Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-suite-effectiveness-review

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 combines a search for surviving mutants in the code and tests with a cold read of the source alone, then checks every finding against the code. You get a list of confirmed gaps in the tests.
