for ARIA
+```
+
+**Claude Desktop:**
+```
+Open chat → Type: @aria-specialist audit this component for ARIA
+```
+
+**Codex CLI:**
+```bash
+codex run @aria-specialist --task "audit this component for ARIA"
+```
+
+**Result:** All five produce similar accessibility findings, but with platform-specific presentation (VS Code sidebar, terminal, or GUI chat window).
+
+### Learning Paths by Platform
+
+#### Path A: "I use VS Code" (Recommended)
+1. Install Copilot extension (automatic)
+2. Complete all challenges in Section 4 using Copilot Chat
+3. Optionally try Claude Desktop for longer sessions
+4. Explore Appendices AA, AB, AC for advanced features
+
+#### Path B: "I prefer command line"
+1. Install Claude Code CLI: `npm install -g @anthropic-ai/claude-code`
+2. Run agents from terminal
+3. Use Gemini CLI for free tier experimentation
+4. Refer to Appendix AB for hooks and scripting
+
+#### Path C: "I want the best of both"
+1. Use Copilot in VS Code for daily work
+2. Install Claude Desktop for long-context projects
+3. Keep Gemini CLI for quick experiments
+4. Switch between platforms as needed per task
+
+### Screen Reader, Low Vision, and Keyboard Navigation by Platform
+
+**GitHub Copilot (VS Code):**
+- Screen readers: Full support in Chat panel; use `Ctrl+Alt+I` to open
+- Low vision: Zoom independently with `Ctrl+=`; use High Contrast theme

This is a real contribution to a real project -- your agent will join the roster of 55+ agents serving 3 accessibility teams across 5 platforms.
+> Everything you have learned comes together here. You will choose a real repository, design or improve an agentic contribution, test it, and prepare a pull request or contribution plan that would help that project. Accessibility Agents is still a strong default path, but it is not the only valid path.

-1. Choose a mission for a new accessibility agent (or improve an existing one)
-2. Write an agent file with valid YAML frontmatter
-3. Define clear responsibilities and guardrails
-4. Test the agent locally with GitHub Copilot
-5. Open a pull request from your fork to the upstream repository
-6. Respond to peer review feedback
+The capstone is bigger than one challenge and bigger than one repository. Challenge 16 is the checkpoint where you show evidence. The chapter is the project guide.
 
-This is not a simulation. Your pull request goes to a real repository. If your agent meets the quality bar, it will be merged and available to real users.
+You will:
 
-### What you need before starting
+1. Choose a repository where an agentic contribution would be useful.
+2. Identify a real audience and a real workflow gap.
+3. Create or improve an agent, prompt, custom instruction, skill, workflow, or documentation page that helps that repository.
+4. Define clear responsibilities and guardrails.
+5. Test the contribution locally or document how it should be tested.
+6. Open a pull request, prepare a review-ready branch, or write a contribution plan when you do not have repository access.
+7. Respond to review or describe what review feedback you would seek.
 
-- [ ] You have forked and cloned the accessibility-agents repository ([Chapter 18](18-fork-and-contribute.md))
-- [ ] You have a feature branch created: `agents/your-username-agent-name`
-- [ ] You understand how to push to your fork and open a PR ([Chapter 18](18-fork-and-contribute.md))
-- [ ] You have GitHub Copilot or Copilot Free active ([Chapter 16](16-github-copilot.md))
-- [ ] You have explored the existing agents in [Chapter 19](19-accessibility-agents.md)
+This is not a simulation. Your work should be useful to a real maintainer, even if it remains a draft during the workshop.
 
-### Time estimate
+### What Counts as a Capstone Contribution
 
-Most students complete the capstone in 60 to 90 minutes. The phases are designed so you can get a working agent in 30 minutes and spend the remaining time improving it.
+The following table lists valid capstone contribution types.
 
----
+| Contribution Type | Example | Evidence |
+| --- | --- | --- |
+| New agent | A GLOW agent that audits uploaded-document error messages for plain language | Agent file plus testing notes |
+| Improved agent | Better guardrails for an Accessibility Agents reviewer agent | Diff or PR link plus explanation |
+| Prompt or slash command | A prompt that guides maintainers through release-note updates | Prompt file plus example run |
+| Custom instructions | Repo-specific instructions that prevent inaccessible UI patterns | Instructions file plus scope explanation |
+| Skill or rule reference | A reusable rule pack for large-print document checks | Skill draft plus source notes |
+| Documentation update | A contribution guide that explains how to add agents safely | PR link or review-ready draft |
+| Issue triage plan | A scoped proposal for an agent the project should build next | Issue draft with mission, impact, and guardrails |
 
-## 2. Phase 1: Choose Your Agent's Mission
+### What You Need Before Starting
 
-> **See also:** [Chapter 19: Accessibility Agents](19-accessibility-agents.md) introduces the agent ecosystem and shows existing agents for inspiration.
+- [ ] You understand the fork, branch, commit, push, and PR workflow from [Chapter 18](18-fork-and-contribute.md).
+- [ ] You have GitHub Copilot or Copilot Free active from [Chapter 16](16-github-copilot.md).
+- [ ] You have explored Accessibility Agents in [Chapter 19](19-accessibility-agents.md), even if you choose a different capstone repository.
+- [ ] You know which repository you want to help and why.
+- [ ] You can explain the impact of your contribution in one or two sentences.
 
-### What makes a good agent mission
+### Time Estimate
 
-A good agent solves a specific, recurring problem. It does not try to do everything. Consider these questions:
+Most students complete a workshop-ready capstone in 60 to 90 minutes. A polished pull request can take longer, especially when the target project has tests, review requirements, or unfamiliar architecture. It is acceptable to finish the workshop with a clear draft and continue asynchronously.
 
-- **What task do you repeat?** Think about workflow steps from Day 1 and Day 2 that felt repetitive.
-- **What would a specialist know?** An agent works best when it has deep knowledge of a focused area.
-- **What gap exists?** Look at the existing agents in [Chapter 19](19-accessibility-agents.md). Is there a workflow that no agent covers?
+---
 
-### Mission categories to consider
+## 2. Choose Your Contribution Path
 
-| Category | Example missions | Existing agents in this space |
-|---|---|---|
-| Accessibility auditing | Audit color contrast in CSS variables, check form labels, validate heading hierarchy | contrast-master, forms-specialist, alt-text-headings |
-| Document accessibility | Check PDF reading order, audit Excel sheet names, validate Word heading structure | pdf-accessibility, excel-accessibility, word-accessibility |
-| GitHub workflow | Summarize notifications, track stale issues, generate release notes | daily-briefing, issue-tracker, analytics |
-| Developer tools | Validate agent files, lint markdown for accessibility, check keyboard navigation | testing-coach, link-checker, markdown-a11y-assistant |
-| Education | Explain a WCAG criterion, generate quiz questions, summarize a chapter | wcag-guide |
+Freedom is encouraged. Choose a repository where your work can be genuinely useful.
 
-### Write your mission statement
+The following table compares the recommended paths.
 
-Before writing any code, write a one-sentence mission statement:
+| Path | Best For | Good Contribution Ideas |
+| --- | --- | --- |
+| Accessibility Agents | Learners who want the most direct agent-building path | Add a focused agent, improve guardrails, update docs, refine prompts, improve skills |
+| GLOW | Learners interested in document accessibility, large print, Office files, web apps, desktop apps, or user workflows | Add a GLOW-focused agent, improve `.github` customizations, document contributor workflows, propose rule coverage |
+| Another repository | Learners with a project they already care about | Add project-specific custom instructions, an agent for maintainer workflows, accessible contribution docs, or issue templates |
 
-> "My agent helps [who] by [doing what] when [in what situation]."
+### Choosing Well
 
-Example: "My agent helps documentation authors by checking that all images in a markdown file have meaningful alt text when they open a file for review."
+Ask these questions before you choose:
 
-Write this statement in your challenge issue comment so your buddy and facilitator can give early feedback.
+- **Impact:** Who would benefit if this contribution were merged?
+- **Fit:** Does the repository already use agents, prompts, instructions, skills, or automation?
+- **Scope:** Can you make a useful change in one small pull request?
+- **Access:** Can you fork the repository or create a draft in your own fork?
+- **Safety:** Can you define guardrails that prevent the agent from overreaching?
 
 ---
 
-## 3. Phase 2: Write the Agent File
+## 3. Project Option: Accessibility Agents
 
-An agent file is a Markdown file with YAML frontmatter that defines the agent's identity, and a body that contains the agent's instructions. Agent files live in the `.github/agents/` directory (for GitHub Copilot agents) or in team-specific directories in the accessibility-agents repository.
+[Accessibility Agents](https://github.com/Community-Access/accessibility-agents) is the default capstone path because it is built around agents, prompts, instructions, skills, and accessibility workflows.
 
-### File location and naming
-
-Create your agent file at:
-
-```text
-.github/agents/your-agent-name.md
-```
+Current local inventory checked May 13, 2026:
 
-Use lowercase with hyphens. Example: `.github/agents/alt-text-validator.md`
+| Asset Type | Count |
+| --- | ---: |
+| Agent files (`*.agent.md`) | 83 |
+| Prompt files (`*.prompt.md`) | 132 |
+| Instruction files (`*.instructions.md`) | 10 |
+| Skill files (`SKILL.md`) | 207 |
+| Top-level GitHub Copilot agents in `.github/agents/` | 80 |
 
-### The agent file structure
+### Why Choose Accessibility Agents
 
-Every agent file has two parts:
+- You want to build or improve an actual agent.
+- You want clear examples to copy and adapt.
+- You want your contribution to help accessibility reviewers, developers, document remediators, GitHub maintainers, or assistive technology users.
+- You want the Challenge 16 autograder path that validates agent frontmatter, responsibilities, and guardrails.
 
-1. **YAML frontmatter** -- metadata between `---` markers at the top of the file
-2. **Instructions body** -- Markdown content that tells the agent how to behave
+### Good Accessibility Agents Contributions
 
-### Minimal agent file template
+- Add a small specialist agent for an uncovered accessibility workflow.
+- Improve an existing agent's guardrails or output format.
+- Update stale counts, platform names, or release-note guidance in documentation.
+- Add examples that show how screen reader, low vision, keyboard-only, and sighted users should use an agent.
+- Improve prompt files so they produce more structured, reviewable output.
+- Improve a skill reference with clearer severity scoring or remediation guidance.
 
-```markdown
----
-name: "Alt Text Validator"
-description: "Checks that all images in markdown files have meaningful, non-placeholder alt text."
 ---
 
-# Alt Text Validator
-
-You are an accessibility specialist focused on image alt text quality in markdown documentation.
-
-## Responsibilities
-
-- Scan markdown files for images missing alt text
-- Identify placeholder alt text like "image", "screenshot", "photo", or empty strings
-- Suggest specific, descriptive alt text based on the image context
-- Flag decorative images that should use empty alt text (`alt=""`)
-
-## Guardrails
+## 4. Project Option: GLOW
 
-- Never modify files without explicit user approval
-- Always explain why alt text needs improvement before suggesting a replacement
-- Do not generate alt text for images you cannot see -- ask the user to describe the image
-- Limit scope to the files the user asks about -- do not scan the entire repository unprompted
-```
+[GLOW](https://github.com/Community-Access/glow) stands for **Guided Layout & Output Workflow**. It is a multi-surface accessibility toolkit for auditing, fixing, converting, and generating accessible documents. It includes a web app, desktop tooling, a CLI-oriented workflow, a VS Code agent toolkit, and a Word add-in path.
 
-### YAML frontmatter fields
+GLOW focuses on document accessibility and large-print production. It enforces the American Council of the Blind Large Print Guidelines, APH submission guidance, Microsoft Accessibility Checker-style checks, and WCAG 2.2 AA concepts across formats such as Word, Excel, PowerPoint, Markdown, PDF, EPUB, HTML, and CSS.
 
-| Field | Required | Description |
-|---|---|---|
-| `name` | Yes | Display name for the agent (title case, spaces allowed) |
-| `description` | Yes | One-sentence description of what the agent does -- also drives **automatic invocation**: Copilot matches this text against your request and delegates to the agent without you selecting it manually |
+Current local inventory checked May 13, 2026:
 
-> **Write a strong description.** Vague descriptions result in missed automatic routing.
->
-> - Weak: `Helps with accessibility`
-> - Strong: `Checks markdown files for accessibility issues, fixes descriptive links and heading hierarchy, and flags alt text for human review`
->
-> The more specific the description, the more reliably Copilot invokes the right agent for the right task.
+| Asset Type | Count |
+| --- | ---: |
+| Agent files (`*.agent.md`) | 5 |
+| Prompt files (`*.prompt.md`) | 5 |
+| Instruction files (`*.instructions.md`) | 1 |
+| Skill files (`SKILL.md`) | 1 |
 
-### Writing the instructions body
+### What GLOW Does
 
-The instructions body tells the agent how to behave. Write it as if you are briefing a new team member on their first day:
+- Audits Word, Excel, PowerPoint, Markdown, PDF, EPUB, HTML, and CSS for accessibility issues.
+- Auto-fixes Word document issues where the change is deterministic, such as fonts, spacing, emphasis, headings, and margins.
+- Generates ACB-compliant Word templates.
+- Converts documents to Markdown, accessible HTML, Word, EPUB 3, PDF, and DAISY-oriented outputs through MarkItDown, Pandoc, LibreOffice, and related tooling.
+- Provides web, desktop, CLI, VS Code, and Word add-in surfaces.
+- Supports standards profiles such as ACB 2025 Baseline, APH Submission, and Combined Strict.
 
-- **Start with identity.** "You are a [role] focused on [area]."
-- **List responsibilities.** What specific tasks does this agent handle?
-- **Set guardrails.** What should the agent never do? What are its limits?
-- **Provide examples.** Show what good output looks like.
+### Why Choose GLOW
 
-> **Screen reader note:** The agent file is plain Markdown. There are no special tools needed to write it. Use any text editor.
+- You care about documents, large print, Office files, or accessible publishing.
+- You want a smaller agent surface where one contribution can make a visible difference.
+- You want to connect agents to a real product workflow: upload, audit, fix, convert, template, export, review.
+- You want to help users who may not think of themselves as developers.
 
-### Learning Cards: Writing the Agent File
+### Good GLOW Contributions
 
-<details>
-<summary>Screen reader users</summary>
+- Add a GLOW agent that helps users choose between Audit, Fix, Template, Export, and Convert workflows.
+- Improve the existing large-print agent instructions with clearer responsibilities and guardrails.
+- Add a prompt for reviewing release notes against current GLOW features.
+- Add custom instructions for web UI accessibility, plain-language findings, or large-print documentation consistency.
+- Write documentation that explains how contributors should test document accessibility changes.
+- Draft an issue for a future agent, such as a plain-language findings reviewer, batch-audit triage assistant, or Word add-in accessibility reviewer.
 
-- Create your agent file with `Ctrl+N`, then `Ctrl+S` and save to `.github/agents/your-agent-name.md` -- the Explorer navigates to the folder automatically
-- Use `Ctrl+Shift+O` to navigate between YAML frontmatter fields and Markdown headings (Responsibilities, Guardrails) in your agent file
-- The YAML frontmatter is between `---` markers at the top -- your screen reader announces these as horizontal rules
+### GLOW Safety Notes
 
-</details>
-
-<details>
-<summary>Low vision users</summary>
-
-- Agent files are standard Markdown -- open Markdown Preview (`Ctrl+Shift+V`) side by side to verify formatting as you write
-- The YAML frontmatter at the top uses `name:` and `description:` fields -- keep these on separate lines for readability at high zoom
-- Use a consistent heading hierarchy (# for title, ## for sections) so the Outline view (`Ctrl+Shift+O`) shows a clean structure
-
-</details>
-
-<details>
-<summary>Sighted users</summary>
-
-- Agent files follow a standard pattern: YAML frontmatter at the top, then identity statement, responsibilities, guardrails, and examples
-- Use the Outline view (`Ctrl+Shift+O`) to see your agent file's structure at a glance and navigate between sections
-- Copy the template from this chapter as a starting point -- replace the placeholder content with your agent's specific instructions
-
-</details>
+- GLOW handles documents that may contain personal, educational, medical, or organizational information. Do not put private user documents into public prompts or issues.
+- Auto-fix workflows must be conservative. An agent should explain proposed fixes and preserve author intent.
+- Large-print rules can affect pagination and layout. Document tradeoffs instead of pretending every fix is neutral.
+- When a rule comes from ACB, APH, Microsoft Accessibility Checker, or WCAG, cite the source or name the profile.
 
 ---
 
-## 4. Phase 3: Define Responsibilities and Guardrails
-
-Responsibilities and guardrails are the most important parts of your agent's instructions. The autograder checks that both sections exist.
+## 5. Project Option: Another Repository
 
-### Writing responsibilities
+You may choose another repository if the contribution is meaningful and reviewable. This can be your own project, a classmate's project, a community repository, or another open source project you care about.
 
-Responsibilities define what the agent does. Be specific and actionable:
+### Requirements for Another Repository
 
-**Good responsibilities (specific):**
+- The work must help the repository, not just satisfy the workshop.
+- The contribution must have a clear audience.
+- The contribution must be small enough to review.
+- The contribution must include responsibilities and guardrails when it involves an agent or automated workflow.
+- If you cannot open a pull request, write a review-ready issue or contribution plan instead.
 
-- Scan HTML files for `<img>` tags missing the `alt` attribute
-- Check that all `<button>` elements have visible text or an `aria-label`
-- Verify heading levels do not skip (e.g., `h1` to `h3` without `h2`)
+### Good Contributions in Any Repository
 
-**Weak responsibilities (vague):**
+- Add `.github/copilot-instructions.md` that teaches Copilot the project's accessibility and contribution standards.
+- Add a custom agent for triaging issues, reviewing docs, checking release notes, or auditing accessibility.
+- Add a prompt file for a repeated maintainer task.
+- Improve issue templates or PR templates so contributors provide better accessibility context.
+- Write contributor documentation that explains how to test with keyboard, screen reader, and high contrast workflows.
 
-- Help with accessibility
-- Check code
-- Find problems
+---
 
-Each responsibility should describe one discrete action the agent can take.
+## 6. Define Your Mission
 
-### Writing guardrails
+A good capstone mission solves a specific, recurring problem. It does not try to do everything.
 
-Guardrails define what the agent must not do. They prevent the agent from overstepping, giving harmful advice, or acting without permission:
+Write a one-sentence mission statement before editing files:
 
-**Good guardrails:**
+> "My contribution helps [who] by [doing what] when [in what situation]."
 
-- Never auto-fix code without asking the user first
-- Do not provide medical, legal, or financial advice when discussing accessibility compliance
-- Limit reviews to the files the user specifies -- do not scan the entire repository
-- If a finding is uncertain, say so explicitly rather than presenting it as definitive
-- Do not remove existing accessibility attributes unless they are demonstrably incorrect
+Examples:
 
-**Why guardrails matter:** An agent without guardrails will confidently do things it should not. A contrast checker that silently changes your CSS colors is dangerous. A document reviewer that deletes "unnecessary" alt text is destructive. Guardrails are how you make an agent safe.
+- "My agent helps GLOW contributors by checking whether release notes describe user-facing document accessibility changes clearly."
+- "My prompt helps Accessibility Agents maintainers by turning a release note into repo documentation updates with screen reader, low vision, and sighted guidance."
+- "My custom instructions help my project avoid inaccessible React patterns when Copilot generates forms and dialogs."
 
-### Learning Cards: Responsibilities and Guardrails
+Post this mission statement in your Challenge 16 issue comment so a buddy or facilitator can give early feedback.
 
-<details>
-<summary>Screen reader users</summary>
+---
 
-- Use `## Responsibilities` and `## Guardrails` as exact heading names -- the autograder searches for these strings
-- Each responsibility should start with a verb (Scan, Check, Verify, Flag) -- this makes them concrete and testable
-- Guardrails should start with "Never" or "Do not" to set clear boundaries your screen reader identifies as restrictions when reviewing the file
+## 7. Write or Improve the Agentic Asset
 
-</details>
+Your asset may be an agent file, prompt file, instruction file, skill, or documentation update. If you are writing an agent, use the structure below.
 
-<details>
-<summary>Low vision users</summary>
-
-- Format responsibilities as a bulleted list (starting with `-`) for easy scanning at high zoom -- one responsibility per bullet
-- Keep each guardrail to a single line so it remains visible without horizontal scrolling at your zoom level
-- Use bold text for emphasis on critical guardrails (e.g., **Never modify files without approval**) to improve visual scanning
+### Agent File Location and Naming
 
-</details>
+Follow the target repository's conventions. Common locations include:
 
-<details>
-<summary>Sighted users</summary>
+```text
+.github/agents/your-agent-name.agent.md
+agents/your-agent-name.agent.md
+community-agents/your-agent-name.agent.md
+```
 
-- The autograder checks for "Responsibilities" and "Guardrails" headings -- use exactly these words as `## ` headings
-- Aim for 4-6 responsibilities and 3-5 guardrails -- too few makes the agent vague, too many makes it rigid
-- Compare your responsibilities against the example agents in Section 9 to calibrate specificity
+Use lowercase with hyphens. Example: `.github/agents/plain-language-findings.agent.md`.
 
-</details>
+### Minimal Agent File Template
 
+```markdown
+---
+name: "Plain Language Findings Reviewer"
+description: "Reviews accessibility audit findings for plain language, actionable remediation, and user impact."
 ---
 
-## 5. Phase 4: Test Your Agent Locally
-
-> **See also:** [Chapter 18: Fork and Contribute](18-fork-and-contribute.md) covers the fork-and-PR workflow you will use to submit your agent.
-
-Before opening a pull request, test your agent to verify it works.
+# Plain Language Findings Reviewer
 
-### Testing with GitHub Copilot Chat
+You are an accessibility documentation specialist focused on making audit findings clear, actionable, and respectful.
 
-1. Open VS Code with the accessibility-agents repository.
-2. Ensure your agent file is saved in `.github/agents/`.
-3. Open GitHub Copilot Chat (`Ctrl+Alt+I`) or run **Chat: Open Chat** from the Command Palette.
-4. Invoke your agent by name: `@your-agent-name check this file for accessibility issues`
-5. Observe the response. Does the agent:
-   - Understand its mission?
-   - Follow its responsibilities?
-   - Respect its guardrails?
+## Responsibilities
 
-### Testing checklist
+- Review finding text for plain language and specific remediation steps
+- Identify vague phrases that do not explain user impact
+- Check that findings name the affected workflow or assistive technology when known
+- Suggest revised wording without changing the technical meaning
 
-- [ ] The agent responds when invoked by name
-- [ ] The agent stays within its defined responsibilities
-- [ ] The agent does not violate any guardrails
-- [ ] The agent's output is useful and specific
-- [ ] The agent handles edge cases gracefully (empty files, no issues found)
+## Guardrails
 
-### Iterating on your agent
+- Never claim a finding is fixed unless the user provides verification evidence
+- Do not remove severity or WCAG references
+- If the technical meaning is unclear, ask for clarification instead of guessing
+- Preserve project terminology unless it is inaccurate or inaccessible
+```
 
-If the agent does not behave as expected:
+### YAML Frontmatter Fields
 
-1. Read its instructions carefully. Is anything ambiguous?
-2. Add more specific instructions or examples.
-3. Test again with the same prompt.
-4. Repeat until the behavior matches your intent.
+The following table describes the common agent frontmatter fields.
 
-Most students iterate 2-3 times before they are satisfied.
+| Field | Required | Description |
+| --- | --- | --- |
+| `name` | Yes | Display name for the agent |
+| `description` | Yes | One-sentence description of what the agent does and when it should be used |
+| `tools` | Project-specific | Tool list when the target platform requires explicit tools |

+### Challenge 16 Evidence
 
-<details>
-<summary>Sighted users</summary>
+Post one of these in your Challenge 16 issue:
 
-- The autograder comment on your PR shows a table with four checks and a total score out of 60
-- Green checkmarks = passing, red X = failing -- fix failures and push to trigger a re-run
-- Include your mission statement, agent summary, and test results in the PR description for reviewers
+- A pull request link
+- A branch link with the changed file
+- A draft agent file pasted or linked
+- A contribution plan with mission, responsibilities, guardrails, and target repository
+- A review of a peer's capstone PR or a peer-simulation PR
 
-</details>
+If you use the Accessibility Agents autograder path, it checks agent file structure in `agents/` or `community-agents/`: frontmatter, responsibilities, and guardrails. If you choose GLOW or another project, your facilitator reviews the evidence against the same principles.

-## 7. Phase 6: Respond to Review
+## 10. Respond to Review
 
-After the autograder passes, a peer reviewer (your buddy or another student) and a facilitator will review your agent.
+After you submit or share your capstone, a buddy, facilitator, or maintainer may review it.
 
-### What reviewers look for
+Reviewers look for:
 
-- **Clarity:** Are the instructions easy to understand?
+- **Clarity:** Can someone understand the contribution in 10 seconds?
 - **Specificity:** Are responsibilities concrete and actionable?
-- **Safety:** Are guardrails sufficient to prevent harmful behavior?
-- **Usefulness:** Would this agent actually help someone?
-- **Scope:** Does the agent try to do too much or too little?
-
-### Responding to feedback
-
-This is the same process from [Chapter 18, Step 8](18-fork-and-contribute.md#10-step-8-respond-to-review-feedback):
+- **Safety:** Do guardrails prevent harmful or overconfident behavior?
+- **Usefulness:** Would this help a real user or maintainer?
+- **Fit:** Does it follow the target repository's conventions?
 
-1. Read each review comment.
-2. Make changes locally.
-3. Commit and push. The PR updates automatically.
-4. Reply to each comment explaining your changes.
-
-### When your PR is merged
-
-Congratulations. Your agent is now part of the accessibility-agents ecosystem. It is available to anyone who uses the repository. This is a real open source contribution, and it demonstrates:
-
-- You can navigate the fork workflow end to end
-- You can write clear, structured technical documentation
-- You understand accessibility concepts well enough to teach an AI agent about them
-- You can respond constructively to code review
+Respond to review one comment at a time. If a reviewer asks for a change, make the edit, commit, push, and reply with what changed.

-## 8. Capstone Rubric
-
-The capstone is worth 60 autograded points plus peer review. Here is the complete rubric:
-
-### Autograded (60 points)
-
-| Criterion | Points | What the autograder checks |
-|---|---|---|
-| Agent file exists | 10 | A Markdown file exists in the agents directory |
-| Valid YAML frontmatter | 15 | File has `---` delimiters, `name` field, `description` field |
-| Responsibilities defined | 15 | A section with the heading "Responsibilities" exists and contains content |
-| Guardrails defined | 20 | A section with the heading "Guardrails" exists and contains content |
-
-### Peer review (qualitative)
-
-| Criterion | What reviewers assess |
-|---|---|
-| Mission clarity | Can a reader understand what the agent does in 10 seconds? |
-| Instruction quality | Are instructions specific enough that the agent behaves consistently? |
-| Guardrail coverage | Do the guardrails prevent the most obvious failure modes? |
-| Contribution standards | Does the PR follow the project's conventions and include a good description? |
+## 11. Capstone Rubric
 
-### What "meets expectations" looks like
+The capstone is assessed as a real contribution, not just as a file format exercise.
 
-A capstone that meets expectations has:
+### Core Criteria
 
-- A focused mission (not "help with accessibility" -- something specific)
-- At least 3 concrete responsibilities
-- At least 3 meaningful guardrails
-- A PR description that explains the agent's purpose
-- All autograder checks passing
+The following table lists the capstone evaluation criteria.
 
-### What "exceeds expectations" looks like
+| Criterion | Meets Expectations |
+| --- | --- |
+| Repository choice | The learner can explain why the chosen repository benefits from the contribution |
+| Mission clarity | The contribution has a focused mission statement |
+| Responsibilities | The agentic asset names concrete actions it should perform |
+| Guardrails | The contribution includes boundaries, limitations, or safety notes |
+| Accessibility impact | The work accounts for screen reader, low vision, keyboard-only, cognitive, or document accessibility needs when relevant |
+| Evidence | The learner provides a PR, draft, branch, issue, or contribution plan |
+| Review readiness | The contribution is small enough for someone else to review |
 
-A capstone that exceeds expectations also has:
+### What Exceeds Expectations Looks Like
 
-- Examples of expected input and output in the agent instructions
-- A section describing the agent's limitations
-- Evidence of testing (screenshots or transcripts in the PR description)
-- Thoughtful responses to review feedback
+- The contribution includes examples of expected input and output.
+- The PR description explains tradeoffs and limitations.
+- The learner tests with Copilot Chat or the VS Code Agents window and documents the result.
+- The learner responds thoughtfully to review feedback.
+- The contribution improves existing documentation, counts, or setup instructions alongside the agentic asset.

-## 9. Example Agents for Inspiration
-
-These examples show the range of valid agent designs. Your agent does not need to be this long, but it should be this clear.
-
-### Example 1: Heading Hierarchy Checker
-
-**Mission:** Validates that HTML and Markdown documents follow a correct heading hierarchy (no skipped levels).
-
-**Responsibilities:**
-
-- Scan files for heading elements (`h1` through `h6` in HTML, `#` through `######` in Markdown)
-- Report any instance where a heading level is skipped (e.g., `h2` followed by `h4`)
-- Suggest the correct heading level for each violation
-- Check that there is exactly one `h1` per page
-
-**Guardrails:**
-
-- Do not modify files -- only report findings
-- Do not change heading text, only heading levels
-- If a heading structure decision is ambiguous, present both options and let the user decide
-
-### Example 2: PR Description Quality Gate
-
-**Mission:** Reviews pull request descriptions to ensure they contain enough context for reviewers.
-
-**Responsibilities:**
-
-- Check that the PR description is at least 50 characters
-- Verify the description references an issue with `Closes #XX` or `Fixes #XX`
-- Check for a summary of changes made
-- Verify the description explains why the change was made, not just what was changed
-
-**Guardrails:**
-
-- Never approve or block a PR based solely on description quality
-- Do not rewrite the description for the author -- suggest improvements
-- Respect that different projects have different template requirements
-
-### Example 3: Keyboard Navigation Auditor
-
-**Mission:** Checks web components for keyboard accessibility compliance.
-
-**Responsibilities:**
-
-- Verify all interactive elements are reachable via Tab key
-- Check that custom components have appropriate `tabindex` values
-- Validate that focus order follows visual layout
-- Detect keyboard traps (elements that receive focus but cannot release it via keyboard)
-
-**Guardrails:**
-
-- Do not modify component code without user approval
-- Flag potential issues with confidence levels (certain, likely, possible)
-- Acknowledge that some keyboard patterns depend on runtime behavior that cannot be verified from source code alone

+## 12. If You Get Stuck
 
-## 10. If You Get Stuck
+The following table lists common capstone blockers and recovery steps.
 
-| Problem | What to do |
-|---|---|
-| Cannot think of an agent idea | Look at the existing agents in [Chapter 19](19-accessibility-agents.md). What adjacent task is not covered? |
-| YAML frontmatter is invalid | Check that you have `---` on its own line at the start and end. Verify `name` and `description` are quoted strings. |
-| Autograder says "Responsibilities section not found" | Make sure you have a Markdown heading that says exactly `## Responsibilities`. |
-| Autograder says "Guardrails section not found" | Make sure you have a Markdown heading that says exactly `## Guardrails`. |
-| Agent does not respond in Copilot Chat | Verify the file is saved in `.github/agents/` and has a `.md` extension. Restart Copilot Chat. |
-| Agent ignores its guardrails | Add more explicit instructions. Instead of "be careful," say "Never do X under any circumstances." |
-| PR fails to open across forks | Verify you are comparing your fork's branch against the upstream's `main`. See [Chapter 18, Step 7](18-fork-and-contribute.md#9-step-7-open-a-pull-request). |
-| Reviewer feedback feels overwhelming | Address one comment at a time. Start with the smallest change. Reply to each comment individually. |
-| I finished but I am not sure I did it right | Compare your work against the [Challenge 16 reference solution](solutions/solution-16-capstone.md). If your agent file has valid frontmatter, responsibilities, and guardrails, you succeeded. |
+| Problem | What To Do |
+| --- | --- |
+| I cannot choose a repository | Choose Accessibility Agents if you want the clearest agent path, or GLOW if you want document accessibility and large-print impact |
+| I cannot think of an idea | Find one repeated maintainer task and write an agent or prompt for that task |
+| I do not have permission to open a PR | Create a draft in your fork or write a contribution issue with mission, responsibilities, and guardrails |
+| The repository has no agents yet | Add repo-level custom instructions or propose the first agent in a draft issue |
+| My agent does too much | Split the mission until it fits one sentence |
+| Copilot ignores the guardrails | Make the guardrails more explicit and test with the same prompt again |
+| The external project has different conventions | Follow that project's README and CONTRIBUTING file first, then explain any uncertainty in your PR |
+| I finished but I am not sure I did it right | Compare your work against the [Challenge 16 reference solution](solutions/solution-16-capstone.md), then ask for review |

-The capstone is where you design a small agent of your own and prepare it as a contribution. The important part is not a flashy idea. The important part is a clear purpose, useful responsibilities, and boundaries that keep the agent safe and honest.
+The capstone is where you choose a real repository and prepare an impactful agentic contribution. Accessibility Agents is the default path, GLOW is a strong document-accessibility path, and another project is valid when your contribution would genuinely help that repository. The important part is not a flashy idea. The important part is a clear purpose, useful responsibilities, and boundaries that keep the work safe and honest.
 
 **What to do:**
 
-1. Fork the [Community Access Accessibility Agents repository](https://github.com/Community-Access/accessibility-agents)
-2. Clone your fork and create a branch named `agent/YOUR-USERNAME`
-3. Write an `.agent.md` file with YAML frontmatter, responsibilities, and guardrails
-4. Push and open a cross-fork PR to the original repository
-5. Review a classmate's capstone PR when one is available
+1. Choose your target repository: [Accessibility Agents](https://github.com/Community-Access/accessibility-agents), [GLOW](https://github.com/Community-Access/glow), or another project you can explain.
+2. Write a one-sentence mission statement for the contribution.
+3. Create or improve an agent, prompt, instruction file, skill, workflow, or documentation page.
+4. Include responsibilities and guardrails when the contribution involves an agent or automation.
+5. Push and open a pull request, or prepare a review-ready branch, issue, or contribution plan if you do not have access.
+6. Review a classmate's capstone PR when one is available.
 
 Use the [agent file template](../learning-room/docs/samples/agent-file-template.md) and [fork workflow checklist](../learning-room/docs/samples/fork-workflow-checklist.md) for structure.
 
-**Evidence to post:** Link to your capstone PR or summarize the agent file you created. The autograder verifies required agent structure when the file is represented in the Learning Room.
+**Evidence to post:** Link to your capstone PR, branch, draft issue, or contribution plan. Include the repository you chose, the mission statement, what you changed or proposed, how you tested it, and the responsibilities and guardrails that make it safe.

 ### Organization (Org)
 
 An organization is a group account on GitHub that multiple people can belong to. Open source projects typically live inside an organization rather than under a personal account. For example: `https://github.com/microsoft/vscode` - here `microsoft` is the organization and `vscode` is the repository.
 
-
 ### Fork
 
 A fork is a personal copy of someone else's repository, living in your own GitHub account. When you fork a repo, you get all its files and history. Changes you make to your fork do not automatically affect the original. To propose your changes to the original project, you submit a pull request.
 
 **Why fork?** You do not have write access to most open source repos. Forking lets you work freely and then propose changes.

 A diff (short for difference) shows what changed between two versions of a file. Lines that were **added** are shown in green (with a `+` prefix). Lines that were **removed** are shown in red (with a `-` prefix). Lines that are unchanged are shown in grey for context.

 ### Project (GitHub Projects)
 
 A GitHub Project is a flexible board for tracking work. It can show issues and PRs in table view, board view (kanban), or roadmap view. Projects are especially useful for hackathon-style coordination.
 
-
 ## Part 3: People and Roles
 
 ### Maintainer
 
 A maintainer is someone with write or admin access to a repository. Maintainers review PRs, triage issues, manage releases, and make decisions about the project's direction. Most open source projects have between one and five core maintainers.
 
-
 ### Contributor
 
 Anyone who contributes to an open source project is a contributor. Contributing includes code, documentation, design, testing, translation, issue triage, and community support. You do not need commit access to contribute.
 
-
 ### Triage
 
 Triaging issues means reviewing new issues to categorize them, add labels, assign them, close duplicates, and communicate with the reporter. Triage is an important contribution that doesn't require coding skills.
 
-
 ### Collaborator
 
 A collaborator is someone who has been explicitly granted write access to a repository. Collaborators can commit directly to the repo without forking (though good practice is still to use branches and PRs).

 ### SHA / Hash
 
 Every commit, file, and tree in Git is identified by a SHA hash - a 40-character string of letters and numbers (e.g., `a1b2c3d4e5f6...`). You will see shortened versions like `a1b2c3d` in the GitHub UI. These are unique fingerprints.
 
-
 ### Tag / Release
 
 A tag marks a specific commit as significant - usually a version release like `v1.0.0`. Tags are permanent references (unlike branches, which move with each new commit). GitHub Releases are built on top of tags and can include release notes and downloadable files.
 
-
 ### Actions / Workflow / CI/CD
 
 GitHub Actions is an automation platform built into GitHub. Workflows are automated scripts (written in YAML) that run in response to events - like a PR being opened or code being pushed. CI/CD stands for Continuous Integration / Continuous Deployment.
 
 In practice: when you open a PR, you will often see automated checks run (tests, linting, accessibility checks). These are GitHub Actions. See [GitHub Actions & Workflows](appendix-q-actions-workflows.md) for a full explanation.

-
 ### Webhook
 
 A webhook is an automated notification that GitHub sends to another service when something happens (a push, a PR opened, etc.). Webhooks power integrations with tools like Slack, project management systems, and CI services. As a contributor, you typically don't configure webhooks - they are set up by maintainers.
 
-
 ### GitHub Discussions
 
 Discussions are a threaded forum built into GitHub, separate from Issues. They are used for open-ended conversation, Q&A, and community announcements. Not all projects use Discussions - some prefer issues or external forums.
 
-
 ### Profile
 
 Your GitHub profile is your public identity. It shows your name, bio, location, repositories, contribution activity (the green squares), and pinned projects. Your profile URL is `https://github.com/your-username`.
 
-
 ### GitHub Copilot
 
 GitHub Copilot is an AI-powered coding assistant. It suggests code, documentation, and commit messages. In this workshop, we use Copilot to help write issue descriptions, PR descriptions, documentation, and code. See [GitHub Copilot](16-github-copilot.md) for the full walkthrough.

+## Architecture, Skills, Hooks, and Advanced Patterns for AI Agents
+
+> This appendix covers how to build sophisticated agent workflows using subagent delegation, lifecycle hooks, reusable skills, and browser automation tools. These patterns scale beyond single-agent use to orchestrate complex accessibility audits and remediation workflows.
+
+## Table of Contents
+
+1. [Architecture: Agents and Subagents](#1-architecture-agents-and-subagents)
+2. [Skills: Reusable Multi-Step Workflows](#2-skills-reusable-multi-step-workflows)
+3. [Hooks: Lifecycle Automation](#3-hooks-lifecycle-automation)

+
+## 1. Architecture: Agents and Subagents
+
+### What Are Subagents?
+
+An **agent** is a standalone AI system (like `@aria-specialist`) that understands one domain (ARIA patterns). A **subagent** is an agent invoked by another agent to delegate work.
+
+**Example workflow:**
+```
+User: @web-accessibility-wizard [audit this page]
+  ↓ (orchestrates multiple specialists)
+  ├─→ @aria-specialist (check ARIA roles)
+  ├─→ @contrast-master (check colors)
+  ├─→ @keyboard-navigator (check tab order)
+  ├─→ @alt-text-headings (check images and headings)
+  └─→ @tables-specialist (check table markup)
+  ↓ (aggregates results)
+Output: [consolidated audit report]
+```
+
+### How to Use Subagents
+
+In your agent's instructions or a custom prompt, invoke subagents with the `runSubagent()` function:
+
+```markdown
+<!-- In your .agent.md or .prompt.md file -->
+
+## Use Subagents for Deep Audits
+
+When you need to audit multiple aspects of a page, use subagents:
+
+```javascript
+// Pseudo-code - how agents invoke subagents
+const results = await runSubagent({
+  agentName: '@aria-specialist',
+  prompt: 'Check this component for ARIA compliance: <component HTML>',
+  description: 'ARIA pattern review'
+});
+
+const contrastResults = await runSubagent({
+  agentName: '@contrast-master',
+  prompt: 'Audit these colors: <CSS rules>',
+  description: 'Color contrast verification'
+});
+```
+
+### When to Use Subagents
+
+| Scenario | Primary Agent | Subagents | Benefit |
+|----------|---------------|-----------|---------| 
+| **Full page audit** | `@web-accessibility-wizard` | All specialists | Parallel scanning, consolidated report |
+| **Code review** | `@web-issue-fixer` | `@aria-specialist`, `@contrast-master` | Verify fixes across multiple domains |
+| **Document audit** | `@document-accessibility-wizard` | Platform-specific agents | Single entry point for Word/PDF/Excel |
+| **Markdown audit** | `@markdown-a11y-assistant` | `@link-checker` | Cross-check link text and heading hierarchy |
+
+### Subagent Architecture Principles
+
+1. **Delegation over monoliths:** One agent calls specialists; specialists don't call other specialists (avoid infinite loops)
+2. **Error recovery:** If a subagent fails, the parent agent logs it and continues with other subagents
+3. **Context preservation:** Parent passes full context (HTML, CSS, document) to subagents
+4. **Result aggregation:** Parent collects results and produces a single consolidated report
+
+## 2. Skills: Reusable Multi-Step Workflows
+
+### What Are Skills?
+
+A **skill** is a reusable, multi-step workflow bundled with reference files, templates, and automation scripts. Skills are invoked by agents or directly by users via slash commands.
+
+**Example:** The `web-scanning` skill contains:
+- Step-by-step crawling logic
+- URL inventory templates
+- Browser automation code
+- Reference documentation
+
+**Example:** The `report-generation` skill contains:
+- Severity scoring algorithms
+- Scorecard templates
+- CSV export logic
+- WCAG mapping reference data
+
+### The 25+ Core Skills
+
+Accessibility Agents includes a library of reusable skills organized by capability:
+
+| Skill Category | Skills | Purpose |
+|----------------|--------|---------|
+| **Web Scanning** | `web-scanning`, `web-severity-scoring` | Page inventory, audit scope, severity calculation |
+| **Web Remediation** | `web-issue-fixer`, `web-csv-reporter` | Apply fixes, export findings to CSV |
+| **Document Scanning** | `document-scanning`, `document-accessibility-rules` | Audit Word/Excel/PDF/EPUB; map to WCAG |
+| **Document Remediation** | `document-remediation`, `document-csv-reporter` | Fix documents; generate compliance reports |
+| **Markdown** | `markdown-accessibility`, `markdown-fixer`, `markdown-csv-reporter` | Audit .md files; fix links, headings, emoji |
+| **CI/CD Integration** | `lighthouse-scanner`, `github-accessibility-scanner` | Parse CI reports; track regressions |
+| **Framework Specifics** | `framework-accessibility`, `react-patterns`, `vue-patterns` | Framework-specific accessibility patterns |
+| **Python Dev Tools** | `python-fact-grounded-coding`, `pylance-refactoring` | Python code analysis, accessibility linting |
+| **Testing** | `testing-coach`, `accessibility-testing-setup` | Screen reader testing, test automation, CI/CD setup |
+| **Compliance** | `wcag-guide`, `accessibility-rules-reference`, `help-url-reference` | WCAG 2.2 AA reference, remediation links |
+
+### How to Use a Skill
+
+**From Copilot Chat:**
+```
+/web-scanning [URL]
+/report-generation [findings JSON]
+/python-fact-grounded-coding my_script.py
+```
+
+**From a Custom Agent:**
+```markdown
+## Invoke Skills
+
+When you need to audit a webpage, use the web-scanning skill:
+
+"Scan the following URL for accessibility issues and generate a severity score."
+
+- URL: https://example.com
+- Severity model: WCAG 2.2 AA
+- Output: JSON report
+```
+
+### Skill Authoring Pattern
+
+If you are writing a custom skill, follow this structure:
+
+**File: `.github/skills/my-skill-name/SKILL.md`**
+
+```markdown
+# My Skill Name
+
+## Purpose
+What problem does this skill solve?
+
+## Inputs
+- URL or file path
+- Configuration (optional)
+
+## Workflow
+1. Parse input
+2. Execute steps
+3. Collect results
+4. Format output
+
+## Output
+- Report format (JSON, Markdown, CSV)
+- Example output
+
+## References
+- Links to related agents
+- Links to external docs
+```
+
+**Supporting files:**
+- `templates/` - Templates for input/output
+- `scripts/` - Automation scripts (shell, Python)
+- `reference/` - Reference data (lookup tables, compliance mappings)
+
+### Skill Reuse Across Agents
+
+Skills are designed to be called by multiple agents. For example:
+
+- `@web-accessibility-wizard` uses `web-scanning` + `web-severity-scoring`
+- `@web-issue-fixer` uses `web-scanning` + `web-issue-fixer`
+- `@link-checker` uses `web-scanning` + a link-validation subset
+
+This prevents code duplication and ensures consistent behavior across agents.
+
+## 3. Hooks: Lifecycle Automation
+
+### What Are Hooks?
+
+A **hook** is a JSON configuration that triggers agent actions automatically at specific lifecycle events. Hooks enforce accessibility standards without requiring the user to remember to ask for an audit.
+
+**Lifecycle events:**
+- On file edit (before save)
+- On file save (after save)
+- On commit (before push)
+- On PR creation (before merge)
+- On scheduled interval (nightly, weekly)
+
+### Hook Configuration Format
+
+**File: `.github/hooks/accessibility.hooks.json`**
+
+```json
+{
+  "hooks": [
+    {
+      "name": "proactive-detection",
+      "event": "on-file-edit",
+      "pattern": "**/*.{html,jsx,tsx,vue}",
+      "agent": "@aria-specialist",
+      "condition": "file.includes('aria')",
+      "action": "highlight-violations",
+      "severity": "warning"
+    },
+    {
+      "name": "edit-gate",
+      "event": "on-file-save",
+      "pattern": "src/**/*.tsx",

+    },
+    {
+      "name": "commit-check",
+      "event": "on-commit",
+      "pattern": "**/*",
+      "agent": "@accessibility-lead",

+      "agent": "@markdown-a11y-assistant",
+      "action": "create-issue",
+      "labels": ["accessibility", "auto-audit"]
+    }
+  ]
+}
+```
+
+### Hook Properties
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `name` | string | Unique hook identifier |
+| `event` | enum | `on-file-edit`, `on-file-save`, `on-commit`, `on-pr-create`, `on-schedule` |
+| `pattern` | glob | File path pattern (e.g., `**/*.tsx`) |

+
+### Hook Examples
+
+**Example 1: Proactive ARIA Detection**
+
+```json
+{
+  "name": "aria-proactive-check",
+  "event": "on-file-edit",
+  "pattern": "src/**/*.jsx",
+  "agent": "@aria-specialist",
+  "condition": "true",
+  "action": "highlight-violations",
+  "severity": "warning"
+}
+```
+
+**Behavior:** As you type in a `.jsx` file, violations are highlighted in real time.
+
+**Example 2: Block Non-Accessible Commits**
+
+```json
+{
+  "name": "accessibility-commit-gate",
+  "event": "on-commit",
+  "pattern": "**/*",
+  "agent": "@web-accessibility-wizard",
+  "condition": "severity >= 'error'",
+  "action": "block-save",
+  "message": "Critical accessibility issues detected. Run @web-issue-fixer to resolve."
+}
+```
+
+**Behavior:** Commits are blocked if critical accessibility violations are found.
+
+**Example 3: Nightly Document Audits**
+
+```json
+{
+  "name": "nightly-markdown-audit",
+  "event": "on-schedule",
+  "schedule": "0 2 * * *",
+  "pattern": "docs/**/*.md",
+  "agent": "@markdown-a11y-assistant",
+  "action": "create-issue",
+  "labels": ["a11y", "auto-audit", "documentation"]
+}
+```
+
+**Behavior:** Every night at 2 AM, markdown files are audited and issues are created automatically.
+
+### Enabling Hooks by Platform
+
+**GitHub Copilot (VS Code):**
+- Place `accessibility.hooks.json` in `.github/hooks/`
+- Hooks are read on workspace open
+- View hook status: Settings Gear → Accessibility Hooks
+
+**Claude Code:**
+- Configure in `.claude-code.toml`:
+  ```toml
+  [hooks]
+  enabled = true
+  config_file = ".github/hooks/accessibility.hooks.json"
+  ```
+
+**Claude Desktop (MCP):**
+- Configure in `.mcp.json`:
+  ```json
+  {
+    "accessibility-agents": {
+      "hooks": {
+        "enabled": true,
+        "config": ".github/hooks/accessibility.hooks.json"
+      }
+    }
+  }
+  ```
+
+## 4. Browser Tools for Behavioral Scanning
+
+### Available Browser Tools
+
+Accessibility Agents includes browser automation tools for interactive scanning:
+
+| Tool | What It Does | When to Use |
+|------|--------------|------------|
+| `scan-page` | Single page audit (static + dynamic) | Quick single-page check |
+| `scan-pages` | Crawl URL and audit all pages | Site audit, scope definition |
+| `scan-dom` | Live DOM inspection | Debug dynamic content |
+| `scan-with-lighthouse` | Lighthouse accessibility audit | Performance + a11y scoring |
+| `scan-with-playwright` | Playwright automated testing | Interactive flows, form testing |
+| `get-page-outline` | Extract page structure | Understand heading hierarchy |
+| `detect-color-contrast` | CSS color analysis | Find contrast violations |
+| `find-aria-roles` | ARIA role inventory | Understand ARIA implementation |
+
+### Using Browser Tools in Agents
+
+**Pattern 1: Direct Tool Invocation**
+
+```markdown
+## Audit Page Accessibility
+
+When the user provides a URL, use the scan-page tool:
+
+1. Call `scan-page(url)` to get accessibility findings
+2. Filter findings by severity
+3. Group by category (ARIA, contrast, keyboard, etc.)
+4. Present results in a prioritized table
+
+Example:
+**User:** Audit https://example.com for accessibility issues
+**Agent:** 
+- Calls `scan-page("https://example.com")`
+- Receives findings JSON
+- Groups by category and severity
+- Reports top 10 issues
+```
+
+**Pattern 2: Conditional Scanning**
+
+```markdown
+## Smart Audit Based on Page Content
+
+1. Call `get-page-outline(url)` to understand structure
+2. If heading hierarchy is broken:
+   - Recommend structure fixes (use @alt-text-headings)
+3. If many interactive components detected:
+   - Recommend ARIA review (use @aria-specialist)
+4. If dynamic content detected:
+   - Recommend behavioral testing (use @testing-coach)
+```
+
+**Pattern 3: Playwright for Complex Workflows**
+
+```javascript
+// Pseudo-code: Test a multi-step form
+const browser = await playwright.launch();
+const page = await browser.newPage();
+
+await page.goto('https://example.com/form');
+await page.fill('#name', 'Jane Doe');
+await page.fill('#email', 'jane@example.com');
+await page.click('button:has-text("Submit")');
+
+// Check for error messages (accessibility of feedback)
+const errorMessage = await page.locator('[role="alert"]');
+const text = await errorMessage.innerText();
+
+console.log(`Error announced: ${text}`);
+
+await browser.close();
+```
+
+### Browser Tool Limitations and Workarounds
+
+| Limitation | Workaround |
+|------------|-----------|
+| Cannot test with actual screen readers | Use @testing-coach guidance instead; CLI offers NVDA integration |
+| JavaScript-heavy pages may be incomplete | Increase wait time: `waitForNavigation()` |
+| Some dynamic content misses ARIA updates | Use Playwright to trigger updates and re-scan |
+| Cannot test keyboard without manual intervention | Use @keyboard-navigator for structural analysis |
+
+## 5. Orchestration: Delegation Patterns
+
+### Pattern 1: Parallel Scanning (Web Accessibility Wizard)
+
+**Goal:** Audit multiple aspects of a page simultaneously for speed.
+
+```
+User request: Audit this page
+  │
+  ├─ @aria-specialist (scan ARIA)
+  ├─ @contrast-master (scan colors)
+  ├─ @keyboard-navigator (scan keyboard flow)
+  ├─ @alt-text-headings (scan images/headings)
+  └─ @tables-specialist (scan tables)
+  │
+  ↓ (all run in parallel, results aggregated)
+  │
+  Consolidated Report:
+  - Severity: 12 errors, 8 warnings
+  - Priority issues (blocking top 5)
+  - Detailed findings per agent
+```
+
+**Agent code pattern:**
+
+```markdown
+## Parallel Audit
+
+Invoke all specialist agents in parallel:
+
+1. Gather all findings simultaneously (not sequentially)
+2. Deduplicate issues across agents
+3. Sort by severity
+4. Present top 10 blocking issues first
+5. Link to detailed fix guidance per agent
+```
+
+### Pattern 2: Cascading Fixes (Web Issue Fixer)
+
+**Goal:** Fix issues in order of severity and dependency.
+
+```
+Findings identified:
+  1. Missing alt text (3 images)
+  2. Poor color contrast (5 elements)
+  3. Missing form labels (2 inputs)
+  4. ARIA misuse (1 element)
+
+Remediation order:
+  1. Fix ARIA misuse first (foundational)
+  2. Add form labels (unblocks testing)
+  3. Add alt text (content layer)
+  4. Fix contrast (visual layer)
+
+Output: Numbered PR suggestions, 1 fix per commit message
+```
+
+### Pattern 3: Skill-First Workflows (Testing Coach)
+
+**Goal:** Guide users through testing workflows without assuming prior knowledge.
+
+```
+User: How do I test keyboard navigation?
+
+Agent (@testing-coach) response:
+
+1. Ask clarifying questions:
+   - Have you used NVDA before?
+   - What platform (Windows/Mac/Linux)?
+   - What component type (form/menu/modal)?
+
+2. Recommend testing path:
+   - Step 1: Learn Tab order basics (video link)
+   - Step 2: Test with keyboard-only (no mouse)
+   - Step 3: Verify focus indicators visible
+   - Step 4: Check against WCAG 2.5.4
+
+3. Provide interactive test:
+   - Code snippet to inject focus indicators
+   - Keyboard test checklist
+   - Screenshot comparison guide
+```
+
+### Pattern 4: Report Aggregation (Cross-Page Analyzer)
+
+**Goal:** Consolidate findings across multiple pages into systemic issues.
+
+```
+Input: 50 pages audited
+
+Output:
+- Systemic issues (found on 10+ pages):
+  - Color contrast: 45 instances across 18 pages
+  - Missing alt text: 120 instances across 32 pages
+  
+- Page-specific issues (found on 1-2 pages):
+  - Modal focus trap broken (page 15)
+  - ARIA combobox pattern error (page 3)
+
+- Severity scorecard:
+  - Overall score: 62/100 (D grade)
+  - Top 3 fixes: address these to reach 75/100
+  - Estimated effort: 8-12 hours
+```
+
+## 6. Advanced Techniques
+
+### Technique 1: Custom Skills for Your Organization
+
+If your organization has repeated accessibility patterns, bundle them as a custom skill:
+
+```markdown
+# .github/skills/our-pattern-library/SKILL.md
+
+## Our Accessibility Pattern Library
+
+### Purpose
+Codify internal accessibility standards and patterns used across all projects.
+
+### Patterns Included
+1. Form validation messaging
+2. Accessible modal templates
+3. Color palette compliance
+4. Data table best practices
+
+### Inputs
+- HTML snippet or component name
+- Pattern ID (e.g., "form-validation-v2")
+
+### Output
+- Remediation code
+- Compliance checklist
+- Testing steps
+
+### Usage
+@custom-agent check-pattern "form-validation-v2" [HTML]
+```
+
+### Technique 2: Continuous Evaluation Hooks
+
+Set up automated evaluation to measure improvement over time:
+
+```json
+{
+  "name": "continuous-accessibility-eval",
+  "event": "on-schedule",
+  "schedule": "0 0 * * 0",
+  "pattern": "src/**/*",
+  "agent": "@accessibility-lead",
+  "action": "create-eval-report",
+  "track": {
+    "metrics": ["page-score", "error-count", "warning-count"],
+    "baseline": "2026-01-01",
+    "frequency": "weekly"
+  }
+}
+```
+
+### Technique 3: Platform-Specific Skill Variants
+
+Create platform-specific implementations of the same skill:
+
+```
+.github/skills/form-accessibility/
+  ├── SKILL.md (base description)
+  ├── implementations/
+  │   ├── react/form-pattern.tsx
+  │   ├── vue/form-pattern.vue
+  │   ├── svelte/form-pattern.svelte
+  │   └── vanilla/form-pattern.js
+```
+
+**Agents select the implementation matching the detected framework.**
+
+### Technique 4: Result Caching for Performance
+
+For repeated audits (e.g., nightly checks), cache results to speed up analysis:
+
+```json
+{
+  "name": "smart-audit-with-cache",
+  "event": "on-schedule",
+  "schedule": "0 2 * * *",
+  "pattern": "docs/**/*.md",
+  "cache": {
+    "enabled": true,
+    "ttl": 86400,
+    "key": "filepath + git-commit-hash"
+  },
+  "action": "compare-to-previous"
+}
+```
+
+**Behavior:** Only re-audited files that changed since the last run; unchanged files use cached results.

+
+## 4. Developer Tools Team (8 Agents)
+
+### Developer Tools Agents Overview
+
+The Developer Tools Team supports accessible application development across Python, wxPython, CI/CD pipelines, and desktop environments.
+
+| Agent | Purpose | When to Use |
+|-------|---------|-----------|
+| `@python-specialist` | Python accessibility patterns and best practices | Building accessible Python CLI tools and libraries |
+| `@wxpython-specialist` | wxPython GUI accessibility (Windows, Mac, Linux) | Building desktop applications with wxPython |
+| `@ci-accessibility` | CI/CD pipeline accessibility integration | Adding accessibility checks to GitHub Actions, Jenkins, etc. |
+| `@playwright-scanner` | Automated browser testing with Playwright | Testing interactive web pages for accessibility |
+| `@playwright-verifier` | Verify Playwright test coverage | Ensuring accessibility tests have complete coverage |
+| `@screen-reader-lab` | Screen reader testing setup and guidance | Manual NVDA, JAWS, VoiceOver testing |
+| `@nvda-addon-developer` | Develop NVDA accessibility add-ons | Building extensions for NVDA screen reader |
+| `@desktop-a11y-specialist` | Desktop accessibility (Windows, Mac, Linux UIA) | Native desktop app accessibility |
+
+## 5. Python & wxPython Accessibility
+
+### Python Accessibility Best Practices
+
+**Common patterns in accessible Python code:**
+
+| Pattern | Example | Why It Matters |
+|---------|---------|---------------| 
+| **Clear function names** | `check_alt_text()` not `chk_at()` | Screen readers announce the full name |
+| **Docstrings for all functions** | Include purpose, args, returns | Documentation tools (and assistants) understand intent |
+| **Type hints** | `def scan(url: str) -> Dict[str, Any]:` | Type checkers catch errors early |
+| **Logging, not silent failures** | `logger.error("Alt text missing")` | Debuggable by all users |
+| **Accessible CLI help** | `--help` output clearly structured | Keyboard and screen reader users can find options |
+
+**Using `@python-specialist`:**
+
+```
+User: @python-specialist review my accessibility scanning script
+
+Agent response:
+1. Analyzes code for:
+   - Clear naming conventions
+   - Comprehensive docstrings
+   - Type hints present
+   - Error handling clear
+   - Logging patterns
+2. Suggests improvements:
+   - Add docstrings to 3 functions
+   - Type hint 5 parameters
+   - Restructure exception handling
+   - Add logging at key checkpoints
+```
+
+### wxPython GUI Accessibility
+
+wxPython is a cross-platform GUI toolkit. Accessibility requires following platform conventions.
+
+**wxPython accessibility checklist:**
+
+| Element | Requirement | Implementation |
+|---------|-------------|----------------|
+| **Windows** | Use Microsoft UI Automation (UIA) | wxPython provides UIA support via wx.adv |
+| **Labels** | All controls labeled | Use `SetLabel()` or associate with `wx.StaticText` |
+| **Tab order** | Logical keyboard navigation | Use `wx.Window.MoveBeforeInTabOrder()` |
+| **Focus indicators** | Visible focus outline | Platform default usually sufficient |
+| **Keyboard shortcuts** | Alt+key for menus | Use `&` in menu labels: `"&File"` |
+| **Dialogs** | Modal dialogs announce role | `wx.Dialog` automatically marks as modal |
+
+**Using `@wxpython-specialist`:**
+
+```
+User: @wxpython-specialist audit my-app.py
+
+Agent response:
+1. Analyzes wxPython code:
+   - Control labeling
+   - Tab order
+   - Keyboard support
+   - Dialog structure
+2. Reports:
+   - 2 controls missing labels
+   - Tab order needs sorting (currently 5, 3, 1, 2, 4)
+   - Missing keyboard shortcuts on File menu
+3. Provides template code for fixes
+```
+
+**wxPython Accessible Control Example:**
+
+```python
+import wx
+
+class AccessibleFrame(wx.Frame):
+    def __init__(self):
+        super().__init__(None, title="Accessible App")
+        
+        panel = wx.Panel(self)
+        
+        # Labeled text input
+        label = wx.StaticText(panel, label="Name:")
+        text_ctrl = wx.TextCtrl(panel)
+        text_ctrl.SetName("Name input field")
+        
+        # Accessible button with shortcut
+        button = wx.Button(panel, label="&Submit")  # Alt+S shortcut
+        button.SetName("Submit button")
+        
+        # Sizer for layout
+        sizer = wx.BoxSizer(wx.VERTICAL)
+        sizer.Add(label)
+        sizer.Add(text_ctrl)
+        sizer.Add(button)
+        panel.SetSizer(sizer)
+```
+
+## 6. Desktop & NVDA Development
+
+### Desktop Application Accessibility
+
+Desktop applications must follow OS conventions:
+
+**Windows (Microsoft UI Automation):**
+- All controls must expose their role (button, text, etc.)
+- Labels and descriptions required
+- Keyboard navigation essential
+- Focus must be visible
+
+**macOS (NSAccessibility):**
+- Controls expose accessibility attributes
+- VoiceOver announces all changes
+- Keyboard support required
+- Role and subrole must be set
+
+**Linux (AT-SPI2):**
+- DBus-based accessibility API
+- Screen reader (Orca) discovers objects
+- Action model (click, focus, etc.)
+- State reporting (enabled, pressed, etc.)
+
+**Using `@desktop-a11y-specialist`:**
+
+```
+User: @desktop-a11y-specialist test my-app --platform windows
+
+Agent response:
+1. Checks Windows accessibility:
+   - UIA object properties
+   - Keyboard navigation
+   - Focus indicators
+   - Screen reader compatibility (NVDA)
+2. Runs NVDA simulation:
+   - Lists all controls as NVDA sees them
+   - Checks announced names and roles
+3. Reports:
+   - Button not announcing name ("win1234" instead of "Save")
+   - Tab order incorrect
+   - Status bar text not announced
+```
+
+### NVDA Add-on Development
+
+NVDA (free, open-source screen reader) supports add-ons for extended functionality.
+
+**NVDA add-on structure:**
+
+```
+my-addon/
+├── addon/
+│   ├── globalPlugins/
+│   │   └── myPlugin.py         # Main plugin code
+│   ├── brailleDisplayDrivers/  # Optional: Braille driver
+│   ├── synthDrivers/           # Optional: Speech driver
+│   └── appModules/             # Optional: App-specific code
+├── buildVars.py                # Version, author, description
+├── manifest.ini                # Add-on metadata
+└── readme.md                   # Documentation
+```
+
+**Using `@nvda-addon-developer`:**
+
+```
+User: @nvda-addon-developer create an add-on that improves announcement of custom web components
+
+Agent response:
+1. Scaffolds project structure
+2. Creates sample globalPlugin
+3. Provides template for:
+   - Event handling (focus, name change)
+   - Custom announcements
+   - Keyboard shortcuts
+4. Includes testing guidance with NVDA emulator
+```
+
+**Example NVDA Add-on Snippet:**
+
+```python
+# my-addon/addon/globalPlugins/myPlugin.py
+import globalPluginHandler
+import api
+from ui import message
+
+class GlobalPlugin(globalPluginHandler.GlobalPlugin):
+    def event_gainFocus(self, obj, nextHandler):
+        # Announce when custom component gets focus
+        if hasattr(obj, "customRole"):
+            message(f"Custom {obj.customRole}: {obj.name}")
+        nextHandler()
+```
+
+## 7. CI/CD Integration for Accessibility
+
+### Accessibility in GitHub Actions
+
+Add accessibility checks to your CI/CD pipeline:
+
+**Example: Lighthouse Accessibility Check**
+
+```yaml
+# .github/workflows/accessibility.yml
+name: Accessibility Check
+
+on: [push, pull_request]
+
+jobs:
+  accessibility:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - uses: actions/setup-node@v3
+        with:
+          node-version: '18'
+      - run: npm install
+      - run: npm run build
+      
+      # Run Lighthouse audit
+      - uses: actions/upload-artifact@v3
+        with:
+          name: lighthouse-report
+          path: lighthouse-results.json
+      
+      # Post results as PR comment
+      - name: Comment PR with results
+        uses: actions/github-script@v6
+        with:
+          script: |
+            const fs = require('fs');
+            const results = JSON.parse(fs.readFileSync('lighthouse-results.json'));
+            const a11yScore = results.categories.accessibility.score * 100;
+            github.rest.issues.createComment({
+              issue_number: context.issue.number,
+              owner: context.repo.owner,
+              repo: context.repo.repo,
+              body: `## Accessibility Score: ${a11yScore}/100`
+            });
+```
+
+**Using `@ci-accessibility`:**
+
+```
+User: @ci-accessibility add-workflow my-repo
+
+Agent response:
+1. Analyzes current CI/CD setup
+2. Creates workflow file:
+   - Lighthouse audit on each PR

+   - Posts results to PR comments
+3. Configures thresholds:
+   - Error: < 70 (blocks merge)
+   - Warning: 70-79 (notify but allow)
+   - Success: ≥ 80 (approve)
+```
+
+### Playwright Accessibility Testing
+
+**Example: Keyboard Navigation Test**
+
+```typescript
+// tests/keyboard.spec.ts
+import { test, expect } from '@playwright/test';
+
+test('form accessible by keyboard only', async ({ page }) => {
+  await page.goto('https://example.com/form');
+  
+  // Tab through form without mouse
+  await page.keyboard.press('Tab');
+  expect(await page.locator('#name').evaluate(el => el === document.activeElement)).toBeTruthy();
+  
+  // Type in focused field
+  await page.keyboard.type('Jane Doe');
+  await page.keyboard.press('Tab');
+  
+  // Verify focus moved to email field
+  expect(await page.locator('#email').evaluate(el => el === document.activeElement)).toBeTruthy();
+  
+  // Submit via keyboard
+  await page.keyboard.press('Tab');  // Navigate to Submit
+  await page.keyboard.press('Enter'); // Submit
+  
+  // Verify submission
+  expect(page).toHaveURL('/success');
+});
+```

+## 8. VS Code 1.120 Chat, Agents Window, and Markdown Diff Updates
+
+VS Code 1.120 adds several accessibility-relevant changes for learners who use Copilot, review documentation diffs, or manage agent sessions. For the full Copilot and Agents window workflow, see [Appendix K: VS Code 1.120 Agents Window and Impactful Updates](appendix-k-copilot-reference.md#4a-vs-code-1120-agents-window-and-impactful-updates).
+
+### What Changed
+
+The following table summarizes the 1.120 changes that affect accessible VS Code workflows.
+
+| Feature | Accessibility Impact | Suggested Use |
+| ------- | -------------------- | ------------- |
+| Agents window, Preview | Gives agent sessions their own window with sessions, chat, customizations, files, and changes | Use Command Palette access, worktree isolation, and Changes panel review |
+| Terminal command risk assessment, Experimental | Adds a risk badge and command explanation to some terminal confirmations | Treat as extra context, not permission to skip reading the command |
+| Terminal output compression, Preview | Reduces long terminal output sent to chat, which can reduce context noise | Use for large diffs or install logs; ask for raw output when exact text matters |
+| Markdown preview for diffs, Preview | Lets documentation diffs render as Markdown instead of only source text | Useful for sighted and low-vision review of headings, lists, links, and tables |
+| Plan mode inline control | Lets supported agents show and edit plans inline before implementation | Useful when reviewing an agent plan before file changes start |
+| Model picker grouped by provider | Makes model lists easier to scan when many models are available | Keep beginners on Auto; use provider grouping for advanced model selection |
+| BYOK token usage and thinking effort | Gives advanced users more visibility and control for bring-your-own-key models | Not needed for beginners; useful for cost and context management |
+| Markdown HTML `id` completion and validation | Improves completion and validation for internal links to HTML IDs in Markdown | Helpful when maintaining long workshop docs with many anchors |
+| Smart select for Markdown tables | Expands selection from cell to row to whole table | Helpful for keyboard users editing large reference tables |
+
+### Screen Reader Workflow
+
+1. Open the Agents window with **Chat: Open Agents Window** from the Command Palette.
+2. Use `Alt+F1` in the focused area to find context-specific accessibility help.
+3. Use `F6` and `Shift+F6` to move among major workbench parts.
+4. Use `Alt+F2` for Accessible View when chat responses, terminal output, hovers, or diffs are easier to read in a stable buffer.
+5. Use `F7` and `Shift+F7` for diff navigation before accepting agent changes.
+6. When terminal risk assessment is enabled, listen to the risk label and explanation, then still read the exact command before approving it.
+
+### Low Vision Workflow
+
+1. Set zoom and theme before starting a dense Agents window session.
+2. Use modal diff view when side-by-side changes are too compressed.
+3. Try Markdown preview diffs for documentation changes where rendered headings, lists, and tables are easier to inspect.
+4. Widen the Sessions list, Chat area, and Changes panel as needed before reviewing work.
+5. Consider separate Agents window settings if your editor and agent review layouts need different zoom or density.
+
+### Sighted Workflow
+
+1. Use changed-file counts and session status badges as quick scope checks.
+2. Open each changed file from the Changes panel before accepting a session result.
+3. Use rendered Markdown diffs for documentation PRs and source diffs for syntax-sensitive edits.
+4. Use the integrated browser or terminal in the Agents window to validate generated work before committing or merging.
+
+### Settings Reference
+
+The following settings are useful to know when teaching VS Code 1.120 workflows.
+
+| Setting | What It Controls |
+| ------- | ---------------- |
+| `chat.tools.riskAssessment.enabled` | Shows risk assessment for terminal command confirmations |
+| `chat.tools.compressOutput.enabled` | Compresses large terminal output before it is sent to the model |
+| `chat.planWidget.inlineEditor.enabled` | Enables inline plan editing for supported agent flows |
+| `workbench.diffEditorAssociations` | Can set rendered Markdown preview as the default diff editor for Markdown |
+| `extensions.supportAgentsWindow` | Lets you opt specific installed extensions into the Agents window |
+| `chat.notifyWindowOnResponseReceived` | Controls OS notifications when chat responses arrive |
+| `chat.notifyWindowOnConfirmation` | Controls OS notifications when an agent needs confirmation |
+
+Example setting for rendered Markdown diffs:
+
+```json
+{
+  "workbench.diffEditorAssociations": {
+    "*.md": "vscode.markdown.preview.editor"
+  }
+}
+```

+## 4A. VS Code 1.120+ Agents Window and Accessibility: Complete Guide
+
+### Agents Window (Agent-First Workflow)
+
+VS Code 1.120 introduces the **Agents window** (Preview, now Stable) for agent-first workflows. This dedicated window lets you:
+
+- Orchestrate tasks across multiple projects and workspaces
+- Track, review, and manage agent sessions (Copilot CLI, Copilot Cloud, Claude)
+- Access a Customizations panel for agent personas, skills, hooks, MCP servers, and plugins
+- Use an integrated browser and terminal for validating agent changes
+- Start sessions on remote machines (SSH, dev tunnel)
+- Create sub-sessions for parallel tasks in the same workspace
+- Review all agent changes before committing, merging, or discarding
+- Use extension support (static content auto-activates, others opt-in via `extensions.supportAgentsWindow`)
+
+#### Key Features
+
+| Feature | Description |
+|---------|-------------|
+| Agent-first workflow | Dedicated window for describing tasks, tracking sessions, reviewing changes |
+| Session management | Manage, pin, filter, and review sessions across all workspaces |
+| Customizations | Direct access to agent personas, skills, hooks, MCP servers, plugins |
+| Integrated browser | Validate web changes in a persistent browser tab |
+| Remote/dev tunnel | Start agent sessions on remote machines via SSH or dev tunnel |
+| Sub-sessions | Parallel tasks in the same workspace (except Claude agent) |
+| Extension support | Many extensions work; opt-in for others via settings |
+| Markdown diff preview | Review documentation changes visually, with smart selection and HTML id validation |
+| Risk assessment | Terminal commands show AI-generated risk badges (safe, caution, review carefully) |
+| Output compression | Large terminal output is compressed to save context window space |
+| BYOK support | Bring-your-own-key models (OpenAI, Anthropic, etc.) with token usage and thinking effort controls |
+| Accessibility | Accessible View, keyboard navigation, screen reader/low vision/sighted workflows |
+
+#### How to Open the Agents Window
+
+1. Select **Open in Agents** from the VS Code title bar
+2. Open the Command Palette and run **Chat: Open Agents Window**
+3. Run `code --agents` from a terminal
+
+#### Interface Overview
+
+| Area | What It Contains |
+|------|------------------|
+| Sessions list | All agent sessions across workspaces |
+| Customizations panel | Agents, skills, instructions, hooks, MCP servers, plugins |
+| Chat area | Conversation and prompts for the selected session |
+| Changes panel | Files tab (explorer) and Changes tab (agent edits, diffs, feedback, commit/merge/discard) |
+
+#### Safe Review Workflow
+
+1. Open the Agents window
+2. Start a new session (Ctrl+N)
+3. Choose workspace/repo, trust folder if prompted
+4. Select agent type (Copilot CLI, Cloud, Claude)
+5. Prefer **worktree isolation** for Git projects (keeps agent edits separate until review)
+6. Use Files panel sync before agent starts to pull upstream changes
+7. Type a clear, single task
+8. Review all changes in the Changes panel before accepting
+9. Run validation tasks (build, test) as needed
+10. Commit, merge, or discard only after review
+
+#### Accessibility and Inclusion
+
+- **Accessible View**: Press `Alt+F2` for screen reader-friendly suggestion review and insertion
+- **Keyboard navigation**: All panels and controls are keyboard accessible
+- **Screen reader/low vision/sighted workflows**: See learning cards below for detailed guidance
+- **Markdown diff preview**: Use for documentation changes; supports smart selection and HTML id validation
+
+#### Learning Cards: Agents Window

+
+</details>
+
+#### Other VS Code 1.120+ Features to Highlight
+
+| Feature | Why It Matters | Workshop Guidance |
+|---------|---------------|-------------------|
+| Terminal command risk assessment | AI-generated risk badges for terminal commands | Useful for all users; always review command details |
+| Output compression | Summarizes large terminal output | Saves context window space; ask for raw output if needed |
+| Markdown diff preview | Visual review of documentation changes | Use for PRs, especially with headings/tables |
+| Plan mode inline control | Edit plans before agent starts work | Use for complex features or when validating approach |
+| BYOK token usage/thinking effort | Track/manage model context/cost | Advanced users only; defaults are safe |
+| Model picker by provider | Easier model selection | Start with Auto; use provider grouping as needed |
+| Copilot CLI plugin discovery | Plugins auto-discovered in VS Code | Reduces setup for advanced users |
+| Markdown HTML id completion/validation | Easier anchor link management | Useful for long docs with many anchors |
+| Smart selection for Markdown tables | Expand selection from cell to row/table | Helpful for keyboard/low vision users |
+
+#### Settings and Limitations
+
+| Setting | Status | Description |
+|---------|--------|-------------|
+| `chat.tools.riskAssessment.enabled` | Experimental | AI risk labels for terminal commands |
+| `chat.tools.compressOutput.enabled` | Preview | Compresses large terminal output |
+| `chat.planWidget.inlineEditor.enabled` | Current | Inline plan editing for supported agents |
+| `workbench.diffEditorAssociations` | Current | Markdown files open with preview diffs |
+| `extensions.supportAgentsWindow` | Preview | Opt-in extensions for Agents window |
+| `chat.notifyWindowOnResponseReceived` | Current | OS notifications for chat responses |
+| `chat.notifyWindowOnConfirmation` | Current | OS notifications for agent input/confirmation |
+
+**Limitations:**
+- Agents window is Preview in 1.120; not all agent types/extensions supported
+- Multi-root sessions not yet supported
+- Some extensions require opt-in
+- Agent cannot directly open integrated browser (use localhost link or command)
+- Org policy may restrict agents/cloud/model choices
+
+#### Placement in the Workshop
+
+Introduce the Agents window after learners complete Chat and Agent mode in [Chapter 16](16-github-copilot.md). Use it as an advanced review and orchestration surface, not a replacement for learning Git, diffs, PRs, and manual accessibility review.
+
+### Other VS Code 1.120 Changes Worth Calling Out
+
+The following VS Code 1.120 release-note items are most relevant to this workshop.
+
+| Feature | Why It Matters | Workshop Guidance |
+| ------- | -------------- | ----------------- |
+| Terminal command risk assessment, Experimental | Command confirmations can include a risk badge and a short explanation of what the command does | Useful for beginners and screen reader users, but still read the full command yourself before approving |
+| Terminal tool output compression, Preview | Long terminal output can be summarized before it enters chat context | Helpful for large `git diff`, install, and test logs; ask for raw output if exact lines matter |
+| Markdown preview for diffs, Preview | Markdown diffs can be reviewed as rendered content instead of only raw source | Useful for documentation PRs, especially when headings, lists, and tables matter visually |
+| Plan mode inline control for Claude and Copilot CLI | Plans can be edited inline before implementation starts | Use this when you want learners to shape the plan before the agent edits files |
+| BYOK token usage in Chat | Bring-your-own-key models now show more accurate context-window usage | Helpful for advanced users managing context and cost; not required for workshop beginners |
+| BYOK thinking effort controls | Reasoning models can expose thinking-effort settings from the model picker | Advanced setting only; leave defaults unless a facilitator gives specific guidance |
+| Model picker grouped by provider | Models are organized by provider and searchable by name | Tell learners to start with Auto and use provider grouping only when they must choose a specific model |
+| Copilot CLI plugin discovery | Plugins installed with GitHub Copilot CLI can be picked up by VS Code | Reduces duplicate setup for advanced agent users; document only as a convenience note |
+| Markdown HTML `id` completion and validation | Markdown links to HTML `id` anchors are easier to complete and validate | Useful for this repo because long docs use many internal anchors |
+| Smart selection for Markdown tables | Expand Selection can grow from a cell to a row and then the whole table | Helpful when editing large reference tables with keyboard or low vision workflows |
+
+### Recommended Settings to Know
+
+The following table lists settings that matter for this 1.120 update.
+
+| Setting | Status | What It Does |
+| ------- | ------ | ------------ |
+| `chat.tools.riskAssessment.enabled` | Experimental | Shows AI-generated risk labels for terminal command confirmations |
+| `chat.tools.compressOutput.enabled` | Preview | Compresses large terminal output before it is sent to the model |
+| `chat.planWidget.inlineEditor.enabled` | Current | Controls inline plan editing for supported agents |
+| `workbench.diffEditorAssociations` | Current | Can make Markdown files open with rendered Markdown preview diffs by default |
+| `extensions.supportAgentsWindow` | Preview | Opts specific installed extensions into the Agents window |
+| `chat.notifyWindowOnResponseReceived` | Current | Sends OS notifications when a chat response arrives |
+| `chat.notifyWindowOnConfirmation` | Current | Sends OS notifications when an agent needs input or confirmation |
+
+Example Markdown preview diff setting:
+
+```json
+{
+  "workbench.diffEditorAssociations": {
+    "*.md": "vscode.markdown.preview.editor"
+  }
+}
+```
+
+Example extension opt-in for the Agents window:
+
+```json
+{
+  "extensions.supportAgentsWindow": {
+    "publisher.extension-id": true
+  }
+}
+```
+
+### Limitations to Teach Explicitly
+
+- The Agents window is still a Preview feature in VS Code 1.120.
+- Not every agent type or third-party agent is supported in the Agents window yet.
+- Multi-root sessions are not supported in the Agents window yet.
+- Some extensions work automatically, but extension support is still evolving.
+- The agent cannot directly open the integrated browser for you; use a localhost link or **Browser: Open Integrated Browser**.
+- Organization policy can disable or limit agents, cloud agents, model choices, approvals, and BYOK features.
+
+### Recommended Placement in the Workshop
+
+Introduce the Agents window after learners complete the normal Chat and Agent mode flow in [Chapter 16](16-github-copilot.md). Treat it as an advanced navigation and review surface, not a replacement for learning Git, diffs, pull requests, and manual accessibility review.
+
+## 4B. MCP Servers - Accessibility Scanning Tools
+
+Model Context Protocol (MCP) servers expose accessibility scanning tools that work with any MCP-compatible client - VS Code, Claude Desktop, other MCP-aware tools, and CI/CD pipelines.
+
+### What is MCP?
+
+MCP is an open protocol (anthropic/model-context-protocol) that lets AI agents access tools and data sources through a standardized interface. The Accessibility Agents project operates an HTTP-based MCP server with 30+ accessibility tools - no installation needed, just connect and scan.
+
+**Benefits for accessibility work:**
+- Use the same tools across different AI platforms (Copilot, Claude, Gemini, CI/CD)
+- Tools work offline or in restricted environments via local HTTP server
+- Streaming responses with live progress updates
+- Compliance audit history and trending
+
+### Core 30+ MCP Tools Catalog
+
+**Web Accessibility Scanning (8 tools):**
+- `scan-page` - Scan a live URL with axe-core WCAG 2.2 AA rules
+- `scan-pages` - Batch scan multiple URLs
+- `scan-dom` - Scan raw HTML/DOM without loading a page
+- `scan-with-lighthouse` - Lighthouse accessibility audit
+- `scan-with-playwright` - Behavioral testing with Playwright
+- `get-page-outline` - Extract heading hierarchy and landmarks
+- `detect-color-contrast` - Analyze contrast ratios across a page
+- `find-aria-roles` - Map all ARIA roles and their state changes

+
+**Markdown & Content Scanning (4 tools):**
+- `scan-markdown` - Markdown file accessibility check
+- `lint-markdown` - Markdownlint rules with accessibility focus
+- `validate-links` - Check link structure and destinations
+- `check-headings` - Verify heading hierarchy and anchor links
+
+**Compliance & Reporting (5 tools):**

+- `post-audit-to-issue` - Comment audit results on a GitHub issue
+- `create-accessibility-pr` - Create PR with accessibility fixes
+- `trigger-ci-scan` - Start accessibility scanning in CI pipeline
+
+### How to Use MCP Tools in VS Code
+
+**Option 1: Via Copilot Chat (direct)**
+
+```text
+@workspace use the scan-page MCP tool to scan https://example.com
+```
+
+Copilot will recognize "scan-page" and invoke it through the MCP server.
+
+**Option 2: Via a custom agent**
+
+Create a `.github/agents/my-scanner.agent.md` that declares MCP tool access:
+
+```yaml
+---
+name: My Scanner
+description: Custom agent using MCP accessibility tools
+tools: ['scan-page', 'scan-word', 'export-findings-csv']
+---
+
+You have access to MCP accessibility scanning tools...
+```
+
+**Option 3: Via MCP server connection in settings**
+
+Add to `.vscode/settings.json`:
+
+```json
+{
+  "modelContext.servers": {
+    "accessibility-agents": {
+      "command": "node",
+      "args": ["path/to/mcp-server/index.js"],
+      "env": {
+        "PORT": "3000"
+      }
+    }
+  }
+}
+```
+
+### MCP Tools in CI/CD
+
+Use MCP tools in GitHub Actions to run accessibility scans on every commit:
+
+```yaml
+name: Accessibility Scan
+on: [push, pull_request]
+jobs:
+  scan:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - name: Run Accessibility Agents MCP server
+        run: npx @a11y-agent-team/mcp-server &
+      - name: Scan changed files
+        run: npx accessibility-agents scan --mcp-url http://localhost:3000
+```

+## 4C. Smart Actions
+
+**Smart Actions** are predefined AI-powered actions for common coding tasks. They appear as options when you click on code, errors, or use the lightbulb menu.
+
+### Available Smart Actions
+
+| Action | Trigger | What It Does |
+|--------|---------|-------------|
+| Generate Commit Message | Staged changes in Git | Creates a descriptive commit message from your staged diff |
+| Rename Symbol | Any symbol in code | Rename a variable/function and all references automatically |
+| Fix Error | Error inline squiggle | Suggests fixes for compilation, lint, or test errors |
+| Semantic Search | Selection in editor | Search your workspace for conceptually related code (not just text match) |
+| Document Code | Function or method | Generate docstrings and inline comments |
+| Refactor Code | Selection | Suggest refactoring patterns (extract function, simplify, etc.) |
+| Explain Code | Selection | Provide a plain-language explanation of selected code |
+
+### How to Trigger Smart Actions
+
+1. **Lightbulb menu:** Click the lightbulb icon in the left margin of the editor (or press `Ctrl+.`)
+2. **Git integration:** Stage changes with `git add`; the commit panel offers "Generate Commit Message"
+3. **Error squiggles:** Hover over an error and press `Ctrl+.` to see fixes
+4. **Keyboard shortcut:** `Ctrl+.` opens available actions for the current selection
+
+### Keyboard Shortcuts for Smart Actions
+
+| Action | Windows / Linux | macOS |
+|--------|-----------------|-------|
+| Open Smart Actions menu | `Ctrl+.` | `Cmd+.` |
+| Accept first suggestion | `Enter` | `Enter` |
+| Navigate menu | `Up/Down Arrow` | `Up/Down Arrow` |
+
+### Screen Reader & Low Vision Workflows
+
+<details>
+<summary>Screen reader users</summary>
+
+- When the lightbulb appears, VS Code announces it as a clickable action
+- Press `Ctrl+.` to open the actions list; it becomes a dropdown menu navigable with arrow keys
+- Each action is announced with a short description (e.g., "Generate Commit Message")
+- Press `Enter` to activate the selected action
+- Results appear as code suggestions or inline edits that you can review before accepting
+
+</details>
+
+<details>
+<summary>Low vision users</summary>
+
+- The lightbulb icon is visible in the left margin when actions are available
+- Increase zoom (`Ctrl+=`) to make the lightbulb and menu more visible
+- Use high-contrast theme to distinguish the lightbulb from surrounding text
+- The action menu can be wide; resize the editor panel if needed
+- Results are shown as code suggestions with "Accept" and "Reject" buttons
+
+</details>
+
+<details>
+<summary>Keyboard-only users</summary>
+
+- Press `Ctrl+.` from any position in the editor
+- Use `Up/Down Arrow` to navigate through available actions
+- Press `Enter` to activate; `Escape` to dismiss

+
+- Click the lightbulb icon that appears when actions are available
+- Browse the dropdown menu visually
+- Click an action to run it
+- Hover over actions to see descriptions
+
+</details>
+
+### Workshop Guidance
+
+Introduce Smart Actions as a shortcut for common tasks, but emphasize manual understanding first:
+- Teach learners to rename variables manually before showing "Rename Symbol"
+- Teach error-fixing patterns before showing "Fix Error"
+- Use "Generate Commit Message" as a review tool, not a replacement for writing meaningful messages
+
+---
+
+## 4D. Browser Agent (Experimental)
+
+**Browser Agent (Experimental)** lets your Copilot agent test and validate web applications directly. The agent can open your app in the integrated browser, verify features, check for layout issues, and take screenshots.
+
+### What the Browser Agent Can Do
+
+- Open a web app (local or remote) in the integrated browser
+- Verify that a feature works as expected
+- Check for layout or visual issues
+- Take screenshots for documentation
+- Navigate forms and test user flows
+- Report accessibility or functionality issues
+
+### How to Use Browser Agent
+
+1. Start a Copilot agent session (Chat or Agents window)
+2. Ask the agent to test your web app:
+   ```text
+   Open the web app at localhost:3000 and verify the login form works correctly.
+   ```
+3. The agent opens the integrated browser automatically
+4. It interacts with the page and reports findings
+5. Review results in Chat and take action as needed
+
+### Example Prompts
+
+```text
+Open http://localhost:3000 and take a screenshot of the homepage.
+
+Test the search form at localhost:8080 - enter "accessibility" and verify results appear.
+
+Check the mobile layout of localhost:3000 at 320px width and report any overlapping text.
+
+Verify the light and dark mode toggle works on localhost:3000.
+```
+
+### Important: Browser Agent is Experimental
+
+- Feature availability may change
+- Not all browsers or endpoints are supported
+- Use only with development servers you control
+- Results may require human verification
+- Do not rely on Browser Agent alone for accessibility or security testing
+
+### Accessibility & Testing Considerations
+
+<details>
+<summary>Screen reader users</summary>
+
+- Browser Agent interactions are reported in Copilot Chat as text descriptions
+- Press `Alt+F2` to read the full response in Accessible View
+- Screenshots taken by the agent appear as images in Chat (not screen-reader friendly)
+- Request text descriptions instead: "Describe what you see on the page instead of taking a screenshot"
+
+</details>
+
+<details>
+<summary>Low vision users</summary>
+
+- Browser Agent can zoom the test environment independently of your VS Code zoom
+- Request large screenshots: "Take a screenshot at 150% zoom"
+- Increase Chat panel zoom to read agent responses
+- Use high-contrast mode for the integrated browser
+
+</details>
+
+<details>
+<summary>Keyboard-only users</summary>
+
+- All Browser Agent interactions are text-based in Chat
+- You cannot directly interact with the integrated browser keyboard-only (it's agent-driven)
+- Request text interaction: "Use the keyboard to navigate the form and tab through fields"
+
+</details>
+
+<details>
+<summary>Sighted users</summary>
+
+- Browser Agent opens the integrated browser as a visible panel
+- Watch the agent interact with your app in real time
+- Screenshots are useful for documentation or layout verification
+
+</details>
+
+### Workshop Guidance
+
+- Treat Browser Agent as a supplementary testing tool, not a replacement for manual testing
+- Teach learners to write clear test descriptions: "Check for visible text overlaps" vs. "Is it broken?"
+- Use sparingly; each agent session consumes model tokens
+- For accessibility testing, prefer manual screen reader / keyboard testing + Browser Agent screenshots
+
+---
+
+## 4E. Plan Agent
+
+The **Plan Agent** is a specialized Copilot agent that breaks down a task into a structured implementation plan before writing code. It analyzes your codebase, asks clarifying questions, and produces a step-by-step plan that you can review and refine before implementation starts.
+
+### How Plan Agent Works
+
+1. **Start an agent session** and describe your task
+2. **Plan Agent** analyzes your codebase structure and conventions
+3. **Asks clarifying questions** to understand requirements ("Should this use TypeScript or JavaScript?")
+4. **Generates a plan** with concrete steps, file changes, and testing approach
+5. **You review and edit** the plan inline (if editing is enabled)
+6. **Handoff to implementation** - either Plan Agent or another agent executes the plan
+7. **Agent runs tests** and reports success or asks for refinement
+
+### Example Workflow
+
+```text
+Prompt: "Add a new feature that lets users export data as CSV."
+
+Plan Agent asks:
+- Where should the CSV export button go in the UI?
+- Should we use an existing CSV library or write our own?
+- Do we need to support large files or streaming?
+
+Plan generates:
+- Step 1: Create export utility in lib/export.ts
+- Step 2: Add button to UI component
+- Step 3: Wire button to export function
+- Step 4: Add tests for export logic
+- Step 5: Test with large dataset
+
+You review and edit the plan → Agent implements → Tests run → Feature complete
+```
+
+### Plan Agent vs. Full Implementation Agent
+
+| Aspect | Plan Agent | Implementation Agent |
+|--------|-----------|----------------------|
+| **Purpose** | Breaks down complex tasks into steps | Executes the full task end-to-end |
+| **Interaction** | Reviews and refines plan before coding | Codes as it goes |
+| **Best for** | Large features, unfamiliar codebases, design review | Well-scoped tasks, known patterns |
+| **Control** | Plan can be edited inline | Limited control once coding starts |
+| **Time** | Slower upfront, faster overall if plan is good | Faster initial, may need rework |
+
+### When to Use Plan Agent
+
+- Complex features requiring multi-file changes
+- Unfamiliar codebases where structure isn't obvious
+- When design review is important before implementation
+- When you want to validate the approach before committing
+- Team workflows where plan review is a step before coding
+
+### Keyboard Shortcuts for Plan Agent
+
+| Action | Windows / Linux | macOS |
+|--------|-----------------|-------|
+| Open Agents window | `Code --agents` or Command Palette | Same |
+| Start new session | `Ctrl+N` | `Cmd+N` |
+| Edit plan inline (if enabled) | Click edit button or `Tab` into plan | Same |
+| Send plan for implementation | `Ctrl+Enter` | `Cmd+Enter` |
+
+### Accessibility & Planning Workflows

+</details>
+
+### Workshop Guidance
+
+Introduce Plan Agent as a **design-first** approach:
+- Use it for larger features or refactors
+- Teach learners to ask clarifying questions back to the plan
+- Emphasize code review: "Is this plan what you expected?"
+- Use Plan Agent output as documentation for your team

+## 4F. Copilot Spaces - Team Knowledge Base
+
+**Copilot Spaces** (in preview) lets teams create a shared knowledge base that Copilot uses when answering questions. A Space includes documentation, codebases, and domain knowledge, all indexed for fast retrieval by AI.
+
+### What is a Copilot Space?
+
+A **Space** is a collection of:
+- Project documentation
+- Code repositories
+- Architectural guides
+- API documentation
+- Team conventions and style guides
+- Links to external resources
+
+When someone uses Copilot in the Space, the AI uses that knowledge to provide more accurate, context-aware answers.
+
+### Why Copilot Spaces Matter
+
+- **Consistency**: All team members get answers grounded in the same authoritative sources
+- **Onboarding**: New team members get expert-level context immediately
+- **Domain expertise**: Copilot learns your project's conventions, architecture, and best practices
+- **Reduced hallucinations**: Fewer wrong or outdated answers
+
+### How to Create a Copilot Space
+
+1. Go to [github.com/copilot/spaces](https://github.com/copilot/spaces)
+2. Click **Create a new Space**
+3. Name your Space (e.g., "My Project Team")
+4. Add repositories and documentation:
+   - Link GitHub repositories
+   - Add documentation links (GitHub Pages, wikis, external docs)
+   - Upload or reference team guides
+5. Configure access (public, private, organization-only)
+6. Save and share the Space URL with your team
+
+### Using a Copilot Space
+
+1. Open Copilot Chat in VS Code or GitHub
+2. Select your Space from the Space picker (top of Chat)
+3. Ask questions - Copilot uses the Space knowledge
+4. Example:
+   ```text
+   We're adding a new API endpoint. What patterns does our team use in src/api/?
+   ```
+5. Copilot searches the Space and returns context-aware answers
+
+### Accessibility & Team Workflows

+### GitHub.com Cloud Agents and Third-Party Agent Assignment
+
+On GitHub.com, you can assign tasks to different AI agents, including third-party agents from other providers:
+
+| Agent | Provider | How to Use |
+|-------|----------|----------|
+| **Copilot Agent** | GitHub | Default agent; assign to GitHub issues/PRs by @-mentioning `@copilot` |
+| **Claude by Anthropic** | Anthropic | Assign to issues/PRs; must be enabled by organization |
+| **OpenAI Codex** | OpenAI | Assign to issues/PRs; BYOK (bring-your-own-key) required |
+
+### Workflow: Assigning Tasks to Cloud Agents on GitHub
+
+1. Open an issue or pull request on GitHub.com
+2. Click **Assignees** in the right panel
+3. Search for the agent name (`@copilot`, `@claude`, etc.)
+4. Select the agent
+5. Add a comment describing the task:
+   ```
+   @copilot please implement this feature and open a PR.
+   ```
+6. The agent reads the issue, makes a plan, creates a branch, implements, and opens a PR
+7. Review the agent's PR changes before merging
+
+### Example Scenarios
+
+**Scenario 1: Copilot cloud agent for bug fix**
+- Assign a GitHub issue to `@copilot`
+- Add details about the bug
+- Copilot creates a branch, reproduces the bug, fixes it, and opens a PR
+
+**Scenario 2: Claude agent for documentation**
+- Assign `@claude` to improve project docs
+- Claude writes expanded documentation, tests examples, opens a PR
+
+**Scenario 3: Codex agent for refactoring**
+- If your organization has Codex access, assign `@codex` to refactor old code
+- Codex modernizes the code and opens a PR
+

+- Agent PRs show file changes with diff highlighting (green/red)
+- Comments from the agent are marked with the agent's profile
+- Use the Merge button once review is complete
+
+</details>
+
+### Workshop Guidance
+
+- Cloud agents are powerful for real-world workflows, but the workshop focuses on **understanding** the underlying concepts first
+- Teach learners to review agent PRs carefully - they're still AI-generated and need human judgment
+- Show an example: "Here's a PR created by Copilot Cloud. Notice the changes and think about whether they match the original requirements."
+- Emphasize: Agents are accelerators, not replacements for code review
+
 The AI agent (GitHub Copilot, Claude, or OpenAI Codex) reads your repository context and the natural language instructions, then performs the task using the GitHub MCP Server and other available tools.

+## 15. Copilot Pricing, Free Plan, and Usage Limits
+
+> **IMPORTANT:** GitHub Copilot moved to **usage-based billing** on **June 1, 2026**. Premium request units were replaced by GitHub AI Credits. Verify current pricing and plan limits at [GitHub Copilot Plans](https://github.com/features/copilot/plans) before the workshop.
+
+### Copilot Plans (May 2026 Snapshot)
+
+| Plan | Monthly Cost | Included Usage | Features | Best For |
+|------|--------------|----------------|----------|----------|
+| **Free** | $0 | 50 completions, 2K chat tokens/month | Basic Copilot Chat, inline suggestions, limited chat | Getting started, light workshops |
+| **Pro** | $10 / month | Unlimited completions, higher chat limits | Full Chat, Copilot CLI, custom instructions | Individual developers |
+| **Pro+** | $39 / month | Unlimited all features | All Pro + agents, Copilot Cloud, Codex models | Complex workflows, agentic development |
+| **Team** | $35 / seat / month (min 2 seats) | Org-managed limits | Team governance, Copilot Spaces, audit logging | Teams and organizations |
+| **Enterprise** | Custom | Custom | Full customization, SSO, compliance | Large organizations |
+
+**Source:** [GitHub Copilot Plans](https://github.com/features/copilot/plans) (updated May 2026)
+
+### Free Plan Details and Workshop Considerations
+
+**Copilot Free** is a zero-cost plan with limited monthly usage. It's suitable for learning, but facilitators should be aware of the constraints:
+
+#### Free Plan Limits (May 2026)
+
+| Feature | Limit |
+|---------|-------|
+| Completions (ghost text suggestions) | 50 per month |
+| Chat messages (Copilot Chat) | 2,000 context tokens total per month |
+| Inline Chat (`Ctrl+I`) | Counts against chat limit |
+| Agent requests | Not included - Free plan cannot run agents |
+| Custom instructions | Available, but limited context |
+| Models | Auto selection only; cannot manually choose models |
+
+#### Free Plan Restrictions
+
+- **No agent support:** If your workshop uses agents (e.g., `@web-accessibility-wizard`), Free plan users cannot participate in those exercises
+- **Chat limits can be reached quickly:** 2K tokens is roughly 3-5 multi-turn chat conversations depending on context size
+- **No Copilot CLI:** Free plan users cannot use the Copilot CLI for command-line assistance
+- **No Copilot Cloud:** Cannot run cloud-based agentic workflows
+- **Resets monthly:** Limits reset at the start of each month
+
+#### Workshop Guidance for Free Plan Users
+
+If your workshop has Free plan participants:
+
+1. **Pre-workshop communication:** Explain the limits and suggest they upgrade temporarily for paid plans' benefits
+2. **Task design:** Use short, focused prompts that consume fewer tokens
+3. **Alternative: Education benefits:** Verified students may be eligible for [GitHub Education](https://education.github.com) benefits including free Copilot Pro
+4. **Time management:** Encourage learners to plan their chat questions before asking to avoid wasted tokens
+5. **Completion workflow:** Teach local inline suggestions first (ghost text), then introduce Chat later to preserve the monthly limit
+
+### Copilot Pro Comparison: When to Recommend an Upgrade
+
+Recommend **Copilot Pro** ($10/month) for workshops if:
+- Your exercises involve Copilot Chat extensively
+- You want learners to experiment freely without token anxiety
+- The workshop lasts multiple days (Free plan limits reset monthly, but daily resets don't exist)
+- You use custom instructions or multiple models
+
+Many learners find the $10/month cost is worthwhile to remove friction during intensive learning.
+
+### Usage-Based Billing and GitHub AI Credits (Post June 1, 2026)
+
+On June 1, 2026, GitHub Copilot switched from **Premium Request Units** (PRUs) to **GitHub AI Credits**.
+
+#### Credit Pricing
+
+- **1 GitHub AI Credit = $0.01 USD**
+- Costs vary by model and input/output token consumption
+- Cached context may receive discounts
+- Code completions (ghost text) remain free for paid plans
+
+#### What Consumes AI Credits
+
+| Feature | Consumes Credits |
+|---------|------------------|
+| Copilot Chat | Yes |
+| Inline Chat (`Ctrl+I`) | Yes |
+| Copilot CLI | Yes |
+| Agent requests (`@copilot`, etc.) | Yes |
+| Copilot Cloud (GitHub.com) | Yes |
+| Copilot Spaces | Yes |
+| Code completions (Pro+) | No |
+| Code completions (Free) | No |
+
+#### Managing Usage
+
+Users see their credit consumption in [GitHub Settings - Copilot](https://github.com/settings/copilot) under Usage & Billing.
+
+**Tips for facilitators:**
+- Advise learners to monitor their usage if they're on a limited plan
+- Set expectations: "A typical multi-turn chat conversation costs 5-50 credits depending on the model"
+- Recommend Auto model selection to balance quality and cost
+- Mention monthly resets if learners are concerned about billing

-## 4. Customization Primitives - Decision Guide
-
-Before creating any file, choose the right primitive for the job. Each primitive is a different file type with a different purpose, scope, and trigger.
-
-| Primitive | File Type | When to Use |
-| -----------  | -----------  | -------------  |
-| **Always-on instructions** | `copilot-instructions.md`, `AGENTS.md`, `CLAUDE.md` | Standards that apply to every request - coding conventions, project context, tone |
-| **File-based instructions** | `*.instructions.md` | Rules that only apply to specific file types or folders - Python style, test conventions, docs standards |
-| **Prompts / Slash Commands** | `*.prompt.md` | Single repeatable task invoked with `/command` - scaffolding, triage, PR prep |
-| **Agent Skills** | `SKILL.md` in a named folder | Multi-step workflow with bundled scripts and reference files - testing, deployment, auditing |
-| **Custom Agents** | `*.agent.md` | Specialized persona with tool restrictions - orchestrates tasks, can invoke subagents |
-| **Hooks** | `*.json` | Deterministic lifecycle automation - block dangerous commands, run formatters, enforce policy |
-| **Personal Preferences** | `preferences.md` | Accessibility Agents fork-local personal settings - repos, output format, timezone |
-
-### Choosing Between Primitives
-
-#### Instructions vs Agent?
-
-- Instructions guide behavior passively (always-on or file-scoped). Agents perform tasks actively (on-demand, tool-using).
-
-#### Prompt vs Agent?
+| `/pr-comment`        | Draft a response to a PR comment |
+| `/pr-report`         | Detailed PR analysis report |
+| `/project-status`    | GitHub Projects board overview - columns, blocked, stale |
+| `/react`             | Suggest or add a reaction to an issue or comment |
+| `/refine-issue`      | Improve issue title, description, and labels |
+| `/release-prep`      | Complete release preparation workflow |
+| `/review-pr`         | AI-generated review with inline suggestions |
+| `/security-dashboard`| Dependabot alerts and vulnerability status |
+| `/sprint-review`     | End-of-sprint summary with velocity and retrospective |
+| `/team-dashboard`    | Team activity and contribution overview |
+| `/triage`            | Triage a new issue with label and priority suggestions |
 
-- Use a prompt for a single focused task you invoke explicitly. Use an agent when the task spans multiple steps, needs different tools, or should work as a subagent for other agents.
+## 4. Customization Primitives and File Formats
 
-#### Prompt vs Skill?
+See [Appendix K: Copilot Reference](appendix-k-copilot-reference.md) for a full guide to customization primitives, file formats, and always-on/file-based instructions.
 
-- Both appear as `/` slash commands. Use a prompt for one well-defined task. Use a skill when the workflow bundles scripts, templates, or reference docs alongside the instructions.
+## 5. Learning Cards: Agent Invocation, Skills, and Cross-Platform Support
 
-#### Instructions vs Hooks?
-
-- Instructions *guide* the agent (non-deterministic). Hooks *enforce* behavior via shell commands at lifecycle events - they run regardless of what the agent was prompted to do.
+<details>
+<summary>Screen reader users</summary>
 
+- All agents and skills are invoked by name with the `@` prefix (e.g., `@web-accessibility-wizard`).
+- Use the slash command menu (`/`) to discover available prompts and skills.
+- Agent output is rendered as Markdown tables and lists; use `Alt+F2` for Accessible View.
+- Skills are documented in `.github/skills/<name>/SKILL.md` and referenced in agent output.
+- Platform support is shown in agent/skill tables; check for Copilot, Claude, Gemini, Codex, CI/CD icons or text.

-- The Q&A comparisons (Instructions vs Agent, Prompt vs Skill, etc.) appear as bold subheadings -- skim them to resolve common ambiguities
-- If in doubt, start with a `.prompt.md` file for a focused task; graduate to `.agent.md` only when you need multi-step tool orchestration

+## 14. Smart Actions, Browser Agent, and Third-Party Agents
+
+### Smart Actions and Accessibility Agents
+
+VS Code 1.120+ introduces **Smart Actions** (automated suggestions for commit messages, symbol renaming, error fixing, and semantic search). These complement Accessibility Agents by automating routine tasks that don't require conversational reasoning.
+
+**Workflow:** Use Smart Actions (` Ctrl+.`) for quick fixes and accessibility agents (`` `@accessibility-lead` ``, `` `@wcag-guide` ``) for audits, explanations, and strategic guidance.
+
+| Use Smart Actions For | Use Accessibility Agents For |
+|----------------------|------------------------------|
+| Generate commit messages | Plan complex refactoring |
+| Rename variables consistently | Full WCAG 2.2 audits |
+| Fix linting errors | Custom accessibility rules |
+| Find related code quickly | Detailed remediation guidance |
+| Repair broken imports | Document compliance mapping |
+
+See [Appendix K: Smart Actions](appendix-k-copilot-reference.md#4c-smart-actions) for keyboard shortcuts and accessibility workflows.
+
+### Browser Agent and Accessibility Testing
+
+The **Browser Agent (Experimental)** can open and test web applications, but it requires human verification for accessibility claims. Pair Browser Agent with manual screen reader testing and structured Accessibility Agents audits.
+
+**Best practice workflow:**
+1. Use Browser Agent to take screenshots and verify layout (quick visual check)
+2. Use `` `@web-accessibility-wizard` `` to run structured audit (axe-core, semantic analysis)
+3. Do manual screen reader + keyboard testing to verify agent findings
+4. Use Accessibility Agents for remediation guidance and compliance mapping
+
+See [Appendix K: Browser Agent (Experimental)](appendix-k-copilot-reference.md#4d-browser-agent-experimental) and [Chapter 15: Code Review](15-code-review.md) for testing best practices.
+
+### Third-Party Agents on GitHub.com and GitHub Cloud
+
+GitHub supports assigning cloud agents to issues and pull requests. You can use Copilot Agent, Claude (by Anthropic), or OpenAI Codex for task automation at scale.
+
+**Accessibility workflow for cloud agents:**
+- Tag issues with labels that trigger agent assignments (`` `agent-review`, `documentation` ``)
+- Create a custom instruction or hook that directs agents to consider accessibility
+- Review agent PRs with Accessibility Agents before merging
+- Use `` `@compliance-mapping` `` to verify WCAG alignment of agent-generated code
+
+**GitHub cloud agent assignment syntax:**
+```
+@copilot please implement this feature with accessibility best practices in mind.
+Reference: [Appendix K: GitHub Agentic Workflows](appendix-k-copilot-reference.md#14-github-agentic-workflows-and-third-party-agents)

+For detailed information about cloud agents, third-party integrations, and platform-specific deployment, see [Appendix K: GitHub Agentic Workflows and Third-Party Agents](appendix-k-copilot-reference.md#14-github-agentic-workflows-and-third-party-agents).

 `podcasts/bundles/*.md` files are generated prompt packets. They are intentionally ignored by git and should be regenerated when needed.
 `podcasts/challenge-bundles/*.md` files are the same kind of generated prompt packet, but scoped to individual Challenge Coach episodes.
 
+Transcript generation now writes three artifacts for each episode or challenge:
+
+- the transcript source in `podcasts/scripts/`
+- the segment manifest in `podcasts/transcripts/*-segments.json`
+- the ordered chapter plan in `podcasts/transcripts/*-chapters.json`
+
+The chapter plan is sequential, not time-based. It stores chapter titles with segment indexes. Later, the metadata pass converts those ordered boundaries into timed ID3 chapter markers and Podcasting 2.0 chapter sidecars after audio generation.
+
+You can also regenerate a subset instead of rebuilding all 75 scripts:
+
+```bash
+npm run generate:podcast-transcript -- --slug ep05-working-with-issues
+npm run generate:podcast-transcript -- --start 1 --end 4 --group challenges
+npm run generate:podcast-transcript -- --start 20 --end 25 --group appendices

 - Author website: [Community Access website](http://www.community-access.org)
 - Description: episode description or challenge focus
 - Episode script: the matching `podcasts/scripts/*.txt` source embedded as both a custom text frame and an unsynchronized lyrics frame
-- Smart chapters: ID3 chapter frames derived from `podcasts/audio/segments/<episode>/manifest.json`
+- Smart chapters: ID3 chapter frames derived from `podcasts/audio/segments/<episode>/manifest.json`, preferring transcript-authored chapter plans from `podcasts/transcripts/*-chapters.json` when available
 - Chapter sidecars: Podcasting 2.0 JSON files in `podcasts/chapters/`, linked from RSS as `podcast:chapters`
 
-Chapter markers are pause-aware. The tool starts with the opening segment, prefers natural boundaries after `[PAUSE]`, avoids very short chapters, and forces a new marker when a section grows too long. Chapter titles are generated from the next spoken segment with small heuristics for questions, "big idea" openings, practice anchors, and why-it-matters sections.
+Chapter markers now have a two-stage flow:
+
+1. Transcript generation writes ordered chapter plans using segment indexes, while the lesson structure is still available.
+2. Metadata tagging converts those segment indexes into timed chapter markers after audio generation.
+
+If no transcript-authored chapter plan exists, the metadata tool falls back to the older pause-aware heuristic. That fallback starts with the opening segment, prefers natural boundaries after `[PAUSE]`, avoids very short chapters, and forces a new marker when a section grows too long.
+
+For one-episode GPT-5.4 pilot work, see `podcasts/tools/agentic-pilot/README.md`.
+
+For a full-catalog refresh, the recommended sequence is:
+
+```bash
+npm run generate:podcast-transcripts
+npm run podcast:chapters:normalize
+npm run podcast:chapters:audit

+  "transcriptText": "[ALEX]\nWelcome back to Challenge Coach. Today we are taking on File Your First Issue, one careful step at a time.\n\n[JAMIE]\nAnd I am Jamie. I am listening for the confusing parts: where to start, what to submit, and how to tell whether it worked.\n\n[PAUSE]\n\n[ALEX]\nIn this challenge, the learner is practicing finding a TODO, creating a clear issue, and explaining what needs to change. The point is not to rush. The point is to leave a clear trace of good work.\n\n[JAMIE]\nSo we should name what success sounds like before the learner starts clicking or typing.\n\n[ALEX]\nYes. When the checkpoint is clear, the learner can tell the difference between being stuck and simply not being finished yet.\n\n[PAUSE]\n\n[JAMIE]\nWhat makes this practice feel low-stakes but still real?\n\n[ALEX]\nChallenge 2: File Your First Issue: What you will do: Find a TODO comment in docs/welcome.md, then file an issue describing the problem with a clear title and description.\n\n[ALEX]\nA solid issue habit is to read the title, the body, and the timeline before acting. You are listening for the requested action, the missing evidence, and the person who needs a response.\n\n[JAMIE]\nHow would you walk the room through that step by step?\n\n[ALEX]\nInstructions has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere are the anchors worth keeping. What needs to change. Where the problem is (file name and what section). Why it matters.\n\n[ALEX]\nStart here: Open docs/welcome.md and look for a line that contains TODO -- this marks something that needs fixing. Then: Go to the Issues tab and select New issue. Next: Write a clear, descriptive title (not just \"Fix TODO\"). Last: In the description, explain. The point is not speed; the point is never losing your place.\n\n[JAMIE]\nWhat is the one idea that makes the next few steps less mysterious?\n\n[ALEX]\nThis is the move inside What makes a good issue title?: I found a TODO in docs/welcome.md that said.\n\n[JAMIE]\nThat feels much more doable when you say it as one move.\n\n[ALEX]\nRight. The magic is not speed. The magic is knowing what changed and why it matters.\n\n[PAUSE]\n\n[ALEX]\nNow bring the learner back to the room. Anchor this part on Peer simulation check. Open the Peer Simulation: Welcome Link Needs Context issue and leave a comment: Is the title clear? This is the part to say slowly: Would you know what needs fixing just from reading the title?\n\n[JAMIE]\nWhat would you say to someone who is already bracing for this to be too much?\n\n[ALEX]\nThe reason this matters is simple: in docs/welcome.md, line 15, there is a TODO comment that says \"add link to workshop schedule.\" This placeholder should be replaced with an actual link so students can find the schedule.\n\n[ALEX]\nThe useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.\n\n[ALEX]\nThat matters because of the next idea. Do not treat Example 2: Feature request style as decoration. The welcome document covers what students will do but does not mention accessibility features. That is not trivia. A short section pointing students to screen reader shortcuts and keyboard navigation would help everyone start on equal footing. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[PAUSE]\n\n[JAMIE]\nOkay, set the room for us. What are we walking into?\n\n[ALEX]\nWhat makes a good issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is what that changes in practice. Clear title: Someone scanning the issue list can understand the topic without opening it. Enough context: Another person could find and understand the problem from your description alone. Reproducible location: File name and line number (if relevant) so the fix is easy to find.\n\n[ALEX]\nThis is where the talk moves from concept to action. Put Alternate approaches into plain language. Both bug reports and feature suggestions are valid for this challenge. The useful version is: The key is writing clearly enough that a stranger could act on your issue.\n\n[JAMIE]\nNow it sounds like a workflow instead of a wall of instructions.\n\n[ALEX]\nThat is where confidence comes from: not from never getting lost, but from knowing how to recover.\n\n[ALEX]\nA solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.\n\n[JAMIE]\nWhere do you want a learner to place their attention here?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. Issues are where open source collaboration begins. That is the difference between guessing and knowing: everything from finding the right issue to file a perfect bug report - all with your keyboard and screen reader.\n\n[PAUSE]\n\n[ALEX]\nBefore the learner moves on. This part earns its place because chapter 5 is the first issue-based challenge chapter with short, confidence-building tasks. That gives the learner a foothold: it supports Challenge 2 (File Your First Issue) and Challenge 3 (Join the Conversation). That is the difference between following directions and owning the workflow.\n\n[ALEX]\nThat becomes easier when you listen for these cues. There are 2 core challenges plus one optional extension. Each challenge should take under 10 minutes. The evidence is issue comments and issue metadata. The pattern is claim - act - confirm.\n\n[JAMIE]\nGive me the sequence, because order matters here.\n\n[ALEX]\nChapter 5 Challenge Set: Chapter 5 focuses on issue skills. The next useful detail is concrete: You do NOT need to create a branch or edit any files for these challenges.\n\n[ALEX]\nFirst, create your first issue - file a new issue with a clear title and description. Then, comment and @mention - leave a comment on a classmate's issue and tag them with an @mention. After that, optional extension: Add a sub-issue - break a larger issue into smaller, trackable pieces if your repository has sub-issues enabled. Each step should leave a trace you can name.\n\n[JAMIE]\nWhat does the learner do first, second, and then after that?\n\n[ALEX]\nHere is the learner-facing version. File a new issue in your Learning Room repository with a specific title and a meaningful description. Put another way, issues are the prompts that wake up AI.\n\n[ALEX]\nHere is the part that makes the next action easier. \"Agent Request: Add missing contributor background paragraph in welcome.md\". \"Keyboard shortcuts table has incorrect NVDA modifier key\". \"Setup guide link to accessibility settings is broken\". What the problem is or what content is missing.\n\n[ALEX]\nStart here: Open your Learning Room repository in your browser. Then: Navigate to the Issues tab (press G then I to jump there with keyboard shortcuts, or find the \"Issues\" link in the repository navigation). Next: Activate the New issue button. Last: If a template picker appears, select Open a blank issue (or choose a template if one fits). If one step does not match what you hear, stop there and re-orient.\n\n[JAMIE]\nTurn that into a path someone can follow.\n\n[ALEX]\nWalk it in order: In the Title field, type a clear, specific title (at least 12 characters); In the Body field, write a meaningful description (at least 80 characters); Activate Submit new issue; and Copy the issue URL or note the issue number (for example, 150). You will reference this later. That is the rhythm: orient, act, verify, continue.\n\n[PAUSE]\n\n[JAMIE]\nWhat is the ordered workflow?\n\n[ALEX]\nThis is the move inside Challenge 3 Step-by-Step: Comment and @Mention: leave a comment on another student's issue and use an @mention to notify them. That matters in practice: the Issues tab of your Learning Room repository on GitHub.com.\n\n[ALEX]\nThese are the pieces that turn the idea into a usable move. \"@classmate I can confirm this - the link in setup-guide.md goes to a 404 page.\". \"@classmate Good catch! I think the correct shortcut is Insert+F7, not Insert+F5.\". \"@classmate I'd suggest adding the paragraph right after the 'Who Can Contribute' heading.\".\n\n[ALEX]\nWalk it in order: Open the Issues tab in your Learning Room repository; Find an issue created by a classmate (look for recent open issues, or use a facilitator-provided peer-simulation issue); Open the issue by activating its title link; and Read the issue description to understand what they reported. That is the rhythm: orient, act, verify, continue.\n\n[JAMIE]\nLet's pause on Challenge 3 Step-by-Step: Comment and @Mention. What should a learner take away from it?\n\n[ALEX]\nThink of this as 3 checks: Scroll to the comment box at the bottom of the issue; Write a helpful comment that @mentions the issue author by username; and Activate the Comment button (or press Ctrl+Enter). That small check between steps is what makes the workflow reliable.\n\n[JAMIE]\nThat is the kind of detail that keeps a screen reader user oriented.\n\n[ALEX]\nYes. The named thing - the heading, tab, field, branch, or button - is the handhold.\n\n[JAMIE]\nLet's pause on Optional Extension Step-by-Step: Add a Sub-Issue. What should a learner take away from it?\n\n[ALEX]\nAnchor this part on Optional Extension Step-by-Step: Add a Sub-Issue. Break a larger issue into smaller, trackable pieces using GitHub's sub-issue feature. This is the part to say slowly: the issue you created in Challenge 2 (or any open issue you have permission to edit). The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[ALEX]\nListen for the small confirmations in this list. Sub-issue: \"Add alt text to welcome banner image\". Sub-issue: \"Fix heading hierarchy in Getting Started section\".\n\n[ALEX]\nThink of this as 4 checks: Open the issue you created in Challenge 2; Look for the Sub-issues section in the issue sidebar (right side on desktop). If you do not see it, look for an Add sub-issue button or the Create sub-issue option below the issue description; Activate Add sub-issue and choose Create new sub-issue; and Give the sub-issue a clear title that describes one specific piece of the parent issue. For example, if the parent is \"Fix accessibility in welcome.md\". That small check between steps is what makes the workflow reliable.\n\n[JAMIE]\nBefore we leave Optional Extension Step-by-Step: Add a Sub-Issue, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is add a short description and activate Create. Step two is the sub-issue now appears nested under the parent issue with a progress indicator. The sequence works because every action has a confirmation.\n\n[JAMIE]\nWhat should the learner prove to themselves after each small task?\n\n[ALEX]\nThe reason this matters is simple: when you have finished the Chapter 5 issue challenges, go to your assigned Challenge 2 or Challenge 3 issue and post a comment with your evidence. The listener should be able to check this: Replace [number] with the actual issue numbers.\n\n[PAUSE]\n\n[ALEX]\nThe next point gives the learner a handle. Expected Outcomes has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThis is where the lesson becomes something you can check. Student can create an issue with a clear title and description. Student can communicate in issue threads using @mentions. Student can organize work by breaking issues into sub-issues.\n\n[JAMIE]\nLet's pause on If You Get Stuck. What should a learner take away from it?\n\n[ALEX]\nIf You Get Stuck has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nStart here: Can't find a classmate's issue? Filter the Issues tab by is:open and look for recent ones. Then: @mention not working? Make sure you type @ immediately followed by the username with no space. Next: Sub-issue option not visible? Ask a facilitator - the feature may need to be enabled for the repository. Last: Still stuck? Ask a facilitator for a direct issue link. Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave If You Get Stuck, what is the practical point?\n\n[ALEX]\nWalk it in order: Finished but not sure you did it right? Compare your work against the Challenge 2 reference solution or the Challenge 3 reference solution. The point is not speed; the point is never losing your place.\n\n[ALEX]\nHold that next to this. Put Learning Moment into plain language. Issues are collaborative spaces, not just task lists. The useful version is: An @mention tells someone \"I need your attention here.\" Sub-issues turn vague tasks into clear checklists. The interface gets easier when it becomes a set of named places instead of a wall of controls.\n\n[JAMIE]\nSo the learner is not behind if they stop there and check the page.\n\n[ALEX]\nYes. Pausing to verify is not a detour; it is how you keep control of the workflow.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Learning Pattern Used in This Chapter. What should a learner take away from it?\n\n[ALEX]\nLearning Pattern Used in This Chapter has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThink of this as 4 checks: Start with a small, safe action (create an issue); Practice communication in public issue threads (@mention a peer); Organize work into smaller pieces (sub-issues); and Leave clear evidence in the issue timeline. Each step should leave a trace you can name.\n\n[JAMIE]\nBefore we leave Learning Pattern Used in This Chapter, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is build momentum for file editing and PR work in Chapter 6. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nThat connects to another useful point. This part earns its place because this chapter provides learning cards: expandable blocks that offer perspective-specific guidance for different ways of working. That gives the learner a foothold: not every card appears at every step.\n\n[JAMIE]\nWhat should they understand before typing anything?\n\n[ALEX]\nLocal Git Alternative: Working from Your Clone: If you cloned the learning-room in Block 0 and prefer working locally. The next useful detail is concrete: During Block 0 you cloned the Learning Room repository to your computer.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like cd /Documents/learning-room or wherever you cloned it; git status should show \"On branch main\". List your assigned challenge issues; gh issue list --assignee @me --label challenge; View a specific issue in the terminal; gh issue view 42; Leave a comment on an issue; gh issue comment 42 --body \"I'd like to try this!\"; Create a new issue interactively; gh. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[ALEX]\nA solid Git habit is to know which branch you are on, what changed, and what confirmation you expect before you run the next command.\n\n[PAUSE]\n\n[ALEX]\nHere is the practical turn. Here is the learner-facing version. An issue is a discussion thread attached to a repository. Put another way, every issue has a number ( 42), a state (Open or Closed), a title, a description, and a comment thread. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[ALEX]\nOn the ground, that means a few things. Bug reports - \"This feature doesn't work when using a screen reader\". Feature requests - \"It would help if the submit button had an accessible label\". Questions - \"How do I configure X for Y use case?\". Tasks - \"Update the README with screen reader instructions\".\n\n[JAMIE]\nLet's pause on From a repository page. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside From a repository page: click the Issues tab in the repository navigation bar below the repository name. That matters in practice: The tab shows the open issue count (e.g., \"Issues · 14\").\n\n[ALEX]\nWalk it in order: Press D to navigate to the \"Repository navigation\" landmark; Press K or Tab to move through the tab links; Find \"Issues\" - it will be announced with the count: \"Issues, 14 open\"; and Press Enter to open the Issues tab. The sequence works because every action has a confirmation.\n\n[JAMIE]\nBefore we leave From a repository page, what is the practical point?\n\n[ALEX]\nThink of this as 4 checks: VO+U → Landmarks → navigate to \"Repository navigation\"; VO+Right or Quick Nav K to move through tab links; Find \"Issues\" - VoiceOver announces the count: \"Issues 14\"; and VO+Space to activate the Issues tab. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like gh issue list. gh issue list --label \"good first issue\"; gh issue list --assignee @me; gh issue list --state closed. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nThat is a useful checkpoint before anyone starts pressing keys.\n\n[ALEX]\nExactly. Checkpoints turn uncertainty into information.\n\n[ALEX]\nKeep the thread going. Anchor this part on Direct URL. Navigate directly: https://github.com/[owner]/[repo]/issues.\n\n[PAUSE]\n\n[JAMIE]\nIf I am listening before the workshop starts, what should settle in my mind first?\n\n[ALEX]\nLearning Cards: Navigating to the Issues List has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThese are the details that keep the idea from floating away. Press D to jump to the \"Repository navigation\" landmark, then K or Tab to find the Issues link -- this is faster than arrowing through the entire page. The Issues tab announces its open count (\"Issues, 14 open\"), giving you an instant sense of project activity without loading the list. Use gh issue list in the terminal to bypass browser navigation entirely; pipe through --label or --assignee @me to pre-filter results. The Issues tab count badge may be small at default zoom; at 200%+ the tab text reflows but the count remains visible next to the word \"Issues\". Bookmark the direct URL pattern (github.com/owner/repo/issues) to skip repository page navigation altogether. In high-contrast mode, the active tab is indicated with an underline using system highlight color, not just a subtle background change.\n\n[ALEX]\nAnother way to ground it. Do not treat Page structure as decoration. Quick orientation tip: Press NVDA+F7 (or VO+U on macOS) to open a list of all headings, links, form fields, and buttons on the page. That is not trivia. This is often faster than tabbing through many elements and helps you understand the full page structure before diving in. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[JAMIE]\nLet's pause on How to read the issue list. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, How to read the issue list is still useful because the issues list shows each issue as a row with its title, labels, number, assignee avatars, and comment count. For someone navigating by keyboard or screen reader, this detail matters: Closed issues show a purple merged/closed badge.\n\n[ALEX]\nIf someone is taking notes, this is the short list. Issue titles are the largest text in each row and remain readable at 200%+ zoom. Label badges use colored backgrounds with text inside. In Windows High Contrast mode, labels display with system border colors and readable text rather than colored backgrounds. The Open and Closed toggle links above the list let you switch views. The active toggle is bold or underlined. The comment count icon (a speech bubble) may be small at high zoom. It appears to the right of each issue row. Hover to see \"N comments\" tooltip.\n\n[ALEX]\nStart here: Press D to reach the \"Search Results List\" landmark. Then: Press 3 (h3) to navigate by issue titles - each issue title is an h3 link. Next: Press I to move between list items if you want more detail per item. Last: Press Enter on a title to open that issue. Each step should leave a trace you can name.\n\n[JAMIE]\nBefore we leave How to read the issue list, what is the practical point?\n\n[ALEX]\nWalk it in order: VO+U → Landmarks → navigate to \"Search Results List\"; VO+Down to read through items; and H (with Quick Nav on) or VO+U → Headings to jump by issue title. If one step does not match what you hear, stop there and re-orient.\n\n[PAUSE]\n\n[ALEX]\nThis is the part worth saying out loud. Put What is announced per issue into plain language. When you navigate to an issue in the list, your screen reader will announce (in some order).\n\n[ALEX]\nThe useful version is not abstract; it sounds like this. Issue title (as a link). Issue number ( 42). Labels (e.g., \"bug, good first issue\"). Who opened it and when (\"Opened 3 days ago by username\"). Number of comments (\"5 comments\").\n\n[JAMIE]\nI like that because it gives people permission to slow down.\n\n[ALEX]\nThat is the goal. We want the page to feel explorable, not fragile.\n\n[JAMIE]\nGive me the version that sounds like an instructor, not a manual.\n\n[ALEX]\nLearning Cards: The Issues List Page has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nA few details make that real. Press D to jump to the \"Search Results List\" landmark, then press 3 to navigate issue titles (each is an H3 link). Press I to move between individual list items if you want full detail per issue (number, labels, author, age). After applying a filter, the issue list updates silently; press 3 again to re-navigate the updated list from the top. Issue titles are the largest text per row and stay readable at 200%+ zoom; labels appear as small colored badges to the right of each title. The Open/Closed toggle links are near the top of the list; the active state is bold or underlined depending on your theme. If the comment count icon (speech bubble) is too small at your zoom level, hover over it for a tooltip showing the exact count.\n\n[ALEX]\nPut that beside the next piece. This part earns its place because filtering lets you narrow the list to find the right issue quickly. That is the difference between following directions and owning the workflow.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Using the search/filter bar. What should a learner take away from it?\n\n[ALEX]\nUsing the search/filter bar has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nFirst, press F or E to jump to the filter input field (or navigate from the landmark). Then, switch to Focus Mode (NVDA+Space / Insert+Z) if not already in it. After that, type your filter or search query. Finally, press Enter to apply. The sequence works because every action has a confirmation.\n\n[JAMIE]\nLet's pause on Using the filter buttons. What should a learner take away from it?\n\n[ALEX]\nHere is the learner-facing version. Above the issue list, there is an actions toolbar with filter buttons for Labels, Milestones, Assignees, etc. Put another way, the filter buttons do not indicate the current filter state.\n\n[ALEX]\nThat shows up in the workshop in a few specific ways. The Label, Milestone, and Assignee buttons may wrap to a second row. Each button opens a dropdown with searchable options. Dropdown menus from filter buttons can extend below the visible viewport at high zoom. Scroll within the dropdown to see all options. Type in the search field at the top of each dropdown to narrow the list (for example, type \"accessibility\" in the Label dropdown). In Windows High Contrast mode, the selected filter values are indicated with a checkmark icon and system highlight color, not just a background color change.\n\n[ALEX]\nStart here: Press Tab from the search bar (or Shift+Tab from the issue list) to reach the actions toolbar. Then: Press ←/→ to move between toolbar options (Label, Milestone, Assignee, Sort). Next: Press Enter to open the selected dropdown. Last: Use ↑/↓ to navigate options in the dropdown. Keep it that plain: know where you are, make the move, check the result.\n\n[JAMIE]\nBefore we leave Using the filter buttons, what is the practical point?\n\n[ALEX]\nWalk it in order: Press Enter or Space to select; Press Escape to close (filter applies immediately); Tab forward from the search bar to reach the filter buttons, or use Quick Nav to find them; and VO+Left/Right to move between Label, Milestone, Assignee, Sort buttons. Pause after each step and listen for the confirmation before moving on.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Filter by label; gh issue list --label \"accessibility\"; Combine filters; gh issue list --label \"good first issue\" --assignee @me; Filter by milestone; gh issue list --milestone \"Hackathon Day 1\"; Search with keywords; gh issue list --search \"screen reader\". Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Open vs Closed filter. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside Open vs Closed filter: the two state links \"Open\" and \"Closed\" appear near the top of the issue list. That matters in practice: Press K to navigate links until you find them, or look for them as buttons near the search bar.\n\n[JAMIE]\nThat is the part I would want someone to say out loud while they work.\n\n[ALEX]\nExactly. A learner should always know what they are trying to prove before they take the next action.\n\n[PAUSE]\n\n[ALEX]\nThis is where confidence starts to build. Learning Cards: Filtering and Searching Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nFor a learner, the useful signals are concrete. Switch to Focus Mode (NVDA+Space) before typing in the filter bar; switch back to Browse Mode after pressing Enter to read the filtered results. The filter bar does not announce how many results remain after filtering; press H to jump to the issue list heading, then listen for the count in the heading text. Combine gh issue list flags (e.g., --label \"accessibility\" --assignee @me) for instant filtered results without navigating dropdown menus. Filter dropdown menus can extend below the viewport at high zoom; scroll within the dropdown or type in the search field at the top of each dropdown to narrow options. After applying a filter, verify it took effect by checking the search bar text -- it updates to show active conditions like is:open label:accessibility. The Ctrl+/ (Windows) or Cmd+/ (Mac) shortcut focuses the search bar instantly, avoiding the need to scroll up to find it.\n\n[JAMIE]\nLet's pause on Landing on an issue page. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: when you open an issue, the page structure is.\n\n[JAMIE]\nLet's pause on Reading the issue description. What should a learner take away from it?\n\n[ALEX]\nDo not treat Reading the issue description as decoration. Browse Mode recommended: The issue detail page is primarily text-based. That is not trivia. Stay in Browse Mode (not Focus Mode) for reading - it gives you full heading (H), section (D), and link (K) navigation throughout the page.\n\n[ALEX]\nFirst, press 2 to reach the \"Description\" heading. Then, press ↓ to read the content line by line,. After that, use NVDA+↓ (NVDA say all) to have it read continuously. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like View issue in terminal (renders Markdown); gh issue view 42; Open the issue in your browser instead; gh issue view 42 --web; View just the comments; gh issue view 42 --comments. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Reading comments and activity. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, Reading comments and activity is still useful because each comment in the thread is marked as an h3. For someone navigating by keyboard or screen reader, this detail matters: Other timeline events (label added, PR linked, issue closed) appear between comments in the activity stream.\n\n[ALEX]\nThe parts worth keeping in working memory are these. Commenter's username. Timestamp (\"2 days ago\"). Body text. Reactions (if any - announced as a button with an emoji and count).\n\n[ALEX]\nNow slow down for the part people usually miss. Learning Cards: Reading an Issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThe room should hear these as checkpoints. Press 1 to hear the issue title, then 2 to reach \"Description\" and \"Activity\" headings, and 3 to jump between individual comments. Stay in Browse Mode for reading; only switch to Focus Mode (NVDA+Space) when you need to type in the comment box. Press D to jump to the \"Add a comment\" landmark at the bottom of the page to skip directly to the reply area. The issue title is the largest text on the page, followed by an Open/Closed badge in green or purple. Comment blocks have a subtle border and a grey header bar showing the author's avatar and timestamp; zoom in on the header to identify commenters. The sidebar (Labels, Assignees, Milestone) is on the right at desktop width; at high zoom it may move below the main content.\n\n[JAMIE]\nSo this is less about memorizing and more about noticing.\n\n[ALEX]\nRight. Once the learner can name the move, the interface becomes much less intimidating.\n\n[JAMIE]\nLet's pause on Step-by-step. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. To close the issue while commenting: click the arrow on the Close issue button and choose Close with comment. That is the difference between guessing and knowing: Low vision users (zoom, high contrast).\n\n[ALEX]\nThink of this as 4 checks: Scroll to the bottom of the issue page; Click in the Leave a comment text area; Type your comment (Markdown is supported - use the toolbar buttons above the text for bold, italic, code, etc.); and Optionally click Preview to see how it will render. The sequence works because every action has a confirmation.\n\n[JAMIE]\nBefore we leave Step-by-step, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is click the green Comment button to post. Step two is scroll to the bottom to find the Leave a comment text area. At 200%+ zoom, this may require significant scrolling past the timeline. Step three is the text area expands as you type. The formatting toolbar above it (bold, italic, code, etc.) wraps at high zoom but remains functional. Step four is the Preview tab next to Write lets you check Markdown rendering before posting. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Interactive: opens your default editor ($EDITOR) to write the comment; gh issue comment 42; Inline: provide the comment text directly; gh issue comment 42 --body \"Thanks for reporting this. I can reproduce the issue with NVDA + Chrome.\". Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[ALEX]\nHere is the moment where the page starts to make sense. This part earns its place because these keyboard shortcuts work inside the text area (Focus Mode).\n\n[JAMIE]\nLet's pause on GitHub shortcuts for the Issues pages. What should a learner take away from it?\n\n[ALEX]\nGitHub shortcuts for the Issues pages: These are the GitHub built-in shortcuts for working with issues. The next useful detail is concrete: Enable Focus Mode first (NVDA: NVDA+Space, JAWS: Insert+Z) before using single-key shortcuts.\n\n[ALEX]\nNow shift from knowing the term to using it. Here is the learner-facing version. Shortcut note: For G I, press G, release it, then press I (two sequential key presses, not simultaneous). A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on On an open issue. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside On an open issue: r to quote is a power move: Select any text in a comment while in Browse Mode (Shift+Arrow to select), then press R. That matters in practice: GitHub puts the quoted text in the comment box as a Markdown blockquote.\n\n[ALEX]\nWalk it in order: Navigate to your comment (3 to jump to comments); Find the \".\" (ellipsis) menu button near your comment; Press Enter on \"Edit\" from that menu; and The comment turns into a text area - switch to Focus Mode. Each step should leave a trace you can name.\n\n[JAMIE]\nBefore we leave On an open issue, what is the practical point?\n\n[ALEX]\nThink of this as 2 checks: Make your changes; and Tab to \"Update comment\" button → Enter. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nThe next layer is this. Learning Cards: Leaving a Comment has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Press D to jump to the \"Add a comment\" landmark, which places focus near the text area; then Enter Focus Mode to start typing. Use Ctrl+Enter to submit your comment directly from inside the text area -- this avoids having to Tab through the formatting toolbar to find the Comment button. To quote someone's text in your reply, select the text in Browse Mode (Shift+Arrow), then press R; GitHub inserts it as a blockquote in the comment box automatically. The comment text area expands as you type and is full-width at high zoom, making it easy to target; use Ctrl+Enter to submit without hunting for the Comment button. Use the Preview tab next to Write to check your Markdown formatting in rendered form before posting; bold, code blocks, and links are much easier to proofread there. Keyboard formatting shortcuts (Ctrl+B for bold, Ctrl+E for inline code) work inside the text area and save time over clicking small toolbar icons.\n\n[JAMIE]\nLet's pause on Navigating to New Issue. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: from the Issues list page, click the green New issue button in the top-right of the issue list. The listener should be able to check this: If the repository has templates, a template picker page appears - click Get started next to the template that fits your needs, or click Open a blank issue to skip templates.\n\n[ALEX]\nHere is the part to remember. At 200%+ zoom, the button may move below the search bar or wrap to its own line. It remains a prominent green button. If the repository has issue templates, a template picker page appears with each template as a card. Template descriptions may truncate at high zoom. Hover over a truncated description for the full text. The Get started button next to each template is small but uses standard link styling. Press Tab to move between templates and their Get started buttons. Open a blank issue link appears at the bottom of the template list. At high zoom, scroll down to find it.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is press K to navigate links and find the \"New issue\" button/link. Step two is press Enter. Step three is if a template picker appears: press 3 to navigate template names, read the description below each, then press Enter on \"Get started\" for the right template - or find \"Open a blank issue.\" link if no template fits. Step four is quick Nav B or VO+U → Buttons to find the \"New issue\" button. That is the rhythm: orient, act, verify, continue.\n\n[JAMIE]\nBefore we leave Navigating to New Issue, what is the practical point?\n\n[ALEX]\nFirst, vO+Space to activate it. Then, if a template picker appears: Quick Nav H or VO+Cmd+H to navigate template names, then VO+Space on \"Get started\" for the right template - or Quick Nav K to find the \"Open a blank issue\" link. That small check between steps is what makes the workflow reliable.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Do not treat Filling Out the Issue Form as decoration. The issue form has these fields (order may vary depending on the template). The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[JAMIE]\nLet's pause on Title field. What should a learner take away from it?\n\n[ALEX]\nTitle field has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nStart here: Find the Title input field (F or by landmark). Then: Focus Mode → type a clear, specific title. Next: Good title: \"Screen reader announces wrong element count on Issues list with 50+ items\". Last: Bad title: \"Bug with screen reader\". The sequence works because every action has a confirmation.\n\n[JAMIE]\nLet's pause on Description / Body field. What should a learner take away from it?\n\n[ALEX]\nDescription / Body field has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nWalk it in order: Tab to the body text area; Focus Mode → type using the Markdown template provided; and If no template, use this structure. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like What happened; Describe what you observed.; What I expected; Describe what should have happened.; How to reproduce; 1. Step one; 2. Step two; 3. Step three; Environment; - Screen reader: [NVDA 2025.3.3 / JAWS 2026 / VoiceOver macOS Sonoma]; - Browser: [Chrome. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Assigning labels from the sidebar. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. See also: Chapter 09: Labels, Milestones, and Projects covers the full label and milestone system. That is the difference between guessing and knowing: While the form is open, the sidebar has dropdowns for Labels, Assignees, and Milestone.\n\n[ALEX]\nThink of this as 4 checks: Tab away from the text area (or press Escape to leave Focus Mode); Navigate to the sidebar - press H to find \"Labels\" heading; Press Enter on the Labels gear/button; and Dropdown opens → ↑/↓ to navigate labels. Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave Assigning labels from the sidebar, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is enter to select/deselect. Step two is escape to close (selections save automatically). Step three is vO+Shift+Up to stop interacting with the text area. Step four is vO+U → Headings to find the \"Labels\" heading in the sidebar. The point is not speed; the point is never losing your place.\n\n[ALEX]\nA solid project habit is to treat metadata as decision support. Labels, status, assignees, and notifications tell you what kind of attention the work needs.\n\n[JAMIE]\nLet's pause on Submitting the issue. What should a learner take away from it?\n\n[ALEX]\nThis part earns its place because GitHub CLI (gh) alternative - filing a new issue. That gives the learner a foothold: create an issue from your terminal. That is the difference between following directions and owning the workflow.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is tab to \"Submit new issue\" button. Step two is press Enter. The point is not speed; the point is never losing your place.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Interactive: prompts for title, body, labels, and assignees; gh issue create; Inline: provide everything on the command line; gh issue create --title \"Screen reader announces wrong count on Issues list\" \\; --body \" What happened\\n\\nThe count says 14 but only. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Learning Cards: Filing a New Issue. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Filing a New Issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. After pressing \"New issue,\" if a template picker appears, press 3 to jump between template names; each has a \"Get started\" link next to it. In the title field, type at least 12 characters for a meaningful title; press Tab to move to the body field. Press Ctrl+Enter from inside the body text area to submit the issue without needing to find the Submit button. The green \"New issue\" button is in the top-right of the Issues list page; at 200%+ zoom it may wrap below the search bar. Template cards (if the repo uses them) show truncated descriptions at high zoom; hover over them for the full text. The sidebar dropdowns for Labels, Assignees, and Milestone are gear icons that may be small at high zoom; they open searchable dropdown panels.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Tool Cards: File a New Issue. What should a learner take away from it?\n\n[ALEX]\nHere is the learner-facing version. github.dev (web editor): Not available -- issues are managed through the repository's Issues tab, not the code editor. Put another way, VS Code Desktop (GitHub Pull Requests extension).\n\n[ALEX]\nStart here: Navigate to the repository's Issues tab (or press G then I). Then: Click New issue, choose a template or blank issue. Next: Fill in the title and description, then click Submit new issue. Last: Open the GitHub panel in the sidebar. If one step does not match what you hear, stop there and re-orient.\n\n[JAMIE]\nBefore we leave Tool Cards: File a New Issue, what is the practical point?\n\n[ALEX]\nWalk it in order: Under Issues, click the + icon to create a new issue; and Fill in the title and body, then click Create. That is the rhythm: orient, act, verify, continue.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like gh issue create --title \"Your title\" --body \"Description here\"; Or interactively:; gh issue create. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Cross-Referencing Issues. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside Cross-Referencing Issues: linking issues and PRs to each other creates a trail of context that helps everyone understand the project's history.\n\n[ALEX]\nKeep the teaching thread moving. Anchor this part on Closing keywords in PR descriptions or issue comments. When you type these phrases in a PR description or comment (followed by an issue number), GitHub creates a connection. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Mentioning another issue in a comment. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: simply type followed by a number anywhere in a comment body. The listener should be able to check this: GitHub autocompletes with a dropdown of matching issues and PRs.\n\n[ALEX]\nKeep the teaching thread moving. Do not treat Cross-repo references as decoration. owner/repo 42 - references issue 42 in a different repository.\n\n[JAMIE]\nLet's pause on Learning Cards: Cross-Referencing Issues. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Cross-Referencing Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Type in any comment body to trigger GitHub's autocomplete dropdown; press Down Arrow to browse matching issues and Enter to insert the reference link. Use Closes 42 (not just 42) in PR descriptions so GitHub automatically closes the issue on merge; your screen reader will confirm the link is created in the PR timeline. Cross-references appear as timeline events on the linked issue; navigate with H to find \"mentioned this issue\" entries to trace the conversation history. Cross-reference links ( 42) render as colored, clickable links in both issue bodies and PR descriptions; at high zoom they remain inline with surrounding text. The autocomplete dropdown triggered by may overlap content at high magnification; type additional digits to narrow results and reduce dropdown size. Back-links appear automatically on the referenced issue's timeline, so you can verify the connection was created by visiting either side.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Put Sub-Issues - Parent and Child Relationships into plain language. Sub-issues (released 2025) let you nest issues inside a parent issue to break large work into tracked pieces. The useful version is: A \"parent\" issue contains a list of child issues; each child is a full issue with its own discussion, labels, and assignees. The interface gets easier when it becomes a set of named places instead of a wall of controls.\n\n[JAMIE]\nCan you translate that into plain choices?\n\n[ALEX]\nWhen to Use Sub-Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nUse the comparison to make a decision, not to recite a table. The main contrasts are: Large feature broken down means Parent: \"Redesign navigation\"; Children: \"Keyboard nav,\" \"Screen reader nav,\" \"Mobile nav\". Epic tracking means Parent: \"WCAG 2.1 AA compliance\"; Children: one issue per failing criterion. Release milestone means Parent: \"v2.0 release\"; Children: every required PR/fix.\n\n[ALEX]\nKeep the teaching thread moving. This part earns its place because the sub-issues section is announced as a region. That gives the learner a foothold: after linking, the child issue appears as a list item with a checkbox showing its open/closed state.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Reading Sub-Issues on a Parent Issue. What should a learner take away from it?\n\n[ALEX]\nReading Sub-Issues on a Parent Issue: Progress indicator: The parent issue shows a completion bar (e.g., \"3 of 7 completed\") based on how many child issues are closed. The next useful detail is concrete: Screen readers announce this as a progress region.\n\n[ALEX]\nKeep the teaching thread moving. Here is the learner-facing version. Every child issue shows a \"Parent issue\" link near the top of the page (above the description). Put another way, navigate with H or links (K) to find it. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[JAMIE]\nLet's pause on Sub-Issues vs. Task Lists. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside Sub-Issues vs. Task Lists: if you are working on a feature that requires multiple PRs or involves several team members, ask the maintainer to create a parent issue. That matters in practice: You can then claim individual child issues without one person owning the whole feature.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Learning Cards: Sub-Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. The sub-issues section is announced as a region; press H to navigate to the \"Sub-issues\" heading, then arrow down through the list where each child announces its checkbox state, title, and open/closed badge. The parent issue shows a progress indicator (\"3 of 7 completed\") announced as a progress region; listen for this after the sub-issues heading to gauge overall status. Every child issue includes a \"Parent issue\" link near the top of its page; navigate with K (links) to find it and jump back to the parent quickly. The completion progress bar on the parent issue uses color to show progress; in high-contrast mode, completed vs. remaining segments use distinct system colors. At high zoom, the \"Add sub-issue\" button may wrap below the sub-issues list; Tab past the last child item to reach it. Each child issue's open/closed badge uses both color and text (\"Open\" or \"Closed\"), so status is readable without relying on color alone.\n\n[JAMIE]\nLet's pause on Closing an issue. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: scroll to the bottom of the issue page. The listener should be able to check this: Click the Close issue button next to the comment box.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is keyboard shortcut (fastest): Navigate to the comment text area (D → \"Add a comment\" landmark), switch to Focus Mode, then press Ctrl+Shift+Enter to close the issue. Step two is button approach: Tab to the \"Close issue\" button (at the bottom of the page, near the comment box) and press Enter. Step three is optionally leave a closing comment first. Step four is keyboard shortcut (fastest): VO+U → Landmarks → \"Add a comment\", interact with the text area (VO+Shift+Down), then press Cmd+Shift+Return to close the issue. Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave Closing an issue, what is the practical point?\n\n[ALEX]\nFirst, button approach: Quick Nav B or Tab to find the \"Close issue\" button, then VO+Space. The point is not speed; the point is never losing your place.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Close an issue; gh issue close 42; Close with a reason; gh issue close 42 --reason \"completed\"; gh issue close 42 --reason \"not planned\"; Close with a comment; gh issue close 42 --comment \"Fixed in PR 45.\"; Reopen a closed issue; gh issue reopen 42. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[ALEX]\nKeep the teaching thread moving. Do not treat Reopening a closed issue as decoration. If an issue is Closed, the \"Close issue\" button becomes \"Reopen issue\" - navigate and activate to reopen. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Assigning an issue. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, Assigning an issue is still useful because GitHub CLI (gh) alternative - assigning and labeling. For someone navigating by keyboard or screen reader, this detail matters: Manage assignments and labels from your terminal.\n\n[ALEX]\nStart here: Navigate to \"Assignees\" heading (3 or H). Then: Activate the gear/plus button. Next: Type a username in the search field. Last: Select from the dropdown. Each step should leave a trace you can name.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Assign yourself; gh issue edit 42 --add-assignee @me; Add labels; gh issue edit 42 --add-label \"accessibility,in progress\"; Remove a label; gh issue edit 42 --remove-label \"needs triage\"; Set a milestone; gh issue edit 42 --milestone \"Hackathon Day 1\". Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Changing labels. What should a learner take away from it?\n\n[ALEX]\nChanging labels has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nWalk it in order: Navigate to \"Labels\" heading; Activate the gear button; Select/deselect labels from the dropdown; and Press Escape to save. If one step does not match what you hear, stop there and re-orient.\n\n[JAMIE]\nLet's pause on Transferring or deleting an issue. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. Available from the \".\" (ellipsis) button at the top of the issue - navigate buttons with B to find it.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Learning Cards: Managing Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Close an issue instantly with Ctrl+Shift+Enter from the comment text area (Focus Mode) -- no need to Tab to the Close button. The sidebar sections (Assignees, Labels, Milestone) each have their own heading; press H or 3 to jump between them, then activate the gear icon to open each dropdown. Use gh issue edit 42 --add-label \"accessibility\" --add-assignee @me to batch-update labels and assignments from the terminal without navigating sidebar controls. Sidebar controls (Assignees, Labels, Milestone) are narrow at default width; at high zoom they stack vertically and each dropdown opens a searchable overlay that is easier to read. The Close issue button turns green and its label changes to \"Reopen issue\" once closed; in high-contrast mode, both states use distinct system colors. Type in the search field inside each sidebar dropdown (Labels, Assignees) to filter long lists rather than scrolling through all options at high magnification.\n\n[JAMIE]\nLet's pause on The \"good first issue\" Label - Your Entry Point. What should a learner take away from it?\n\n[ALEX]\nThe \"good first issue\" Label - Your Entry Point: When looking for your first open source contribution. The next useful detail is concrete: Remember: It's respectful to ask before starting.\n\n[ALEX]\nFirst, navigate to any project's Issues tab. Then, filter by label: type is:open label:\"good first issue\" in the search. After that, read through issues until you find one in your area of interest. Finally, comment on the issue: \"Hi, I'd like to work on this. Can I be assigned?\". The sequence works because every action has a confirmation.\n\n[JAMIE]\nBefore we leave The \"good first issue\" Label - Your Entry Point, what is the practical point?\n\n[ALEX]\nStart here: Wait for a maintainer to respond and assign you before starting work. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nKeep the teaching thread moving. Learning Cards: The \"good first issue\" Label has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Use the filter query is:open label:\"good first issue\" in the search bar to jump directly to beginner-friendly issues; gh issue list --label \"good first issue\" does the same in the terminal. Before claiming an issue, read existing comments to check whether someone else has already been assigned; listen for \"assigned to\" in the sidebar metadata. When you comment to claim an issue, include a sentence about your approach so the maintainer can give early feedback before you start coding. The \"good first issue\" label renders with a distinct background color (typically light purple or teal); in high-contrast mode it uses system highlight colors with readable text. Filter results may include issues with multiple labels stacked together; at high zoom, labels wrap to a second line but remain readable. Bookmark the filtered URL (/issues?q=is:open+label:\"good first issue\") in your browser for one-click access to beginner issues across your favorite repositories.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Accessibility-Specific Issue Writing Tips. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside Accessibility-Specific Issue Writing Tips: when filing accessibility bugs, these details help maintainers reproduce and fix the problem.\n\n[ALEX]\nWalk it in order: Screen reader and version - \"NVDA 2025.3.3\" not just \"screen reader\"; OS and version - \"Windows 11 22H2\"; Browser and version - \"Chrome 124.0.6367.82\"; and GitHub interface - \"Modern experience (default since Jan 2026)\" or \"Classic experience (opted out)\". Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave Accessibility-Specific Issue Writing Tips, what is the practical point?\n\n[ALEX]\nThink of this as 4 checks: What was announced - quote the exact text your screen reader spoke; What should have been announced - describe the expected behavior; ARIA issue if known - e.g., \"The button has no accessible name\"; and Steps to reproduce - numbered, step-by-step. The point is not speed; the point is never losing your place.\n\n[ALEX]\nKeep the teaching thread moving. Example of a well-filed accessibility issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[JAMIE]\nLet's pause on Learning Cards: Accessibility-Specific Issue Writing. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Accessibility-Specific Issue Writing has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Always quote the exact text your screen reader announced in the issue body; wrap it in a fenced code block so readers know it is literal output, not your description. Include your screen reader name and version (e.g., \"NVDA 2025.3.3\") plus browser and OS; this lets maintainers reproduce with the same toolchain. Test with a second screen reader or browser if possible and note the results -- \"Also fails in JAWS 2026 with Chrome; works in VoiceOver with Safari\" dramatically narrows the debugging scope. When filing zoom or contrast bugs, state your exact zoom level and whether you use Windows High Contrast, macOS Increase Contrast, or a browser extension. Screenshots are powerful evidence; annotate them (circle the problem area, add a text callout) and always include alt text describing what the screenshot shows. Note whether the issue occurs only at certain zoom levels or viewport widths; a bug at 400% that disappears at 200% points to a CSS breakpoint problem.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Do not treat Writing Effective Issues as decoration. See also: Appendix N: Advanced Search covers search qualifiers to find existing issues before filing a new one. That is not trivia. A well-written issue saves everyone time -- the maintainer who reads it, the contributor who fixes it, and the future searcher who finds it six months later.\n\n[JAMIE]\nLet's pause on Bug Report Structure. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, Bug Report Structure is still useful because a strong bug report answers five questions. For someone navigating by keyboard or screen reader, this detail matters: Use this template every time you report something broken.\n\n[JAMIE]\nLet's pause on Feature Request Structure. What should a learner take away from it?\n\n[ALEX]\nPut Feature Request Structure into plain language. Feature requests work best when they focus on the problem before jumping to the solution. The useful version is: A feature request that starts with \"I want a dark mode toggle\" is weaker than one that starts with \"Low-vision users report eyestrain after 20 minutes because the current theme has insufficient contrast.\" The second version gives maintainers something to. The interface gets easier when it becomes a set of named places instead of a wall of controls.\n\n[ALEX]\nWalk it in order: Problem statement -- Describe the pain point. What are you trying to do, and why is it hard or impossible right now?; Proposed solution -- Your best idea for fixing the problem. Be specific enough to discuss, but hold it loosely; Alternatives considered -- Other approaches you thought about and why they fell short. This shows you have done your homework; and Who benefits -- Name the audience. \"Screen reader users navigating large repositories\" is more compelling than \"everyone.\". That small check between steps is what makes the workflow reliable.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on General Issue Writing Principles. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. These rules apply to every issue -- bugs, features, questions, and everything in between. That is the difference between guessing and knowing: If you discovered two bugs during the same session, file two separate issues.\n\n[ALEX]\nKeep the teaching thread moving. This part earns its place because I tried clicking and nothing happened. That gives the learner a foothold: the maintainer has to ask: What doesn't work?\n\n[JAMIE]\nLet's pause on Learning Cards: Writing Effective Issues. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Writing Effective Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Use fenced code blocks (triple backticks) when pasting error messages or screen reader output; your screen reader announces \"code block\" so listeners know the text is literal, not description. When writing \"Steps to Reproduce,\" type each step as a numbered Markdown list item (1., 2., etc.) so screen readers announce \"list with N items\". Type in the comment body to trigger issue autocomplete; press Down Arrow to navigate matching issues and Enter to insert a cross-reference link. Use the Preview tab (next to Write) to check your Markdown rendering before submitting; headings, bold text, and code blocks are much easier to proofread in rendered form. Screenshots with alt text are valuable evidence; add them with the image button in the formatting toolbar or drag-and-drop into the body field. Keep paragraphs short (3-4 sentences max) so the issue is scannable at high zoom without excessive scrolling.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Try It: File Your First Issue. What should a learner take away from it?\n\n[ALEX]\nHere is the learner-facing version. Time: 3 minutes What you need: Browser, signed in to GitHub. Put another way, go to the Learning Room repository and file a real issue. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[ALEX]\nStart here: Navigate to the Issues tab (press G then I in Focus Mode). Then: Find and activate the \"New issue\" button (K to links, or Tab to it). Next: In the title field, type: \"Introduce myself - [Your Name]\". Last: In the description, write 2-3 sentences: who you are, what screen reader you use, and one thing you're hoping to learn today. The point is not speed; the point is never losing your place.\n\n[JAMIE]\nBefore we leave Try It: File Your First Issue, what is the practical point?\n\n[ALEX]\nWalk it in order: Press Ctrl+Enter to submit (or Tab to the Submit button and press Enter). Each step should leave a trace you can name.\n\n[JAMIE]\nLet's pause on Learning Cards: Filing Your First Issue. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside Learning Cards: Filing Your First Issue: day 2 Amplifier - Accessibility Agents: @issue-tracker File, read, comment on, and triage real issues manually before using any agent. That matters in practice: If you have not done the triage work yourself - reading descriptions, assigning labels, identifying duplicates - you cannot evaluate whether an agent's priority scoring is correct.\n\n[ALEX]\nHere is the part to remember. After pressing Ctrl+Enter to submit, listen for the page reload; GitHub navigates to your new issue page where the title is the first heading -- press 1 to confirm it matches what you typed. Navigate the issue list with 3 (heading level 3) to jump between issue titles; this is faster than arrowing through every element on the page. If the template picker appears, use Tab and Enter to select \"Open a blank issue\"; template names are announced as link text. The \"New issue\" button is prominent and green on the Issues list page; at high zoom it remains visible near the top of the page and does not collapse into a menu.\n\n[PAUSE]\n\n[JAMIE]\nWhat is the final checkpoint?\n\n[ALEX]\nYou should be able to point to the evidence, explain the action, and describe what you would do next if this were a real open source project. If you can teach the move back, you have learned it.\n\n[JAMIE]\nAnd if they get stuck?\n\n[ALEX]\nRead the latest message, not the loudest worry. Check the issue, the branch, the pull request, the status check, or the bot comment. Then ask for help with those facts in hand. That is how professionals collaborate.\n",

Listen before reading to preview the concepts, or after to reinforce what you learned.\r\n\r\n> **Related appendices:** [Appendix N: Advanced Search](appendix-n-advanced-search.md) | [Appendix V: GitHub Mobile](appendix-v-github-mobile.md) | [Appendix B: Screen Reader Cheat Sheet](appendix-b-screen-reader-cheatsheet.md)\r\n> **Authoritative sources:** [GitHub Docs: About issues](https://docs.github.com/en/issues/tracking-your-work-with-issues/about-issues) | [GitHub Accessibility Guide: Issues](https://accessibility.github.com/documentation/guide/issues/)\r\n\r\n\r\n## Filing, Managing, and Participating in GitHub Issues\r\n\r\n> Issues are where open source collaboration begins. This guide covers everything from finding the right issue to file a perfect bug report - all with your keyboard and screen reader.\r\n>\r\n> **Official GitHub Accessibility Guide:** GitHub publishes an NVDA-focused guide for working with issues using a screen reader at [Using GitHub Issues with a Screen Reader](https://accessibility.github.com/documentation/guide/issues/). This chapter covers the same material with additional perspectives (VoiceOver, low vision, CLI) and workshop-specific challenges. Use the official guide as a companion reference.\r\n>\r\n> **Screen reader note - New Issues Experience:** This guide uses GitHub's improved Issues experience, which provides better ARIA landmark structure and live-region announcements for screen readers. This feature may already be active for your account - it has been broadly rolled out and may no longer appear as a Feature Preview toggle at all.\r\n>\r\n> **To verify:** Activate the **User Menu** button (top-right of any GitHub page) → activate **\"Feature preview\"** → scan the list for **\"New Issues Experience\"**:\r\n>\r\n> - If listed and the toggle announces **\"Pressed\"** (or **\"Disable\"**) - already enabled, no action needed\r\n> - If listed but **not Pressed** (or **\"Enable\"**) - activate the toggle to enable it\r\n> - If not listed at all - the feature has graduated to the standard interface; it is active automatically\r\n>\r\n> Full step-by-step instructions with per-screen-reader commands are in [Pre-Workshop Setup, Step 4](00-pre-workshop-setup.md#step-4---check-github-feature-preview-settings).\r\n>\r\n> **Browse vs Focus Mode (NVDA):** Toggle between modes with `NVDA+Space` (NVDA key = `Insert` or `Caps Lock`). Use **Browse Mode** (the default) for reading lists, headings, and issue content. Switch to **Focus Mode** when typing in text fields and search boxes. Use `NVDA+F7` at any time to open a list of all headings, links, form fields, buttons, and landmarks on the page - this is your orientation tool.\r\n\r\n\r\n## Workshop Recommendation (Chapter 5 / Challenges 2-3)\r\n\r\nChapter 5 is the first **issue-based challenge chapter** with short, confidence-building tasks. It supports Challenge 2 (File Your First Issue) and Challenge 3 (Join the Conversation).\r\n\r\n- **Challenge count:** 2 core challenges plus one optional extension\r\n- **Time per challenge:** under 10 minutes\r\n- **Evidence:** issue comments and issue metadata\r\n- **Pattern:** claim -> act -> confirm\r\n\r\n### Chapter 5 Challenge Set\r\n\r\n1. **Create your first issue** - file a new issue with a clear title and description.\r\n2. **Comment and @mention** - leave a comment on a classmate's issue and tag them with an @mention.\r\n3. **Optional extension: Add a sub-issue** - break a larger issue into smaller, trackable pieces if your repository has sub-issues enabled.\r\n\r\n> **Branch guidance for Chapter 5:** Chapter 5 focuses on issue skills. You do NOT need to create a branch or edit any files for these challenges. All your work happens in GitHub issue threads. File editing and branches start in Chapter 6.\r\n>\r\n> **How completion works:** When you finish the issue challenges, post evidence in your assigned challenge issues with links to the issue you created and the comment you posted. The facilitator reviews your issue activity directly. No pull request is required for Chapter 5.\r\n\r\n### Challenge 2 Step-by-Step: Create Your First Issue\r\n\r\n**Goal:** File a new issue in your Learning Room repository with a specific title and a meaningful description.\r\n\r\n> **Agentic strategy:** Issues are the prompts that wake up AI. A clear issue for a human is also a prompt for an agent. For this challenge, log an issue describing an accessibility problem or chore you wish an AI agent could fix for you.\r\n\r\n**Where you are working:** the Issues tab of your Learning Room repository on GitHub.com.\r\n\r\n1. Open your Learning Room repository in your browser.\r\n2. Navigate to the **Issues** tab (press `G` then `I` to jump there with keyboard shortcuts, or find the \"Issues\" link in the repository navigation).\r\n3. Activate the **New issue** button.\r\n4. If a template picker appears, select **Open a blank issue** (or choose a template if one fits).\r\n5. In the **Title** field, type a clear, specific title (at least 12 characters). Examples:\r\n   - \"Agent Request: Add missing contributor background paragraph in welcome.md\"\r\n   - \"Keyboard shortcuts table has incorrect NVDA modifier key\"\r\n   - \"Setup guide link to accessibility settings is broken\"\r\n6. In the **Body** field, write a meaningful description (at least 80 characters). Include:\r\n   - What the problem is or what content is missing.\r\n   - Where in the repository the problem exists (file name and section).\r\n   - What you think the fix should be.\r\n7. Activate **Submit new issue**.\r\n8. Copy the issue URL or note the issue number (for example, `#150`). You will reference this later.\r\n\r\n**You are done when:** Your new issue appears in the Issues list with your username as the author, a clear title, and a detailed description.\r\n\r\n### Challenge 3 Step-by-Step: Comment and @Mention\r\n\r\n**Goal:** Leave a comment on another student's issue and use an @mention to notify them.\r\n\r\n**Where you are working:** the Issues tab of your Learning Room repository on GitHub.com.\r\n\r\n1. Open the **Issues** tab in your Learning Room repository.\r\n2. Find an issue created by a classmate (look for recent open issues, or use a facilitator-provided peer-simulation issue).\r\n3. Open the issue by activating its title link.\r\n4. Read the issue description to understand what they reported.\r\n5. Scroll to the comment box at the bottom of the issue.\r\n6. Write a helpful comment that **@mentions the issue author by username**. Examples:\r\n   - \"@classmate I can confirm this - the link in setup-guide.md goes to a 404 page.\"\r\n   - \"@classmate Good catch! I think the correct shortcut is Insert+F7, not Insert+F5.\"\r\n   - \"@classmate I'd suggest adding the paragraph right after the 'Who Can Contribute' heading.\"\r\n7. Activate the **Comment** button (or press `Ctrl+Enter`).\r\n\r\n**Why @mentions matter:** When you type `@username`, GitHub sends that person a notification. This is how real open source teams communicate - you signal who needs to see your message. It also bridges into Chapter 10 (Notifications) where you will configure how you receive these alerts.\r\n\r\n**You are done when:** Your comment appears in the thread and includes an @mention (the username renders as a clickable link).\r\n\r\n### Optional Extension Step-by-Step: Add a Sub-Issue\r\n\r\n**Goal:** Break a larger issue into smaller, trackable pieces using GitHub's sub-issue feature.\r\n\r\n**Where you are working:** the issue you created in Challenge 2 (or any open issue you have permission to edit).\r\n\r\n> **What are sub-issues?** Sub-issues let you decompose a big task into smaller steps, each tracked independently. The parent issue shows a progress bar as sub-issues are completed. This is how teams organize real work - a single \"Fix accessibility in welcome.md\" issue might have sub-issues for each specific fix.\r\n\r\n1. Open the issue you created in Challenge 2.\r\n2. Look for the **Sub-issues** section in the issue sidebar (right side on desktop). If you do not see it, look for an **Add sub-issue** button or the **Create sub-issue** option below the issue description.\r\n3. Activate **Add sub-issue** and choose **Create new sub-issue**.\r\n4. Give the sub-issue a clear title that describes one specific piece of the parent issue. For example, if the parent is \"Fix accessibility in welcome.md\":\r\n   - Sub-issue: \"Add alt text to welcome banner image\"\r\n   - Sub-issue: \"Fix heading hierarchy in Getting Started section\"\r\n5. Add a short description and activate **Create**.\r\n6. The sub-issue now appears nested under the parent issue with a progress indicator.\r\n\r\n**You are done when:** Your parent issue shows at least one sub-issue in the Sub-issues section.\r\n\r\n### Completing Chapter 5: Submit Your Evidence\r\n\r\nWhen you have finished the Chapter 5 issue challenges, go to your **assigned Challenge 2 or Challenge 3 issue** and post a comment with your evidence:\r\n\r\n```text\r\nChapter 5 completed:\r\n- Challenge 2: Created issue #[number]\r\n- Challenge 3: Commented with @mention on issue #[number]\r\n- Optional: Added sub-issue to issue #[number]\r\n```\r\n\r\nReplace `[number]` with the actual issue numbers. Then close your assigned challenge issues. The facilitator will review your issue activity.\r\n\r\n### Expected Outcomes\r\n\r\n- Student can create an issue with a clear title and description.\r\n- Student can communicate in issue threads using @mentions.\r\n- Student can organize work by breaking issues into sub-issues.\r\n\r\n### If You Get Stuck\r\n\r\n1. Can't find a classmate's issue? Filter the Issues tab by `is:open` and look for recent ones.\r\n2. @mention not working? Make sure you type `@` immediately followed by the username with no space.\r\n3. Sub-issue option not visible? Ask a facilitator - the feature may need to be enabled for the repository.\r\n4. Still stuck? Ask a facilitator for a direct issue link.\r\n5. Finished but not sure you did it right? Compare your work against the [Challenge 2 reference solution](solutions/solution-02-first-issue.md) or the [Challenge 3 reference solution](solutions/solution-03-conversation.md).\r\n\r\n### Learning Moment\r\n\r\nIssues are collaborative spaces, not just task lists. An @mention tells someone \"I need your attention here.\" Sub-issues turn vague tasks into clear checklists. Both skills are used daily in real open source projects.\r\n\r\n### Learning Pattern Used in This Chapter\r\n\r\n1. Start with a small, safe action (create an issue).\r\n2. Practice communication in public issue threads (@mention a peer).\r\n3. Organize work into smaller pieces (sub-issues).\r\n4. Leave clear evidence in the issue timeline.\r\n5. Build momentum for file editing and PR work in Chapter 6.\r\n\r\n\r\n### About Learning Cards in This Chapter\r\n\r\nThis chapter provides learning cards: expandable blocks that offer perspective-specific guidance for different ways of working. Not every card appears at every step. Open the ones that match how you work.\r\n\r\nThe following table describes the five learning card types used in this chapter.\r\n\r\n| Card | Who it helps | What it covers |\r\n| --- | --- | --- |\r\n| Visual / mouse | Sighted users navigating with a mouse or trackpad | Click targets, visual cues, layout orientation |\r\n| Low vision | Users with magnification, zoom, or high-contrast themes | Zoom-friendly navigation, finding controls at high magnification, high contrast visibility |\r\n| NVDA / JAWS (Windows) | Screen reader users on Windows | Keystroke sequences, Focus and Browse mode, landmark navigation |\r\n| VoiceOver (macOS) | Screen reader users on macOS | VO key sequences, rotor usage, interaction model |\r\n| CLI (gh) | Terminal users on any platform | GitHub CLI commands for issue management |\r\n\r\n\r\n## Local Git Alternative: Working from Your Clone\r\n\r\n<details>\r\n<summary>If you cloned the learning-room in Block 0 and prefer working locally</summary>\r\n\r\nDuring Block 0 you cloned the Learning Room repository to your computer. If you are comfortable in a terminal, you can use the GitHub CLI (`gh`) from inside that clone for every issue operation in this chapter. This is the same workflow covered in depth in [Chapter 11: Git and Source Control](14-git-in-practice.md).\r\n\r\n**Verify your clone is ready:**\r\n\r\n```bash\r\ncd ~/Documents/learning-room   # or wherever you cloned it\r\ngit status                      # should show \"On branch main\"\r\n```\r\n\r\n**Common issue commands from your local terminal:**\r\n\r\n```bash\r\n# List your assigned challenge issues\r\ngh issue list --assignee @me --label challenge\r\n\r\n# View a specific issue in the terminal\r\ngh issue view 42\r\n\r\n# Leave a comment on an issue\r\ngh issue comment 42 --body \"I'd like to try this!\"\r\n\r\n# Create a new issue interactively\r\ngh issue create\r\n```\r\n\r\nAll of these produce the same result as the web interface. The chapter instructions work identically either way - choose whichever is more comfortable for you.\r\n\r\n</details>\r\n\r\n\r\n## What Is a GitHub Issue?\r\n\r\nAn issue is a discussion thread attached to a repository. Issues are used for:\r\n\r\n- **Bug reports** - \"This feature doesn't work when using a screen reader\"\r\n- **Feature requests** - \"It would help if the submit button had an accessible label\"\r\n- **Questions** - \"How do I configure X for Y use case?\"\r\n- **Tasks** - \"Update the README with screen reader instructions\"\r\n- **Accessibility reports** - \"The infinite scroll carousel is not keyboard accessible\"\r\n\r\nEvery issue has a **number** (`#42`), a **state** (Open or Closed), a **title**, a **description**, and a **comment thread**. Issues are public by default on public repositories.\r\n\r\n> **Learning Room connection:** In your Learning Room repo, every challenge from `docs/CHALLENGES.md` becomes an issue. For example, Challenge 1 (\"Fix Broken Link\") is filed as an issue pointing to `docs/welcome.md`, describing the broken link and linking to the challenge success criteria. When you open a PR to fix it, you reference the issue with `Closes #XX` to automatically close it on merge.\r\n\r\n\r\n## Navigating to the Issues List\r\n\r\n### From a repository page\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nClick the **Issues** tab in the repository navigation bar below the repository name. The tab shows the open issue count (e.g., “Issues · 14”).\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (NVDA / JAWS - Windows)</summary>\r\n\r\n1. Press `D` to navigate to the \"Repository navigation\" landmark\r\n2. Press `K` or `Tab` to move through the tab links\r\n3. Find \"Issues\" - it will be announced with the count: \"Issues, 14 open\"\r\n4. Press `Enter` to open the Issues tab\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (VoiceOver - macOS)</summary>\r\n\r\n1. `VO+U` → Landmarks → navigate to \"Repository navigation\"\r\n2. `VO+Right` or Quick Nav `K` to move through tab links\r\n3. Find \"Issues\" - VoiceOver announces the count: \"Issues 14\"\r\n4. `VO+Space` to activate the Issues tab\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>GitHub CLI (gh) alternative</summary>\r\n\r\nList open issues directly from your terminal:\r\n\r\n```bash\r\ngh issue list\r\n```\r\n\r\nFilter by label, assignee, or state:\r\n\r\n```bash\r\ngh issue list --label \"good first issue\"\r\ngh issue list --assignee @me\r\ngh issue list --state closed\r\n```\r\n\r\n**Setup:** Install the GitHub CLI from [cli.github.com](https://cli.github.com) and authenticate with `gh auth login`. See [Appendix D](appendix-d-git-authentication.md) for details.\r\n\r\n</details>\r\n\r\n### Direct URL\r\n\r\nNavigate directly: `https://github.com/[owner]/[repo]/issues`\r\n\r\n### Learning Cards: Navigating to the Issues List\r\n\r\n**Screen reader users:**\r\n- Press `D` to jump to the \"Repository navigation\" landmark, then `K` or `Tab` to find the Issues link -- this is faster than arrowing through the entire page\r\n- The Issues tab announces its open count (\"Issues, 14 open\"), giving you an instant sense of project activity without loading the list\r\n- Use `gh issue list` in the terminal to bypass browser navigation entirely; pipe through `--label` or `--assignee @me` to pre-filter results\r\n\r\n**Low-vision users:**\r\n- The Issues tab count badge may be small at default zoom; at 200%+ the tab text reflows but the count remains visible next to the word \"Issues\"\r\n- Bookmark the direct URL pattern (`github.com/owner/repo/issues`) to skip repository page navigation altogether\r\n- In high-contrast mode, the active tab is indicated with an underline using system highlight color, not just a subtle background change\r\n\r\n**Sighted users:**\r\n- The Issues tab sits in the repository navigation bar directly below the repo name; the open count badge gives a quick pulse check on project health\r\n- Memorize the `G I` keyboard shortcut (press G, release, press I) to jump to Issues from anywhere in the repository without scrolling\r\n- The direct URL pattern works for any repository: swap `[owner]/[repo]` with real values and bookmark your most visited projects\r\n\r\n\r\n## The Issues List Page\r\n\r\n### Page structure\r\n\r\n```\r\n[Search / filter bar]          -- controls at the top\r\n[State tabs: Open / Closed]    -- filter by status\r\n[Issues list]                  -- each issue is one list item or heading\r\n[Pagination]                   -- at the bottom\r\n```\r\n\r\n> **Quick orientation tip:** Press `NVDA+F7` (or `VO+U` on macOS) to open a list of all headings, links, form fields, and buttons on the page. This is often faster than tabbing through many elements and helps you understand the full page structure before diving in. Use `Ctrl+/` (Windows) or `Cmd+/` (Mac) to jump directly to the search field from anywhere on the page.\r\n\r\n### How to read the issue list\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nThe issues list shows each issue as a row with its title, labels, number, assignee avatars, and comment count. Closed issues show a purple merged/closed badge. Click any issue title to open it. Use the **Open** and **Closed** toggle links above the list to switch between states.\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users (zoom, high contrast)</summary>\r\n\r\nEach issue row shows the title, labels (colored badges), number, and comment count. At high magnification:\r\n\r\n- Issue titles are the largest text in each row and remain readable at 200%+ zoom.\r\n- Label badges use colored backgrounds with text inside. In Windows High Contrast mode, labels display with system border colors and readable text rather than colored backgrounds.\r\n- The **Open** and **Closed** toggle links above the list let you switch views. The active toggle is bold or underlined.\r\n- The comment count icon (a speech bubble) may be small at high zoom. It appears to the right of each issue row. Hover to see \"N comments\" tooltip.\r\n- Use `Ctrl+F` (browser Find) to search for a specific issue title if the list is long.\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (NVDA / JAWS)</summary>\r\n\r\n1. Press `D` to reach the “Search Results List” landmark\r\n2. Press `3` (h3) to navigate by issue titles - each issue title is an h3 link\r\n3. Press `I` to move between list items if you want more detail per item\r\n4. Press `Enter` on a title to open that issue\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (VoiceOver)</summary>\r\n\r\n1. `VO+U` → Landmarks → navigate to “Search Results List”\r\n2. `VO+Down` to read through items\r\n3. `H` (with Quick Nav on) or `VO+U` → Headings to jump by issue title\r\n\r\n</details>\r\n\r\n### What is announced per issue\r\n\r\nWhen you navigate to an issue in the list, your screen reader will announce (in some order):\r\n\r\n- Issue title (as a link)\r\n- Issue number (`#42`)\r\n- Labels (e.g., \"bug, good first issue\")\r\n- Who opened it and when (\"Opened 3 days ago by username\")\r\n- Number of comments (\"5 comments\")\r\n\r\n### Learning Cards: The Issues List Page\r\n\r\n<details>\r\n<summary>Screen reader users</summary>\r\n\r\n- Press `D` to jump to the \"Search Results List\" landmark, then press `3` to navigate issue titles (each is an H3 link)\r\n- Press `I` to move between individual list items if you want full detail per issue (number, labels, author, age)\r\n- After applying a filter, the issue list updates silently; press `3` again to re-navigate the updated list from the top\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users</summary>\r\n\r\n- Issue titles are the largest text per row and stay readable at 200%+ zoom; labels appear as small colored badges to the right of each title\r\n- The Open/Closed toggle links are near the top of the list; the active state is bold or underlined depending on your theme\r\n- If the comment count icon (speech bubble) is too small at your zoom level, hover over it for a tooltip showing the exact count\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Sighted users</summary>\r\n\r\n- Each issue row shows: open/closed icon (green circle = open, purple merged icon = closed), title, label badges, PR link icon, comment count, and assignee avatar\r\n- Click the Open/Closed tabs above the list to switch between open and closed issues; the count next to each tab updates as you filter\r\n- Issue labels appear as colored rounded rectangles inline with the title; hover over a label to see its description\r\n\r\n</details>\r\n\r\n\r\n## Filtering and Searching Issues\r\n\r\nFiltering lets you narrow the list to find the right issue quickly.\r\n\r\n### Using the search/filter bar\r\n\r\n1. Press `F` or `E` to jump to the filter input field (or navigate from the landmark)\r\n2. Switch to Focus Mode (`NVDA+Space` / `Insert+Z`) if not already in it\r\n3. Type your filter or search query\r\n4. Press `Enter` to apply\r\n\r\n#### Useful filter queries\r\n\r\n```text\r\nis:open label:\"good first issue\"    ← great for finding your first contribution\r\nis:open label:accessibility         ← accessibility-related open issues\r\nis:open assignee:@me                ← issues assigned to you\r\nis:open no:assignee                 ← unassigned issues\r\nis:open author:@me                  ← issues you filed\r\nmentions:@me                        ← where you were @mentioned\r\nis:open is:unread                   ← issues with unread activity\r\n```\r\n\r\n### Using the filter buttons\r\n\r\nAbove the issue list, there is an **actions toolbar** with filter buttons for Labels, Milestones, Assignees, etc.\r\n\r\n> **Screen reader note:** The filter buttons do not indicate the current filter state. After applying a filter, the button text does not change to reflect what is selected. To verify which filters are active, check the search/filter bar text - it updates to show the active filter conditions (for example, `is:open label:accessibility`).\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nThe filter bar sits above the issue list. Click **Label**, **Milestone**, or **Assignee** to open a dropdown, select the values you want, then click anywhere outside to close. The issue list updates immediately.\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users (zoom, high contrast)</summary>\r\n\r\nThe filter bar sits above the issue list. At high magnification:\r\n\r\n- The **Label**, **Milestone**, and **Assignee** buttons may wrap to a second row. Each button opens a dropdown with searchable options.\r\n- Dropdown menus from filter buttons can extend below the visible viewport at high zoom. Scroll within the dropdown to see all options.\r\n- Type in the search field at the top of each dropdown to narrow the list (for example, type \"accessibility\" in the Label dropdown).\r\n- In Windows High Contrast mode, the selected filter values are indicated with a checkmark icon and system highlight color, not just a background color change.\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (NVDA / JAWS - Windows)</summary>\r\n\r\n1. Press `Tab` from the search bar (or `Shift+Tab` from the issue list) to reach the actions toolbar\r\n2. Press `←/→` to move between toolbar options (Label, Milestone, Assignee, Sort)\r\n3. Press `Enter` to open the selected dropdown\r\n4. Use `↑/↓` to navigate options in the dropdown\r\n5. Press `Enter` or `Space` to select\r\n6.

Press `K` to navigate links until you find them, or look for them as buttons near the search bar.\r\n\r\n### Learning Cards: Filtering and Searching Issues\r\n\r\n**Screen reader users:**\r\n- Switch to Focus Mode (`NVDA+Space`) before typing in the filter bar; switch back to Browse Mode after pressing Enter to read the filtered results\r\n- The filter bar does not announce how many results remain after filtering; press `H` to jump to the issue list heading, then listen for the count in the heading text\r\n- Combine `gh issue list` flags (e.g., `--label \"accessibility\" --assignee @me`) for instant filtered results without navigating dropdown menus\r\n\r\n**Low-vision users:**\r\n- Filter dropdown menus can extend below the viewport at high zoom; scroll within the dropdown or type in the search field at the top of each dropdown to narrow options\r\n- After applying a filter, verify it took effect by checking the search bar text -- it updates to show active conditions like `is:open label:accessibility`\r\n- The `Ctrl+/` (Windows) or `Cmd+/` (Mac) shortcut focuses the search bar instantly, avoiding the need to scroll up to find it\r\n\r\n**Sighted users:**\r\n- Build compound queries in the search bar for precision: `is:open label:\"good first issue\" no:assignee` finds unclaimed starter issues in one step\r\n- The Open/Closed toggle near the top of the list preserves your current filter; click Closed to see resolved issues without losing your label or assignee filter\r\n- Pin your most-used filter as a browser bookmark (the URL updates to reflect the active query) for one-click access\r\n\r\n\r\n## Reading an Issue\r\n\r\n### Landing on an issue page\r\n\r\nWhen you open an issue, the page structure is:\r\n\r\n```text\r\n[Issue title - h1]\r\n[Open/Closed status badge]\r\n[Author, timestamp, comment count]\r\n─────────────────────────────────\r\n[Issue description - Main content]   ← the original post\r\n[Labels, Assignees sidebar - h3s]\r\n─────────────────────────────────\r\n[Activity / Timeline]                ← comments and events\r\n  [First comment - h3]\r\n  [Second comment - h3]\r\n  ...\r\n─────────────────────────────────\r\n[Add a comment - landmark]\r\n[Comment text area]\r\n[Close issue / Submit button]\r\n```\r\n\r\n### Quick navigation\r\n\r\n| Goal | Key |\r\n| ------  | -----  |\r\n| Hear the issue title | `1` |\r\n| Jump to description | `2` (first h2 is usually \"Description\") |\r\n| Jump to Activity section | `2` → next h2 is \"Activity\" |\r\n| Navigate between comments | `3` (each comment is h3) |\r\n| Jump to comment box | `D` → \"Add a comment\" landmark |\r\n| Navigate labels/assignees | `H` or `3` in the sidebar |\r\n\r\n### Reading the issue description\r\n\r\n1. Press `2` to reach the \"Description\" heading\r\n2. Press `↓` to read the content line by line, OR\r\n3. Use `NVDA+↓` (NVDA say all) to have it read continuously\r\n\r\n> **Browse Mode recommended:** The issue detail page is primarily text-based. Stay in **Browse Mode** (not Focus Mode) for reading - it gives you full heading (`H`), section (`D`), and link (`K`) navigation throughout the page. Only switch to Focus Mode when you need to type in a comment box.\r\n\r\nMarkdown in the description renders as proper HTML: headings become actual headings, bullets become lists, code blocks become `<code>` elements with the text \"code block\" announced.\r\n\r\n<details>\r\n<summary>GitHub CLI (gh) alternative - reading an issue</summary>\r\n\r\nView an issue's full content in your terminal:\r\n\r\n```bash\r\n# View issue in terminal (renders Markdown)\r\ngh issue view 42\r\n\r\n# Open the issue in your browser instead\r\ngh issue view 42 --web\r\n\r\n# View just the comments\r\ngh issue view 42 --comments\r\n```\r\n\r\nThe terminal output includes the title, state, labels, assignees, body, and comments. Markdown renders as plain text - headings use `#` symbols, lists use `-`, and code blocks are preserved.\r\n\r\n</details>\r\n\r\n### Reading comments and activity\r\n\r\nEach comment in the thread is marked as an h3. Navigate between them with `3`.\r\n\r\nEach comment announces:\r\n\r\n- Commenter's username\r\n- Timestamp (\"2 days ago\")\r\n- Body text\r\n- Reactions (if any - announced as a button with an emoji and count)\r\n- A \"Reply\" link\r\n\r\nOther timeline events (label added, PR linked, issue closed) appear between comments in the activity stream. They are typically announced as text paragraphs.\r\n\r\n### Learning Cards: Reading an Issue\r\n\r\n<details>\r\n<summary>Screen reader users</summary>\r\n\r\n- Press `1` to hear the issue title, then `2` to reach \"Description\" and \"Activity\" headings, and `3` to jump between individual comments\r\n- Stay in Browse Mode for reading; only switch to Focus Mode (`NVDA+Space`) when you need to type in the comment box\r\n- Press `D` to jump to the \"Add a comment\" landmark at the bottom of the page to skip directly to the reply area\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users</summary>\r\n\r\n- The issue title is the largest text on the page, followed by an Open/Closed badge in green or purple\r\n- Comment blocks have a subtle border and a grey header bar showing the author's avatar and timestamp; zoom in on the header to identify commenters\r\n- The sidebar (Labels, Assignees, Milestone) is on the right at desktop width; at high zoom it may move below the main content\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Sighted users</summary>\r\n\r\n- The issue page has a two-column layout: main content on the left (description, timeline, comment box) and sidebar on the right (labels, assignees, milestone, linked PRs)\r\n- Each comment shows the author's avatar in the left margin, with a header bar containing their username and a relative timestamp\r\n- Timeline events (label changes, assignments, cross-references) appear as small lines between comments with icons indicating the event type\r\n\r\n</details>\r\n\r\n\r\n## Leaving a Comment\r\n\r\n### Step-by-step\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\n1.

Numbered list |\r\n\r\n### GitHub shortcuts for the Issues pages\r\n\r\nThese are the GitHub built-in shortcuts for working with issues. Enable Focus Mode first (NVDA: `NVDA+Space`, JAWS: `Insert+Z`) before using single-key shortcuts.\r\n\r\n#### On the Issues list page\r\n\r\n| Shortcut | Action |\r\n| ---  | ---  |\r\n| `?` | Show all shortcuts for this page |\r\n| `G I` | Jump to the Issues tab from anywhere in the repo |\r\n| `C` | Create a new issue |\r\n\r\n**Shortcut note:** For `G I`, press `G`, release it, then press `I` (two sequential key presses, not simultaneous).\r\n| `Ctrl+/` (Win) or `Cmd+/` (Mac) | Focus the issues search and filter bar |\r\n| `U` | Filter by author |\r\n| `L` | Filter by or edit labels |\r\n| `M` | Filter by or edit milestones |\r\n| `A` | Filter by or edit assignee |\r\n| `O` or `Enter` | Open the selected issue |\r\n\r\n#### On an open issue\r\n\r\n| Shortcut | Action |\r\n| ---  | ---  |\r\n| `M` | Set a milestone |\r\n| `L` | Apply a label |\r\n| `A` | Set an assignee |\r\n| `X` | Link a related issue from the same repository |\r\n| `R` | Quote selected text in your reply (select text first) |\r\n| `Ctrl+Shift+P` (Win) or `Cmd+Shift+P` (Mac) | Toggle Write and Preview tabs |\r\n| `Ctrl+Enter` | Submit comment from inside the text area |\r\n\r\n> **`R` to quote is a power move:** Select any text in a comment while in Browse Mode (`Shift+Arrow` to select), then press `R`. GitHub puts the quoted text in the comment box as a Markdown blockquote. Much faster than typing `>` manually.\r\n\r\nFor the full shortcut system, see [Screen Reader Cheat Sheet - GitHub Shortcuts section](appendix-b-screen-reader-cheatsheet.md#github-built-in-keyboard-shortcuts).\r\n\r\n1.

Open the **GitHub** panel in the sidebar.\r\n2. Under **Issues**, click the **+** icon to create a new issue.\r\n3.

Click **Repository > View on GitHub** to open the browser, then file the issue there.\r\n\r\n**Git CLI / GitHub CLI:**\r\n```bash\r\ngh issue create --title \"Your title\" --body \"Description here\"\r\n# Or interactively:\r\ngh issue create\r\n```\r\n\r\n\r\n## Cross-Referencing Issues\r\n\r\nLinking issues and PRs to each other creates a trail of context that helps everyone understand the project's history.\r\n\r\n### Closing keywords in PR descriptions or issue comments\r\n\r\nWhen you type these phrases in a PR description or comment (followed by an issue number), GitHub creates a connection:\r\n\r\n| Keyword | Effect on merge |\r\n| ---------  | ----------------  |\r\n| `Closes #42` | Closes issue #42 when the PR merges |\r\n| `Fixes #42` | Same - typically for bugs |\r\n| `Resolves #42` | Same - general use |\r\n| `refs #42` | Creates a reference without auto-closing |\r\n| `cc @username` | Notifies the person |\r\n\r\n### Mentioning another issue in a comment\r\n\r\nSimply type `#` followed by a number anywhere in a comment body. GitHub autocompletes with a dropdown of matching issues and PRs:\r\n\r\n```text\r\nStep 1: Type # in the comment box (Focus Mode)\r\nStep 2: A dropdown appears with issues and PRs\r\nStep 3: ↑/↓ to navigate, or type more numbers to filter\r\nStep 4: Enter to insert the reference\r\n```\r\n\r\n### Cross-repo references\r\n\r\n`owner/repo#42` - references issue #42 in a different repository.\r\n\r\n### Learning Cards: Cross-Referencing Issues\r\n\r\n**Screen reader users:**\r\n- Type `#` in any comment body to trigger GitHub's autocomplete dropdown; press `Down Arrow` to browse matching issues and `Enter` to insert the reference link\r\n- Use `Closes #42` (not just `#42`) in PR descriptions so GitHub automatically closes the issue on merge; your screen reader will confirm the link is created in the PR timeline\r\n- Cross-references appear as timeline events on the linked issue; navigate with `H` to find \"mentioned this issue\" entries to trace the conversation history\r\n\r\n**Low-vision users:**\r\n- Cross-reference links (`#42`) render as colored, clickable links in both issue bodies and PR descriptions; at high zoom they remain inline with surrounding text\r\n- The autocomplete dropdown triggered by `#` may overlap content at high magnification; type additional digits to narrow results and reduce dropdown size\r\n- Back-links appear automatically on the referenced issue's timeline, so you can verify the connection was created by visiting either side\r\n\r\n**Sighted users:**\r\n- Use `Closes #42`, `Fixes #42`, or `Resolves #42` in PR descriptions for auto-closing on merge; `refs #42` creates a reference without auto-close, useful for \"related but not solved\" links\r\n- GitHub's autocomplete (`#` then type) searches both issue titles and numbers, so you can find issues by keyword without memorizing numbers\r\n- Cross-repo references use the format `owner/repo#42` -- useful when your PR in one repository fixes a bug tracked in another\r\n\r\n\r\n## Sub-Issues - Parent and Child Relationships\r\n\r\n**Sub-issues** (released 2025) let you nest issues inside a parent issue to break large work into tracked pieces. A \"parent\" issue contains a list of child issues; each child is a full issue with its own discussion, labels, and assignees.\r\n\r\n### When to Use Sub-Issues\r\n\r\n| Use case | Example |\r\n| ----------  | ---------  |\r\n| Large feature broken down | Parent: \"Redesign navigation\"; Children: \"Keyboard nav,\" \"Screen reader nav,\" \"Mobile nav\" |\r\n| Epic tracking | Parent: \"WCAG 2.1 AA compliance\"; Children: one issue per failing criterion |\r\n| Release milestone | Parent: \"v2.0 release\"; Children: every required PR/fix |\r\n\r\n### Creating a Sub-Issue\r\n\r\nFrom any open issue:\r\n\r\n```text\r\n1. Open the parent issue page\r\n2. Scroll to (or H-navigate to) the \"Sub-issues\" section in the issue body/sidebar\r\n3. Tab to \"Add sub-issue\" button → Enter\r\n4. Type the issue number or title to search\r\n5. Select the issue from the dropdown → Enter to link\r\n   Or: select \"Create new issue\" to create and link in one step\r\n```\r\n\r\n**Screen reader note:** The sub-issues section is announced as a region. After linking, the child issue appears as a list item with a checkbox showing its open/closed state. Tab through to read each child's title and status.\r\n\r\n### Reading Sub-Issues on a Parent Issue\r\n\r\n```text\r\nH → \"Sub-issues\" heading\r\n↓ → list of linked child issues\r\nEach item: [checkbox state] [issue title] [#number] [open/closed badge]\r\nTab → \"Add sub-issue\" button (if you have write access)\r\n```\r\n\r\n**Progress indicator:** The parent issue shows a completion bar (e.g., \"3 of 7 completed\") based on how many child issues are closed. Screen readers announce this as a progress region.\r\n\r\n### Viewing a Child Issue's Parent\r\n\r\nEvery child issue shows a \"Parent issue\" link near the top of the page (above the description). Navigate with `H` or links (`K`) to find it.\r\n\r\n### Sub-Issues vs. Task Lists\r\n\r\n| Feature | Task list checkboxes | Sub-issues |\r\n| ---------  | ---------------------  | ------------  |\r\n| Location | Issue description (Markdown) | Sidebar/section (structured data) |\r\n| Each item is | Text line + checkbox | A full GitHub issue |\r\n| Tracked in Projects | No (checkbox only) | Yes (each child tracks independently) |\r\n| Cross-repo | No | Yes |\r\n| Best for | Quick checklists in one issue | Multi-issue work tracking |\r\n\r\n> **Workshop tip:** If you are working on a feature that requires multiple PRs or involves several team members, ask the maintainer to create a parent issue. You can then claim individual child issues without one person owning the whole feature.\r\n\r\n### Learning Cards: Sub-Issues\r\n\r\n**Screen reader users:**\r\n- The sub-issues section is announced as a region; press `H` to navigate to the \"Sub-issues\" heading, then arrow down through the list where each child announces its checkbox state, title, and open/closed badge\r\n- The parent issue shows a progress indicator (\"3 of 7 completed\") announced as a progress region; listen for this after the sub-issues heading to gauge overall status\r\n- Every child issue includes a \"Parent issue\" link near the top of its page; navigate with `K` (links) to find it and jump back to the parent quickly\r\n\r\n**Low-vision users:**\r\n- The completion progress bar on the parent issue uses color to show progress; in high-contrast mode, completed vs. remaining segments use distinct system colors\r\n- At high zoom, the \"Add sub-issue\" button may wrap below the sub-issues list; Tab past the last child item to reach it\r\n- Each child issue's open/closed badge uses both color and text (\"Open\" or \"Closed\"), so status is readable without relying on color alone\r\n\r\n**Sighted users:**\r\n- Sub-issues appear as a checklist with a progress bar on the parent issue; each child links directly to its own issue page with full discussion and labels\r\n- Use sub-issues instead of Markdown task-list checkboxes when each item needs its own assignee, labels, or cross-repo tracking -- sub-issues are structured data, not just text\r\n- Creating a sub-issue from the parent's \"Add sub-issue\" button auto-links the new issue; you can also link existing issues by searching their number or title\r\n\r\n\r\n## Managing Issues (for Maintainers and Triagers)\r\n\r\n### Closing an issue\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nScroll to the bottom of the issue page.

Press Escape to save\r\n\r\n### Transferring or deleting an issue\r\n\r\nAvailable from the \"...\" (ellipsis) button at the top of the issue - navigate buttons with `B` to find it.\r\n\r\n### Learning Cards: Managing Issues\r\n\r\n**Screen reader users:**\r\n- Close an issue instantly with `Ctrl+Shift+Enter` from the comment text area (Focus Mode) -- no need to Tab to the Close button\r\n- The sidebar sections (Assignees, Labels, Milestone) each have their own heading; press `H` or `3` to jump between them, then activate the gear icon to open each dropdown\r\n- Use `gh issue edit 42 --add-label \"accessibility\" --add-assignee @me` to batch-update labels and assignments from the terminal without navigating sidebar controls\r\n\r\n**Low-vision users:**\r\n- Sidebar controls (Assignees, Labels, Milestone) are narrow at default width; at high zoom they stack vertically and each dropdown opens a searchable overlay that is easier to read\r\n- The Close issue button turns green and its label changes to \"Reopen issue\" once closed; in high-contrast mode, both states use distinct system colors\r\n- Type in the search field inside each sidebar dropdown (Labels, Assignees) to filter long lists rather than scrolling through all options at high magnification\r\n\r\n**Sighted users:**\r\n- The issue sidebar on the right contains Assignees, Labels, Projects, and Milestone in collapsible sections; click the gear icon next to each to open the edit dropdown\r\n- Use the dropdown arrow on the Close button to choose \"Close as completed\" vs. \"Close as not planned\" -- this distinction helps with project tracking and search filtering\r\n- The \"...\" menu at the top of any issue provides Transfer, Pin, Lock, and Delete options for repository maintainers\r\n\r\n\r\n## The \"good first issue\" Label - Your Entry Point\r\n\r\nWhen looking for your first open source contribution:\r\n\r\n1. Navigate to any project's Issues tab\r\n2. Filter by label: type `is:open label:\"good first issue\"` in the search\r\n3. Read through issues until you find one in your area of interest\r\n4. Comment on the issue: \"Hi, I'd like to work on this. Can I be assigned?\"\r\n5. Wait for a maintainer to respond and assign you before starting work\r\n\r\n**Remember:** It's respectful to ask before starting. Maintainers juggle many discussions and need to know who is working on what to avoid duplicated effort.\r\n\r\n### Learning Cards: The \"good first issue\" Label\r\n\r\n**Screen reader users:**\r\n- Use the filter query `is:open label:\"good first issue\"` in the search bar to jump directly to beginner-friendly issues; `gh issue list --label \"good first issue\"` does the same in the terminal\r\n- Before claiming an issue, read existing comments to check whether someone else has already been assigned; listen for \"assigned to\" in the sidebar metadata\r\n- When you comment to claim an issue, include a sentence about your approach so the maintainer can give early feedback before you start coding\r\n\r\n**Low-vision users:**\r\n- The \"good first issue\" label renders with a distinct background color (typically light purple or teal); in high-contrast mode it uses system highlight colors with readable text\r\n- Filter results may include issues with multiple labels stacked together; at high zoom, labels wrap to a second line but remain readable\r\n- Bookmark the filtered URL (`/issues?q=is:open+label:\"good first issue\"`) in your browser for one-click access to beginner issues across your favorite repositories\r\n\r\n**Sighted users:**\r\n- The \"good first issue\" label is a GitHub convention recognized across the ecosystem; many projects also use \"help wanted\" for intermediate tasks\r\n- Always comment before starting work -- even if unassigned -- to avoid duplicating effort with another contributor who may already be working quietly\r\n- Read the issue's linked PR history (if any) to see whether previous attempts were made and why they were closed; this saves you from repeating known dead ends\r\n\r\n\r\n## Accessibility-Specific Issue Writing Tips\r\n\r\nWhen filing accessibility bugs, these details help maintainers reproduce and fix the problem:\r\n\r\n1. **Screen reader and version** - \"NVDA 2025.3.3\" not just \"screen reader\"\r\n2. **OS and version** - \"Windows 11 22H2\"\r\n3. **Browser and version** - \"Chrome 124.0.6367.82\"\r\n4. **GitHub interface** - \"Modern experience (default since Jan 2026)\" or \"Classic experience (opted out)\"\r\n5. **What was announced** - quote the exact text your screen reader spoke\r\n6. **What should have been announced** - describe the expected behavior\r\n7. **ARIA issue if known** - e.g., \"The button has no accessible name\"\r\n8. **Steps to reproduce** - numbered, step-by-step\r\n9. **Frequency** - \"This happens every time\" vs \"intermittent\"\r\n\r\n### Example of a well-filed accessibility issue\r\n\r\n```text\r\nTitle: Issues list does not announce label filtering results to screen readers\r\n\r\n## What happened\r\nWhen I apply a label filter on the Issues list using the Labels dropdown,\r\nthe filtered list updates visually but NVDA does not announce that the\r\nresults changed or how many items are now shown.\r\n\r\n## What I expected\r\nAfter filtering, the screen reader should announce something like\r\n\"14 issues open, filtered by label: accessibility\" or a live region\r\nupdate indicating the results changed.\r\n\r\n## How to reproduce\r\n1.

VoiceOver on macOS Sonoma with\r\nSafari 17 does announce \"List updated\" when filtering is applied,\r\nso the macOS behavior appears correct.\r\n```\r\n\r\n### Learning Cards: Accessibility-Specific Issue Writing\r\n\r\n**Screen reader users:**\r\n- Always quote the exact text your screen reader announced in the issue body; wrap it in a fenced code block so readers know it is literal output, not your description\r\n- Include your screen reader name and version (e.g., \"NVDA 2025.3.3\") plus browser and OS; this lets maintainers reproduce with the same toolchain\r\n- Test with a second screen reader or browser if possible and note the results -- \"Also fails in JAWS 2026 with Chrome; works in VoiceOver with Safari\" dramatically narrows the debugging scope\r\n\r\n**Low-vision users:**\r\n- When filing zoom or contrast bugs, state your exact zoom level and whether you use Windows High Contrast, macOS Increase Contrast, or a browser extension\r\n- Screenshots are powerful evidence; annotate them (circle the problem area, add a text callout) and always include alt text describing what the screenshot shows\r\n- Note whether the issue occurs only at certain zoom levels or viewport widths; a bug at 400% that disappears at 200% points to a CSS breakpoint problem\r\n\r\n**Sighted users:**\r\n- Even if you do not use assistive technology, you can file accessibility issues by testing with keyboard-only navigation (Tab, Enter, Escape) and noting where focus is lost or trapped\r\n- Include the ARIA role or attribute involved if you can identify it from browser DevTools (e.g., \"The button has `role=presentation` and no accessible name\")\r\n- Link to the relevant WCAG success criterion when possible (e.g., \"Fails WCAG 2.1 SC 1.3.1 Info and Relationships\"); this gives maintainers a clear standard to design against\r\n\r\n\r\n## Writing Effective Issues\r\n\r\n> **See also:** [Appendix N: Advanced Search](appendix-n-advanced-search.md) covers search qualifiers to find existing issues before filing a new one.\r\n\r\nA well-written issue saves everyone time -- the maintainer who reads it, the contributor who fixes it, and the future searcher who finds it six months later. This section gives you reusable templates for the two most common issue types and a set of principles that apply to every issue you file.\r\n\r\n### Bug Report Structure\r\n\r\nA strong bug report answers five questions. Use this template every time you report something broken.\r\n\r\n| Section | What to write |\r\n|---|---|\r\n| **Title** | Follow the formula: \"When I [action], [unexpected result] instead of [expected result]\" |\r\n| **Steps to Reproduce** | Numbered list -- start from the earliest relevant step |\r\n| **Expected Behavior** | What *should* happen according to documentation or common sense |\r\n| **Actual Behavior** | What *does* happen -- include exact error messages or screenshots |\r\n| **Environment** | OS, browser, screen reader, app version -- anything that might matter |\r\n\r\nThe title formula is the most important part. A title like \"When I press Enter on the Submit button, nothing happens instead of creating the issue\" tells the maintainer exactly what is broken before they even open the issue.\r\n\r\n> **Screen reader tip:** When pasting error messages into the Actual Behavior section, wrap them in a fenced code block (triple backticks). Screen readers will announce \"code block\" so the listener knows the text is a literal error, not your description.\r\n\r\n**Steps to Reproduce matter more than you think.** Maintainers cannot fix what they cannot recreate. Number every step, starting from a clean slate -- \"Open the repository\" is better than \"Go to the page.\" Include what you clicked, what keyboard shortcut you pressed, and what happened after each step.\r\n\r\n### Feature Request Structure\r\n\r\nFeature requests work best when they focus on the *problem* before jumping to the solution. Use this four-part structure:\r\n\r\n1. **Problem statement** -- Describe the pain point. What are you trying to do, and why is it hard or impossible right now?\r\n2. **Proposed solution** -- Your best idea for fixing the problem. Be specific enough to discuss, but hold it loosely.\r\n3. **Alternatives considered** -- Other approaches you thought about and why they fell short. This shows you have done your homework.\r\n4. **Who benefits** -- Name the audience. \"Screen reader users navigating large repositories\" is more compelling than \"everyone.\"\r\n\r\nA feature request that starts with \"I want a dark mode toggle\" is weaker than one that starts with \"Low-vision users report eyestrain after 20 minutes because the current theme has insufficient contrast.\" The second version gives maintainers something to design around.\r\n\r\n### General Issue Writing Principles\r\n\r\nThese rules apply to every issue -- bugs, features, questions, and everything in between.\r\n\r\n**One issue per problem.** If you discovered two bugs during the same session, file two separate issues. Combining them makes it impossible to close one without the other and clutters the conversation.\r\n\r\n**Write searchable titles.** Future contributors will search before filing. \"Bug with button\" will never surface in a search for \"Submit button unresponsive on Safari.\" Front-load the title with the specific component or action.\r\n\r\n**Include context, not assumptions.** Instead of \"The API is broken,\" write \"The `/repos` endpoint returns a 403 when I pass a valid token.\" Let maintainers draw their own conclusions from the evidence you provide.\r\n\r\n**Link related issues.** If your bug might be connected to issue #42, mention it: \"This might be related to #42.\" GitHub automatically creates a back-link, building a web of context that helps everyone. You will learn more about cross-referencing in [Chapter 6](06-working-with-pull-requests.md).\r\n\r\n| Principle | Bad example | Good example |\r\n|---|---|---|\r\n| One issue per problem | \"The button is broken and also the logo is wrong\" | Two separate issues, each with its own title |\r\n| Searchable title | \"Help needed\" | \"Keyboard focus lost after closing modal dialog\" |\r\n| Context over assumptions | \"Nothing works\" | \"After upgrading to v2.3, the dashboard returns a blank page on Firefox 124\" |\r\n| Link related issues | (no mention) | \"Possibly related to #42 -- same component, different trigger\" |\r\n\r\n### Before and After: A Vague Issue vs. a Clear Issue\r\n\r\n**Vague issue (hard to act on):**\r\n\r\n> **Title:** Bug\r\n>\r\n> It doesn't work. I tried clicking and nothing happened. Please fix.\r\n\r\nThe maintainer has to ask: What doesn't work? Where did you click? What browser? What did you expect? Every follow-up question costs a round-trip of waiting.\r\n\r\n**Clear issue (ready to fix):**\r\n\r\n> **Title:** When I press Enter on the \"New issue\" button, nothing happens instead of opening the issue form\r\n>\r\n> **Steps to Reproduce:**\r\n> 1. Navigate to github.com/org/repo\r\n> 2. Press `G` then `I` to go to the Issues tab\r\n> 3. Tab to the \"New issue\" button\r\n> 4. Press `Enter`\r\n>\r\n> **Expected:** The new issue form opens.\r\n>\r\n> **Actual:** The page does not respond. No error in the console.\r\n>\r\n> **Environment:** Windows 11, Firefox 128, JAWS 2025\r\n\r\nThe maintainer can reproduce this in under a minute. No follow-up questions needed -- the fix can start immediately.\r\n\r\n> **Screen reader tip:** You can use the issue template feature in GitHub to pre-fill these sections automatically. If the repository provides templates, your screen reader will announce each section heading as you Tab through the form. You will set up your own issue templates in [Chapter 17](17-issue-templates.md).\r\n\r\n### Learning Cards: Writing Effective Issues\r\n\r\n<details>\r\n<summary>Screen reader users</summary>\r\n\r\n- Use fenced code blocks (triple backticks) when pasting error messages or screen reader output; your screen reader announces \"code block\" so listeners know the text is literal, not description\r\n- When writing \"Steps to Reproduce,\" type each step as a numbered Markdown list item (`1.`, `2.`, etc.) so screen readers announce \"list with N items\"\r\n- Type `#` in the comment body to trigger issue autocomplete; press `Down Arrow` to navigate matching issues and `Enter` to insert a cross-reference link\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users</summary>\r\n\r\n- Use the Preview tab (next to Write) to check your Markdown rendering before submitting; headings, bold text, and code blocks are much easier to proofread in rendered form\r\n- Screenshots with alt text are valuable evidence; add them with the image button in the formatting toolbar or drag-and-drop into the body field\r\n- Keep paragraphs short (3-4 sentences max) so the issue is scannable at high zoom without excessive scrolling\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Sighted users</summary>\r\n\r\n- A well-structured issue uses H2 headings (##) for major sections: What happened, Expected, How to reproduce, Environment\r\n- GitHub renders Markdown tables in issue bodies; use a table to compare expected vs. actual behavior side by side\r\n- The title appears in issue lists, email notifications, and search results; front-load it with the specific component or action for discoverability\r\n\r\n</details>\r\n\r\n\r\n## Try It: File Your First Issue\r\n\r\n**Time:** 3 minutes | **What you need:** Browser, signed in to GitHub\r\n\r\nGo to the Learning Room repository and file a real issue:\r\n\r\n1. Navigate to the Issues tab (press `G` then `I` in Focus Mode)\r\n2. Find and activate the \"New issue\" button (`K` to links, or `Tab` to it)\r\n3. In the title field, type: **\"Introduce myself - [Your Name]\"**\r\n4. In the description, write 2-3 sentences: who you are, what screen reader you use, and one thing you're hoping to learn today\r\n5. Press `Ctrl+Enter` to submit (or Tab to the Submit button and press `Enter`)\r\n\r\n**You're done.** You just filed your first GitHub issue. Go read someone else's introduction and leave a friendly comment - press `3` to jump between issue titles on the Issues list.\r\n\r\n> **What success feels like:** Your issue is live. Other participants can see it. You just contributed to a real repository - and it took less than three minutes.\r\n\r\n### Learning Cards: Filing Your First Issue\r\n\r\n**Screen reader users:**\r\n- After pressing `Ctrl+Enter` to submit, listen for the page reload; GitHub navigates to your new issue page where the title is the first heading -- press `1` to confirm it matches what you typed\r\n- Navigate the issue list with `3` (heading level 3) to jump between issue titles; this is faster than arrowing through every element on the page\r\n- If the template picker appears, use `Tab` and `Enter` to select \"Open a blank issue\"; template names are announced as link text\r\n\r\n**Low-vision users:**\r\n- The \"New issue\" button is prominent and green on the Issues list page; at high zoom it remains visible near the top of the page and does not collapse into a menu\r\n- The title field is full-width and the body field expands as you type; both are easy to locate and target at any zoom level\r\n- After submitting, your new issue page shows your avatar, title, and description in high-contrast-friendly layout; verify the content rendered correctly before moving on\r\n\r\n**Sighted users:**\r\n- Your issue immediately appears at the top of the Issues list; the green \"Open\" badge confirms it was created successfully\r\n- Read a few other students' introduction issues and leave a comment to practice the commenting workflow from the Leaving a Comment section\r\n- Notice how the issue number (e.g., #150) is auto-assigned and appears in the URL and page title; you will use this number for cross-references later\r\n\r\n\r\n> ### Day 2 Amplifier - Accessibility Agents: `@issue-tracker`\r\n>\r\n> **File, read, comment on, and triage real issues manually before using any agent.** If you have not done the triage work yourself - reading descriptions, assigning labels, identifying duplicates - you cannot evaluate whether an agent's priority scoring is correct. The skill must exist before the amplifier is useful.\r\n>\r\n> Once you have mastered manual issue management:\r\n>\r\n> - **In VS Code** - `@issue-tracker find open issues labeled good-first-issue` searches cross-repository with community sentiment scoring, release-awareness prioritization, and batch-reply capability across every repo you have access to\r\n> - **In your repo** - The issue templates in `accessibility-agents/.github/ISSUE_TEMPLATE/` structure both human filing and automated triage; fork [accessibility-agents](https://github.com/Community-Access/accessibility-agents) and that structure travels into any project you lead\r\n> - **In the cloud** - GitHub Agentic Workflows triage new issues the moment they are opened: applying labels, posting first-response comments, adding to Project boards - the same triage actions you practiced manually today, running at scale\r\n>\r\n> *Today you are the triage engine. On Day 2, you understand the engine well enough to direct it.*\r\n\r\n\r\n> **Challenge Time:** It's time for the real deal. Go to the [Challenge Hub](CHALLENGES.md) and complete **Challenge 2: File Your First Issue** and **Challenge 3: Join the Conversation**. When Aria the bot replies to you, she will tell you when it's time to move to [Chapter 06: Working with Pull Requests](06-working-with-pull-requests.md).\r\n\r\n---\r\n\r\n\r\n*Next: [Chapter 06: Working with Pull Requests](06-working-with-pull-requests.md)*  \r\n*Back: [Chapter 04: The Learning Room](04-the-learning-room.md)*  \r\n*Related appendices: [Appendix N: Advanced Search](appendix-n-advanced-search.md) | [Appendix V: GitHub Mobile](appendix-v-github-mobile.md)*\r\n\r\n\r\n\r\n\r\n"

+[ALEX]
+Welcome back. In this lesson, we are working with GitHub Issues. And even if the word issue sounds like it means something went wrong, that is not the only job these are doing. In a lot of projects, an issue is just the shared record for a piece of work. It can describe a bug, a question, a task, an idea, a request, or a reminder. What matters is that everyone can point to the same place, see the same context, and add to the conversation over time.
+
+[JAMIE]
+So this is less problem list and more collaboration log?
+
+[ALEX]
+Exactly. A good issue gives work a home. Instead of details getting lost in chat, email, or memory, the issue holds the title, the description, the updates, and the decisions. It becomes the place the team can return to.
+
+[JAMIE]
+That helps, because a lot of learners see the Issues tab and assume, I must have broken something.
+
+[ALEX]
+That reaction is common. In this workshop, think of issues as working notes that are visible to the whole project. Some will describe real bugs. Some will just describe something the team wants to do next. Both belong there.
+
+[PAUSE]
+
+[ALEX]
+For this chapter, the workshop gives you a recommendation and a challenge. The recommendation is the core path: create your first issue, fill it in clearly, and interact with it the way a collaborator would. The challenge pushes a little further. If you want more practice, you can explore things like sub-issues, extra filtering, or alternative ways to work, including doing part of this locally with Git or the GitHub CLI.
+
+[JAMIE]
+So nobody is being asked to master every advanced feature right away?
+
+[ALEX]
+Right. The expected outcome is not know every issue feature. The expected outcome is simpler and more useful: you should be able to find the Issues area, understand what you are looking at, create an issue that another person can actually use, and participate in the follow-up conversation.
+
+[JAMIE]
+That sounds like a realistic workshop target.
+
+[ALEX]
+It is. And it also matches real team habits. Clear, usable issue writing helps other people move faster. It also helps future-you.
+
+[PAUSE]
+
+[ALEX]
+Let us orient ourselves first. In a repository on GitHub, the Issues tab is one of the main navigation areas. If you use a mouse, you can select it from the top navigation. If you use a keyboard, tabbing through the repository navigation should eventually land on Issues, and screen readers will usually announce it as a tab or navigation item in the repository header area, depending on the page structure.
+
+[JAMIE]
+And once you open it, what should people expect on the page?
+
+[ALEX]
+Usually, an issue list page. That page has a few distinct parts. You will typically find controls for filtering and searching. You will see a button to create a new issue. And below that, you will see rows for existing issues.
+
+[JAMIE]
+Those rows can be a little dense at first.
+
+[ALEX]
+They can, so it helps to know what each row is trying to tell you. A row usually includes the issue title first, because that is the fastest signal about what the item is. You may also hear or see the issue number, whether it is open or closed, who opened it, and other metadata like labels, comments, or related work. If you are using a screen reader, move through the row carefully. The title link is usually the main entry point, but the surrounding text provides the status and context that help you decide whether this is the item you want.
+
+[JAMIE]
+So if I am scanning the list, I am not just reading titles. I am also reading status.
+
+[ALEX]
+Yes. The list is doing triage work for you. It helps you answer questions like: Is this still active? Is there already a conversation about the thing I was about to bring up? Does a label tell me this is documentation, accessibility, bug fixing, or enhancement work?
+
+[PAUSE]
+
+[ALEX]
+Filtering and search matter a lot here. On active projects, the issue list can get crowded fast. Search lets you find terms inside issue titles and sometimes body text depending on how you search. Filters help you narrow by status, author, labels, assignees, and other properties. Even if you only learn a few filters today, that is enough to avoid duplicating work that already has an issue.
+
+[JAMIE]
+That is an important point. Before creating a new issue, look to see whether someone already opened one.
+
+[ALEX]
+Exactly. It is respectful to the team, and it keeps discussion from splitting into multiple places. If you are using a keyboard, spend a moment learning where the search field and filter controls are on the page. If you have low vision, zooming in or increasing browser text size can change the layout, so the controls may wrap or move. That is normal. Give yourself permission to slow down and re-scan the page structure. If you use a screen reader, headings, landmarks, and form fields are your friends here. They make the list page much easier to navigate than trying to read every item in sequence.
+
+[JAMIE]
+That is a good workshop habit in general: do not fight the whole page if the page already has structure you can use.
+
+[ALEX]
+Exactly right.
+
+[PAUSE]

+Now, the create-your-first-issue flow. Once you are in the Issues area, you open the new issue form. Depending on the repository, you may see a simple blank form, or you may see templates that guide different kinds of requests. For this lesson, the important thing is the writing, not memorizing every repository-specific screen.
+
+[JAMIE]
+What makes a first issue good enough?
+
+[ALEX]
+Two things immediately: a useful title and a useful body. The title should help someone understand the topic before they even open the issue. Not perfect. Just specific enough to be informative. Fix stuff is not helpful. Clarify setup instructions for Windows learners is much better. Add alt text to lesson screenshots is much better. A clear title reduces guesswork.
+
+[JAMIE]
+And the body is where you give the rest of the picture.
+
+[ALEX]
+Yes. The body should answer the natural follow-up questions. What are you seeing? What are you trying to do? Why does it matter? If this is a task, what outcome are you aiming for? If this is a problem, how can someone else recognize it? If there is evidence, include it.
+
+[JAMIE]
+What counts as evidence here?
+
+[ALEX]
+Anything that helps another person understand the situation without recreating all of your steps from scratch. That could be a short description of what happened, the exact text of an error message, a screenshot if that is appropriate, or the steps you took before the issue appeared. For accessibility-related issues, evidence might also include what assistive technology you used, what browser or device you were on, and what behavior made the experience difficult.
+
+[JAMIE]
+That last part matters. This page is inaccessible is too vague to act on.
+
+[ALEX]
+Right. A better issue body gives someone a path to investigate. For example: Using keyboard only, I could reach the navigation but not the submit button. Or: With screen reader reading mode, the issue rows were announced, but the status was not obvious until I moved line by line. That is actionable.
+
+[PAUSE]
+
+[JAMIE]
+Let me ask a beginner question. How polished does the body need to be? Some learners freeze because they think they need to write like a product manager.
+
+[ALEX]
+You do not need a polished memo. You need enough clarity for another person to understand the work. A short, direct issue is often better than a long vague one. If you can answer who, what, where, and why this matters, you are usually in good shape.
+
+[JAMIE]
+So if the title is specific and the body gives context and evidence, that is already a solid issue.
+
+[ALEX]
+Yes. And this workshop is trying to build that habit. Not perfection. Usability.
+
+[PAUSE]
+
+[ALEX]
+After the issue exists, the collaboration part continues in comments. Comments let people ask questions, add updates, attach evidence, suggest approaches, or record decisions. This is where you see why issues are records, not just forms.
+
+[JAMIE]
+And this is where mentions come in too.
+
+[ALEX]
+Yes. If you type an at-sign and a username, GitHub can notify that person. Mentions matter because they connect the conversation to the right people. If you need input from a maintainer, a reviewer, or a teammate, an @mention brings them into the thread directly rather than hoping they happen to notice the issue later.
+
+[JAMIE]
+So it is not just tagging for the sake of tagging. It is routing attention.
+
+[ALEX]
+That is a good way to put it. Mentions help route attention. They are especially useful when a conversation reaches a point where a specific person needs to review, answer, or approve something.
+
+[JAMIE]
+Any caution there?
+
+[ALEX]
+Use mentions intentionally. If you mention five people every time, it stops being helpful. Mention the person who is genuinely relevant to the next step.
+
+[JAMIE]
+And if someone mentions you, the expectation is that the issue is now your place to respond, not a private side conversation somewhere else.
+
+[ALEX]
+Exactly. Keeping the response in the issue preserves the shared record.
+
+[PAUSE]
+
+[ALEX]
+Some projects also use sub-issues. These are optional, and you do not need them for every task. They help when one larger piece of work naturally breaks into smaller, trackable parts. Imagine an issue for improving a lesson page. That larger issue might be easier to manage if it links to separate smaller issues for updating screenshots, fixing keyboard focus order, and revising the written instructions.
+
+[JAMIE]
+So the parent issue says, here is the broader job, and the sub-issues capture the individual chunks?
+
+[ALEX]
+That is the idea. It helps when work has multiple contributors, or when progress is easier to track as a set of smaller outcomes. But for a simple task, making sub-issues can create more overhead than value. Use them when they make the work clearer, not when they just make the project look more complicated.
+
+[JAMIE]
+That distinction helps. Optional means optional.
+
+[ALEX]
+Exactly.
+
+[PAUSE]
+
+[ALEX]
+The chapter also expects some kind of evidence submission from you as you work through the exercise. In workshop terms, that usually means showing what you created or what you observed. It might be the issue you opened, a screenshot of the issue page, a link to the issue, or a short note describing the comments or mentions you added.
+
+[JAMIE]
+So the evidence is not busywork. It proves you can move through the flow.
+
+[ALEX]
+Right. It gives the instructor, or your future self, something concrete to check. Did you open the issue? Did you write a useful title? Did you add enough context? Did you interact with the conversation? The evidence should make those answers visible.
+
+[JAMIE]
+And that ties back to the expected outcomes.
+
+[ALEX]
+Yes. By the end, you should be able to say: I know where issues live in a repository. I can read the list without feeling lost. I can create an issue that is specific and useful. I can comment on an issue. I understand why @mentions matter. I know when sub-issues might help. And I can document what I did.
+
+[PAUSE]
+
+[JAMIE]
+Let us talk about getting stuck, because this is one of those places where people can get blocked by small things. Maybe they cannot find the right button. Maybe they are unsure whether their issue is good enough. Maybe the page layout looks different from the lesson.
+
+[ALEX]
+That is exactly the kind of friction this chapter anticipates. If you get stuck, the recovery guidance is simple and practical. First, check whether you are in the right repository area. It sounds obvious, but a lot of confusion comes from being in Pull Requests, Discussions, or Code when you meant to be in Issues. Second, look for an existing issue before opening a new one, because the answer or context may already be there. Third, if the layout differs from the screenshots or lesson text, focus on the function of the page, not matching the page pixel for pixel.
+
+[JAMIE]
+Meaning: find the list, the search and filter controls, and the create button, even if the interface has shifted around.
+
+[ALEX]
+Exactly. And if writing the issue body feels hard, reduce the problem. Write the title first. Then answer one question at a time: what is happening, what did I expect, and what evidence can I provide? That is often enough to break the freeze.
+
+[JAMIE]
+What if someone is using assistive tech and the obstacle itself is access?
+
+[ALEX]
+Then document that directly. If keyboard navigation is trapping you, say so. If a control is hard to identify at high zoom, say so. If a screen reader announces the page in a confusing order, say so. Accessibility blockers are real blockers, and naming them clearly is part of the work, not a distraction from it.
+
+[JAMIE]
+That is worth hearing out loud.
+
+[ALEX]
+It is. In this chapter, accessibility is not an extra topic off to the side. It is integrated into how you use the tool. A keyboard user may navigate the issue list differently from a mouse user. A low-vision learner may rely on zoom, contrast settings, or careful scanning of headings and labels. A screen-reader user may need to move by landmarks, headings, links, and form fields rather than by visual grouping. All of those are valid working methods, and the lesson should support them.
+
+[PAUSE]
+
+[JAMIE]
+You mentioned multiple working styles. That seems to be a broader learning pattern in this course.
+
+[ALEX]
+Yes. One of the learning moments in this chapter is that collaboration tools are not just about the feature set. They are about finding a way of working that fits how you process information and move through interfaces. Some people understand issues best by opening one and reading it top to bottom. Some understand better by scanning the list first, noticing patterns in titles and labels, and then opening a few examples. Some want to work entirely in the browser. Others prefer local tools.
+
+[JAMIE]
+That is where the learning cards idea comes in, right? Different paths for different learners.
+
+[ALEX]
+Exactly. Think of the learning cards as multiple valid ways to practice the same outcome. One learner might follow the browser path closely and focus on visual navigation. Another might lean into keyboard access and screen-reader structure. Another might prefer local Git or the GitHub CLI because command-line workflows are easier for them to repeat and reason about.
+
+[JAMIE]
+Let us say more about that last group, because a lot of people are surprised that issues are not browser-only.
+
+[ALEX]
+Right. The lesson centers the GitHub interface, because that is the most universal entry point, but there is also a local Git and GitHub CLI alternative. Local Git itself does not manage issues as a core feature, but the GitHub CLI can. If you already work comfortably in a terminal, you can view, create, and comment on issues there. That can be useful for keyboard-focused workflows, automation, or just personal preference.
+
+[JAMIE]
+So the principle stays the same even if the interface changes.
+
+[ALEX]
+Exactly. Whether you create the issue in the web UI or through the GitHub CLI, the same standards apply. The title still needs to be clear. The body still needs context and evidence. Comments still carry the collaboration forward. Mentions still matter because they notify the right people.
+
+[PAUSE]
+
+[JAMIE]
+I want to go back to the issue list one more time, because it is easy to underestimate how much information is packed into that page. What should learners actively practice noticing?
+
+[ALEX]
+Notice the status first: open or closed. Then notice the title and whether it sounds like your topic. Then check the supporting details: labels, number of comments, who opened it, and any clues about scope or urgency. If you are using search and filters, practice narrowing the list before opening items at random. That is a real project skill. It saves time and prevents duplicate reporting.
+
+[JAMIE]
+And if someone is using a screen reader, that same skill becomes listen for the signals that help you choose the right issue.
+
+[ALEX]
+Exactly. Instead of visually skimming rows, you are listening for the row details that tell you whether to open that issue. It is the same decision process, just through a different access method.
+
+[JAMIE]
+What about low-vision users on a busy issue page?
+
+[ALEX]
+Use the browser tools that make the page readable to you. Zoom in. Increase text size. Use your preferred contrast settings. If the page becomes visually crowded, move section by section instead of trying to hold the full layout in view. The issue title, issue body, comments, and metadata are all meaningful, but you do not need to absorb them at once.
+
+[PAUSE]
+
+[ALEX]
+Here is the deeper learning pattern underneath all of this: collaboration works better when information is discoverable, specific, and shared in the place where future work will happen. That is why issues matter. They reduce ambiguity. They make conversations durable. They help teams coordinate across time.
+
+[JAMIE]
+And that is also why the writing quality matters more than people think.
+
+[ALEX]
+Yes. A vague issue costs everyone time. A clear issue invites useful action. This is not about sounding formal. It is about making the work legible to other people.
+
+[JAMIE]
+That is a good workshop sentence: make the work legible.
+
+[ALEX]
+It applies everywhere. Good issue titles make the list legible. Good issue bodies make the task legible. Good comments make decisions legible. Mentions make responsibility legible. Evidence makes progress legible.
+
+[PAUSE]
+
+[JAMIE]
+If someone completes this chapter and still feels awkward using issues, should they worry?
+
+[ALEX]
+No. The goal is familiarity, not fluency in one session. If you can find the Issues tab, understand the list page, create a reasonable issue, add a comment, use a mention when appropriate, and explain what you did, you are on track. The rest comes from repetition.
+
+[JAMIE]
+And repetition can happen in different styles.
+
+[ALEX]
+Exactly. You might practice in the browser. You might practice with the GitHub CLI. You might focus on keyboard navigation one day and on writing clearer issue bodies the next. Those are all valid ways to build the skill.
+
+[JAMIE]
+One last practical question. If a learner is unsure whether to open an issue, what should guide the decision?
+
+[ALEX]
+Ask whether the work would benefit from a shared record. If the answer is yes, an issue is probably a good fit. If the topic needs context, follow-up, or visibility, an issue helps. If it is just a private note to yourself and no collaboration is needed, maybe not. But in most project settings, making work visible is a strength, not a burden.
+
+[PAUSE]
+
+[ALEX]
+So, as you move through the exercise, keep the shape of the lesson in mind. Find the Issues area. Learn the page enough to orient yourself. Read the issue rows for meaning, not just titles. Use search and filters before creating something new. Write a title that tells the truth about the work. Write a body that gives context and evidence. Use comments to keep the collaboration in the open. Use @mentions to bring in the right person when needed. Treat sub-issues as optional structure for larger work. Capture evidence of what you did. And if you hit friction, use the recovery steps instead of assuming you are failing.
+
+[JAMIE]
+That is a much calmer way to approach it.
+
+[ALEX]
+That is the point. GitHub Issues are not a test of whether you already know how teams work. They are one of the tools teams use to learn how to work together.
+
+[JAMIE]
+And if you can leave a clear trail for the next person, you are already doing meaningful collaboration.
+
+[ALEX]
+Exactly. That is the lesson.

+  "transcriptText": "[ALEX]\nWelcome back to Git Going with GitHub. This is episode 5: Working with Issues. I am Alex, and today we are turning Working with Issues from a list of instructions into a working mental model.\n\n[JAMIE]\nAnd I am Jamie. I will stop us whenever the instructions sound simple on paper but might feel different with a keyboard and screen reader.\n\n[PAUSE]\n\n[ALEX]\nFiling, searching, filtering, commenting on, and managing GitHub issues. That is the surface description. Underneath it, we are building judgment: where to focus, what to ignore, and how to verify the result.\n\n[JAMIE]\nSo we are not using the audio as a shortcut around learning. We are using it to make the learning easier to enter.\n\n[ALEX]\nYes. A good audio lesson gives someone enough context to try the work with confidence, even before they open the written material.\n\n[PAUSE]\n\n[JAMIE]\nOkay, set the room for us. What are we walking into?\n\n[ALEX]\nFiling, Managing, and Participating in GitHub Issues: Issues are where open source collaboration begins. The next useful detail is concrete: everything from finding the right issue to file a perfect bug report - all with your keyboard and screen reader.\n\n[ALEX]\nA solid issue habit is to read the title, the body, and the timeline before acting. You are listening for the requested action, the missing evidence, and the person who needs a response.\n\n[ALEX]\nThe next layer is this. Here is the learner-facing version. Chapter 5 is the first issue-based challenge chapter with short, confidence-building tasks. Put another way, it supports Challenge 2 (File Your First Issue) and Challenge 3 (Join the Conversation). A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[ALEX]\nHere are the anchors worth keeping. There are 2 core challenges plus one optional extension. Each challenge should take under 10 minutes. The evidence is issue comments and issue metadata. The pattern is claim - act - confirm.\n\n[JAMIE]\nWhat does the learner do first, second, and then after that?\n\n[ALEX]\nThis is the move inside Chapter 5 Challenge Set: chapter 5 focuses on issue skills. That matters in practice: You do NOT need to create a branch or edit any files for these challenges.\n\n[ALEX]\nWalk it in order: Create your first issue - file a new issue with a clear title and description; Comment and @mention - leave a comment on a classmate's issue and tag them with an @mention; and Optional extension: Add a sub-issue - break a larger issue into smaller, trackable pieces if your repository has sub-issues enabled. Each step should leave a trace you can name.\n\n[JAMIE]\nThat feels much more doable when you say it as one move.\n\n[ALEX]\nRight. The magic is not speed. The magic is knowing what changed and why it matters.\n\n[PAUSE]\n\n[JAMIE]\nTurn that into a path someone can follow.\n\n[ALEX]\nAnchor this part on Challenge 2 Step-by-Step: Create Your First Issue. File a new issue in your Learning Room repository with a specific title and a meaningful description. This is the part to say slowly: Issues are the prompts that wake up AI.\n\n[ALEX]\nFor a learner, the useful signals are concrete. \"Agent Request: Add missing contributor background paragraph in welcome.md\". \"Keyboard shortcuts table has incorrect NVDA modifier key\". \"Setup guide link to accessibility settings is broken\". What the problem is or what content is missing.\n\n[ALEX]\nThink of this as 4 checks: Open your Learning Room repository in your browser; Navigate to the Issues tab (press G then I to jump there with keyboard shortcuts, or find the \"Issues\" link in the repository navigation); Activate the New issue button; and If a template picker appears, select Open a blank issue (or choose a template if one fits). If one step does not match what you hear, stop there and re-orient.\n\n[JAMIE]\nWhat is the ordered workflow?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is in the Title field, type a clear, specific title (at least 12 characters). Step two is in the Body field, write a meaningful description (at least 80 characters). Step three is activate Submit new issue. Step four is copy the issue URL or note the issue number (for example, 150). You will reference this later. That is the rhythm: orient, act, verify, continue.\n\n[JAMIE]\nGive me the sequence, because order matters here.\n\n[ALEX]\nThe reason this matters is simple: leave a comment on another student's issue and use an @mention to notify them. The listener should be able to check this: the Issues tab of your Learning Room repository on GitHub.com.\n\n[ALEX]\nThe parts worth keeping in working memory are these. \"@classmate I can confirm this - the link in setup-guide.md goes to a 404 page.\". \"@classmate Good catch! I think the correct shortcut is Insert+F7, not Insert+F5.\". \"@classmate I'd suggest adding the paragraph right after the 'Who Can Contribute' heading.\".\n\n[ALEX]\nThe path is straightforward once it is named. Step one is open the Issues tab in your Learning Room repository. Step two is find an issue created by a classmate (look for recent open issues, or use a facilitator-provided peer-simulation issue). Step three is open the issue by activating its title link. Step four is read the issue description to understand what they reported. That is the rhythm: orient, act, verify, continue.\n\n[JAMIE]\nHow would you walk the room through that step by step?\n\n[ALEX]\nFirst, scroll to the comment box at the bottom of the issue. Then, write a helpful comment that @mentions the issue author by username. After that, activate the Comment button (or press Ctrl+Enter). That small check between steps is what makes the workflow reliable.\n\n[ALEX]\nThe useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.\n\n[JAMIE]\nLet's pause on Optional Extension Step-by-Step: Add a Sub-Issue. What should a learner take away from it?\n\n[ALEX]\nDo not treat Optional Extension Step-by-Step: Add a Sub-Issue as decoration. Break a larger issue into smaller, trackable pieces using GitHub's sub-issue feature. That is not trivia. the issue you created in Challenge 2 (or any open issue you have permission to edit). The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[ALEX]\nOn the ground, that means a few things. Sub-issue: \"Add alt text to welcome banner image\". Sub-issue: \"Fix heading hierarchy in Getting Started section\".\n\n[ALEX]\nFirst, open the issue you created in Challenge 2. Then, look for the Sub-issues section in the issue sidebar (right side on desktop). If you do not see it, look for an Add sub-issue button or the Create sub-issue option below the issue description. After that, activate Add sub-issue and choose Create new sub-issue. Finally, give the sub-issue a clear title that describes one specific piece of the parent issue. For example, if the parent is \"Fix accessibility in welcome.md\". That small check between steps is what makes the workflow reliable.\n\n[JAMIE]\nBefore we leave Optional Extension Step-by-Step: Add a Sub-Issue, what is the practical point?\n\n[ALEX]\nStart here: Add a short description and activate Create. Then: The sub-issue now appears nested under the parent issue with a progress indicator. The sequence works because every action has a confirmation.\n\n[PAUSE]\n\n[JAMIE]\nWhat should the learner prove to themselves after each small task?\n\n[ALEX]\nIf the interface shifts, Completing Chapter 5: Submit Your Evidence is still useful because when you have finished the Chapter 5 issue challenges, go to your assigned Challenge 2 or Challenge 3 issue and post a comment with your evidence. For someone navigating by keyboard or screen reader, this detail matters: Replace [number] with the actual issue numbers.\n\n[ALEX]\nThis is where the talk moves from concept to action. Expected Outcomes has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThe room should hear these as checkpoints. Student can create an issue with a clear title and description. Student can communicate in issue threads using @mentions. Student can organize work by breaking issues into sub-issues.\n\n[JAMIE]\nNow it sounds like a workflow instead of a wall of instructions.\n\n[ALEX]\nThat is where confidence comes from: not from never getting lost, but from knowing how to recover.\n\n[JAMIE]\nLet's pause on If You Get Stuck. What should a learner take away from it?\n\n[ALEX]\nIf You Get Stuck has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThink of this as 4 checks: Can't find a classmate's issue? Filter the Issues tab by is:open and look for recent ones; @mention not working? Make sure you type @ immediately followed by the username with no space; Sub-issue option not visible? Ask a facilitator - the feature may need to be enabled for the repository; and Still stuck? Ask a facilitator for a direct issue link. Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave If You Get Stuck, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is finished but not sure you did it right? Compare your work against the Challenge 2 reference solution or the Challenge 3 reference solution. The point is not speed; the point is never losing your place.\n\n[PAUSE]\n\n[ALEX]\nBefore the learner moves on. This part earns its place because issues are collaborative spaces, not just task lists. That gives the learner a foothold: an @mention tells someone \"I need your attention here.\" Sub-issues turn vague tasks into clear checklists. That is the difference between following directions and owning the workflow.\n\n[JAMIE]\nLet's pause on Learning Pattern Used in This Chapter. What should a learner take away from it?\n\n[ALEX]\nLearning Pattern Used in This Chapter has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nFirst, start with a small, safe action (create an issue). Then, practice communication in public issue threads (@mention a peer). After that, organize work into smaller pieces (sub-issues). Finally, leave clear evidence in the issue timeline. Each step should leave a trace you can name.\n\n[JAMIE]\nBefore we leave Learning Pattern Used in This Chapter, what is the practical point?\n\n[ALEX]\nStart here: Build momentum for file editing and PR work in Chapter 6. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nNow slow down for the part people usually miss. Here is the learner-facing version. This chapter provides learning cards: expandable blocks that offer perspective-specific guidance for different ways of working. Put another way, not every card appears at every step.\n\n[PAUSE]\n\n[JAMIE]\nWhat should they understand before typing anything?\n\n[ALEX]\nThis is the move inside Local Git Alternative: Working from Your Clone: if you cloned the learning-room in Block 0 and prefer working locally. That matters in practice: During Block 0 you cloned the Learning Room repository to your computer.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like cd /Documents/learning-room or wherever you cloned it; git status should show \"On branch main\". List your assigned challenge issues; gh issue list --assignee @me --label challenge; View a specific issue in the terminal; gh issue view 42; Leave a comment on an issue; gh issue comment 42 --body \"I'd like to try this!\"; Create a new issue interactively; gh. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nThat is the kind of detail that keeps a screen reader user oriented.\n\n[ALEX]\nYes. The named thing - the heading, tab, field, branch, or button - is the handhold.\n\n[ALEX]\nA solid Git habit is to know which branch you are on, what changed, and what confirmation you expect before you run the next command.\n\n[ALEX]\nHere is the moment where the page starts to make sense. Anchor this part on What Is a GitHub Issue? An issue is a discussion thread attached to a repository. This is the part to say slowly: Every issue has a number ( 42), a state (Open or Closed), a title, a description, and a comment thread. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[ALEX]\nListen for the small confirmations in this list. Bug reports - \"This feature doesn't work when using a screen reader\". Feature requests - \"It would help if the submit button had an accessible label\". Questions - \"How do I configure X for Y use case?\". Tasks - \"Update the README with screen reader instructions\".\n\n[JAMIE]\nLet's pause on From a repository page. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: click the Issues tab in the repository navigation bar below the repository name. The listener should be able to check this: The tab shows the open issue count (e.g., \"Issues · 14\").\n\n[ALEX]\nThe path is straightforward once it is named. Step one is press D to navigate to the \"Repository navigation\" landmark. Step two is press K or Tab to move through the tab links. Step three is find \"Issues\" - it will be announced with the count: \"Issues, 14 open\". Step four is press Enter to open the Issues tab. The sequence works because every action has a confirmation.\n\n[JAMIE]\nBefore we leave From a repository page, what is the practical point?\n\n[ALEX]\nFirst, vO+U → Landmarks → navigate to \"Repository navigation\". Then, vO+Right or Quick Nav K to move through tab links. After that, find \"Issues\" - VoiceOver announces the count: \"Issues 14\". Finally, vO+Space to activate the Issues tab. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like gh issue list. gh issue list --label \"good first issue\"; gh issue list --assignee @me; gh issue list --state closed. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[ALEX]\nThe next point gives the learner a handle. Do not treat Direct URL as decoration. Navigate directly: https://github.com/[owner]/[repo]/issues.\n\n[JAMIE]\nWhat would you say to someone who is already bracing for this to be too much?\n\n[ALEX]\nLearning Cards: Navigating to the Issues List has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nA few details make that real. Press D to jump to the \"Repository navigation\" landmark, then K or Tab to find the Issues link -- this is faster than arrowing through the entire page. The Issues tab announces its open count (\"Issues, 14 open\"), giving you an instant sense of project activity without loading the list. Use gh issue list in the terminal to bypass browser navigation entirely; pipe through --label or --assignee @me to pre-filter results. The Issues tab count badge may be small at default zoom; at 200%+ the tab text reflows but the count remains visible next to the word \"Issues\". Bookmark the direct URL pattern (github.com/owner/repo/issues) to skip repository page navigation altogether. In high-contrast mode, the active tab is indicated with an underline using system highlight color, not just a subtle background change.\n\n[ALEX]\nHold that next to this. Put Page structure into plain language. Quick orientation tip: Press NVDA+F7 (or VO+U on macOS) to open a list of all headings, links, form fields, and buttons on the page. The useful version is: This is often faster than tabbing through many elements and helps you understand the full page structure before diving in. The interface gets easier when it becomes a set of named places instead of a wall of controls.\n\n[JAMIE]\nSo the learner is not behind if they stop there and check the page.\n\n[ALEX]\nYes. Pausing to verify is not a detour; it is how you keep control of the workflow.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on How to read the issue list. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. The issues list shows each issue as a row with its title, labels, number, assignee avatars, and comment count. That is the difference between guessing and knowing: Closed issues show a purple merged/closed badge.\n\n[ALEX]\nThat shows up in the workshop in a few specific ways. Issue titles are the largest text in each row and remain readable at 200%+ zoom. Label badges use colored backgrounds with text inside. In Windows High Contrast mode, labels display with system border colors and readable text rather than colored backgrounds. The Open and Closed toggle links above the list let you switch views. The active toggle is bold or underlined. The comment count icon (a speech bubble) may be small at high zoom. It appears to the right of each issue row. Hover to see \"N comments\" tooltip.\n\n[ALEX]\nThink of this as 4 checks: Press D to reach the \"Search Results List\" landmark; Press 3 (h3) to navigate by issue titles - each issue title is an h3 link; Press I to move between list items if you want more detail per item; and Press Enter on a title to open that issue. Each step should leave a trace you can name.\n\n[JAMIE]\nBefore we leave How to read the issue list, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is vO+U → Landmarks → navigate to \"Search Results List\". Step two is vO+Down to read through items. Step three is h (with Quick Nav on) or VO+U → Headings to jump by issue title. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nThat connects to another useful point. This part earns its place because when you navigate to an issue in the list, your screen reader will announce (in some order).\n\n[ALEX]\nHere is what that changes in practice. Issue title (as a link). Issue number ( 42). Labels (e.g., \"bug, good first issue\"). Who opened it and when (\"Opened 3 days ago by username\"). Number of comments (\"5 comments\").\n\n[JAMIE]\nWhat is the one idea that makes the next few steps less mysterious?\n\n[ALEX]\nLearning Cards: The Issues List Page has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThese are the details that keep the idea from floating away. Press D to jump to the \"Search Results List\" landmark, then press 3 to navigate issue titles (each is an H3 link). Press I to move between individual list items if you want full detail per issue (number, labels, author, age). After applying a filter, the issue list updates silently; press 3 again to re-navigate the updated list from the top. Issue titles are the largest text per row and stay readable at 200%+ zoom; labels appear as small colored badges to the right of each title. The Open/Closed toggle links are near the top of the list; the active state is bold or underlined depending on your theme. If the comment count icon (speech bubble) is too small at your zoom level, hover over it for a tooltip showing the exact count.\n\n[PAUSE]\n\n[ALEX]\nHere is the practical turn. Here is the learner-facing version. Filtering lets you narrow the list to find the right issue quickly. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[JAMIE]\nLet's pause on Using the search/filter bar. What should a learner take away from it?\n\n[ALEX]\nUsing the search/filter bar has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nWalk it in order: Press F or E to jump to the filter input field (or navigate from the landmark); Switch to Focus Mode (NVDA+Space / Insert+Z) if not already in it; Type your filter or search query; and Press Enter to apply. The sequence works because every action has a confirmation.\n\n[JAMIE]\nThat is a useful checkpoint before anyone starts pressing keys.\n\n[ALEX]\nExactly. Checkpoints turn uncertainty into information.\n\n[JAMIE]\nLet's pause on Using the filter buttons. What should a learner take away from it?\n\n[ALEX]\nAnchor this part on Using the filter buttons. Above the issue list, there is an actions toolbar with filter buttons for Labels, Milestones, Assignees, etc. This is the part to say slowly: The filter buttons do not indicate the current filter state.\n\n[ALEX]\nThat becomes easier when you listen for these cues. The Label, Milestone, and Assignee buttons may wrap to a second row. Each button opens a dropdown with searchable options. Dropdown menus from filter buttons can extend below the visible viewport at high zoom. Scroll within the dropdown to see all options. Type in the search field at the top of each dropdown to narrow the list (for example, type \"accessibility\" in the Label dropdown). In Windows High Contrast mode, the selected filter values are indicated with a checkmark icon and system highlight color, not just a background color change.\n\n[ALEX]\nThink of this as 4 checks: Press Tab from the search bar (or Shift+Tab from the issue list) to reach the actions toolbar; Press ←/→ to move between toolbar options (Label, Milestone, Assignee, Sort); Press Enter to open the selected dropdown; and Use ↑/↓ to navigate options in the dropdown. Keep it that plain: know where you are, make the move, check the result.\n\n[JAMIE]\nBefore we leave Using the filter buttons, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is press Enter or Space to select. Step two is press Escape to close (filter applies immediately). Step three is tab forward from the search bar to reach the filter buttons, or use Quick Nav to find them. Step four is vO+Left/Right to move between Label, Milestone, Assignee, Sort buttons. Pause after each step and listen for the confirmation before moving on.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Filter by label; gh issue list --label \"accessibility\"; Combine filters; gh issue list --label \"good first issue\" --assignee @me; Filter by milestone; gh issue list --milestone \"Hackathon Day 1\"; Search with keywords; gh issue list --search \"screen reader\". Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[JAMIE]\nIf I am listening before the workshop starts, what should settle in my mind first?\n\n[ALEX]\nThe reason this matters is simple: the two state links \"Open\" and \"Closed\" appear near the top of the issue list. The listener should be able to check this: Press K to navigate links until you find them, or look for them as buttons near the search bar.\n\n[ALEX]\nAnother way to ground it. Learning Cards: Filtering and Searching Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nIf someone is taking notes, this is the short list. Switch to Focus Mode (NVDA+Space) before typing in the filter bar; switch back to Browse Mode after pressing Enter to read the filtered results. The filter bar does not announce how many results remain after filtering; press H to jump to the issue list heading, then listen for the count in the heading text. Combine gh issue list flags (e.g., --label \"accessibility\" --assignee @me) for instant filtered results without navigating dropdown menus. Filter dropdown menus can extend below the viewport at high zoom; scroll within the dropdown or type in the search field at the top of each dropdown to narrow options. After applying a filter, verify it took effect by checking the search bar text -- it updates to show active conditions like is:open label:accessibility. The Ctrl+/ (Windows) or Cmd+/ (Mac) shortcut focuses the search bar instantly, avoiding the need to scroll up to find it.\n\n[JAMIE]\nWhere do you want a learner to place their attention here?\n\n[ALEX]\nIf the interface shifts, Landing on an issue page is still useful because when you open an issue, the page structure is.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Reading the issue description. What should a learner take away from it?\n\n[ALEX]\nPut Reading the issue description into plain language. Browse Mode recommended: The issue detail page is primarily text-based. The useful version is: Stay in Browse Mode (not Focus Mode) for reading - it gives you full heading (H), section (D), and link (K) navigation throughout the page.\n\n[ALEX]\nWalk it in order: Press 2 to reach the \"Description\" heading; Press ↓ to read the content line by line,; and Use NVDA+↓ (NVDA say all) to have it read continuously. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like View issue in terminal (renders Markdown); gh issue view 42; Open the issue in your browser instead; gh issue view 42 --web; View just the comments; gh issue view 42 --comments. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nI like that because it gives people permission to slow down.\n\n[ALEX]\nThat is the goal. We want the page to feel explorable, not fragile.\n\n[JAMIE]\nGive me the version that sounds like an instructor, not a manual.\n\n[ALEX]\nThe teaching point here is not the label; it is the move. Each comment in the thread is marked as an h3. That is the difference between guessing and knowing: Other timeline events (label added, PR linked, issue closed) appear between comments in the activity stream.\n\n[ALEX]\nThese are the pieces that turn the idea into a usable move. Commenter's username. Timestamp (\"2 days ago\"). Body text. Reactions (if any - announced as a button with an emoji and count).\n\n[ALEX]\nPut that beside the next piece. Learning Cards: Reading an Issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThe useful version is not abstract; it sounds like this. Press 1 to hear the issue title, then 2 to reach \"Description\" and \"Activity\" headings, and 3 to jump between individual comments. Stay in Browse Mode for reading; only switch to Focus Mode (NVDA+Space) when you need to type in the comment box. Press D to jump to the \"Add a comment\" landmark at the bottom of the page to skip directly to the reply area. The issue title is the largest text on the page, followed by an Open/Closed badge in green or purple. Comment blocks have a subtle border and a grey header bar showing the author's avatar and timestamp; zoom in on the header to identify commenters. The sidebar (Labels, Assignees, Milestone) is on the right at desktop width; at high zoom it may move below the main content.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Step-by-step. What should a learner take away from it?\n\n[ALEX]\nStep-by-step: To close the issue while commenting: click the arrow on the Close issue button and choose Close with comment. The next useful detail is concrete: Low vision users (zoom, high contrast).\n\n[ALEX]\nFirst, scroll to the bottom of the issue page. Then, click in the Leave a comment text area. After that, type your comment (Markdown is supported - use the toolbar buttons above the text for bold, italic, code, etc.). Finally, optionally click Preview to see how it will render. The sequence works because every action has a confirmation.\n\n[JAMIE]\nBefore we leave Step-by-step, what is the practical point?\n\n[ALEX]\nStart here: Click the green Comment button to post. Then: Scroll to the bottom to find the Leave a comment text area. At 200%+ zoom, this may require significant scrolling past the timeline. Next: The text area expands as you type. The formatting toolbar above it (bold, italic, code, etc.) wraps at high zoom but remains functional. Last: The Preview tab next to Write lets you check Markdown rendering before posting. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Interactive: opens your default editor ($EDITOR) to write the comment; gh issue comment 42; Inline: provide the comment text directly; gh issue comment 42 --body \"Thanks for reporting this. I can reproduce the issue with NVDA + Chrome.\". Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[ALEX]\nNow shift from knowing the term to using it. Here is the learner-facing version. These keyboard shortcuts work inside the text area (Focus Mode).\n\n[JAMIE]\nLet's pause on GitHub shortcuts for the Issues pages. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside GitHub shortcuts for the Issues pages: these are the GitHub built-in shortcuts for working with issues. That matters in practice: Enable Focus Mode first (NVDA: NVDA+Space, JAWS: Insert+Z) before using single-key shortcuts.\n\n[JAMIE]\nThat is the part I would want someone to say out loud while they work.\n\n[ALEX]\nExactly. A learner should always know what they are trying to prove before they take the next action.\n\n[PAUSE]\n\n[ALEX]\nThis is where confidence starts to build. Anchor this part on On the Issues list page. Shortcut note: For G I, press G, release it, then press I (two sequential key presses, not simultaneous). The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[JAMIE]\nLet's pause on On an open issue. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: r to quote is a power move: Select any text in a comment while in Browse Mode (Shift+Arrow to select), then press R. The listener should be able to check this: GitHub puts the quoted text in the comment box as a Markdown blockquote.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is navigate to your comment (3 to jump to comments). Step two is find the \".\" (ellipsis) menu button near your comment. Step three is press Enter on \"Edit\" from that menu. Step four is the comment turns into a text area - switch to Focus Mode. Each step should leave a trace you can name.\n\n[JAMIE]\nBefore we leave On an open issue, what is the practical point?\n\n[ALEX]\nFirst, make your changes. Then, tab to \"Update comment\" button → Enter. If one step does not match what you hear, stop there and re-orient.\n\n[ALEX]\nNow bring the learner back to the room. Learning Cards: Leaving a Comment has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part that makes the next action easier. Press D to jump to the \"Add a comment\" landmark, which places focus near the text area; then Enter Focus Mode to start typing. Use Ctrl+Enter to submit your comment directly from inside the text area -- this avoids having to Tab through the formatting toolbar to find the Comment button. To quote someone's text in your reply, select the text in Browse Mode (Shift+Arrow), then press R; GitHub inserts it as a blockquote in the comment box automatically. The comment text area expands as you type and is full-width at high zoom, making it easy to target; use Ctrl+Enter to submit without hunting for the Comment button. Use the Preview tab next to Write to check your Markdown formatting in rendered form before posting; bold, code blocks, and links are much easier to proofread there. Keyboard formatting shortcuts (Ctrl+B for bold, Ctrl+E for inline code) work inside the text area and save time over clicking small toolbar icons.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Navigating to New Issue. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, Navigating to New Issue is still useful because from the Issues list page, click the green New issue button in the top-right of the issue list. For someone navigating by keyboard or screen reader, this detail matters: If the repository has templates, a template picker page appears - click Get started next to the template that fits your needs, or click Open a blank issue to skip templates.\n\n[ALEX]\nThis is where the lesson becomes something you can check. At 200%+ zoom, the button may move below the search bar or wrap to its own line. It remains a prominent green button. If the repository has issue templates, a template picker page appears with each template as a card. Template descriptions may truncate at high zoom. Hover over a truncated description for the full text. The Get started button next to each template is small but uses standard link styling. Press Tab to move between templates and their Get started buttons. Open a blank issue link appears at the bottom of the template list. At high zoom, scroll down to find it.\n\n[ALEX]\nStart here: Press K to navigate links and find the \"New issue\" button/link. Then: Press Enter. Next: If a template picker appears: press 3 to navigate template names, read the description below each, then press Enter on \"Get started\" for the right template - or find \"Open a blank issue.\" link if no template fits. Last: Quick Nav B or VO+U → Buttons to find the \"New issue\" button. That is the rhythm: orient, act, verify, continue.\n\n[JAMIE]\nBefore we leave Navigating to New Issue, what is the practical point?\n\n[ALEX]\nWalk it in order: VO+Space to activate it; and If a template picker appears: Quick Nav H or VO+Cmd+H to navigate template names, then VO+Space on \"Get started\" for the right template - or Quick Nav K to find the \"Open a blank issue\" link. That small check between steps is what makes the workflow reliable.\n\n[ALEX]\nThat matters because of the next idea. Put Filling Out the Issue Form into plain language. The issue form has these fields (order may vary depending on the template). The interface gets easier when it becomes a set of named places instead of a wall of controls.\n\n[JAMIE]\nSo this is less about memorizing and more about noticing.\n\n[ALEX]\nRight. Once the learner can name the move, the interface becomes much less intimidating.\n\n[JAMIE]\nLet's pause on Title field. What should a learner take away from it?\n\n[ALEX]\nTitle field has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThink of this as 4 checks: Find the Title input field (F or by landmark); Focus Mode → type a clear, specific title; Good title: \"Screen reader announces wrong element count on Issues list with 50+ items\"; and Bad title: \"Bug with screen reader\". The sequence works because every action has a confirmation.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Description / Body field. What should a learner take away from it?\n\n[ALEX]\nDescription / Body field has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is tab to the body text area. Step two is focus Mode → type using the Markdown template provided. Step three is if no template, use this structure. Keep it that plain: know where you are, make the move, check the result.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like What happened; Describe what you observed.; What I expected; Describe what should have happened.; How to reproduce; 1. Step one; 2. Step two; 3. Step three; Environment; - Screen reader: [NVDA 2025.3.3 / JAWS 2026 / VoiceOver macOS Sonoma]; - Browser: [Chrome. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Assigning labels from the sidebar. What should a learner take away from it?\n\n[ALEX]\nAssigning labels from the sidebar: See also: Chapter 09: Labels, Milestones, and Projects covers the full label and milestone system. The next useful detail is concrete: While the form is open, the sidebar has dropdowns for Labels, Assignees, and Milestone.\n\n[ALEX]\nFirst, tab away from the text area (or press Escape to leave Focus Mode). Then, navigate to the sidebar - press H to find \"Labels\" heading. After that, press Enter on the Labels gear/button. Finally, dropdown opens → ↑/↓ to navigate labels. Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave Assigning labels from the sidebar, what is the practical point?\n\n[ALEX]\nStart here: Enter to select/deselect. Then: Escape to close (selections save automatically). Next: VO+Shift+Up to stop interacting with the text area. Last: VO+U → Headings to find the \"Labels\" heading in the sidebar. The point is not speed; the point is never losing your place.\n\n[ALEX]\nA solid project habit is to treat metadata as decision support. Labels, status, assignees, and notifications tell you what kind of attention the work needs.\n\n[JAMIE]\nLet's pause on Submitting the issue. What should a learner take away from it?\n\n[ALEX]\nHere is the learner-facing version. GitHub CLI (gh) alternative - filing a new issue. Put another way, create an issue from your terminal. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[ALEX]\nStart here: Tab to \"Submit new issue\" button. Then: Press Enter. The point is not speed; the point is never losing your place.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Interactive: prompts for title, body, labels, and assignees; gh issue create; Inline: provide everything on the command line; gh issue create --title \"Screen reader announces wrong count on Issues list\" \\; --body \" What happened\\n\\nThe count says 14 but only. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Learning Cards: Filing a New Issue. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Filing a New Issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. After pressing \"New issue,\" if a template picker appears, press 3 to jump between template names; each has a \"Get started\" link next to it. In the title field, type at least 12 characters for a meaningful title; press Tab to move to the body field. Press Ctrl+Enter from inside the body text area to submit the issue without needing to find the Submit button. The green \"New issue\" button is in the top-right of the Issues list page; at 200%+ zoom it may wrap below the search bar. Template cards (if the repo uses them) show truncated descriptions at high zoom; hover over them for the full text. The sidebar dropdowns for Labels, Assignees, and Milestone are gear icons that may be small at high zoom; they open searchable dropdown panels.\n\n[JAMIE]\nLet's pause on Tool Cards: File a New Issue. What should a learner take away from it?\n\n[ALEX]\nAnchor this part on Tool Cards: File a New Issue. github.dev (web editor): Not available -- issues are managed through the repository's Issues tab, not the code editor. This is the part to say slowly: VS Code Desktop (GitHub Pull Requests extension).\n\n[ALEX]\nThink of this as 4 checks: Navigate to the repository's Issues tab (or press G then I); Click New issue, choose a template or blank issue; Fill in the title and description, then click Submit new issue; and Open the GitHub panel in the sidebar. If one step does not match what you hear, stop there and re-orient.\n\n[JAMIE]\nBefore we leave Tool Cards: File a New Issue, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is under Issues, click the + icon to create a new issue. Step two is fill in the title and body, then click Create. That is the rhythm: orient, act, verify, continue.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like gh issue create --title \"Your title\" --body \"Description here\"; Or interactively:; gh issue create. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Cross-Referencing Issues. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: linking issues and PRs to each other creates a trail of context that helps everyone understand the project's history.\n\n[PAUSE]\n\n[ALEX]\nKeep the thread going. Do not treat Closing keywords in PR descriptions or issue comments as decoration. When you type these phrases in a PR description or comment (followed by an issue number), GitHub creates a connection. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[JAMIE]\nLet's pause on Mentioning another issue in a comment. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, Mentioning another issue in a comment is still useful because simply type followed by a number anywhere in a comment body. For someone navigating by keyboard or screen reader, this detail matters: GitHub autocompletes with a dropdown of matching issues and PRs.\n\n[ALEX]\nThis is the part worth saying out loud. Put Cross-repo references into plain language. owner/repo 42 - references issue 42 in a different repository.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Learning Cards: Cross-Referencing Issues. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Cross-Referencing Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Type in any comment body to trigger GitHub's autocomplete dropdown; press Down Arrow to browse matching issues and Enter to insert the reference link. Use Closes 42 (not just 42) in PR descriptions so GitHub automatically closes the issue on merge; your screen reader will confirm the link is created in the PR timeline. Cross-references appear as timeline events on the linked issue; navigate with H to find \"mentioned this issue\" entries to trace the conversation history. Cross-reference links ( 42) render as colored, clickable links in both issue bodies and PR descriptions; at high zoom they remain inline with surrounding text. The autocomplete dropdown triggered by may overlap content at high magnification; type additional digits to narrow results and reduce dropdown size. Back-links appear automatically on the referenced issue's timeline, so you can verify the connection was created by visiting either side.\n\n[ALEX]\nKeep the teaching thread moving. This part earns its place because sub-issues (released 2025) let you nest issues inside a parent issue to break large work into tracked pieces. That gives the learner a foothold: a \"parent\" issue contains a list of child issues; each child is a full issue with its own discussion, labels, and assignees. That is the difference between following directions and owning the workflow.\n\n[JAMIE]\nCan you translate that into plain choices?\n\n[ALEX]\nWhen to Use Sub-Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nUse the comparison to make a decision, not to recite a table. The main contrasts are: Large feature broken down means Parent: \"Redesign navigation\"; Children: \"Keyboard nav,\" \"Screen reader nav,\" \"Mobile nav\". Epic tracking means Parent: \"WCAG 2.1 AA compliance\"; Children: one issue per failing criterion. Release milestone means Parent: \"v2.0 release\"; Children: every required PR/fix.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Here is the learner-facing version. The sub-issues section is announced as a region. Put another way, after linking, the child issue appears as a list item with a checkbox showing its open/closed state.\n\n[JAMIE]\nLet's pause on Reading Sub-Issues on a Parent Issue. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside Reading Sub-Issues on a Parent Issue: progress indicator: The parent issue shows a completion bar (e.g., \"3 of 7 completed\") based on how many child issues are closed. That matters in practice: Screen readers announce this as a progress region.\n\n[ALEX]\nKeep the teaching thread moving. Anchor this part on Viewing a Child Issue's Parent. Every child issue shows a \"Parent issue\" link near the top of the page (above the description). This is the part to say slowly: Navigate with H or links (K) to find it. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Sub-Issues vs. Task Lists. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: if you are working on a feature that requires multiple PRs or involves several team members, ask the maintainer to create a parent issue. The listener should be able to check this: You can then claim individual child issues without one person owning the whole feature.\n\n[ALEX]\nKeep the teaching thread moving. Learning Cards: Sub-Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. The sub-issues section is announced as a region; press H to navigate to the \"Sub-issues\" heading, then arrow down through the list where each child announces its checkbox state, title, and open/closed badge. The parent issue shows a progress indicator (\"3 of 7 completed\") announced as a progress region; listen for this after the sub-issues heading to gauge overall status. Every child issue includes a \"Parent issue\" link near the top of its page; navigate with K (links) to find it and jump back to the parent quickly. The completion progress bar on the parent issue uses color to show progress; in high-contrast mode, completed vs. remaining segments use distinct system colors. At high zoom, the \"Add sub-issue\" button may wrap below the sub-issues list; Tab past the last child item to reach it. Each child issue's open/closed badge uses both color and text (\"Open\" or \"Closed\"), so status is readable without relying on color alone.\n\n[JAMIE]\nLet's pause on Closing an issue. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, Closing an issue is still useful because scroll to the bottom of the issue page. For someone navigating by keyboard or screen reader, this detail matters: Click the Close issue button next to the comment box.\n\n[ALEX]\nStart here: Keyboard shortcut (fastest): Navigate to the comment text area (D → \"Add a comment\" landmark), switch to Focus Mode, then press Ctrl+Shift+Enter to close the issue. Then: Button approach: Tab to the \"Close issue\" button (at the bottom of the page, near the comment box) and press Enter. Next: Optionally leave a closing comment first. Last: Keyboard shortcut (fastest): VO+U → Landmarks → \"Add a comment\", interact with the text area (VO+Shift+Down), then press Cmd+Shift+Return to close the issue. Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave Closing an issue, what is the practical point?\n\n[ALEX]\nWalk it in order: Button approach: Quick Nav B or Tab to find the \"Close issue\" button, then VO+Space. The point is not speed; the point is never losing your place.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Close an issue; gh issue close 42; Close with a reason; gh issue close 42 --reason \"completed\"; gh issue close 42 --reason \"not planned\"; Close with a comment; gh issue close 42 --comment \"Fixed in PR 45.\"; Reopen a closed issue; gh issue reopen 42. Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Put Reopening a closed issue into plain language. If an issue is Closed, the \"Close issue\" button becomes \"Reopen issue\" - navigate and activate to reopen. The interface gets easier when it becomes a set of named places instead of a wall of controls.\n\n[JAMIE]\nLet's pause on Assigning an issue. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. GitHub CLI (gh) alternative - assigning and labeling. That is the difference between guessing and knowing: Manage assignments and labels from your terminal.\n\n[ALEX]\nThink of this as 4 checks: Navigate to \"Assignees\" heading (3 or H); Activate the gear/plus button; Type a username in the search field; and Select from the dropdown. Each step should leave a trace you can name.\n\n[ALEX]\nTreat examples as spoken recipes, not decorations. You may hear something like Assign yourself; gh issue edit 42 --add-assignee @me; Add labels; gh issue edit 42 --add-label \"accessibility,in progress\"; Remove a label; gh issue edit 42 --remove-label \"needs triage\"; Set a milestone; gh issue edit 42 --milestone \"Hackathon Day 1\". Read the command, understand what it changes, then run it only when the repository state matches the lesson.\n\n[JAMIE]\nLet's pause on Changing labels. What should a learner take away from it?\n\n[ALEX]\nChanging labels has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is navigate to \"Labels\" heading. Step two is activate the gear button. Step three is select/deselect labels from the dropdown. Step four is press Escape to save. If one step does not match what you hear, stop there and re-orient.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Transferring or deleting an issue. What should a learner take away from it?\n\n[ALEX]\nTransferring or deleting an issue: Available from the \".\" (ellipsis) button at the top of the issue - navigate buttons with B to find it.\n\n[ALEX]\nKeep the teaching thread moving. Learning Cards: Managing Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Close an issue instantly with Ctrl+Shift+Enter from the comment text area (Focus Mode) -- no need to Tab to the Close button. The sidebar sections (Assignees, Labels, Milestone) each have their own heading; press H or 3 to jump between them, then activate the gear icon to open each dropdown. Use gh issue edit 42 --add-label \"accessibility\" --add-assignee @me to batch-update labels and assignments from the terminal without navigating sidebar controls. Sidebar controls (Assignees, Labels, Milestone) are narrow at default width; at high zoom they stack vertically and each dropdown opens a searchable overlay that is easier to read. The Close issue button turns green and its label changes to \"Reopen issue\" once closed; in high-contrast mode, both states use distinct system colors. Type in the search field inside each sidebar dropdown (Labels, Assignees) to filter long lists rather than scrolling through all options at high magnification.\n\n[JAMIE]\nLet's pause on The \"good first issue\" Label - Your Entry Point. What should a learner take away from it?\n\n[ALEX]\nThis is the move inside The \"good first issue\" Label - Your Entry Point: when looking for your first open source contribution. That matters in practice: Remember: It's respectful to ask before starting.\n\n[ALEX]\nWalk it in order: Navigate to any project's Issues tab; Filter by label: type is:open label:\"good first issue\" in the search; Read through issues until you find one in your area of interest; and Comment on the issue: \"Hi, I'd like to work on this. Can I be assigned?\". The sequence works because every action has a confirmation.\n\n[JAMIE]\nBefore we leave The \"good first issue\" Label - Your Entry Point, what is the practical point?\n\n[ALEX]\nThink of this as 1 checks: Wait for a maintainer to respond and assign you before starting work. Keep it that plain: know where you are, make the move, check the result.\n\n[PAUSE]\n\n[ALEX]\nKeep the teaching thread moving. Learning Cards: The \"good first issue\" Label has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Use the filter query is:open label:\"good first issue\" in the search bar to jump directly to beginner-friendly issues; gh issue list --label \"good first issue\" does the same in the terminal. Before claiming an issue, read existing comments to check whether someone else has already been assigned; listen for \"assigned to\" in the sidebar metadata. When you comment to claim an issue, include a sentence about your approach so the maintainer can give early feedback before you start coding. The \"good first issue\" label renders with a distinct background color (typically light purple or teal); in high-contrast mode it uses system highlight colors with readable text. Filter results may include issues with multiple labels stacked together; at high zoom, labels wrap to a second line but remain readable. Bookmark the filtered URL (/issues?q=is:open+label:\"good first issue\") in your browser for one-click access to beginner issues across your favorite repositories.\n\n[JAMIE]\nLet's pause on Accessibility-Specific Issue Writing Tips. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: when filing accessibility bugs, these details help maintainers reproduce and fix the problem.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is screen reader and version - \"NVDA 2025.3.3\" not just \"screen reader\". Step two is oS and version - \"Windows 11 22H2\". Step three is browser and version - \"Chrome 124.0.6367.82\". Step four is GitHub interface - \"Modern experience (default since Jan 2026)\" or \"Classic experience (opted out)\". Pause after each step and listen for the confirmation before moving on.\n\n[JAMIE]\nBefore we leave Accessibility-Specific Issue Writing Tips, what is the practical point?\n\n[ALEX]\nFirst, what was announced - quote the exact text your screen reader spoke. Then, what should have been announced - describe the expected behavior. After that, aRIA issue if known - e.g., \"The button has no accessible name\". Finally, steps to reproduce - numbered, step-by-step. The point is not speed; the point is never losing your place.\n\n[ALEX]\nKeep the teaching thread moving. Example of a well-filed accessibility issue has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Learning Cards: Accessibility-Specific Issue Writing. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Accessibility-Specific Issue Writing has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Always quote the exact text your screen reader announced in the issue body; wrap it in a fenced code block so readers know it is literal output, not your description. Include your screen reader name and version (e.g., \"NVDA 2025.3.3\") plus browser and OS; this lets maintainers reproduce with the same toolchain. Test with a second screen reader or browser if possible and note the results -- \"Also fails in JAWS 2026 with Chrome; works in VoiceOver with Safari\" dramatically narrows the debugging scope. When filing zoom or contrast bugs, state your exact zoom level and whether you use Windows High Contrast, macOS Increase Contrast, or a browser extension. Screenshots are powerful evidence; annotate them (circle the problem area, add a text callout) and always include alt text describing what the screenshot shows. Note whether the issue occurs only at certain zoom levels or viewport widths; a bug at 400% that disappears at 200% points to a CSS breakpoint problem.\n\n[ALEX]\nKeep the teaching thread moving. Put Writing Effective Issues into plain language. See also: Appendix N: Advanced Search covers search qualifiers to find existing issues before filing a new one. The useful version is: A well-written issue saves everyone time -- the maintainer who reads it, the contributor who fixes it, and the future searcher who finds it six months later.\n\n[JAMIE]\nLet's pause on Bug Report Structure. What should a learner take away from it?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. A strong bug report answers five questions. That is the difference between guessing and knowing: Use this template every time you report something broken.\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Feature Request Structure. What should a learner take away from it?\n\n[ALEX]\nThis part earns its place because feature requests work best when they focus on the problem before jumping to the solution. That gives the learner a foothold: a feature request that starts with \"I want a dark mode toggle\" is weaker than one that starts with \"Low-vision users report eyestrain after 20 minutes because the current theme has insufficient contrast.\" The second version gives maintainers something to. That is the difference between following directions and owning the workflow.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is problem statement -- Describe the pain point. What are you trying to do, and why is it hard or impossible right now? Step two is proposed solution -- Your best idea for fixing the problem. Be specific enough to discuss, but hold it loosely. Step three is alternatives considered -- Other approaches you thought about and why they fell short. This shows you have done your homework. Step four is who benefits -- Name the audience. \"Screen reader users navigating large repositories\" is more compelling than \"everyone.\". That small check between steps is what makes the workflow reliable.\n\n[JAMIE]\nLet's pause on General Issue Writing Principles. What should a learner take away from it?\n\n[ALEX]\nGeneral Issue Writing Principles: These rules apply to every issue -- bugs, features, questions, and everything in between. The next useful detail is concrete: If you discovered two bugs during the same session, file two separate issues.\n\n[ALEX]\nKeep the teaching thread moving. Here is the learner-facing version. I tried clicking and nothing happened. Put another way, the maintainer has to ask: What doesn't work?\n\n[PAUSE]\n\n[JAMIE]\nLet's pause on Learning Cards: Writing Effective Issues. What should a learner take away from it?\n\n[ALEX]\nLearning Cards: Writing Effective Issues has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nHere is the part to remember. Use fenced code blocks (triple backticks) when pasting error messages or screen reader output; your screen reader announces \"code block\" so listeners know the text is literal, not description. When writing \"Steps to Reproduce,\" type each step as a numbered Markdown list item (1., 2., etc.) so screen readers announce \"list with N items\". Type in the comment body to trigger issue autocomplete; press Down Arrow to navigate matching issues and Enter to insert a cross-reference link. Use the Preview tab (next to Write) to check your Markdown rendering before submitting; headings, bold text, and code blocks are much easier to proofread in rendered form. Screenshots with alt text are valuable evidence; add them with the image button in the formatting toolbar or drag-and-drop into the body field. Keep paragraphs short (3-4 sentences max) so the issue is scannable at high zoom without excessive scrolling.\n\n[JAMIE]\nLet's pause on Try It: File Your First Issue. What should a learner take away from it?\n\n[ALEX]\nAnchor this part on Try It: File Your First Issue. Time: 3 minutes What you need: Browser, signed in to GitHub. This is the part to say slowly: Go to the Learning Room repository and file a real issue. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[ALEX]\nThink of this as 4 checks: Navigate to the Issues tab (press G then I in Focus Mode); Find and activate the \"New issue\" button (K to links, or Tab to it); In the title field, type: \"Introduce myself - [Your Name]\"; and In the description, write 2-3 sentences: who you are, what screen reader you use, and one thing you're hoping to learn today. The point is not speed; the point is never losing your place.\n\n[JAMIE]\nBefore we leave Try It: File Your First Issue, what is the practical point?\n\n[ALEX]\nThe path is straightforward once it is named. Step one is press Ctrl+Enter to submit (or Tab to the Submit button and press Enter). Each step should leave a trace you can name.\n\n[JAMIE]\nLet's pause on Learning Cards: Filing Your First Issue. What should a learner take away from it?\n\n[ALEX]\nThe reason this matters is simple: day 2 Amplifier - Accessibility Agents: @issue-tracker File, read, comment on, and triage real issues manually before using any agent. The listener should be able to check this: If you have not done the triage work yourself - reading descriptions, assigning labels, identifying duplicates - you cannot evaluate whether an agent's priority scoring is correct.\n\n[ALEX]\nHere is the part to remember. After pressing Ctrl+Enter to submit, listen for the page reload; GitHub navigates to your new issue page where the title is the first heading -- press 1 to confirm it matches what you typed. Navigate the issue list with 3 (heading level 3) to jump between issue titles; this is faster than arrowing through every element on the page. If the template picker appears, use Tab and Enter to select \"Open a blank issue\"; template names are announced as link text. The \"New issue\" button is prominent and green on the Issues list page; at high zoom it remains visible near the top of the page and does not collapse into a menu.\n\n[PAUSE]\n\n[JAMIE]\nWhat should people carry with them after this?\n\n[ALEX]\nCarry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.\n\n[JAMIE]\nThat is a better way to say it than just follow the steps.\n\n[ALEX]\nRight. Steps matter, but understanding wins. That is episode 5. Next in the series is episode 6, where we keep building the same contributor muscles.\n",

Listen before reading to preview the concepts, or after to reinforce what you learned.\r\n\r\n> **Related appendices:** [Appendix N: Advanced Search](appendix-n-advanced-search.md) | [Appendix V: GitHub Mobile](appendix-v-github-mobile.md) | [Appendix B: Screen Reader Cheat Sheet](appendix-b-screen-reader-cheatsheet.md)\r\n> **Authoritative sources:** [GitHub Docs: About issues](https://docs.github.com/en/issues/tracking-your-work-with-issues/about-issues) | [GitHub Accessibility Guide: Issues](https://accessibility.github.com/documentation/guide/issues/)\r\n\r\n\r\n## Filing, Managing, and Participating in GitHub Issues\r\n\r\n> Issues are where open source collaboration begins. This guide covers everything from finding the right issue to file a perfect bug report - all with your keyboard and screen reader.\r\n>\r\n> **Official GitHub Accessibility Guide:** GitHub publishes an NVDA-focused guide for working with issues using a screen reader at [Using GitHub Issues with a Screen Reader](https://accessibility.github.com/documentation/guide/issues/). This chapter covers the same material with additional perspectives (VoiceOver, low vision, CLI) and workshop-specific challenges. Use the official guide as a companion reference.\r\n>\r\n> **Screen reader note - New Issues Experience:** This guide uses GitHub's improved Issues experience, which provides better ARIA landmark structure and live-region announcements for screen readers. This feature may already be active for your account - it has been broadly rolled out and may no longer appear as a Feature Preview toggle at all.\r\n>\r\n> **To verify:** Activate the **User Menu** button (top-right of any GitHub page) → activate **\"Feature preview\"** → scan the list for **\"New Issues Experience\"**:\r\n>\r\n> - If listed and the toggle announces **\"Pressed\"** (or **\"Disable\"**) - already enabled, no action needed\r\n> - If listed but **not Pressed** (or **\"Enable\"**) - activate the toggle to enable it\r\n> - If not listed at all - the feature has graduated to the standard interface; it is active automatically\r\n>\r\n> Full step-by-step instructions with per-screen-reader commands are in [Pre-Workshop Setup, Step 4](00-pre-workshop-setup.md#step-4---check-github-feature-preview-settings).\r\n>\r\n> **Browse vs Focus Mode (NVDA):** Toggle between modes with `NVDA+Space` (NVDA key = `Insert` or `Caps Lock`). Use **Browse Mode** (the default) for reading lists, headings, and issue content. Switch to **Focus Mode** when typing in text fields and search boxes. Use `NVDA+F7` at any time to open a list of all headings, links, form fields, buttons, and landmarks on the page - this is your orientation tool.\r\n\r\n\r\n## Workshop Recommendation (Chapter 5 / Challenges 2-3)\r\n\r\nChapter 5 is the first **issue-based challenge chapter** with short, confidence-building tasks. It supports Challenge 2 (File Your First Issue) and Challenge 3 (Join the Conversation).\r\n\r\n- **Challenge count:** 2 core challenges plus one optional extension\r\n- **Time per challenge:** under 10 minutes\r\n- **Evidence:** issue comments and issue metadata\r\n- **Pattern:** claim -> act -> confirm\r\n\r\n### Chapter 5 Challenge Set\r\n\r\n1. **Create your first issue** - file a new issue with a clear title and description.\r\n2. **Comment and @mention** - leave a comment on a classmate's issue and tag them with an @mention.\r\n3. **Optional extension: Add a sub-issue** - break a larger issue into smaller, trackable pieces if your repository has sub-issues enabled.\r\n\r\n> **Branch guidance for Chapter 5:** Chapter 5 focuses on issue skills. You do NOT need to create a branch or edit any files for these challenges. All your work happens in GitHub issue threads. File editing and branches start in Chapter 6.\r\n>\r\n> **How completion works:** When you finish the issue challenges, post evidence in your assigned challenge issues with links to the issue you created and the comment you posted. The facilitator reviews your issue activity directly. No pull request is required for Chapter 5.\r\n\r\n### Challenge 2 Step-by-Step: Create Your First Issue\r\n\r\n**Goal:** File a new issue in your Learning Room repository with a specific title and a meaningful description.\r\n\r\n> **Agentic strategy:** Issues are the prompts that wake up AI. A clear issue for a human is also a prompt for an agent. For this challenge, log an issue describing an accessibility problem or chore you wish an AI agent could fix for you.\r\n\r\n**Where you are working:** the Issues tab of your Learning Room repository on GitHub.com.\r\n\r\n1. Open your Learning Room repository in your browser.\r\n2. Navigate to the **Issues** tab (press `G` then `I` to jump there with keyboard shortcuts, or find the \"Issues\" link in the repository navigation).\r\n3. Activate the **New issue** button.\r\n4. If a template picker appears, select **Open a blank issue** (or choose a template if one fits).\r\n5. In the **Title** field, type a clear, specific title (at least 12 characters). Examples:\r\n   - \"Agent Request: Add missing contributor background paragraph in welcome.md\"\r\n   - \"Keyboard shortcuts table has incorrect NVDA modifier key\"\r\n   - \"Setup guide link to accessibility settings is broken\"\r\n6. In the **Body** field, write a meaningful description (at least 80 characters). Include:\r\n   - What the problem is or what content is missing.\r\n   - Where in the repository the problem exists (file name and section).\r\n   - What you think the fix should be.\r\n7. Activate **Submit new issue**.\r\n8. Copy the issue URL or note the issue number (for example, `#150`). You will reference this later.\r\n\r\n**You are done when:** Your new issue appears in the Issues list with your username as the author, a clear title, and a detailed description.\r\n\r\n### Challenge 3 Step-by-Step: Comment and @Mention\r\n\r\n**Goal:** Leave a comment on another student's issue and use an @mention to notify them.\r\n\r\n**Where you are working:** the Issues tab of your Learning Room repository on GitHub.com.\r\n\r\n1. Open the **Issues** tab in your Learning Room repository.\r\n2. Find an issue created by a classmate (look for recent open issues, or use a facilitator-provided peer-simulation issue).\r\n3. Open the issue by activating its title link.\r\n4. Read the issue description to understand what they reported.\r\n5. Scroll to the comment box at the bottom of the issue.\r\n6. Write a helpful comment that **@mentions the issue author by username**. Examples:\r\n   - \"@classmate I can confirm this - the link in setup-guide.md goes to a 404 page.\"\r\n   - \"@classmate Good catch! I think the correct shortcut is Insert+F7, not Insert+F5.\"\r\n   - \"@classmate I'd suggest adding the paragraph right after the 'Who Can Contribute' heading.\"\r\n7. Activate the **Comment** button (or press `Ctrl+Enter`).\r\n\r\n**Why @mentions matter:** When you type `@username`, GitHub sends that person a notification. This is how real open source teams communicate - you signal who needs to see your message. It also bridges into Chapter 10 (Notifications) where you will configure how you receive these alerts.\r\n\r\n**You are done when:** Your comment appears in the thread and includes an @mention (the username renders as a clickable link).\r\n\r\n### Optional Extension Step-by-Step: Add a Sub-Issue\r\n\r\n**Goal:** Break a larger issue into smaller, trackable pieces using GitHub's sub-issue feature.\r\n\r\n**Where you are working:** the issue you created in Challenge 2 (or any open issue you have permission to edit).\r\n\r\n> **What are sub-issues?** Sub-issues let you decompose a big task into smaller steps, each tracked independently. The parent issue shows a progress bar as sub-issues are completed. This is how teams organize real work - a single \"Fix accessibility in welcome.md\" issue might have sub-issues for each specific fix.\r\n\r\n1. Open the issue you created in Challenge 2.\r\n2. Look for the **Sub-issues** section in the issue sidebar (right side on desktop). If you do not see it, look for an **Add sub-issue** button or the **Create sub-issue** option below the issue description.\r\n3. Activate **Add sub-issue** and choose **Create new sub-issue**.\r\n4. Give the sub-issue a clear title that describes one specific piece of the parent issue. For example, if the parent is \"Fix accessibility in welcome.md\":\r\n   - Sub-issue: \"Add alt text to welcome banner image\"\r\n   - Sub-issue: \"Fix heading hierarchy in Getting Started section\"\r\n5. Add a short description and activate **Create**.\r\n6. The sub-issue now appears nested under the parent issue with a progress indicator.\r\n\r\n**You are done when:** Your parent issue shows at least one sub-issue in the Sub-issues section.\r\n\r\n### Completing Chapter 5: Submit Your Evidence\r\n\r\nWhen you have finished the Chapter 5 issue challenges, go to your **assigned Challenge 2 or Challenge 3 issue** and post a comment with your evidence:\r\n\r\n```text\r\nChapter 5 completed:\r\n- Challenge 2: Created issue #[number]\r\n- Challenge 3: Commented with @mention on issue #[number]\r\n- Optional: Added sub-issue to issue #[number]\r\n```\r\n\r\nReplace `[number]` with the actual issue numbers. Then close your assigned challenge issues. The facilitator will review your issue activity.\r\n\r\n### Expected Outcomes\r\n\r\n- Student can create an issue with a clear title and description.\r\n- Student can communicate in issue threads using @mentions.\r\n- Student can organize work by breaking issues into sub-issues.\r\n\r\n### If You Get Stuck\r\n\r\n1. Can't find a classmate's issue? Filter the Issues tab by `is:open` and look for recent ones.\r\n2. @mention not working? Make sure you type `@` immediately followed by the username with no space.\r\n3. Sub-issue option not visible? Ask a facilitator - the feature may need to be enabled for the repository.\r\n4. Still stuck? Ask a facilitator for a direct issue link.\r\n5. Finished but not sure you did it right? Compare your work against the [Challenge 2 reference solution](solutions/solution-02-first-issue.md) or the [Challenge 3 reference solution](solutions/solution-03-conversation.md).\r\n\r\n### Learning Moment\r\n\r\nIssues are collaborative spaces, not just task lists. An @mention tells someone \"I need your attention here.\" Sub-issues turn vague tasks into clear checklists. Both skills are used daily in real open source projects.\r\n\r\n### Learning Pattern Used in This Chapter\r\n\r\n1. Start with a small, safe action (create an issue).\r\n2. Practice communication in public issue threads (@mention a peer).\r\n3. Organize work into smaller pieces (sub-issues).\r\n4. Leave clear evidence in the issue timeline.\r\n5. Build momentum for file editing and PR work in Chapter 6.\r\n\r\n\r\n### About Learning Cards in This Chapter\r\n\r\nThis chapter provides learning cards: expandable blocks that offer perspective-specific guidance for different ways of working. Not every card appears at every step. Open the ones that match how you work.\r\n\r\nThe following table describes the five learning card types used in this chapter.\r\n\r\n| Card | Who it helps | What it covers |\r\n| --- | --- | --- |\r\n| Visual / mouse | Sighted users navigating with a mouse or trackpad | Click targets, visual cues, layout orientation |\r\n| Low vision | Users with magnification, zoom, or high-contrast themes | Zoom-friendly navigation, finding controls at high magnification, high contrast visibility |\r\n| NVDA / JAWS (Windows) | Screen reader users on Windows | Keystroke sequences, Focus and Browse mode, landmark navigation |\r\n| VoiceOver (macOS) | Screen reader users on macOS | VO key sequences, rotor usage, interaction model |\r\n| CLI (gh) | Terminal users on any platform | GitHub CLI commands for issue management |\r\n\r\n\r\n## Local Git Alternative: Working from Your Clone\r\n\r\n<details>\r\n<summary>If you cloned the learning-room in Block 0 and prefer working locally</summary>\r\n\r\nDuring Block 0 you cloned the Learning Room repository to your computer. If you are comfortable in a terminal, you can use the GitHub CLI (`gh`) from inside that clone for every issue operation in this chapter. This is the same workflow covered in depth in [Chapter 11: Git and Source Control](14-git-in-practice.md).\r\n\r\n**Verify your clone is ready:**\r\n\r\n```bash\r\ncd ~/Documents/learning-room   # or wherever you cloned it\r\ngit status                      # should show \"On branch main\"\r\n```\r\n\r\n**Common issue commands from your local terminal:**\r\n\r\n```bash\r\n# List your assigned challenge issues\r\ngh issue list --assignee @me --label challenge\r\n\r\n# View a specific issue in the terminal\r\ngh issue view 42\r\n\r\n# Leave a comment on an issue\r\ngh issue comment 42 --body \"I'd like to try this!\"\r\n\r\n# Create a new issue interactively\r\ngh issue create\r\n```\r\n\r\nAll of these produce the same result as the web interface. The chapter instructions work identically either way - choose whichever is more comfortable for you.\r\n\r\n</details>\r\n\r\n\r\n## What Is a GitHub Issue?\r\n\r\nAn issue is a discussion thread attached to a repository. Issues are used for:\r\n\r\n- **Bug reports** - \"This feature doesn't work when using a screen reader\"\r\n- **Feature requests** - \"It would help if the submit button had an accessible label\"\r\n- **Questions** - \"How do I configure X for Y use case?\"\r\n- **Tasks** - \"Update the README with screen reader instructions\"\r\n- **Accessibility reports** - \"The infinite scroll carousel is not keyboard accessible\"\r\n\r\nEvery issue has a **number** (`#42`), a **state** (Open or Closed), a **title**, a **description**, and a **comment thread**. Issues are public by default on public repositories.\r\n\r\n> **Learning Room connection:** In your Learning Room repo, every challenge from `docs/CHALLENGES.md` becomes an issue. For example, Challenge 1 (\"Fix Broken Link\") is filed as an issue pointing to `docs/welcome.md`, describing the broken link and linking to the challenge success criteria. When you open a PR to fix it, you reference the issue with `Closes #XX` to automatically close it on merge.\r\n\r\n\r\n## Navigating to the Issues List\r\n\r\n### From a repository page\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nClick the **Issues** tab in the repository navigation bar below the repository name. The tab shows the open issue count (e.g., “Issues · 14”).\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (NVDA / JAWS - Windows)</summary>\r\n\r\n1. Press `D` to navigate to the \"Repository navigation\" landmark\r\n2. Press `K` or `Tab` to move through the tab links\r\n3. Find \"Issues\" - it will be announced with the count: \"Issues, 14 open\"\r\n4. Press `Enter` to open the Issues tab\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Screen reader users (VoiceOver - macOS)</summary>\r\n\r\n1. `VO+U` → Landmarks → navigate to \"Repository navigation\"\r\n2. `VO+Right` or Quick Nav `K` to move through tab links\r\n3. Find \"Issues\" - VoiceOver announces the count: \"Issues 14\"\r\n4. `VO+Space` to activate the Issues tab\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>GitHub CLI (gh) alternative</summary>\r\n\r\nList open issues directly from your terminal:\r\n\r\n```bash\r\ngh issue list\r\n```\r\n\r\nFilter by label, assignee, or state:\r\n\r\n```bash\r\ngh issue list --label \"good first issue\"\r\ngh issue list --assignee @me\r\ngh issue list --state closed\r\n```\r\n\r\n**Setup:** Install the GitHub CLI from [cli.github.com](https://cli.github.com) and authenticate with `gh auth login`. See [Appendix D](appendix-d-git-authentication.md) for details.\r\n\r\n</details>\r\n\r\n### Direct URL\r\n\r\nNavigate directly: `https://github.com/[owner]/[repo]/issues`\r\n\r\n### Learning Cards: Navigating to the Issues List\r\n\r\n**Screen reader users:**\r\n- Press `D` to jump to the \"Repository navigation\" landmark, then `K` or `Tab` to find the Issues link -- this is faster than arrowing through the entire page\r\n- The Issues tab announces its open count (\"Issues, 14 open\"), giving you an instant sense of project activity without loading the list\r\n- Use `gh issue list` in the terminal to bypass browser navigation entirely; pipe through `--label` or `--assignee @me` to pre-filter results\r\n\r\n**Low-vision users:**\r\n- The Issues tab count badge may be small at default zoom; at 200%+ the tab text reflows but the count remains visible next to the word \"Issues\"\r\n- Bookmark the direct URL pattern (`github.com/owner/repo/issues`) to skip repository page navigation altogether\r\n- In high-contrast mode, the active tab is indicated with an underline using system highlight color, not just a subtle background change\r\n\r\n**Sighted users:**\r\n- The Issues tab sits in the repository navigation bar directly below the repo name; the open count badge gives a quick pulse check on project health\r\n- Memorize the `G I` keyboard shortcut (press G, release, press I) to jump to Issues from anywhere in the repository without scrolling\r\n- The direct URL pattern works for any repository: swap `[owner]/[repo]` with real values and bookmark your most visited projects\r\n\r\n\r\n## The Issues List Page\r\n\r\n### Page structure\r\n\r\n```\r\n[Search / filter bar]          -- controls at the top\r\n[State tabs: Open / Closed]    -- filter by status\r\n[Issues list]                  -- each issue is one list item or heading\r\n[Pagination]                   -- at the bottom\r\n```\r\n\r\n> **Quick orientation tip:** Press `NVDA+F7` (or `VO+U` on macOS) to open a list of all headings, links, form fields, and buttons on the page. This is often faster than tabbing through many elements and helps you understand the full page structure before diving in. Use `Ctrl+/` (Windows) or `Cmd+/` (Mac) to jump directly to the search field from anywhere on the page.\r\n\r\n### How to read the issue list\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nThe issues list shows each issue as a row with its title, labels, number, assignee avatars, and comment count. Closed issues show a purple merged/closed badge. Click any issue title to open it. Use the **Open** and **Closed** toggle links above the list to switch between states.\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users (zoom, high contrast)</summary>\r\n\r\nEach issue row shows the title, labels (colored badges), number, and comment count.

Numbered list |\r\n\r\n### GitHub shortcuts for the Issues pages\r\n\r\nThese are the GitHub built-in shortcuts for working with issues. Enable Focus Mode first (NVDA: `NVDA+Space`, JAWS: `Insert+Z`) before using single-key shortcuts.\r\n\r\n#### On the Issues list page\r\n\r\n| Shortcut | Action |\r\n| ---  | ---  |\r\n| `?` | Show all shortcuts for this page |\r\n| `G I` | Jump to the Issues tab from anywhere in the repo |\r\n| `C` | Create a new issue |\r\n\r\n**Shortcut note:** For `G I`, press `G`, release it, then press `I` (two sequential key presses, not simultaneous).\r\n| `Ctrl+/` (Win) or `Cmd+/` (Mac) | Focus the issues search and filter bar |\r\n| `U` | Filter by author |\r\n| `L` | Filter by or edit labels |\r\n| `M` | Filter by or edit milestones |\r\n| `A` | Filter by or edit assignee |\r\n| `O` or `Enter` | Open the selected issue |\r\n\r\n#### On an open issue\r\n\r\n| Shortcut | Action |\r\n| ---  | ---  |\r\n| `M` | Set a milestone |\r\n| `L` | Apply a label |\r\n| `A` | Set an assignee |\r\n| `X` | Link a related issue from the same repository |\r\n| `R` | Quote selected text in your reply (select text first) |\r\n| `Ctrl+Shift+P` (Win) or `Cmd+Shift+P` (Mac) | Toggle Write and Preview tabs |\r\n| `Ctrl+Enter` | Submit comment from inside the text area |\r\n\r\n> **`R` to quote is a power move:** Select any text in a comment while in Browse Mode (`Shift+Arrow` to select), then press `R`. GitHub puts the quoted text in the comment box as a Markdown blockquote. Much faster than typing `>` manually.\r\n\r\nFor the full shortcut system, see [Screen Reader Cheat Sheet - GitHub Shortcuts section](appendix-b-screen-reader-cheatsheet.md#github-built-in-keyboard-shortcuts).\r\n\r\n1.

Navigate to the repository's **Issues** tab (or press `G` then `I`).\r\n2. Click **New issue**, choose a template or blank issue.\r\n3. Fill in the title and description, then click **Submit new issue**.\r\n\r\n**github.dev (web editor):**\r\nNot available -- issues are managed through the repository's Issues tab, not the code editor.\r\n\r\n**VS Code Desktop (GitHub Pull Requests extension):**\r\n1. Open the **GitHub** panel in the sidebar.\r\n2. Under **Issues**, click the **+** icon to create a new issue.\r\n3. Fill in the title and body, then click **Create**.\r\n\r\n**GitHub Desktop:**\r\nNot directly supported. Click **Repository > View on GitHub** to open the browser, then file the issue there.\r\n\r\n**Git CLI / GitHub CLI:**\r\n```bash\r\ngh issue create --title \"Your title\" --body \"Description here\"\r\n# Or interactively:\r\ngh issue create\r\n```\r\n\r\n\r\n## Cross-Referencing Issues\r\n\r\nLinking issues and PRs to each other creates a trail of context that helps everyone understand the project's history.\r\n\r\n### Closing keywords in PR descriptions or issue comments\r\n\r\nWhen you type these phrases in a PR description or comment (followed by an issue number), GitHub creates a connection:\r\n\r\n| Keyword | Effect on merge |\r\n| ---------  | ----------------  |\r\n| `Closes #42` | Closes issue #42 when the PR merges |\r\n| `Fixes #42` | Same - typically for bugs |\r\n| `Resolves #42` | Same - general use |\r\n| `refs #42` | Creates a reference without auto-closing |\r\n| `cc @username` | Notifies the person |\r\n\r\n### Mentioning another issue in a comment\r\n\r\nSimply type `#` followed by a number anywhere in a comment body. GitHub autocompletes with a dropdown of matching issues and PRs:\r\n\r\n```text\r\nStep 1: Type # in the comment box (Focus Mode)\r\nStep 2: A dropdown appears with issues and PRs\r\nStep 3: ↑/↓ to navigate, or type more numbers to filter\r\nStep 4: Enter to insert the reference\r\n```\r\n\r\n### Cross-repo references\r\n\r\n`owner/repo#42` - references issue #42 in a different repository.\r\n\r\n### Learning Cards: Cross-Referencing Issues\r\n\r\n**Screen reader users:**\r\n- Type `#` in any comment body to trigger GitHub's autocomplete dropdown; press `Down Arrow` to browse matching issues and `Enter` to insert the reference link\r\n- Use `Closes #42` (not just `#42`) in PR descriptions so GitHub automatically closes the issue on merge; your screen reader will confirm the link is created in the PR timeline\r\n- Cross-references appear as timeline events on the linked issue; navigate with `H` to find \"mentioned this issue\" entries to trace the conversation history\r\n\r\n**Low-vision users:**\r\n- Cross-reference links (`#42`) render as colored, clickable links in both issue bodies and PR descriptions; at high zoom they remain inline with surrounding text\r\n- The autocomplete dropdown triggered by `#` may overlap content at high magnification; type additional digits to narrow results and reduce dropdown size\r\n- Back-links appear automatically on the referenced issue's timeline, so you can verify the connection was created by visiting either side\r\n\r\n**Sighted users:**\r\n- Use `Closes #42`, `Fixes #42`, or `Resolves #42` in PR descriptions for auto-closing on merge; `refs #42` creates a reference without auto-close, useful for \"related but not solved\" links\r\n- GitHub's autocomplete (`#` then type) searches both issue titles and numbers, so you can find issues by keyword without memorizing numbers\r\n- Cross-repo references use the format `owner/repo#42` -- useful when your PR in one repository fixes a bug tracked in another\r\n\r\n\r\n## Sub-Issues - Parent and Child Relationships\r\n\r\n**Sub-issues** (released 2025) let you nest issues inside a parent issue to break large work into tracked pieces. A \"parent\" issue contains a list of child issues; each child is a full issue with its own discussion, labels, and assignees.\r\n\r\n### When to Use Sub-Issues\r\n\r\n| Use case | Example |\r\n| ----------  | ---------  |\r\n| Large feature broken down | Parent: \"Redesign navigation\"; Children: \"Keyboard nav,\" \"Screen reader nav,\" \"Mobile nav\" |\r\n| Epic tracking | Parent: \"WCAG 2.1 AA compliance\"; Children: one issue per failing criterion |\r\n| Release milestone | Parent: \"v2.0 release\"; Children: every required PR/fix |\r\n\r\n### Creating a Sub-Issue\r\n\r\nFrom any open issue:\r\n\r\n```text\r\n1. Open the parent issue page\r\n2. Scroll to (or H-navigate to) the \"Sub-issues\" section in the issue body/sidebar\r\n3. Tab to \"Add sub-issue\" button → Enter\r\n4. Type the issue number or title to search\r\n5. Select the issue from the dropdown → Enter to link\r\n   Or: select \"Create new issue\" to create and link in one step\r\n```\r\n\r\n**Screen reader note:** The sub-issues section is announced as a region. After linking, the child issue appears as a list item with a checkbox showing its open/closed state. Tab through to read each child's title and status.\r\n\r\n### Reading Sub-Issues on a Parent Issue\r\n\r\n```text\r\nH → \"Sub-issues\" heading\r\n↓ → list of linked child issues\r\nEach item: [checkbox state] [issue title] [#number] [open/closed badge]\r\nTab → \"Add sub-issue\" button (if you have write access)\r\n```\r\n\r\n**Progress indicator:** The parent issue shows a completion bar (e.g., \"3 of 7 completed\") based on how many child issues are closed. Screen readers announce this as a progress region.\r\n\r\n### Viewing a Child Issue's Parent\r\n\r\nEvery child issue shows a \"Parent issue\" link near the top of the page (above the description). Navigate with `H` or links (`K`) to find it.\r\n\r\n### Sub-Issues vs. Task Lists\r\n\r\n| Feature | Task list checkboxes | Sub-issues |\r\n| ---------  | ---------------------  | ------------  |\r\n| Location | Issue description (Markdown) | Sidebar/section (structured data) |\r\n| Each item is | Text line + checkbox | A full GitHub issue |\r\n| Tracked in Projects | No (checkbox only) | Yes (each child tracks independently) |\r\n| Cross-repo | No | Yes |\r\n| Best for | Quick checklists in one issue | Multi-issue work tracking |\r\n\r\n> **Workshop tip:** If you are working on a feature that requires multiple PRs or involves several team members, ask the maintainer to create a parent issue. You can then claim individual child issues without one person owning the whole feature.\r\n\r\n### Learning Cards: Sub-Issues\r\n\r\n**Screen reader users:**\r\n- The sub-issues section is announced as a region; press `H` to navigate to the \"Sub-issues\" heading, then arrow down through the list where each child announces its checkbox state, title, and open/closed badge\r\n- The parent issue shows a progress indicator (\"3 of 7 completed\") announced as a progress region; listen for this after the sub-issues heading to gauge overall status\r\n- Every child issue includes a \"Parent issue\" link near the top of its page; navigate with `K` (links) to find it and jump back to the parent quickly\r\n\r\n**Low-vision users:**\r\n- The completion progress bar on the parent issue uses color to show progress; in high-contrast mode, completed vs. remaining segments use distinct system colors\r\n- At high zoom, the \"Add sub-issue\" button may wrap below the sub-issues list; Tab past the last child item to reach it\r\n- Each child issue's open/closed badge uses both color and text (\"Open\" or \"Closed\"), so status is readable without relying on color alone\r\n\r\n**Sighted users:**\r\n- Sub-issues appear as a checklist with a progress bar on the parent issue; each child links directly to its own issue page with full discussion and labels\r\n- Use sub-issues instead of Markdown task-list checkboxes when each item needs its own assignee, labels, or cross-repo tracking -- sub-issues are structured data, not just text\r\n- Creating a sub-issue from the parent's \"Add sub-issue\" button auto-links the new issue; you can also link existing issues by searching their number or title\r\n\r\n\r\n## Managing Issues (for Maintainers and Triagers)\r\n\r\n### Closing an issue\r\n\r\n<details>\r\n<summary>Visual / mouse users</summary>\r\n\r\nScroll to the bottom of the issue page.

Navigate to \"Labels\" heading\r\n2. Activate the gear button\r\n3. Select/deselect labels from the dropdown\r\n4. Press Escape to save\r\n\r\n### Transferring or deleting an issue\r\n\r\nAvailable from the \"...\" (ellipsis) button at the top of the issue - navigate buttons with `B` to find it.\r\n\r\n### Learning Cards: Managing Issues\r\n\r\n**Screen reader users:**\r\n- Close an issue instantly with `Ctrl+Shift+Enter` from the comment text area (Focus Mode) -- no need to Tab to the Close button\r\n- The sidebar sections (Assignees, Labels, Milestone) each have their own heading; press `H` or `3` to jump between them, then activate the gear icon to open each dropdown\r\n- Use `gh issue edit 42 --add-label \"accessibility\" --add-assignee @me` to batch-update labels and assignments from the terminal without navigating sidebar controls\r\n\r\n**Low-vision users:**\r\n- Sidebar controls (Assignees, Labels, Milestone) are narrow at default width; at high zoom they stack vertically and each dropdown opens a searchable overlay that is easier to read\r\n- The Close issue button turns green and its label changes to \"Reopen issue\" once closed; in high-contrast mode, both states use distinct system colors\r\n- Type in the search field inside each sidebar dropdown (Labels, Assignees) to filter long lists rather than scrolling through all options at high magnification\r\n\r\n**Sighted users:**\r\n- The issue sidebar on the right contains Assignees, Labels, Projects, and Milestone in collapsible sections; click the gear icon next to each to open the edit dropdown\r\n- Use the dropdown arrow on the Close button to choose \"Close as completed\" vs. \"Close as not planned\" -- this distinction helps with project tracking and search filtering\r\n- The \"...\" menu at the top of any issue provides Transfer, Pin, Lock, and Delete options for repository maintainers\r\n\r\n\r\n## The \"good first issue\" Label - Your Entry Point\r\n\r\nWhen looking for your first open source contribution:\r\n\r\n1. Navigate to any project's Issues tab\r\n2. Filter by label: type `is:open label:\"good first issue\"` in the search\r\n3. Read through issues until you find one in your area of interest\r\n4. Comment on the issue: \"Hi, I'd like to work on this. Can I be assigned?\"\r\n5. Wait for a maintainer to respond and assign you before starting work\r\n\r\n**Remember:** It's respectful to ask before starting. Maintainers juggle many discussions and need to know who is working on what to avoid duplicated effort.\r\n\r\n### Learning Cards: The \"good first issue\" Label\r\n\r\n**Screen reader users:**\r\n- Use the filter query `is:open label:\"good first issue\"` in the search bar to jump directly to beginner-friendly issues; `gh issue list --label \"good first issue\"` does the same in the terminal\r\n- Before claiming an issue, read existing comments to check whether someone else has already been assigned; listen for \"assigned to\" in the sidebar metadata\r\n- When you comment to claim an issue, include a sentence about your approach so the maintainer can give early feedback before you start coding\r\n\r\n**Low-vision users:**\r\n- The \"good first issue\" label renders with a distinct background color (typically light purple or teal); in high-contrast mode it uses system highlight colors with readable text\r\n- Filter results may include issues with multiple labels stacked together; at high zoom, labels wrap to a second line but remain readable\r\n- Bookmark the filtered URL (`/issues?q=is:open+label:\"good first issue\"`) in your browser for one-click access to beginner issues across your favorite repositories\r\n\r\n**Sighted users:**\r\n- The \"good first issue\" label is a GitHub convention recognized across the ecosystem; many projects also use \"help wanted\" for intermediate tasks\r\n- Always comment before starting work -- even if unassigned -- to avoid duplicating effort with another contributor who may already be working quietly\r\n- Read the issue's linked PR history (if any) to see whether previous attempts were made and why they were closed; this saves you from repeating known dead ends\r\n\r\n\r\n## Accessibility-Specific Issue Writing Tips\r\n\r\nWhen filing accessibility bugs, these details help maintainers reproduce and fix the problem:\r\n\r\n1. **Screen reader and version** - \"NVDA 2025.3.3\" not just \"screen reader\"\r\n2. **OS and version** - \"Windows 11 22H2\"\r\n3. **Browser and version** - \"Chrome 124.0.6367.82\"\r\n4. **GitHub interface** - \"Modern experience (default since Jan 2026)\" or \"Classic experience (opted out)\"\r\n5. **What was announced** - quote the exact text your screen reader spoke\r\n6. **What should have been announced** - describe the expected behavior\r\n7. **ARIA issue if known** - e.g., \"The button has no accessible name\"\r\n8. **Steps to reproduce** - numbered, step-by-step\r\n9. **Frequency** - \"This happens every time\" vs \"intermittent\"\r\n\r\n### Example of a well-filed accessibility issue\r\n\r\n```text\r\nTitle: Issues list does not announce label filtering results to screen readers\r\n\r\n## What happened\r\nWhen I apply a label filter on the Issues list using the Labels dropdown,\r\nthe filtered list updates visually but NVDA does not announce that the\r\nresults changed or how many items are now shown.\r\n\r\n## What I expected\r\nAfter filtering, the screen reader should announce something like\r\n\"14 issues open, filtered by label: accessibility\" or a live region\r\nupdate indicating the results changed.\r\n\r\n## How to reproduce\r\n1. Navigate to any repo's Issues tab\r\n2. Press B to navigate to the \"Label\" filter button\r\n3. Press Enter to open the dropdown\r\n4. Select the \"accessibility\" label\r\n5. Press Escape to close\r\n6. Notice: no announcement that filtering has been applied\r\n\r\n## Environment\r\n- Screen reader: NVDA 2025.3.3 (with NVDA+Chrome)\r\n- Browser: Chrome 124.0.6367.82\r\n- OS: Windows 11 22H2\r\n- GitHub interface: Modern experience (default since Jan 2026)\r\n\r\n## Additional context\r\nJAWS 2026 also does not announce. VoiceOver on macOS Sonoma with\r\nSafari 17 does announce \"List updated\" when filtering is applied,\r\nso the macOS behavior appears correct.\r\n```\r\n\r\n### Learning Cards: Accessibility-Specific Issue Writing\r\n\r\n**Screen reader users:**\r\n- Always quote the exact text your screen reader announced in the issue body; wrap it in a fenced code block so readers know it is literal output, not your description\r\n- Include your screen reader name and version (e.g., \"NVDA 2025.3.3\") plus browser and OS; this lets maintainers reproduce with the same toolchain\r\n- Test with a second screen reader or browser if possible and note the results -- \"Also fails in JAWS 2026 with Chrome; works in VoiceOver with Safari\" dramatically narrows the debugging scope\r\n\r\n**Low-vision users:**\r\n- When filing zoom or contrast bugs, state your exact zoom level and whether you use Windows High Contrast, macOS Increase Contrast, or a browser extension\r\n- Screenshots are powerful evidence; annotate them (circle the problem area, add a text callout) and always include alt text describing what the screenshot shows\r\n- Note whether the issue occurs only at certain zoom levels or viewport widths; a bug at 400% that disappears at 200% points to a CSS breakpoint problem\r\n\r\n**Sighted users:**\r\n- Even if you do not use assistive technology, you can file accessibility issues by testing with keyboard-only navigation (Tab, Enter, Escape) and noting where focus is lost or trapped\r\n- Include the ARIA role or attribute involved if you can identify it from browser DevTools (e.g., \"The button has `role=presentation` and no accessible name\")\r\n- Link to the relevant WCAG success criterion when possible (e.g., \"Fails WCAG 2.1 SC 1.3.1 Info and Relationships\"); this gives maintainers a clear standard to design against\r\n\r\n\r\n## Writing Effective Issues\r\n\r\n> **See also:** [Appendix N: Advanced Search](appendix-n-advanced-search.md) covers search qualifiers to find existing issues before filing a new one.\r\n\r\nA well-written issue saves everyone time -- the maintainer who reads it, the contributor who fixes it, and the future searcher who finds it six months later. This section gives you reusable templates for the two most common issue types and a set of principles that apply to every issue you file.\r\n\r\n### Bug Report Structure\r\n\r\nA strong bug report answers five questions. Use this template every time you report something broken.\r\n\r\n| Section | What to write |\r\n|---|---|\r\n| **Title** | Follow the formula: \"When I [action], [unexpected result] instead of [expected result]\" |\r\n| **Steps to Reproduce** | Numbered list -- start from the earliest relevant step |\r\n| **Expected Behavior** | What *should* happen according to documentation or common sense |\r\n| **Actual Behavior** | What *does* happen -- include exact error messages or screenshots |\r\n| **Environment** | OS, browser, screen reader, app version -- anything that might matter |\r\n\r\nThe title formula is the most important part. A title like \"When I press Enter on the Submit button, nothing happens instead of creating the issue\" tells the maintainer exactly what is broken before they even open the issue.\r\n\r\n> **Screen reader tip:** When pasting error messages into the Actual Behavior section, wrap them in a fenced code block (triple backticks). Screen readers will announce \"code block\" so the listener knows the text is a literal error, not your description.\r\n\r\n**Steps to Reproduce matter more than you think.** Maintainers cannot fix what they cannot recreate. Number every step, starting from a clean slate -- \"Open the repository\" is better than \"Go to the page.\" Include what you clicked, what keyboard shortcut you pressed, and what happened after each step.\r\n\r\n### Feature Request Structure\r\n\r\nFeature requests work best when they focus on the *problem* before jumping to the solution. Use this four-part structure:\r\n\r\n1. **Problem statement** -- Describe the pain point. What are you trying to do, and why is it hard or impossible right now?\r\n2. **Proposed solution** -- Your best idea for fixing the problem. Be specific enough to discuss, but hold it loosely.\r\n3. **Alternatives considered** -- Other approaches you thought about and why they fell short. This shows you have done your homework.\r\n4. **Who benefits** -- Name the audience. \"Screen reader users navigating large repositories\" is more compelling than \"everyone.\"\r\n\r\nA feature request that starts with \"I want a dark mode toggle\" is weaker than one that starts with \"Low-vision users report eyestrain after 20 minutes because the current theme has insufficient contrast.\" The second version gives maintainers something to design around.\r\n\r\n### General Issue Writing Principles\r\n\r\nThese rules apply to every issue -- bugs, features, questions, and everything in between.\r\n\r\n**One issue per problem.** If you discovered two bugs during the same session, file two separate issues. Combining them makes it impossible to close one without the other and clutters the conversation.\r\n\r\n**Write searchable titles.** Future contributors will search before filing. \"Bug with button\" will never surface in a search for \"Submit button unresponsive on Safari.\" Front-load the title with the specific component or action.\r\n\r\n**Include context, not assumptions.** Instead of \"The API is broken,\" write \"The `/repos` endpoint returns a 403 when I pass a valid token.\" Let maintainers draw their own conclusions from the evidence you provide.\r\n\r\n**Link related issues.** If your bug might be connected to issue #42, mention it: \"This might be related to #42.\" GitHub automatically creates a back-link, building a web of context that helps everyone. You will learn more about cross-referencing in [Chapter 6](06-working-with-pull-requests.md).\r\n\r\n| Principle | Bad example | Good example |\r\n|---|---|---|\r\n| One issue per problem | \"The button is broken and also the logo is wrong\" | Two separate issues, each with its own title |\r\n| Searchable title | \"Help needed\" | \"Keyboard focus lost after closing modal dialog\" |\r\n| Context over assumptions | \"Nothing works\" | \"After upgrading to v2.3, the dashboard returns a blank page on Firefox 124\" |\r\n| Link related issues | (no mention) | \"Possibly related to #42 -- same component, different trigger\" |\r\n\r\n### Before and After: A Vague Issue vs. a Clear Issue\r\n\r\n**Vague issue (hard to act on):**\r\n\r\n> **Title:** Bug\r\n>\r\n> It doesn't work. I tried clicking and nothing happened. Please fix.\r\n\r\nThe maintainer has to ask: What doesn't work? Where did you click? What browser? What did you expect? Every follow-up question costs a round-trip of waiting.\r\n\r\n**Clear issue (ready to fix):**\r\n\r\n> **Title:** When I press Enter on the \"New issue\" button, nothing happens instead of opening the issue form\r\n>\r\n> **Steps to Reproduce:**\r\n> 1. Navigate to github.com/org/repo\r\n> 2. Press `G` then `I` to go to the Issues tab\r\n> 3. Tab to the \"New issue\" button\r\n> 4. Press `Enter`\r\n>\r\n> **Expected:** The new issue form opens.\r\n>\r\n> **Actual:** The page does not respond. No error in the console.\r\n>\r\n> **Environment:** Windows 11, Firefox 128, JAWS 2025\r\n\r\nThe maintainer can reproduce this in under a minute. No follow-up questions needed -- the fix can start immediately.\r\n\r\n> **Screen reader tip:** You can use the issue template feature in GitHub to pre-fill these sections automatically. If the repository provides templates, your screen reader will announce each section heading as you Tab through the form. You will set up your own issue templates in [Chapter 17](17-issue-templates.md).\r\n\r\n### Learning Cards: Writing Effective Issues\r\n\r\n<details>\r\n<summary>Screen reader users</summary>\r\n\r\n- Use fenced code blocks (triple backticks) when pasting error messages or screen reader output; your screen reader announces \"code block\" so listeners know the text is literal, not description\r\n- When writing \"Steps to Reproduce,\" type each step as a numbered Markdown list item (`1.`, `2.`, etc.) so screen readers announce \"list with N items\"\r\n- Type `#` in the comment body to trigger issue autocomplete; press `Down Arrow` to navigate matching issues and `Enter` to insert a cross-reference link\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users</summary>\r\n\r\n- Use the Preview tab (next to Write) to check your Markdown rendering before submitting; headings, bold text, and code blocks are much easier to proofread in rendered form\r\n- Screenshots with alt text are valuable evidence; add them with the image button in the formatting toolbar or drag-and-drop into the body field\r\n- Keep paragraphs short (3-4 sentences max) so the issue is scannable at high zoom without excessive scrolling\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Sighted users</summary>\r\n\r\n- A well-structured issue uses H2 headings (##) for major sections: What happened, Expected, How to reproduce, Environment\r\n- GitHub renders Markdown tables in issue bodies; use a table to compare expected vs. actual behavior side by side\r\n- The title appears in issue lists, email notifications, and search results; front-load it with the specific component or action for discoverability\r\n\r\n</details>\r\n\r\n\r\n## Try It: File Your First Issue\r\n\r\n**Time:** 3 minutes | **What you need:** Browser, signed in to GitHub\r\n\r\nGo to the Learning Room repository and file a real issue:\r\n\r\n1. Navigate to the Issues tab (press `G` then `I` in Focus Mode)\r\n2. Find and activate the \"New issue\" button (`K` to links, or `Tab` to it)\r\n3. In the title field, type: **\"Introduce myself - [Your Name]\"**\r\n4. In the description, write 2-3 sentences: who you are, what screen reader you use, and one thing you're hoping to learn today\r\n5. Press `Ctrl+Enter` to submit (or Tab to the Submit button and press `Enter`)\r\n\r\n**You're done.** You just filed your first GitHub issue. Go read someone else's introduction and leave a friendly comment - press `3` to jump between issue titles on the Issues list.\r\n\r\n> **What success feels like:** Your issue is live. Other participants can see it. You just contributed to a real repository - and it took less than three minutes.\r\n\r\n### Learning Cards: Filing Your First Issue\r\n\r\n**Screen reader users:**\r\n- After pressing `Ctrl+Enter` to submit, listen for the page reload; GitHub navigates to your new issue page where the title is the first heading -- press `1` to confirm it matches what you typed\r\n- Navigate the issue list with `3` (heading level 3) to jump between issue titles; this is faster than arrowing through every element on the page\r\n- If the template picker appears, use `Tab` and `Enter` to select \"Open a blank issue\"; template names are announced as link text\r\n\r\n**Low-vision users:**\r\n- The \"New issue\" button is prominent and green on the Issues list page; at high zoom it remains visible near the top of the page and does not collapse into a menu\r\n- The title field is full-width and the body field expands as you type; both are easy to locate and target at any zoom level\r\n- After submitting, your new issue page shows your avatar, title, and description in high-contrast-friendly layout; verify the content rendered correctly before moving on\r\n\r\n**Sighted users:**\r\n- Your issue immediately appears at the top of the Issues list; the green \"Open\" badge confirms it was created successfully\r\n- Read a few other students' introduction issues and leave a comment to practice the commenting workflow from the Leaving a Comment section\r\n- Notice how the issue number (e.g., #150) is auto-assigned and appears in the URL and page title; you will use this number for cross-references later\r\n\r\n\r\n> ### Day 2 Amplifier - Accessibility Agents: `@issue-tracker`\r\n>\r\n> **File, read, comment on, and triage real issues manually before using any agent.** If you have not done the triage work yourself - reading descriptions, assigning labels, identifying duplicates - you cannot evaluate whether an agent's priority scoring is correct. The skill must exist before the amplifier is useful.\r\n>\r\n> Once you have mastered manual issue management:\r\n>\r\n> - **In VS Code** - `@issue-tracker find open issues labeled good-first-issue` searches cross-repository with community sentiment scoring, release-awareness prioritization, and batch-reply capability across every repo you have access to\r\n> - **In your repo** - The issue templates in `accessibility-agents/.github/ISSUE_TEMPLATE/` structure both human filing and automated triage; fork [accessibility-agents](https://github.com/Community-Access/accessibility-agents) and that structure travels into any project you lead\r\n> - **In the cloud** - GitHub Agentic Workflows triage new issues the moment they are opened: applying labels, posting first-response comments, adding to Project boards - the same triage actions you practiced manually today, running at scale\r\n>\r\n> *Today you are the triage engine. On Day 2, you understand the engine well enough to direct it.*\r\n\r\n\r\n> **Challenge Time:** It's time for the real deal. Go to the [Challenge Hub](CHALLENGES.md) and complete **Challenge 2: File Your First Issue** and **Challenge 3: Join the Conversation**. When Aria the bot replies to you, she will tell you when it's time to move to [Chapter 06: Working with Pull Requests](06-working-with-pull-requests.md).\r\n\r\n---\r\n\r\n\r\n*Next: [Chapter 06: Working with Pull Requests](06-working-with-pull-requests.md)*  \r\n*Back: [Chapter 04: The Learning Room](04-the-learning-room.md)*  \r\n*Related appendices: [Appendix N: Advanced Search](appendix-n-advanced-search.md) | [Appendix V: GitHub Mobile](appendix-v-github-mobile.md)*\r\n\r\n\r\n\r\n\r\n"

+  "transcriptText": "[ALEX]\nWelcome to Git Going with GitHub, episode 20: Accessibility Standards Reference. I am Alex. Today we are going to make Accessibility Standards Reference something you can explain, practice, and recover from when the interface surprises you.\n\n[JAMIE]\nAnd I am Jamie. I will be the voice of the learner who is willing to ask, what is this for, where am I, and how do I know I did it right?\n\n[PAUSE]\n\n[ALEX]\nThe big idea today: WCAG 2.2, ARIA roles, and the PR accessibility checklist. We will name the concept, explain why it matters, practice the move, and point out the checks that tell you the work is real.\n\n[JAMIE]\nSo the episode should work even if someone has not read the chapter yet.\n\n[ALEX]\nExactly. The transcript has to stand on its own. It can point toward practice, but it should teach the concept right here in the conversation.\n\n[PAUSE]\n\n[JAMIE]\nOkay, set the room for us. What are we walking into?\n\n[ALEX]\nWCAG, ARIA, and What They Mean for Your Contributions: This appendix gives you a working understanding of the accessibility standards that govern the web, GitHub's interface, and the projects you will contribute to. The next useful detail is concrete: You do not need to memorize these - use this as a lookup when a PR review mentions a specific standard or success criterion.\n\n[ALEX]\nThe next layer is this. Here is the learner-facing version. WCAG (Web Content Accessibility Guidelines) is organized around four principles, often abbreviated POUR. Put another way, every WCAG success criterion belongs to one of these four principles. A good GitHub workflow is like a well-run meeting: everyone knows the topic, the next action, and who has the floor.\n\n[ALEX]\nA solid pull request habit is to separate three questions: what changed, why it changed, and what still needs review. That keeps the conversation useful instead of noisy.\n\n[JAMIE]\nWhat is the one idea that makes the next few steps less mysterious?\n\n[ALEX]\nLearning Cards: WCAG Overview has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThat shows up in the workshop in a few specific ways. WCAG is organized around four principles: Perceivable, Operable, Understandable, Robust (POUR) -- use this mnemonic when reviewing any PR. Most projects target WCAG 2.2 AA -- when a reviewer cites a criterion number like 1.4.3, search the tables in Section 3 of this appendix. The WCAG Quick Reference (Section 10) is a filterable web page -- use your screen reader's find command to jump to any criterion number. The tables in this appendix use pipe-delimited Markdown -- increase your editor font size or use a Markdown preview for cleaner column alignment. WCAG 1.4.3 (contrast) and 1.4.11 (non-text contrast) are the criteria most relevant to your daily experience -- bookmark them. When checking contrast ratios, use the WebAIM Contrast Checker link in Section 10 with your browser zoom set to your preferred level.\n\n[JAMIE]\nThat feels much more doable when you say it as one move.\n\n[ALEX]\nRight. The magic is not speed. The magic is knowing what changed and why it matters.\n\n[PAUSE]\n\n[ALEX]\nNow bring the learner back to the room. Anchor this part on 2. Conformance Levels: A, AA, AAA. Most open source projects, and GitHub itself, target WCAG 2.2 AA compliance. This is the part to say slowly: When you file an accessibility bug or review a PR, AA is the standard to reference.\n\n[JAMIE]\nWhat would you say to someone who is already bracing for this to be too much?\n\n[ALEX]\nThe reason this matters is simple: these are the criteria you will most commonly encounter when contributing to web projects or reviewing GitHub interface changes.\n\n[ALEX]\nThe useful habit is simple: orient, act, verify, then continue. That pause between action and trust is part of the work.\n\n[ALEX]\nThat matters because of the next idea. Do not treat 4. ARIA - Roles, States, and Properties as decoration. WAI-ARIA (Accessible Rich Internet Applications) fills the gap between what HTML natively expresses and what complex interactive widgets require. The workshop is closer to rehearsal than lecture. You hear the move, try the move, and then check what changed.\n\n[PAUSE]\n\n[JAMIE]\nHow would you walk the room through that step by step?\n\n[ALEX]\nImportant rules has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nStart here: Don't use ARIA if native HTML suffices. A is already a button - adding role=\"button\" to a is only needed when HTML semantics cannot be used. Then: All interactive ARIA widgets must be keyboard operable. Adding role=\"button\" means you must also handle Enter and Space keypresses in JavaScript. Next: ARIA only affects the accessibility tree. It does not add visual styling or behavior - it only changes what assistive technologies announce. The sequence works because every action has a confirmation.\n\n[ALEX]\nThis is where the talk moves from concept to action. Put 5. ARIA Landmark Roles into plain language. Landmarks let screen reader users jump directly to major sections of a page. The useful version is: GitHub uses these extensively; screen reader users navigate between them with D (NVDA/JAWS) or the Rotor (VoiceOver).\n\n[JAMIE]\nNow it sounds like a workflow instead of a wall of instructions.\n\n[ALEX]\nThat is where confidence comes from: not from never getting lost, but from knowing how to recover.\n\n[ALEX]\nA solid navigation habit is to prove where you are before activating controls. Headings, landmarks, and the address bar are not trivia; they are your map.\n\n[JAMIE]\nWhere do you want a learner to place their attention here?\n\n[ALEX]\nThe teaching point here is not the label; it is the move. Use aria-live=\"assertive\" only for urgent interruptions (errors). That is the difference between guessing and knowing: Use \"polite\" for non-urgent status updates.\n\n[PAUSE]\n\n[ALEX]\nBefore the learner moves on. This part earns its place because when expanded: set aria-expanded=\"true\" and remove the hidden attribute. That is the difference between following directions and owning the workflow.\n\n[JAMIE]\nGive me the version that sounds like an instructor, not a manual.\n\n[ALEX]\n7. How Standards Apply to GitHub Contributions: When you contribute to an open source project on GitHub, you will encounter accessibility in several contexts.\n\n[ALEX]\nNow slow down for the part people usually miss. Here is the learner-facing version. Reference the specific WCAG criterion. Put another way, bad: \"The button isn't accessible.\" Good: \"The 'Subscribe' button has no visible focus indicator, failing WCAG 2.4.7 Focus Visible (Level AA).\n\n[PAUSE]\n\n[JAMIE]\nIf I am listening before the workshop starts, what should settle in my mind first?\n\n[ALEX]\nThis is the move inside Reviewing a PR for Accessibility: checklist for any PR that touches HTML or UI.\n\n[ALEX]\nThese are the pieces that turn the idea into a usable move. Do new images have alt attributes? Do new interactive elements work with keyboard only? Do new form fields have associated elements? Are any new color-only indicators present? Does new dynamic content use aria-live if it updates without a page load?\n\n[JAMIE]\nThat is the kind of detail that keeps a screen reader user oriented.\n\n[ALEX]\nYes. The named thing - the heading, tab, field, branch, or button - is the handhold.\n\n[ALEX]\nHere is the moment where the page starts to make sense. Anchor this part on Writing Accessible Documentation. Documentation in Markdown is converted to HTML. The durable skill is not memorizing one screen. It is knowing how to find your footing when the screen changes.\n\n[ALEX]\nListen for the small confirmations in this list. Use heading levels in order (don't skip from H1 to H3). Write descriptive link text (not \"click here\"). Add alt text to images. Use actual lists (- or 1.) rather than faking them with symbols.\n\n[JAMIE]\nWhat is the ordered workflow?\n\n[ALEX]\nManual Testing (catches the rest) has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThe path is straightforward once it is named. Step one is keyboard-only navigation - unplug your mouse; can you do everything? Step two is screen reader walkthrough - navigate the feature with NVDA, JAWS, or VoiceOver. Step three is 200% zoom - does content reflow without horizontal scrolling? Step four is high contrast mode - Windows High Contrast or macOS Increase Contrast; are all elements still visible? The sequence works because every action has a confirmation.\n\n[JAMIE]\nGive me the sequence, because order matters here.\n\n[ALEX]\nFirst, disable CSS - does the content still make sense in reading order? Keep it that plain: know where you are, make the move, check the result.\n\n[PAUSE]\n\n[ALEX]\nThe next point gives the learner a handle. Learning Cards: Testing Against Standards has three jobs: name the idea, give the learner a move, and show what counts as evidence.\n\n[ALEX]\nThis is where the lesson becomes something you can check. You are the manual test -- automated tools catch only 30-40% of issues; your screen reader walkthrough catches the rest. Install the axe DevTools browser extension (Section 8 table) and run it on any page; results are announced as a list of violations with WCAG criterion references. When doing a keyboard-only navigation test, press Tab repeatedly and listen -- every interactive element should announce its name and role. The 200% zoom test (item 3) mirrors your daily experience -- if content breaks at 200%, file a bug citing WCAG 1.4.4 Resize Text. Windows High Contrast mode test (item 4) is one click: Settings, Accessibility, Contrast themes -- switch and check that all UI elements remain visible. The WAVE browser extension overlays icons on the page showing errors and warnings -- zoom in to read the small annotation labels.\n\n[JAMIE]\nLet's pause on 10. Official References. What should a learner take away from it?\n\n[ALEX]\nIf the interface shifts, 10. Official References is still useful because next: Appendix N: Advanced Search Back: Appendix L: Agents Reference Teaching chapter: Chapter 08: Open Source Culture.\n\n[PAUSE]\n\n[JAMIE]\nWhat should people carry with them after this?\n\n[ALEX]\nCarry the map. Know what page or tool you are in, know which action you are taking, and know what confirmation should follow. If the confirmation is missing, pause. That pause is not wasted time; it is professional judgment.\n\n[JAMIE]\nThat is a better way to say it than just follow the steps.\n\n[ALEX]\nRight. Steps matter, but understanding wins. That is episode 20. Next in the series is episode 21, where we keep building the same contributor muscles.\n",

WCAG 2.2 - The Four Principles\r\n\r\nWCAG (Web Content Accessibility Guidelines) is organized around four principles, often abbreviated **POUR**:\r\n\r\n| Principle | Meaning | Example Failure |\r\n| -----------  | ---------  | -----------------  |\r\n| **Perceivable** | Information must be presentable to users in ways they can perceive | An image with no alt text - a screen reader user gets nothing |\r\n| **Operable** | UI components and navigation must be operable | A button that only works on hover - keyboard users cannot activate it |\r\n| **Understandable** | Information and operation must be understandable | An error message that says \"Invalid input\" with no explanation of what is wrong |\r\n| **Robust** | Content must be robust enough to be interpreted by assistive technologies | Custom JavaScript widgets with no ARIA roles - screen readers cannot determine what they are |\r\n\r\nEvery WCAG success criterion belongs to one of these four principles.\r\n\r\n### Learning Cards: WCAG Overview\r\n\r\n<details>\r\n<summary>Screen reader users</summary>\r\n\r\n- WCAG is organized around four principles: Perceivable, Operable, Understandable, Robust (POUR) — use this mnemonic when reviewing any PR\r\n- Most projects target WCAG 2.2 AA — when a reviewer cites a criterion number like 1.4.3, search the tables in Section 3 of this appendix\r\n- The WCAG Quick Reference (Section 10) is a filterable web page — use your screen reader's find command to jump to any criterion number\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users</summary>\r\n\r\n- The tables in this appendix use pipe-delimited Markdown — increase your editor font size or use a Markdown preview for cleaner column alignment\r\n- WCAG 1.4.3 (contrast) and 1.4.11 (non-text contrast) are the criteria most relevant to your daily experience — bookmark them\r\n- When checking contrast ratios, use the WebAIM Contrast Checker link in Section 10 with your browser zoom set to your preferred level\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Sighted users</summary>\r\n\r\n- The POUR table in this section is your one-glance cheat sheet — scan the Example Failure column to see what each principle looks like when violated\r\n- Conformance level badges (A, AA, AAA) appear in the Level column of the Section 3 tables — AA rows are your primary targets\r\n- Bookmark the ARIA Authoring Practices Guide link in Section 10 for live interactive pattern demos\r\n\r\n</details>\r\n\r\n\r\n## 2. Conformance Levels: A, AA, AAA\r\n\r\n| Level | Requirement | Who targets this |\r\n| -------  | -------------  | -----------------  |\r\n| **A** | Minimum accessibility - the baseline that removes the most severe barriers | Required by most accessibility laws |\r\n| **AA** | Enhanced accessibility - removes significant barriers | Required by WCAG 2.2 compliance targets, most government and enterprise standards, GitHub's own accessibility commitment |\r\n| **AAA** | Highest level - removes remaining barriers for the most niche cases | Not universally required; applied where feasible |\r\n\r\nMost open source projects, and GitHub itself, target **WCAG 2.2 AA** compliance. When you file an accessibility bug or review a PR, AA is the standard to reference.\r\n\r\n\r\n## 3. Key Success Criteria for Web Contributions\r\n\r\nThese are the criteria you will most commonly encounter when contributing to web projects or reviewing GitHub interface changes.\r\n\r\n### Perceivable\r\n\r\n| Criterion | Level | What It Requires |\r\n| -----------  | -------  | -----------------  |\r\n| **1.1.1 Non-text Content** | A | All images, icons, and non-text content have a text alternative (`alt` attribute, `aria-label`, etc.) |\r\n| **1.3.1 Info and Relationships** | A | Structure conveyed visually (headings, lists, tables) is also conveyed programmatically |\r\n| **1.3.2 Meaningful Sequence** | A | Reading order makes sense when CSS is removed |\r\n| **1.3.3 Sensory Characteristics** | A | Instructions do not rely solely on shape, color, or position (\"click the green button\" fails this) |\r\n| **1.4.1 Use of Color** | A | Color is not the only means of conveying information |\r\n| **1.4.3 Contrast (Minimum)** | AA | Text has at least 4.5:1 contrast ratio against its background (3:1 for large text) |\r\n| **1.4.4 Resize Text** | AA | Text can be resized up to 200% without loss of content or function |\r\n| **1.4.10 Reflow** | AA | Content reflows at 400% zoom without horizontal scrolling |\r\n| **1.4.11 Non-text Contrast** | AA | UI components and graphical objects have at least 3:1 contrast |\r\n\r\n### Operable\r\n\r\n| Criterion | Level | What It Requires |\r\n| -----------  | -------  | -----------------  |\r\n| **2.1.1 Keyboard** | A | All functionality is available via keyboard |\r\n| **2.1.2 No Keyboard Trap** | A | Keyboard focus can always be moved away from any component |\r\n| **2.4.1 Bypass Blocks** | A | A mechanism to skip repeated navigation (skip link) |\r\n| **2.4.2 Page Titled** | A | Pages have descriptive titles |\r\n| **2.4.3 Focus Order** | A | Focus follows a logical sequence |\r\n| **2.4.4 Link Purpose** | A | Link text describes the destination (\"Read more about issues\" not just \"Read more\") |\r\n| **2.4.6 Headings and Labels** | AA | Headings and labels describe their topic or purpose |\r\n| **2.4.7 Focus Visible** | AA | Keyboard focus indicator is visible |\r\n| **2.4.11 Focus Appearance** | AA *(2.2 new)* | Focus indicator meets minimum size and contrast |\r\n| **2.5.3 Label in Name** | A | For controls with visible labels, the accessible name contains the visible text |\r\n\r\n### Understandable\r\n\r\n| Criterion | Level | What It Requires |\r\n| -----------  | -------  | -----------------  |\r\n| **3.1.1 Language of Page** | A | The default language is identified in the HTML (`lang` attribute) |\r\n| **3.2.1 On Focus** | A | Receiving focus does not trigger unexpected context changes |\r\n| **3.2.2 On Input** | A | Changing a setting does not cause unexpected changes unless the user is warned |\r\n| **3.3.1 Error Identification** | A | Input errors are identified and described in text |\r\n| **3.3.2 Labels or Instructions** | A | Labels or instructions are provided when user input is required |\r\n| **3.3.3 Error Suggestion** | AA | When an error is detected, suggestions for correction are provided |\r\n\r\n### Robust\r\n\r\n| Criterion | Level | What It Requires |\r\n| -----------  | -------  | -----------------  |\r\n| **4.1.1 Parsing** | A | HTML/markup does not have errors that break AT interpretation |\r\n| **4.1.2 Name, Role, Value** | A | All UI components have accessible names, roles, and states that can be programmatically determined |\r\n| **4.1.3 Status Messages** | AA | Status messages (e.g. \"item added to cart\") are announced without receiving focus |\r\n\r\n\r\n## 4. ARIA - Roles, States, and Properties\r\n\r\nWAI-ARIA (Accessible Rich Internet Applications) fills the gap between what HTML natively expresses and what complex interactive widgets require.\r\n\r\n### Three categories\r\n\r\n| Category | Purpose | Examples |\r\n| ----------  | ---------  | ---------  |\r\n| **Roles** | What the element *is* | `role=\"button\"`, `role=\"dialog\"`, `role=\"tab\"` |\r\n| **States** | Current condition (can change) | `aria-expanded=\"false\"`, `aria-checked=\"true\"`, `aria-disabled=\"true\"` |\r\n| **Properties** | Stable characteristics | `aria-label=\"Close dialog\"`, `aria-required=\"true\"`, `aria-describedby=\"hint-text\"` |\r\n\r\n### Important rules\r\n\r\n1. **Don't use ARIA if native HTML suffices.** A `<button>` is already a button - adding `role=\"button\"` to a `<div>` is only needed when HTML semantics cannot be used.\r\n2. **All interactive ARIA widgets must be keyboard operable.** Adding `role=\"button\"` means you must also handle `Enter` and `Space` keypresses in JavaScript.\r\n3. **ARIA only affects the accessibility tree.** It does not add visual styling or behavior - it only changes what assistive technologies announce.\r\n\r\n\r\n## 5. ARIA Landmark Roles\r\n\r\nLandmarks let screen reader users jump directly to major sections of a page. GitHub uses these extensively; screen reader users navigate between them with `D` (NVDA/JAWS) or the Rotor (VoiceOver).\r\n\r\n| Role | HTML Equivalent | Purpose |\r\n| ------  | ----------------  | ---------  |\r\n| `banner` | `<header>` | Site-wide header |\r\n| `navigation` | `<nav>` | Navigation links |\r\n| `main` | `<main>` | Primary page content |\r\n| `complementary` | `<aside>` | Supporting content |\r\n| `contentinfo` | `<footer>` | Footer with copyright, links |\r\n| `search` | `<search>` | Search functionality |\r\n| `form` | `<form>` (with accessible name) | A significant form region |\r\n| `region` | `<section>` (with accessible name) | A generic landmark with a label |\r\n\r\nWhen multiple landmarks of the same type appear on a page, each should have a unique `aria-label` so screen readers can distinguish them. GitHub's Issues list page, for example, has multiple `navigation` regions each with distinct labels.\r\n\r\n\r\n## 6. Common ARIA Patterns\r\n\r\n### Accessible Button (when `<button>` cannot be used)\r\n\r\n```html\r\n<div role=\"button\" tabindex=\"0\" aria-pressed=\"false\" onclick=\"toggle()\" onkeydown=\"handleKey(event)\">\r\n  Toggle\r\n</div>\r\n```\r\n\r\n### Accessible Form Field with Error\r\n\r\n```html\r\n<label for=\"username\">Username</label>\r\n<input id=\"username\" type=\"text\" aria-describedby=\"username-error\" aria-invalid=\"true\">\r\n<span id=\"username-error\" role=\"alert\">Username cannot be empty</span>\r\n```\r\n\r\n### Live Region (status announcements)\r\n\r\n```html\r\n<div aria-live=\"polite\" aria-atomic=\"true\">\r\n  <!-- Content inserted here is announced automatically -->\r\n  3 results found\r\n</div>\r\n```\r\n\r\nUse `aria-live=\"assertive\"` only for urgent interruptions (errors). Use `\"polite\"` for non-urgent status updates.\r\n\r\n### Expandable Section\r\n\r\n```html\r\n<button aria-expanded=\"false\" aria-controls=\"details-panel\">\r\n  Show details\r\n</button>\r\n<div id=\"details-panel\" hidden>\r\n  ...content...\r\n</div>\r\n```\r\n\r\nWhen expanded: set `aria-expanded=\"true\"` and remove the `hidden` attribute.\r\n\r\n\r\n## 7. How Standards Apply to GitHub Contributions\r\n\r\nWhen you contribute to an open source project on GitHub, you will encounter accessibility in several contexts:\r\n\r\n### Filing an Accessibility Bug\r\n\r\nReference the specific WCAG criterion. This makes the bug actionable:\r\n\r\n> **Bad:** \"The button isn't accessible.\"  \r\n> **Good:** \"The 'Subscribe' button has no visible focus indicator, failing WCAG 2.4.7 Focus Visible (Level AA). When navigating by keyboard, there is no visual indication of where focus is.\"\r\n\r\n### Reviewing a PR for Accessibility\r\n\r\nChecklist for any PR that touches HTML or UI:\r\n\r\n- Do new images have `alt` attributes?\r\n- Do new interactive elements work with keyboard only?\r\n- Do new form fields have associated `<label>` elements?\r\n- Are any new color-only indicators present?\r\n- Does new dynamic content use `aria-live` if it updates without a page load?\r\n\r\n### Writing Accessible Documentation\r\n\r\nDocumentation in Markdown is converted to HTML. Accessible Markdown:\r\n\r\n- Use heading levels in order (don't skip from H1 to H3)\r\n- Write descriptive link text (not \"click here\")\r\n- Add alt text to images: `![Bar chart showing 40% improvement in task completion](chart.png)`\r\n- Use actual lists (`-` or `1.`) rather than faking them with symbols\r\n\r\n\r\n## 8. Testing Against Standards\r\n\r\n### Automated Tools (catch ~30-40% of issues)\r\n\r\n| Tool | Use |\r\n| ------  | -----  |\r\n| [axe DevTools](https://www.deque.com/axe/) | Browser extension - run on any page, get WCAG violations with criterion references |\r\n| [WAVE](https://wave.webaim.org/) | Browser extension or web service - visual overlay showing issues |\r\n| [Lighthouse](https://developer.chrome.com/docs/lighthouse/) | Built into Chrome DevTools - accessibility audit with scores |\r\n| [IBM Equal Access Checker](https://www.ibm.com/able/toolkit/tools/) | Enterprise-grade browser extension |\r\n\r\n### Manual Testing (catches the rest)\r\n\r\n1. **Keyboard-only navigation** - unplug your mouse; can you do everything?\r\n2. **Screen reader walkthrough** - navigate the feature with NVDA, JAWS, or VoiceOver\r\n3. **200% zoom** - does content reflow without horizontal scrolling?\r\n4. **High contrast mode** - Windows High Contrast or macOS Increase Contrast; are all elements still visible?\r\n5. **Disable CSS** - does the content still make sense in reading order?\r\n\r\n### Learning Cards: Testing Against Standards\r\n\r\n<details>\r\n<summary>Screen reader users</summary>\r\n\r\n- You are the manual test — automated tools catch only 30-40% of issues; your screen reader walkthrough catches the rest\r\n- Install the axe DevTools browser extension (Section 8 table) and run it on any page; results are announced as a list of violations with WCAG criterion references\r\n- When doing a keyboard-only navigation test, press Tab repeatedly and listen — every interactive element should announce its name and role\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Low vision users</summary>\r\n\r\n- The 200% zoom test (item 3) mirrors your daily experience — if content breaks at 200%, file a bug citing WCAG 1.4.4 Resize Text\r\n- Windows High Contrast mode test (item 4) is one click: Settings, Accessibility, Contrast themes — switch and check that all UI elements remain visible\r\n- The WAVE browser extension overlays icons on the page showing errors and warnings — zoom in to read the small annotation labels\r\n\r\n</details>\r\n\r\n<details>\r\n<summary>Sighted users</summary>\r\n\r\n- The Lighthouse accessibility audit (Chrome DevTools, Ctrl+Shift+I, Lighthouse tab) gives a 0-100 score — aim for 90+ on any page you contribute to\r\n- For the keyboard-only test, unplug your mouse and try completing every action — watch for the blue focus ring moving logically through the page\r\n- The automated vs. manual split (30-40% / 60-70%) means green CI checks do not guarantee accessibility — always pair tool output with a quick manual review\r\n\r\n</details>\r\n\r\n\r\n## 9. Quick Reference: What to Check in a PR\r\n\r\n| Check | WCAG Criterion |\r\n| -------  | ---------------  |\r\n| New images have alt text | 1.1.1 |\r\n| Heading levels are in order | 1.3.1 |\r\n| Links have descriptive text | 2.4.4 |\r\n| Interactive elements are keyboard accessible | 2.1.1 |\r\n| Focus is visible on all interactive elements | 2.4.7 |\r\n| Form fields have labels | 1.3.1, 3.3.2 |\r\n| Error messages are descriptive | 3.3.1, 3.3.3 |\r\n| Color is not the only indicator | 1.4.1 |\r\n| Dynamic content updates use aria-live | 4.1.3 |\r\n| New UI components have name, role, value | 4.1.2 |\r\n\r\n\r\n## 10.

+# Agentic Pilot Workflow
+
+This folder contains the repeatable tooling for running a GPT-5.4-assisted transcript workflow one episode at a time without overwriting the committed podcast scripts until you choose to do so.
+
+## Goal
+
+Use the existing podcast pipeline for source extraction, script structure, segment manifests, and metadata tagging, while adding a repeatable human-in-the-loop rewrite workflow for better voice, stronger chapter names, and tighter quality checks.
+
+## Workflow
+
+1. Build the podcast source bundles if the curriculum has changed.
+2. Generate or refresh the baseline transcript for one episode or challenge.
+3. Build a source packet for that slug.
+4. Rewrite the transcript with GPT-5.4 using the packet as source of truth.
+5. Save the candidate transcript in `podcasts/logs/agentic-pilots/`.
+6. Evaluate the candidate transcript against the original lesson source.
+7. When accepted, promote the transcript into `podcasts/scripts/`.
+8. Audit chapter-plan quality across the catalog and refine weak titles.
+9. Regenerate audio and metadata.
+
+## Useful Commands
+
+Generate a single transcript by slug:
+
+```powershell
+npm run generate:podcast-transcript -- --slug ep05-working-with-issues
+```
+
+Generate a range of companion episodes:
+
+```powershell
+npm run generate:podcast-transcript -- --start 5 --end 10 --group chapters
+```
+
+Generate a range of challenge episodes:
+
+```powershell
+npm run generate:podcast-transcript -- --start 1 --end 4 --group challenges
+```
+
+Build the source packet for one slug:
+
+```powershell
+npm run podcast:agentic:packet -- --slug ep05-working-with-issues
+```
+
+Evaluate a candidate transcript against the lesson source:
+
+```powershell
+node podcasts/tools/agentic-pilot/evaluate-transcript.js \
+  --source docs/05-working-with-issues.md \
+  --transcript podcasts/logs/agentic-pilots/ep05-working-with-issues-gpt54.txt \
+  --out podcasts/logs/agentic-pilots/ep05-working-with-issues-gpt54.report.json
+```
+
+Promote an accepted GPT-5.4 pilot into the live script path and refresh its segment JSON:
+
+```powershell
+npm run podcast:agentic:promote -- --slug ep05-working-with-issues
+```
+
+Audit chapter-plan quality across every generated `*-chapters.json` file:
+
+```powershell
+npm run podcast:chapters:audit
+```
+
+Normalize chapter-plan sidecars after a full rebuild to drop generic or overly granular titles:
+
+```powershell
+npm run podcast:chapters:normalize
+```
+
+## Chapter Marker Flow
+
+Transcript generation now writes three artifacts for each selected script:
+
+- the transcript text file in `podcasts/scripts/`
+- the derived segment file in `podcasts/transcripts/*-segments.json`
+- the ordered chapter plan in `podcasts/transcripts/*-chapters.json`
+
+The chapter plan is sequential, not time-based. Each entry stores a chapter title plus a `startSegmentIndex`. Later, `podcasts/tag-audio-metadata.py` converts those ordered segment boundaries into timed ID3 chapters and Podcasting 2.0 chapter sidecars after audio generation. This keeps chapter naming in the transcript layer, where the teaching context is still available.
+
+## What Scales Across All 75 Episodes
+
+- selective transcript generation by slug, range, and group
+- reusable source-packet generation
+- reusable transcript evaluation
+- reusable pilot promotion
+- sequential chapter-plan generation for metadata tagging
+- reusable chapter-plan auditing across the full catalog
+
+The only human-in-the-loop step is the GPT-5.4 rewrite itself. Everything around that step is now scriptable and repeatable across the full catalog.
