What problem does it solve? Pull request titles and bodies drift out of sync with the actual branch diff, and stacked PRs published through Mergify often ship with placeholder metadata. This Skill enforces a consistent, CI-validated PR schema so every published PR accurately describes its current diff. ## Core Features & Use Cases - Structured PR schema: Authors PR bodies with required sections (Summary, Review Claim, Review Lane, Review Unit, Safety Invariant, Slice Rationale, Non-goals, Test Plan, Revert Plan) that local validators check against the actual changed files. - Stacked PR management: Coordinates Mergify stack pushes, refreshes machine-managed stack comments, and audits live PR metadata after every restack or force-push. - Visual proof enforcement: Requires screenshots or video with manual inspection notes for UI-impacting diffs before publication. - Use Case: After splitting a large refactor into a stack of reviewable slices, run this Skill to validate each PR body against its diff, publish via node scripts/create-pr.mjs, and repair any Mergify placeholder titles before review. ## Quick Start Ask the AI to create a pull request for the current branch using the repo's preferred PR schema and validate the body against the current diff.
