Tips

  1. Always run detection first — Most skills auto-invoke it, but it's faster to run explicitly
  2. Check the context file — If a skill behaves unexpectedly, the context may have stale data
  3. Use the orchestrator for full audits — It handles dependencies automatically
  4. Save reports with dates — Rename supabase-audit-report.md to include the date for history
