Context7 Documentation Fetcher

Context7 文档获取工具

This skill fetches up-to-date documentation and code examples from libraries using the Context7 API.

此技能通过Context7 API获取各库的最新文档和代码示例。

Standard Workflow

标准工作流程

Context7 requires a two-step process:

Context7需要遵循两步流程：

Step 1: Search for the Library ID

步骤1：搜索库ID

First, search for the library to get its ID:

GET https://context7.com/api/v2/libs/search?libraryName=<library>&query=<context>

Parameters:

```
libraryName
```
: The library name (e.g., "react", "nextjs", "fastapi")
```
query
```
: Search context to help find the right library

The response contains a

results

array with library objects. Use the

id

field from the first result.

首先搜索对应库以获取其ID：

GET https://context7.com/api/v2/libs/search?libraryName=<library>&query=<context>

参数：

```
libraryName
```
：库的名称（例如："react"、"nextjs"、"fastapi"）
```
query
```
：帮助定位对应库的搜索上下文

返回结果中包含

results

数组，数组元素为库对象，使用第一个结果中的

id

字段即可。

Step 2: Get Documentation Context

步骤2：获取文档上下文

Use the library ID to fetch relevant documentation:

GET https://context7.com/api/v2/context?libraryId=<id>&query=<question>

Parameters:

```
libraryId
```
: The ID from step 1 (e.g., "/vercel/next.js")
```
query
```
: Natural language question about the documentation

This returns ranked code snippets and documentation matching your query.

使用库ID来获取相关文档：

GET https://context7.com/api/v2/context?libraryId=<id>&query=<question>

参数：

```
libraryId
```
：步骤1中获取的ID（例如："/vercel/next.js"）
```
query
```
：关于文档的自然语言问题

该接口会返回与你的查询匹配的、已排序的代码片段和文档内容。

Example Usage

示例用法

When the user asks about a library:

Search for the library: Fetch
```
https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing
```
Extract the library ID from the response (e.g., "/vercel/next.js")

Fetch documentation: Fetch

https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=How to setup dynamic routes

Present the results to the user with the relevant code examples and documentation.

当用户询问某个库的相关问题时：

搜索对应库：请求
```
https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing
```
从返回结果中提取库ID（例如："/vercel/next.js"）

获取文档：请求

https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=How to setup dynamic routes

向用户展示结果，包含相关的代码示例和文档内容。

Tips for Best Results

最佳实践提示

Use specific, detailed queries rather than vague terms
Include relevant context in the query (e.g., "useState hook with TypeScript" instead of just "state")
The API works without an API key but has restricted rate limits

使用具体、详细的查询词，不要使用模糊表述
在查询中包含相关上下文（例如："useState hook with TypeScript"而非仅"state"）
该API无需API密钥即可使用，但有速率限制约束
