Report #55564

[architecture] Using rule-based keyword matching to route tasks to specialized agents results in brittle routing that fails on phrasing variations

Use an LLM-driven intent classifier for routing, but implement a confidence threshold with a fallback to a generalist agent

Journey Context:
Developers often write 'if refund in query: route\_to\_refund\(\)'. This breaks when users say 'my money was not returned'. An LLM router solves the semantic gap but introduces hallucination risk. If the router is unsure, forcing a route to a specialist yields confident hallucinations. A generalist fallback safely handles ambiguous queries without triggering specialized, irreversible workflows.
