instagram-tweet-carousel

description

Creates high-quality Instagram carousels in an X (Twitter) post visual format, delivered as swipeable HTML previews with export-ready slides (1080×1350px PNG). Handles the full workflow: brand setup, slide copy, X-style visual design (profile header, clean background, X engagement bar), HTML generation, and Playwright-based export. Use this skill whenever the user asks to create, design, or generate an Instagram carousel in tweet-style or X-style format (e.g., "tweet-style carousel", "X-style carousel", "carrossel estilo tweet", "carrossel estilo X"), including requests for carrossel, Instagram slides, or any multi-image Instagram post — even if they don't explicitly mention "carousel" or "skill". Also trigger for requests like "create a post with multiple slides", "make a tweet-style/X-style carousel", or "export slides for Instagram" in this format.

Instagram Tweet-style Carousel Generator (X / Twitter Layout)

Generates fully self-contained, swipeable HTML carousels where every slide mimics an authentic X (Twitter) post — designed to be exported as individual 1080×1350px PNGs for Instagram.

Working Directory Rules

All file operations MUST use the current working directory (cwd) as the base. Never use hardcoded absolute paths like C:\Users\marco\.

• Detect cwd at the start of every session using pwd or os.getcwd()
• Save all generated files (HTML, PNGs) relative to cwd
• The ASSETS/ folder is always {cwd}/ASSETS/
• The .claude/launch.json is always {cwd}/.claude/launch.json
• The export output folder is always {cwd}/slides/
• Never scan directories outside of cwd for project files or images

---

Step 0 — Ask Background Preference First

Before collecting any other details, always ask:

"Você prefere o fundo claro (branco, estilo X padrão) ou escuro (preto, estilo X dark mode)?"

This choice determines the entire color system and font colors. Do not proceed until the user answers.

---

Step 1: Collect Brand Details

After background preference is confirmed, ask for:

1. Display name — shown in the post header (e.g., "Marco Lang")
2. X handle — shown below the name (e.g., @marcolang)
3. Verified badge — blue checkmark yes/no (default: yes)
4. Profile photo — before asking the user anything about the photo, search in this order:
   1. {cwd}/assets/ — check the project folder first (case-insensitive: assets/ or ASSETS/)
   2. Skill folder assets/ — if not found above, check the skill's own assets folder at ~/.claude/skills/instagram-carousel-tweet/assets/
   • Use the Glob tool or ls to list files in each location
   • If an image file is found (JPG, PNG, WEBP) in either location, use it automatically and tell the user which file was picked — do not ask
   • Only ask the user to provide a photo if no image is found in either location
5. Content / topic — what the carousel is about
6. Idioma dos slides — default: Português (BR) unless specified otherwise
7. Number of slides — default: 7

If the user provides a website URL or brand assets, derive name and handle from those.

If the user says "make me a carousel about X" without brand details, ask before generating. Don't assume defaults.

Handling User-Provided Images

This section applies from the very first HTML generation — not only during export.

The profile photo will be located inside the ASSETS/ folder in the working directory. Always:

1. Find the file in ASSETS/ (e.g., ASSETS/foto.jpg, ASSETS/profile.png)
2. Check the actual file format with the file command — extension may lie
3. Embed as base64 data: URI — never use relative paths

⚠️ Critical Rules

1. NEVER use relative paths (ASSETS/foto.jpg) — they break in every browser context except the exact folder the HTML lives in.
2. NEVER use background: url(filepath) — leads to 1.5MB+ base64 inline strings that crash the browser parser.
3. ALWAYS embed as base64 data: URI — works in preview, export, and any environment.
4. ALWAYS generate the HTML via Python (Path.write_text()) — shell heredocs interpolate $ and backticks, corrupting base64 strings.

Step-by-step: embed the profile photo

# 1. Check the actual file format (extension may lie)
file ASSETS/profile.jpg

import base64
from pathlib import Path

# 2. Read and encode
img_path = Path("ASSETS/profile.jpg")  # adjust filename
# Use "image/jpeg" if `file` command says JPEG, else "image/png"
mime = "image/jpeg"  # or "image/png"
b64 = base64.b64encode(img_path.read_bytes()).decode()
avatar_uri = f"data:{mime};base64,{b64}"

# 3. Inject into HTML template as a Python variable — never via shell
html = f"""...<img src="{avatar_uri}" style="width:100%;height:100%;object-fit:cover;">..."""

Path("carousel.html").write_text(html, encoding="utf-8")

Common image mistakes to avoid

Mistake	What goes wrong	Fix
<img src="ASSETS/foto.jpg">	Broken image in browser	Always use base64 data: URI
background: url('data:...') inline with 1.5MB base64	Browser parser crash	Use <img> tag with object-fit:cover
Generating HTML via shell heredoc	$ and backtick chars corrupt base64	Always use Python Path.write_text()
Assuming .png extension = PNG	Wrong MIME type breaks rendering	Run file command first

---

Step 2: Color System

Two modes only — no gradients, no brand-derived palettes. The X aesthetic is deliberately minimal.

Light Mode (fundo claro)

SLIDE_BG        = #FFFFFF          // Slide background
TEXT_PRIMARY    = #0F1419          // Display name, tweet body text
TEXT_MUTED      = #536471          // Handle, timestamps, muted labels
DIVIDER         = #EFF3F4          // Separator lines, borders
ICON_COLOR      = #536471          // Engagement icons
X_BLUE          = #1D9BF0          // Verified badge, links, accent
SLIDE_NUM_BG    = rgba(0,0,0,0.06) // Slide counter pill background
SLIDE_NUM_TEXT  = #536471          // Slide counter text

Dark Mode (fundo escuro)

SLIDE_BG        = #000000          // Slide background
TEXT_PRIMARY    = #E7E9EA          // Display name, tweet body text
TEXT_MUTED      = #71767B          // Handle, timestamps, muted labels
DIVIDER         = #2F3336          // Separator lines, borders
ICON_COLOR      = #71767B          // Engagement icons
X_BLUE          = #1D9BF0          // Verified badge, links, accent
SLIDE_NUM_BG    = rgba(255,255,255,0.08) // Slide counter pill background
SLIDE_NUM_TEXT  = #71767B          // Slide counter text

---

Step 3: Typography

X uses a system font stack. Use Inter from Google Fonts as the closest equivalent.

<link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&display=swap" rel="stylesheet">

Font size scale:

• Display name: 16px, weight 700, color TEXT_PRIMARY
• Handle: 15px, weight 400, color TEXT_MUTED
• Tweet body: 20px, weight 400, line-height 1.55, color TEXT_PRIMARY (Large text makes each slide readable at a glance — key for Instagram carousels)
• Engagement counts: 13px, weight 400, color TEXT_MUTED
• Slide counter: 13px, weight 500

Apply via CSS class .x-font using font-family: 'Inter', -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif.

Slide Structure (X Post Layout)

Every slide is an exact replica of an X post. Structure from top to bottom:

┌─────────────────────────────────────┐  ← SLIDE_BG background
│  [Avatar] Display Name ✓            │  ← Profile header (always on every slide)
│           @handle                   │
├─────────────────────────────────────┤  ← thin divider (DIVIDER color)
│                                     │
│   Tweet body text goes here.        │  ← Content area (large, readable)
│   It can span multiple lines        │
│   and fill most of the slide.       │
│                                     │
├─────────────────────────────────────┤  ← thin divider
│  💬 Reply  🔁 Repost  ♡ Like  📊   │  ← X engagement bar (decorative)
│                              [1/7]  │  ← Slide counter (right side)
└─────────────────────────────────────┘

Profile Header

<div class="x-header" style="display:flex;align-items:center;gap:12px;padding:20px 20px 14px;">
  <!-- Avatar: circular, 48px, profile photo -->
  <div style="width:48px;height:48px;border-radius:50%;overflow:hidden;flex-shrink:0;">
    <img src="{avatar_uri}" style="width:100%;height:100%;object-fit:cover;">
  </div>
  <!-- Name + handle -->
  <div style="display:flex;flex-direction:column;gap:1px;">
    <div style="display:flex;align-items:center;gap:4px;">
      <span class="x-font" style="font-size:16px;font-weight:700;color:{TEXT_PRIMARY};">{Display Name}</span>
      <!-- Verified badge (if enabled) -->
      <svg width="18" height="18" viewBox="0 0 24 24" fill="{X_BLUE}">
        <path d="M22.25 12c0-1.43-.88-2.67-2.19-3.34.46-1.39.2-2.9-.81-3.91s-2.52-1.27-3.91-.81c-.66-1.31-1.91-2.19-3.34-2.19s-2.67.88-3.33 2.19c-1.4-.46-2.91-.2-3.92.81s-1.26 2.52-.8 3.91c-1.31.67-2.2 1.91-2.2 3.34s.89 2.67 2.2 3.34c-.46 1.39-.21 2.9.8 3.91s2.52 1.26 3.91.81c.67 1.31 1.91 2.19 3.34 2.19s2.68-.88 3.34-2.19c1.39.45 2.9.2 3.91-.81s1.27-2.52.81-3.91c1.31-.67 2.19-1.91 2.19-3.34zm-11.71 4.2L6.8 12.46l1.41-1.42 2.26 2.26 4.8-5.23 1.47 1.36-6.2 6.77z"/>
      
    
    @{handle}
  

Content Area

<div class="x-content" style="flex:1;padding:18px 20px 16px;display:flex;align-items:flex-start;">
  <p class="x-font" style="font-size:20px;font-weight:400;line-height:1.55;color:{TEXT_PRIMARY};margin:0;">
    {Tweet text for this slide}
  </p>
</div>

Content rules:

• Text should feel like a natural tweet — direct, punchy, no corporate speak
• Each slide = one thought / one point
• First slide is the hook (question, bold statement, number)
• Last slide is the CTA (follow, save, share)
• Do NOT repeat the same intro phrase on every slide

Engagement Bar + Slide Counter

<!-- Thin divider above engagement bar -->
<div style="height:1px;background:{DIVIDER};margin:0 20px;"></div>
<!-- Engagement bar -->
<div class="x-engagement" style="display:flex;align-items:center;padding:12px 20px 20px;gap:0;">
  <!-- Reply -->
  <div style="display:flex;align-items:center;gap:6px;flex:1;">
    <svg width="18" height="18" viewBox="0 0 24 24" fill="none" stroke="{ICON_COLOR}" stroke-width="1.8">
      <path d="M21 15a2 2 0 0 1-2 2H7l-4 4V5a2 2 0 0 1 2-2h14a2 2 0 0 1 2 2z"/>
    </svg>
    <span class="x-font" style="font-size:13px;color:{TEXT_MUTED};">{reply_count}</span>
  </div>
  <!-- Repost -->
  <div style="display:flex;align-items:center;gap:6px;flex:1;">
    <svg = = = = = =>
      
    
    {repost_count}
  
  
  
    
      
    
    {like_count}
  
  
  
    
      
    
    {view_count}
  
  
  
    {i+1}/{total}
  

Engagement numbers: Use realistic-looking but fictional numbers. Example: 847 replies, 2.3K reposts, 18.4K likes, 412K views. Vary per slide.

Slide Sequences

Standard Thread (7 slides — default)

#	Type	Content
1	Hook	Bold statement, question, or surprising number that stops the scroll
2	Problem	Pain point or context — why this matters
3	Insight 1	First key point
4	Insight 2	Second key point
5	Insight 3	Third key point
6	Deep dive	Most detailed / surprising revelation
7	CTA	Follow, save, share — clear action

Listicle Thread (5–10 slides)

#	Content
1	Hook — "X coisas que..."
2–N	One item per slide, numbered
Last	CTA

Tutorial Thread (6 slides)

#	Content
1	Hook — what will be taught
2	Why this matters
3–5	Steps 1, 2, 3
6	CTA

All sequences:

• Every slide has the exact same X post header (avatar + name + handle)
• Same background throughout (no alternating dark/light)
• Hook on slide 1 is mandatory
• CTA on last slide is mandatory

---

Slide Architecture

Format

• Aspect ratio: 4:5 (Instagram carousel standard)
• Canvas: 420×525px in HTML preview (exported at 1080×1350px)
• Every slide: same background color (SLIDE_BG), no gradients, no alternating

No Progress Bar

X posts don't have progress bars. Replace with the slide counter pill inside the engagement bar (see above). This is the only slide position indicator.

No Swipe Arrow

X posts don't have decorative arrows. Omit entirely.

---

Preview Wrapper (X Thread Frame)

When displaying in chat, wrap in an X-style post frame:

┌─────────────────────────────────────┐
│  X  [Search...]           🔔 👤     │  ← X app top bar (simplified)
├─────────────────────────────────────┤
│  ← Back    Post                     │  ← Post header bar
├─────────────────────────────────────┤
│  [Swipeable carousel viewport]      │  ← 420×525px
├─────────────────────────────────────┤
│  ● ● ○ ○ ○ ○ ○                     │  ← Dot indicators
└─────────────────────────────────────┘

• Frame width: exactly 420px — never change this, export depends on it
• Carousel viewport: 420×525px
• Top bar: dark or light matching the slide background; X logo (bird/X icon), search bar, bell, profile icons
• Dots: small dot indicators below the viewport, styled to match X's minimalism
• No caption area — X posts don't have Instagram-style captions
• Include pointer-based swipe/drag interaction for preview

Class names to use:

• .x-frame — outer wrapper (420px wide)
• .x-topbar — app top bar
• .carousel-viewport — 420×525px clip area
• .carousel-track — flex row of all slides
• .x-dots — dot indicators
• Each slide: .x-slide

---

Review Flow

Always follow this flow. Never skip to export without approval.

1. Generate the HTML preview first — never jump directly to export
2. Show the preview and ask: "Quais slides precisam de ajuste antes de exportar?"
3. Fix only the mentioned slides — never regenerate the entire carousel unless the direction fundamentally changes
4. Only proceed to export when the user explicitly confirms approval (e.g., "pode exportar", "aprovado", "ok")

---

Exporting Slides as Instagram-Ready PNGs

After the user approves the carousel preview, export each slide as an individual 1080×1350px PNG.

Critical Export Rules

1. Use Python for HTML generation — never use shell scripts with variable interpolation. Always use Path.write_text() or open().write().
2. Embed images as base64 — profile photo must be base64-encoded as data:image/jpeg;base64,... URI. Check actual file format with the file command.
3. Keep the 420px layout width — use Playwright's device_scale_factor to scale up to 1080px output WITHOUT changing the layout viewport.

Install Playwright (only if needed)

python3 -c "import playwright" 2>/dev/null || pip3 install playwright
python3 -c "from playwright.sync_api import sync_playwright; sync_playwright().__enter__().chromium" 2>/dev/null || python3 -m playwright install chromium

Export Script

import asyncio
from pathlib import Path
from playwright.async_api import async_playwright

INPUT_HTML = Path("/path/to/carousel.html")
OUTPUT_DIR = Path("/path/to/output/slides")
OUTPUT_DIR.mkdir(exist_ok=True)

TOTAL_SLIDES = 7  # Update to match your carousel

VIEW_W = 420
VIEW_H = 525
SCALE = 1080 / 420  # = 2.5714...

    async with async_playwright() as p:
        browser = await p.chromium.launch()
        page = await browser.new_page(
            viewport={"width": VIEW_W, "height": VIEW_H},
            device_scale_factor=SCALE,
        )

        html_content = INPUT_HTML.read_text(encoding="utf-8")
        await page.set_content(html_content, wait_until="networkidle")
        await page.wait_for_timeout(3000)  # Wait for Google Fonts to load

        # Hide X frame chrome, show only the slide viewport
        await page.evaluate("""() => {
            document.querySelectorAll('.x-topbar,.x-dots')
                .forEach(el => el.style.display='none');

                clip={: , : , : VIEW_W, : VIEW_H}
            )
            ()

         browser.close()

asyncio.run(export_slides())

Common Export Mistakes to Avoid

Mistake	What goes wrong	Fix
Setting viewport to 1080×1350	Layout reflows — fonts tiny, spacing breaks	Keep viewport at 420×525, use device_scale_factor
Using shell scripts to generate HTML	$ signs and backticks get interpolated	Always use Python for HTML generation
Not waiting for fonts	Headings render in fallback system fonts	wait_for_timeout(3000) after page load
Not hiding X frame chrome	Export includes topbar and dots	Hide .x-topbar,.x-dots
Changing .x-frame width	Entire layout shifts	Always keep at exactly 420px
Using relative path for avatar	Broken image in every context	Always embed as base64 data: URI

Design Principles

1. Authenticity first — every slide must look like a real X post, not a designed graphic
2. Same background throughout — no alternating colors; X threads are visually consistent
3. Large body text — 20px for tweet content ensures readability after Instagram export
4. Profile header on every slide — users scrolling Instagram must always see who posted
5. Fictional but realistic engagement numbers — adds social proof and authenticity
6. Hook-first copy — Slide 1 is the scroll-stopper; every subsequent slide must earn the swipe
7. One thought per slide — each tweet is a standalone idea, not a continuation mid-sentence
8. CTA is always last — follow, save, share — one clear action
9. Iterate fast — show preview, fix specific slides, don't rebuild from scratch
10. Dark or light — never mixed — respect the user's mode choice across all slides
