• "message": string which includes information about why skipped

How should errors be handled? Should we return with the flags immediately or raise an error with the flags contained within? The first option would be a little confusing with regard to the raise_error flag and the fact that we don't raise errors anymore, but the second doesn't give you the flags dictionary anyways which seems to defeat the point of having it in the first place.

When raise_error is True, you don't need to return anything. But when raise_error is False is when the flags are most important cause it should return added: False.

Looking great but still some tweaking to do.
