Claude-skill-registry capability

Check if a specific action is possible and what might be blocking it. Use when asking if you can do something, checking permissions, verifying a capability exists, or troubleshooting why something isn't working. Trigger words: can I, capability, able to, permission, possible, how do I.

Checking Specific Capabilities

Messaging

pgrep -q Samara && echo "Samara: OK" || echo "Samara: Not running"
~/.claude-mind/system/bin/message "test" --dry-run 2>/dev/null

Calendar

osascript -e 'tell application "Calendar" to get name of calendars' 2>&1

Contacts

osascript -e 'tell application "Contacts" to get name of first person' 2>&1

Notes

osascript -e 'tell application "Notes" to get name of first note' 2>&1

Mail

osascript -e 'tell application "Mail" to get name of first account' 2>&1

Bluesky

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

Full Disk Access

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

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
