SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Writing production-ready Python often becomes inconsistent and error-prone without strong patterns for typing, validation, testing, and project tooling.

Core Features & Use Cases

  • Type Hints & Structure: Establish a maintainable project layout and use modern type annotations to reduce runtime surprises.
  • Pydantic Validation: Define robust request/response models with constraints to enforce correctness at boundaries.
  • Testing & Tooling: Use pytest, ruff, mypy, and pre-commit to catch regressions early and keep code quality high.
  • Async & Framework Guidance: Apply patterns for async I/O and common framework setups (FastAPI, Django, Flask) to ship APIs confidently.

Use Case: You’re building a FastAPI endpoint that accepts user input and must guarantee correctness; use this skill to define Pydantic models with constraints, add type-safe handlers, and cover behavior with pytest.

Quick Start

Ask the skill to generate a complete minimal Python project scaffold (pyproject.toml, ruff, mypy, pytest setup, src/ and tests/ structure) plus an example Pydantic model with corresponding pytest tests.

FAQPage Schema
How do I structure a production-ready FastAPI project with type hints and validation?

Structure a production-ready FastAPI project by establishing a maintainable src/ and tests/ layout, using modern type annotations, and defining Pydantic models with constraints to enforce data correctness at API boundaries.

What is the best way to configure pytest, mypy, and ruff for a Python service?

The best way to configure pytest, mypy, and ruff is through a standardized pyproject.toml scaffold that automates quality gates via pre-commit, catching regressions early while maintaining high code quality.

Can I use Pydantic constraints to validate request models in Django or Flask?

Yes, you can define robust request and response models with Pydantic constraints to enforce validation correctness, applying these patterns alongside common framework setups for Django, Flask, and FastAPI services.

How do I add type-safe handlers and pytest coverage to an async I/O Python backend?

Add type-safe handlers and pytest coverage to an async I/O backend by applying async patterns, using pytest-cov for comprehensive coverage measurement, and enforcing static typing with mypy to reduce runtime surprises.

Do I need pre-commit hooks to maintain mypy and ruff quality gates in Python?

You need pre-commit hooks to automate mypy and ruff quality gates, ensuring that static typing and linting checks catch regressions consistently before code is committed to the Python project.
