Report #26820

[frontier] Multi-agent systems devolve into chaotic infinite loops or deadlocks when peer agents call each other without shared state

Use an Orchestrator-Worker \(Hierarchical\) topology. A central LLM orchestrator maintains the global state, plans the steps, and delegates to specialized worker agents. Workers return structured results to the orchestrator; they never call each other directly.

Journey Context:
Flat peer-to-peer agent swarms are alluring but fail in production because context gets fragmented, and agents enter 'politeness loops' or duplicate work. Orchestrator-worker centralizes state and decision-making, making debugging possible and ensuring termination. Tradeoff: the orchestrator becomes a bottleneck and single point of failure, but reliability and debuggability gains far outweigh throughput costs in production.
