Decentralized Model and Handoff

No central controller: peer agents decide when to handoff, request feedback, or report issues.

Examples by degree of genuineness:

MetaGPT — SOP pipeline with standardized docs as interfaces plus a pub/sub message pool (loosely coupled, but role order is fixed);
group chat AutoGen — shared history + centralized speaker selector;
OpenAI Swarm/Agents SDK — genuinely peer handoff network: control passes by relay, routing is distributed.

What is passed without shared context: task description, confirmed facts & constraints, artifact links — not the full trajectory.

Risk: handoff loops — an upper bound is needed.
