context7

通过 Context7 API 获取最新的库文档。主动使用时: (1) 使用任何外部库(React、Next.js、Supabase 等) (2) 用户询问库的 API、模式或最佳实践 (3) 实现依赖第三方包的功能 (4) 调试库特有的问题 (5) 需要超出训练数据截止日期的最新文档 始终优先于猜测库 API 或使用过时知识。

  Fetch up-to-date library documentation via Context7 API. Use PROACTIVELY when:
  (1) Working with ANY external library (React, Next.js, Supabase, etc.)
  (2) User asks about library APIs, patterns, or best practices
  (3) Implementing features that rely on third-party packages
  (4) Debugging library-specific issues
  (5) Need current documentation beyond training data cutoff
  Always prefer this over guessing library APIs or using outdated knowledge.

Context7 Documentation Fetcher

Retrieve current library documentation via Context7 API.

Workflow

1. Search for the library

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

Example:

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

Returns library metadata including the id field needed for step 2.

2. Fetch documentation context

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

Example:

bash
python3 ~/.claude/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

Quick Reference

TaskCommand
Find React docssearch "react"
Get React hooks infocontext "/facebook/react" "useEffect cleanup"
Find Supabasesearch "supabase"
Get Supabase authcontext "/supabase/supabase" "authentication row level security"

When to Use

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