Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install javascript-testing-jest-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 the test infrastructure, writes unit, integration and end-to-end tests, and isolates dependencies with mocks and fixtures. It can also follow a TDD or BDD workflow.
