This skill provides comprehensive guidance on Python's asyncio framework for modern concurrent programming using async/await syntax. It covers core concepts like event loops, tasks, and coroutines along with practical implementations including aiohttp for async HTTP operations and FastAPI async patterns. Use it when building concurrent I/O-bound applications, parallel API clients, real-time systems, or async web servers.

This skill provides guidance for using Flask, a lightweight Python web framework ideal for building microservices, REST APIs, and flexible web applications. It helps developers when they need a minimal, extensible framework over a batteries-included solution, especially for rapid prototyping. The skill covers core concepts like routing with decorators, using Blueprints for modularity, and leveraging its extensive extension ecosystem.

mypy is a static type checker for Python that enables gradual typing with type hints and comprehensive type safety. Use it to add type safety to Python projects, enforce type checking in CI/CD, and refactor code with type annotations. It supports strict mode, Protocol types, and integrates with frameworks like FastAPI and Django.

This skill enables professional Python testing with pytest, providing fixtures, parametrization, and mocking capabilities. It's ideal for writing unit/integration tests, TDD workflows, and testing async code across frameworks like FastAPI, Django, and Flask. Developers can quickly set up tests with fixtures, use parametrization for multiple scenarios, and run comprehensive test suites.
