If it's something that can be solved by "reading the license and license boilerplate", then there's no need for guidelines.

This is the point of code review, when you noticed that boilerplate is not the one we usually use / incorrect copyright/license attribute. There is no guidelines, rather you just need to tell what is the right way.
