What does supabase do?

supabase is a Claude skill that guides any task on a Supabase project, from Auth and Edge Functions to Storage, Realtime and schema changes. It tells Claude to check the Supabase changelog and current docs before writing code, to verify each fix with a test query and stop after two or three failed attempts. A security checklist covers traps such as user_metadata in RLS policies, views that bypass RLS, SECURITY DEFINER functions and service_role keys in the browser. For schema work it separates declarative schemas from imperative migrations, then runs supabase db advisors and supabase db pull to produce the migration file.

When should you use supabase?

Use it when

  • An RLS policy hides rows you expected to see
  • You are adding a table and its migration
  • The Supabase MCP server tools do not show up

Skip it when

  • Your project does not use Supabase
  • You only need generic SQL help

What it needs and what it can touch

You need

  • A Supabase project
  • The Supabase CLI (v2.81.3 or later for advisors)

What it can do

  • Runs shell commands (Supabase CLI, curl)
  • Runs SQL on your database
  • Fetches Supabase docs and changelog from the web
  • Reads and edits project files

From reading its instructions, not from running it.
