This seems very interesting, but I think the interface choice is not good. There would have been much less friction if this was purely a GitHub/GitLab/etc bot.
I disagree, having used Sweep extensively, I've found the GitHub Issue -> PR flow to be incredibly clunky with a lack of ability to see what is happening and what has gone wrong.
I see where you're coming from and I do plan to add a web UI and plugin/integration options in the future.
I personally wanted something with a tighter feedback loop that felt more akin to git. I also thought that simplifying the UI side would help me stay focused on getting the data structures and basic mechanics right in the initial version. But now that the core functionality is in place, I think it will work well as a base for additional frontends.
