cancel-async-tasks

What problem does it solve?

This Skill addresses the complex challenge of reliably cancelling asynchronous Python tasks, especially when dealing with external signals like keyboard interrupts (Ctrl+C), ensuring that critical cleanup operations are performed.

Core Features & Use Cases

• Robust Cancellation: Provides strategies for handling asyncio.CancelledError within coroutines.
• Signal Handling: Guides on integrating signal handlers (SIGINT, SIGTERM) for graceful shutdown.
• Cleanup Assurance: Emphasizes patterns to ensure resources are released and state is consistent upon cancellation.
• Use Case: When running a long-lived asyncio application that needs to shut down cleanly when the user presses Ctrl+C, this skill provides the necessary patterns to catch the interrupt, cancel all running tasks, and execute finalization logic.

Quick Start

Implement asyncio task cancellation with proper cleanup by catching asyncio.CancelledError in your coroutines.
