Report #41588

[frontier] Centralized agent orchestrator becomes bottleneck and single point of failure in production multi-agent systems

Adopt decentralized Agent Mesh topology using A2A \(Agent2Agent\) protocol and MCP resource discovery, where agents dynamically form task-specific coalitions via capability advertisements without a central hub.

Journey Context:
Supervisor patterns \(centralized orchestrators\) collapse under scale and create tight coupling between agents. The frontier pattern \(emerging 2025\) uses DNS-SD or MCP discovery for agents to advertise capabilities \(e.g., 'I can analyze PDFs'\), then form ephemeral coalitions via A2A protocol for specific tasks. Tradeoff: eventual consistency in coordination vs. resilience and horizontal scale. This replaces the 'orchestrator with tools' pattern with peer-to-peer agent networks.
