Report #4626

[architecture] Agents broadcast every message to all peers and expect an LLM to route traffic, causing context explosion and crosstalk.

Pick an explicit conversation pattern: sequential chat for handoffs, nested chat for encapsulation, or group chat with a constrained manager and deterministic speaker-selection rules. Avoid all-to-all messaging.

Journey Context:
AutoGen's group chat manager broadcasts each message to every participant; that shared context is powerful but easy to misuse. Teams often default to 'everyone in one room' and then blame the model for poor routing, when the real problem is an underspecified topology. Sequential chats keep context scoped and predictable; nested chats hide sub-workflows behind a single agent. Use LLM-based speaker selection only when the task genuinely cannot be expressed as rules.
