[synthesis] Multi-agent orchestration deadlocks or cascades into failure when one sub-agent hangs or returns an unexpected format

Implement asynchronous, message-passing architectures with strict timeouts and fallback schemas \(e.g., Pydantic validation with default values\) for inter-agent communication, rather than synchronous RPC-style calls.

Journey Context:
In frameworks like CrewAI or AutoGen, agents often call each other synchronously. If Agent A calls Agent B, and Agent B gets stuck in a loop or returns a malformed JSON, Agent A hangs indefinitely or crashes. The orchestrator then crashes. This is a classic distributed systems failure mapped onto LLMs. Treating LLM calls as reliable RPCs is a category error. The synthesis is that multi-agent systems must adopt distributed systems resilience patterns: timeouts, circuit breakers, and schema-validated message queues, assuming that any individual agent is inherently unreliable and prone to hanging.
