He Runs Claude Code and Codex as ONE System (You Can Too)

The last four minutes are the part to steal: three things you can do in 20 minutes to get most of it. Sjoerd Tiemensma is my co-founder at Autonomee, and he has been running Claude Code and Codex side by side ever since they came out. Not switching between them. Running them as one coordinated system. He built an MCP server that lets separate model sessions discover each other and pass messages back and forth. Git worktrees so two agents build in parallel without stepping on each other. A session near a full context window hands off to a clean one and keeps going. Opus 5 on max reasoning does the UI work, Codex handles computer use, Fable orchestrates the whole thing. If you want to build this kind of setup alongside people who are actually running it, that is what Autonomee is. Hundreds of professionals building their AI Systems, and weekly calls where Sjoerd and I show what we tested that week.
