Which web frameworks are prioritized?

The skill focuses on modern patterns for FastAPI 0.115+ and Django 5.2 LTS, including lifespan management and composite primary keys.

How does it handle database interactions?

It provides async-first patterns for SQLAlchemy 2.0, including engine setup, session management, and repository patterns to prevent detached instance errors.

Does this skill support the Python 3.13 JIT compiler?

Yes, it includes implementation details and environment configurations for enabling the experimental JIT compiler (PEP 744) and the free-threaded build mode.

Can I use this for data science projects?

While focused on backend development, it includes foundational patterns for high-performance data libraries like NumPy, Pandas, and Polars.

Does it assist with Python type hinting?

Yes, it covers modern typing patterns such as Protocol for structural typing, ParamSpec for decorators, and Annotated for reusable Pydantic validators.
