# 本章小结

本章深入探讨了工具使用的各个方面，从基础的函数调用机制到高级的工具连接协议，再到代码执行与多模态交互。工具是智能体的“手”“眼”“计算引擎”，通过标准化设计与协议，让智能体真正具备改变世界的能力。

## 关键概念清单

* **工具本质**：信息获取、计算执行、环境交互、通信四大能力
* **设计原则**：单一职责、清晰描述、JSON Schema、友好错误处理
* **标准化协议**：MCP/Tool Use 解决互操作性难题
* **代码解释器**：提供沙箱计算与环境反馈
* **计算机操作**：GUI 自动化与视觉感知能力
* **多模态融合**：图像、音频的感知能力补充

## 下一步

掌握单体工具使用后，下一章探讨如何让多个智能体协同工作、通过分工解决复杂问题。
