| description | Produce a world-class single-page editorial landing site in the Atelier Zero visual language (Monocle / Apartamento / Études editorial collage) — the same aesthetic Open Design uses for its own marketing surface. The agent fills a typed `inputs.json` from a brand brief, optionally generates 16 collage assets via gpt-image-2, then runs a pure-function composer that emits a self-contained HTML file; a separate path can mirror the Astro marketing site in `apps/landing-page/`. Drop-in scroll-reveal motion and a Headroom-style sticky nav are wired automatically.

open-design-landing
Build a single-page editorial landing site (or a slide deck — see the
sibling open-design-landing-deck skill)
in the Atelier Zero design system: warm-paper background, Inter
Tight + Playfair Display, italic serif emphasis spans, dotted hairline
rules, coral terminating dots, scroll-reveal motion, and 16 surreal
collage plates.
This is the canonical Open Design marketing-page recipe — the example
output is the very page you see at open-design.
The skill is fully parameterized. The agent fills one typed
inputs.json from the user's brief; the composer turns that JSON +
the canonical styles.css into a deployable artifact.
inputs.json + styles.css 16 image slots
│ │
└──────────► scripts/compose.ts ◄────────────┘
│
▼
<out>/index.html (self-contained)
<out>/assets/ (PNG or SVG)
What you get
A single HTML file with all of:
- Editorial topbar (volume / issue / language strip), Headroom-style
sticky nav with live GitHub star count.
- 8 numbered Roman-numeral sections with paper-textured background:
hero (with 3 stat rings + 4-step index), about, capabilities (4 cards),
labs (5 cards + filter pills + progress bar), method (4 steps with
thumbnails), selected work (dark slab + 2 tilted cards), testimonial
(pull quote + 5 partner glyphs), CTA (ribbon + email pill).
- Footer with 4 link columns + huge italic-serif kicker word.
- Scroll-reveal motion on every section (IntersectionObserver, respects
prefers-reduced-motion).
- Fully responsive at 1280 / 1080 / 880 / 560 breakpoints.
Workflow contract
Run these four steps in order. The agent should complete each step
before moving on, and prefer asking the user a focused question over
inventing copy.
1. Gather brand inputs
Use AskQuestion (or the equivalent in your UI) to collect the brand
brief in chunks; do not dump the entire schema.ts on the user.
Map their answers into inputs.json matching the typed shape.
The eight question groups, in order:
| Group | Schema fields | Min answers | Notes |
|---|
| 1 | brand.{name,mark,tagline,description,location} | 5 | Mark = single glyph (Ø, ▲, ★…) |
| 2 | brand.{license,version,year,primary_url,contact_email} | 4 | URL is required; license defaults Apache-2.0 |
| 3 | nav[] (up to 5) | 3 | Optional count badges |
| 4 | hero.{label,headline,lead,primary,secondary,stats} | All | Headline as MixedText (sans+em+dot) |
| 5 | about + capabilities.cards[4] | All | 4 cards × {num,tag,title,body} |
| 6 | labs.cards[5] + method.steps[4] | All | Both grids fixed-arity |
| 7 | work.cards[2] + testimonial | All | 5 partner glyphs as inline SVG path data |
| 8 | cta + footer.{columns[4],mega} | All | Mega kicker is a MixedText like the headlines |
Open inputs.example.json for a complete
worked example (Open Design itself).
2. Decide the image strategy
| Strategy | When to choose | Cost / latency |
|---|
placeholder | First pass. Demo. Slide internal. No image budget yet. | $0, <1s |
generate | Final delivery. Brand wants original collages. | ~$0.40, ~6 min |
bring-your-own | User has art direction PNGs. Drop them at assets_path. | $0, 0s |
Set inputs.imagery.strategy accordingly.
placeholder — frame mode
npx tsx scripts/placeholder.ts <out>/assets/
Writes 16 .svg files (with .png aliases for compatibility) into
<out>/assets/. Each placeholder shows the slot id, ratio, pixel
dimensions, and the prompt hint from image-manifest.json. The
composer's <img src='./assets/hero.png'> etc. just work.
generate — gpt-image-2 mode
FAL_KEY=... npx tsx scripts/imagegen.ts <inputs.json> --out=<out>/assets/
Calls fal.ai's openai/gpt-image-2 synchronous endpoint per slot.
Composes prompts as: style anchor (paper-collage editorial system)
- brand variables (name / nav / headline / italic emphasis pulled
from
inputs.json) + per-slot composition (e.g. cropped plaster
head + tree growing through arch). Skips slots whose target file
already exists; pass --force to re-render.
Without FAL_KEY, the script prints the prompts so the operator can
route them through the /gpt-image-fal slash-command skill manually.
bring-your-own
Drop 16 PNGs matching assets/image-manifest.json filenames at
inputs.imagery.assets_path. Done.
3. Compose the artifact
npx tsx scripts/compose.ts <inputs.json> <out>/index.html
The composer reads inputs.json and ../styles.css, then writes one
self-contained HTML file. The page includes:
- The full Atelier Zero stylesheet, inlined.
- All section markup with
data-reveal attributes for staggered
scroll motion.
- Inline IntersectionObserver script (mirrors
apps/landing-page/app/_components/reveal-root.tsx).
- Inline Headroom nav script (mirrors
header.tsx).
- Inline GitHub star-count fetcher (auto-detects from
brand.primary_url).
4. (Optional) Mirror the deployable Astro site
For deployable production output, fork the apps/landing-page/
package: copy it into your workspace, align app/page.tsx with content
from your inputs.json, and copy your <out>/assets/*.png into the
paths expected by app/image-assets.ts / R2 URLs. Build with
pnpm --filter @open-design/landing-page build for a static out/
export ready for any CDN.
A future iteration may bundle a composer that emits the full
apps/landing-page/ tree from inputs.json in one command. Until
then, fork-and-edit is the supported path.
Self-check before delivering
Before marking done, the agent must verify:

Boundaries
- Do not invent new colors or typefaces. Tokens live in
design-systems/atelier-zero/DESIGN.md; extend the design system
before adding a new ramp here.
- Do not drop
data-reveal attributes from generated markup.
Without them the page goes static and feels dead.
- Do not wrap the composed HTML in a framework that injects its
own stylesheet ordering — Atelier Zero relies on stylesheet-order
cascade for paper texture and z-index of side rails.
- Do not add a separate stylesheet file for the Astro landing-page
fork; copy
styles.css verbatim into app/globals.css so visual parity
stays one-to-one.
