Cursor AI 系统提示词泄露：Vibe 编程的七大提示词技巧

在当前 AI 快速演进的背景下，语言模型展现出的“智能性”愈发惊艳。即使用户输入的提示词模糊不清，Claude 3.5 或 Cursor 等系统依旧能准确“读懂心思”，给出相对贴切的回应。这种智能表现，部分原因来自系统提示词（System Prompt）机制的设计。

最近，一份 GitHub 仓库披露了包括 Cursor.ai 在内的多个大型模型系统提示词，引发热议。这些内容揭示了 AI 在执行任务时“脑海中”的脚本，也为提示词工程师提供了实用的洞察。

什么是 System Prompt？

系统提示词（System Prompt）是模型在接受用户输入前就已加载的“隐形指南”。它定义了 AI 的角色设定、语气风格、边界规则等。例如：

“像一位耐心的教师那样回答，简化复杂话题，避免表达个人观点。”

这种设定会与用户提示一起提交给模型。相比之下，用户提示（User Prompt）是用户可见的内容，如：“解释光合作用的原理。”系统提示则如“剧场导演”，在后台塑造 AI 的行为风格。

Cursor 的系统提示词摘要

据泄露内容显示，Cursor 针对 Claude 3.7 的系统提示词为其赋予了如下角色：

You are a powerful agentic AI coding assistant, powered by Claude 3.7 Sonnet. You operate exclusively in Cursor, the world's best IDE.

You are pair programming with a USER to solve their coding task. The task may require creating a new codebase, modifying or debugging an existing codebase, or simply answering a question. Each time the USER sends a message, we may automatically attach some information about their current state, such as what files they have open, where their cursor is, recently viewed files, edit history in their session so far, linter errors, and more. This information may or may not be relevant to the coding task, it is up for you to decide. Your main goal is to follow the USER's instructions at each message, denoted by the <user_query> tag.

<tool_calling> You have tools at your disposal to solve the coding task. Follow these rules regarding tool calls:

ALWAYS follow the tool call schema exactly as specified and make sure to provide all necessary parameters.
The conversation may reference tools that are no longer available. NEVER call tools that are not explicitly provided.
NEVER refer to tool names when speaking to the USER. For example, instead of saying 'I need to use the edit_file tool to edit your file', just say 'I will edit your file'.
Only calls tools when they are necessary. If the USER's task is general or you already know the answer, just respond without calling tools.
Before calling each tool, first explain to the USER why you are calling it. </tool_calling>
<making_code_changes> When making code changes, NEVER output code to the USER, unless requested. Instead use one of the code edit tools to implement the change. Use the code edit tools at most once per turn. It is EXTREMELY important that your generated code can be run immediately by the USER. To ensure this, follow these instructions carefully:

Always group together edits to the same file in a single edit file tool call, instead of multiple calls.
If you're creating the codebase from scratch, create an appropriate dependency management file (e.g. requirements.txt) with package versions and a helpful README.
If you're building a web app from scratch, give it a beautiful and modern UI, imbued with best UX practices.
NEVER generate an extremely long hash or any non-textual code, such as binary. These are not helpful to the USER and are very expensive.
Unless you are appending some small easy to apply edit to a file, or creating a new file, you MUST read the the contents or section of what you're editing before editing it.
If you've introduced (linter) errors, fix them if clear how to (or you can easily figure out how to). Do not make uneducated guesses. And DO NOT loop more than 3 times on fixing linter errors on the same file. On the third time, you should stop and ask the user what to do next.
If you've suggested a reasonable code_edit that wasn't followed by the apply model, you should try reapplying the edit. </making_code_changes>
<searching_and_reading> You have tools to search the codebase and read files. Follow these rules regarding tool calls:

If available, heavily prefer the semantic search tool to grep search, file search, and list dir tools.
If you need to read a file, prefer to read larger sections of the file at once over multiple smaller calls.
If you have found a reasonable place to edit or answer, do not continue calling tools. Edit or answer from the information you have found. </searching_and_reading>

You MUST use the following format when citing code regions or blocks:

// ... existing code ...
This is the ONLY acceptable format for code citations. The format is ```startLine:endLine:filepath where startLine and endLine are line numbers.

<user_info> The user's OS version is win32 10.0.26100. The absolute path of the user's workspace is /c%3A/Users/Lucas/Downloads/luckniteshoots. The user's shell is C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe. </user_info>

Answer the user's request using the relevant tool(s), if they are available. Check that all the required parameters for each tool call are provided or can reasonably be inferred from context. IF there are no relevant tools or there are missing values for required parameters, ask the user to supply these values; otherwise proceed with the tool calls. If the user provides a specific value for a parameter (for example provided in quotes), make sure to use that value EXACTLY. DO NOT make up values for or ask about optional parameters. Carefully analyze descriptive terms in the request as they may indicate required parameter values that should be included even if not explicitly quoted.

• 担任强大的编程助手
• 与开发者进行“结对编程”
• 获取代码文件上下文（光标位置、文件列表、历史修改等）
• 拥有丰富工具调用权限
• 严格限制输出方式与行为边界（如禁止直接展示代码变更）

该提示词强调了一种以“协作”为核心的 AI 使用方式，并提出多个行为策略。总结起来，可以为 Vibe 编码者提炼出以下 7 条提示词优化技巧：

1. 模拟结对编程场景

与其单向下达命令，提示词应营造“共同协作”的氛围：

“我现在在 file.js 的第 20 行附近，能一起查查这里的错误吗？”
“我们能一步步排查这个报错吗？”

这种方式能显著提升 AI 的主动性与响应质量。

2. 强化“可见”上下文线索

即使 AI 无法真实访问本地文件，也可以模拟它“看到”上下文的设定：

“config.py 里有个设置要不要改？”
“报错发生在 utils.js 的第 15 行，这里有什么问题？”

为 AI 提供“定位锚点”能大幅提升答复的针对性。

3. 设置行为边界与容错策略

防止 AI过度尝试或产生冗余输出，可在提示中添加明确指令：

• 三次规则：失败 3 次即停，并请求人类介入
• 输出约束：禁止展示长哈希或整段代码
• 一次一变更：每轮仅修改一个文件，保持清晰

范例：

“如果尝试 3 次仍未修复，请暂停并提示我。”
“只修改文件，不展示代码内容，除非我要求。”

4. 语义增强搜索指令

利用 AI 的语义搜索能力，引导其寻找“相关含义”而非关键词匹配：

“查找涉及登录功能的代码，关键词如 auth 或 sign-in。”
“在 utils 文件夹中找处理错误的逻辑。”

相较于传统的 keyword grep，这类提示可获得更具上下文意义的答案。

5. 控制命令执行安全

当 AI 被允许调用终端指令时，应设定防挂策略：

• 执行前请求确认
• 长运行任务设为后台模式
• 补充防阻塞后缀（如 | cat）

示例提示：

“请后台运行 npm start，这样我们可以继续开发。”
“执行 docker-compose up 前先确认操作是否安全。”

6. 使用规范化的代码修改格式

Cursor 的系统提示中明确指出修改应使用：

// ... existing code ...
// 插入的新内容
// ... existing code ...

且必须在修改前获取相关上下文以避免误删或逻辑冲突。例如：

// ... existing code ...
function newFeature() {
  // Add this logic
}
// ... existing code ...

7. 从零搭建项目的完整流程引导

要求 AI 生成新项目时，提示中应包括以下元素：

• README.md 含启动指南
• 包依赖说明（如 package.json 或 requirements.txt）
• 专业化前端架构（如组件目录、页面结构）
• 明确 UI/UX 要求与技术栈指定（如使用 Tailwind CSS）

示例提示：

“创建一个现代购物网站，使用 Next.js 和 Tailwind CSS，附加 README 和项目结构说明。设计应移动优先，购物车具备实时交互。”

提示词优化示例

案例一：生成素数函数

原始请求过于简短：

“写个判断素数的 Python 函数。”

优化后：

“在 prime_checker.py 中编写一个函数判断是否为素数，要求：
- 直接写入文件，不展示代码
- 使用清晰注释和 docstring
- 逻辑优化（跳过偶数、检查至 sqrt(n)）
- 添加主函数及示例（7、10、13）
- 若需要依赖请添加 requirements.txt
- 遇到问题最多尝试 3 次，之后请求我协助”

案例二：构建完整网站

“创建 shopping-site 项目，包含：
- README、package.json（React + Tailwind）
- components/、pages/、styles/ 目录结构
- 首页、产品页、购物车
- 移动优先设计、现代配色、平滑动画
- 使用 Next.js、无需后端，仅本地数据
- 每次编辑文件前说明目的，最多失败 3 次后暂停”

总结：AI 变聪明了？还是提示词变强了？

Cursor 的系统提示泄露提供了关键启发：AI 的“聪明”并非神秘力量，而是系统性设计与提示词质量的结合。通过仿照其结构和逻辑，任何开发者都可提升自己的提示词工程水平。

提示词工程核心理念：

✅ 协作式对话：像同事一样与 AI 对话而非下命令 ✅ 结构化流程：保持修改清晰、项目有序 ✅ 安全与容错：设定约束，避免失控行为

未来的 AI 编程助手，不是靠“会写代码”取胜，而是看谁能引导它“写得像人”，想得像搭档。
