VerifiedThe tool-calling (Function Calling / Tool Use) capability enables LLMs to output structured intent instructions, which are captured by an external execution layer to actually operate on systems.76% similarUnverified在LangChain、AutoGen、Semantic Kernel等主流Agent框架中，Skill或Tool被定义为封装特定功能的可调用单元，包含输入输出规范、功能描述和执行逻辑三要素75% similarUnverifiedClaude's tool calling follows the standard function signature format defined by Anthropic; developers declare available tools via JSON Schema, and the model independently decides whether to call a tool and what parameters to pass.73% similarUnverifiedThe key breakthrough in tool-calling capability lies in the model's ability to generate structured function-call requests and correctly parse tool return results before continuing to reason, rather than simply concatenating tool outputs into the prompt72% similarUnverified工具Schema包含功能说明、参数名称、类型、含义解释以及required标记参数是否必填72% similar
