I see you frequently say FILEPATH_OR_BUFFER with no explanation that the path includes the file name not in the variable name or in the explanation. One can read this and understant it as only the file path where it's maybe more true that it's file name and optionally a path where if the path is not there it uses the working directory?
I think it's many places.
This is a request to fix documentation, not code.
