What problem does it solve? Code merged without structured review accumulates defects, security vulnerabilities, and architectural debt. This Skill enforces a consistent multi-axis review process so every change is evaluated against the same quality gates before entering the main branch. ## Core Features & Use Cases - Five-Axis Review: Evaluates every change for correctness, readability, architecture, security, and performance with concrete checklists per axis. - Severity-Labeled Findings: Categorizes feedback as Critical, Required, Nit, Optional, or FYI so authors know what must be fixed versus what is optional. - Change Sizing and Dependency Discipline: Enforces small reviewable changes, separates refactoring from feature work, and requires changelog review plus per-package isolation for dependency upgrades. - Use Case: Before merging a pull request that adds a new API endpoint, run this review to verify tests cover edge cases, inputs are validated at boundaries, no N+1 queries exist, and the change description stands alone in version control history. ## Quick Start Review the current uncommitted changes across correctness, readability, architecture, security, and performance, and report findings with severity labels.
