Report #34969

[architecture] High latency and hallucinated routing from using an LLM to decide which agent handles a task

Use deterministic routing \(rule-based, intent classification via embeddings, or regex\) for agent dispatch. Reserve LLM-based routing only for highly ambiguous tasks where traditional classifiers fail.

Journey Context:
Using an 'Orchestrator LLM' to read a prompt and decide which agent to invoke adds an entire LLM round-trip \(often seconds\) and introduces non-determinism: it might route to the wrong agent. Intent classification via embeddings or fast rule-based dispatch is orders of magnitude faster, cheaper, and 100% reliable for known intents. LLM routing should only be the fallback, not the default.
