I sort of have this indirectly solved with a project I'm working on inspired by Beads. One thing I added is as you have the LLM work on tasks, you can sync them directly to GitHub, I would love to add other ticketing / task backends to it, but I mostly just use GitHub. You can also create them on GitHub and sync them down and claim a task (the tool will post a comment on GitHub that you've claimed the work). I can see people using it to collaborate easier, but for the time being it's just me using it for myself. ;)
These tasks become your prompt once refined. I basically braindump to Claude, have it make tasks from my brain dump. Then I tell Claude to ask me clarifying questions, it updates the tasks and then I have Claude do market research for some or all tasks to see what the most common path is to solve a given problem and then update the tasks.
