Any powerful general/master Prompt for Mistral models?

I know mistral models are kinda mid in quality but i don't care about that (much).

But It's annoying how it generate shorter messages the more i chat with the bot, no matter how long my input is. I can do a simple line or a whopping 4 long paragraphs and it would still act the same.

Other than that, if your suggested prompt does enhance quality, flow, narration and provide a good output structure, it would be nice too
