Skill: carousel-slide

Produces a single self-contained HTML file containing N pixel-exact 1080×1080 canvas divs. Each canvas is an individual carousel slide; screenshot each separately at native dimensions to upload as a multi-slide post on LinkedIn or Instagram.

The carousel format is high-leverage for editorial brands — it lets the brand's longer-form thinking land in a feed that otherwise rewards single posts. The discipline: cover and closing slides do the visual work; middle slides do the content work.

When to use

• User wants a multi-slide carousel post (LinkedIn or Instagram)
• A DESIGN.md exists for the brand

Inputs

• Required: brand slug, post topic / thesis
• Optional: number of slides (default 5: cover + 3 content + closing), CTA text for closing slide
• Optional: content for each middle slide (or leave for the agent to draft from the topic)

Output

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

Steps

1. Verify brand exists

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

2. Gather the brief

Ask in one message:

1. Topic / thesis — the carousel's argument in one sentence (sentence-case ending in period per brand voice)
2. Number of slides — default 5 (1 cover + N content + 1 closing CTA); valid range 3–9 (carousel max)
3. Per-slide content — optional. If omitted, the agent drafts from the topic.
4. Closing CTA — the action you want readers to take (e.g. "read the full piece at shane.logsdon.io")

3. Pick variations — DIFFERENT archetypes for cover, content, closing

Carousel formats reward visual variation between cover and content. The discipline:

Cover slide (slide 1) — picks from the most distinctive archetypes:

• single-word — one massive Fraunces serif word
• inverse-text — full canvas dark inversion with the carousel's claim as the headline
• number-led — the topic's defining stat dominates the cover
• type-only — the topic statement at maximum scale, no chrome

Content slides (slides 2 through N-1) — picks from CONSISTENT archetypes (slides should feel like a series, not a deck of mismatched cards):

• chrome-led — running head + numbered headline + brief body
• object-of-content — looks like a fragment from the brand's actual writing
• pattern-led — typographic pattern with a punctum

Closing slide (slide N) — picks from action-oriented archetypes:

• chrome-led with explicit CTA
• inverse-text with the CTA as the carved headline
• single-word ("more.") with URL beneath

Color treatment must hold across all slides for series coherence: cream-page | inverted-feature-on-cover (cover dark, body cream, closing dark to bookend) | full-cream.

Cross-artifact rule: if a recent carousel for this brand used a particular cover archetype, vary it.

4. Generate the HTML

Template:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title><Brand> — Carousel — <topic></title>
<link rel="preconnect" href="https://fonts.googleapis.com">

<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; font-family: var(--type-sans-family); }
body { display: flex; flex-direction: column; align-items: center; gap: 32px; padding: 32px 0; }

.slide-label { font-family: var(--type-mono-family); font-size: 12px; letter-spacing: 0.14em; text-transform: uppercase; color: rgba(255,255,255,0.7); align-self: center; }

/* All slides at exact 1080×1080 */
.canvas {
  width: 1080px; height: 1080px;
  background: var(--color-surface);
  color: var(--color-ink);
  position: relative; overflow: hidden;
  padding: 80px;
  box-sizing: border-box;
  display: grid;
}

/* Cover slide — strongest treatment */
.canvas--cover { /* style per cover archetype: single-word / inverse-text / etc. */ }

/* Content slide — consistent archetype across slides 2..N-1 */
.canvas--content {
  grid-template-rows: auto 1fr auto;
  gap: 32px;
}

/* Closing slide — action-oriented */
.canvas--closing { /* style per closing archetype */ }

/* Slide-position folio (same as page numbers in a magazine) */
.slide-folio {
  position: absolute; bottom: 64px; right: 64px;
  font-family: var(--type-mono-family); font-size: 14px; letter-spacing: 0.06em;
  color: var(--color-ink-3);
}
.slide-folio .pos { color: var(--color-ink); }

@page { size: 1080px 1080px; margin: 0; }
</style>
</head>
<body>

<article class="canvas canvas--closing">
  <!-- closing CTA per archetype -->
  <span class="slide-folio"><span class="pos">05</span> / 05</span>
</article>
</body>
</html>

5. Per-slide content guidance

• Cover (slide 1): the carousel's claim or topic, set at maximum scale per chosen archetype. NO chrome (no eyebrow, no body text). The cover IS the hook.
• Content slides (slides 2..N-1): each carries ONE point. Format: small running head + headline (24–48px) + brief body (1–3 sentences). Numbered ordinal in marginalia. Slides build on each other.
• Closing (slide N): the action — read the full piece, subscribe, follow, etc. Either chrome-led with explicit CTA OR inverse-text with the CTA carved as the dominant element.

6. Verify

• All N canvases at exact 1080×1080
• Cover archetype documented AND distinct from content archetype
• Content slides consistent in archetype (so they read as a series)
• Closing slide has clear action / next step
• Slide folios (01/05, 02/05, etc.) on every slide for orientation
• Read ../../design-anti-patterns.md and verify the artifact violates none of its rules. Pay special attention to sections 2 (no italics-emphasis OR single-word color emphasis), 4 (architecture must reach inner blocks; no top-metadata-row eyebrow disguise), 5 (no editorial-cosplay markers unless brand-earned), and 7 (cross-artifact rules)
• Type-accent (one word in --color-accent) appears AT MOST once across the whole carousel — typically on the cover or closing
• Companion text drafted (LinkedIn post or IG caption) accompanies the file in an HTML comment

Carousel artifact at ./design/<brand-slug>/artifacts/carousel-YYYY-MM-DD-<slug>.html.

Variations: cover <arch> · content <arch> · closing <arch> · color <picked>.

Export: open in browser → DevTools → device toolbar → 1080×1080 viewport → screenshot each .canvas separately. Upload as multi-slide post in LinkedIn or Instagram in slide-folio order.

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

• Pixel exactness on every slide. 1080×1080, no flex.
• Cover and closing get the most distinctive treatments. Middle slides serve content; bookends serve attention.
• Slide folios mandatory. Each slide gets its position marker (01/05, 02/05) — readers need orientation in carousel UIs.
• Companion text included. LinkedIn or IG caption drafted for the post body.
• Token-pure. Every visual value via var(--*) from tokens.css.
• 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.
