Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install supabase-common-mistakes

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 your Supabase code and ranks mistakes by severity: security, data integrity and performance. For each one it shows the faulty code, why it fails and the correct pattern. You get a prioritised review.
