Checking Specific Capabilities

Messaging

grep -q "bluesky" ~/.claude-mind/system/config.json && echo "Bluesky: Configured" || echo "Bluesky: Not configured"

Full Disk Access

bash
ls ~/Library/Messages/chat.db 2>/dev/null && echo "FDA: OK" || echo "FDA: Missing"

Troubleshooting Flow

  1. Identify the capability: What action is being attempted?

  2. Check prerequisites:

    • Is the required app/service running?
    • Are permissions granted?
    • Is configuration present?
  3. Test minimally: Run simplest possible version of the action

  4. Check logs: Look for error messages

bash
log show --predicate 'process == "osascript"' --last 2m
  1. Report findings: What works, what doesn't, what to fix

Common Blockers

  • "Not authorized to send Apple events": Missing Automation permission
  • "Operation not permitted": Missing FDA or specific permission
  • "Application isn't running": Need to launch the app first
  • "No such file": Script or config missing
