To prevent blocking the Unity main thread, apply non-blocking async patterns using C# async/await, UniTask, or coroutines for scene and asset loading operations. This skill provides ready-made AsyncLoader utilities to execute long-running tasks safely without freezing the main thread.

The best way to handle async network requests and file I/O in Unity is using UniTask or async/await with CancellationToken patterns. This skill provides templates for network requests with timeouts and file operations that ensure main-thread safety throughout the execution.

To use CancellationToken with async tasks in Unity and prevent leaked tasks, apply DestroyCancellationToken in AsyncMonoBehaviour and safe RunAsync helpers. This skill provides cancellation patterns that ensure tasks are properly cancelled when GameObjects are destroyed during scene transitions.

Choosing between coroutines, UniTask, and async/await in Unity depends on your allocation tolerance and main-thread safety needs. This skill provides guidance on trade-offs for each approach, helping you select the right pattern for sequential or parallel async tasks.

To bridge legacy coroutines to awaitable Tasks or UniTask in Unity, use CoroutineToTask utilities provided by this skill. These helpers convert existing coroutine implementations into awaitable operations while maintaining main-thread safety and cancellation support.

To report progress during awaitable scene loading in Unity, apply AsyncOperation utilities with progress reporting and cancellation tokens. This skill provides templates for sequential and parallel asset loading that report progress while ensuring the main thread remains responsive.
