[architecture] Implementing peer-to-peer agent communication without a central coordinator, resulting in chaotic workflows and impossible debugging

Use a hub-and-spoke \(orchestrator\) topology for most multi-agent systems. Let a central orchestrator agent manage context, delegate tasks, and synthesize results; restrict peer-to-peer communication.

Journey Context:
P2P agent networks sound elegant and decentralized, but lead to uncontrolled token consumption, duplicated work, and spaghetti interactions. An orchestrator maintains global context and routes tasks. Tradeoff: The orchestrator becomes a bottleneck and single point of failure, and its context window can fill up. P2P is only justified for highly decentralized, asynchronous tasks where agents must negotiate directly.
