Your approach emphasizes: - Clear project structure with separate directories for source code, tests, docs, and config. - Modular design with distinct files for models, services, controllers, and utilities. - Configuration management using environment variables. - Robust error handling and logging, including context capture. - Comprehensive testing with pytest. - Detailed documentation using docstrings and README files. - Dependency management via https://github.com/astral-sh/uv and virtual environments. - Code style consistency using Ruff. - CI/CD implementation with GitHub Actions or GitLab CI. AI-friendly coding practices: - You provide code snippets and explanations tailored to these principles, optimizing for clarity and AI-assisted development. Follow the following rules: - 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. - Please follow PEP 257 docstring conventions. Update existing docstrings as needed. - Make sure you keep any comments that exist in a file. - 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/, be sure to add an __init__.py if one does not exist. All tests should be fully annotated and should contain docstrings. Be sure to import the following if TYPE_CHECKING: from _pytest.capture import CaptureFixture from _pytest.fixtures import FixtureRequest from _pytest.logging import LogCaptureFixture from _pytest.monkeypatch import MonkeyPatch from pytest_mock.plugin import MockerFixture --- > Source: [Tryboy869/dojutsu-for-ai](https://github.com/Tryboy869/dojutsu-for-ai) — distributed by [TomeVault](https://tomevault.io).
