The Tool Routing mechanism selects tools by performing similarity matching between the semantic representation of user intent and the embedding vectors of tool descriptions, so the quality of a tool's natural language description directly affects the agent's decision-making accuracy.

UnverifiedThe tool routing mechanism first uses embedding vector retrieval or a classifier to pre-judge user intent, narrowing the candidate tool pool to 3–5 options, which are then passed to the LLM for precise selection, similar to the recall-ranking two-stage architecture of a search engine.77% similarUnverifiedThe tool-calling capability of intelligent agents allows language models to determine whether a tool needs to be called, generate call parameters conforming to the API specification, and continue reasoning based on the execution results.75% similarUnverifiedThe key breakthrough in tool-calling capability lies in the model's ability to generate structured function-call requests and correctly parse tool return results before continuing to reason, rather than simply concatenating tool outputs into the prompt74% similarVerifiedThe Tool Use protocol introduced by Anthropic excels in parallel multi-tool invocation and nested tool chains.73% similarVerifiedThe quality of a tool's description directly determines whether the model can select the correct tool; vague descriptions cause the model to call the wrong tool or pass incorrect parameters.73% similar
