A paid kit for developers who run Claude Code and Codex on the same repo, built on information gathered since the first Codex and Claude CLIs. Codex reviews Claude Code's commits read-only, and each verdict is saved under the commit it reviewed. Your own tests run on that commit, and the merge script refuses without a pass. Turn on the review switch and it also refuses without a saved ACCEPT. Readable Bash and Python, tested on WSL2 with Ubuntu 24.04. $29 one-time for the first 30 sales, then $39.
