In provider method

    AnotherProvider.provide_a(..., b: SomeProvider.b, ...) -> int

Parameter 'b' is a resource from a base provider SomeProvider

    SomeProvider.b = Resource(int, ResourceKind.PRIVATE)

Referring providers of a parent provider is not supported. It's likely that you
intended to refer to AnotherProvider.b. If that's the case, you should write it
as:

    AnotherProvider.provide_a(..., b: int, ...) -> int

AnotherProvider: "src/seamful/provider/test_provider.py"
