# Context7 Documentation Skill (CLI)
## 自动触发
检测到以下情况时自动激活:
- 使用外部库/框架 (React, Next.js, Vue, Express...)
- 查看 package.json / go.mod / requirements.txt 中的依赖
- 报错涉及第三方 API
## 使用方式
```bash
# 搜索库
npx ctx7 search "react hooks"
# 获取文档
npx ctx7 docs react --topic="useState"
# 指定版本
npx ctx7 docs next@14 --topic="app router"
```
## 与 mcp-deepwiki 分工
| 工具 | 负责 | 示例 |
|:---|:---|:---|
| context7 | 库/框架级 API 文档 | React hooks 用法 |
| mcp-deepwiki | 架构/Wiki 级知识 | 系统设计模式 |
## 降级
context7 CLI 不可用 → mcp-deepwiki 搜索 → Web 搜索。
