# 第十二章 提示词工程进阶与上下文工程

> 从“会提问”到“会引导”，从优化一句话到优化整个知识背景

***

掌握了基础提示词技巧后，本章将带你进入两个更深层的领域：

**提示词进阶**：如何引导 AI 进行深度思考，用思维链、结构化输出和迭代优化解决复杂任务。

**上下文工程**：提示词只是 AI 看到的“一句话”，上下文工程则优化 AI 看到的“整个背景”——包括 RAG、知识库和 MCP 协议。这是 2026 年 AI 应用的核心能力。

## 本章内容

**Part A：提示词进阶**

* [**12.1 思维链**](/ai_beginner_guide/di-san-bu-fen-shi-zhan-ying-yong-ji-qiao/12_prompt_advanced/12.1_chain_of_thought.md)：让 AI 学会“慢思考”，展示推理步骤
* [**12.2 结构化输出**](/ai_beginner_guide/di-san-bu-fen-shi-zhan-ying-yong-ji-qiao/12_prompt_advanced/12.2_structured_output.md)：让 AI 直接输出表格或数据，而非写作文
* [**12.3 迭代优化**](/ai_beginner_guide/di-san-bu-fen-shi-zhan-ying-yong-ji-qiao/12_prompt_advanced/12.3_iterative.md)：好的提示词不是一次写成的，而是“试”出来的
* [**12.4 高级技巧**](/ai_beginner_guide/di-san-bu-fen-shi-zhan-ying-yong-ji-qiao/12_prompt_advanced/12.4_advanced_techniques.md)：自洽性、角色反转、强化约束等“黑科技”

**Part B：上下文工程**

* [**12.5 上下文工程**](/ai_beginner_guide/di-san-bu-fen-shi-zhan-ying-yong-ji-qiao/12_prompt_advanced/12.5_context_engineering.md)：从提示词到知识库，理解 RAG 与 MCP 协议
