UnverifiedDuring multi-turn tool calls, each tool execution result is appended to the conversation history as a new tool_result message, and the model reads the outputs of previous steps from the conversation context rather than retaining intermediate values in internal memory.79% similarUnverifiedTool-use patterns are a memory type unique to multi-turn agent systems, referring to tool invocation methods that were verified as effective in previous sessions.77% similarUnverifiedInline tool definitions re-declare tools via a system message, with the effect of overriding or extending the set of tools currently available to the model.76% similarUnverifiedTool calling refers to the mechanism by which an Agent requests the execution of an external function through a structured message and has the result returned; the returned content enters the conversation history as a message with role: 'tool' and from then on permanently occupies the context.75% similarUnverified自定义工具（Custom Tool）可以将重复流程封装起来实现一键复用，绕过重复推理72% similar
