What problem does it solve? Code reviews often rely on reviewer intuition, producing inconsistent feedback and missed defects. This Skill replaces impressions with a structured, aviation-style preflight checklist of concrete pass/fail checks, so every review covers the same critical ground regardless of reviewer experience. ## Core Features & Use Cases - Sequential phased checklist: Nine phases from pre-takeoff gates (build, tests, lint, secrets) through architecture, security, concurrency, contract alignment, accessibility, and post-merge verification, where Phase 1 gates everything else. - Stack-specific extensions: Additional check items for dotnet, react, ts, azure, cosmos, and mcp projects are merged into the relevant phases automatically based on project configuration. - Structured findings format: Every FAIL is reported with severity, location, evidence, impact, fix, and false-positive notes, so findings are actionable rather than vague. - Use Case: Before approving a pull request that touches both a .NET API and a React frontend, run the checklist to verify layering rules, test anti-patterns, client-server contract alignment, and accessibility items, then sign off only when all phases pass. ## Quick Start Review the current pull request using the code review checklist and report every failing item with its severity, location, and suggested fix.
