Metadata in Building custom rules for workflow analyzer

[Sebastian_Silva1 (Sebastián Silva)]

Hello, my question is about building custom rules in uipath for best practice analysis, my question is about the step shown in the picture

Does this step is required? I also doesn’t understand how this step may affect, or how to even do it, because it doesn’t have a code example I doesn’t understand it, thanks.
