Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sql-query-optimization

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 reads EXPLAIN execution plans, proposes suitable indexes and rewrites expensive queries or N+1 access patterns. You get a step-by-step diagnosis and fixes to validate on your database.
