Design & UI
Create and configure the Syncfusion React Menu navigation component for hierarchical menu structures, dropdowns, and context menus. Use this skill whenever the user needs to implement menus, navigation bars, dropdown menus, hamburger menus, mobile menus, sub-menu positioning, menu item interactions, data-binding menus, RTL menu layouts, menu customization with icons/separators, event handling, or advanced features like scrollable menus, persistence, and item state management.
Clarify priority and emphasis by fixing unclear primary actions, competing visual weight, loud section titles, and weak label/value treatment. Use when the user mentions hierarchy, prioritization, too much competition, grayscale confusion, loud headings, or unclear primary actions.
Implement the Syncfusion React Toolbar component to create responsive command bars and action toolbars. This skill covers organizing buttons, separators, and input components with various overflow handling modes. Use this when building rich text editors, document editors, or command-driven interfaces in React applications.
Expert blueprint for UI themes using Theme resources, StyleBoxes, custom fonts, and theme overrides for consistent visual styling. Covers StyleBoxFlat/Texture, theme inheritance, dynamic theme switching, and font variations. Use when implementing consistent UI styling OR supporting multiple themes. Keywords Theme, StyleBox, StyleBoxFlat, add_theme_override, font, theme inheritance, dark mode.
Pick Lucide icons for a concept, UI placement, or vault note. Searches the full Lucide catalog for real, verified icon names. Use when the user says 'what icon for X', 'suggest a Lucide icon', 'pick an icon', or needs an icon for note frontmatter, a button, or a section header.
Extract color palettes from images, websites, or designs. Identifies dominant colors, generates complementary schemes, and exports in multiple formats (HEX, RGB, HSL, Tailwind, CSS variables). Use when users need color schemes from images, brand colors, or design system palettes.
This skill should be used when the user asks to "make an animated illustration", "animate an illustration", "make a generative motion piece" / "动态平面", "turn AI-generated art into something that moves", "make a poetic or ambient motion piece / motion poem", "make a visual metaphor", or "combine AI-generated visuals with code-driven motion". Covers generating isolated illustration assets with AI, compositing them as sprites, frame-accurate deterministic rendering, and the craft of expressive, concept-driven motion. NOT for data charts (use chart-animation), pure text (use kinetic-typography), or 3D/particles (use webgl-animation).
Implement Syncfusion React Sparkline components for compact, inline data visualization. Use this when working with sparklines, mini charts, or trend indicators in constrained spaces. This skill covers all 5 sparkline types (line, column, area, win-loss, pie), tooltips, markers, data labels, range bands, axis customization, and themes. Ideal for displaying data trends within grids, dashboards, or tables without full-sized charts.
Use when the user is designing, prototyping, or rewriting a desktop app that must run on multiple OSes (macOS + Windows, optionally Linux) AND feel indistinguishable from a native app to its users — fast launch, native windowing, native input handling, native materials. Trigger words include "cross-platform desktop", "Electron alternative", "Tauri vs native", "WebView wrapper", "near-native performance", "Raycast architecture", "WebKit/WebView2 quirks", "WKWebView", "system tray app", "global hotkey app", "launcher app". Do NOT trigger this skill for pure web apps, pure mobile apps, or for greenfield projects that have no native-feel requirement.
Review or audit a design/UI across 6 weighted dimensions with Nielsen's 10 heuristics and a prioritized findings table. Use when the user wants a design critique, quality score, heuristic evaluation, or audit of an existing screen, page, or product before/after build.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Build WebGPU visual effects with the Shaders component library (npm `shaders`) in React, Vue, Svelte, Solid or vanilla JS. Use when a user asks for a shader, animated background, gradient, aurora, blur, glass, distortion, noise, particles, glow, transition, cursor effect, or any GPU-rendered visual on a web page, or mentions shaders.com, the Shaders CLI, presets, or the design editor.
Generate images using Google Gemini's image generation capabilities. Use this skill when the user needs to create, generate, or produce images for any purpose including UI mockups, icons, illustrations, diagrams, concept art, placeholder images, or visual representations.
When the user wants to optimize signup, registration, account creation, or trial activation flows. Also use when the user mentions "signup conversions," "registration friction," "signup form optimization," "free trial signup," "reduce signup dropoff," or "account creation flow." For post-signup onboarding, see onboarding-cro. For lead capture forms (not account creation), see form-cro.
Produce platform-correct social media graphics: pick the right dimensions and layout per platform, write the headline/body/CTA copy, build the generation prompt, and generate the image via the repo's FAL.ai pipeline. Use whenever the user wants a social post visual, Instagram post/story/carousel, LinkedIn graphic, Twitter/X image, TikTok thumbnail, Pinterest pin, launch announcement graphic, or 'something to post about X' — even if they never name a platform. Also use to adapt one design across several platforms. Produces a Social Graphic Spec per asset (platform, dimensions, layout, copy, full generation prompt) plus generated images when FAL_API_KEY is available.
Generate and improve accessible alt text for data visualizations and images in R packages and Quarto documents. Use when the user wants to add, improve, or audit alt text for figures in a pkgdown site or .qmd files. Activate for requests that mention fig-alt, fig.alt, figure descriptions, or alt text in the context of an R package or Quarto document.
Build complete transactional email systems: React Email templates, provider integration (Resend, Postmark, SendGrid, AWS SES), preview server, i18n support, dark mode, spam optimization, analytics tracking. Use when adding transactional email to a new product, migrating between email providers, refactoring legacy email templates for accessibility, or adding internationalization to existing templates.
When the user wants to optimize post-signup onboarding, user activation, first-run experience, or time-to-value. Also use when the user mentions "onboarding flow," "activation rate," "user activation," "first-run experience," "empty states," "onboarding checklist," "aha moment," or "new user experience." For signup/registration optimization, see signup-flow-cro. For ongoing email sequences, see email-sequence.
Add analytical chart (chart + table hybrid) to SAP Fiori Elements List Report using aggregated data. Supports CAP and ABAP RAP (OData V4). Use when asked to add a chart section, aggregated data visualization, or Analytical List Page chart to a List Report.
Reduce voluntary and involuntary churn through cancel flow design, save offers, exit surveys, and dunning sequences. Use when designing or optimizing a cancel flow, building save offers, setting up dunning emails, or reducing failed-payment churn. Trigger keywords: cancel flow, churn reduction, save offers, dunning, exit survey, payment recovery, win-back, involuntary churn, failed payments, cancel page. NOT for customer health scoring or expansion revenue — use customer-success-manager for that.
Use this skill when designing terminal user interfaces, creating TUI layouts, choosing TUI color schemes, implementing keyboard navigation, building terminal dashboards, or working with any TUI framework. Activates on mentions of TUI design, terminal UI, Ratatui layout, Ink components, Textual widgets, Bubbletea views, terminal color palette, keybinding design, panel layout, split panes, terminal dashboard, box-drawing characters, sparklines, progress bars, modal dialogs, focus management, or terminal accessibility
Design lens critique covering visual hierarchy, clarity, and anti-slop patterns — produces a findings table, no code edits unless asked. Use when the user wants a design review, says "what's wrong with this UI", or needs a second opinion before a handoff or presentation. Invoke when the user asks for critique on their UI, or mentions 'critique' alongside design / UI / frontend work.
Stop coding agents from shipping generic UI. Use UIZZE's 800,000+ real web and iOS screens to build product-specific interfaces, define a design contract, cover required states, and run a hard finish gate. Use when designing, implementing, redesigning, critiquing, or pre-ship reviewing a web or iOS interface in Codex, Claude Code, Cursor, Copilot, or another coding agent. Trigger with "anti-ui-slop", "stop UI slop", "ground this UI in real screens", or "run the UI finish gate".
Provides design diagnostics, four-direction visual previews, design system compilation, implementation, and visual QA for pages, components, and product interfaces. Also creates and edits WeChat Official Account covers, Bilibili covers, YouTube thumbnails, Xiaolvshu graphics, and Xiaohongshu covers, checking crops and readability for each platform. Use when the user requests a design from scratch, redesign, UI/UX improvements, interface review, design system creation, or a design inspired by a particular style, or asks to create an official account cover, design an official account header image, edit a WeChat article cover, or make a Bilibili cover, YouTube cover, Xiaolvshu graphic, or Xiaohongshu graphic. Do not use for business-logic changes only, copyediting alone, or general coding unrelated to interfaces. By default, the current Codex executes directly; call an external model only when the user explicitly names K3 in the current task.
Reverse-engineer the design taste of any website. Given a URL, captures DOM data and a screenshot via a real browser, then runs a 4-step analysis to produce {domain}.md + {domain}.json with practical design tokens (colors, typography, spacing, radii, shadows, grid) and taste DNA (Trigger → Decision → Reason → Evidence trade-offs explaining WHY the design works). Use whenever the user wants to extract a site's design system, study a competitor's visual language, port an aesthetic to a new project, or generate design guidance for an AI coding agent. Triggers on '/taste <url>', 'analyze the design of X', 'what makes X's site good', 'extract design tokens from X', 'give me X's design DNA', 'build something in the style of X', 'I want my app to feel like X'. Output rejects AI slop ('clean', 'modern', 'user-friendly') in favor of concrete px/hex values and restraint trade-offs. Do NOT use for scraping data, summarizing page content, or tasks unrelated to visual design.
Build a frontend with a deliberate visual direction held through palette, typography, structure, and texture, with on-screen strings that name real information rather than fabricated demo data or filler labels. Use when building or restyling a frontend.
Create professional research posters in LaTeX using beamerposter, tikzposter, or baposter. Support for conference presentations, academic posters, and scientific communication. Includes layout design, color schemes, multi-column formats, figure integration, and poster-specific best practices for visual communication.
When the user wants to create or optimize in-app paywalls, upgrade screens, upsell modals, or feature gates. Also use when the user mentions "paywall," "upgrade screen," "upgrade modal," "upsell," "feature gate," "convert free to paid," "freemium conversion," "trial expiration screen," "limit reached screen," "plan upgrade prompt," or "in-app pricing." Distinct from public pricing pages (see page-cro) — this skill focuses on in-product upgrade moments where the user has already experienced value.
Generates distinctive interfaces that avoid generic AI aesthetics, using extreme typography, cohesive themes (Cyberpunk, Brutalist, Vaporwave, Nordic Minimalism), orchestrated staggered animations, and layered backgrounds. Originally published as Koomook/claude-frontend-skills; installed from a verbatim mirror.
Build guided and interactive virtual tours through a 3D environment with authored camera paths, room and floor-plan navigation, orbit inspection, smooth mode handoffs, and progressive loading. Use for architectural walkthroughs, real-estate tours, museums, showrooms, and explorable spaces built with Three.js or a similar renderer.
Design and redesign EdgeSpark frontends with distinctive, production-grade visual direction instead of generic AI-looking UI. Use when building or polishing landing pages, marketing sites, dashboards, auth flows, portfolios, product surfaces, or reusable frontend sections in EdgeSpark, especially when the task mentions design quality, aesthetics, typography, color, layout, motion, art direction, or making the UI feel more premium and original.
