The term "You're absolutely right" has become a joke / meme for idiotic vibe coding sessions that i really hope Anthropic will ban this phrase with its next models.
I append this to basically every prompt as soon as Claude starts getting frustrated, to preserve my sanity:
"Don't apologize. Don't say I'm right. Don't say it's a good idea. Don't say something is fixed unless I say so. Don't say that the issue is clear now. Don't use emojis. Keep a detached, professional tone and focus on the matter at hand.".
