AI-generated answers based on this skill's SKILL.md and metadata
How do I use lookup to find current API documentation?
lookup retrieves up-to-date library documentation, API references, and code examples through either a CLI tool or MCP server interface. Use lookup whenever you need to verify current API syntax, configuration, setup steps, or version-specific guidance for any library, framework, SDK, or cloud service instead of relying on potentially stale training data.
Can lookup help me verify syntax and configuration before using a library?
Yes. lookup is designed to verify syntax, configuration, or setup instructions for a library before using it. You can look up current best practices and exact API signatures to ensure your code will work correctly with the specific version you're targeting.
How do I look up React useEffect cleanup and other framework documentation?
lookup retrieves documentation for popular frameworks like React. Simply query lookup with your question—for example, 'lookup react useEffect cleanup'—and it will return current API documentation, code examples, and best practices for that specific feature or method.
Does lookup support version-specific guidance when migrating libraries?
Yes. lookup helps you find version-specific guidance and breaking changes when migrating between library versions. You can search for migration guides, deprecation notices, and compatibility information to plan upgrades safely.
What libraries and services does lookup cover?
lookup covers a wide range of libraries, frameworks, SDKs, and cloud services—including React, Node.js, Express, TypeScript, Python packages, Django, AWS, Next.js, Mongoose, FastAPI, Webpack, GraphQL, Tailwind CSS, GitHub API, Prisma, Docker, and many others. If it has public documentation, lookup can retrieve it.
How do I set up the lookup CLI tool and authentication?
lookup can be installed and configured as a CLI tool or MCP server. For setup details specific to your platform—such as installing on Windows—refer to the Context7 documentation or use lookup's own setup guidance to configure authentication and begin retrieving documentation.
