I greatly prefer extensive negotiations, myself. The negotiations often give me time to gauge the strength of my opponent and whether it is a worthwhile cause. They also let me throw in a few helpful exceptions, such as utterdarkness.

But one of the clearest shorthand abbreviations for a NAP was a 10+3 NAP. The first was minimum length and the latter was warning. To even further lessen the possibility of confusion, you could go #M+#W. For instance, a nonagression pact that can be canceled at any time with three turns of warning would be notarized 0M+3W.
