Setup wizard overwrites existing OpenClaw config instead of merging

[taraagentix]

Problem

Running bun run setup (the xopsbot setup wizard) replaces the entire ~/.openclaw/openclaw.json file instead of merging with existing configuration.

Impact

If a user already has a configured OpenClaw agent (e.g., a main orchestrator agent like Tara), the wizard silently removes it and replaces the config with only the xopsbot agents (xops-k8s, xops-rca, xops-finops).

Expected Behavior

The wizard should:

1. Detect an existing openclaw.json config
2. Preserve existing agents (especially if one is marked default: true)
3. Add xopsbot agents to the agents.list array instead of replacing it
4. Warn the user if a conflict is detected

Workaround

After running the setup wizard, manually re-add the original default agent to ~/.openclaw/openclaw.json and update the subagents.allowAgents array to include the xopsbot agent IDs.

Reproduction

1. Configure OpenClaw with a custom default agent
2. Run bun run setup from the xopsbot directory
3. Check ~/.openclaw/openclaw.json — original agent config is gone

Environment

• OpenClaw version: latest
• xopsbot version: 0.1.0
• OS: macOS (Darwin 24.3.0 arm64)
