Card News Generator v2 - Auto Mode (V2)

Creates beautiful 600x600 card news series for social media with background image support. User can provide topic, colors, and optional background images - Claude handles content generation and multi-card creation automatically.

When to Use

Use this skill when user requests:

• "카드 뉴스 만들어줘"

• "주제로 카드 시리즈 만들어줘"

• "인스타용 카드 생성해줘"

• Any request for visual card content

Core Workflow - AUTO MODE

This is the PRIMARY workflow when users request card news:

Step 1: Get Topic, Colors, and Optional Background Images from User

Ask user for:

• Topic (주제): What the card series is about

• Background RGB (배경색): e.g., 245,243,238 (optional, default: beige)

• Background Images (배경 이미지, 선택사항): Path to folder containing images

Example conversation (Solid Color):

Claude: 어떤 주제로 카드 뉴스를 만들까요? User: Z세대의 특징에 대해서

Claude: 배경색을 선택해주세요 (RGB 형식, 예: 245,243,238) 추천 색상: • 베이지: 245,243,238 • 핑크: 255,229,229 • 민트: 224,244,241 User: 245,243,238

Example conversation (With Background Images):

Claude: 어떤 주제로 카드 뉴스를 만들까요? User: 여행 팁 5가지

Claude: 배경 이미지를 사용하시겠어요? (사용하려면 이미지 폴더 경로 입력) User: /path/to/travel-images

Claude: 오버레이 불투명도를 선택하세요 (0.0-1.0, 기본값 0.5) 높을수록 어둡게 처리되어 텍스트가 더 잘 보입니다. User: 0.6

Step 2: Generate Card Content

Create 5-7 cards about the topic. Format output as:

1. [제목] [설명 2-3줄]

2. [제목] [설명 2-3줄]

3. [제목] [설명 2-3줄]

CRITICAL Content Guidelines:

• Title: Maximum 20 characters (including spaces)

• Content: Maximum 60 characters (including spaces)

• Keep it concise to fit 600x600 canvas

• Use simple, impactful language

• Each card should convey ONE key point

Step 3: Auto-Generate Cards

Option A: Solid Color Background

Use this command to create all cards with solid color background:

python auto_generator.py
--topic "Z세대의 특징"
--bg-color "#f5f3ee"
--text-color "#1a1a1a"
--output-dir /mnt/user-data/outputs
--base-filename "zgen" << 'EOF'

1. 디지털 네이티브 태어날 때부터 디지털 환경에 익숙

2. 개인화 중시 나만의 개성과 취향을 중요시

3. 소통 방식 텍스트보다 영상 이모티콘으로 감정 표현 EOF

Option B: Background Images (V2 Feature)

Use this command to create cards with background images:

python auto_generator.py
--topic "여행 팁"
--output-dir /mnt/user-data/outputs
--base-filename "travel"
--image-folder /path/to/travel-images
--overlay-opacity 0.6 << 'EOF'

1. 짐 싸기 팁 최소한의 짐으로 가볍게 여행하기

2. 현지 음식 맛집 찾는 나만의 방법

3. 교통 수단 대중교통 활용 팁과 노하우 EOF

Important Notes:

• Images in the folder must be sorted alphabetically/numerically (e.g., 01.jpg , 02.jpg , 03.jpg )

• Image count should match card count

• If fewer images than cards, remaining cards will use solid color background

• Supported formats: .jpg , .jpeg , .png , .webp , .bmp

• Text automatically changes to white when using background images

The script will automatically:

• Parse the numbered content

• Load background images from the folder (in sorted order)

• Apply dark overlay for better text visibility

• Create individual cards with proper text wrapping

• Save as travel_01.png , travel_02.png , etc.

Step 4: Provide Download Links

After generation, show user:

✅ 카드 뉴스 5장이 생성되었습니다!

RGB to Hex Conversion

Always convert RGB to hex for scripts:

RGB 245,243,238 → Hex #f5f3ee

hex_color = '#{:02x}{:02x}{:02x}'.format(245, 243, 238)

Recommended Colors (RGB Format)

Show users these options:

• Warm beige: 245,243,238 → #f5f3ee

• Soft pink: 255,229,229 → #ffe5e5

• Mint green: 224,244,241 → #e0f4f1

• Lavender: 232,224,245 → #e8e0f5

• Peach: 255,232,214 → #ffe8d6

• Sky blue: 227,242,253 → #e3f2fd
