My "anti Claude-speak" system prompt

A user shared an "anti Claude-speak" system prompt designed to improve clarity and conciseness. The prompt emphasizes active voice, imperatives for rules, and using verbs over abstract nouns. It also advises one idea per sentence, concrete language, and avoiding em dashes, filler words, and rhetorical devices unless essential. Prohibited elements include defining by negation, using counts as rhetorical devices, tautologies, explaining rhetorical moves, sentence fragments, and overly abstract nouns like "wedge" or "substrate."

This prompt stands out by explicitly listing what not to do, unlike many guides that only focus on positive instructions for AI communication.
