Code Review (Production-Focused)

A code review checklist that catches what standard lists miss. Standard reviews cover tests, naming, style, error handling, and complexity — those are table stakes. This checklist focuses on five production-breaking categories that most reviews skip.

Inspired by Jake Lundberg's "The Code Review Checklist I Actually Use".

When to Use

• Any code review or PR review
• When asked to "review this code", "review PR #N", or "check before merging"
• As a mental checklist even for quick scans
