Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install red-green-refactor-tdd

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 a failing test, checks that it fails for the right reason, then adds the minimal code to make it pass. It reruns the full suite before refactoring.
