mobile-app
A mobile-app screen rendered inside a pixel-accurate iPhone 15 Pro frame on the page. Built by copying the seed `assets/template.html` and pasting one screen archetype from `references/layouts.md`. Use when the brief asks for "mobile app", "iOS app", "Android app", "phone screen", or "app UI".
Mobile App Skill

Workflow
Step 0 — Pre-flight
- Read
assets/template.htmlend-to-end through the<style>block. The Dynamic Island, status bar SVG icons, home indicator, side rails, and tab bar are all already drawn in HTML/SVG — do not re-implement them inline on each screen. - Read
references/layouts.mdso you know which 6 archetypes exist. - Read the active DESIGN.md — map its tokens to the six
:rootvariables in the seed.
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 caption above the device.
Step 2 — Pick exactly one archetype
| Brief language | Use | |---|---| | feed, inbox, timeline, list, messages, notifications | A — Feed | | article, post, item, recipe, song, product, song detail | B — Detail | | sign-up, welcome, intro, walkthrough, tour | C — Onboarding | | profile, account, user page, someone's bio | D — Profile | | checkout, payment, order, form, settings step | E — Checkout | | timer, map, dashboard widget, single big number | F — Focus / hero card |
A mobile screen does one job. If the brief seems to combine two, ship one screen and offer the other as a follow-up.
Step 3 — Paste and fill
Copy the archetype block from layouts.md into <main class="content">, replacing the placeholder card. Fill bracketed text with real, specific copy from the brief. Drop the <nav class="tabbar"> block entirely for archetypes that don't show one (B, C, E).
Step 4 — Self-check
Run through references/checklist.md. Pay extra attention to:
- Frame still has the Dynamic Island, status bar SVGs, and home indicator
- Tap targets ≥ 44px
- One accent, used ≤ 2× on the screen
- Display headings still use
var(--font-display)(serif)
Step 5 — Emit the artifact
<artifact identifier="mobile-slug" type="text/html" title="Mobile — Screen Name">
<!doctype html>
<html>...</html>
</artifact>
One sentence before describing what's there. Stop after </artifact>.
Hard rules
- The phone is real. Dynamic Island gap, SVG status icons, home indicator. The seed protects all three — don't rewrite the frame.
- Single screen, single job. No multi-tab tours, no spliced flows.
- Accent budget = 2. One active tab + one primary action is the default.
- Numerics in mono via
.numclass. - Display in serif via
var(--font-display). - No external images — use
.ph-imgplaceholders.
