What problem does it solve? Training data often lags behind real library releases, so API signatures, configuration options, and migration details recalled from memory are frequently outdated or wrong. This Skill queries live documentation through the Context7 CLI so answers about any library, framework, SDK, or CLI tool reflect current versions. ## Core Features & Use Cases - Library Resolution: Converts a package or product name into a Context7-compatible library ID (format /org/project), ranked by name similarity, snippet count, source reputation, and benchmark score. - Documentation Querying: Fetches up-to-date code snippets and prose explanations for a resolved library ID, including version-specific IDs like /vercel/next.js/v14.3.0-canary.87. - Use Case: When asked how to clean up an async useEffect in React, resolve the library with ctx7 library react "..." and then pull current docs with ctx7 docs /facebook/react "..." instead of relying on potentially stale training knowledge. ## Quick Start Ask the assistant to look up the current documentation for a specific library question, such as how to configure authentication middleware in the latest Next.js app router.
