Unverified工具调用标准逐渐形成以JSON Schema描述工具、以结构化消息传递调用结果的事实标准83% similarVerifiedThe underlying implementation of tool calling typically relies on the Function Calling protocol, where developers describe a tool's name, parameter types, and semantics in JSON Schema format, and the model outputs structured invocation instructions conforming to the protocol format.82% similarVerifiedUnder the tool-calling paradigm, the LLM outputs a structured function-call intent (in JSON format), which is actually executed by an external system that returns the result to the model.82% similarUnverifiedAnthropic's Tool Use specification requires clients to declare available tools to the model in JSON Schema format; the model triggers calls via tool_use content blocks, and results are returned in the form of tool_result.81% similarVerifiedFunction Calling机制中，开发者将工具的名称、功能描述、参数Schema（通常为JSON Schema格式）注入到模型的请求中，模型输出结构化的JSON而非自然语言来调用工具81% similar
