Apply RAG to your tool catalog — semantic search over tool descriptions improves selection accuracy ~3×

Digital Applied·medium signal

Rather than injecting all tool definitions into context, index them and retrieve only the semantically relevant ones per query, which roughly triples tool-selection accuracy by removing distractor tools from the window. This is the cheap, framework-agnostic version of Tool Search you can build yourself with an embedding index. It compounds with description rewriting: clean descriptions also embed better.
