Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install supabase-rls-key-security

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent separates the anon and service_role keys, enables RLS on every table and hardens the API exposed by PostgREST. It points out that a table without RLS is readable by anyone with the project URL and anon key.
