Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-driven-development-workflow-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

The agent follows the red, green, refactor cycle: write a test that fails, confirm the failure, write the minimal code, then clean up. It also applies criteria for writing good tests.
