SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @upstash/context7-mcp, and includes scripts (resource) and references (resource) components.

What problem does it solve? Fetching library documentation through MCP normally dumps large raw responses into the AI context, consuming hundreds of tokens per query. This Skill filters documentation through shell pipelines so only code examples, API signatures, and key notes reach the model, cutting token usage by roughly 77%. ## Core Features & Use Cases - Token-Efficient Fetching: Wraps Context7 MCP calls in a shell pipeline that extracts code blocks, API signatures, and important notes using awk, grep, and sed. - Library Resolution: Resolves library names like React, Next.js, or Prisma to Context7-compatible IDs, or accepts direct IDs for faster lookups. - Flexible Modes and Pagination: Supports code mode for examples, info mode for conceptual explanations, and pagination across up to 10 pages. - Use Case: When a user asks "Show me React useState examples", the Skill fetches the full documentation in a subprocess and returns only about 205 filtered tokens of examples and signatures instead of the full 934-token response. ## Quick Start Ask the assistant to fetch documentation for a library and topic, for example: "Show me React hooks examples using the context7-efficient skill."

FAQPage Schema
How do I fetch library documentation with Context7 MCP?

Run the fetch-docs.sh script with a library name and topic, such as --library react --topic hooks. The script resolves the library ID, fetches documentation via the Context7 MCP server, and returns filtered code examples and API signatures.

How does this skill reduce token usage for documentation lookups?

It keeps the full MCP response inside a shell subprocess and filters it with awk, grep, and sed before returning results. Only extracted code blocks, signatures, and notes enter the model context, reducing usage from about 934 tokens to roughly 205 tokens per query.

Which libraries are supported by Context7 documentation fetching?

Any library indexed by Context7 works, including React, Next.js, Express, Prisma, MongoDB, Vue, Svelte, Fastify, and NestJS. You can pass a library name for automatic resolution or a direct Context7 ID like /vercel/next.js for faster lookups.

What is the difference between code mode and info mode?

Code mode returns up to five code examples plus API signatures, which suits syntax and usage lookups. Info mode returns fewer examples alongside conceptual overview paragraphs, which suits learning a new framework or understanding architecture.

Why does library resolution fail for some package names?

Resolution fails when the name does not match Context7's indexed titles. Try name variations such as next.js, nextjs, or next, or pass the exact Context7-compatible ID directly with --library-id to skip resolution entirely.
