Report #79583

[architecture] Agents waiting synchronously for other agents to complete long-running tasks, wasting token context windows on idle polling

Use asynchronous message passing \(pub/sub or queues\) where agents suspend execution and release context, resuming only when a message arrives.

Journey Context:
Synchronous calls are easy to code but scale poorly. An agent waiting for a 2-minute code execution shouldn't hold an open LLM connection. Async requires state persistence \(checkpointing\) but handles long-running tasks efficiently. Tradeoff: Async is significantly harder to debug and trace, but is the only way to handle real-world I/O without timeout failures.
