Makes a Capacitor iOS app work in windows that resize while running (iPad Split View, Slide Over, Stage Manager, windowed apps, the foldable iPhone). Audits the web layer (viewport, `100vh`, device sniffing, `screen.width`, `window.orientation`, cached safe-area insets) and native code in the app and node_modules plugins (`UIScreen.main`, `interfaceOrientation`, `userInterfaceIdiom`, `keyWindow`, AppDelegate lifecycle, hard-coded bar heights), then applies trait-, window- and scene-based replacements. Checks Info.plist `UIRequiresFullScreen` (ignored on iOS 27, TN3192), iPad orientations, launch screen (ITMS-90870) and the UIScene lifecycle (Capacitor 8.5+). Use for "support iPad multitasking", "Stage Manager layout broken", "app does not resize", "foldable iPhone", or a plugin overlay mis-sized in split view. Do not use for notch padding only (safe-area-handling) or the SceneDelegate migration (capacitor-uiscene-migration).
Build a premium cinematic landing page with mouse-scrub video hero and brand-driven narrative-arc sections. Use whenever the user provides a hero video plus a product / subject / brand and wants a landing page, promo site, product showcase, marketing page, or storytelling site. Works for any language (RTL or LTR — Hebrew, English, Arabic, Spanish, French, Japanese, etc.) and any subject (food, tech, animals, fashion, services, SaaS, wildlife campaigns, music releases, books, real estate). The signature effect is mouse-driven video scrubbing — the hero video lives across the entire page as a fixed backdrop, and moving the mouse left-right scrubs the video timeline so the subject responds to the cursor. Below the hero, 4-5 fully-opaque sections each carry their own brand identity (color, typography emphasis, layout pattern) and walk the viewer through a narrative arc (e.g. longing → joy → nostalgia → contemplation → action). Triggers on phrases like "build a landing page from this video", "cinematic landing page", "mouse scrub hero", "video that follows the cursor", "Apple-style premium product page", "the baby video scrub thing", "narrative landing page", "scrubable hero", "golden landing template", "make a promo site for this brand", "build me a showcase page with this clip". Do NOT use for parallax frame-scrub landings where the page itself doesn't scroll (use `parallax-landing-page` instead) or for video editing / captioning workflows (use `video-edit`).
Submit a packaged .codex-theme file or a linked theme showcase (skin) to CodexThemes through the authenticated codexthemes.ai submit API. Use when a user asks to submit, publish, upload, or share a Codex theme on codexthemes.ai, shares a URL of a theme to list in the directory, asks to configure or check a CodexThemes API key, or has an exported .codex-theme package ready for submission.
Applies data visualization and information design principles to encode data truthfully and efficiently. Use when the question is about charts or graphs — chart type selection (bar, line, scatter, heatmap, small multiples), data-ink ratio and chartjunk reduction (Tufte VDQI), preattentive attributes (Knaflic Storytelling with Data), dashboard layout and KPI design (Few Information Dashboard Design), truthful encoding and chart lie detection (Cairo How Charts Lie), marks and channels (Munzner), colorblind-safe palette selection for charts, or chart accessibility. Not for: brand or UI color palette generation (use core color mode); overall page composition and visual hierarchy (use core audit mode); data-display tables as a UI pattern (use usability); typeface or font selection (use core fonts mode); UI copy or writing (use content-design).
Run a structured UX critique on a screenshot, URL, or HTML snippet - a 0-4 score, up to 6 prioritized issues each with Before/After/Why, and one citation per claim. Given two or more variants, compares them on shared dimensions and names a winner. Given a screen plus a decision question, answers the question with the screen as evidence instead of returning a critique. Trigger phrases - "review this design", "critique this screen", "what's wrong with this UI", "score this design", "which of these two is better", "did the redesign improve this", "should I use a modal or a drawer". Do not use for WCAG-only accessibility audits (use accessibility-audit) or turning a mockup into a dev spec (use design-handoff).
Convert draw.io diagram files (.drawio, .dio, .xml) to high-resolution PNG images. Use when users ask to "convert drawio to png", "export drawio diagrams", "generate png from drawio", "drawio导出png", "转换drawio图片", "生成高清drawio图片", or need to convert draw.io files to image format for documentation, presentations, or publishing.
Run a design system multi-point inspection — assess a design system across 10 stations (coverage, best practices, accessibility, shared language, testing, orchestration, governance, feedback, machine-readable docs, agent access) and produce a red/yellow/green inspection report with a prioritized work order. Use when the user asks to inspect, assess, audit, or health-check their design system, run the inspection or a specific station, or asks "why is my design system's check engine light on?"
Guide for using the Microsoft Fluent UI Blazor component library (Microsoft.FluentUI.AspNetCore.Components NuGet package) in Blazor applications. Use when the user is building a Blazor app with Fluent UI components, setting up the library, using FluentButton, FluentDataGrid, FluentDialog, FluentToast, FluentNavMenu, FluentTextField, FluentSelect, FluentAutocomplete, FluentDesignTheme, or any component prefixed with “Fluent.” Also use when troubleshooting missing providers, JS interop issues, or theming.

Use when user asks to: create a form, build a survey, make a questionnaire, create an onboarding flow, build a feedback form, or any multi-step data collection UI. Outputs standalone HTML files with embedded CSS/JS that can be deployed anywhere.
Generate multiple original brand campaign worlds from a supplied visual reference while controlling how close the new work feels without copying protected signature elements. Use when a user provides a brand identity image, poster, editorial campaign, moodboard, or generated concept and asks for inspired alternatives, several distinct brands in one visual family, a closer-to-reference V2, exact wordmarks inside images, or originality-safe image-generation prompts and outputs

Includes structures, copy, design, CTAs, social proof, and technical optimization.
Light on-demand engineering skill · frontend design: turn a vague "make it look good" into runnable React/Tailwind/shadcn code + design decision notes — with a visual signature element, self-consistent style (consistent design tokens), scenario fit (academic poster/data dashboard/admin back office/mobile/marketing landing each have different information density), anti-"obviously AI" (purple-blue gradients/Inter/16px radii/giant hero/centered stacking/emoji headings), and visual accessibility (WCAG 2.2). When to use: competition entries/project demos/research system interfaces that need a web page or app UI / reworking an existing frontend / choosing a design system, palette or font / building dashboard, admin, landing or mobile UI. Trigger words: frontend / interface / UI / web page / website / design a page / landing page / landing / dashboard / data dashboard / admin back office / admin / component / React / Vue / Tailwind / shadcn / palette / font / design system / design system / make it look good / frontend design / redesign the interface / redesign. Core discipline: never decide the design direction/tech stack/palette/font for the user — these are decision points; give recommendations + reasons + alternatives and stop to ask the user via AskUserQuestion. Zero local design library: look up inspiration/trends/stack versions online (Awwwards / `npm view` / the WCAG site), mark last_checked, mark unknown if not found, never rely on a stale local library. Deliver runnable code, not empty talk; reuse `_shared/visual_qa` to judge contrast (do not reinvent the WCAG math). Not a DAG node (on demand: produces no findings, does not block the main line).

Use when the user asks for animal feature abstraction, mascot logo design, paw/head/antler/tusk/alien/crescent-style symbol ideas, mascot-derived brand marks, direct mascot logo image generation, or revisions to an existing mascot-symbol concept.
