Report #4444

[architecture] How do I route user requests to the right model, prompt, or tool set in an agent system?

Add an explicit routing step: classify the input \(with a small LLM call, cheaper classifier, or rule\), then dispatch to a specialized workflow. Route trivial queries to a small/fast model and hard ones to a larger model.

Journey Context:
Without routing, a single prompt optimized for one query type degrades performance on others and wastes expensive tokens on easy questions. Routing separates concerns, lets you tune prompts per category, and is the natural place to enforce cost/speed tradeoffs. Anthropic recommends it as a core workflow for support triage, model cascading, and any task with clear categories. Keep the classifier simple and measure per-route accuracy; a wrong routing decision is a silent failure.
