Design & UI
Audit the brand, UX, and site design of leading sites in a vertical as a set of observable cross-site patterns, producing the experience bar a new build must meet or beat. Use this skill whenever the user wants to assess the competitive design field, capture vertical conventions, identify the design and UX bar of a category, or set the experience standard before a build. Triggers on competitor experience audit, UX audit, site design audit, brand audit, design conventions, what makes these sites good, vertical conventions, storefront patterns, merchandising patterns, layout density, primary task, design bar, category conventions, retail vs marketing register, what does the field do. Also triggers when an audit of the competitive field has captured technical signals (SEO, accessibility) but never named the brand, UX, or design conventions, and the build downstream will read as off-vertical without that bar.
Fast, accurate, and comprehensive multiline text measurement and layout library for JavaScript/TypeScript — without DOM reflow. Use when the user needs to calculate paragraph heights, line counts, manual line layouts (text flowing around floated images), or rich text rendering (emoji, CJK, RTL) on DOM, Canvas, or SVG targets. Covers npm install, core API (prepare/layout, prepareWithSegments/layoutWithLines), and options (whiteSpace, wordBreak, letterSpacing). Triggers on: pretext, text measurement, text layout, paragraph height, line layout, text reflow, canvas text measurement, DOM reflow
Creates and authors slide deck presentations using the PromptSlide framework (Vite + React 19 + Tailwind v4 + Framer Motion). Use when the user wants to create a new slide deck, add or edit slides, customize themes or branding, work with slide animations and transitions, capture slides as images, or visually verify slide appearance. Triggers on mentions of slides, decks, presentations, PromptSlide, slide screenshots, or slide-related tasks.
Add a custom in-app product tour (spotlight onboarding overlay) without a library (no joyride/intro.js/driver.js). Draw a dark layer with spotlight cutouts around elements selected by CSS selector, attach labeled tooltips, and place a “tap to close” pill in the largest empty space. Responsive on mobile and desktop, locks scrolling, measures with getBoundingClientRect, and closes on any click. Use when the user wants to “add a tour guide,” “onboarding tour,” “in-app guide,” “spotlight tour,” “product tour,” “walkthrough,” “bonbon-style tour,” or invokes /tour-guide. Suited to React/Next.js + Tailwind. Each route defines its own list of stops (spots); elements are marked with a stable data-tour attribute.
Build or repair a typography system: a modular type scale, font choices and loading, hierarchy, line-height/line-length, and fluid sizing—delivered as tokens (Tailwind fontSize config or CSS variables) applied to real components. Use when the user says “the text looks off”, “fonts are inconsistent”, “headings don't stand out”, “pick fonts for me”, “it's hard to read”, “too many font sizes”, or when an audit finds font-size sprawl. Chooses the scale ratio based on product density (dense app vs. marketing vs. editorial), verifies contrast and measure, and produces type tokens plus a migration map from existing rogue sizes.
An advanced data visualization and layout designer from 甲子渡口. Transforms text, tables, or web pages into visually comfortable Xiaohongshu cards or WeChat Official Account images with an exceptionally retro aesthetic. Features include portrait, landscape, or illustrated layouts; careful control of whitespace, line height, font contrast, and colors; purely static layouts; and automatically adding hand-drawn SVG decorations to balance large areas of whitespace. Use when the user asks to “generate cards,” requests “premium retro text-and-image layout,” or mentions layout options.
Full three-perspective audit of an existing website from one URL — design (tensions + concrete improvement opportunities), SEO/technical, and LLM/AI-search visibility — plus Core Web Vitals, synthesized into a scored, evidence-bound report. Use when the user asks to “audit this site”, “site audit”, “design audit”, “SEO audit”, “why is my site underperforming”, “LLM visibility”, “how does my site look to AI”, or invokes `$stardust audit` (`/stardust:audit` in Claude Code) <url>
Complete guide to React and Next.js best practices covering performance optimization, component architecture, shadcn/ui patterns, Motion animations, and modern React 19+ patterns. Use when writing, reviewing, or refactoring React/Next.js code. Triggers on tasks involving React components, Next.js pages, data fetching, UI components, animations, or code quality improvements. Scope is client-side React/Next — for Node/Express/API backend, use backend-patterns; for cross-cutting TS/JS standards, coding-standards.
Create polished shieldcn README badges, badge groups, charts, headers, sponsors grids, and full README hero sections. Use when a user wants shadcn/ui-styled badges, Shields.io replacement, npm/GitHub/CI/status badges, download charts, README header banners, contributor/sponsor images, or README Studio guidance. Triggers include "add badges", "add shields", "README badges", "npm badge", "GitHub stars badge", "CI badge", "download chart", "README header", "README banner", "contributors grid", "sponsors grid", "build a README", "README Studio", "shieldcn", and requests to make a project README look better.
Expert patterns for scaling mobile games to desktop including mouse/keyboard controls, increased resolution and graphical fidelity, expanded UI layouts, settings menus, window management, and platform-specific features. Use when creating desktop ports or cross-platform releases. Trigger keywords: mouse_controls, keyboard_shortcuts, resolution_scaling, graphics_settings, fullscreen_toggle, window_modes, Steam_integration, desktop_optimization.
An editorial-style poster—newsprint paper, dateline, oversized serif headline with a struck-through word and italic accent, a 2-column body block, and 6 numbered sections with annotated pull-quote captions. Reads like a Sunday-paper full-page essay or a thoughtful launch poster. Use when the brief asks for "magazine poster", "editorial poster", "newsprint", "essay layout", or "manifesto".
Professional UI design system — the visual quality gate for all HTML output. MUST USE together with project-builder when building any HTML page, dashboard, landing page, portfolio, or web application. project-builder handles engineering workflow; this skill handles visual design decisions (color palette, typography, layout, animation). Ensures every generated UI looks professional, modern, and unique — never generic AI slop.
Build terminal user interface (TUI) applications with the Textual framework. Use when creating new Textual apps, adding screens/widgets, styling with TCSS, handling events and reactivity, testing TUI apps, or any task involving "textual", "TUI", or terminal-based Python applications.
Create cinematic movie poster concepts and final poster images from a user's brief, existing video plan, storyboard, character design, or project context. Use this skill whenever the user asks to generate a film poster, movie poster, key art, campaign poster, teaser poster, title poster, or promotional visual for a video project. This skill proposes several creative directions first when appropriate, defaults to a 3:4 poster ratio when no ratio is specified, and ensures typography, title treatment, imagery, genre, setting, and story tone are coherent and visually inventive.
For users creating a two-player co-op game menu or opening animation. Users provide two player names, a game title, a target visual style, and optional character reference images. The Skill locks identity cues, generates an approval image from a fixed menu framework with coordinated color, buttons, icons, and typography, then uses the approved result to rebuild the character, UI-copy, and event timing instructions for the final video. It outputs a co-op game intro featuring two characters, player cards, and menu interaction motion. Best for game concepts, character-led menus, and social content; not for playable game development, complex multi-page UI, exact brand-logo replication, or generic character-free title sequences.
Not an accessibility surveyor's opinion and not legal advice. Implement Israeli web accessibility compliance per IS 5568 standard, which is WCAG 2.0 AA plus Israeli national changes, for Hebrew RTL applications. Use when the user asks about Israeli accessibility law, "negishot" (accessibility), IS 5568, "teken negishot" (accessibility standard), "nachim" (disabilities), Hebrew screen reader support, RTL ARIA patterns, or accessibility audits for Israeli websites. Covers mandatory legal requirements under the Equal Rights for Persons with Disabilities Act, who is exempt, enforcement and penalties, the accessibility coordinator role, Hebrew screen reader compatibility (NVDA, JAWS, VoiceOver), native mobile apps, and RTL-specific ARIA patterns. Do NOT use for general WCAG guidance without Israeli context (use standard a11y resources instead), or for building a self-hosted accessibility preferences widget (use wcag-accessibility-widget).
Build customer journey maps and service blueprints that visualize the end-to-end user experience including touchpoints, emotions, friction, and underlying systems. Use this skill whenever the user wants to map a customer journey, build a service blueprint, identify friction across an experience, align teams on the user experience, or visualize touchpoints and pain points. Triggers on customer journey, journey map, service blueprint, user journey, experience map, touchpoint analysis, friction map, journey audit, end-to-end experience, customer experience map. Also triggers when the team has departmental views of users but no shared map of what the experience actually feels like.
Use when a project needs its product vision (what it is, why it exists, what it refuses to become), written to docs/ux/vision.md with an alignment rule. Triggers: "vision" / "видение", "product vision" / "продуктовое видение", "define product direction". Not for personas or jobs (ux-foundation).
Use for Blossom Carousel React or Next.js installation, stylesheet setup, JSX examples, Tailwind examples, accessibility or a11y guidance, navigation controls (BlossomPrev, BlossomNext, BlossomDots, BlossomDot), command events, overscroll events, and React-specific integration.
Read a Canva design and return structured, actionable design feedback — visual hierarchy, copy/messaging, layout and spacing, consistency, readability, and accessibility. Read-only; makes no changes to the design. Use when the user asks to “review my design,” “give me feedback on this,” “critique my deck/poster/flyer,” “how can I improve this design,” or “what's wrong with this slide.”
Designing build-your-own product configurators (Tesla-style, custom-pricing, plan-builders) with constraint logic, real-time pricing, validation, and save-and-share mechanics. Honest about infinite-options (decision paralysis), canned-bundles-only (no real customization), and guided-configuration (smart defaults plus meaningful constraints plus escape hatches) patterns. Triggers on configurator design, build-your-own, custom configuration, plan builder, product customizer, configuration tool. Also triggers when users abandon mid-configuration, when configurator conversion is poor, or when a configurator is being scoped for the first time.
Same-design migration—re-platform a site to AEM Edge Delivery (or any clean front end) keeping its current design near pixel-perfect. Recreates key pages (one archetype per page type) as clean re-authored HTML/CSS (never DOM copies), verifies each against the live site with a measured source-fidelity gate (structural + visual + stitched pixel diff per breakpoint), then hands off to migrate/deploy/rollout for site-wide delivery (subsumes prepare-migration's prep cascade—never chain the two). The only permitted design changes are entries in an explicit inconsistency register. Use when the user says “migrate this site keeping its current design”, “same-design migration”, “pixel-perfect replatform to AEM”, or “keep the design, change the platform”. NOT for redesigns—those are the stardust core pipeline (direct/prototype) or uplift.
A three-card social-media carousel laid out as 1080×1080 squares — three cinematic, on-brand panels with display headlines that connect across the series ("onwards." → "to the next one." → "looking ahead."). Each card has a brand mark, a number / total, a caption, and a "loop" affordance. Use when the brief asks for a "carousel post", "social carousel", "Instagram carousel", "LinkedIn series", "X thread cards", or "三连发".
Apply a Korean brand's published DESIGN.md from the ko-design-md catalog (getdesign.kr) — colors, typography, spacing, radius, components, do's & don'ts — to the UI you are building in the CURRENT project. Use this skill whenever the user wants UI built or restyled in the *style of* a catalogued Korean service — "토스 디자인으로 만들어줘", "당근 스타일로 이 화면 다시 꾸며줘", "getdesign 카탈로그에서 배민 디자인 가져와서 적용", "KRDS 톤으로 폼 잡아줘", "make this look like Toss". Works in any repository over the network. Do NOT use it to add or edit catalog entries (that is the separate `design-md` producer skill), to explain the DESIGN.md format itself — there is no UI to restyle there — or to build a quiz or exam page that only borrows a brand's tone.
Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices". Focuses on visual design and interaction patterns. Do NOT use for performance audits (use core-web-vitals), SEO (use seo), or comprehensive site audits (use web-quality-audit).
Apple Human Interface Guidelines reference, updated for iPhone Duo and OS 27. Provides authoritative platform-specific design rules, component specifications, exact measurements, and interaction patterns for iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. Use when designing, reviewing, auditing, or fixing any Apple platform UI, or when asked about specific HIG components, sizing, system behaviors, frameworks (HealthKit, SiriKit, ARKit, etc.), or platform conventions. Also use when the user is designing any digital interface and could benefit from established design principles, even without an explicit Apple platform context. Includes a guided /duo workflow that adapts an existing iOS app to iPhone Duo, plus opt-in enforce mode with independent review
Apply a Classic Easter seasonal overlay: pastel Theme/StyleBox injection, confetti/shimmer VFX, elastic juice, mesh surface_override painting, cursor/audio swaps, and a date-window activation gate with player opt-out. Use when shipping holiday skins, April events, or egg-hunt juice without mutating shared .mesh/.tres assets. Keywords: pastel, seasonal Theme, StyleBox, confetti, Easter egg, surface_override, TRANS_ELASTIC, Disable Seasonal Themes, activation gate.
Google Fonts typography system generator. Suggests single fonts (strict mode) and font pairs (contrast mode) with complete typographic scales following Tailwind Typography rhythm concepts. Generates CSS custom properties, Tailwind config, and embed links. Trigger: "choose a font", "font pairing", "typography system", "type scale", "Google Font", "heading font", "body font", "web font", "font for my site", "typographic scale", "font suggestion", "which font", "font recommendation", "serif or sans".
When the user wants to optimize, improve, or increase conversions on any marketing page — including homepage, landing pages, pricing pages, feature pages, or blog posts. Also use when the user says "CRO," "conversion rate optimization," "this page isn't converting," "improve conversions," or "why isn't this page working." For signup/registration flows, see signup-flow-cro. For post-signup activation, see onboarding-cro. For forms outside of signup, see form-cro. For popups/modals, see popup-cro.
Turn a user’s script into a minimalist, tech-inspired, Jobs-style vertical HTML presentation in one click. Trigger this skill when the user wants to generate a PPT, presentation, Slides, or slideshow, or requests a tech, minimalist, or Jobs-style presentation. The output is a single runnable HTML file.
Run a 5-dimension expert design review on any HTML artifact in the project — Philosophy / Visual hierarchy / Detail / Functionality / Innovation, each scored 0–10. Outputs a single self-contained HTML report with a radar chart, evidence-backed scores, and three lists: Keep / Fix / Quick-wins. Use when the brief asks for a "design review", "design critique", "5 维度评审", "design audit", or "what's wrong with my design".
