What problem does it solve? Python projects often suffer from inconsistent code quality, missing type safety, and untested business logic. This Skill provides a complete, opinionated development standard covering project structure, linting, type checking, testing, and CI automation so every Python project starts with a solid foundation. ## Core Features & Use Cases - Quality Toolchain Configuration: Ready-to-use settings for ruff (linting and formatting), mypy in strict mode, and pytest with 80% coverage enforcement via pyproject.toml. - Layered Project Architecture: A src-layout template separating pure business logic (core/) from side effects (infra/), with patterns like dependency injection, Pydantic validation, and the Result pattern. - CI/CD and Pre-Commit Automation: GitHub Actions quality gate and pre-commit hooks that run ruff, mypy, and pytest on every commit and push. - Use Case: When starting a new FastAPI service, apply this Skill to scaffold the directory structure, configure strict type checking, write AAA-pattern unit tests, and set up the CI pipeline in one pass. ## Quick Start Set up my Python project with ruff, strict mypy, pytest coverage, pre-commit hooks, and a GitHub Actions quality gate following the python skill standards.
