Ruby Skills: Teaching Claude Code About Ruby's Tooling And Ecosystem - st0012.dev

Eventually you add something like Use chruby 4.0.0 to run Ruby commands in either the project or your user-level CLAUDE.md. While this is frustrating, I don’t blame Claude. Ruby has at least seven version managers - rbenv, chruby, rvm, asdf, mise, rv, shadowenv - and Claude doesn’t know which one you’re using. This is an example of a bigger question: how can a community teach AI to handle its ecosystem’s quirks? Or how does it know about areas that are still rapidly developing, like the typing and tooling scene in Ruby? So I built ruby-skills to solve the version manager problem and experiment with community-maintained guardrails for Claude Code.
