Generate a podcast cover artifact — pixel-exact 1500×1500 square HTML canvas (half of Apple Podcasts' 3000×3000 spec for manageable PNG size; export the screenshot at 2× scale via DevTools for actual upload). Bold, legible at app-icon scale (~120×120). Reads ./design/<brand-slug>/DESIGN.md, tokens.css, and components.html. Triggers include "podcast cover for X", "podcast art", "show cover", "/podcast-cover".

Skill: podcast-cover

Produces a pixel-exact 1500×1500 square HTML canvas. The defining constraint: the cover must read clearly at 120×120px (typical app-icon scale in Apple Podcasts / Spotify / Pocket Casts). Bias toward fewer words, larger type, higher contrast than other platform skills. Bold typographic treatment, no decoration.

When to use

User has (or is launching) a podcast and wants cover art
A DESIGN.md exists for the brand

Inputs

Required: brand slug, show title (max 4 words for legibility at icon scale)
Optional: tagline (max 6 words), wordmark/host name placement

Output

./design/<brand-slug>/artifacts/podcast-cover-YYYY-MM-DD-<slug>.html

Steps

1. Verify brand exists

test -f ./design/<brand-slug>/tokens.css

If missing, stop and tell the user to run /design-system <brand-slug> first.

2. Gather the brief

Ask in one message:

1. Show title (max 4 words — push back if longer; app-icon legibility is the constraint)
2. Optional tagline / category (max 6 words; will appear small)
3. Optional host name placement (corner mark, footer, or absent)

If the user gives 5+ words for the title, push back: "Cover art at 120×120 won't hold more than 4 words legibly. What's the core?" Don't proceed until they agree.

3. Pick variation — ARCHITECTURE FIRST

Pick ONE. Podcast covers reward boldness:

single-word — one massive word fills the canvas. Strongest at icon scale.
type-only — short title (2-4 words) at extreme scale; no meta, no decoration.
inverse-text — full canvas dark inversion (canonical v2 feature treatment) — the title in cream on ink. The contrast helps at small sizes.
number-led — episode/season number dominates (for serial / numbered shows).
chrome-led — title + tagline + corner mark. Last resort. Rarely warranted at this scale.

Then pick:

Layout: centered | top-anchored | bottom-anchored | corner-anchored
Color usage: monochrome | single-accent | inverted (inversion is often strongest at icon scale)

Cross-artifact rule: if the brand has a previous cover (e.g. season 1 vs season 2), pick a different archetype OR a different color treatment.

4. Generate the canvas HTML

Template:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title><Brand> — Podcast cover — <show title></title>
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=<families>&display=swap">
<style>
/* Embed tokens.css verbatim */
<contents of tokens.css>

html, body { margin: 0; padding: 0; background: #2a2a2a; min-height: 100vh; display: grid; place-items: center; font-family: var(--type-display-family); }

.canvas {
  width: 1500px;
  height: 1500px;
  background: var(--color-surface);    /* or --color-ink for inversion */
  color: var(--color-ink);
  position: relative;
  overflow: hidden;
  padding: 80px;
  box-sizing: border-box;
  display: grid;
  /* Layout per variation */
}

/* The display title — must be MASSIVE for icon-scale legibility */
.title {
  font-family: var(--type-display-family);
  font-weight: 500;
  font-size: clamp(280px, 30vw, 480px);
  line-height: 0.92;
  letter-spacing: -0.025em;
  margin: 0;
  color: var(--color-ink);    /* or surface for inversion */
}

@page { size: 1500px 1500px; margin: 0; }
</style>
</head>
<body>
<!--
Variation choices:
  archetype: <picked>
  layout:    <picked>
  color:     <picked>

Show title (on canvas): "<title>"
-->
<article class="canvas">
  <!-- title content per archetype -->
</article>
</body>
</html>

For the title itself:

single-word: ONE word at 400-480px Fraunces (or brand display family); period as the only ornament
type-only: 2-4 word title at 280-360px, hand-broken across multiple lines for typographic rhythm
inverse-text: full canvas dark; title in cream at maximum scale
number-led: massive numeral (e.g. "47" for episode 47) with title small beneath

5. Test legibility (mental check)

Imagine the canvas scaled to 120×120px (typical app-icon size). At that size:

Can you read the title in under 1 second?
Is the contrast strong enough to pop against a feed of similar covers?
Is the host name / tagline (if present) tiny enough to disappear gracefully — or does it need to GO entirely?

If "no" to the first two, the title is too small or contrast too low. Bump scale up or switch to inversion.

6. Verify and report

Canvas is exactly 1500×1500
Architecture archetype documented AND differs from the most recent artifact in this brand
Title is at most 4 words
Display type at minimum 280px (typical: 360–480px)
Read ../design-anti-patterns.md and verify the artifact violates none of its rules. Pay special attention to sections 2 (no italics OR single-word color emphasis) and 5 (no editorial-cosplay markers)
No more than 1 type family at icon scale; mono allowed only for tiny meta if at all
No accent color on a single punctuation mark (clever-AI tell)
Brand mark, if present, is unobtrusive — corner placement, max 24px font-size

Podcast cover at ./design/<brand-slug>/artifacts/podcast-cover-YYYY-MM-DD-<slug>.html.

Variation: <archetype> × <layout> × <color>.

Export at 3000×3000 for Apple Podcasts: open in browser → DevTools → device toolbar → 1500×1500 viewport → screenshot at 2x device scale. Or use a screenshot tool that supports 2x export.

Anti-Slop Rules

Governed by three shared canonical references — read them, do not restate them:

../design-anti-patterns.md — the hard floor. Wins every conflict.
../design-principles.md — the craft floor (typographic hierarchy, spatial rhythm, color theory, layout logic, visual tension).
../design-variation-sop.md — the named-aesthetic roster + the procedure for varying every invocation.

Forbidden (fast scan — the references hold the full list):

Indigo/violet/purple as default accent or primary — the hsl(230–280) family on a near-white surface. The single loudest AI tell.
Purple→blue / "aurora" / gradient-mesh backgrounds; gradient-fill text.
Glassmorphism without an explicit AA-contrast scrim; floating gradient "blobs" as atmosphere.
The three-up icon-card feature grid; the "hero → 3 cards → CTA" median skeleton.
One global border-radius on every element; timid evenly-weighted low-contrast palette.
Inter / Roboto / Arial / Open Sans / Lato / Helvetica / system as the primary family (Space Grotesk = yellow flag). Use a category-matched stack from the variation roster.
Value-free CTAs ("Get Started", "Learn More", "Sign Up"); the two-CTA hero. Name the real action and its value.

Required variation (every invocation):

Make at least two intentional decisions that differ from the safe defaults (palette, layout structure, typographic voice, or spatial density) AND from the most recent artifact in this brand.
Never default to "clean / minimal / modern" — that is the absence of a direction (variation-sop Rule 1).
Sketch three distinct directions, offer them as a one-line menu, generate the best-fit by default, all three only if asked (variation-sop Rule 3).

Authenticity: prefer specific over generic everywhere — real datelines (not "today"), the brand's actual voice (not "build the future" filler), concrete CTAs over placeholders.

Rules

Title word count is hard-capped at 4. Push back on the user if they want more. App-icon legibility is non-negotiable.
Pixel exact. 1500×1500, no flex.
Token-pure. Every value via var(--*) except 1px for borders and the canvas pixel dimensions.
Display scale floor: 280px. Smaller doesn't survive icon-scale display.
Anti-pattern compliance. This skill defers to three shared canonical references: ../design-anti-patterns.md (the hard floor — wins every conflict), ../design-principles.md (the craft floor), and ../design-variation-sop.md (direction roster + offer-3 procedure). The anti-patterns file is the canonical anti-tell list. If you find a new tell in the output, add it there.
