Report #8239

[architecture] Agents hallucinating capabilities and accepting tasks they cannot complete, leading to downstream failures

Implement confidence-aware routing by requiring agents to output a structured confidence score \(or binary accept/reject with reasoning\) before executing. The orchestrator should route to the agent with the highest explicit confidence, or fall back to a generalist if all scores are below a threshold.

Journey Context:
Standard routing relies on semantic similarity \(e.g., matching the prompt to an agent's description\). But an agent might match the topic yet lack the specific tool or knowledge to execute. By adding an explicit 'capability check' step where the agent evaluates its fitness for the task, you prevent specialists from confidently stepping outside their domain. The tradeoff is an extra LLM call for the confidence check, but it saves the cost of a long, failed execution path.
