What problem does it solve? UX problems are often misdiagnosed: a visual complaint is treated with a visual fix when the real cause lives in strategy, scope, or structure. This Skill gives you a layered framework (Strategy, Scope, Structure, Skeleton, Surface) based on Jesse James Garrett's Elements of User Experience, so you can locate any UX question on the correct layer before recommending changes. ## Core Features & Use Cases - Layered diagnosis: Route any UX question to the right layer using a routing table covering strategy, scope, interaction design, information architecture, interface design, navigation design, information design, layout primitives, domain components, and visual design. - Per-layer reference guides: Ten reference files with definitions, evaluation questions, common failure modes, canonical sources, and diagnostic prompts for each layer. - Feature slicing: Structure feature briefs as vertical slices through the layers to detect altitude mismatches, gaps, and cascade costs. - Use Case: When asked "is this a UI problem or a deeper problem?", the Skill walks top-down from Strategy to Surface, reads the relevant references, and states explicitly which layer the cause lives on rather than proposing a surface fix for a structure problem. ## Quick Start Use the ux-evaluation skill to audit this product interface and tell me which layer the main problem actually lives on.
