Review C# async workflows
Check async C# code for deadlock risks, blocking calls, weak cancellation flow, unnecessary allocations, and exception-handling mistakes.
When to Use This Skill
Use this when code adds async behavior, background work, I/O, or concurrency and you want a targeted pass on correctness and runtime behavior.
Workflow Overview
- Look for blocking calls, fire-and-forget work, and Task usage that breaks async end-to-end behavior.
- Check naming, return types, cancellation propagation, and exception handling for consistency with the surrounding code.
- Prefer simple async fixes that preserve behavior before reaching for advanced task patterns.
- Call out hot-path allocation or parallelization opportunities only when they are likely to matter in practice.
Examples
- Review this C# async path for blocking or deadlock risks.
- Check whether cancellation tokens are flowing through the new service calls.
- Evaluate a background workflow for Task misuse and exception handling gaps.
