Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install jpa-hibernate-performance-pitfalls

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 N+1 queries and lazy loading errors, then suggests JOIN FETCH, @EntityGraph or batch fetching. You get a targeted fix and a way to check the queries in the SQL logs.
