Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-first-development-loop-3

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

This skill guides the agent through the red, green, refactor cycle: a test first, then the minimal code to make it pass. It sets out what a good test is, where tests go, the anti-patterns and the rules of the loop. You get tests that check the code's public behaviour rather than its internals.
