docs

为各类库和框架获取最新文档。关键——自动调用： - 当用户希望使用任何外部库（如 GSAP、Lenis、Three.js、Framer、Radix 等）进行开发时； - 当用户询问“如何使用 X”、“X 的文档”、“X 的 API”、“X 的参考信息”时； - 在编写任何依赖外部包的代码之前； - 当用户提及库名：gsap、lenis、three、framer、motion、radix、sanity、zustand。务必牢记：切勿自以为熟知 API。每次使用前，务必先获取最新文档。

name: docs description: | Fetch latest documentation for libraries and frameworks. CRITICAL - AUTO-INVOKE when: - User wants to implement with ANY external library (GSAP, Lenis, Three.js, Framer, Radix, etc.) - User asks "how to use X", "X docs", "X API", "X reference" - Before writing ANY code that uses external packages - User mentions library names: gsap, lenis, three, framer, motion, radix, sanity, zustand MANDATORY: Never assume API knowledge. Always fetch current docs first. context: fork allowed-tools: [mcp__context7__resolve-library-id, mcp__context7__get-library-docs, WebFetch, WebSearch]

CRITICAL: Always fetch current documentation before implementing with ANY external library. APIs change. Your training data is outdated.

Using Context7 MCP

bash

# Step 1: Resolve library ID
mcp__context7__resolve-library-id { "libraryName": "gsap" }

# Step 2: Fetch docs for specific topic
mcp__context7__get-library-docs {
  "context7CompatibleLibraryID": "greensock/docs",
  "topic": "ScrollTrigger",
  "tokens": 10000
}

Common Libraries

Library	Context7 ID	Topics
GSAP	`greensock/docs`	ScrollTrigger, Timeline, Tweens
Lenis	`darkroom/lenis`	setup, scrollTo, events
Three.js	`mrdoob/three.js`	Scene, Camera, Renderer
Framer Motion	`framer/motion`	animate, variants, gestures
Radix	`radix-ui/primitives`	Dialog, Dropdown, Tabs
Next.js	`vercel/nextjs`	App Router, Server Components
React	`facebook/react`	hooks, components, patterns
Sanity	`sanity-io/sanity`	GROQ, schemas, studio

Pre-Implementation Checklist

Before writing code with a library:

•Fetch docs - Get current API documentation
•Check version - Run bun info <package>
•Find examples - Look for usage patterns in docs
•Verify imports - Confirm correct import paths

Output

After fetching docs, summarize:

•Key APIs needed for the task
•Import statements to use
•Example usage from docs
•Gotchas or important notes

Remember

•NEVER write library code from memory
•Always verify current API before implementing
•Store useful discoveries as learnings
