Install with the CLI

In a terminal, from the folder you want:

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

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 your tests to find those that check mocks instead of real behavior, test-only methods leaking into production code and incomplete mocks. You get a list of fixes, with TypeScript and Python examples.
