What problem does it solve? Code reviews often become bottlenecks, sources of team friction, or rubber-stamp approvals that miss critical bugs. This Skill provides a systematic review process that catches defects early while keeping feedback constructive and maintaining team morale. ## Core Features & Use Cases - Four-Phase Review Process: Structured workflow covering context gathering, high-level architecture review, line-by-line analysis, and summary decisions with clear verdicts. - Severity-Labeled Feedback: Standardized labels (blocking, important, nit, suggestion, praise) that differentiate must-fix issues from optional improvements. - Language-Specific Guidance: Concrete Python and TypeScript/JavaScript anti-patterns to check, including mutable defaults, broad exception handling, and unhandled async errors. - Use Case: When reviewing a teammate's 300-line pull request, follow the phased checklist to verify security, performance, and test coverage, then deliver prioritized feedback using the comment template. ## Quick Start Review this pull request using the code review checklist and provide feedback with severity labels.
