Build sophisticated React animations with Motion (formerly Framer Motion) - declarative animations, gestures (drag, hover, tap), scroll effects, spring physics, layout animations, and SVG manipulation. Optimize bundle size with LazyMotion (4.6 KB) or useAnimate mini (2.3 KB). Use when: adding drag-and-drop interactions, creating scroll-triggered animations, implementing modal dialogs with transitions, building carousels with momentum, animating page/route transitions, creating parallax hero sections, implementing accordions with smooth expand/collapse, or optimizing animation bundle sizes. For simple list animations, use auto-animate skill instead (3.28 KB vs 34 KB). Troubleshoot: AnimatePresence exit not working, large list performance issues, Tailwind transition conflicts, Next.js "use client" errors, scrollable container layout issues, or Cloudflare Workers build errors (resolved Dec 2024).
Explain how CE.SDK Web features work — concepts, architecture, and workflows. Covers React, Vue.js, Svelte, Angular, Electron, Vanilla JavaScript, Node.js, Nuxt.js, Next.js, SvelteKit. Use when the user says "explain", "how does X work", "walk me through", "what is", "describe", or wants to understand a CE.SDK concept at a conceptual level for Web development. Generates custom markdown explanations with diagrams and code examples. Not for looking up existing docs (use docs-{framework}), not for writing implementation code (use build). <example> Context: User wants to understand how text layers work user: "Explain how text layers work in CE.SDK" assistant: "I'll use /cesdk:explain to generate a detailed explanation." </example> <example> Context: User needs a concept explained in their context user: "How does the block hierarchy work for video editing?" assistant: "Let me use /cesdk:explain to create a custom explanation for video block hierarchy." </example> <example> Context: User needs to understand a workflow user: "Walk me through the asset loading pipeline" assistant: "I'll use /cesdk:explain to explain the asset pipeline." </example>
Implement real-time Hotwire behavior: Turbo Streams over WebSocket/SSE, custom stream actions, inline stream tags, live list updates, and cross-tab state synchronization. Prefer this skill when the core problem is push-based updates or stream action orchestration. Use hwc-navigation-content for pull-based pagination/tab/lazy-navigation flows, hwc-forms-validation for form lifecycle and validation, hwc-media-content for media upload/playback behavior, hwc-ux-feedback for generic loading/progress/transitions, and hwc-stimulus-fundamentals for non-stream Stimulus fundamentals.
Consistent Tailwind CSS patterns for React/Next.js applications. Use when styling components with Tailwind, adding responsive design, implementing dark mode, or organizing utility classes.
Use when "building React artifacts", "creating HTML artifacts", "bundling React apps", "single HTML file", or asking about "artifact builder", "shadcn components", "Tailwind artifacts"
Build web components using Custom Elements v1 API with Declarative Shadow DOM, attribute-driven state, handleEvent pattern, and zero DOM selection. Use when creating custom elements, extending built-in HTML elements, or implementing component-based architecture. NO querySelector, NO innerHTML, NO external libraries - pure web platform APIs only.
Comprehensive UI/UX design skill for building modern, responsive web applications with Tailwind CSS, shadcn/ui, Material UI, Chakra UI, Ant Design, and Mantine. Use when users need to - (1) Choose a design system for their project, (2) Build responsive layouts and components, (3) Implement forms with validation, (4) Create accessible user interfaces, (5) Design task management UIs (todo apps, dashboards), (6) Apply responsive design patterns, (7) Implement dark mode, or (8) Build component libraries. Triggers include requests like 'design a todo app', 'create responsive layout', 'which UI library should I use', 'implement dark mode', 'build a form with validation', or 'make this mobile-friendly'.
Guide for using Sentry's layout and text primitives. Use when implementing UI components, layouts, or typography. Enforces use of core components over styled components.
Review UI changes against Swiss International Style design system. Checks colors, typography, borders, shadows, spacing, and anti-patterns. Use before committing any frontend UI changes.
Explains the mental model and architecture of the code under `packages/compiler-cli`. You MUST use this skill any time you plan to work with code in `packages/compiler-cli`
Design and build reusable, well-documented components. Master component composition, prop design, variant systems, state management, and documentation. Create a scalable component library that enables consistency and speeds up development. Works with React, TypeScript, and Tailwind CSS.
Actionable design system complementing official frontend-design plugin. The plugin provides philosophy; this skill provides executable patterns. Invoke when: - Building web components, pages, or applications - Designing UI that needs to stand out (not generic) - Implementing visual polish and micro-interactions - Choosing typography, color palettes, or spatial layouts CRITICAL: Avoid "AI slop" aesthetics. Make creative, unexpected choices. MANDATORY: Consult Gemini before any frontend work. See also: references/dna-codes.md, references/banned-patterns.md
