Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react-component-testing-vitest

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 sets up Vitest and Testing Library, writes tests with accessible queries, simulates user actions and mocks network calls. You get a readable test suite and common pitfalls avoided.
