Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install composition-over-inheritance-demeter

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 reviews the structure of your modules against four principles: composition over inheritance, the Law of Demeter, Tell Don't Ask and encapsulation. It translates each one to your paradigm, object-oriented or functional, with examples in Elixir and TypeScript.
