Supabase Agent Skills: an agent that knows Supabase and Postgres
A Supabase task usually spans the database, auth, storage and server functions at once, and an agent can get any one of them wrong. Here Supabase itself ships two skills: supabase covers every product, the client libraries and the CLI, while supabase-postgres-best-practices adds Postgres guidelines in eight categories ranked by impact.
The supabase skill covers Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron and Queues in one place
Helps with supabase-js and @supabase/ssr in Next.js, React, SvelteKit, Astro and Remix, including sessions, JWT and cookies
Works with the Supabase CLI and MCP server, schema migrations, security audits and the pg_graphql, pg_cron and pg_vector extensions
supabase-postgres-best-practices reviews queries, indexes, connection pooling, locking and RLS policies across eight categories
When to use it
You are wiring Supabase Auth into a Next.js app and users lose their session on reload
A table has grown, queries have slowed down, and you need to know which indexes are missing
Before launch you want the schema and Row-Level Security policies checked for gaps
Ask your agent
Set up Supabase Auth in my Next.js app with @supabase/ssr
Look at this table schema and tell me which indexes to add
Write an RLS policy so users can only see their own orders
