Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-first-development-loop-2

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 discovers the project's test stack, plans the behaviors, writes a first end-to-end test, then moves through red, green and refactor cycles. It tests through public interfaces, with Playwright or Cypress when needed. You get code covered by tests that describe behavior.
