Frontend & UI

pick-ui-library

Matches a frontend task to one curated, opinionated library pick.

What it is

A lookup skill invoked explicitly. It maps a stated task to a single recommended library from a curated table covering primitives, motion, charts, virtualization, state and styling.

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 i
From the upstream SKILL.md

Why it matters for design

  • One recommendation per task, so no menu of options to argue over.
  • Checks package.json first, so it reuses what the project already has.
  • Catches hand-rolled dropdowns and toasts, replacing them with accessible primitives.

What it covers

  • How to use this
  • UI components and primitives
  • Motion and visuals
  • Charts
  • State and styling
  • Common mismatches to catch

How to install

pick-ui-library

  1. Clone the repo.

    git clone https://github.com/emilkowalski/skills
  2. Point Codex at the skill file.

    skills/pick-ui-library/SKILL.md
  3. Then describe the UI you want. Codex follows the skill.

How to run it with Codex

  1. Invoke it explicitly; it never triggers on its own.

  2. State the task, not the library name, such as ‘I need toasts’.

  3. It names one library, explains its use, then wires it up.

Every plugin here is free, open source, and links to its real upstream source.
