Design & UI
Add moments of joy, personality, and surprise through success states, empty states, loading moments, hover details, and celebratory polish once the fundamentals already work. Use when the user wants delight, charm, personality, or memorable micro-interactions—not when the main need is baseline cleanup or stronger visual impact.
Guided multi-page redesign of an existing website through a four-phase pipeline — extract (crawl and capture the current site), direct (set a visual direction), prototype (generate redesigned HTML), and migrate (emit a deployable static site). Tracks progress incrementally per page in stardust/state.json so redesigns are resumable. Delegates the per-page design craft (typography, spacing, color, layout, motion) to the impeccable skill. Use when the user wants to redesign, revamp, modernize, or restyle an existing site they can point to by URL, run the extract/direct/prototype/migrate flow, or resume a multi-page redesign or migration. Also routes the same-design migration flow (replica) and the donor-design flow (reskin). Not for designing a brand-new site from scratch or one-off single-component edits.
Iterative UI/UX polishing workflow for web applications. Use when improving visual polish, refining desktop and mobile UX separately, running iterative enhancement cycles, applying design patterns like glassmorphism or bento grids, or auditing accessibility and WCAG compliance. Use for Stripe-level visual quality, responsive optimization, and design system alignment.
Generate production-ready, accessible, token-driven component code for ANY framework (React+Tailwind, Next.js, SwiftUI, Vue, Svelte, Angular, Solid, Web Components/Lit, React Native, Flutter, Jetpack Compose, vanilla CSS, or CSS-in-JS). Use when the user wants working UI code for a component or screen in a specific stack
Create standout, technically ambitious interfaces that feel extraordinary through cinematic transitions, advanced motion, heavy rendering, or other high-ambition implementation work. Use when the user wants to wow, impress, go all-out, or push a feature beyond conventional UI polish—not when simple visual confidence or routine cleanup is enough.
Extract reusable components, product patterns, and design tokens into a clearer design system with shared APIs, documented defaults, and better reuse. Use when the user wants to refactor repeated UI, consolidate buttons/cards/forms/sections, build a component library, or turn one-off values into reusable tokens.
Activate this skill when analyzing iOS app UI/UX, evaluating iOS design patterns, proposing iOS interface improvements, or creating iOS implementation specifications. Provides deep expertise in Apple Human Interface Guidelines, SwiftUI patterns, native iOS components, accessibility standards, and iOS-specific interaction paradigms.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Generates article cover images with 5 dimensions (type, palette, rendering, text, mood) combining 9 color palettes and 6 rendering styles. Supports cinematic (2.35:1), widescreen (16:9), and square (1:1) aspects. Use when user asks to "generate cover image", "create article cover", or "make cover".
Use when a developer wants to build or validate Block Kit layouts for Slack messages, modals, or Home tabs: message layouts, modals/forms/dialogs, Home tab interfaces, interactive buttons or menus, or modifying existing Block Kit JSON. Also trigger on any Slack UI component (sections, actions, inputs, headers, alerts, tables, carousels), the words “blocks” or “Block Kit Builder,” a request to preview rendered blocks, or pasted JSON like “type”: “section”. Validates via the blocks.validate API method.
Design a UI component spec to the house quality bar (anatomy, variants, sizes, the 8 states, token mapping, and accessibility). Use when the user wants to design or document a component (button, input, tabs, toast, combobox, date picker, modal, etc.) at the spec level before or alongside code. For generating framework code, use design-code
Design 3D-printable parts as Python functions with nurb. Use when the user wants a part designed, changed, or checked for 3D printing (a bracket, mount, holder, enclosure, shelf, or any STL/STEP to print), and in any directory with a parts/ folder. The user describes the part and judges it in a browser; you model it.
Generate publication-quality AI illustrations for academic papers using Gemini image generation. Creates architecture diagrams and method illustrations with a Claude-supervised iterative refinement loop. Use when the user says "生成图表", "画架构图", "AI绘图", "paper illustration", "generate diagram", or needs visual figures for papers.
Reconstructs reference images into high-fidelity, editable Draw.io files with rendered previews: native Draw.io elements carry text and structure, SVG covers simple icons that match the reference, and cropped or transparent PNGs preserve complex visuals. Use when the user wants a diagram image, research figure, architecture diagram, slide, UI screenshot, or image folder turned into `.drawio` XML; batch requests use a manifest with bounded parallelism when available and a full-fidelity serial fallback otherwise.
Creates comprehensive frontend UI/UX designs including user interfaces, design systems, component libraries, responsive layouts, and accessibility implementations. Produces wireframes, mockups, design specifications, and implementation guidelines. Use when designing user interfaces, creating design systems, building component libraries, implementing responsive designs, ensuring accessibility compliance, or when users mention UI design, UX design, interface design, design systems, user experience, or frontend design patterns.
Reduce visual intensity, saturation, and noise while preserving hierarchy and character. Use when the structure is basically sound but the design feels too loud, bold, garish, aggressive, or overstimulating—not when the real problem is structural clutter, too many features, or not enough personality
Write or review UI copy (buttons, errors, empty states, microcopy, notifications, labels) using the voice & tone system (clear, concise, useful, human, honest) with the what→why→how error formula and inclusive-language rules. Use when the user needs interface copy, error messages, empty-state text, or a copy review
Tells your agent what Mobbin can and can't do and how the Mobbin skills work together, so it picks the right one or says when Mobbin isn't the right tool. Read it first, before any other Mobbin skill or tools, when the user asks about Mobbin or its connection, or starts a design task Mobbin could help with, including one that's too big or outside what Mobbin does
Set up or run design QA gates for token + hardcoded-value lint, automated a11y (axe), contrast, visual regression across variants/states/themes/RTL, and the manual a11y checklist. Use when the user wants CI quality gates, to prevent design regressions, or to QA a component/screen before shipping
Converts Markdown to styled HTML with WeChat-compatible themes. Supports code highlighting, math, PlantUML, footnotes, alerts, and infographics. Use when user asks for "markdown to html", "convert md to html", "md转html", or needs styled HTML output from markdown.
Render a proposed redesign of a page on the current website as a self-contained static HTML file, then iterate via the impeccable craft loop. Per-page, idempotent, stale-aware. Use when the user asks for a redesign prototype, a before/after comparison, a design preview, a page mockup, a visual diff of the redesign, or invokes `$stardust prototype` (`/stardust:prototype` in Claude Code).
Routing-first skill for web accessibility remediation and verification. Use when the main job is classifying which accessibility surface is failing — semantics, keyboard/focus, labels/announcements, visual perception/reflow, media alternatives, or routed-app navigation feedback — and turning vague audit, WCAG, axe/Lighthouse, or "make this accessible" requests into one concrete remediation packet. Broad UI critique for hierarchy, polish, and launch readiness belongs here too. Route component API architecture and system governance to `design-system`, and responsive layout strategy to `responsive-design`.
Set up and use the PrimeVue UI component library in Vue/Vite projects with auto-import, theming, and component configuration. Use when working with PrimeVue components, setting up PrimeVue in a Vue project, configuring themes (Aura, Lara, etc.), or implementing auto-import for PrimeVue components.
Use when the user has built or changed something visual — a UI, an animation, a game, a generated video — and wants it verified, or asks “why does my UI look wrong”, “check that the fix actually worked”, or “does the animation glitch”. Record the running product, critique the recording against plain-language pass criteria, and iterate until it passes with before/after proof.
Command-line interface for Mermaid Live Editor - Create, edit, and render Mermaid diagrams via stateful project files and mermaid.ink renderer URLs. Designed for AI agents and power users who need to generate flowcharts, sequence diagrams, and other visualizations without a GUI.
Adapt a React Native or Expo app to iPhone Duo, Apple's first foldable iPhone — asymmetric safe area insets, resize handling, and how to expose the iOS 27.1 reserved-region and hinge APIs through a native module. Use when a React Native, Expo or JS-based iOS app needs foldable iPhone support.
Generate a complete, accessible brand design system from a brief, as primitive → semantic → component DTCG tokens (color, type, spacing, radius, shadow, motion), light + dark, plus a single theme.css, verified for WCAG. Use when the user wants a from-scratch brand/design foundation, a new palette + type system, or a themeable token kit for a product
