What version of Python does this skill target?

This skill specifically targets Python 3.14 and above, utilizing the latest features like deferred annotations, template strings, and the free-threaded build.

What is the preferred approach to typing in this skill?

The skill enforces strict type hinting (avoiding 'Any') and prefers structural typing using Protocols over traditional inheritance-based Abstract Base Classes.

Does this skill help with code formatting and linting?

Yes, it is pre-configured to work with the Ruff toolchain for lightning-fast linting, autofixing, and formatting according to idiomatic standards.

How does it handle complex conditional logic?

It promotes 'Flat Control Flow' by using guard clauses, early returns, and Python's native pattern matching to keep nesting to a maximum of two levels.

How does this skill handle dependency management?

It favors the Python standard library first and recommends the modern uv toolchain for managing external dependencies and environment synchronization.
