I Made Claude Code and Codex Argue About My Code Until They Agreed

I used Claude Code and Codex to create a loop where Claude reviews its own code until it passes, and it found several real bugs in the process. This shows the value of adversarial review and the importance of verifying assumptions. To apply this, create a loop where a reviewer checks the code and evidence, and only marks it as done when a fresh round finds nothing new. This can be done using a tool like Claude Code and Codex.
