/ClauDex is a fun plugin and command to make the two models pair code — Claude writes, Codex reviews read-only, iterate to consensus.

OpenAI brought them together. ClauDex makes them collaborate instead of just coexist: /claudex runs a write > review loop (Claude implements, Codex reviews the diff via codex exec --sandbox read-only, iterate to consensus, max 3 rounds), and then /claudex:verdict has both models review the same diff independently and surfaces where they disagree.

At the end it returns: “built/reviewed/edited with love by ClauDex ”
In case you haven’t installed Codex, it returns “It takes two to ClauDex. Claude is here — Codex is not, so this would be built with love by Claude alone, and that’s not the deal.”

Open source if anyone wants to try it: /hamza-ali-shahjahan/claudex

All the best!

Hi. Can you share the plugin with me and how to use instructions?
