Hamel Husain shows how to use OpenAI's Codex as an automatic code reviewer for Claude. Claude writes the code, Codex flags bugs and security issues, then Claude fixes what it agrees with. Two models catch more mistakes than one working alone.
If you are writing code with AI, you might have noticed that AI isn't great at catching its own mistakes. Here's how you can fix that. I built a free tool that adds a second pair of eyes. You give Claude a task. It writes the code. When it's done, a second AI, Codex from OpenAI, reviews every change. Bugs, missing tests, security holes, all flagged. Then Claude reads the feedback and fixes what it agrees with. These models have different training, in different blind spots. One catches what the other misses. They argue like coworkers. Of everything I've tried, this pairing works the best, and it works with your existing Claude and ChatGPT subscriptions. Comment review, and I'll send you the link.
