Claudex Loop: Claude and Codex check each other's work

One model writes the plan and the other pokes holes in it until it holds up, then they swap roles so whoever wrote the code never grades it.

Step by step

  1. Open the GitHub repo and read the README.
  2. In Claude Code: /plugin marketplace add chaseai-yt/claudex-loop, then /plugin install claudex-loop@claudex-loop. For Codex, copy the skills folder as the README shows.
  3. Make sure both Claude Code and Codex are installed and signed in, plus Python 3.10 or newer.
  4. Try it on a feature: "claudex this feature: plan and implement it", then read PLAN-REVIEW-LOG.md to see what the second model caught.

Watch out for

Uses both your Claude and your Codex plans, and each review round costs time and tokens. Lower the rounds setting for small jobs.
