 ## 🤖 Agent Guidelines
 ### Before Making Changes
 1. **Understand the Context**
   - Read relevant documentation in `docs/`
   - Check `TODO.md` for current priorities
   - Review `SECURITY_AUDIT.md` for security considerations
   - Check `ROADMAP.md` for feature direction
 2. **Check Existing Patterns**
   - Look at similar existing code first
   - Follow the established patterns in the codebase
   - Don't introduce new patterns without good reason
 3. **Identify Dependencies**
   - Check if your change affects multiple modules
   - Ensure you understand the Celery task flow
   - Consider impact on database schema
 ### Code Conventions
 #### Python Style
 ```python
 # Use Black formatting (line length: 120)
 # Use type hints
 def process_document(file_path: str, metadata: Dict[str, Any]) -> DocumentMetadata:
    """
    Process a document and extract metadata.
    Args:
        file_path: Absolute path to the document file
        metadata: Additional metadata to include
    Returns:
        DocumentMetadata object with extracted information
    Raises:
        FileNotFoundError: If file doesn't exist
        ProcessingError: If processing fails
    """
    pass
 # Use descriptive variable names
 user_document_path = Path("/workdir/documents/invoice.pdf")
 ocr_result = extract_text_from_pdf(user_document_path)
 # Prefer explicit over implicit
 if storage_provider == "dropbox":
    upload_to_dropbox(file_path, metadata)
 elif storage_provider == "google_drive":
    upload_to_google_drive(file_path, metadata)
 else:
    raise ValueError(f"Unknown storage provider: {storage_provider}")
 ```
 #### Configuration
 ```python
 # Always use settings from config.py
 from app.config import settings
 # Good
 api_key = settings.openai_api_key
 # Bad - never hardcode
 api_key = "sk-abc123..."
 # Check if optional services are configured
 if settings.dropbox_app_key:
    # Dropbox is configured
    upload_to_dropbox()
 ```
 #### Error Handling
 ```python
 # Use appropriate exception types
 from fastapi import HTTPException, status
 # API endpoints should return HTTP errors
@router.get("/files/{file_id}")
 async def get_file(file_id: int):
    file = get_file_from_db(file_id)
    if not file:
        raise HTTPException(
            status_code=status.HTTP_404_NOT_FOUND,
            detail=f"File with ID {file_id} not found"
        )
    return file
 # Tasks should log and handle errors gracefully
@celery_app.task(bind=True, max_retries=3)
 def process_document_task(self, file_path: str):
    try:
        result = process_document(file_path)
        return result
    except TemporaryError as e:
        logger.warning(f"Temporary error processing {file_path}: {e}")
        raise self.retry(exc=e, countdown=60)
    except PermanentError as e:
        logger.error(f"Permanent error processing {file_path}: {e}")
        # Don't retry permanent errors
        return {"error": str(e)}
 ```
 #### Testing
 ```python
 # Mark tests appropriately
@pytest.mark.unit
 def test_hash_file():
    """Unit test for file hashing utility."""
    pass
@pytest.mark.integration
 def test_upload_api_endpoint(client):
    """Integration test for upload API."""
    pass
@pytest.mark.requires_external
@pytest.mark.skip(reason="Requires OpenAI API key")
 def test_openai_metadata_extraction():
    """Test actual OpenAI integration."""
    pass
 # Use fixtures for common setup
 def test_document_processing(sample_pdf_path, db_session):
    """Test uses fixtures from conftest.py"""
    pass
 ```
 ---
 ## 📝 Common Tasks
 ### Adding a New API Endpoint
 1. Create endpoint in `app/api/`:
 ```python
 # app/api/my_feature.py
 from fastapi import APIRouter, HTTPException
 from app.database import get_db
 from app.models import MyModel
 router = APIRouter(prefix="/api/my-feature", tags=["my-feature"])
@router.get("/")
 async def list_items(db=Depends(get_db)):
    """List all items."""
    items = db.query(MyModel).all()
    return items
 ```
 2. Register router in `app/api/__init__.py`:
 ```python
 from app.api import my_feature
 router.include_router(my_feature.router)
 ```
 3. Add tests in `tests/test_api_my_feature.py`
 ### Adding a New Celery Task
 1. Create task in `app/tasks/`:
 ```python
 # app/tasks/my_task.py
 from app.celery_app import celery_app
 import logging
 logger = logging.getLogger(__name__)
@celery_app.task(bind=True, max_retries=3)
 def my_background_task(self, param: str):
    """
    Description of what this task does.
    Args:
        param: Description of parameter
    """
    try:
        logger.info(f"Processing task with param: {param}")
        # Task logic here
        return {"status": "success"}
    except Exception as e:
        logger.error(f"Task failed: {e}")
        raise self.retry(exc=e, countdown=60)
 ```
 2. Import in `app/tasks/__init__.py`
 3. Add tests in `tests/test_tasks.py`
 ### Adding a Database Model
 1. Define model in `app/models.py`:
 ```python
 class MyModel(Base):
    __tablename__ = "my_table"
    id = Column(Integer, primary_key=True, index=True)
    name = Column(String, nullable=False)
    created_at = Column(DateTime, default=datetime.utcnow)
 ```
 2. Create migration:
 ```bash
 cd /path/to/DocuElevate
 alembic revision --autogenerate -m "Add MyModel table"
 alembic upgrade head
 ```
 3. Add model to tests fixtures
 ### Adding a Storage Provider
 1. Create provider module in `app/tasks/storage/`:
 ```python
 # app/tasks/storage/my_provider.py
 from app.config import settings
 import logging
 logger = logging.getLogger(__name__)
 def upload_to_my_provider(file_path: str, metadata: dict) -> str:
    """
    Upload file to My Provider.
    Args:
        file_path: Local path to file
        metadata: Document metadata
    Returns:
        URL or ID of uploaded file
    Raises:
        ProviderError: If upload fails
    """
    if not settings.my_provider_api_key:
        raise ValueError("MY_PROVIDER_API_KEY not configured")
    # Implementation
    pass
 ```
 2. Add configuration to `app/config.py`:
 ```python
 class Settings(BaseSettings):
    # ... existing settings ...
    my_provider_api_key: Optional[str] = None
    my_provider_endpoint: Optional[str] = None
 ```
 3. Add to `.env.demo`:
 ```bash
 # My Provider
 MY_PROVIDER_API_KEY=your_api_key_here
 MY_PROVIDER_ENDPOINT=https://api.myprovider.com
 ```
 4. Add validator in `app/utils/config_validator/`
 5. Add tests with mocked API calls

 ## 🔒 Security Best Practices
 ### What to NEVER Do
 - ❌ Hardcode API keys, passwords, or secrets
 - ❌ Log sensitive data (passwords, tokens, API keys)
 - ❌ Accept unsanitized user input for file paths
 - ❌ Disable security features without documentation
 - ❌ Commit `.env` files or credentials
 ### What to ALWAYS Do
 - ✅ Use `settings` from `app/config.py` for all configuration
 - ✅ Validate and sanitize all user inputs
 - ✅ Use parameterized database queries (SQLAlchemy handles this)
 - ✅ Check file paths for directory traversal (`Path.resolve()`)
 - ✅ Use appropriate HTTP status codes (401, 403, 404, etc.)
 - ✅ Log security-relevant events
 - ✅ Add rate limiting for sensitive endpoints
 - ✅ Use HTTPS in production (documented in deployment guide)
 ### Input Validation Example
 ```python
 from pathlib import Path
 from fastapi import HTTPException, status
 def validate_file_path(file_path: str, base_dir: str = "/workdir") -> Path:
    """Validate file path is within allowed directory."""
    try:
        path = Path(file_path).resolve()
        base = Path(base_dir).resolve()
        # Ensure path is within base directory
        if not path.is_relative_to(base):
            raise ValueError("Path outside allowed directory")
        return path
    except Exception as e:
        raise HTTPException(
            status_code=status.HTTP_400_BAD_REQUEST,
            detail=f"Invalid file path: {e}"
        )
 ```
 ---
 ## 🧪 Testing Strategy
 ### Test Coverage Goals
 - **Target:** 80% overall coverage
 - **Critical modules:** 90%+ (auth, config, database)
 - **Tasks:** 70%+ (complex to test with external services)
 - **API endpoints:** 85%+
 ### Test Types
 ```python
 # Unit tests - fast, isolated, no external dependencies
@pytest.mark.unit
 def test_hash_file_empty(tmp_path):
    """Test hashing an empty file."""
    file = tmp_path / "empty.txt"
    file.write_text("")
    assert hash_file(str(file)) == "expected_hash"
 # Integration tests - test multiple components together
@pytest.mark.integration
 def test_upload_and_process(client, sample_pdf):
    """Test full upload and processing flow."""
    response = client.post("/api/upload", files={"file": sample_pdf})
    assert response.status_code == 200
 # External service tests - skipped by default
@pytest.mark.requires_external
@pytest.mark.skipif(not os.getenv("OPENAI_API_KEY"), reason="No API key")
 def test_real_openai_extraction():
    """Test actual OpenAI API (skipped in CI)."""
    pass
 ```
 ### Running Tests
 ```bash
 # All tests
 pytest
 # Specific category
 pytest -m unit
 pytest -m integration
 # With coverage
 pytest --cov=app --cov-report=html
 # Specific file
 pytest tests/test_api.py -v
 # Skip external services
 pytest -m "not requires_external"
 ```
 ---
 ## 🚀 Performance Considerations
 ### Async/Await
 - FastAPI endpoints are async by default
 - Use `async def` for I/O-bound operations
 - Use regular `def` for CPU-bound operations
 ```python
 # Good - async for I/O
@router.get("/files")
 async def list_files(db: Session = Depends(get_db)):
    files = db.query(FileRecord).all()
    return files
 # Also good - sync for CPU-heavy
@router.post("/hash")
 def hash_large_file(file: UploadFile):
    return compute_hash(file.file.read())
 ```
 ### Database Queries
 ```python
 # Good - single query with join
 files = db.query(FileRecord).options(
    joinedload(FileRecord.metadata)
 ).filter(FileRecord.user_id == user_id).all()
 # Bad - N+1 queries
 files = db.query(FileRecord).filter(FileRecord.user_id == user_id).all()
 for file in files:
    metadata = file.metadata  # Triggers separate query each time
 ```
 ### Celery Tasks
 ```python
 # Long-running tasks should update progress
@celery_app.task(bind=True)
 def process_large_batch(self, file_ids: List[int]):
    total = len(file_ids)
    for i, file_id in enumerate(file_ids):
        process_file(file_id)
        self.update_state(
            state='PROGRESS',
            meta={'current': i + 1, 'total': total}
        )
 ```
 ---
 ## 📚 Documentation Requirements
 ### Code Documentation
 ```python
 def complex_function(param1: str, param2: int = 10) -> Dict[str, Any]:
    """
    One-line summary of what the function does.
    More detailed explanation if needed. Can span multiple
    lines and include examples.
    Args:
        param1: Description of param1
        param2: Description of param2, defaults to 10
    Returns:
        Dictionary containing:
            - key1: Description
            - key2: Description
    Raises:
        ValueError: If param1 is empty
        FileNotFoundError: If file doesn't exist
    Examples:
        >>> result = complex_function("test", 5)
        >>> print(result['key1'])
        'value'
    """
    pass
 ```
 ### API Documentation
 - Use FastAPI's automatic OpenAPI generation
 - Add descriptions to endpoints
 - Document request/response models
 - Include example requests/responses
 ```python
@router.post(
    "/upload",
    response_model=UploadResponse,
    status_code=status.HTTP_201_CREATED,
    summary="Upload a document",
    description="Upload a document for processing. Supports PDF, images, and Office documents.",
    responses={
        201: {"description": "Document uploaded successfully"},
        400: {"description": "Invalid file format"},
        413: {"description": "File too large"},
    }
 )
 async def upload_document(
    file: UploadFile = File(..., description="Document file to upload"),
    tags: List[str] = Query([], description="Optional tags for the document"),
 ):
    """Upload endpoint implementation."""
    pass
 ```
 ---
 ## 🐛 Debugging
 ### Logging
 ```python
 import logging
 logger = logging.getLogger(__name__)
 # Use appropriate log levels
 logger.debug("Detailed information for debugging")
 logger.info("General information about operation")
 logger.warning("Warning about potential issue")
 logger.error("Error that needs attention")
 logger.critical("Critical error that needs immediate attention")
 # Include context in logs
 logger.info(f"Processing document: {file_id}, user: {user_id}")
 # Don't log sensitive data
 logger.info(f"User authenticated")  # Good
 logger.info(f"Password: {password}")  # BAD!
 ```
 ### Common Issues
 1. **Import Errors**
   - Check if module is in `__init__.py`
   - Verify Python path includes project root
   - Look for circular imports
 2. **Database Issues**
   - Check if migrations are up to date: `alembic upgrade head`
   - Verify DATABASE_URL is set correctly
   - Check if tables exist: `sqlite3 app/database.db .schema`
 3. **Celery Issues**
   - Verify Redis is running: `redis-cli ping`
   - Check Celery worker logs
   - Ensure tasks are imported in `celery_worker.py`
 4. **Test Failures**
   - Check if test database is clean (use fixtures)
   - Verify environment variables are set in `conftest.py`
   - Run single test to isolate issue: `pytest tests/test_file.py::test_name -v`

 # Security Audit Report
 **Date:** 2026-02-06  
 **Status:** Completed Initial Assessment
 ## Executive Summary
 This document tracks security vulnerabilities found in DocuElevate and their remediation status.
 ## Critical Vulnerabilities (Fixed) ✅
 ### 1. Outdated Authlib with Known Vulnerabilities
 **Status:** ✅ FIXED  
 **Severity:** HIGH  
 **Description:** Authlib version 1.3.2 had two critical vulnerabilities:
 - CVE: Denial of Service via Oversized JOSE Segments
 - CVE: JWS/JWT accepts unknown crit headers (RFC violation → possible authz bypass)
 **Fix:** Updated `requirements.txt` to require `authlib>=1.6.5`
 ### 2. Starlette DoS Vulnerability
 **Status:** ✅ FIXED  
 **Severity:** MEDIUM  
 **Description:** Starlette 0.41.3 vulnerable to O(n^2) DoS via Range header merging in `FileResponse`
 **Fix:** Updated `requirements.txt` to require `starlette>=0.49.1`
 ### 3. Weak SESSION_SECRET Default
 **Status:** ✅ FIXED  
 **Severity:** HIGH  
 **Description:** Default SESSION_SECRET value in `app/main.py` was a predictable string that could be exploited if not overridden
 **Fix:** 
 - Enhanced validation in `app/main.py` to raise error if auth is enabled without proper secret
 - Updated default to be clearly marked as insecure for development only
 - Added generation instructions in error message
 ## Medium Risk Issues (Fixed) ✅
 ### 4. Insufficient .gitignore Protection
 **Status:** ✅ FIXED  
 **Severity:** MEDIUM  
 **Description:** .gitignore didn't adequately protect against accidentally committing sensitive files (credentials, private keys, secrets)
 **Fix:** Enhanced `.gitignore` with comprehensive patterns for:
 - Various environment file formats
 - Credential JSON files
 - Private keys (.pem, .key, .pfx, etc.)
 - SSH keys
 - Explicit exclusion of patterns where needed
 ## Best Practices Implemented
 ### Dependency Management
 - ✅ Version pinning for security-critical packages (authlib, starlette)
 - ✅ Advisory database checks integrated into development workflow
 - ⏳ TODO: Add automated dependency vulnerability scanning in CI/CD
 ### Authentication & Secrets
 - ✅ Strong validation for SESSION_SECRET (minimum 32 characters)
 - ✅ Error-on-missing for critical security settings when auth enabled
 - ✅ Clear documentation of secret generation methods
 - ✅ .env.demo file for configuration examples (no real secrets)
 ### Configuration Security
 - ✅ All secrets loaded from environment variables
 - ✅ No hardcoded credentials in codebase
 - ✅ Proper masking in configuration validators
 ## Ongoing Security Measures
 ### CI/CD Security
 - ⏳ **TODO:** Add CodeQL scanning to GitHub Actions
 - ⏳ **TODO:** Add Bandit (Python security linter) to CI pipeline
 - ⏳ **TODO:** Add dependency vulnerability scanning (Safety, pip-audit)
 - ⏳ **TODO:** Make security scans blocking (fail on critical issues)
 ### Code Security
 - ⏳ **TODO:** Implement rate limiting on API endpoints
 - ⏳ **TODO:** Add CSRF protection for state-changing operations
 - ⏳ **TODO:** Implement request size limits
 - ⏳ **TODO:** Add input sanitization for all user inputs
 - ⏳ **TODO:** Implement proper API key rotation mechanisms
 ### Infrastructure Security
 - ✅ TrustedHostMiddleware configured
 - ✅ ProxyHeadersMiddleware for reverse proxy setup
 - ⏳ **TODO:** Add security headers (HSTS, CSP, X-Frame-Options)
 - ⏳ **TODO:** Implement proper CORS configuration
 - ⏳ **TODO:** Add request logging with sensitive data masking
 ## Recommendations
 ### High Priority
 1. **Enable CodeQL scanning** - Automated security vulnerability detection
 2. **Implement rate limiting** - Prevent abuse and DoS attacks
 3. **Add comprehensive input validation** - Prevent injection attacks
 4. **Implement API authentication** - Secure all API endpoints properly
 ### Medium Priority
 1. **Add security headers** - Improve browser-side security
 2. **Implement audit logging** - Track security-relevant events
 3. **Add automated security testing** - Integration with CI/CD
 4. **Document security architecture** - Security design decisions
 ### Low Priority
 1. **Security training documentation** - For contributors
 2. **Penetration testing** - Professional security assessment
 3. **Bug bounty program** - Community security contributions
