Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mockito-service-layer-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 creates tests for @Service classes using @Mock and @InjectMocks, follows the arrange-act-assert pattern, tests exception scenarios and verifies calls to collaborators. The tests stay fast, with no Spring container or database.
