Supabase

Gives Claude the full Supabase workflow: migrations, RLS policies, Edge Functions, and the local-first CLI setup. You'll want this when you're building anything that touches Supabase's database, auth, or storage. It covers the important stuff like writing RLS policies that don't leak data, linking tables to auth.users properly, and the diff-based migration workflow that keeps you from manually writing SQL when you don't want to. The Edge Functions section shows the Deno runtime patterns with auth context. Good reference for environment variables and connection pooling setup too, which matters for serverless deployments.
