The problem with every single tool in the category that I've come across (e.g. Conductor, Sculptor) is that they assume a single repository. Very rarely in my career working on enterprise software have I been in a situation where all my work was constrained to a single repo. Usually a story or feature spans several repos (whether split between frontend/backend, or a repo-per-service). As an engineer in these situations I never work in isolation considering only one repo -- I work across all of them at once and then prep all the PRs together. I'm not saying this multi-repo approach is good, just that it is the state of the world right now in many cases.
So imo tools like this need to work at a level above a single repo. The agent needs to start by cloning all repos needed for the task, and go from there.
