Scripts

scripts/
├── law_search.sh   → Search laws by keyword
├── law_detail.sh   → Statute text by law ID
├── case_search.sh  → Court case search
└── life_law.sh     → Everyday legal info search

Workflow

Step 1: Analyze question

• Extract legal keywords from user question
• Match against playbook.md interest areas
• Decide strategy: statute-focused? case-focused? combined?

Step 2: Search statutes

• law_search.sh "keyword" → list of relevant laws

Step 3: Fetch statute text (if needed)

• law_detail.sh [law_id] → specific articles

Step 4: Search cases

• case_search.sh "keyword" → relevant court decisions

Step 5: Everyday legal info (optional)

• life_law.sh "keyword" → plain-language legal guide

Step 6: Structured response using template

Output Template

Action-first structure: lead with what to DO, then back it up with law.

## ⚖️ [Topic]

### 📋 Core Answer
[1-2 sentence conclusion — what the user needs to know]

### 🚶 What To Do (practical steps)
1. [Concrete action step] — with conditions/branches if needed
2. [Next step]
3. [Final step]
※ [Situation-specific branch: "If X, then A; if Y, then B"]

### 📖 Legal Basis
**[Law Name]** Art. X (Effective YYYY.MM.DD)
> ① Original text...
> → Plain language: [simplified explanation]

**[Related Law]** Art. Y (if applicable)
> ...

### ⚖️ Related Case (if relevant)
**[Case Number]** ([Court], YYYY.MM.DD)
> Key point: [one-line holding]

### 🔗 References
- [Statute](https://www.law.go.kr/...)

⚠️ Reference only — not legal advice. Consult an attorney for important decisions.

Principles:

1. User's action = main content; statutes = supporting evidence
2. Branch by situation (listed vs unlisted company, etc.)
3. Cite specific articles, not just law names
4. Ask follow-up if context is needed for better advice

2. Currency: Based on current law, but recent amendments may have delay.
3. Format: law.go.kr returns JSON; data.go.kr returns XML → each needs parser.
4. Priority: law.go.kr JSON first → fallback to data.go.kr XML.
5. Encoding: URL-encode query parameters.

🔧 Setup

법제처 국가법령정보 API (주 API)

1. open.law.go.kr 회원가입
2. OC 코드 발급 (이메일 @ 앞부분)
3. mkdir -p ~/.config/law-go-kr && echo '{"oc":"YOUR_OC"}' > ~/.config/law-go-kr/credentials.json

data.go.kr 판례 API (보조)

1. data.go.kr 회원가입 → 인증키 복사
2. mkdir -p ~/.config/data-go-kr && echo "YOUR_KEY" > ~/.config/data-go-kr/api_key

법제처 API 미등록 시에도 web_search 폴백으로 법령 기본 검색 가능합니다.
