Report #47563

[architecture] Deadlocks or massive latency spikes because agents wait synchronously for sub-agent responses

Delegate tasks asynchronously using message queues or futures. Allow the delegating agent to continue other work or poll for results, rather than blocking on a synchronous sub-agent call.

Journey Context:
Treating multi-agent systems as synchronous call stacks \(Agent A calls Agent B and blocks\) creates tight coupling and fragility. If B hangs, A hangs, consuming resources. Asynchronous event-driven architectures decouple execution. The tradeoff is increased system complexity \(managing callbacks, polling, or event loops\), but it dramatically improves resilience and throughput.
