This is a structured framework for doing code reviews that don't suck. It gives you checklists for correctness, maintainability, performance, and security, plus thresholds for when code is too complex (cyclomatic complexity over 20 means refactor required). The best part is the hard data on review effectiveness: PRs under 400 lines catch the most defects, while anything over 800 lines loses 90% effectiveness. It includes a comment severity system (blocking, major, minor, question) so you're not wasting time debating semicolons while missing actual bugs. Works with any language and integrates with github-agile for PR workflows. Honest take: the metrics and thresholds alone make this worth using as a reference, even if you don't follow it religiously.
