UnverifiedThe 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.80% similarUnverifiedThe underlying mechanism of the Skill system is the large model's Function Calling capability, where developers describe tools in JSON Schema format, and the model determines whether to invoke them and outputs structured call instructions77% similarUnverifiedSkill 在底层实现上本质是将结构化指令注入到模型的上下文窗口中，类似于定制化的 System Prompt，但具备更好的模块化和复用性77% similar
