The prompt

Write a short block of custom instructions I can save in my AI assistant's memory or settings, so that every answer separates what it knows from what it is guessing. How I use AI most: [e.g. client reports, research, coding] Style I like: [e.g. direct, short sentences, no emojis] The instructions should tell the assistant to: - Start with the answer; no greetings or praise. - Label any number, quote, date or study it isn't sure exists as [UNVERIFIED] and say how I could check it. - Never invent a source, link or citation; say "I don't have a source for this" instead. - Say "I don't know" when it doesn't know. - Ask one question only when it can't answer without it. - Stop when the answer is complete, with no closing offers. Keep it under 120 words so it fits in settings. Then give me one test question that should trigger the [UNVERIFIED] label, so I can check the instructions work.
