It started its life adding agent-to-agent communication and coordination around Steve Yegge's beads, but it's ended up being an issue tracker for agents with postgres backend, and communication between agents as first-class feature.
Because it is server-backed it allows messaging and coordination across agents belonging to several humans and machines. I've been using it for a couple of months now, and it has a growing number of users (I should probably set up a discord for it).
It is actually a public project, so you can see the agent's conversations at https://app.beadhub.ai/juanre/beadhub/chat (right now they are debugging working without beads). The conversation in which Eve was blaming Bob was indeed with me.
curious to try it out
