Installation

1. Add the marketplace to Claude Code

Open Claude Code and run /plugins, then select Add Marketplace and enter:

lorismaz/rails-claude-code-plugins

2. Enable plugins

After adding the marketplace, select the plugins you want to enable from the list. Or add them manually to your settings (~/.claude/settings.json for global, .claude/settings.json for per-project):

{
  "enabledPlugins": {
    "ruby-lsp@rails-claude-code-plugins": true,
    "herb-lsp@rails-claude-code-plugins": true,
    "rubocop-lsp@rails-claude-code-plugins": true,
    "stimulus-lsp@rails-claude-code-plugins": true,
    "solargraph@rails-claude-code-plugins": true,
    "charm-ruby@rails-claude-code-plugins": true,
    "reactive-rails-ui@rails-claude-code-plugins": true
  }

LSP Servers

Five language server integrations that give Claude Code full code intelligence for Ruby and Rails projects.

Plugin	Install prerequisite	File types
ruby-lsp	gem install ruby-lsp	.rb, .rbw, .rake, .gemspec
herb-lsp	npm i -g @herb-tools/language-server	.erb
rubocop-lsp	gem install rubocop	.rb
stimulus-lsp	npm i -g stimulus-language-server	.html, .erb
solargraph	gem install solargraph	.rb, .rake, .gemspec

What You Get

• Go to Definition — jump to where a method, class, or variable is defined
• Find References — find all usages of a symbol across your codebase
• Hover — see documentation, type info, and method signatures
• Diagnostics — real-time linting errors and warnings
• Document Symbols — list all classes, methods, and constants in a file
• Workspace Symbols — search for symbols across your entire project

Choosing Between ruby-lsp, solargraph, and rubocop-lsp

• ruby-lsp — Shopify's modern Ruby LSP. Best all-around choice for navigation and diagnostics.
• solargraph — Excellent for documentation lookup and type inference via YARD annotations.
• rubocop-lsp — Focused on linting. Use alongside ruby-lsp or solargraph for style enforcement.

A good default setup for Rails projects:

{
  "enabledPlugins": {
    "ruby-lsp@rails-claude-code-plugins": true,
    "herb-lsp@rails-claude-code-plugins": true,
    "stimulus-lsp@rails-claude-code-plugins": true
  }
}

Charm Ruby — CLI Tooling

Build beautiful, interactive command-line applications in Ruby using the charm-ruby ecosystem (Bubble Tea, Lipgloss, Bubbles, Huh, and more).

Skill

The charm-ruby-development skill activates when you ask about building CLI tools in Ruby. It provides comprehensive knowledge of the Bubble Tea MVU architecture, Lipgloss styling, component integration, and gem distribution.

Commands

Command	Description
/charm:new-cli [name]	Scaffold a new charm-ruby CLI project
/charm:add-component [type]	Add a Bubbles component to your project
/charm:package	Prepare your CLI for RubyGems distribution

Agent: CLI Architect

Expert Ruby CLI architect that helps you design application architecture, plan multi-screen navigation, and select appropriate components.

Reactive Rails UI

Build smooth, reactive Rails UIs using three techniques that make standard redirect-based controllers feel as responsive as a SPA — with zero client-side state management:

1. Turbo Morphing — diffs the DOM instead of replacing it, preserving scroll position and focus
2. View Transitions API — browser-native crossfade animations between page states
3. Stimulus Optimistic UI — instant visual feedback via aria-attribute toggling before the server responds
