Does this skill work with older versions of Python?

While it covers general async concepts, it specifically focuses on features introduced in Python 3.11+, such as TaskGroup, ExceptionGroups, and the native timeout context manager.

Why should I use TaskGroup instead of asyncio.gather?

TaskGroup implements structured concurrency, ensuring that if one sub-task fails, all other tasks in the group are automatically cancelled. This prevents 'leaked' background tasks and ensures more predictable error propagation.

How do I handle synchronous blocking calls in an async environment?

The skill provides patterns for using asyncio.to_thread and ThreadPoolExecutors to run CPU-bound or blocking I/O code without freezing the main event loop.

What is the rule for handling CancelledError?

You should never swallow a CancelledError. This skill enforces the pattern of catching it only for necessary cleanup and then always re-raising it to allow the structured concurrency hierarchy to function correctly.

API 开发

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.
