[architecture] Router agent hallucinates and sends tasks to the wrong specialist agent

Require the router to output a structured confidence score alongside its routing choice; if confidence is below a threshold, route to a generalist agent or prompt the user for clarification rather than forcing a specialist handoff.

Journey Context:
Semantic routing relies on embeddings or LLMs to map a query to an agent. LLMs are eager to please and will confidently choose a specialist even for ambiguous inputs, leading to downstream failures where the specialist lacks the tools or knowledge to handle the edge case. By forcing a structured confidence output \(e.g., JSON \{agent: 'coder', confidence: 0.4\}\) and defining a fallback threshold, you prevent cascading failures. The tradeoff is an extra routing step for ambiguous queries, but it avoids the massive cost of a specialist agent spinning its wheels.
