Makes a product film (landing-page loop, launch video, promo, demo reel) in code with Remotion, reusing the product's own design system, components and voice. It interviews the user first, then writes the story, syncs scenes to music beats, reviews stills in loops and verifies the final render.

Guides building small always-on WebGL visuals (avatars, ambient orbs, glass and iridescent surfaces) inside product UI: one shared context, a single capped frame loop, cheap fragment shaders, context-loss handling, a mandatory non-WebGL fallback, and React SSR and Server Components pitfalls.

Implements page and route transitions in the Next.js App Router and fixes Framer Motion exit animations that never fire on navigation, using template.tsx with a pathname-keyed AnimatePresence and FrozenRouter, or the View Transitions API via next-view-transitions.

Integrates Lottie and dotLottie animations from After Effects into web, iOS, Android and React Native: playback and segment control, scroll- or hover-driven interactivity, runtime theming and recoloring, plus an After Effects export checklist.

Adds functional UI micro-interactions with Framer Motion (motion/react) and modern CSS: hover and press feedback, toggles, toasts, drawers, modals, list reorder and shared-element transitions, with 100-250ms timings, asymmetric enter and exit easing, and reduced-motion support.

Audits Motion (Framer Motion) code against AnimatePresence rules: wrapping conditional exits, exit props and keys, the useIsPresent and usePresence hooks, choosing a mode, and coordinating nested exits. Reports findings as file:line. For React projects.

Guides the agent in building SVG icon components that morph between any two icons by moving lines instead of crossfading. Every icon uses exactly three lines, unused ones collapse to the center, and grouped variants rotate with springs. Examples use React and Motion and respect reduced motion.

Audits animation code for the right timing function: springs for gestures and interruptible motion, easing for system-driven state changes, linear for progress, and no animation for high-frequency interactions. Also checks spring parameters and durations. Reports file:line findings.

Fixes hover and click dead zones between spaced interactive elements such as chart bars, list rows, tabs and nav items by making hit targets flush and moving visual spacing inside each item, with React and Tailwind examples.

Turns Paper designs (via Paper MCP, Viewfinder or exported JSX) into componentized React/Next.js code: maps hierarchy and reusable components first, one component per icon, tokens in globals.css, shadcn reuse, real fonts and data-driven charts.

Builds product launch, promo and feature announcement videos with Remotion (React): asks nine questions about product, audience, duration, voiceover and channel, proposes 2-3 visual directions, writes a storyboard.json, then codes scenes and optional voiceover.

Prototyper UI's animation conventions for writing, reviewing or debugging component motion: copy-paste class strings for overlays, dialogs and sheets, press-feedback scales, state transitions, easing tokens and prefers-reduced-motion handling.

Guides building Prototyper UI components from scratch when no Base UI primitive exists: ARIA contract first, then keyboard navigation, focus management, controlled and uncontrolled state, form integration and animation, wrapping headless libraries where they fit.

End-to-end guide for adding components to the Prototyper UI library: templates for wrapping Base UI primitives with CVA variants and compound sub-components, plus registry entries, examples and MDX documentation pages.

Usage guide for the Prototyper UI component library, built on @base-ui/react and Tailwind CSS v4 with copy-paste distribution, OKLCH colors and CVA variants: setup, theme tokens, component selection and patterns, noting render= replaces Radix asChild.
