That’s kind of where Devin excels. The agent itself is good enough, I don’t even know what model it uses. But it’s hosted and well integrated with GitHub, so you just give it a prompt and out shoots a pr sometime later. You comment on the pr and it refines it. It has a concept of “sessions” so you can start many of those tasks at once. You can login to each of its tasks and see what it is doing or interdict, but I rarely do.

Like most of the code agents it works best with tight testable loops. But it has a concept of short vs long tests and will give you plans as nd confidence values to help you refine your prompt if you want.

I tend to just let it go. If it gets to a 75% done spot that isn’t worth more back and forth I grab the pr and finish it off.
