What it does

Pick UI Library is an agent skill from vvedantb/eva. 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.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. The repository describes itself as: Orchestrate sandboxed agents that run in the cloud while you work. The licence is MIT.

When your agent uses it

  • Frontend & Design work in your project

Example prompts

  • “/pick-ui-library”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  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…
  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…
  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…
  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.

What it can do on your machine

Read from SKILL.md and the folder at commit a5a4df2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • base-ui.com
    • cmdk.paco.me
    • sonner.emilkowal.ski
    • input-otp.rodz.dev
    • joshpuckett.me
    • motion.dev
    • number-flow.barvian.me
    • torph.lochie.me
    • cobe.vercel.app
    • shiki.style
    • recharts.org
    • dndkit.com
    • virtuoso.dev
    • zustand.docs.pmnd.rs

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pick UI Library loads about 1.1k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 476 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

Unstyled, accessible UI components (dialogs, popovers, menus, selects…)base-ui
Command menus (⌘K palettes)cmdk

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.

State & styling

Constructing className strings conditionallyclsx
Type-safe, variant-driven styling for Tailwindcva
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).
