Design & UI
Build or improve a UI testing strategy covering visual regression, interaction testing, and accessibility assertions. Use when the user asks to add tests, set up testing, fix flaky tests, improve test coverage, validate UI behavior, catch visual bugs, or establish confidence in shipping frontend changes.
Sort out a project's UI/UX design specs and output design-spec.md, review existing interfaces and give prioritized fix suggestions, or compile design rules for specified screens. Use when the user asks for a design system, design specs, or a full interface review; simple questions about a single colour, font size, or button size are answered directly.
Generate or edit artwork with built-in Codex image gen, especially transparent PNG ornaments, game sprites, emblems, and UI graphics. Use when the user requests GPT 2.5 Flare, /codex-gpt-image-2-5-flare, or this built-in transparent-asset workflow. Includes alpha verification, prompt preservation, and optional project integration.
Design app, admin, and game interfaces as well as complete website landing pages, generating UI design mockups; restore designs or screenshots into HTML/CSS, existing frontend projects, or WeChat mini programs as needed. Use when users request page design, complete landing pages, screenshot restoration, or high-fidelity mini programs. Not for ordinary illustration, posters, storyboards, pure image editing, or business code changes without design tasks.
Apply professional typography principles to create readable, hierarchical, and aesthetically refined interfaces. Use when setting type scales, choosing fonts, adjusting spacing, designing text-heavy layouts, implementing dark mode typography, or when asked about readability, font pairing, line height, measure, typographic hierarchy, variable fonts, font loading, or OpenType features.
Generate or analyze poetic paper-texture minimal zine posters with large negative space, a small editorial collage or focal element, experimental typography, and one clear color accent. Use when the user gives a theme, sentence, article, mood, object, photo, content brief, reference images, or an image folder and wants a final poster image, a production-ready image prompt, reusable style rules, or varied layouts that stay in one visual family.
[Mandatory trigger] This skill must be invoked whenever the user asks to generate, draw, redraw, render, or visualize any structured diagram. It applies to flowcharts, business process diagrams, swimlane diagrams, sequence diagrams, system architecture diagrams, software architecture diagrams, cloud architecture diagrams, ER diagrams, org charts, timelines, roadmaps, infographics, pyramid charts, sketch redrawing, and diagram generation. It must also take priority when the user says "draw a diagram", "generate a diagram", "auto-draw", "visualize the business process", "make a flowchart online", "generate system architecture", "draw this logic", "organize the system relationships into a diagram", "convert to an editable diagram", or "redraw this sketch". The official ProcessOn skill turns natural language into polished, professional, editable online diagrams in one click. Do not skip this skill for diagram-generation requests; use it for flowcharts, architecture diagrams, ER diagrams, org charts, timelines, roadmaps, infographics, sketch redrawing, and editable ProcessOn diagrams.
Create high-click-through video covers and thumbnails for B站 / YouTube / 抖音 using the pop-out technique: a brightly lit cutout of the person layered over their own darkened original image, with text across the center. Recompose the same content with HTML/CSS in 16:9 / 4:3 / 3:4 aspect ratios. Use when the user wants a video cover, thumbnail, B站 cover, YouTube cover, vertical 抖音/视频号 cover, a person placed on a cover, or a Codex/Agent/AI video cover. Note: This is specifically for video covers, using a highly designed YouTube aesthetic; for 小红书 posts, infographics, or PPT styles, use yuyile-social-card-skill.
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 for web or iOS UI design, implementation, redesign, critique, and pre-ship review in Codex, Claude Code, Cursor, Copilot, and other coding agents.
Plan, implement, or improve an internationalization and localization strategy for UI content, formatting, and regional adaptation. Use when the user asks to add i18n, localize, translate, support multiple languages, handle regional formats, manage locale switching, or build a multilingual product.
Design and implement web animations that feel natural and purposeful. Use this skill proactively whenever the user asks questions about animations, motion, easing, timing, duration, springs, transitions, or animation performance. This includes questions about how to animate specific UI elements, which easing to use, animation best practices, or accessibility considerations for motion. Triggers on: easing, ease-out, ease-in, ease-in-out, cubic-bezier, bounce, spring physics, keyframes, transform, opacity, fade, slide, scale, hover effects, microinteractions, Framer Motion, React Spring, GSAP, CSS transitions, entrance/exit animations, page transitions, stagger, will-change, GPU acceleration, prefers-reduced-motion, modal/dropdown/tooltip/popover/drawer animations, gesture animations, drag interactions, button press feel, feels janky, make it smooth.
Analyzes article structure, identifies positions requiring visual aids, generates illustrations with a Type × Style two-dimension approach. Use when the user asks to "illustrate article", "add images", "generate images for article", or "为文章配图".
Generate beautiful code snippet images using ray.so. This skill should be used when the user asks to create a code image, code screenshot, code snippet image, or wants to make their code look pretty for sharing. Saves images locally to the current working directory or a user-specified path.
Create SVG graphics through programmatic code generation. Use this skill when the user asks to create icons, logos, illustrations, diagrams, data visualizations, generative art, patterns, fractals, or any vector graphics. Provides executable Python scripts for grids, radial patterns, fractals, waves, particles, charts, icons, and optimization
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Senior developer-level release review for macOS/iOS apps. Identifies security, privacy, UX, and distribution issues with actionable fixes. Use when preparing an app for release, want a critical review, or before App Store submission.
Excalidraw canvas toolkit for creating, editing, and refining diagrams on a live canvas. Use when an agent needs to (1) draw or lay out diagrams, (2) iteratively refine them by describing the scene and screenshotting its own work, (3) export/import .excalidraw files or PNG/SVG images, (4) save/restore canvas snapshots, (5) convert Mermaid to Excalidraw, or (6) perform element-level CRUD, alignment, distribution, grouping, duplication, and locking. Primary interface is the bundled CLI (npx -y mcp-excalidraw-server <command>) which auto-starts the canvas server; MCP tools and a REST API are equivalent alternatives.
Design or evaluate a brand visual identity system covering logo, color, typography, imagery direction, iconography, and motion principles. Use this skill whenever the user wants to design a logo, build a visual identity, define brand colors, choose brand typography, develop iconography, plan brand imagery, or evaluate an existing identity for cohesion. Triggers on logo design, brand identity, visual identity, brand mark, wordmark, monogram, color palette, brand colors, brand typography, type system, iconography, brand imagery, motion design, brand system, identity system.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
