Diagnose a failing CI run, apply the code fix, commit it, push, and watch the re-run until it passes or fails -- the full fix-and-retry loop in one shot. Use after a pipeline fails and the user says "fix it and retry", "fix the CI and push", or "make CI green". Do NOT use for a read-only investigation that stops at a recommendation (use diagnose-ci); do NOT use for a routine commit unrelated to a CI failure (use ship).
