Tmux, nvim, opencode + a load of custom scripts and skills is all I need. I cringe every time I see some colleague daddle around with sth like this or copilot trying to phrase a prompt what should be just a git command. But I might just not be the target audience.

Exactly. Mine is Ghostty + Kakoune + Nushell sprinkled with Apple Script

Can hardly imagine my life without now:

    gtty surface siblings --action auto-accept --keep-alive --offset -1
which accepts first agent's choice and keep `caffeinate` running until ctrl-c. `--offset` has super nice tab autocomplete.

I struggle to imagine having a harness that isn't open source. Maybe one that had a really really really strong plugin system?

But: I want to be able to do some adjustments and scripting of my harness! If all the places to forefit your agency and use some closed proprietary system, I cannot imagine compromising on my harness! My gracious. This is the seat of my agency & there's no way I'm going to yield that up, give that over to some closed solution someone else hands me!

(I also do recommend DIY though, find a good base!)

Would love to hear what features you would like to see added for your workflow.

We would definitely like to support a more modular/extensible UI soon. However, the UI is currently pretty unopinionated and supports most users’ workflows.
