Report #51349

[architecture] Agent A waiting synchronously for Agent B to complete a sub-task causing deadlocks

Design agent interactions as asynchronous event-driven flows using state machines, rather than blocking RPC calls between agents.

Journey Context:
Treating agents like synchronous functions leads to deadlocks common in traditional concurrency. Asynchronous state machines allow agents to yield control, persist their state, and resume when their requested state or event is achieved, preventing thread/process exhaustion.
