Report #25257

[architecture] Router agent dispatches tasks to specialized agents that lack the context or capability to complete them, resulting in silent failures or hallucinations

Require the router to evaluate confidence or require the specialized agent to return a 'cannot handle' structured response, triggering a fallback to a generalist agent or human.

Journey Context:
Routers often act as greedy classifiers, forcing a task into the closest matching agent even if it's a poor fit. The specialized agent then hallucinates a tool call or produces a confident but wrong answer. Implementing a 'reject' option allows the specialist to decline, and the router to fallback. This mirrors microservices circuit breakers.
