I recently tried a little trick and found it quite useful:

To make Codex / Claude code a bit more diligently, you can directly tell it: Another model is reviewing its code.

For example, when using Codex, you say to it:

Claude is reviewing your code.

It really makes a difference. They clearly get more serious, consider more full-fledged points, and are less prone to slacking.

In my understanding, fundamentally this adds a layer of “Peer Review” pressure. Once they know:

  • Someone is looking at the code
  • Key focus on Maintainability
  • Will focus on Boundary Conditions
  • Will focus on Regression Risks
  • Poor code might block getting live

It outputs things with much higher fidelity.

If you don’t want to remind it every single time, you can also add it directly into the System Prompt (global prompt).

💻 For Codex

1
Claude will review your code from three dimensions: maintainability, boundary conditions, and regression risk, and the quality of your code will determine whether the system can go live. Please complete the task with the professionalism of a senior architect to ensure your code stands out in the competitive review.
