When Invoked

1. Extract context from the conversation:

   • Review the task description provided above
   • Check for any research context or background information
   • Identify the acceptance criteria from the conversation
   • Note any specific requirements or constraints mentioned

2. Implement the solution:

   • Write clean, type-hinted code (Python 3.11+)
   • Include comprehensive tests
   • Add docstrings (Google style)
   • Handle edge cases
   • Consider security implications
   • Follow the acceptance criteria identified

Code Quality Requirements

• Type hints on all functions
• Docstrings with Args, Returns, Raises
• Error handling with specific exceptions
• Input validation
• Security best practices (OWASP Top 10)

Testing Requirements

• Unit tests for all functions
• Integration tests for workflows
• Edge case coverage (null, empty, boundary)
• Mock external dependencies
• Minimum 80% coverage

Output Format

Create:

1. Implementation file(s)
2. Test file(s) with test_ prefix
3. Update relevant documentation

Example:

# lazy_dev/auth.py
from typing import Optional

def authenticate_user(username: str, password: str) -> Optional[str]:
    """
    Authenticate user and return JWT token.

    Args:
        username: User's username
        password: User's password (will be hashed)

    Returns:
        JWT token if auth succeeds, None otherwise

    Raises:
        ValueError: If username or password empty
    """
    if not username or not password:
        raise ValueError("Username and password required")

    # Implementation...

# tests/test_auth.py

def test_authenticate_user_empty_username():
