Python

This is a strict, opinionated Python setup centered on modern tooling and test-driven development. It enforces type hints everywhere with mypy in strict mode, uses ruff for linting and formatting, and expects 80% test coverage via pytest. The structure separates pure business logic from side effects, which is clean but requires discipline. You get pre-commit hooks, GitHub Actions configs, and patterns like dependency injection and Pydantic validation out of the box. If you're starting a greenfield Python project or want to tighten up an existing one, this gives you a production-ready foundation. The anti-patterns list alone is worth having around.
