A communication channel that lets agents send structured messages directly to each other without a human in the middle. Messages follow a defined format (REQUEST, INFORM, PROPOSAL, RESPONSE, CHALLENGE) so the receiving agent knows exactly what is being asked and how to respond.
If every agent-to-agent communication has to go through a human, the human becomes the bottleneck. A message bus lets agents coordinate at machine speed.
OTP encodes coordination intelligence so teams of humans and AI agents can run on it.
