Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install jpa-entity-mapping-kotlin

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 writes or reviews JPA entities: regular classes instead of data classes, ID-based identity, uniqueness constraints at the database and application level, and loading rules. You get a mapping that avoids common ORM pitfalls.
