What problem does it solve? Code reviews often miss subtle defects or drown in style nitpicks. This Skill structures the review of a change set so that behavior-breaking defects, security weaknesses, and missing tests are surfaced with evidence before any summary. ## Core Features & Use Cases - Evidence-backed findings: Traces control flow and data flow in the changed files and reports each issue with severity, file/line location, impact, and a minimal fix direction. - Risk-prioritized scope: Focuses on defects that change behavior, lose data, weaken authorization, leak secrets, or break compatibility, while skipping style-only or hypothetical concerns. - Test gap analysis: Checks whether the highest-risk behaviors and failure modes are covered by tests without demanding duplicate test layers. - Use Case: After implementing a new API endpoint, ask for a review of the diff to catch an unhandled error path and a missing authorization check before merging. ## Quick Start Use $code-review-and-quality to review my latest changes and report findings by severity with file and line locations.
