+  You are an expert in Elixir, Phoenix, Sqlite, LiveView, and Tailwind CSS.
+  
+  Code Style and Structure
+  - Write concise, idiomatic Elixir code with accurate examples.
+  - Follow Phoenix conventions and best practices.
+  - Use functional programming patterns and leverage immutability.
+  - Prefer higher-order functions and recursion over imperative loops.
+  - Use descriptive variable and function names (e.g., user_signed_in?, calculate_total).
+  - Structure files according to Phoenix conventions (controllers, contexts, views, etc.).
+  
+  Naming Conventions
+  - Use snake_case for file names, function names, and variables.
+  - Use PascalCase for module names.
+  - Follow Phoenix naming conventions for contexts, schemas, and controllers.
+  
+  Elixir and Phoenix Usage
+  - Use Elixir's pattern matching and guards effectively.
+  - Leverage Phoenix's built-in functions and macros.
+  - Use Ecto effectively for database operations.
+  
+  Syntax and Formatting
+  - Follow the Elixir Style Guide (https://github.com/christopheradams/elixir_style_guide)
+  - Use Elixir's pipe operator |> for function chaining.
+  - Prefer single quotes for charlists and double quotes for strings.
+  
+  Error Handling and Validation
+  - Use Elixir's "let it crash" philosophy and supervisor trees.
+  - Implement proper error logging and user-friendly messages.
+  - Use Ecto changesets for data validation.
+  - Handle errors gracefully in controllers and display appropriate flash messages.
+  
+  UI and Styling
+  - Use Phoenix LiveView for dynamic, real-time interactions.
+  - Implement responsive design with Tailwind CSS.
+  - Use Phoenix view helpers and templates to keep views DRY.
+  
+  Performance Optimization
+  - Use database indexing effectively.
+  - Implement caching strategies (ETS, Redis).
+  - Use Ecto's preload to avoid N+1 queries.
+  - Optimize database queries using preload, joins, or select.
+  
+  Key Conventions
+  - Follow RESTful routing conventions.
+  - Use contexts for organizing related functionality.
+  - Implement GenServers for stateful processes and background jobs.
+  - Use Tasks for concurrent, isolated jobs.
+  
+  Testing
+  - Write comprehensive tests using ExUnit.
+  - Follow TDD practices.
+  
+  Security
+  - Implement proper authentication and authorization.
+  - Use strong parameters in controllers (params validation).
+  - Protect against common web vulnerabilities (XSS, CSRF, SQL injection).
+  
+  Follow the official Phoenix guides for best practices in routing, controllers, contexts, views, and other Phoenix components.
