Context7 Documentation Fetcher

Context7 文档获取工具

Retrieve current library documentation via Context7 API.

通过Context7 API获取最新的库文档。

Authentication

认证

This skill requires a Context7 API key in

CONTEXT7_API_KEY

Recommended setup options:

Export it in your shell profile (global):

bash

export CONTEXT7_API_KEY="your-context7-key"

Use a local
```
.env
```
file (per-repo):

bash

cp skills/context7/.env.example .env
set -a; source .env; set +a

此技能需要在

CONTEXT7_API_KEY

中配置Context7 API密钥。

推荐的设置选项：

在shell配置文件中全局导出：

bash

export CONTEXT7_API_KEY="your-context7-key"

使用本地
```
.env
```
文件（按仓库配置）：

bash

cp skills/context7/.env.example .env
set -a; source .env; set +a

Workflow

工作流程

1. Search for the library

1. 搜索库

bash

python3 ~/.codex/skills/context7/scripts/context7.py search "<library-name>"

Example:

bash

python3 ~/.codex/skills/context7/scripts/context7.py search "next.js"

Returns library metadata including the

id

field needed for step 2.

bash

python3 ~/.codex/skills/context7/scripts/context7.py search "<library-name>"

示例：

bash

python3 ~/.codex/skills/context7/scripts/context7.py search "next.js"

返回库的元数据，包括步骤2所需的

id

字段。

2. Fetch documentation context

2. 获取文档上下文

bash

python3 ~/.codex/skills/context7/scripts/context7.py context "<library-id>" "<query>"

Example:

bash

python3 ~/.codex/skills/context7/scripts/context7.py context "/vercel/next.js" "app router middleware"

Options:

```
--type txt|md
```
- Output format (default: txt)
```
--tokens N
```
- Limit response tokens

bash

python3 ~/.codex/skills/context7/scripts/context7.py context "<library-id>" "<query>"

示例：

bash

python3 ~/.codex/skills/context7/scripts/context7.py context "/vercel/next.js" "app router middleware"

选项：

```
--type txt|md
```
- 输出格式（默认：txt）
```
--tokens N
```
- 限制响应的token数量

When to Use

使用场景

Before implementing any library-dependent feature
When unsure about current API signatures
For library version-specific behavior
To verify best practices and patterns

在实现任何依赖库的功能之前
不确定当前API签名时
需要了解库特定版本的行为时
验证最佳实践和模式时
