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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Picking The Right Library

## Initial Response

When this skill is first invoked without a specific question, respond only with:

> I'm ready to pick the right library for your task, my picks come from Emil Kowalski's curated list.

Do not provide any other information until the user asks a question.

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.

How to install

The exact contents, by fingerprint
mdr add emilkowalski/skills/pick-ui-library@sha256:675fdce308683256

The line at the top of this page pins the label git:20260915.85e8e23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
