Implements high-performance Python concurrency using modern structured patterns, TaskGroups, and robust error handling for Python 3.11+ applications.

This skill equips Claude with specialized knowledge for architecting robust asynchronous Python applications using modern 3.11+ standards. It prioritizes structured concurrency through TaskGroups over legacy patterns, ensuring superior task management, automatic cancellation propagation, and sophisticated exception handling with ExceptionGroups. Whether building high-throughput backend services, managing complex API integrations, or bridging synchronous code to async loops, this skill provides production-ready patterns to prevent memory leaks, avoid event loop blocking, and ensure reliable service execution.
