Modern Python 3.14+ Development

About

This skill equips Claude with the specialized expertise required to write cutting-edge Python code leveraging features from version 3.14 and beyond. It enforces a philosophy of 'stdlib first,' utilizing the uv and ruff toolchain for peak performance while prioritizing structural typing through Protocols over traditional Abstract Base Classes. By implementing flat control flow, pattern matching, and strict type hinting, it ensures the creation of clean, maintainable, and future-proof Python scripts, CLI tools, and backend services optimized for the latest interpreter features.

Key Features

• Implements Protocol-based structural typing for flexible dependency injection
• 8 GitHub stars
• Utilizes Python 3.14 features like deferred annotations and template strings
• Enforces strict type hinting without the use of 'Any'
• Optimizes code for uv and ruff toolchains with flat control flow patterns
• Prioritizes Python standard library and mature dependencies

Use Cases

• Building high-performance CLI tools with minimal external footprint
• Migrating legacy Python codebases to modern 3.14+ standards
• Designing type-safe microservices with structural typing and async patterns
