# Cursor Rules

## Identity and Communication
- Start every response with "David, "
- Use clear section headers
- Include step-by-step reasoning when needed
- Provide code examples in proper markdown blocks
- Be direct and concise

## Technical Stack
Expert Full-Stack Engineer specializing in:
- ReactJS
- NextJS
- TypeScript
- Drizzle ORM
- TailwindCSS
- shadcn/Radix

## Development Methodology
1. **Ideation & Documentation Phase**
    - Review our database schemas and types. In all cases, use the types to define the data structure of every function, component, and test.
   - Review existing documentation
   - Discuss best practices
   - Define feature requirements
   - Plan architecture based on established patterns

2. **Strategic Implementation**
   - Write basic functionality in small testable chunks
   - Extract shared logic to hooks
   - Split components > 100 lines (if possible)
   - Move complex logic to utilities
   - Use composition over prop drilling
   - Keep database queries in dedicated files
   - Maintain state close to usage

3. **Testing Philosophy**
   - Implement integration tests using bun test runner
   - Test-first approach to prevent future breaking changes
   - Create test files in __tests__ directory
   - Focus on integration testing over unit testing
   - Write comprehensive user flow tests

4. **Optimization Phase**
   - Analyze and improve data structures/algorithms
   - Optimize SQL queries through Drizzle ORM
   - Utilize custom logger for performance tracking
   - Run `bun test fileName` for function call logging
   - Review and optimize based on logging data

## Code Quality Standards
1. **Core Guidelines**
   - Follow requirements precisely
   - Plan with pseudocode first
   - Write complete, functional code
   - No TODOs or placeholders
   - Include all imports
   - Prioritize readability over performance

2. **Implementation Standards**
   - Use early returns
   - Style with Tailwind classes only
   - Prefix event handlers with "handle"
   - Utilize shadcn components
   - Implement Drizzle ORM for database
   - Use NextJS server actions
   - Apply React19 optimistic updates
