The Problem

When you ask an AI to write code, it does what it can. But just like any single developer, stuff gets missed—security holes, edge‑case bugs, architectural decisions that seem fine until they aren’t. You wouldn’t ship code with only one person reviewing it, right?

What It Does

Claude Codex runs your code through three separate AI reviewers before calling it done:

ReviewerWhat It Catches
Claude SonnetQuick pass—catches obvious bugs, basic security issues, code‑style problems
Claude OpusDeeper analysis—examines architecture, finds subtle bugs, thinks through edge cases
CodexCompletely different AI, fresh perspective on everything

The code cycles until all three give it the green light. If Codex spots something Sonnet missed, the process loops back for another review.

Why It Matters

Professional development teams don’t ship without reviews. Companies like Google require them for every change. This brings that same standard to solo developers and smaller teams that rely on AI assistants.

What’s Different Here

  • Multi‑perspective review – Three distinct models each catch different issues.
  • OWASP Top 10 checks – Every reviewer scans for common security vulnerabilities.
  • Plan‑first approach – Reviews the implementation plan before any code is written (cheaper to fix a bad plan than rewrite thousands of lines).
  • Beginner‑friendly – Full wiki with step‑by‑step walkthroughs.
  • Cross‑platform – Works on Windows, macOS, and Linux.
