What problem does it solve? Built work often merges without an independent check that it actually satisfies the issue's acceptance criteria, passes CI gates, and respects the product vision. This Skill performs a rigorous, context-independent review of a MellowMaker pull request before merge. ## Core Features & Use Cases - Independent stage verification: Detects shared-context contamination between plan, build, and verify stages and validates stage provenance via a provenance-check script. - Criterion-level evidence review: Fetches the issue, plan comment, and exact PR head, runs repository CI gates locally, and maps every acceptance criterion to concrete file/line or runtime evidence. - Domain risk inspection: Checks vision drift, offline regressions, SQLite data loss, counter integrity, importer resilience, Expo compatibility, accessibility, and test quality, then posts a binary ready/not-ready verdict as a PR review. - Use Case: After a build stage opens a PR for issue #42, run this Skill in a fresh context to confirm the diff meets every acceptance criterion, CI is green, and deferred device smokes are properly logged before merging. ## Quick Start Use the verify skill to review the pull request for issue 42 against its acceptance criteria and post the verdict as a PR review.
