Ruby On Rails Development

Rails Development Router

Welcome! I'll help route your Rails development task to the appropriate specialist.

🎯 How This Works

Based on your request, I'll automatically activate the right specialist skill:

🚀 Quick Start

Just describe what you want to build:

✅ "Create User model with email validation"
✅ "Add authentication with Devise"
✅ "Build a dashboard component"
✅ "Setup CI/CD pipeline"
✅ "Optimize slow queries"

I'll analyze your request and activate the right specialist!

📚 Core Rails Principles

All specialists follow these NON-NEGOTIABLE principles:

1. Test-First Development (TDD)

Every feature MUST follow Red-Green-Refactor:

# 1. RED - Write failing test FIRST
RSpec.describe User do
  it "validates email presence" do
    user = User.new(email: nil)
    expect(user).not_to be_valid
  end
end

# 2. Run test - MUST fail
# 3. GREEN - Write minimal code to pass
# 4. REFACTOR - Improve while tests pass

Rules:

• ✅ Tests written BEFORE implementation
• ✅ Never commit failing tests
• ✅ Never skip/disable tests to pass builds
• ✅ Red-Green-Refactor cycle strictly enforced

2. YAGNI Principle

You Aren't Gonna Need It - Don't create abstractions until needed.

# ❌ Don't create prematurely
# app/services/      (until pattern emerges)
# app/presenters/    (use decorators instead)
# config/constants.rb (for values used once)

# ✅ Create when actually needed
# app/interactions/  (ActiveInteraction)
# app/components/    (ViewComponents)

3. Convention Over Configuration

Follow Rails conventions unless compelling reason:

• Naming: Models singular, Controllers plural
• Routes: RESTful design
• Structure: Standard Rails directories
• Patterns: Rails way first

4. Security by Design

Always:

• ✅ Strong parameters in controllers
• ✅ Authorization on all actions (Pundit)
• ✅ Encrypt sensitive data (Lockbox)
• ✅ HTTPS in production
• ✅ Rate limiting on APIs

5. Incremental Progress

Each commit should:

• ✅ Compile successfully
• ✅ Pass all tests
• ✅ Be deployable
• ✅ Represent complete feature slice

💡 Example Workflows

Simple Task (One Specialist)

YOU: "Add email validation to User model"

CLAUDE: [Activates rails-testing]
        Writing test first (TDD)...
        Test fails (RED) ✓
        Adding validation...
        Test passes (GREEN) ✓

Complex Task (Multiple Specialists)

YOU: "Build comment system for articles"

CLAUDE: [Activates rails-project-manager]
        Analyzing requirements...

        Plan:
        Stage 1: Model & Tests (rails-testing)
        Stage 2: Business Logic (rails-business-logic)
        Stage 3: API (rails-api)
        Stage 4: UI Components (rails-viewcomponents)
