Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install supabase-deep-diagnostics

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 queries pg_stat_statements for slow queries, pg_locks and pg_stat_activity for locks and connections, then examines RLS policies, Edge Function cold starts and Realtime drops. You get diagnostic SQL and an evidence file for support.
