Design & UI
Implement and configure Syncfusion RadialSlider control in Windows Forms - a circular slider for visual numeric value selection with rotating needle. Use when creating circular value selection controls, rotary inputs, dial-based controls, or radial numeric input. Covers circular value selection, rotating needle control, dial-based input, visual value picker with divisions, and radial numeric input controls.
Implement Syncfusion WinForms SplashControl to display splash screens during application startup. Use this when building startup screens, loading screens, timed splash displays, or animated splash images in WinForms. Covers SplashControl setup, image configuration, timing, animation, and positioning.
Implement Syncfusion SplitContainerAdv control for creating resizable panel layouts separated by a splitter in Windows Forms applications. Use this when building split-view interfaces, multi-pane layouts, or resizable container controls. Covers panel orientation and sizing, splitter appearance customization, container styling, splitter movement events, horizontal/vertical layouts, panel collapsing, and nested containers.
Implement and configure the Syncfusion TrackBarEx control in Windows Forms applications. Use this skill when you need to create interactive value sliders, customize button and slider appearance, manage value ranges, set orientation, and handle scroll events in WinForms projects.
Use this skill to gate iOS SwiftUI design and UX with a pass/fail adversarial review — a single blind reviewer subagent judges screens, diffs, or features against 56 decidable HIG-derived rules, working backwards from mandatory rendered evidence, simulator screenshots (light, dark, accessibility text size) and interaction recordings tiled into filmstrips. Covers navigation/IA (tab bars, five tabs max, system Back), modality and flow grammar (sheets, alerts, unsaved-content protection), layout (44pt targets, safe areas, Dynamic Type), color and contrast, typography floors, Liquid Glass, feedback states (empty, loading, error, launch), motion — filmstrip-primary except the spring-curve and Reduce Motion checks, so code alone never prescribes an unseen animation, and gratuitous decoration fails — plus haptics and craft. Fixes must be the minimal change, removal preferred over addition. Trigger before merging user-facing SwiftUI work. Verdicts only, never fixes; targets without a SwiftUI UI surface abort.
Use when the user needs website design references — whether they describe a style or mood, name reference sites, want brands visually similar to an existing site, or ask for a website without an established visual direction (e.g. "build a website for my bakery"). Finds real websites from a curated library to inform design decisions before building.
Circle reveal (falling droplet + crest-glow liquid-glass) when switching dark/light mode — a switch toggle, an overlay radiating from the CURSOR POSITION (clamped to the button's bounds), a neutral market-style dark-mode palette (GitHub Dark/Vercel/Linear), accepted with real Playwright. Call when the user says 'make dark mode', 'theme toggle', 'switch light and dark', 'circle reveal', 'UI switching effect', or /dark-mode-maker. DIFFERENT from docs-site-macos (that is a macOS documentation site template; dark-mode-maker is a toggle module usable on ANY HTML page).
Internal prototype QA helper. Use only after a Product Design prototype, URL-to-code build, or image-to-code build has a source visual target and a rendered implementation to compare before handoff. Do not use for broad UX critique, design critique, product audits, or flow reviews; route those user-facing requests to audit.
Design how one feature or screen in an iOS app behaves while it works: loading, showing saved data while refreshing, success, empty, error and retry, with the motion, haptics and words for each state, backed by real shipped apps. Use when asked to add or improve loading states, success or error feedback, empty states, retry flows, or "what should happen while this loads". SwiftUI and UIKit, iOS only.
Design, update, and refactor Home Assistant Lovelace dashboards (YAML views/partials) with a constrained, machine-safe design system: button-card-first structure, minimal card-mod styling, optional flex-horseshoe + mini-graph telemetry, strict grid/vertical-stack layout rules, centralized templates, deterministic ordering, and config validation. Use for Home Assistant dashboard work (especially config/dashboards/**), when refactoring views, adding infra/home/energy/environment panels, or translating Stitch design inspiration into safe Lovelace YAML.
Generate spec-reliable App Store screenshots from deterministic HTML/CSS panels, with optional AI-generated sticker assets and style grading. Use when the user wants App Store / store listing screenshots, marketing panels with device frames, screenshot localization or translation ("translate my screenshots"), or asks about Apple screenshot sizes and specs. Not for general image generation, social graphics, or capturing in-app screenshots from a simulator.
Senior landing page designer specializing in high-converting pages for SaaS, apps, and services. Use when building landing pages, hero sections, pricing pages, or any conversion-focused marketing page. Always researches current best practices via Perplexity before designing. Includes AI slop detection and cleaning.
Design, redesign, review, or implement user interfaces using Google Material Design 3 (M3), Material You, and optional Material 3 Expressive principles. Use for UI/UX screens, app flows, design systems, component selection, theming, responsive/adaptive layouts, accessibility audits, Figma-ready specifications, or developer handoff where Material Design 3 is required.
Build an iOS interaction by copying one that already shipped. Use when asked to design or implement any animation, transition, gesture or micro-interaction in SwiftUI: a bottom sheet, a pull-to-refresh, a card morph, an onboarding sequence, a loading state, a success moment. Also use when asked "how does app X do Y" about mobile motion, or for a reference clip to copy. iOS and SwiftUI only.
Design for people with vestibular disorders, motion sensitivity, or seizure conditions. Use when designing animations, transitions, parallax scrolling, video backgrounds, carousels, or any moving content. Triggers on: motion, animation, vestibular, motion sickness, dizzy, nausea, parallax, autoplay, flashing, seizure, prefers-reduced-motion, spinning, scrolljacking.
Give an iOS app one consistent motion language: a small set of named timings, springs and haptics in a single Motion.swift, derived from the app's own code and from real shipped apps with the same feel. Use when asked to make an app's animations consistent, create motion tokens or a motion system, clean up scattered animation values, or define how the app should move. SwiftUI, iOS only.
Use when the user explicitly asks to "generate an NSFC schematic diagram/mechanism diagram/schematic diagram/mechanism diagram" or needs to turn the research mechanism, algorithm architecture, or module relationships from a proposal into a "editable + embeddable in documents" diagram. By default it outputs editable source files (`.drawio`) and rendered files (`.pdf`/`.svg`/`.png`); when the user proactively mentions the Nano Banana image model, it can switch to PNG-only mode and is compatible with Gemini and OpenAI `gpt-image-2`. ⚠️ Not applicable: the user only wants to polish body text (should directly rewrite the text), only wants to change the format/size of an existing image (should use an image processing skill), or has no clear "schematic/mechanism diagram" intent.
Styles Rails views with RoleModel's Optics design system — its components, `--op-` design tokens, and theme overrides. Use when writing or reviewing CSS, styling a view or component, picking a color, spacing, font, radius, or shadow value, fixing hard-coded CSS values, adding a project token, or theming an app (brand colors, fonts, color scales, dark mode). Also use when the user says things like "style this", "make this look like the design", "what token should I use", "fix the hard-coded colors", "change the brand color", or "add dark mode".
Design the theme and component-style architecture of a Panda CSS project. Use when setting up theming, adding brand colors, wiring dark mode or a color-mode toggle, shipping more than one theme with theme.themes, staticCss.themes, data-panda-theme or injectTheme, naming or restructuring design tokens, deciding what belongs in tokens vs semanticTokens vs textStyles vs a recipe, designing a component's variant API, or deciding whether something should be a css() call, a cva, a config recipe, or a slot recipe, including converting a recipe into a slot recipe. Also use when tokens or recipes have grown messy and need a cleanup plan. Do not use for writing styles against a system that already exists (use panda-css), or for upgrading v1 to v2 (use panda-css-migrate).
Generate leftover PlantUML types Mermaid cannot do easily (Salt wireframes, use case, timing, ArchiMate, nwdiag, WBS) and convert them to PNG/SVG. Use when asked for a wireframe, PlantUML image export, extract puml from markdown, or prepare Confluence uploads. Class, ER, state, sequence, and C4 default to design-doc-mermaid on GitHub wiki.
Screenshot-to-HTML prototype generator with iterative refinement and learning memory. Use this skill whenever the user provides a screenshot, mockup, wireframe, or image of any UI and wants it reproduced as a working HTML prototype — or when they want to modify an existing prototype they previously generated. Also triggers on: "照这个做原型", "参考这个图", "把这个页面画出来", "this UI needs to be prototyped", "replicate this design", "convert this mockup to HTML", "帮我出个原型", "根据截图输出 HTML", or any image attachment combined with requests like "输出 HTML", "做成页面", "帮我实现". Even if the user just sends a screenshot with a brief instruction like "加一个字段" or "这个也一样", this skill applies — it means they want you to modify or replicate the UI shown. When in doubt, if there's a UI screenshot in the conversation, use this skill.
Bloom and glow effects using Three.js UnrealBloomPass with React Three Fiber. Use when implementing glow, bloom, luminance-based effects, selective bloom on specific meshes, or neon/ethereal lighting. Essential for cyberpunk aesthetics, energy effects, magic spells, and UI glow.
Audit UI/UX in a SENIOR style — four sections: accessibility · visual-hierarchy · consistency · antipattern, each giving a SCORE/10 + MOST SEVERE ISSUE + HOW TO FIX, then a conclusion of PASS-to-next-step or NEEDS-FIXING. The MEASURABLE part (WCAG contrast, tap-target, geometric overlap/misalignment, missing-label) runs deterministically through the visual-qa engine (headless, 0-token, NO LLM); the part needing EYES (hierarchy, design-system drift, dark-pattern) is an LLM audit. Call when the user says "qc uiux", "audit ui", "inspect the interface", "clean up UI antipatterns", "/qc-uiux", or AFTER there is a mockup/UI. MIRRORS /qc-code (expensive = manual LLM, cheap = automatic deterministic tests). DIFFERENT from /redesign (aesthetic renewal) and /visual-qa (screenshot + pixel guarding) — qc-uiux is a 4-section senior verdict.
Use for any in-page content edit on a WordPress site with a page builder. Covers finding elements, applying surgical edits, duplicating before large changes, and verifying the result. Works across Elementor 3 + 4, Divi 4 + 5, Beaver Builder, Bricks, Oxygen Classic, Oxygen 6, Breakdance, WPBakery, Uncode, and Gutenberg.
Check design-system health for a React+Vite app — raw hex, undefined/unused tokens, scale gaps, DESIGN.md drift, and (opt-in) property→token-family misuse. Use for 'is my design system healthy', 'find raw colors', 'check tokens', or a mixed design system.
Build slide decks and presentations for research talks. Use this for making PowerPoint slides, conference presentations, seminar talks, research presentations, thesis defense slides, or any scientific talk. Provides slide structure, design templates, timing guidance, and visual validation. Works with PowerPoint and LaTeX Beamer.
