[architecture] Choosing peer-to-peer agent topology without safeguards, leading to circular handoffs and untraceable decisions

Default to an orchestrator \(hub-and-spoke\) topology where a central agent routes tasks. Only use peer-to-peer when agents genuinely need autonomous delegation, and only after implementing handoff limits and cycle detection.

Journey Context:
In orchestrator topology, a central agent routes tasks to specialists and aggregates results. In peer-to-peer, any agent can hand off to any other. Orchestrator is simpler to debug, prevents circular handoffs by construction, and makes control flow explicit. Peer-to-peer is more flexible but introduces circular dependency risks, makes debugging harder \(which agent made which decision?\), and can lead to unbounded handoff chains. CrewAI's hierarchical process and AutoGen's GroupChat manager both implement the orchestrator pattern for these reasons. The common mistake is choosing peer-to-peer for flexibility without implementing guardrails. If your orchestrator becomes a bottleneck, consider domain-sharding \(multiple orchestrators per domain\) rather than switching to flat peer-to-peer.
