Modern Python asyncio patterns using structured concurrency, TaskGroup, and Python 3.11+ features.

| Task spawning | TaskGroup not gather() | Structured concurrency, auto-cancellation | | Timeouts | asyncio.timeout() context manager | Composable, cancels on exit | | Concurrency limit | asyncio.Semaphore | Prevents resource exhaustion | | Sync bridge | asyncio.tothread() | Clean API, manages thread pool |

| Exception handling | except with ExceptionGroup | Handle multiple failures properly | | Cancellation | Always re-raise CancelledError | Breaking this breaks TaskGroup/timeout |

Python asyncio patterns with TaskGroup, structured concurrency, and modern 3.11+ features. Use when implementing concurrent operations, async context managers, or high-performance async services. Source: yonatangross/skillforge-claude-plugin.
