Report #74374

[architecture] Orchestrator agent hallucinates routing decisions, sending tasks to the wrong specialized agent

Replace LLM-based routing with deterministic semantic similarity routing \(embeddings\) or confidence-aware function calling, falling back to a generalist agent if no specialist exceeds a confidence threshold.

Journey Context:
Using an LLM as a router to decide which agent handles a query adds latency and introduces a point of failure where the router misinterprets the task. LLMs are bad at strict classification. By embedding the capabilities/descriptions of specialized agents and comparing them via cosine similarity to the incoming task, routing becomes deterministic, fast, and mathematically grounded. The tradeoff is maintaining accurate embeddings for agent capabilities, but it eliminates the 'router hallucination' failure mode.
