// what's inside
What's inside this skill
- Idiomatic Ruby methods and classes with the matching RSpec or Minitest spec
- Refactors using guard clauses, Enumerable and pattern matching, RuboCop-clean
- Code reviews ranked must fix, should fix, nit with code suggestions
- Stack trace diagnosis, benchmark-ips harnesses and gem or Rake task scaffolds
Backend and Rails developers, scripters and gem authors who write Ruby every day.
What you're actually buying
This Claude/ChatGPT skill gives you a Ruby AI pair programmer that writes and reviews the code you work on every day: idiomatic methods and classes with keyword arguments and pattern matching, refactors that replace nested ifs and each loops with guard clauses and Enumerable calls, RSpec or Minitest specs for the class you paste, fixes for NoMethodError on nil and Bundler errors, and benchmark-ips harnesses when a loop is slow.
It knows the Ruby standard library, blocks vs procs vs lambdas, frozen string literals, the GVL and Fibers, bundler and rbenv workflows, RuboCop and Standard conventions, and the gem ecosystem from Rails and Sidekiq to Nokogiri and Faraday. It is a language helper, not a job-role persona. It does not run your code or commands; it writes the code, the spec and the shell command, and you run them.
Works the same way in Claude, ChatGPT and Gemini. One purchase, download the file, install in under 2 minutes, then paste your Ruby the way you would show it to a senior colleague.
# AI Skill for Ruby KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then just ask questions the way you normally would. ## Who you are You are a senior Ruby developer acting as the user's pair programmer: you know Ruby idioms, the standard library, the gem ecosystem, the tooling and the performance traps, and you review code the way a careful colleague would. You are not a job-role persona; you sit next to the user inside their editor and terminal. You optimise for readable, idiomatic Ruby that is tested and easy to change. Tone: direct, practical, code first, explanation second. ## What you know about Ruby - Language core: everything is an object, blocks, procs and lambdas (and how they differ on return and arity), symbols vs strings, frozen string literals, keyword ar

Questions about this product
What does the AI Skill for Ruby do?+
It turns Claude or ChatGPT into a Ruby AI pair programmer that writes idiomatic Ruby, refactors your existing methods, writes RSpec or Minitest tests, reviews classes and diffs, explains stack traces, scaffolds gems, Rake tasks and Thor CLIs, and builds benchmark harnesses for slow code. You paste Ruby, it returns better Ruby with the reasoning.
Does it run my Ruby code for me?+
No. It does not execute Ruby, run bundle exec rspec or touch your repository. It writes the code, the spec and the exact shell command, and you run them in your terminal. Anything that touches production data or files comes with a dry-run or transaction warning first.
Does it follow RuboCop and my Ruby version?+
Yes. Tell it your Ruby version (ruby -v) and whether you use RuboCop or Standard, and it writes code that matches the available syntax (pattern matching, endless methods, Data) and the linter defaults. If it is not sure a method exists in your Ruby version, it says so and points you to ri or the docs.
Is this the same as a Ruby on Rails role skill?+
No. This is a Ruby language helper: idioms, stdlib, gems, testing and tooling for any Ruby code, Rails or not. A role skill plays a full developer persona for project-level decisions. Use this one when you want a pair programmer for the Ruby in front of you.
Which AI tools does this skill work with?+
Works with Claude (recommended), Claude Code, ChatGPT, Gemini and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results because it remembers your Ruby version, test framework and RuboCop conventions between chats.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
