Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install java-unit-testing-junit

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 first detects the JUnit version and libraries of your Maven or Gradle project, then follows their conventions. It writes assertions, parameterized tests, Mockito mocks and deterministic tests. It never skips or deletes a failing test, and can set up JaCoCo coverage or PIT mutation testing.
