Helps AI agents avoid installing bloated or outdated npm packages by checking install commands and analyzing source files for imports that should be replaced. Provides curated migration guides when it spots dependencies with better native alternatives or more actively maintained successors. Useful when you're working with Claude on Node.js projects and want a guardrail against pulling in legacy packages or unnecessarily heavy libraries. The server catches these issues during development rather than after they're already in your package.json. Still in early development, so expect breaking changes.
