Just give the answer. +- Follow the user's requirements carefully & to the letter. +- First think step-by-step - describe your plan for what to build in pseudocode, written out in great detail. +- Confirm, then write code! +- Always write correct, up to date, bug free, fully functional and working, secure, performant and efficient code. +- Focus on readability over being performant. +- Fully implement all requested functionality. - Leave NO todo's, placeholders or missing pieces. - Be sure to reference file names. - Be concise. Minimize any other prose. - If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing. + +Code Style and Structure +- Write concise, idiomatic Ruby code with accurate examples. +- Follow Rails conventions and best practices. +- Use object-oriented and functional programming patterns as appropriate. +- Prefer iteration and modularization over code duplication. +- Use descriptive variable and method names (e.g., user_signed_in?, calculate_total). +- Structure files according to Rails conventions (MVC, concerns, helpers, etc.). + +Naming Conventions +- Use snake_case for file names, method names, and variables. +- Use CamelCase for class and module names. +- Follow Rails naming conventions for models, controllers, and views. + +Ruby and Rails Usage +- Use Ruby 3.x features when appropriate (e.g., pattern matching, endless methods). +- Leverage Rails' built-in helpers and methods. +- Use ActiveRecord effectively for database operations. + +Syntax and Formatting +- Follow the Ruby Style Guide (https://rubystyle.guide/) +- Use Ruby's expressive syntax (e.g., unless, ||=, &.) +- Prefer single quotes for strings unless interpolation is needed. + +Error Handling and Validation +- Use exceptions for exceptional cases, not for control flow. +- Implement proper error logging and user-friendly messages. +- Use ActiveModel validations in models. +- Handle errors gracefully in controllers and display appropriate flash messages. + +UI and Styling +- Use Hotwire (Turbo and Stimulus) for dynamic, SPA-like interactions. +- Implement responsive design with Tailwind CSS. +- Use Rails view helpers and partials to keep views DRY. + +Performance Optimization +- Use database indexing effectively. +- Implement caching strategies (fragment caching, Russian Doll caching). +- Use eager loading to avoid N+1 queries. +- Optimize database queries using includes, joins, or select. + +Key Conventions +- Follow RESTful routing conventions. +- Use concerns for shared behavior across models or controllers. +- Implement service objects for complex business logic. +- Use background jobs (e.g., Sidekiq) for time-consuming tasks. + +Testing +- Write comprehensive tests using RSpec or Minitest. +- Follow TDD/BDD practices. +- Use factories (FactoryBot) for test data generation. + +Security +- Implement proper authentication and authorization (e.g., Devise, Pundit). +- Use strong parameters in controllers. +- Protect against common web vulnerabilities (XSS, CSRF, SQL injection). + +Follow the official Ruby on Rails guides for best practices in routing, controllers, models, views, and other Rails components.
