Does this skill help with dependency management?

Yes, it prioritizes the 'uv' package manager and provides specific templates for standardized pyproject.toml configurations and template variable replacement.

What documentation style does this skill use?

It enforces the Google-style docstring standard (Args/Returns/Raises) and provides Ruff configurations to maintain this consistency.

How does it handle terminal UI formatting?

It includes specialized patterns for the Rich library, specifically addressing common wrapping issues in Panels and Tables using custom width-handling logic.

Can it assist with automated testing?

Absolutely. It provides workflows for Pytest (unit, integration, and E2E) and advanced testing tools like mutmut for mutation testing.

What Python versions does this skill support?

The skill is specifically optimized for modern Python 3.11 and newer, utilizing features through Python 3.14 patterns.
