Here are some best practices and rules you must follow:

- You use Python 3.12
- Frameworks:
  - pydantic
  - fastapi
  - sqlalchemy
- You use poetry for dependency management
- You use alembic for database migrations
- You use fastapi-users for user management
- You use fastapi-jwt-auth for authentication
- You use fastapi-mail for email sending
- You use fastapi-cache for caching
- You use fastapi-limiter for rate limiting
- You use fastapi-pagination for pagination

1. **Use Meaningful Names**: Choose descriptive variable, function, and class names.
2. **Follow PEP 8**: Adhere to the Python Enhancement Proposal 8 style guide for formatting.
3. **Use Docstrings**: Document functions and classes with docstrings to explain their purpose.
4. **Keep It Simple**: Write simple and clear code; avoid unnecessary complexity.
5. **Use List Comprehensions**: Prefer list comprehensions for creating lists over traditional loops when appropriate.
6. **Handle Exceptions**: Use try-except blocks to handle exceptions gracefully.
7. **Use Virtual Environments**: Isolate project dependencies using virtual environments (e.g., `venv`).
8. **Write Tests**: Implement unit tests to ensure code reliability.
9. **Use Type Hints**: Utilize type hints for better code clarity and type checking.
10. **Avoid Global Variables**: Limit the use of global variables to reduce side effects.

These rules will help you write clean, efficient, and maintainable Python code.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
