Summary
The Pick Ui Library agent skill provides opinionated, curated recommendations for frontend libraries across various tasks like UI components, animation, charts, state management, and styling. This agent skill is invaluable for frontend developers working on web applications who need to quickly choose the right tool for common UI challenges without extensive research. It is a skill with 44K installs, indicating significant adoption within the o-mega.ai registry. It acts as a lookup skill, taking a task description and recommending a specific library from its curated list. The agent is guided to first identify the underlying task, check existing project dependencies, and provide a single, opinionated recommendation, such as `Sonner` for toasts or `dnd kit` for drag and drop. It also advises on common mismatches, like using `base-ui` for accessible dropdowns instead of building manually, or `Virtuoso` for long lists.
Skill Definition
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
- 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.
- Check what's already installed. Look at
package.jsonfirst. 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. - 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.
- 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 | Leva — dialkit 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
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.
Common mismatches to catch
- Toasts built by hand or with a modal library → Sonner exists for exactly this.
- A
<div>-based dropdown/dialog with manual focus handling → base-ui, which handles accessibility, focus trapping, and dismissal. - Animating a number by re-rendering text → NumberFlow handles digit transitions properly.
- Rendering a 1,000+ row list directly → Virtuoso before reaching for pagination hacks.
- A
useState-per-component web of props for shared state → zustand. - Template-literal className ternaries three conditions deep → clsx (or cva if it's variant-shaped).
