Report #1357

[architecture] Hard-coded routing logic sends tasks to the wrong agent when intent is ambiguous, causing infinite handoff loops

Include a confidence score or fallback mechanism in the routing agent's output schema. If confidence is below a threshold, route to a human or a generalist agent, rather than guessing and triggering a ping-pong loop between specialists.

Journey Context:
A common failure mode is the 'ping-pong' effect: Agent A thinks Agent B should handle it, Agent B thinks Agent A should handle it, and they hand off back and forth infinitely. This happens because routing agents are forced to make a discrete choice among specialists. By requiring the router to output a confidence score and defining a threshold for fallback, you break the loop. The tradeoff is an extra LLM call or slightly more complex routing schema, but it prevents runaway token consumption.
