Report #38482

[architecture] Static routing in multi-agent systems sends tasks to the wrong specialist, causing infinite loops of handoffs

Implement confidence-aware routing where the router outputs a probability or score, and low-confidence routes fall back to a generalist or prompt the user for clarification instead of guessing.

Journey Context:
A common failure mode is a router agent forced to choose from a list of specialists. If none are a good fit, the LLM still picks one, leading to the specialist immediately handing it back \(ping-pong\). By allowing the router to express low confidence and abort/escalate, you break the loop. The tradeoff is a slightly lower automation rate for tasks on the boundary, but it prevents catastrophic infinite loops.
