“not very persuasive” is not a sentence fragment. Sentences need a subject, verb, and a complete thought.
“Don’t do that” has an implied subject of (you). “Not very persuasive” shares the same type implied subject and is a complete sentence.
Bonus fun fact, the shortest complete sentence in the English language is “I am” but not “I’m” because contractions are inherently dependent.
