What problem does it solve? When a legacy-to-modern page migration fails a verification, E2E, or parity gate, this Skill closes the loop: it detects which gate failed, applies targeted repairs through a migration-fixer agent, and re-runs the gate so the page can continue down the migration pipeline. ## Core Features & Use Cases - Automatic fix-mode detection: Reads the page status and failure reports (verify, e2e, parity) to select the correct repair mode, with manual override via --mode. - State-machine safety: Refuses to run on healthy, flipped, done, or flip-in-flight pages, and redirects gen-failed pages back to generation instead of masking the problem. - Full gate-chain invalidation: After a successful fix, clears stale gate evidence, route preparation, and cascade records so every downstream gate re-runs against the fixed code. - Use Case: A migrated hotel booking page fails its E2E gate. Run the fix command and the Skill locks the page, launches the migration-fixer agent on the e2e report, records the outcome in the tracker, and tells you the exact gate chain to re-run. ## Quick Start Ask the assistant to run fm-fix on the page that just failed its migration gate, for example by saying fix the failed migration gate for the checkout page on the pc app.
