What problem does it solve? Frontend interfaces often end up templated, broken on mobile, or indistinguishable from framework defaults. This Skill provides a structured design process that starts at 375px, enforces accessibility and craft quality floors, and adapts deliberately to Angular, React, or Blazor conventions. ## Core Features & Use Cases - Mobile-First Design Process: Frame the brief, choose a mode (Persuade, Operate, Read, Experience), design at 375px, then scale up through content-driven breakpoints. - Framework-Specific Guidance: Dedicated references for Angular, React, and Blazor conventions, plus Bootstrap vs Tailwind CSS framework selection and token mapping. - Quality Enforcement: A craft floor checklist covering contrast (WCAG AA), touch targets, typography, motion, states, and banned anti-patterns, with commands like shape, layout, typeset, colorize, adapt, audit, harden, onboard, and polish. - Use Case: A developer building a game catalog dashboard in Angular asks for a redesign; the Skill plans the mobile layout first, defines design tokens, applies Angular Material overrides, and audits accessibility before shipping. ## Quick Start Ask the assistant to design a mobile-first responsive landing page for your Angular app using the design skill.
