Report #59427

[architecture] Router agent sends a task to a specialized agent that lacks the context or capability to handle the specific edge case, failing silently or hallucinating

Implement confidence-aware routing where the specialized agent evaluates its ability to handle the task and can explicitly reject/escalate back to the router.

Journey Context:
Static routing assumes the router is omniscient. But LLMs are probabilistic. If an agent gets a bad prompt, it tries anyway, leading to garbage outputs. Tradeoff: adds an extra LLM call for confidence assessment, increasing latency and cost, but prevents catastrophic downstream failures. Alternative: complex router prompts, which eventually hit context limits and fail on edge cases.
