Report #86526

[frontier] Flat multi-agent conversations devolving into chaos or circular arguments without clear leadership

Use hierarchical GroupChat topologies with explicit speaker selection functions \(using LangGraph's Send\(\) or AutoGen's GroupChat with custom speaker\_selection\_method\) where a manager agent delegates to workers, rather than round-robin or random speaking orders, enforcing a directed delegation graph

Journey Context:
Early multi-agent systems use democracy \(round-robin\) or random selection, causing context pollution as irrelevant agents chime in and circular debates. The fix imposes organizational hierarchy with selective delegation based on task semantics. Tradeoff: rigidity and potential bottleneck at manager vs coherence and convergence. This replaces flat agent swarms with directed acyclic delegation graphs that mirror organizational structures.
