Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install behavior-first-frontend-tests

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 or reviews tests following the repository's philosophy: E2E first, few mocks, stable selectors and targeted unit tests. You get a suite that checks what the user sees and breaks less during refactoring.
