I looked into beads but I didn't see a way to make it work any better than fossil, and fossil does more stuff. My typical setup is to use the repo as a working directory, the tickets for todo, wiki/forum for conversation. There is also a chat interface, but I haven't tried that with agents yet.
But I love fossil for this. You can create users for all of the agents (or agent roles). The CLI for fossil is just a binary and it compiles nearly everywhere.
+1 over here for agentic fossil. With fossil the "work" is integrated in with the code. Beads separates this out, the beads are instances of work that agents can consume, and they aren't part of the work repo. I could see why you might want this, but I still think that fossil gives you more utility.
