The 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.

UnverifiedThe same model can perform very differently across different tools; the model determines the system's lower bound while the Harness determines the upper bound of agent performance.80% similarUnverifiedThe more tools there are and the more similar their descriptions, the overall usability of the entire tool chain may actually be lower than a system with fewer but precisely described tools.80% similarUnverifiedToo many tools cause model selection confusion; the current mainstream direction is to provide a small number of tools and let the model iteratively leverage them on its own, or let the model dynamically design tools based on the task (especially by writing scripts).77% similarUnverifiedSeparating tool definitions from models means that the same set of tools can serve different models.76% similarUnverifiedSelective tool loading refers to exposing to the model only the tools actually needed for the current task scenario, which reduces token consumption and decreases model confusion in tool selection.75% similar
