Pick the right library for a given frontend task from a curated, opinionated list — numbers, OTP inputs, charts, command menus, virtualization, drag and drop, toasts, state, styling, and more. Only runs when explicitly invoked; it does not trigger on its own.

This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.
Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks "what could be animated here?" or wants to "make this feel more alive". For fixing existing animations, use improve-animations or review-animations instead.
Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to "improve the animations", "audit the motion", "make this app feel better", or wants a roadmap of animation fixes rather than a review of a single diff.
Reviews animation and motion code against a high craft bar derived from Emil Kowalski's design engineering philosophy. Default to flagging; approval is earned.
Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.
Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term ("the bouncy thing when a popover opens" → Pop in; "the iOS rubber-band scroll" → Rubber-banding). Use when the user asks "what's it called when…", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.

A lookup skill. When invoked with a task ("I need toasts", "what should I use for drag and drop?"), match the task to the curated list below and recommend the library. These are deliberate, taste-driven picks — don't substitute alternatives outside this list unless the user asks for one or the task genuinely isn't covered.
package.json first. If the project already uses a listed library, use it. If it uses a competitor (e.g. react-window instead of Virtuoso), flag the recommendation but don't churn the dependency without being asked.| Task | Library |
|---|---|
| Unstyled, accessible UI components (dialogs, popovers, menus, selects…) | base-ui |
| Command menus (⌘K palettes) | cmdk |
| Toasts / notifications | Sonner |
| One-time password / verification code inputs | input-otp |
| Customizable GUIs / control panels | Leva — dialkit is an alternative |
| Task | Library |
|---|---|
| General-purpose animation (springs, layout animations, enter/exit) | motion (Framer Motion) |
| Animating numbers (counters, prices, stats) | NumberFlow |
| Animated text components | torph |
| 3D globes | Cobe |
| Dynamic OG images (HTML/CSS → SVG/PNG) | Satori |
| Syntax highlighting | shiki |
Reach for motion when you need springs, layout animations, exit animations, or gesture-driven values. A simple hover or fade doesn't need it — plain CSS transitions are the right tool there.
| Task | Library |
|---|---|
| Real-time / streaming charts | Liveline |
| General charts (static or interactive dashboards) | recharts |
The split: if data points arrive live and the chart scrolls with time, use Liveline. Everything else is recharts.
| Task | Library |
|---|---|
| Drag and drop | dnd kit |
| Virtualization (long lists, large tables) | Virtuoso |
| Task | Library |
|---|---|
| State management | zustand |
Constructing className strings conditionally | clsx |
| Type-safe, variant-driven styling for Tailwind | cva |
| Theme switching / dark mode (no flash on load) | next-themes |
The styling split: clsx for ad-hoc conditional classes; cva when a component has real variants (size, intent, state) that deserve a typed API. They compose — cva uses clsx-style inputs internally.
<div>-based dropdown/dialog with manual focus handling → base-ui, which handles accessibility, focus trapping, and dismissal.useState-per-component web of props for shared state → zustand.
