Report #23068

[frontier] Agent uses rigid regex or expensive LLM call for every routing decision in multi-step workflows

Use embedding-based semantic routing: embed task descriptions, compare to agent capability embeddings via cosine similarity \(threshold ~0.7\), with fallback to LLM for low-confidence cases; cache embeddings in memory for the session.

Journey Context:
Routing is often done with LLM \(slow/expensive\) or regex \(fragile\). Middle ground: embed agent descriptions and incoming tasks, use vector similarity for routing. Fast and captures semantic nuance. Use LLM only when confidence is low. This 'semantic router' pattern reduces latency from seconds to milliseconds for routing decisions.
