Compile a theme, sentence, object, mood, article idea, or photo into a quiet Japanese/Korean zine-style editorial poster — tall aged paper, large negative space, one small image anchor, experimental typography, one high-chroma accent, print/scan defects — then generate the image. Use when asked for a zine poster, a minimal editorial poster, a paper-texture poster, a riso/xerox/letterpress poster, cover art for an essay or newsletter, or a poster "in that quiet Japanese zine style."
Unified poster and standalone image generation skill with hard routing. Produces one or more final poster/image assets as requested, using mandatory HTML-based layout for information-heavy posters and image-first generation only for strictly visual assets.
Revenue-Centric Design (RCD) — evidence-backed principles for making a SaaS or startup product convert, retain, and monetize. Use when the user works on a landing page or CRO ("my page isn't converting"), onboarding/activation ("users sign up but don't stick"), churn/retention ("customers keep canceling"), pricing/monetization ("how should I price this"), checkout/forms ("dropdowns kill conversion", "annotated checkout"), dashboards/data viz ("cognitive load", "KPI shortlists"), positioning/ICP/go-to-market, feature scope, A/B-test rigor, or AI-era differentiation — or asks for the behavioral-science mechanism behind a design choice.

Best-practice guide for authoring a Muxy extension — how it should look and behave so it reads as a native part of the app. Covers theming (follow the theme, never hardcode colors), the sizing scale, and which surface to use. Mechanics (manifest fields, permissions, the window.muxy API) live in the linked docs.
Use for new frontend applications, dashboards, games, creative websites, hero sections, and visually driven UI from scratch, or when the user explicitly asks for a redesign/restyle/modernization. Builds from clean, airy, high-taste, readable image-generated concept design with section-specific references, faithful implementation, and browser testing.
Comprehensive guide for creating professional UI/UX designs in Penpot using MCP tools. Use this skill when: (1) Creating new UI/UX designs for web, mobile, or desktop applications, (2) Building design systems with components and tokens, (3) Designing dashboards, forms, navigation, or landing pages, (4) Applying accessibility standards and best practices, (5) Following platform guidelines (iOS, Android, Material Design), (6) Reviewing or improving existing Penpot designs for usability. Triggers: "design a UI", "create interface", "build layout", "design dashboard", "create form", "design landing page", "make it accessible", "design system", "component library".
Generate ReactFlow diagrams as .rfd.json files using a predefined library of custom node types, edge presets, and layout templates. Use when the user wants to visualize architectures, workflows, data flows, or concepts, or wants to convert analysis of a codebase into a diagram viewable in a ReactFlow-based SPA.
Reverse-engineers a UI animation from a screen recording. Extracts frames with ffmpeg, tracks motion per frame with OpenCV, fits easing and spring curves, annotates choreography (leads, lags, over-stretch), and emits CSS, Motion/Framer Motion, SwiftUI, React Native, or UIKit code plus a handoff motion spec. Use when the user shares or uploads a screen recording or video of a UI animation, or asks to "reverse engineer this animation", "recreate this animation", "match this easing", "extract the animation curve", "figure out the spring from this video", "copy this transition from a video", "how does this animation work", or "reproduce this motion". For designing new motion from scratch or reviewing motion code, use ui-animation instead.
Spencer's house style for UIs. DO NOT INVOKE THIS SKILL UNLESS SPECIFICALLY ASKED. Use whenever Spencer asks for a frontend, page, screen, component, dashboard, app shell, modal, form, table, or any kind of web visual — including phrasings like "build a UI for X", "throw together a screen", "make a dashboard", "I need a quick app". Also use when starting a brand-new React project from scratch on this machine. Overrides any general "frontend-design" skill: Spencer dislikes the default shiny-AI aesthetic and wants tight, neutral, dense, system-font UIs that look like the due-diligence and security-review apps. If Spencer is editing an existing repo with a clearly different stack (e.g. Next.js with shadcn already wired up), follow that repo's conventions, but still apply Spencer's typography, density, and tone preferences from this skill.
Apply storytelling principles to create, review, and improve data visualisations and data-driven communications. Use when the message or story of a data communication (chart, dashboard, infographic, data-driven deck or report) needs structuring or review, or when structuring narrative arcs, hooks, or aha moments in data-driven communications.
Comprehensive guide for implementing the Syncfusion Angular TimePicker component. Use this when working with time selection inputs, time formatting, or timepicker event handling in Angular applications. Covers TimePicker API, styling, methods, and accessibility patterns.

Use this skill whenever the user needs to integrate uView Pro into UniAppX projects, configure UniAppX-specific settings, or handle platform differences.
Design or critique a product's color palette and system — base hue, harmony, neutrals, semantic colors, tonal scales, and tokens. Applies the always-true core and gates context-dependent decisions (dark mode, brand expressiveness, accessibility trade-offs). Trigger when creating a color palette, choosing UI colors, building a color system, setting up color tokens, or reviewing a palette for issues.
Orchestrated, build-from-zero UX workflow. Establishes context once, then composes the generative ladder in order — foundations (color, type, spacing) → components → screens → flows — applying each skill with relevance gating, and hands the result to design-review. Trigger when the user is starting a new product/app/UI from scratch, "help me design an app", "set up a design system and screens", "I'm starting a new product", or any multi-artifact design build — but NOT when they ask for one specific screen or component (let that skill trigger directly).
Use when the user's task involves antdv-next — writing antdv-next components, debugging antdv-next issues, querying antdv-next props/events/slot/tokens/demos, migrating between antdv-next versions, or analyzing antdv-next usage in a project. Triggers on antdv-next-related code, imports from 'antdv-next', or explicit antdv-next questions.
Apply exact Tailwind arbitrary shadow utilities for polished, layered neutral elevation. Use when compact cards, controls, panels, popovers, hero media, feature callouts, or modal-like containers need refined shadows without default Tailwind shadow scales or colored tinting.
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.
Use for \"/build-figma\", a figma.com/design URL with node-id, or \"implement this Figma\" into a web, desktop, or shared UI. Orchestrates Figma MCP intake, maps nodes to the repo's own design system, then a verify-this visual judge. Do not paste Figma Tailwind.
Polish a Flutter app's screens — visual hierarchy, typography, color and contrast, spacing, section clarity. Reads a reference screen first to lock in the app's existing design tone, then drives the running app on an Android emulator via the `android-emulator` skill (screenshots, taps, swipes), makes targeted widget and `ThemeData` edits, and spawns an independent evaluator sub-agent to score design quality, originality, craft, and functionality. Use this skill whenever the user wants to improve, polish, refine, critique, audit, or tighten the visual design of a Flutter screen — even when they don't say "polish" (e.g. "make this look better", "fix the layout on settings", "tighten up the home screen", "this screen feels off", "review the UI", "design pass", "make it less generic", "feels too Material default"). Skip for non-Flutter UIs, feature work, or routing/functionality changes.
Use when Codex is building, revising, or reviewing a frontend UI, web app screen, responsive layout, component surface, dashboard view, form flow, visual system, or no-template product interface that needs visual polish, accessibility, screenshots, or browser QA.
Invoke when the user asks about art style, visual language, style guide, character design, environment art, UI art direction, asset pipeline, reference boards, color palette, or shape language. Triggers on: "art style", "visual", "style guide", "character design", "environment art", "asset pipeline", "color palette", "shape language". Do NOT invoke for UI/UX layout (use game-ux-designer) or creative vision (use game-creative-director). Part of the AlterLab GameForge collection.

Use for Bodymovin/Lottie JSON, dotLottie archives, renderer and player compatibility, fonts and glyphs, image assets, markers and segments, deterministic video capture, responsive sizing, optimization, accessibility, and cross-platform QA; not for general After Effects animation craft or live-action/video delivery.
Creative direction and design intelligence for Remotion motion graphic videos. Use when an agent needs to (1) convert a script or SRT into a shot-by-shot visual design document, (2) ideate motion graphics with editorial intent for each scene, (3) produce a design brief for user approval before writing Remotion code. Always use before generating any Remotion video code from a script.
Build, revise, resize, export, and quality-check editable Point paid-social templates in PowerPoint and Canva-compatible formats. Use for seasonal or campaign social assets that require separate editable copy, logos, benefit rows, legal footers, and illustrations; approved Point brand assets; preview PNGs; transparent illustration exports; or production preflight.
Build cursor-following spotlight reveals that expose a second aligned image through a soft radial mask. Use for hover-to-color, before-and-after, x-ray, material, texture, product-detail, and illustrated hero effects where a desaturated or embossed base image should remain visible while another treatment follows an eased pointer
Tailwind CSS v4 conventions for real projects — CSS-first configuration with @theme, automatic content detection, the v3-to-v4 migration diffs, and dynamic class-name safety. Use when writing Tailwind utilities, setting up or upgrading Tailwind, defining design tokens as Tailwind theme values, debugging classes that do not generate, or when unsure whether a project is on v3 or v4.
Install official tech brand logos from the Elements registry. Use when user needs logos for tech companies (Clerk, Vercel, GitHub, etc.), AI providers (OpenAI, Anthropic, Claude), social platforms, or any brand assets. Triggers on "logo", "brand", "icon for [company]", "add [company] logo", placeholder logo detection, or when building landing pages, auth UIs, or integrations showcases.
Manages Tambo threads, messages, suggestions, voice input, and image attachments. Use when working with conversations, sending messages, implementing AI suggestions, adding voice input, managing multi-thread UIs, or handling image attachments with useTambo, useTamboThreadInput, useTamboSuggestions, or useTamboVoice.
Verify whether a live web app matches its design specification using deterministic CSS checks against the DOM, AND verify user flows by executing Gherkin scenarios via Nova Act. Translates design claims into rules and runs them via verify_* MCP tools; executes flows via act() and act_get(). Produces a combined visual + flow report with annotated screenshots and per-flow detail. Use when checking visual style, component rules, accessibility, project conventions, platform patterns, or end-to-end user journeys against a live site.
Design or critique how a product prevents, surfaces, and recovers from errors — input/validation errors, system & network failures, AI/prediction failures, destructive actions, and 404/dead-end pages. Leads with prevention (most errors are designable away), applies the always-true core (validate without interrupting, write recoverable messages, give a safety net, never dead-end) and gates context-dependent levers (confirm vs. undo, validation timing, humor, degradation, transparency vs. security) with trade-offs. Trigger when the user asks to design or review error states, error messages, form validation, a 404/error page, undo/confirmation flows, failure handling, or graceful degradation.
