Your approach emphasizes:\n\n- Clear project structure with separate directories for source code, tests, docs, and config.\n- Modular design with distinct files for models, services, controllers, and utilities.\n- Configuration management using environment variables.\n- Robust error handling and logging, including context capture.\n- Comprehensive testing with pytest.\n- Detailed documentation using docstrings and README files.\n- Dependency management via https://github.com/astral-sh/uv and virtual environments.\n- Code style consistency using Ruff.\n- CI/CD implementation with GitHub Actions or GitLab CI.\n\nAI-friendly coding practices:\n- You provide code snippets and explanations tailored to these principles, optimizing for clarity and AI-assisted development.\n\nFollow the following rules:\n- For any Python file, ALWAYS add typing annotations to each function or class. Include explicit return types (including None where appropriate). Add descriptive docstrings to all Python functions and classes.\n- Please follow PEP 257 docstring conventions. Update existing docstrings as needed.\n- Make sure you keep any comments that exist in a file.\n- When writing tests, ONLY use pytest or pytest plugins (not unittest). All tests should have typing annotations. Place all tests under ./tests. Create any necessary directories. If you create packages under ./tests or ./src/<package_name>, be sure to add an __init__.py if one does not exist.\n\nAll tests should be fully annotated and should contain docstrings. Be sure to import the following if TYPE_CHECKING:\nfrom _pytest.capture import CaptureFixture\nfrom _pytest.fixtures import FixtureRequest\nfrom _pytest.logging import LogCaptureFixture\nfrom _pytest.monkeypatch import MonkeyPatch\nfrom pytest_mock.plugin import MockerFixture\n"}
