What problem does it solve? Code changes often reach pull requests without systematic validation, letting type errors, lint violations, failing tests, or security vulnerabilities slip into main branches. This Skill enforces a strict six-phase gate where each phase must pass before the next runs. ## Core Features & Use Cases - Six Sequential Phases: Build, Type Check, Lint, Test Suite, Security Scan, and Diff Review, each with explicit pass criteria and failure stops. - Verification Report Generation: Produces a structured Markdown report with per-phase status, duration, and coverage thresholds (lines >= 80%, branches >= 70%). - CI Automation: Includes a ready-to-adapt GitHub Actions workflow that runs all phases on pull requests. - Use Case: Before opening a PR for a new authentication feature, run the loop to confirm the build compiles, types are strict-clean, tests meet coverage thresholds, no secrets are hardcoded, and the diff stays under 400 lines. ## Quick Start Run the full verification loop on my current branch and generate a verification report before I open the pull request.
