Code Card News Generator

코드 설명용 카드 뉴스를 생성하는 스킬입니다. 제목 카드와 함수/개념 설명 카드를 자동으로 만듭니다.

When to Use

Use this skill when user requests:

• "코드 설명 카드 만들어줘"
• "React Hook 설명 카드 생성해줘"
• "코드 튜토리얼 카드 뉴스 만들어줘"
• Any request for code tutorial/explanation cards

Core Workflow

Step 1: Get Topic and Content from User

Ask user for:

• Topic (주제): What library/framework/concept (e.g., "React Router Hooks")
• Functions/Concepts: List of items to explain (e.g., "useNavigate, useParams, useLocation")

Example conversation:

Claude: 어떤 주제로 코드 카드를 만들까요?
User: React Router Hooks

Claude: 어떤 Hook들을 설명할까요?
User: useNavigate, useParams, useLocation

Step 2: Generate Content

For each function/concept, create:

1. Description (한국어 설명): Brief explanation in Korean/English
2. Code Example: Working code snippet
3. Explanation: What the code does

Example:

1. useNavigate
Description: It's used for programmatic navigation, allowing you to redirect users or change routes without needing to render a <Link> component.
Code:
const navigate = useNavigate();

const handleClick = () => {
  navigate('/home');
};
Explanation: In this example, calling handleClick will navigate the user to the /home route.

Step 3: Auto-Generate Cards

Use this command:

python3 auto_code_generator.py \
  --topic "React Router Hooks" \
  --output-dir ./output \
  --base-filename "react_router" << 'EOF'
TITLE: React|Router|Hooks

1. useNavigate
Description: It's used for programmatic navigation, allowing you to redirect users or change routes without needing to render a <Link> component.
Code:
const navigate = useNavigate();

const handleClick = () => {
  navigate('/home');
};
Explanation: In this example, calling handleClick will navigate the user to the /home route.

2. useParams
Description: useParams is used to access dynamic parameters from the current URL.
Code:
const { id } = useParams();

console.log(id); // Outputs the 'id' from URL
Explanation: If the route is /user/:id and you visit /user/123, useParams will return { id: '123' }.
EOF

The script will generate:

• react_router_00_title.png - Title card
• react_router_01.png - useNavigate explanation
• react_router_02.png - useParams explanation

Step 4: Provide Download Links

After generation, show user:

✅ 코드 카드 3장이 생성되었습니다!

Input Format

Title Card

TITLE: Part1|Part2|Part3

Parts separated by | will alternate colors (white/pink). Example:

• React|Router|Hooks → "React" (white), "Router" (pink), "Hooks" (white)

Optional subtitle:

TITLE: React|Router|Hooks
SUBTITLE: Navigation Made Easy

Explanation Cards

1. functionName
Description: Korean or English description...
Code:
code line 1
code line 2
code line 3
Explanation: Additional explanation about what the code does...

2. nextFunction
Description: ...
Code:
...
Explanation: ...

Important:

• Each card starts with a number (1., 2., etc.)
• Description: - The main explanation
• Code: - Code example (starts on next line)
• Explanation: - Optional additional context

Content Guidelines

Good Code Example

1. useState
Description: useState is a Hook that lets you add state to functional components.
Code:
const [count, setCount] = useState(0);

setCount(count + 1);
Explanation: This creates a state variable 'count' with initial value 0.

✓ Clear function name ✓ Concise description ✓ Simple, working code ✓ Helpful explanation

Bad Code Example

1. This is a very long function name that explains everything
Description: This is a very long description that goes on and on explaining every single detail about how this function works in various scenarios and edge cases...
Code:
// 50 lines of complex code
...

✗ Too verbose ✗ Code too long/complex ✗ Won't fit in 1080x1080 canvas

Manual Single Card Creation

Create Title Card Only

python3 generate_code_card.py title \
  --title "React|Router|Hooks" \
  --subtitle "Navigation Made Easy" \
  --output ./title.png

Create Explanation Card Only

python3 generate_code_card.py explain \
  --number "1" \
  --function "useNavigate" \
  --description "It's used for programmatic navigation..." \
  --code "const navigate = useNavigate();" \
  --explanation "This allows navigation without Link component." \
  --output ./card_01.png

Example Topics

• React Hooks (useState, useEffect, useContext)
• React Router Hooks (useNavigate, useParams, useLocation)
• Array Methods (map, filter, reduce)
• Python Built-ins (enumerate, zip, lambda)
• CSS Flexbox (flex-direction, justify-content, align-items)
• Git Commands (commit, push, pull, merge)

Tips for Good Cards

1. Keep It Simple: One concept per card
2. Code Length: Max 5-7 lines of code
3. Use Comments: Add helpful comments in code
4. Highlight Keywords: Important terms will be auto-highlighted
5. Test Code: Make sure code examples actually work

Error Handling

If text overflows:

• Shorten description
• Reduce code lines
• Simplify explanation
• Use more concise language

Example Workflow

User request: "React Router Hooks 설명 카드 3개 만들어줘"

Claude response:

1. Confirm: "React Router Hooks에 대한 코드 카드를 만들겠습니다. useNavigate, useParams, useLocation을 설명하겠습니다."
2. Generate content for 3 hooks
3. Run auto_code_generator.py with heredoc
4. Provide download links

Total time: ~1 minute for 4-card series (1 title + 3 explanations)
