threads-carousel-claude-skill

A Claude Code skill that converts text posts into visual carousel images for Threads, Instagram, LinkedIn, TikTok, and Stories.

Paste a text post (or a Markdown file) into Claude, say "сделай карусель" / "make a carousel", and get a browser preview with exportable PNGs or a single PDF. Composable design system with four independent style axes, 12 slide types, 8 background decorations, and multi-platform format presets.

Features

• 12 slide types — hook, body, list, stats, quote, checklist, process, comparison, cta, image (text + photo/screenshot), emoji (giant illustration), number (hero digit) + a points variant of body for ✓/✗ pro/con lists with SVG icons
• 6 format presets — Threads 4:5, Instagram square, LinkedIn document PDF, TikTok 9:16, Stories 9:16, Wide 16:9 (1920×1080 for presentations / YouTube)
• 4-axis style system — pick font × surface × accent × purpose independently:
  • Font (5): Minimal (Unbounded), Editorial (Playfair), Clean (Inter), Mono (JetBrains Mono), Condensed (Oswald)
  • Surface (8): Dark, White, Light, Paper, Gradient, Pastel, Neon, Ember — background + text neutrals
  • Accent (11): Yellow, Red, Teal, Coral, Orange, Violet, Lime, Blue, Fuchsia, Pink, Amber — the pop color for highlighted words
  • Purpose: Carousel (bold 44px uppercase titles) or Presentation (72px sentence case, lighter body)
  • Total: 5 × 8 × 11 × 2 = 880 valid style combinations
• 8 background decorations — none, organic blobs, dot grid, diagonal lines, ruled paper (notebook lines with margin), SVG noise, big number watermark, radial glow
• Highlighted keywords — any word in title or body colored in the accent color, with optional italic-box style (Playfair italic on a colored rectangle)
• Image support — drop PNG/JPG files into template/public/images/ and reference via imageSrc: "/images/file.png" in any image slide
• Badges — small outlined tags above titles (01, 02, TIP, NEW)
• Text balance — text-wrap: balance on hooks and titles to prevent orphan words
• Adaptive typography — font size scales to content length
• Modular architecture — content in src/slides.ts, engine in src/app/CarouselApp.tsx + src/lib/
• Live preview toolbar — switch format, purpose, font, surface, accent, and background in the browser without editing code
• RU/EN toolbar — UI labels toggle between Russian and English
• PNG export — download individual slides or all at once via html-to-image
• PDF export — all slides in a single file via jsPDF (JPEG-compressed, ~5–8 MB for 10 slides)

Quick start

As a Claude Code skill

1. Clone the repo into your Claude skills directory:

   mkdir -p ~/.claude/skills
   git clone https://github.com/itchernetski/threads-carousel-claude-skill.git ~/.claude/skills/threads-carousel

2. Install template dependencies (one-time):

   cd ~/.claude/skills/threads-carousel/template
   bun install   # or pnpm / npm

3. In Claude Code, trigger the skill by pasting a post and saying:

   Сделай карусель из этого поста

   or: Make a Threads carousel from this text

Claude reads the text, splits it into slides, edits src/slides.ts in a temporary working copy of the template, launches bun dev on port 3333, and hands you the preview URL.

Standalone (without Claude)

You can also use the template directly as a Next.js carousel generator:

cd template
bun install
# Edit src/slides.ts with your content
bun dev --port 3333
# Open http://localhost:3333
# Click "Export All" to download PNGs

The golden rule: to change carousel content, only touch src/slides.ts. Everything else is the engine.

Slide types reference

Each slide is an object in the SLIDES array with a type field and type-specific fields:

// hook — opening slide
{ type: "hook", text: "Claude Code\nis smarter with skills", highlight: "skills" }

// body — title + paragraph
{ type: "body", badge: "01", title: "Title", text: "Body text", highlight: "key" }

// body with points — pros/cons list with ✓/✗ SVG icons
{ type: "body", badge: "03", title: "Pros & Cons", points: [
  { type: "plus",  text: "One click to register" },
  { type: "plus",  text: "Works on any background" },
  { type: "minus", text: "Requires provider setup" },
]}

// list — numbered items
{ type: "list", title: "Steps", items: ["First", "Second", "Third"] }

// stats — big numbers
{ type: "stats", title: "Impact", stats: [
  { value: "3×", label: "More saves" },
  { value: "40%", label: "Faster" },
]}

// quote — pulled quote
{ type: "quote", text: "Quote text", author: "Someone", role: "2026" }

// checklist — checkmarks
{ type: "checklist", title: "Pre-flight", items: ["One", "Two", "Three"] }

// process — numbered steps with connector
{ type: "process", title: "How it works", steps: [
  { title: "Step 1", text: "Description" },
  { title: "Step 2", text: "Description" },
]}

// comparison — two-column VS
{ type: "comparison", title: "Before vs after",
  leftLabel: "Before", leftItems: ["Slow", "Manual"],
  rightLabel: "After", rightItems: ["Fast", "Automated"],
}

// cta — final call to action
{ type: "cta", text: "Follow for more", handle: "@username" }

// image — text + photo/screenshot (file in template/public/images/)
{ type: "image", badge: "02", title: "GitHub Trending",
  imageSrc: "/images/screenshot.png",
  imageCaption: "source: github.com/trending" }

// emoji — giant 360px emoji illustration + title + text
{ type: "emoji", emoji: "🚀", title: "Ship it", text: "Done beats perfect." }

// number — hero digit/string (up to 560px, auto-scales) + title + text
{ type: "number", bigNumber: "88", title: "color combos",
  text: "8 surfaces × 11 accents — independent axes." }

Italic-box highlight style

Any slide with a highlight field can opt into a stylized highlight — Playfair italic on a colored rectangle (Karpathy-style):

{ type: "hook", text: "Carousels that\nactually pop",
  highlight: "pop",
  highlightStyle: "italic-box" }

Defaults

• Font: minimal (Unbounded throughout)
• Surface: dark (black background, white text)
• Accent: yellow (#FACC15 highlighted words)
• Purpose: carousel (bold 44px uppercase titles with divider)
• Background: glow (soft radial gradient in alternating corners)
• Format: threads-4x5 (1080×1350)
• Padding: 80px, left-aligned

Change any of these in src/slides.ts via DEFAULT_FONT, DEFAULT_SURFACE, DEFAULT_ACCENT, DEFAULT_PURPOSE, DEFAULT_BG, and DEFAULT_FORMAT. For a presentation deck, set DEFAULT_PURPOSE = "presentation" and DEFAULT_FORMAT = "wide-16x9".

Great combos to try: dark + teal (noir tech), paper + orange (literary warm), ember + lime (dramatic announcement), white + coral (sharp editorial), pastel + fuchsia (playful), gradient + amber (radiant).

Design system

Sizes below are for the default carousel purpose. The presentation purpose overrides titles to 72px / weight 700 / sentence case / no divider, and body to weight 400 / textSecondary / line-height 1.45. Fonts follow the active font axis — Unbounded display accents are used only when the font axis provides hookFontFamily (Minimal preset).

Element	Size	Weight	Font axis
Hook	88–170px (adaptive)	800	hookFontFamily ?? fontFamily
Title	44px	800 uppercase	fontFamily
Body	48–88px	600	fontFamily
Points (pros/cons)	44–62px	600	fontFamily
Badge	26px	800 uppercase	fontFamily
Stats value	140–170px	900	fontFamily
Quote	62px	600	fontFamily
List item	46px	600	fontFamily
Handle	36px	500	fontFamily
Emoji hero	360px	—	OS emoji font
Big number	320–560px (auto)	900	hookFontFamily ?? fontFamily
Image caption	40px	500	fontFamily

Tech stack

• Next.js 15 — React framework + next/font/google for font loading
• React 19 — rendering
• TypeScript 5 — type safety
• Tailwind CSS 4 — minimal usage (mostly for reset)
• html-to-image — client-side PNG / JPEG export
• jspdf — multi-slide PDF export (dynamic import to avoid Next.js 15 webpack ESM issue)
• Unbounded + Inter + Playfair Display + JetBrains Mono + Oswald + Space Grotesk — via Google Fonts

Customization

Adding a new font

Add an entry to FONT_STYLES in src/lib/presets.ts and extend the FontId union in src/lib/types.ts:

brand: {
  id: "brand",
  name: "Brand",
  fontFamily: "var(--font-your-font)",   // applied to titles, body, badges, stats, handles
  hookFontFamily: "var(--font-your-display)",  // optional, hook-only display font
},

Adding a new surface

Add an entry to SURFACES and extend the SurfaceId union in src/lib/types.ts:

midnight: {
  id: "midnight",
  name: "Midnight",
  bg: "#0A0A1F",
  bgGradient: undefined,       // optional CSS gradient (overrides bg)
  textColor: "#E0E7FF",
  textSecondary: "rgba(224,231,255,0.5)",
  accentColor: "#E0E7FF",      // titles, dividers, decorative elements
},

Adding a new accent

Add an entry to ACCENTS and extend the AccentId union:

rose: { id: "rose", name: "Rose", color: "#F43F5E" },

Available font CSS variables (already loaded via Google Fonts):

• --font-unbounded — geometric display, bold
• --font-space-grotesk — modern grotesque
• --font-inter — neutral sans-serif
• --font-playfair — classic serif
• --font-jetbrains-mono — monospace, tech feel
• --font-oswald — narrow condensed, poster feel

Then set DEFAULT_FONT / DEFAULT_SURFACE / DEFAULT_ACCENT in src/slides.ts to your new ids. Font × surface × accent × purpose are composed into a final StylePreset at runtime by composePreset().

To add a new font: import it in src/app/layout.tsx via next/font/google, add a CSS variable, and reference it in a FONT_STYLES entry.

Modifying format presets

Add a new entry to FORMAT_PRESETS in src/lib/presets.ts and update the FormatId union type in src/lib/types.ts.

Roadmap

• Runtime format switcher — in the toolbar, resizes canvas live (shipped in #1).
• PDF export — all slides in a single file via jsPDF (shipped in #1).
• Image / emoji / number slide types — shipped in v1.2.0.
• Split surface + accent axes — 88 color combos via independent axes, shipped in v1.2.0.
• Mono + Condensed fonts + italic-box highlight + ruled-paper bg — shipped in v1.2.0.
• Satori + Resvg server-side export — replace browser-based html-to-image with headless PNG generation for sharper output and CLI use. See Slashgear/linkedin-carousel-gen for reference.
• Per-slide background override — different bg type per slide.
• Cyrillic-optimized defaults — adjust adaptive sizing thresholds for Russian/Cyrillic text density.
