If you want to exempt, say, the addition of library code from your
conditions on modifications in general, you need to add language
in the license text that says so explicitly. (And doing so may not
be a trivial task if you do not want to introduce loopholes that
allow people to disguise essential part of their contributions as
undisclosed library code).
