Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install avoid-test-anti-patterns

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 reviews tests to find assertions on mocks, methods added only for tests and mocks that were not properly understood. You get tests that check the code’s real behavior.
