Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install experiment-query-performance-analysis

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 the staff-only debug endpoints with a personal API key to pull the slowest queries, precompute health and cache footprint for production in the US and EU. It interprets the fields and error codes.
