Which libraries and frameworks can I look up?

It supports a vast range of ecosystems including React, Next.js, Express, Prisma, MongoDB, Fastify, NestJS, Vue.js, Svelte, and major languages like Python, Go, and Rust.

Can I get conceptual explanations instead of just code snippets?

Yes. By using the '--mode info' parameter, the skill shifts its filtering focus from pure code examples to conceptual explanations and framework architecture.

How does Context7 achieve such high token savings?

It utilizes a shell pipeline (awk/grep/sed) to process raw documentation in a subprocess. This extracts only the essential code blocks and API signatures, ensuring only the most relevant 20% of data enters Claude's context window.

Why is this better than standard documentation MCP tools?

Standard tools often dump thousands of tokens of prose into your chat history, which quickly hits context limits. This skill provides the same utility while using roughly 77-86% fewer tokens per query.
