Create distinctive, bold UI designs that avoid generic AI aesthetics. This skill should be used when users want frontend components with strong visual identity, creative typography, intentional color palettes, and production-grade animations - specifically to avoid the bland, safe, homogeneous "AI slop" that plagues most generated interfaces.
Use when the user needs to build web components, pages, applications, or any Web UI (websites, landing pages, dashboards, React components, HTML/CSS layouts). This Skill generates distinctive, production-grade front-end interfaces, with a focus on high-quality design and avoiding generic AI style.
World-class frontend engineering - React philosophy, performance, accessibility, and production-grade interfacesUse when "frontend, react, vue, svelte, next.js, nuxt, component, state management, redux, zustand, client side, spa, ssr, hydration, bundle size, web vitals, accessibility, a11y, responsive, css, tailwind, frontend, react, typescript, performance, accessibility, components, state, architecture" mentioned.
Audit a game, feature, failure loop, combat encounter, reward system, progression wall, or high-variance mechanic for perceived fairness and frustration. Use when diagnosing whether players feel cheated, whether difficulty feels deserved, whether randomness, feedback, and challenge interact badly, or why a design remains technically functional yet still produces anger, blame, or refusal to retry
Entry skill for HarmonyOS multi-device adaptation. Use when the task broadly concerns HarmonyOS multi-device adaptation, or when the correct scenario is still unclear. This skill classifies the request by phase and scenario type, then routes to one or more scenario files for screen and window size, fold state, avoid areas, interaction methods, natural orientation, or hardware access.

Use when: drag-and-drop, scroll animations, modals, carousels, parallax. Troubleshoot: AnimatePresence exit, list performance, Tailwind conflicts, Next.js "use client".
Build interface motion that would pass a strict review. Decides whether something should animate at all, names its purpose, picks the cheapest tool, the right properties, the curve, the duration or spring, the origin, how it interrupts and how it exits, then writes the implementation with reduced-motion built in. Use when asked to animate, add motion, add a transition, make something feel alive, or when building any component that enters, exits, moves or changes state. For scroll-driven and WebGL work use scroll-and-webgl.
Build premium, consistent App Store screenshot campaigns with Nano Banana. Use when Codex needs to analyze an app codebase for brand, style, and claims, decide which screens should be captured, direct the user to take specific screenshots, turn those screenshots into advertisement-first App Store slides, keep a consistent style anchor across the set, and normalize the final exports to App Store portrait sizes.
Generates NG-ZORRO code and guidance for Angular projects using `ng-zorro-antd`. Covers installation, LESS-variable theming (default, dark, compact, aliyun presets), the experimental dynamic CSS-variable theme, component usage across all categories (general, layout, navigation, data entry, data display, feedback), ReactiveForms / Signal Forms integration via `nz-form`, internationalisation (`provideNzI18n`), accessibility, and the module → standalone migration. Use when the user mentions NG-ZORRO, ng-zorro, ng-zorro-antd, Ant Design for Angular, `nz-*` components, `Nz*Module`, OR when the Angular project's `package.json` contains `ng-zorro-antd`. Pairs with `angular-developer` for Angular fundamentals.
