This brings Nielsen's 10 usability heuristics, design thinking frameworks, and user-centered design principles into your conversations with Claude. You'll get concrete guidance on things like visibility of system status, error prevention, and recognition over recall, plus practical examples for each heuristic. Use it when you're designing interfaces, evaluating usability, planning user research, or need to justify design decisions with established UX frameworks. The skill covers accessibility and inclusive design too, though the source focuses heavily on foundational heuristics. It's genuinely helpful for grounding design discussions in proven principles rather than subjective opinions, especially if you're working without a dedicated UX team.
