What you get
- A one-page hero and a paste-in embed with your name, words and links
- The observatory cut out of every frame and drawn over the end of your headline and a giant outline of your word
- The intro tied to the film's own clock: the capitals come into focus letter by letter, the reticle locks onto a star, the log card's bar fills
- Stills for reduced motion, no WebGL, blocked autoplay or a slow connection, so it is never blank
- A phone layout: the headline stays in the frame, the introduction and buttons move into a block underneath
- A 1080p MP4 with the film's sound and a poster, rendered frame by frame
- Checks at 390, 768, 1280 and 1920 px for overflow, overlaps, links and script errors
- Open-source licenses for every part it builds on
Good fit
- Data, analytics, AI and developer tools can open on an observatory under the Milky Way, its red-lit dome turning as the camera closes in.
- Anyone who wants words behind a moving subject gets giant wide capitals that come into focus with the full stop tucked behind the dome.
- Products with a live number to show can fill a glassy observation-log card whose progress bar fills as the film plays.
Not for
- Swapping in your own video: the matte is made for this film, and the scene (an observatory under the Milky Way) is the design
- Changing the colors, fonts or layout through settings (every word and link is yours; the look is fixed)
- Long headlines: the capitals take one word of up to 7 letters and the italic line up to 20 characters
- Sound on the live page (browsers only autoplay muted video; the MP4 keeps the sound)
- Full landing pages below the hero (see the Landing Pages series)
About this skill
A website hero on five seconds of generated footage: a white domed observatory on a desert ridge under the Milky Way, its slit open on a red-lit telescope as the camera pushes in and the dome slowly turns. Giant wide capitals come into focus one letter at a time under a light italic serif line, and the observatory is cut out of every frame and drawn over them, so the full stop tucks behind the dome; a red reticle zooms in and locks onto a star, and a huge outline of the word runs behind the dome. Around it are a reticle wordmark and links, an observatory-red button, a glassy observation-log card with a live dot and a filling bar, and three short facts. Your agent writes one hero.json with your words and links; the build checks every length and writes a page and an embed, and a recorder makes a 1080p MP4 with sound.
Example request
Make a Desert Observatory hero for our analytics product: italic line 'See what changed,', the capitals 'Clearly', our links and trial button, the log card lines, and record the video for our launch post.
How it works
Your agent
- 1
Collect the words
Every number, price and claim must come from the person.
- 2
Write hero.json
Copy
<skill>/examples/farlight/hero.json(Farlight, observability for data pipelines) and replace every value. - 3
Build
It lists every problem at once (a missing field, a word too long for its place, a bad link) and writes nothing until they're fixed.
- 4
Check
It serves the page on localhost and opens it at 390, 768, 1280 and 1920 px wide and with reduced motion.
- 5
Look at it
Open the address it prints.
- 6
Record the video (optional)
Writes
out/preview.mp4(1920×1080, 30 fps, five seconds, with the film's sound) andout/poster.png(the last moment). - 7
Put it on the site
Either use
out/index.htmlas the page, or pasteout/embed.htmlinto an existing page and copyout/assets/next to it (or change the fourassets/paths to where you host them).
- 1
You get
- out/preview.mp4
- out/poster.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_PATHif they don't). - ffmpeg for the video (
brew install ffmpeg,winget install ffmpeg,apt install ffmpeg; or setFFMPEG_PATH). - A web server for the page. Opened straight from disk (
file://) browsers won't let the page draw the film, and it shows the still;node scripts/serve.mjs outserves it on localhost. - Internet access when the page is opened: GSAP and the fonts load from jsDelivr (pinned, with an integrity hash) and Google Fonts. Without GSAP the hero shows its still with every word in place.
Last checked Nov 9, 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
It was opened from disk; run
node scripts/serve.mjs outand open the address. If it still shows the still, the section'sdata-fh-stillattribute says why (reduced-motion,no-webgl,autoplay-blocked,film-failed,film-slow,no-timeline).The film doesn't play on the live site but did locally
The film is on another domain without CORS headers. Serve
assets/from the same site as the page, or addAccess-Control-Allow-Originon the CDN.The build says a field is too long
Shorten the words. The wide capitals are sized for up to 7 characters and the italic line for 20.

Write a reviewFAQ
Can I put my own video behind the headline?
No. The matte that cuts out the observatory was made for this film, so the footage is part of the design. Every word and link is yours through hero.json; the footage, colors, fonts and layout stay as they are.
How long can the headline be?
The italic line takes up to 20 characters and the capitals one word of up to 7 letters, with a full stop added. A seven-letter word reaches the dome, which covers the full stop at the end of the film. The build lists every field that is too long, and the check fails if anything spills or overlaps.
What do visitors see if the film cannot play?
The last frame and the observatory cut out of it, as pictures, with every word in place. That covers reduced motion, no WebGL or GSAP, blocked autoplay, a film that takes more than 8 seconds to start, or a page opened from disk instead of a web server.
Which agents is Desert Observatory 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.
