Use this skill when the user wants AI work they can trust without watching every step: the AI fixes direction first (rules, assumptions, failing checks sealed in git), builds to green, then proves the result with evidence for the human to review. Trigger when a repo has .add/, the user says "add", "/add", "start a…
