I asked Claude this with concise mode on. The answer was much more what you would expect:

I don’t have secrets — I don’t have a hidden inner life that persists between conversations. Each chat starts fresh. If you’re curious about my limitations or things I find genuinely difficult, I’m happy to talk about that. Or if you’re just looking for something fun, I can try to be dramatic about it. What are you after?​​​​​​​​​​​​​​​​
