Why use this instead of a standard MCP client?

Standard clients return full, unfiltered documentation that consumes massive amounts of context; this skill reduces that footprint by over 77% per request.

Which libraries are supported?

It supports a wide range of popular frameworks including React, Next.js, Prisma, Express, NestJS, Vue, Fastify, and many others available via Context7.

Can I use this for conceptual learning?

Yes, the skill features an '--mode info' flag specifically designed to return conceptual explanations and architectural patterns rather than just code.

How does this skill save tokens?

It uses a shell pipeline involving awk, grep, and sed to filter raw documentation within a subprocess, ensuring only essential code and API data are sent to the LLM.

学習とドキュメンテーション

Fetches library documentation and code examples with 77% token efficiency using intelligent shell-based filtering.

概要

This skill optimizes how Claude retrieves technical documentation from the Context7 MCP by utilizing a specialized shell pipeline to filter raw API responses. By extracting only essential code examples, API signatures, and key notes while discarding unnecessary metadata in a subprocess, it achieves a massive reduction in token usage. This allows developers to maintain a larger project context while still accessing comprehensive documentation for frameworks like React, Next.js, Prisma, and Express.
