Lucian UX/UI

Lucian UX/UI Prompt is a library of interactive UI elements. Each element is one self-contained snippet: a <style> block scoped to .uNNN, a root <div class="ux uNNN">, and a <script>. Every element reads its colors from --ux-* theme tokens. The library keeps growing (400 elements now, thousands later), so never assume what it contains. Search it every time.

All access goes through the bundled CLI. It caches on disk and falls back to a GitHub mirror when lucianlabs.dev is unreachable. <skill-dir> is the folder that contains this SKILL.md:

shCopy code
node <skill-dir>/scripts/lucian-uxui.mjs <command>

Add --lang ko for Korean copy. The default is --lang en. Use --out <path> with get or tokens to write files instead of printing them.

Workflow

1. Read the project. Find the framework (React, Next, Vue, Svelte, Astro, plain HTML), the styling approach (CSS modules, Tailwind, global CSS), the theming approach (data-theme, a .dark class, CSS variables) and the language of the site's copy. If there is no project yet, use what the user asked for. If they named nothing, use plain HTML, CSS and JS.
2. Break the request into UI parts, for example: header nav, hero call-to-action button, monthly/yearly pricing toggle, sign-up form, FAQ, success toast, empty state. You build the page layout and sections (hero, pricing grid, footer) yourself. Lucian supplies the interactive parts inside them.
3. Search once per part. If the user names specific elements by number or gallery link (#055, 55, lucianlabs.dev/uxui-prompt/#055), skip the search for them and get those exact elements. English keywords match best, and Korean also works. Read the one-line summaries and pick the element whose behavior fits the part. Prefer a Lucian element whenever a reasonable match exists, rather than writing your own. Build from scratch only when nothing fits, and match the Lucian look with the same tokens.
4. Fetch what you picked: get <ids>, at most a few at a time. Also run tokens once per project.
5. Port each element following references/porting.md. Read it before your first port.
6. Check both themes, a narrow mobile width (375px), keyboard use and prefers-reduced-motion.
7. Report. End your reply with a list of the elements you used. Give one line per element in the form #ID title: where it is used, what you adapted, https://lucianlabs.dev/uxui-prompt/#ID, and then list anything you could not check.

Language

Use the language of the site's copy: --lang ko for a Korean site and --lang en for everything else. When the language is unclear, use English. Element text is sample copy either way. Replace it with the project's real content.

Rules

• Use only code returned by get. Never invent element IDs or reconstruct an element from memory or from its summary.
• Keep the first line of each element, the <!-- Lucian UX/UI Prompt #ID · MIT License ... --> comment, at the top of the component file you create from it. The license requires it.
• Do not dump the whole catalog into context or download every element. Use search, and use list --category to browse.
• Port an element's structure, shapes and motion values (durations, curves, delays) as they are. Adapt the framework, data and colors, not the design.

When the CLI cannot run

• Network blocked (exit code 3, common in sandboxes such as Codex): the CLI needs HTTPS access to lucianlabs.dev or, as a fallback, raw.githubusercontent.com. Request network permission for the command and rerun it. If the network stays unavailable and nothing is cached, tell the user. Do not substitute invented elements.
• No Node.js: use curl with the same data:

  shCopy code
  curl -fsSL https://lucianlabs.dev/uxui-prompt/api/v1/en/catalog.tsv | grep -i "toggle"   # columns: id, cat, category, title, tags, shape, hash, summary
  curl -fsSL https://lucianlabs.dev/uxui-prompt/api/v1/en/e/056.txt                      # one element
  curl -fsSL https://lucianlabs.dev/uxui-prompt/api/v1/en/tokens.css                     # tokens
