Report #3413

[agent\_craft] Agent always runs full retrieval, burning tokens on questions that are trivial or already in parametric memory

Add a lightweight router that classifies query complexity and branches: no-retrieval direct answer, single-step RAG, or multi-step iterative retrieval. Only load external context when the classifier decides it is needed.

Journey Context:
One-size-fits-all RAG is either wasteful \(simple queries\) or incomplete \(multi-hop queries\). Adaptive-RAG trains a small classifier to pick the cheapest strategy that can answer the query. For agents, you can implement the same logic with a cheap model or heuristics: factual lookup → direct; domain question → RAG; compare/contrast or multi-hop → iterative. This cuts latency and distraction without sacrificing accuracy on hard questions.
