Skill

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.

Picking The Right Library

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.

How to use this

  1. Identify the task, not the library the user named. “I need to show a dropdown” is a UI-primitives task (base-ui), even if they asked about something else.
  2. Check what’s already installed. Look at 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.
  3. Recommend one library, state what it’s for in one sentence, and install/wire it up if that’s part of the request. Don’t present a menu of options when the list has a clear answer.
  4. If the task isn’t covered by the list, say so explicitly and recommend from your own knowledge — but be clear you’ve left the curated list.

The list

UI components & primitives

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 Levadialkit is an alternative

Motion & visuals

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.

Charts

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.

Interaction & performance

Task Library
Drag and drop dnd kit
Virtualization (long lists, large tables) Virtuoso

State & styling

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.
