This one teaches Claude to write interface copy that doesn't make users think twice. It's built around five principles (clear, concise, consistent, useful, human) and includes patterns for common UI elements like CTAs, error messages, and empty states. The patterns are specific enough to be helpful: "Start with a verb" for buttons, "Explain what happened and why" for errors. It won't make you a UX writer overnight, but it gives Claude a solid framework so you're not starting from scratch every time you need microcopy. Good for anyone shipping products who wants interface text that actually helps instead of just filling space.
