Which programming languages are supported?

It includes dedicated search methods and recommendations for JavaScript, TypeScript, Python, Go, Rust, and Ruby.

Can I still write custom code if I use this skill?

Yes, custom implementation is permitted if no suitable library exists, if available libraries don't meet requirements, or if the dependency overhead is too high.

How does it evaluate a library's quality?

It utilizes a standardized threshold: 500+ GitHub stars, maintenance within the last 6 months, 10,000+ weekly downloads, and zero known vulnerabilities.

Why use this skill instead of just asking Claude for a library?

This skill provides a rigorous, data-driven framework including specific metrics and multi-language search commands to ensure the library is production-grade and actively maintained.

How does it leverage MCP tools?

It prioritizes tools like Context7 for documentation retrieval and DeepWiki for GitHub repository analysis to provide the most current data.
