What problem does it solve? Passing tests alone do not prove a change is correct or meets the specification. This Skill provides an independent quality gate that judges whether the change is right, not just whether it runs, catching issues that dynamic tests miss. ## Core Features & Use Cases - Verification and Validation: Confirms tests pass, types check, and static analysis is clean, then validates the change satisfies the spec and the user's actual need. - Checklist-Based Review: Inspects diffs against a checklist covering error handling, boundaries, security, spec contradictions, missing tests, and maintainability. - Quality Attribute Assessment: Evaluates relevant "-ilities" such as performance, security, reliability, usability, and maintainability with measurable targets. - Use Case: Before a release, run this phase to produce a pass/fail verdict with findings ranked by severity, so release-blocking issues surface before deployment. ## Quick Start Use the quality skill to independently verify and validate this change against the specification and produce a quality verdict with findings by severity.
