How Claude and Codex Can Transform Code Reviews
Imagine if two AI models could work together like human programmers. This is now possible with Claude and Codex. Researchers at Cursor have developed a way for these two AI systems to collaborate directly. By acting as pair programmers, they can provide feedback on each other’s work, making the coding process smoother.

This multi-agent workflow mimics how human teams operate. In this setup, one AI acts as the main worker while the other serves as a reviewer. This approach allows for more effective communication between the two agents, leading to better outcomes in coding tasks.
Improving Feedback Loops
The team behind this innovation found that when Claude and Codex reviewed code together, they often provided different feedback. However, when they agreed on a point, it became a strong signal for developers to address. This collaborative method enhances the quality of code reviews while also speeding up the feedback loop.

Future of Agentic Workflows
The future may see more workflows resembling teamwork rather than automated processes. As AI models improve, their ability to interact will likely become more sophisticated. This shift could lead to significant advancements in how develope
rs approach coding tasks.
Key takeaways
- Claude and Codex can collaborate like human programmers.
- The `loop` tool speeds up feedback loops during code reviews.
- Effective communication between AIs leads to better coding outcomes.
- Future workflows may resemble traditional teamwork more closely.
- Considerations around human involvement remain crucial for success.
Many users are adopting multi-agent systems for various reasons. They seek different perspectives or want to avoid vendor lock-in by using open-source projects. As these systems evolve, treating agent-to-agent communication as a core feature will become increasingly important.
