Report #39187

[frontier] Keyword-based agent routing sends complex queries to wrong specialized agents causing cascade failures

Use embedding-based semantic routing with runtime few-shot example injection, updating route vectors as new edge cases emerge without code changes

Journey Context:
Traditional routing uses regex or keyword matching which fails on semantic nuance \(e.g., 'cancel my subscription' vs 'cancel my account' requiring different agents\). Semantic Router encodes example utterances as embeddings and routes via vector similarity. When new failure modes appear, operators add the misrouted query to the correct route's example set, updating the embedding space without deploying code. This creates a self-improving routing layer that adapts to domain shifts without engineering intervention, unlike static classification models that require retraining.
