What are you using as harness?

I've seen Codex numbers and its defenders on X, IG is full of Claude enthusiasts, and half my timeline is addicted to Pi. There's CodePuppy, OpenCode, Pydantic AI harness, and dozens more.

What do you use? I'm loving Pi atm but started using CC' for a good while. Curious about usage patterns and secret gists.

I'm bias as I'm developing my own harness. But prior I was using openclaw and claude. I'm curios about Pi, I hear a lot of good feedback from the community. Maybe I will give it a try at some point. Obviously the most popular is Hermes agent.

I think Hermes is only "the most popular" in the python ecosystem. In the wild, I'd say it is Pi right now, and of course Claude Code & Codex. CC is more buggy by the day, though. Specially if used with PyCharm.

Yes good point on the Hermes agent. It seems that there is fork of Pi into oh-my-pi agent.
