Design & UI
Raw mechanical interfaces & tactical telemetry. For visually important web tasks, it must first generate the design image(s) itself, deeply analyze them, then implement the website to match them as closely as possible. In Codex, it must prefer large, readable, section-specific images instead of tiny compressed boards, generate fresh standalone images for sections or detail views instead of cropping old ones, avoid lazy under-generation, avoid cards-inside-cards-inside-cards UI, and keep the hero clean, spacious, readable, and visible on a small laptop.
DEFAULT poster pipeline — build an academic conference poster (ICML/NeurIPS/ICLR/CVPR/...) as a single HTML/CSS file with measurement-driven hard gates, real paper figures, a two-hue design-token system, and print-ready PDF via headless Chromium. Use when the user says "做海报", "poster", "conference poster", "paper poster", or asks to design/redo a research poster. Supersedes the retired LaTeX /paper-poster.
Create HTML dashboards with KPI metric cards, bar/pie/line charts, progress indicators, and data visualizations. Use when users request dashboards, metrics displays, KPI visualizations, data charts, or monitoring interfaces.
Generate interactive HTML presentations with neobrutalism styling, ASCII art decorations, and Agency brand colors. Outputs HTML (interactive with navigation), PNG (individual slides via Playwright), and PDF. References the brand-agency skill for colors and typography. Use for presentations, slide decks, pitch materials, or visual summaries.
Use this skill when users need to apply themes, customize appearance, switch dark mode, use CSS variables, configure icons, or modify visual styling for Syncfusion Angular components. Covers icon library, size modes, and Theme Studio integration.
Puts real design variations of one project file on the user's own localhost, behind a small card that flips them with the arrow keys, then keeps listening for their verdict. Use when the user wants design variations, alternatives, or directions to choose between; asks to try a different hero, layout, palette, section, or page; wants to design something new and compare a few takes; clicked the card (a vary, more, or done ask is queued); or wants to continue or finish a variate session. It works in an empty folder (serves a page, drafts four fresh designs) and in a real project (varies one file in place), on any stack. Not for a single change with one right answer, a refactor, or a non-visual edit: just edit the file for those
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components—not for simple single-file HTML/JSX artifacts.
Create Databricks AI/BI dashboards. Must use when creating, updating, or deploying Lakeview dashboards, as Databricks Dashboard has a unique JSON structure. CRITICAL: You MUST test ALL SQL queries via CLI BEFORE deploying. Follow guidelines strictly.
Frontend visual replication skill. Explores a target website’s publicly visible pages via Playwright MCP or agent-browser, captures screenshots and layout information, then generates a static or client-side frontend replica that approximates the original’s visual appearance and page structure. This skill replicates FRONTEND PRESENTATION ONLY — it does not reproduce backend logic, server-side behavior, databases, or any non-public content. The user is responsible for ensuring they have proper authorization (ownership, license, or explicit permission) before replicating any website. Authorization gate: Before starting, the agent MUST confirm with the user that they have the legal right to replicate the target site. If the user cannot confirm, the skill MUST refuse to proceed.
Draws hand-inked cartoon critters and living objects as SVG cards (480x360), each acting out a coding or design idea. Identified by thick black brush-pen outlines that swell and taper and break into separate strokes, loose marker-and-watercolour fills that slip past the line, diagonal hatching instead of solid shadow, huge googly eyes with two specular dots, and stray ink hairs and flecks, in tomato red, leaf green, sunflower yellow, sky blue and teal on white. Covers palette, brush numbers, mascot construction (eyes, blush, mouths, 3-finger hands), props, ground patches and a tested, seeded brush kit. Use when asked for ink sketch, hand-drawn, brush pen, sketchy, doodle, marker or watercolour-cartoon illustrations, googly-eyed mascots or critters, playful empty states, onboarding, 404 or error pages, loading states, blog headers, feature spots or marketing cards.
Elite mobile app image-generation skill for creating premium, app-native screen concepts and flows. Designed for iOS, Android, and cross-platform mobile products. Prioritizes clean hierarchy, comfortably readable text, strong multi-screen consistency, controlled color palettes, non-generic creative direction, textured surfaces, image-led composition, tasteful custom iconography, and clean phone mockup framing. By default, screens should be shown inside a subtle premium iPhone or similar phone mockup with a visible frame, while the main focus stays on the app content itself. This skill generates images only. It does not write code.
Implements the Syncfusion Angular Rich Text Editor (ejs-richtexteditor) from @syncfusion/ej2-angular-richtexteditor using RichTextEditorModule, HtmlEditorService, and MarkdownEditorService. Use this skill for toolbar configuration, image/video/audio insertion, paste cleanup, AI assistant integration, emoji picker, slash menu, mentions, import/export Word/PDF, form validation, and source code view in Angular applications.
Build a Wix Headless site fast by wiring SHIPPED, verified @wix/sdk code instead of authoring the integration from recipes. Each Wix business vertical ships a typed, framework-agnostic React core (data layer returning plain DTOs, hooks, headless components) plus an Astro overlay (SSR pages with owner-editable SEO pre-wired) and a build-time REST seed script — the agent scaffolds via the Wix CLI, deploys the shipped code, seeds the backend, designs the presentation layer itself on the shipped hooks (product card/grid, PDP, home, theme), and releases to Wix hosting. Works on Wix-managed Astro (ambient auth, the default) and on any React-based project (Vite, non-Astro) over the public OAuth client id. Verticals: stores/storefront (products, categories, variants, cart, hosted checkout), bookings (services, appointment/class time slots, staff, booking form, checkout-or-place), rentals (rooms, vehicles, gear by the hour or the day: resources, customer-picked length, priced quote, checkout), blog (posts, categories/tags, rich content), cms (structured content collections), forms (schema-driven visitor forms: render, validate, submit), events (listing, RSVP, ticket sales), members (login, gated pages, account), portfolio (project collections, media galleries), pricing-plans (plan grid, hosted purchase), restaurants (menus, online ordering, table reservations), faq (categorized questions and answers, search, a link per question), donations (campaign pages, goal progress, one-time and recurring donations via hosted checkout). Triggers: build me a store/blog/booking/rental/event/restaurant/portfolio/FAQ/donation site fast, take appointments fast, rent out rooms/cars/equipment headless, sell tickets or membership plans headless, collect donations headless, wix headless kit, connect a Wix business app with ready-made SDK code.
Draws hand-authored SVG spot illustrations in a halftone line style for design and coding scenes. Identifying traits are a confident black line with a slight hand wobble and contours left open, grey tones made only of fine halftone dots clipped to shapes, a few solid black masses (hair, leaves, a bag, a black tee), warm off-white paper and no colour at all. Covers the two-ink palette, line weights, the open-contour and stipple techniques, a seeded compiler that turns tone tags into dot fills, rubbery long-limbed characters and expressive hands, doodles, floor pools and a render-and-critique loop. Use when someone asks for halftone, stipple, dotted, risograph-like, newsprint, black-and-white, monochrome line, editorial line or zine-style illustrations, or for empty states, onboarding, 404 pages, blog headers, feature spots and marketing cards in that look.
Create and continuously revise an SVG page workspace from page-by-page copy or video-idea-system’s visual-plan.json and assets, producing editable PPTs or fixed-version video frame snapshots. Use for page creation and revision based on source materials or production packages, reuse of visual references, and template extraction for the library requiring human confirmation
Implement and configure the Syncfusion Angular Scheduler (Schedule) component for calendar and event management. Use when building schedulers, calendar systems, event management applications, appointment booking interfaces, or resource scheduling solutions. Covers timeline views, day/week/month views, recurring events, time slot management, and working hours configuration
Implement the responsive tabbed navigation in Angular using Syncfusion Tab. Supports tab selection, dynamic loading, drag-and-drop reordering, localization, multiple orientations, state persistence, data binding, remote data, animations, and advanced patterns like wizards, nested tabs, and collapsible tabs.
Build or audit a design system including component library, design tokens, naming conventions, contribution model, and documentation. Use this skill whenever the user wants to build a design system, audit an existing system, define design tokens at the system level, structure a component library, or set up design system governance. Triggers on design system, component library, design tokens, atomic design, atoms, molecules, organisms, design system documentation, Storybook, Figma library, system governance, design contribution model. Also triggers when teams are inconsistent across products and a system is the answer
Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

Use when creating mobile ports or cross-platform mobile builds. Trigger keywords: TouchScreenButton, virtual_joystick, gesture_detector, InputEventScreenTouch, InputEventScreenDrag, mobile_optimization, battery_saving, adaptive_performance, MOBILE_ENABLED
Use when working on landing pages — creation, copywriting, design, optimization, or conversion rate improvement. Covers hero sections, above-the-fold content, value propositions, CTAs, landing page templates, and high-converting page structure. Applies to sales pages, lead capture pages, product pages, and marketing site pages. Use this skill for landing page copy, landing page design, landing page optimization, CTA writing, conversion rate optimization, hero section content, value proposition work, and any page builder or landing page template tasks.
Use when adding an animated UI component, text effect, cursor/hover effect, or WebGL/canvas background to a React project via React Bits (reactbits.dev) — or when asked to recall/write a React Bits component's code, props, or install steps from memory instead of fetching it.
Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.
Builds, fixes, styles, and composes UI with the Gravity UI design system — the React ecosystem of @gravity-ui/* packages (uikit, charts, table, navigation, date-components, icons, and more). Routes to the correct package when look-alikes exist, applies theming and required setup, and prevents invented component APIs. Applies when working with @gravity-ui imports, uikit, ThemeProvider, --g- CSS tokens, or any prompt (EN or RU) mentioning gravity-ui, гравити, дизайн-система, компоненты, дашборд, таблица, график, or форма.
Implementar e revisar Tailwind CSS com tokens, variantes, responsividade, dark mode, container queries e CSS sustentável. Use quando houver tailwindcss ou utilitários Tailwind em templates; confirme a versão porque configuração e diretivas diferem entre gerações.
Implement, review, and refactor SwiftUI features using the iOS 26+ Liquid Glass API. Use when adopting Liquid Glass in new UI, converting existing surfaces to glass, reviewing glass usage for correctness, or fixing common Liquid Glass pitfalls (custom blur stacks, scroll views, button shapes, bottom bars, pre-enclosed symbols).
Use when creating, reviewing, or styling charts, graphs, dashboards, sparklines, or any data visualization. Applies to Recharts, ECharts, Chart.js, matplotlib, Plotly, seaborn, D3.js, and SVG. Enforces Tufte principles (data-ink ratio, direct labeling, range-frame axes) plus modern screen-first standards (accessibility, responsive, dark mode)
Raw mechanical interfaces fusing Swiss typographic print with military terminal aesthetics. Rigid grids, extreme type scale contrast, utilitarian color, analog degradation effects. For data-heavy dashboards, portfolios, or editorial sites that need to feel like declassified blueprints.
Implement the Syncfusion Angular AI AssistView component. Use this skill when you need to create conversational AI interfaces, integrate AI services, add chat-like UI, or create intelligent assistant applications. Includes setup, configuration, event handling, AI integrations (OpenAI, Gemini, Ollama), speech features, chain-of-thought reasoning, generative UI tool support, and customization. Use this skill for all AI AssistView component implementation needs.
TRIGGER: before putting a UI / screen / component / animation comparison into `AskUserQuestion` `preview:` chips, invoke this skill and ask "quick inline chips, or a real HTML prototype?" — no exception for "simulate", "demo", "mock up". Builds real HTML prototypes for visual design, component playgrounds, animation tuning, and design-system exploration — even when the production target is React, Swift, SwiftUI, or Android. For N alternatives use html-brainstorm-grid; for one tunable component use this skill.
Build a guided requirements-to-implementation workflow for new Power BI reports and dashboards from semantic models, datasets, or PBIP projects. Use when the user wants to: (1) plan then implement a report, (2) define audience, scope, page plan, design direction, dependencies, and delivery target, (3) create a locked report spec with approval before PBIR authoring. For direct edits to existing report files, use `powerbi-report-authoring`. For design-only critique or redesign, use `powerbi-report-design`. Triggers: “build me a dashboard,” “create a new report,” “plan then implement,” “define and build Power BI report,” “walk me through creating a report.”
Apply platform accessibility best practices to SwiftUI, UIKit, and AppKit code. Essential companion to any SwiftUI, UIKit, or AppKit skill — always use together. Use whenever writing, editing, or reviewing ANY SwiftUI views, UIKit view controllers, AppKit views/window controllers, or platform UI — even when the user doesn't mention accessibility. Also use when the user mentions VoiceOver, Voice Control, Dynamic Type, Reduce Motion, screen reader, a11y, WCAG, accessibility audit, Nutrition Labels, accessibilityLabel, UIAccessibility, NSAccessibility, assistive technologies, or Switch Control. Not for server-side Swift, non-UI packages, or CLI tools.
Routing-first reusable component architecture for shared frontend primitives, slots, controlled ownership, alternate-root composition, and docs/verification packets. Use when the user needs to decide what should become a shared primitive, how a component API should expose variants or subcomponents, when parent state should control the component, how to compose a button/link/dialog onto alternate element types, or what Storybook/example coverage is required. Route design-token or cross-product governance to `design-system`, accessibility-heavy remediation to `web-accessibility`, layout adaptation to `responsive-design`, app-level state ownership to `state-management`, and React performance work to `react-best-practices`.
Draws original cosy animal scenes as hand-authored SVG cards (480x360) in a grainy gouache, risograph-like style. Identifying traits are flat shapes with no outlines on a hot-pink card; soft 3-4 stop gradient shading on every rounded form, darker toward edges and base; a fine dark multiply grain that gathers at each shape's edges; a chalky purple-pink shadow pooled under the group; and big glossy eyes with cream star highlights, framed by grained autumn leaves and sparse cream sparkles. It covers design and coding moments with one cute animal at a laptop, monitor, desk, window, mug or book stack. Use when someone asks for grainy, gouache, riso, risograph, textured, cosy, cozy, autumn, hygge, storybook or children's-book style animal art, or for an empty state, onboarding step, 404 page, blog header, feature spot or marketing card with a warm handmade feel.
Draws original hand-written SVG spot illustrations in the One-line style, joyful action figures doing design and coding work. One continuous uniform black line (2.3 px at 480 wide) loops and doubles back to draw the whole figure. Flat coral, periwinkle and white patches sit behind the line, wobbly and deliberately knocked 2–6 px out of register like a misprinted riso. Tops carry coral stripe lines, and there is no ground plane, only a squiggle, a curl or a few speed strokes, all on warm beige paper. Covers the palette, a route-building toolkit (tube limbs, hand and shoe loops, wobble patches, masks), poses, composition and a render-critique loop. Use when asked for one-line, single-line, continuous-line, misregistered, riso-style or playful doodle illustrations, for empty states, onboarding, 404 pages, blog headers, feature spots, launch announcements or marketing cards.
Implement and configure the Syncfusion Angular Gantt Chart component (ejs-gantt, GanttModule). Use when building Angular applications with Gantt chart functionality, task scheduling, dependencies, or resource management. Covers component setup, task dependencies, taskbar editing, critical path analysis, resource allocation, timeline configuration, filtering, sorting, export, undo/redo, state persistence, and localization
