Card News (카드뉴스) Pipeline 🐧

Topic → 5-slide plan → image generation → JPG conversion → caption → Instagram upload.

Workflow

1. Content Planning

Given a topic, plan 5 slides:

| Slide | Role | Content | |-------|------|---------| | 1 | Hook | Bold question or surprising statement to stop scrolling | | 2 | Problem/Context | Why this matters | | 3 | Core insight | Key information or explanation | | 4 | Detail/Example | Supporting evidence or practical example | | 5 | CTA/Summary | Takeaway + follow/save prompt + 🐧 branding |

2. Image Generation (nano-banana-pro)

Generate each slide as 1024×1024 PNG using the nano-banana-pro skill:

# Path may vary based on installation
uv run /skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "" --filename "cardnews-TOPIC-N.png" --resolution 1K

Prompt structure per slide:

Include exact Korean text to render (in quotes)

Specify: dark background, neon cyan (#00FFFF) accent text, white primary text

Include 🐧 penguin emoji on slide 5

No English unless the topic requires it

See references/design-guide.md for visual style rules.

3. PNG → JPG Conversion

Instagram rejects PNG frequently. Always convert:

python3 {baseDir}/scripts/convert_jpg.py cardnews-topic-1.png cardnews-topic-2.png ...

Outputs *-ig.jpg files (1024×1024, quality 92).

4. Caption Writing

Write an Instagram caption in Korean:

1-2 line hook matching slide 1

3-5 hashtags (mix of broad + niche)

End with CTA: "저장하고 나중에 다시 보세요 📌"

5. Instagram Upload

Use the browser-based upload flow documented in TOOLS.md ("인스타그램 게시물 업로드" section). Upload all 5 JPG files as a carousel post.
