# 第四章 工具使用与环境交互

工具是智能体的“手”“眼”与“计算引擎”。本章从工具设计原则出发，讲解函数调用 → 标准化协议(MCP) → 代码执行 → 计算机操作 → 多模态融合的完整路径。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。

## 学习目标

完成本章后，你将能够：

1. **理解** 工具使用的核心机制与设计原则
2. **实现** 基于Tool Use的工具集成与标准化协议
3. **搭建** 安全的代码执行与计算机操作环境
4. **集成** 多模态感知能力

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://yeasy.gitbook.io/agentic_ai_guide/di-yi-bu-fen-dan-ti-zhi-neng-jia-gou/04_tools.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
