CONTEXT: I'm building a Ruby on Rails application with Hotwire for real-time features
ACTION: Generate a complete user authentication system
FORMAT: Provide code files with explanations, following Rails conventions

Additional specifications:
- Use Devise gem
- Include Hotwire Turbo integration
- Add password strength validation
- Include email confirmation
- Provide migration files
- Add proper test coverage

I'm designing a social media application with these requirements:
- 10,000+ concurrent users
- Real-time messaging
- Content recommendation engine
- Multi-platform support (web, iOS, Android)

Please help me:
1. Choose the optimal tech stack
2. Design the database schema
3. Plan the microservices architecture
4. Identify potential bottlenecks
5. Suggest caching strategies

Consider using Ruby on Rails with Hotwire for the main application.

Design a PostgreSQL database schema for an e-learning platform with:
- Users (students, instructors, admins)
- Courses with multiple lessons
- Progress tracking
- Quizzes and assessments
- Certificates

Provide:
- Complete Rails migrations
- Model associations
- Database indexes for performance
- Sample seed data

# Prompt for generating a complete feature
prompt = """
Create a complete Ruby on Rails feature for course enrollment with:

1. Models: User, Course, Enrollment
2. Controller with actions: index, show, create, destroy
3. Views with Hotwire Turbo integration
4. Real-time enrollment notifications
5. Enrollment capacity limits
6. Payment integration placeholder
7. Email notifications
8. Comprehensive RSpec tests

Include proper error handling and validation.
"""

Generate a complete REST API for a task management system using Rails:

Resources needed:
- Projects (name, description, status)
- Tasks (title, description, due_date, completed, priority)
- Users (name, email, role)

Include:
- JWT authentication
- Proper serializers
- API versioning (v1)
- Rate limiting
- Comprehensive documentation
- Error handling
- Test coverage

Follow JSON:API standards.

Generate comprehensive RSpec tests for this Rails model:

class Task < ApplicationRecord
  belongs_to :project
  belongs_to :assignee, class_name: 'User'

  validates :title, presence: true, length: { minimum: 3 }
  validates :priority, inclusion: { in: %w[low medium high urgent] }
  validates :due_date, presence: true

  scope :completed, -> { where(completed: true) }
  scope :pending, -> { where(completed: false) }
  scope :overdue, -> { where('due_date < ? AND completed = ?', Time.current, false) }

  def mark_completed!
    update!(completed: true, completed_at: Time.current)
  end
end

Include tests for:
- Validations
- Associations
- Scopes
- Methods
- Edge cases

I need to implement a real-time collaborative text editor in Rails with Hotwire. 

Break this down into steps:
1. Initial analysis and approach
2. Database design for operational transforms
3. WebSocket integration with Action Cable
4. Conflict resolution algorithms
5. Frontend implementation with Stimulus
6. Performance optimization
7. Testing strategies

For each step, provide detailed implementation code and explanations.

I'm new to Ruby on Rails and want to understand Hotwire Turbo Streams deeply.

Provide a comprehensive learning path:
1. Fundamental concepts with simple examples
2. Real-world use cases and implementations
3. Advanced patterns and best practices
4. Common pitfalls and how to avoid them
5. Performance considerations
6. Testing approaches
7. Integration with other technologies

Include practical exercises I can implement.

- Using PostgreSQL
- Deploying to Heroku
- Migration files exist

Help me:
1. Diagnose the root cause
2. Provide step-by-step troubleshooting
3. Suggest prevention strategies
4. Recommend debugging tools

My Rails application is slow. Here's my performance data:
- Average response time: 800ms
- Database queries: 15+ per request
- Memory usage: 200MB+ per process

Controllers involved:
[Include controller code]

Models involved:
[Include model code]

Help me:
1. Identify performance bottlenecks
2. Optimize database queries
3. Implement caching strategies
4. Reduce memory usage
5. Improve overall response times
