+# Project Fix Plan Skill
+
+## Trigger
+`/project-fix [absolute_path]` or "수정 계획", "개선 플랜"
+
+## Description
+Creates a prioritized action plan from audit findings. Groups fixes by urgency and effort.
+
+## Priority Framework (Eisenhower Matrix for Code)
+
+| | Low Effort | High Effort |
+|---|-----------|-------------|
+| **Critical** | 🔴 DO NOW (Sprint 0) | 🟠 PLAN (Sprint 1-2) |
+| **Important** | 🟡 SCHEDULE (Sprint 1) | ⚪ BACKLOG |
+
+## Categorization Rules
+- **Critical**: Security vulnerabilities, data loss risk, production blockers
+- **Important**: Architecture violations, performance bottlenecks, test gaps
+- **Low Effort**: < 2 hours, single file change
+- **High Effort**: > 1 day, multi-file refactor
+
+## Output Format
+Final deliverable in **Korean (한국어)**.
+
+```markdown
+# [Project Name] Fix Plan
+
+## 🔴 Sprint 0 — 즉시 (이번 주)
+| # | Finding | File | Effort | Agent |
+|---|---------|------|--------|-------|
+| 1 | | | ~Xh | Security |
+
+## 🟠 Sprint 1 — 계획 (다음 2주)
+| # | Finding | Files | Effort | Agent |
+|---|---------|-------|--------|-------|
+
+## 🟡 Sprint 2 — 예정 (이번 달)
+| # | Finding | Scope | Effort | Agent |
+|---|---------|-------|--------|-------|
+
+## ⚪ Backlog — 여유 시 진행
+| # | Finding | Scope | Effort | Agent |
+|---|---------|-------|--------|-------|
+
+## Estimated Total Effort
+- Sprint 0: ~X hours
+- Sprint 1: ~X days
+- Sprint 2: ~X days
+- Backlog: ~X days
+
+## Expected Score Improvement
+| Dimension | Current | After Sprint 0 | After Sprint 1 |
+|-----------|---------|----------------|----------------|
+```
+
+## Brutal Analysis Principles
+- Critical security fixes cannot be pushed to backlog — ever
+- Effort estimates must be realistic for a solo developer
+
+## Claude-Gemini Cross-Debate Protocol
+Priority classification disagreements are debated. Effort estimates are averaged.
