When the number of tools scales to dozens or hundreds, semantic overlap between tool descriptions causes the model to experience selection confusion; when the number of tools is fewer than 10, the model can typically match them accurately.

VerifiedIn the ReAct framework, when the number of tools exceeds 20, both token consumption and the model's tool selection accuracy drop significantly, a problem known as 'tool overload'.79% similarUnverifiedTool parameter descriptions that are too broad cause the model to hallucinate parameters, while descriptions that are too strict limit the tool's applicability and flexibility.76% similarUnverifiedWhen a conversation goes deep into thousands of messages and accumulates more than 2,000 tool calls, a single small tool call error can cause the model's output quality to completely collapse70% similarUnverified代理化场景对模型的工具调用和长程规划能力要求更高，而这些维度是传统代码生成基准难以充分衡量的69% similar
