Context7

Pulls fresh documentation from the Context7 API when you're working with external libraries beyond Claude's training cutoff. You search for a library by name, get its ID, then query specific documentation with configurable token limits. Output comes in text or markdown. The workflow is straightforward: run a Python script to search, another to fetch docs. Requires an API key stored in a .env file in the skill directory. Most useful when you're installing new dependencies, debugging library-specific issues, or need to verify current API details rather than relying on potentially outdated training data. It's a practical bridge between Claude's knowledge and whatever's actually published right now.
