Superpowers (Ruby/Rails Edition)

A Ruby on Rails–focused fork of obra/superpowers — a complete software development workflow for coding agents built on composable "skills".

Ruby/Rails Focus

This fork extends the core superpowers workflow with a full Ruby on Rails skills library:

• Ruby language idioms, modern features (3.x+), OOD philosophy
• Rails testing with Minitest and fixtures (no RSpec, no Capybara, no system tests)
• Brakeman security scanning
• Sandi Metz rules for maintainable OOP
• Official Rails guides indexed for quick reference
• 37signals/Basecamp patterns derived from Fizzy codebase analysis
• Hotwire (Turbo + Stimulus) skills from Hotwire Club
• Commit messages following Conventional Commits with Ruby-specific body guidance

All examples, test commands, and file references use Ruby/Rails conventions throughout.

Superpowers is a complete software development workflow for your coding agents, built on top of a set of composable "skills" and some initial instructions that make sure your agent uses them.

Here are the sources that I used to get the skills that are embeded here:

• https://github.com/el-feo/ai-context
• https://github.com/nateberkopec/dotfiles
• https://github.com/marckohlbrugge/unofficial-37signals-coding-style-guide
• https://github.com/rails/rails/tree/main/guides
• https://github.com/TheHotwireClub/hotwire_club-skills

How it works

It starts from the moment you fire up your coding agent. As soon as it sees that you're building something, it doesn't just jump into trying to write code. Instead, it steps back and asks you what you're really trying to do.

Once it's teased a spec out of the conversation, it shows it to you in chunks short enough to actually read and digest.

After you've signed off on the design, your agent puts together an implementation plan that's clear enough for an enthusiastic junior engineer with poor taste, no judgement, no project context, and an aversion to testing to follow. It emphasizes true red/green TDD, YAGNI (You Aren't Gonna Need It), and DRY.

Next up, once you say "go", it launches a subagent-driven-development process, having agents work through each engineering task, inspecting and reviewing their work, and continuing forward. It's not uncommon for Claude to be able to work autonomously for a couple hours at a time without deviating from the plan you put together.

There's a bunch more to it, but that's the core of the system. And because the skills trigger automatically, you don't need to do anything special. Your coding agent just has Superpowers.

Sponsorship

If Superpowers has helped you do stuff that makes money and you are so inclined, I'd greatly appreciate it if you'd consider sponsoring my Jesse's opensource work.

Thanks!

Installation

Note: Installation differs by platform. Claude Code or Cursor have built-in plugin marketplaces. Codex and OpenCode require manual setup.

Claude Code — Option 1: Install from GitHub

Register the marketplace, then install the plugin:

/plugin marketplace add lucianghinda/superpowers-ruby
/plugin install superpowers-ruby@superpowers-ruby

Claude Code — Option 2: Install from local clone

Clone the repository and install from the local directory:

git clone https://github.com/lucianghinda/superpowers-ruby.git
/plugin install ./superpowers-ruby

Cursor

Until the plugin is published on the cursor marketplace, use this command :

cd ~/.cursor/plugins/local/ && git clone https://github.com/lucianghinda/superpowers-ruby

Codex

Tell Codex:

Fetch and follow instructions from https://raw.githubusercontent.com/lucianghinda/superpowers-ruby/refs/heads/main/.codex/INSTALL.md

Detailed docs: docs/README.codex.md

OpenCode

Tell OpenCode:

Fetch and follow instructions from https://raw.githubusercontent.com/lucianghinda/superpowers-ruby/refs/heads/main/.opencode/INSTALL.md

Detailed docs: docs/README.opencode.md

GitHub Copilot CLI

copilot plugin marketplace add lucianghinda/superpowers-ruby
copilot plugin install superpowers-ruby@superpowers-ruby

Gemini CLI

gemini extensions install https://github.com/lucianghinda/superpowers-ruby

To update:

gemini extensions update superpowers-ruby

Verify Installation

Start a new session in your chosen platform and ask for something that should trigger a skill (for example, "help me plan this feature" or "let's debug this issue"). The agent should automatically invoke the relevant superpowers skill.
