Evaluate Skill

Operate Caliper: run a skill's eval, read what the results say, and trace each failure to the place that fixes it.

Prerequisites

The caliper CLI must be on PATH. This skill can be copied into an agent without the Caliper repo, so install it if missing:

pipx install caliper-eval

caliper <command> --help is the authority on flags. REFERENCE.md covers the full spec format, engines, and what the results mean.

The four questions

A skill eval answers four separate questions. Each has its own measurement and its own fix location, so keep them apart: a blended number hides which half broke.
