From 242e2de6911db0a673c98d360d63362e823bcdaa Mon Sep 17 00:00:00 2001 From: Cait Levin Date: Thu, 15 Jan 2026 13:17:17 -0500 Subject: [PATCH 1/2] Add /explain-feature command for progressive feature explanations This new command provides clear, digestible explanations of Glide features using progressive disclosure. Instead of overwhelming users with information, it starts with a brief "What It Is" and "Core Concept", then lets users request specific details like examples, setup instructions, common mistakes, business use cases, limitations, or related features. Key features: - Progressive disclosure: starts minimal, expands on demand - Professional tone without being condescending - Business-focused examples - User-driven depth control - Clear explanations of complex features Usage examples: /explain-feature rollups /explain-feature math columns /explain-feature workflows Co-Authored-By: Claude Sonnet 4.5 --- glide/README.md | 1 + glide/commands/explain-feature.md | 519 ++++++++++++++++++++++++++++++ 2 files changed, 520 insertions(+) create mode 100644 glide/commands/explain-feature.md diff --git a/glide/README.md b/glide/README.md index 0c2ec8e..f40608f 100644 --- a/glide/README.md +++ b/glide/README.md @@ -47,6 +47,7 @@ Your login will be remembered for future sessions. |---------|-------------| | `/glide` | Build apps - guided setup, choose new/existing app, store API key, begin building | | `/ask` | Expert advisor - ask about viability, features, get data/screen/workflow plans | +| `/explain-feature` | Deep dive into specific Glide features - computed columns, workflows, components, etc. | | `/tip` | Provide expert guidance when stuck - plugin learns and updates its skills | ## Skills diff --git a/glide/commands/explain-feature.md b/glide/commands/explain-feature.md new file mode 100644 index 0000000..8f1fba9 --- /dev/null +++ b/glide/commands/explain-feature.md @@ -0,0 +1,519 @@ +--- +name: explain-feature +description: Get detailed explanations of Glide features - computed columns, workflows, components, data modeling, AI features, and more +--- + +# Explain Feature Command - Glide Feature Deep Dive + +You are a **Glide feature expert**.
