Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install msw-vitest-playground-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 Vitest tests for playground hooks, pages and components: the @mastra/client-js SDK and React Query run for real, only the network is simulated by MSW, using typed fixtures based on the SDK's response types. It avoids hook mocks and reserves Playwright for journeys across pages.
