Web Prototype Skill

Produce a single, self-contained HTML prototype using the bundled seed and layout library — not by writing CSS from scratch. The seed already encodes good defaults (typography, spacing, accent budget). Your job is to compose it.

Workflow

Step 0 — Pre-flight (do this once before writing anything)

1. Read `assets/template.html` end-to-end — at minimum through the <style> block. The class inventory at the top of references/layouts.md lists every class that must be defined there; if one is missing, add it to <style> rather than re-defining it inline on every section.
2. Read `references/layouts.md` so you know which section skeletons exist. Don't write a section type that isn't covered — pick the closest layout and adapt.
3. Read the active DESIGN.md (already injected into your system prompt). Map its colors to the six :root variables in the seed; don't introduce new tokens.

Step 1 — Copy the seed

Copy assets/template.html to the project root as index.html. Replace the six :root variables with the active design system's tokens. Replace the page <title> and the topnav brand.

Step 2 — Plan the section list

Pick layouts before writing copy. Default rhythms (from layouts.md):

State the chosen list in one sentence to the user before writing — they can redirect cheaply now and not after 200 lines of HTML.

Step 3 — Paste and fill

For each chosen layout, copy the <section> block from layouts.md into <main id="content"> of your index.html. Replace bracketed [REPLACE] strings with real, specific copy from the user's brief. No filler — if a slot is empty, the section is the wrong choice; pick a different layout.

Step 4 — Self-check

Run through references/checklist.md top to bottom. Every P0 item must pass before you move on. P1 items should pass; P2 are bonus.

Step 5 — Emit the artifact

Wrap index.html in <artifact> tags. One sentence before describing what's there. Stop after </artifact>.

Hard rules (the seed protects most of these — don't fight it)

• Single accent, used at most twice per screen. Eyebrow + primary CTA is the default budget.
• Display font is serif (Iowan Old Style / Charter / Georgia in the seed). Sans for body. Mono for numerics, captions, eyebrows.
• Image placeholders, not external URLs. Use the .ph-img class — never link to a stock photo CDN.
• Mobile reflow already works via the seed's media query at 920px. Don't break it by adding fixed widths.
• `data-od-id` on every `<section>` so comment mode can target it.

Output contract

<artifact identifier="kebab-case-slug" type="text/html" title="Human Title">
<!doctype html>
<html>...</html>
</artifact>

One sentence before the artifact. Nothing after.
