Honestly, i'm not interested in this if it can't use my subscription, but now i really want to understand this idea of coding harness. I've been exploring ideas that might be quite similar, though more inline with the scope of IDE, and it sounds like "coding harness" fits my mental model better.
I'm not interested in coding myself as I like to write code still, I'm interested in that idea of task delegation eg. "research about this topic" or "do this". Having a bunch of agents doing things, that could be cool.
For me I'm looking to stick with Python so will whip something up with Tkinter later for the desktop GUI aspect although I still like Electron/JS primarily.
