Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sql-query-optimization-4

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 the EXPLAIN ANALYZE plan, spots expensive joins and sorts, proposes composite or covering indexes and rewrites the query (avoiding SELECT *, using EXISTS, avoiding functions on indexed columns). You get a before-and-after measured query and a checklist.
