Report #84623

[architecture] Router agent blindly delegating tasks to specialized sub-agents without evaluating its own certainty, leading to infinite loops of misrouting

Implement a confidence threshold in the router. If the router's confidence in selecting the right agent is below the threshold, route to a 'clarifier' agent or fall back to a generalist, rather than guessing.

Journey Context:
A common failure mode is the 'ping-pong' effect, where Agent A thinks it's Agent B's job, and Agent B thinks it's Agent A's job. By forcing the router to output a confidence score and defining a fallback, you break the loop. Tradeoff: adds latency for the confidence check and sometimes routes to a slower generalist, but prevents catastrophic orchestration loops and token waste.
