Is this skill useful for Rails development?

Definitely. It points to high-level engineering resources like Shopify's Rails at Scale blog, which covers the latest updates in Ruby and its surrounding tooling.

Why does this skill avoid ruby-doc.org and apidock?

This skill prioritizes the official docs.ruby-lang.org to ensure the AI uses the most accurate, version-specific, and up-to-date information, as community mirrors are often outdated.

Does it support the latest Ruby versions?

Yes, the skill includes authoritative resource mapping for Ruby 3.2, 3.3, 3.4, 4.0, and the master branch.

How does it handle Ruby typing systems?

It provides a comprehensive map for both the RBS (official Ruby) and RBI (Sorbet) ecosystems, including tools like Tapioca, Spoom, and Steep.
