I can't get the prompt because I'm on my work computer but I have about a three-quarter-page instruction set in the settings of cursor, it asks clarifying questions a LOT now, and is pretty liberal with adding in commented pseudo-code for stuff it isn't sure about. You can still trip it up if you try, but it's a lot better than stock. This is with Sonnet 3.5 agent chats (composer I think it's called?)

I actually cancelled by Anthropic subscription when I started using cursor because I only ever used Claude for code generation anyway so now I just do it within the IDE.
