Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sql-query-performance-tuning-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 spots the anti-patterns in a query, suggests indexing strategies and rewrites, and proposes a schema change if needed. It relies on how PostgreSQL, MySQL or SQL Server execute the query.
