What problem does it solve?
It reduces the risk, time, and technical debt of building Python 3.11+ applications by providing prescriptive, production-grade patterns for type safety, async-first design, testing, and packaging. It helps teams achieve consistent public API typing, reliable async I/O, and repeatable quality checks so releases are maintainable and auditable.
Core Features & Use Cases
- Type safety & interfaces: Design protocols, dataclasses, and type aliases to ensure complete type coverage and clear public APIs.
- Async-first patterns: Convert I/O-bound code to async/await, use TaskGroup and async context managers, and adopt structured concurrency.
- Testing & tooling: Create pytest suites with fixtures and mocking, enforce mypy --strict, and apply black and ruff formatting in CI.
- Use Case: Refactor a synchronous data ingestion service to async TaskGroup processing, add type annotations across modules, implement pytest coverage, and validate with mypy in the CI pipeline.
Quick Start
Use the python-pro skill to refactor a module to Python 3.11+ with full type annotations, convert blocking I/O to async/await, and add pytest tests plus a mypy --strict configuration.
