Use when creating, re-theming, polishing, or migrating a static Astro + Tailwind marketing site for an iOS or macOS app (landing, help, support, privacy, terms). Do not use for SwiftUI app UI, App Store screenshot sets, or general web apps unrelated to Apple product marketing.

The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Update product strings: brand label, nav, footers, titles, meta, domain in astro.config.mjs.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Apple app marketing site

Build calm, monochrome-capable, Apple-inspired static marketing sites for consumer iOS/macOS apps. Prefer Astro + Tailwind v4, system fonts, zero third-party analytics, and shared layout components.

When to use

  • New app marketing site under web/ (or similar) in a consumer app repo
  • Visual polish / Apple-marketing redesign of an existing static landing site
  • Re-theme of a prior site for a new product (colors, brand, fonts, assets)
  • Migration from Vite multi-page HTML to Astro while preserving routes and legal copy

When not to use

  • Native SwiftUI screens or in-app design tokens → $apple-design-system / $swiftui-component-author
  • App Store marketing screenshots and device frame exports → $app-store-screenshots
  • Complex SaaS web apps, auth, CMS, or server forms

Inputs: product name, domain, support email; routes and page content (or permission to scaffold placeholders); theme intent (light-first monochrome default, or accent / dual appearance); privacy posture (local-first messaging is common).

Output: static Astro site with BaseLayout, Header, Footer, and design tokens in global.css; content-faithful pages (legal/help unchanged unless requested); Vercel-ready build with trailing-slash routes; clear re-theme edit points for the next product clone.

Architecture (copy this shape)

web/
├── astro.config.mjs      # site URL, trailingSlash: "always"
├── vercel.json
├── package.json

    ├── pages/            # index, help/, support/, privacy/, terms/
    └── styles/global.css # @theme tokens — primary re-theme surface

Typical routes: /, /help/, /support/, /privacy/, /terms/.

Design principles (from the polish reference)

  1. Type-led hierarchy — display headlines with tight tracking; restrained body size and muted color.
  2. Generous whitespace — section padding ~96–128px desktop; avoid dense SaaS chrome.
  3. Monochrome default — near-black ink CTAs and links; accent optional via tokens.
  4. Minimal decoration — one premium device treatment; no sticker collages or heavy gradients.
  5. Device mockup — near-upright CSS iPhone, soft ground shadow, no floating badges.
  6. Static chrome — header/footer in HTML at build time (never JS-injected).
  7. Privacy-respecting — no third-party scripts; support via client mailto: only.

Re-theme checklist (under one hour)

  1. Edit @theme tokens in src/styles/global.css (colors, fonts, shadows, radii).
  2. Update product strings: brand label, nav, footers, titles, meta, domain in astro.config.mjs.
  3. Replace public/ favicons (and OG image if present).
  4. Adjust BrandMark.astro or swap for a logo image in public/.
  5. Rewrite homepage copy and PhoneMockup screen content for the new product.
  6. Port help/support/legal content or keep structure and replace article bodies carefully.
  7. Set site URL and Vercel root; run npm run build.

Full token tables, component inventory, and page patterns:

  • references/retheme-guide.md
  • references/structure-and-pages.md
  • references/landing-page-recipe.md — proven homepage anatomy (screens, benefits, social proof, pricing, FAQ), real-screenshot capture, and the mandatory link/form/width verification pass

Human-facing template pack (copy into consumer projects): repository path Templates/AppMarketingSite/ (README.md, RETHEME.md, STRUCTURE.md, CHECKLIST.md, LANDING_RECIPE.md, TOKEN_REFERENCE.css).

Implementation order

  1. Scaffold Astro + Tailwind in web/; configure site + trailing slashes.
  2. Tokens + BaseLayout / Header / Footer (static).
  3. Homepage (hero, trust, screenshot gallery, benefits, clarity visual, social proof, pricing, FAQ, final CTA band — anatomy in references/landing-page-recipe.md).
  4. Secondary pages with shared PageIntro + LegalProse.
  5. Minimal islands only where needed.
  6. npm run build; responsive pass; Vercel config.

Verification

cd web && npm run build

Confirm routes emit under dist/ with trailing-slash directories, header/footer present without client JS, and no third-party script tags. Then run the full verification pass (every link, forms, desktop + mobile widths, a11y spot-checks) described in references/landing-page-recipe.md.

Reference implementation

Consumer example of this polish language: a consumer app marketing site (<App>/web/) — monochrome light-first Astro + Tailwind. Do not copy product-specific legal text; copy structure, tokens, and components.
