使用 Node.js 脚本实现 Claude Code 技能与 GitHub Copilot 的映射复用

这段配置定义了"去哪找"（sourceDir）、'找什么'（sourcePattern）以及"怎么展示"（groupBy）。特别是 frontmatterFields，它直接从 Markdown 的头部元数据（Frontmatter）中提取技能描述，这是 Copilot 理解技能用途的关键。

2. 智能提取与分组

脚本不仅是简单的列表生成，还包含了智能的分类逻辑。例如，getSkillCategory 函数维护了一个映射表，将杂乱的技能归类为 'Content & Writing'、'Development'、'Project Management' 等类别。

// 示例：将技能映射到类别
const categories = {
  "tech-blog": "Content & Writing",
  "code-review": "Code Analysis",
  zustand: "Development",
  // ...
};

这种结构化的输出对于 LLM（大语言模型）非常友好。当 Copilot 阅读这份文档时，它能建立起结构化的认知：'哦，如果用户要写文章，我应该去 Content & Writing 分类下找找。'

3. 生成 Copilot 可读的指令

仅仅列出文件是不够的，我们还需要告诉 Copilot 如何使用 这些技能。脚本会读取 templates 目录下的指令模版，并将其嵌入到生成的 Markdown 头部。

以 skills-mapping.md 为例，生成的头部包含这样的指令：

'当用户激活本地技能时… 1. 识别技能引用… 3. 使用 Read 工具读取 SKILL.md 文件… 4. 将技能规则应用到当前会话…'

这相当于给 Copilot 植入了一段"元指令"（Meta-Prompt），教它如何加载和执行外部技能。

4. 完整实现

2. Agent Template 格式

## Agent 使用流程
当用户输入命令时，按以下步骤执行：
1. **解析命令快捷方式**
   - 顶层命令：直接查找表格（格式：`/command`）
   - 嵌套命令：解析 category:command 格式（格式：`/category:command`）
2. **查找映射表**
   - 在对应分类表格中查找快捷方式列
   - 获取完整路径字段
3. **读取命令文件**
   - 使用 Read 工具读取完整路径对应的 .md 文件
   - 解析 frontmatter 获取 allowed-tools 和其他元数据
4. **执行命令**
   - 按照命令文件中的指令执行
   - 严格使用 frontmatter 中指定的 allowed-tools
   - 如果未指定 allowed-tools，使用默认工具集

实战演练：在 Copilot 中调用 tech-blog

万事俱备，现在的核心问题是：体验如何？

假设你已经运行了脚本，生成了 skills-mapping.md。

1. 加载上下文：在 VSCode Copilot Chat 中，通过 @workspace 或直接打开 skills-mapping.md 文件，让 Copilot 读取这个文件。
2. 下达指令：输入 '我想写一篇关于 Zustand 状态管理的博客，使用 tech-blog 技能的深度风格。'
3. Copilot 的思考链：
   • 扫描 skills-mapping.md。
   • 发现 tech-blog 条目，描述匹配 '技术博客文章创作工具'。
   • 获取路径 ~/.claude/skills/tech-blog/SKILL.md。
   • (关键一步) Copilot 会读取该路径下的文件内容（前提是你允许它读取，或者你将内容复制到了 Context 中）。
   • Copilot 学习到 tech-blog 的 Prompt 规则（如 3W 框架、金句要求）。
   • 执行输出：Copilot 按照 tech-blog 的深度版风格，生成了一篇结构完美的文章。

这通过一次简单的映射，打破了工具间的壁垒。 你在 Claude Code 里沉淀的每一次 Prompt 优化、每一个 Agent 调教，现在都能无缝同步给编辑器里的 Copilot。

总结

'工欲善其事，必先利器'。但在 AI 时代，我们面临的问题往往不是器不够利，而是"器"太多且互不相通。

通过 scan-and-generate.mjs 这样一个小巧的胶水脚本，我们不仅仅是生成了一份文档，更是建立了一座桥梁。它连接了 CLI 的灵活性与 IDE 的便捷性，连接了系统级的能力与编辑器级的交互。

现在，去运行你的扫描脚本，把你的 Claude Code 变成 Copilot 的最强外脑吧。
