I see a gap in the ecosystem: too few mature open source harnesses.
I’d like a community led, BYOK, modular project where I can define, orchestrate, monitor and maintain agents.
Of course this is a new area and projects like this take time. But still, IMHO, a gap exists.
Unless someone wants to recommend their favorite FOSS tool; please do.
I use opencode as my harness which is pretty ok. I daily drive it with no issues. It's not going to do any orchestration for you but it works.
I'm slowly moving to Pi but it's a very DIY system. Think neovim for agents. I think it has the potential to be where I end up for a while but it's a long road.
