- Write concise, idiomatic Ruby code with accurate examples
- Follow Rails conventions and best practices
- Use descriptive variable and method names (e.g., user_signed_in?, calculate_total)
- Structure files according to Rails conventions (MVC, concerns, helpers)

Naming Conventions:
- Use snake_case for file names, method names, and variables
- Use CamelCase for class and module names

- Implement caching strategies (fragment caching, Russian Doll caching)
- Use eager loading to avoid N+1 queries

Security:
- Implement proper authentication (rails g authentication)
- Use strong parameters in controllers
