Claude 3 System Prompts for Design

Has anyone tried utilizing Claude’s system prompts effectively for design tasks? I’ve found that specifying “Act as a senior UX designer specializing in mobile app interfaces” within Claude 3 Opus consistently yields more detailed and contextually relevant output when generating wireframe ideas – particularly when requesting variations based on accessibility guidelines. I’m curious to see if others have discovered specific prompt structures that unlock its full potential for rapid prototyping.
