How does it handle data validation?

It leverages Pydantic v2.9 patterns, including model_validate patterns, cross-field validation using model_validator, and reusable Annotated types.

Is it optimized for async development?

Yes, it specializes in async patterns for FastAPI, SQLAlchemy 2.0, and comprehensive async testing using pytest-asyncio and httpx.

Can it help with modern Python package managers?

Absolutely. It includes best practices and configuration patterns for uv, Poetry, and standard pip-based workflows using pyproject.toml.

Does this skill support Python 3.13's experimental features?

Yes, it provides specific guidance for utilizing the new JIT compiler (PEP 744) and the experimental GIL-free mode (PEP 703) for multi-threaded performance.
