Context7

This pulls current library docs through Context7's API so Claude stops hallucinating outdated React hooks or nonexistent Next.js patterns. You search for a library, get its ID, then query for specific documentation like "useEffect cleanup" or "middleware authentication." It's most useful when you're working with fast-moving frameworks where the training data is likely stale, or when you explicitly need version-specific examples. The workflow is straightforward: two API calls and you get code snippets with source URLs. Honest take: it's solving a real problem with LLM staleness, though you're adding API latency to every coding question that triggers it.
