Decision brief
What it does—and where it fits
创建 CodeTour .tour 文件,用于代码库导览,可直接打开真实文件并定位到指定行范围。导览文件存放在 .tours/ 目录中,专为 CodeTour 格式设计,而非临时性的 Markdown 笔记。
Not for
- Tasks that require unconfirmed production actions or broad system permissions.
- Environments where the pinned source and install steps cannot be inspected.

代码导览
创建 CodeTour .tour 文件,用于代码库导览,可直接打开真实文件并定位到指定行范围。导览文件存放在 .tours/ 目录中,专为 CodeTour 格式设计,而非临时性的 Markdown 笔记。
一个好的导览应针对特定读者讲述一个故事:
- 他们正在查看什么
- 为什么重要
- 接下来应该遵循什么路径
仅创建 .tour JSON 文件。不要在此技能范围内修改源代码。
何时使用
在以下情况下使用此技能:
- 用户请求代码导览、入职导览、架构导览或 PR 导览
- 用户说“解释 X 如何工作”,并希望获得可重用的引导式产物
- 用户希望为新工程师或审阅者提供上手路径
- 相比平铺直叙的摘要,引导式序列更适合该任务
示例:
- 新维护者入职
- 单个服务或包的架构导览
- 锚定到变更文件的 PR 审查导览
- 展示故障路径的根本原因分析导览
- 信任边界和关键检查的安全审查导览
何时不使用
| 不使用代码导览的情况 | 使用 |
|---|---|
| 在聊天中一次性解释就足够了 | 直接回答 |
用户想要散文式文档,而不是 .tour 产物 | documentation-lookup 或仓库文档编辑 |
| 任务是实现或重构 | 执行实现工作 |
| 任务是没有导览产物的广泛代码库入职 | codebase-onboarding |
工作流程
1. 探索
在编写任何内容之前探索仓库:
- README 和包/应用入口点
- 文件夹结构
- 相关配置文件
- 如果导览聚焦于 PR,则查看变更的文件
在理解代码结构之前,不要开始编写步骤。
2. 推断读者
根据请求确定角色和深度。
| 请求形式 | 角色 | 建议深度 |
|---|---|---|
| "入职","新成员" | new-joiner | 9-13 步 |
| "快速导览","快速了解" | vibecoder | 5-8 步 |
| "架构" | architect | 14-18 步 |
| "导览此 PR" | pr-reviewer | 7-11 步 |
| "为什么这个出错了" | rca-investigator | 7-11 步 |
| "安全审查" | security-reviewer | 7-11 步 |
| "解释此功能如何工作" | feature-explainer | 7-11 步 |
| "调试此路径" | bug-fixer | 7-11 步 |
3. 读取并验证锚点
每个文件路径和行锚点必须是真实的:
- 确认文件存在
- 确认行号在范围内
- 如果使用选区,验证确切的代码块
- 如果文件易变,优先使用基于模式的锚点
切勿猜测行号。
4. 编写 .tour
写入:
.tours/<persona>-<focus>.tour
保持路径确定且可读。
5. 验证
在完成之前:
- 每个引用的路径都存在
- 每行或每个选区都有效
- 第一步锚定到真实文件或目录
- 导览讲述连贯的故事,而非罗列文件
步骤类型
内容
谨慎使用,通常仅用于结束步骤:
{ "title": "Next Steps", "description": "You can now trace the request path end to end." }
不要将第一步设为纯内容。
目录
用于引导读者了解模块:
{ "directory": "src/services", "title": "Service Layer", "description": "The core orchestration logic lives here." }
文件 + 行
这是默认步骤类型:
{ "file": "src/auth/middleware.ts", "line": 42, "title": "Auth Gate", "description": "Every protected request passes here first." }
选区
当某个代码块比整个文件更重要时使用:
{
"file": "src/core/pipeline.ts",
"selection": {
"start": { "line": 15, "character": 0 },
"end": { "line": 34, "character": 0 }
},
"title": "Request Pipeline",
"description": "This block wires validation, auth, and downstream execution."
}
模式
当精确行号可能发生变化时使用:
{ "file": "src/app.ts", "pattern": "export default class App", "title": "Application Entry" }
URI
在需要时用于 PR、问题或文档:
{ "uri": "https://github.com/org/repo/pull/456", "title": "The PR" }
编写规则:SMIG
每个描述应回答:
- 情境:读者正在查看什么
- 机制:它是如何工作的
- 影响:为什么对此角色重要
- 陷阱:聪明的读者可能会错过什么
保持描述简洁、具体,并基于实际代码。
叙事结构
除非任务明确需要不同结构,否则使用此弧线:
- 定位
- 模块地图
- 核心执行路径
- 边缘情况或陷阱
- 结束 / 下一步
导览应感觉像一条路径,而非清单。
示例
{
"$schema": "https://aka.ms/codetour-schema",
"title": "API Service Tour",
"description": "Walkthrough of the request path for the payments service.",
"ref": "main",
"steps": [
{
"directory": "src",
"title": "Source Root",
"description": "All runtime code for the service starts here."
},
{
"file": "src/server.ts",
"line": 12,
"title": "Entry Point",
"description": "The server boots here and wires middleware before any route is reached."
},
{
"file": "src/routes/payments.ts",
"line": 8,
"title": "Payment Routes",
"description": "Every payments request enters through this router before hitting service logic."
},
{
"title": "Next Steps",
"description": "You can now follow any payment request end to end with the main anchors in place."
}
]
}
反模式
| 反模式 | 修复 |
|---|---|
| 平铺直叙的文件列表 | 讲述一个步骤间有依赖关系的故事 |
| 通用描述 | 指明具体的代码路径或模式 |
| 猜测的锚点 | 先验证每个文件和行 |
| 快速导览步骤过多 | 果断精简 |
| 第一步是纯内容 | 将第一步锚定到真实文件或目录 |
| 角色不匹配 | 为实际读者编写,而非通用工程师 |
最佳实践
- 步骤数量与仓库大小和角色深度成比例
- 使用目录步骤进行定位,文件步骤用于实质内容
- 对于 PR 导览,首先覆盖变更的文件
- 对于单体仓库,将范围限定在相关包,而非导览所有内容
- 以读者现在可以做什么来结束,而非总结
