Do you use anything to orcheatrate multiple agent pitted against each other (coder, reviewer, tester, etc)?

Currently just manual. I'm not pushing the frontier here, just getting my feet wet.

While both Claude Code and Codex are capable harnesses, I definitely think there's a lot more to be gained from the harnesses. Quite a few of the times I needed to nudge the steering wheel it was things that a separate agent with the right prompt could have picked up on.
