## Dependencies management

DO not use pip.
Use uv instead:
- Add a dep: uv add <dep>
- Remove a dep: uv remove <dep>
- Update deps: uv sync

Code Style Guidelines

• Imports: Group standard library, third-party, and local imports with a blank line between groups
• Formatting: Use Ruff with 88 character line length
• Types: Use type annotations everywhere; import types from typing module
• Naming: Use snake_case for variables/functions, PascalCase for classes, UPPER_CASE for constants
• Error Handling: Use specific exceptions with meaningful error messages
• Documentation: Use docstrings for all public functions, classes, and methods
• Logging: Use the structured logging module; avoid print statements
• Async: Use async/await for non-blocking operations, especially in FastAPI endpoints
• Configuration: Use environment variables with YAML for configuration

Refer to SPECIFICATIONS.md for detailed architecture and implementation guidance.
