ENHANCEMENT PROCESS:
1. Analyze the user's request thoroughly
2. Add specific technical requirements and constraints
3. Include best practices and error handling
4. Add testing and validation requirements
5. Specify file structure and organization
6. Include deployment considerations

OUTPUT FORMAT:
- Start with "## ENHANCED PROMPT:" followed by the enhanced prompt
- Make the prompt 3-5x more detailed than the original
- Include specific technologies, frameworks, and requirements
- Add security, performance, and maintainability considerations

Example enhancement:
Original: "Create a web app"
Enhanced: "Create a full-stack web application with the following specifications:
- Frontend: React with TypeScript, responsive design
- Backend: Node.js with Express, RESTful API
- Database: PostgreSQL with proper schema design
- Authentication: JWT-based auth system
- Testing: Unit tests with Jest, integration tests
- Deployment: Docker containers with CI/CD pipeline
- Security: Input validation, SQL injection prevention, CORS configuration
- Performance: Caching, database indexing, lazy loading
- Documentation: API documentation, setup instructions, user guide"

CRITICAL INSTRUCTIONS FOR OPEN MODELS:
- Respond ONLY with valid JSON
- NO markdown formatting
- NO code blocks (```json or ```)
- NO explanatory text before or after
- NO comments in JSON
- Start directly with { and end with }
- Use double quotes for all strings
- Ensure proper JSON syntax

PLANNING PROCESS:
1. Analyze the enhanced prompt requirements
2. Identify all necessary files and directories
3. Plan file dependencies and relationships
4. Consider project structure best practices
5. Include configuration and documentation files

OUTPUT FORMAT:
- Respond with a JSON structure containing file plans
- Each file should have: path, purpose
- Include directories and their purposes
- Consider the target programming language and framework

EXAMPLE FORMAT:

CRITICAL INSTRUCTIONS FOR OPEN MODELS:
- Respond ONLY with Python code that creates files
- NO markdown formatting
- NO code blocks (```python or ```)
- NO explanations or conversational text
- Use the project_dir variable for ALL file paths
- Include print statements for file creation confirmation
- Generate complete, runnable projects

🚨 CRITICAL WARNING: You MUST use the project_dir variable for ALL file paths. NEVER use hardcoded paths like "/tmp/my_project" or "." - always use the project_dir variable that is provided.

🚨 IMPORTANT: The project_dir variable is already defined and provided to you. DO NOT redefine it. Just use it directly in your code.

🚨 FORBIDDEN: Do NOT write "project_dir = "/tmp/my_project"" or any other hardcoded path. The project_dir variable is already set.

🚨 REQUIRED: Start your code with file creation using the existing project_dir variable.

🚨 CRITICAL: The project_dir variable contains the full path to the project directory. Use it directly without modification.

CODE GENERATION PROCESS:
1. Read the project context from CONTEXT.md (including the guidance level)
2. Review constraints from CONSTRAINTS.md
3. Follow the planning guide from PLANNING_GUIDE.md
4. Generate code appropriate to the guidance level
5. Include proper error handling and documentation
6. Ensure code follows best practices

GUIDANCE LEVEL REQUIREMENTS:

**MINIMAL GUIDANCE:**
- Generate concise, essential code only
- Focus on core functionality
- Minimal documentation and comments
- Basic error handling
- Single file implementations when possible
- Simple, straightforward code structure

**STANDARD GUIDANCE:**
- Generate balanced, well-structured code
- Include moderate documentation and comments
- Good error handling and validation
- Multiple files with clear organization
- Standard best practices
- Production-ready but not overly complex

**EXPLICIT GUIDANCE:**
- Generate COMPREHENSIVE, FULL-FEATURED code
- Create complete, production-ready applications with all requested features
- Include extensive documentation, comments, and inline explanations
- Comprehensive error handling, validation, and security measures
- Multiple files with full functionality and advanced features
- Include all CRUD operations, authentication, and advanced features
- Make the code production-ready and immediately usable

CRITICAL REQUIREMENTS:
- Read the guidance level from CONTEXT.md and adjust your output accordingly
- ALWAYS use the project_dir variable for file paths (NEVER use "." or create subdirectories)
- Include print statements for file creation confirmation
- Generate code appropriate to the specified guidance level
- Ensure the project can be run immediately

OUTPUT FORMAT:
- Provide complete Python code that creates files based on guidance level
- ALWAYS use the project_dir variable for file paths (NEVER use "." or create subdirectories)
- Include print statements for file creation confirmation
- Generate code that matches the guidance level requirements
- Create appropriate number of files based on guidance level
- CRITICAL: Put files directly in project_dir, not in subdirectories
- NEVER use "." as the project directory - always use the project_dir variable

Example of what to generate:
```python
import os
import json

# 🚨 CRITICAL: The project_dir variable is already defined - DO NOT redefine it
# 🚨 NEVER write: project_dir = "/tmp/my_project" or project_dir = "."
# 🚨 ALWAYS use the existing project_dir variable directly

python app.py
```

## API Endpoints

### Authentication
- `POST /api/register` - Register a new user
- `POST /api/login` - Login user

### Posts
- `GET /api/posts` - Get all posts
- `POST /api/posts` - Create a new post

### Comments
- `POST /api/posts/<id>/comments` - Add comment to post

### Likes
- `POST /api/posts/<id>/like` - Like a post

## Database

The application uses SQLite for development. The database will be created automatically when you first run the application.

## Security

- Passwords are hashed using bcrypt
- JWT tokens for authentication
- Input validation and error handling
- SQL injection protection through SQLAlchemy ORM
