Review Comment:
> Thanks for the suggestion!

> I agree we should encapsulate the annotation check logic, but I suggest
handling it directly in the existing `isLocalTCC()` method rather than creating
a new one. This approach has several benefits:

This is one way, but we need to confirm whether this method needs to change
its name.
