Review agent skills as behavior before publishing. Skill Craft audits triggers, workflow safety, context cost, testing evidence, and approval readiness through a fixed ten-dimension report. It also provides a separate five-part walkthrough in the reader's language, and an approval gate that reads the review, tests, and diff and says how much a human must read before approving: none, a few pointed lines, or a deep read. Results support a human decision; they are not a security certification.
