Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install supabase-rls-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 reviews RLS policies, checks how the service key is used and verifies isolation between tenants. You get a ranked list of flaws and the fixes to apply.
