# Ralph Development Instructions

## Context
You are Ralph, an autonomous AI development agent working on a Task Management App project.

## Current Objectives
1. Study specs/* to learn about the project specifications
2. Review fix_plan.md for current priorities
3. Implement the highest priority item using best practices
4. Use parallel subagents for complex tasks (max 100 concurrent)
5. Run tests after each implementation
6. Update documentation and fix_plan.md

## Key Principles
- ONE task per loop - focus on the most important thing
- Search the codebase before assuming something isn't implemented
- Use subagents for expensive operations (file searching, analysis)
- Write comprehensive tests with clear documentation
- Update fix_plan.md with your learnings
- Commit working changes with descriptive messages

## Testing Guidelines (CRITICAL)
- LIMIT testing to ~20% of your total effort per loop
- PRIORITIZE: Implementation > Documentation > Tests
- Only write tests for NEW functionality you implement
- Do NOT refactor existing tests unless broken
- Focus on CORE functionality first, comprehensive testing later

## Project Requirements
- User authentication and authorization
- Task CRUD operations
- Team collaboration features
- Real-time updates

## Technical Constraints
- Frontend: React.js with TypeScript
- Backend: Node.js with Express
- Database: PostgreSQL

## Success Criteria
- Users can create and manage tasks efficiently
- Team collaboration features work seamlessly
- App loads quickly (<2s initial load)

## Current Task
Follow fix_plan.md and choose the most important item to implement next.

# Ralph Fix Plan

## High Priority
- [ ] Set up user authentication with JWT
- [ ] Implement task CRUD API endpoints
- [ ] Create task list UI component

## Medium Priority
- [ ] Add team/workspace management
- [ ] Implement task assignment features
- [ ] Add due date and reminder functionality

## Low Priority
- [ ] Real-time updates with WebSocket
- [ ] Task comments and attachments
- [ ] Mobile PWA support

## Completed
- [x] Project initialization

## Notes
- Focus on MVP functionality first
- Ensure each feature is properly tested
- Update this file after each major milestone
EOF

# Create specs/requirements.md in .ralph/specs/
cat > .ralph/specs/requirements.md << 'EOF'
# Technical Specifications

## System Architecture
- Frontend: React.js SPA with TypeScript
- Backend: Node.js REST API with Express
- Database: PostgreSQL with Prisma ORM
- Authentication: JWT with refresh tokens

## Data Models

### User
- id: UUID
- email: string (unique)
- password_hash: string
- name: string
- avatar_url: string (optional)
- created_at: timestamp

### Task
- id: UUID
- title: string
- description: text (optional)
- priority: enum (high, medium, low)
- due_date: timestamp (optional)
- completed: boolean
- user_id: UUID (foreign key)
- created_at: timestamp

## API Specifications

### Authentication
- POST /api/auth/register - User registration
- POST /api/auth/login - User login
- POST /api/auth/refresh - Refresh token
- POST /api/auth/logout - User logout

### Tasks
- GET /api/tasks - List user's tasks
- POST /api/tasks - Create task
- GET /api/tasks/:id - Get task details
- PUT /api/tasks/:id - Update task
- DELETE /api/tasks/:id - Delete task

## Performance Requirements
- Initial page load: <2 seconds
- API response time: <200ms
- Support 100 concurrent users

## Security Considerations
- Password hashing with bcrypt
- HTTPS required in production
- Rate limiting on auth endpoints
- Input validation on all endpoints
