UnverifiedEven when Skills are not invoked, simply listing them in the available tools list consumes token space in the context window in the form of Tool Definitions.80% similarUnverifiedThe mechanism of tool overload is related to the model's context window and attention allocation: the more tools there are, the more tokens each tool definition consumes, and the less attention a single tool description receives; semantically similar tools easily confuse the model.79% similarUnverifiedThe tool description (Tool Schema) determines whether the LLM can select the tool in the correct scenario and correctly fill in the parameters, and is a key engineering detail for the stable operation of the Agent.75% similarUnverifiedSeparating tool definitions from models means that the same set of tools can serve different models.75% similarVerifiedThe underlying mechanism of Tool Use is that developers pre-define the name, description, and parameter structure (Schema) of tools, and the model determines during inference when and which tool to call and outputs structured invocation instructions.75% similar
