| name | supabase-test-harness |
| description | Supabase test harness patterns including local Supabase setup, test user creation via Auth Admin API, RLS testing, migration testing (db_reset), seed sequences, rate limiting, and environment detection. Use when setting up Supabase testing infrastructure, creating test users, troubleshooting Supabase test failures, or implementing RLS validation. Triggers on: supabase test setup, test user creation, supabase local testing, RLS testing, migration testing, supabase test harness, auth test helpers. |
