What problem does it solve? Design agents often produce interfaces that are functionally correct but emotionally flat — cold onboarding, generic brand voice, afterthought empty states. This Skill routes any task involving the felt quality of an interface to the right aesthetics principle so design decisions about beauty, tone, and persuasion are grounded in established research. ## Core Features & Use Cases - Principle Routing: Maps design tasks to 22 aesthetics principles grouped by perceived quality, personality and tone, persuasion, and evolutionary biases. - Scenario Heuristics: Provides read-first guidance for common tasks like marketing landing pages, brand voice selection, mascot design, premium tier marketing, and onboarding tone. - Cross-Plugin Pointers: Directs users to sibling plugins for visual hierarchy, learnability, interaction behavior, and accessibility concerns. - Use Case: When asked to make a hero section feel more premium, the router points to the veblen-effect and aesthetic-usability-effect principles rather than generic styling advice. ## Quick Start Ask the agent how a landing page hero section should feel for a premium brand and which design principles apply.
