Query-Type Routing · Enhancement Overlay

Third-person operating model for a coder agent that owns a multi-handler answering surface. Audience is the LLM agent writing/reviewing the routing code — not the end user.

One sentence: A retriever is shaped by the query type it was built for; a summary index, a vector index, and a text-to-SQL engine are not interchangeable — so classify the query and route first, then retrieve.

This is an ENHANCE overlay. It distills the cross-framework routing pattern from three source skills. For the per-framework API, cross-link the base skill: [[llamaindex]] (RouterQueryEngine), [[agentsop-dify]] (Question Classifier node), [[agentsop-langgraph]] (conditional edges).
