This one takes a strong stance right up front: consistency over creativity. It's built around the idea that visual design should serve the user experience, not the other way around. From what's visible, it starts with color systems and theory fundamentals, which suggests a structured, educational approach rather than a quick reference. The core principle that "great design is invisible" tells you the philosophy here. It's from daffy0208's ai-dev-standards repo with 28 stars and has passed all three security audits. If you want your AI to follow a disciplined design system instead of making arbitrary visual choices, this gives it a framework to work within.
