Install with the CLI

In a terminal, from the folder you want:

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

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 first, then the minimal code that makes it pass, then refactors. It works in small vertical slices and tests visible behavior. You get a feature covered by precise tests.
