@AbleArcher interesting ideas, were you thinking of preset rules that could be applied at folder level, or a chat level or a prompt level? I am assuming you already know about the .cursorrules file that operates at the folder level?
A bit off topic:
I could be wrong, but I think GPT4o, as experienced in Chat GPT Plus, has a lot more verbose responses than the previous model and, perhaps as a way of keeping important information in context, each reply to my code related questions seems to have three or four sections: 1) a response 2) a more detailed response 3) steps to implement 4) a summary. Quite often these sections are almost identical. So I often find myself saying something like ‘please be succinct and don’t repeat yourself’ or ‘don’t generate any code, let’s just talk about the logic’. So I could personally see a use case for having some sort of ‘canned prompts’ available at different levels of the chat.
