+# Project Health Score Skill
+
+## Trigger
+`/project-health [absolute_path]` or "프로젝트 건강 점수", "헬스 스코어"
+
+## Description
+Calculates a weighted health score (0-100) across all 8 dimensions from the project audit.
+
+## Scoring Weights
+
+| Dimension | Weight | Rationale |
+|-----------|--------|-----------|
+| Security | 20% | Vulnerabilities can kill a product |
+| Architecture | 15% | Foundation determines long-term viability |
+| Code Quality | 15% | Maintainability = team velocity |
+| Testing | 15% | Safety net for changes |
+| Supply Chain | 10% | Legal and security exposure |
+| DevOps | 10% | Deployment reliability |
+| Performance | 10% | User experience |
+| Documentation | 5% | Onboarding and maintenance |
+
+## Score Interpretation
+
+| Range | Grade | Meaning |
+|-------|-------|---------|
+| 90-100 | A | Production-ready, well-maintained |
+| 75-89 | B | Good, minor issues to address |
+| 60-74 | C | Acceptable, significant improvements needed |
+| 40-59 | D | Risky, major issues present |
+| 0-39 | F | Critical, not safe for production |
+
+## Output Format
+Final deliverable in **Korean (한국어)**.

+## Radar Chart Data
+| Dimension | Score | Weight | Weighted |
+|-----------|-------|--------|----------|
+| Security | /10 | 20% | |
+| Architecture | /10 | 15% | |
+| Code Quality | /10 | 15% | |
+| Testing | /10 | 15% | |
+| Supply Chain | /10 | 10% | |
+| DevOps | /10 | 10% | |
+| Performance | /10 | 10% | |
+| Documentation | /10 | 5% | |
+| **Total** | | **100%** | **/100** |
+
+## Trend (if previous audit exists)
+| Dimension | Previous | Current | Delta |
+|-----------|----------|---------|-------|
+
+## Bottom 3 (Biggest Improvement Opportunities)
+1. [Dimension] — [Score] — [Quick Win]
+2. ...
+3. ...
+```
+
+## Brutal Analysis Principles
+- Weighted score must be mathematically correct — no rounding in favor
+- Grade F projects must be called out explicitly
+
+## Claude-Gemini Cross-Debate Protocol
+Score disagreements > 1 point per dimension are debated until consensus.
