Example settingswhat each example above was built from

examples/nami-ramenhero.json

Brand: Nami Ramen
Headline: Slurp loudly

What you get

A one-page hero and a paste-in embed with your name, words and links
A film that loops forever with no visible restart, checked frame against frame
A tall cut of the film for phones, so the subject fills a portrait screen
Zen Old Mincho and Karla in this hero's own colors, with words that rise in once as the page opens
A poster frame for reduced motion and while the film loads, so it is never blank
Checks at 390, 768, 1280 and 1920 px: 14 px minimum text, a headline nothing touches, 44 px tap targets, no overflow
A 1080p MP4 and a 1080x1920 phone MP4, rendered frame by frame
Open-source licenses for every part it builds on

Good fit

Restaurants, ramen bars and food delivery open on steam curling off a rich bowl of ramen in warm light.
A dark panel on the left with a heavy Zen Old Mincho headline, numbered links and the opening facts.
On a phone the bowl fills the top of the screen and the panel becomes a sheet with the menu button.

Not for

Your own video: the layout and colours are set for this film (steam rising and curling from a bowl of ramen with a soft egg)
Changing the colors, fonts or layout through settings (every word and link is yours; the look is fixed)
Long headlines: two short lines, with limits the build enforces
Sound: browsers only autoplay muted video, and the film is silent
Full landing pages below the hero (see the Landing Pages series)

About this skill

A full-screen website hero on five seconds of generated film that loops with no seam: steam rising and curling from a bowl of ramen with a soft egg, chashu and nori on a dark wooden counter in warm light. It uses a side-column layout: a frosted panel the full height of the screen with the wordmark, numbered links, a two-line headline, the introduction, the buttons and short facts, with the film beside it. Wide screens get the wide film and phones a tall cut framed on the subject, so a phone never shows a letterbox or an empty half; every text is at least 14 px and nothing touches the headline. Your agent writes one hero.json with your words and links; the build checks every length, a check at four widths enforces the layout rules and the seamless loop, and a recorder makes 1080p and phone MP4s. It suits a restaurant, ramen bar, food delivery, recipe, kitchenware or any warm, appetising food brand.

Example request

How it works

You ask
Make a Ramen Steam hero for our noodle delivery app: 'Hot, / fast', an order button, two facts, and record it.
Your agent
1. 1
  Collect the words
  Every number, price and claim must come from the person.
2. 2
  Write hero.json
  Copy <skill>/examples/nami-ramen/hero.json (Nami Ramen, ramen counter, open late) and replace every value.
3. 3
  Build
  It lists every problem at once (a missing field, words too long for their place, a bad link) and writes nothing until they're fixed.
4. 4
  Check
  It opens the page at 390, 768, 1280 and 1920 px wide and with reduced motion, and fails on: script errors, sideways scrolling, any text under 14 px, a headline smaller than 6.5% of the screen or that anything else touches, a headline closer than 24 px under the bar, overlaps, text that spills out, links without an address, buttons shorter than 44 px on a phone, a hero that doesn't fill the screen, and a film whose last frame doesn't match its first.
5. 5
  Look at it
  Open the address it prints, and narrow the window to see the phone layout and the tall film.
6. 6
  Record the video (optional)
  Writes out/preview.mp4 (1920×1080, 30 fps, one loop) and out/poster.png; with --tall, out/preview-tall.mp4 and out/poster-tall.png as a phone shows it (1080×1920).
7. 7
  Put it on the site
  Use out/index.html as the page, or paste out/embed.html into an existing page and copy out/assets/ next to it (or change the assets/ paths).
You get
- out/preview.mp4
- out/poster.png
- out/preview-tall.mp4
- out/poster-tall.png
- out/index.html
- out/embed.html

What you need

Node.js 18 or newer. Nothing to install.
Chrome, Chromium or Edge, for the checks and the video (the scripts find it; set CHROME_PATH if they don't).
ffmpeg for the loop check and the video (brew install ffmpeg, winget install ffmpeg, apt install ffmpeg; or set FFMPEG_PATH).
Internet access when the page is opened, for the Google Fonts. Without them system fonts stand in.

Last checked Nov 2, 2026: the package’s own build and render commands ran and passed.

If something goes wrong

The page shows a still picture instead of the film
Reduced motion is on in the system settings (that is on purpose), or the browser blocked autoplay in power-saving mode. The still is the film's first frame, so the hero still looks finished.
A phone shows the wide film cropped badly
The page decides by shape, not width: anything taller than 4:5 gets the tall film. Check that assets/film-tall.mp4 was copied with the page.
The build says a field is too long
Shorten the words. The headline lines are sized for the lengths in template/fields.json.

FAQ

Does the steam jump when the film loops?

No. Steam has no fixed shape and the end is cross-faded into the start, so the loop point can't be seen.

Can I show my own dish?

Not through settings: the film is part of the design. Every word, fact and link is yours.

What should go in the facts?

Short real details such as seats, opening hours or the broth's simmer time, from the person.

Which agents is Ramen Steam Hero written for?

Any agent that reads SKILL.md folders, including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

Do I own what I make with it?

Yes. Everything your agent makes with this skill is yours, including for client and commercial work.

What if it doesn’t work for me?

Email support@lookbk.dev within 7 days of buying and we’ll fix it or refund you.
