What problem does it solve? Manual code review often misses critical bugs, security risks, and regression issues, or produces vague feedback that is hard to act on. This Skill structures the review process so every finding is severity-ranked, located, and paired with a minimal actionable fix. ## Core Features & Use Cases - Severity-First Findings: Classifies issues as Critical, High, Medium, or Low, each with file location, root cause, impact scope, and a minimal fix suggestion. - Regression Risk Analysis: Systematically checks boundary conditions, concurrency and async behavior, null and exception paths, and configuration compatibility. - Test Coverage Check: Verifies whether tests were added or updated and identifies missing critical test cases. - Use Case: Paste a git diff or list of changed files before merging a PR, and receive a structured report with findings, open questions, a change summary, and suggested tests. ## Quick Start Review this git diff for bugs, security risks, and missing tests, and list findings by severity.
