A shared handoff file is better than implicit coordination. The problem to watch out for is the file becoming out of date: agent A reads Agents-Collab.md, agent B updates it mid-task, and agent A continues to act on what it has read. The protocol is only as good as how fresh each agent is on the file that contains it. "Live" is the hard part when two agents run at once instead of handing off one after the other. If each agent had a version or timestamp that they checked before they acted, it would stop a handoff written after A's last read from being ignored.
