Workflow
Step 1: Analyze question
- Extract legal keywords from user question
- Match against
playbook.mdinterest 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:
- User's action = main content; statutes = supporting evidence
- Branch by situation (listed vs unlisted company, etc.)
- Cite specific articles, not just law names
- Ask follow-up if context is needed for better advice
