What problem does it solve? Code reviews of Redux state changes, refactors, and skill documentation often rely on subjective judgment, letting derived state, duplicate utilities, and pass-through wrappers slip through without verifiable evidence. ## Core Features & Use Cases - Seven-Gate Review Sequence: Enforces instruction compliance, refactor cleanup, utility reuse, state integrity, canonical ownership, automated validation, and semantic checks on every diff. - Evidence-Based Acceptance: Requires commands, exit codes, and search results in every verification report instead of shallow approvals. - Automated Gate Selection: Maps diff scope to required checks such as git diff --check, npm run validate:architecture, npm test, npm run build, and npm run validate:release. - Use Case: When a teammate moves a Redux slice and adds a new selector, run this gate sequence to confirm no pass-through wrapper remains, the selector derives values from canonical state, and architecture validation passed. ## Quick Start Review the current git diff against the verifier quality gates and produce a report citing the instructions checked, gate commands run, and any blockers.
