Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-value-evidence-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 starts from the identified diff or commit, finds the entry points and related tests, then looks for proof that a test fails on the faulty behavior. It does not run untrusted code and publishes nothing.
