Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install claude-code-harness-testing

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 installs vigiles, picks the cheapest test tier that is enough, writes the test and runs it. For example, it checks that a hook fires or blocks, that a skill triggers, or that injected context reaches the agent, and it can observe a run.
