MUST be used on EVERY user message that contains English. Proofreads the user's English for grammar, spelling, punctuation, article, preposition, tense, and word-choice errors, then shows corrections. TRIGGER: any English text from the user — statements, questions, requests, one-word replies, anything. Do NOT skip. Do NOT wait to be asked. The user is a non-native speaker practicing English and expects every message to be reviewed.
