code-refactor — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited code-refactor (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Infrastructure🔍 偵測到重構需求:
- 檔案:`src/domain/services/order_service.py`
- 問題:檔案長度 342 行(超過 200 行警告閾值)
- 複雜度:圈複雜度 12(超過 10 警告閾值)📊 分析結果:
- `process_order()` 函數 85 行,建議拆分
- 發現 3 處重複邏輯,建議提取
- 識別出 2 個隱藏的 Value Object📋 重構計畫:
1. 提取 `OrderValidator` 類別
2. 提取 `PricingCalculator` 服務
3. 建立 `OrderStatus` Value Object
4. 更新測試確保覆蓋🔧 執行重構:
- [x] 建立 `OrderValidator` 類別
- [x] 遷移驗證邏輯
- [x] 更新測試
- [x] 確認測試通過
- [ ] 提取 `PricingCalculator`
- [ ] ...✅ 重構完成:
- 測試:全部通過(42/42)
- 覆蓋率:85%(+3%)
- 複雜度:8(-4)
- 架構:符合 DDD ✓當偵測到需要重構時,AI 應主動建議:
💡 **重構建議**
偵測到 `order_service.py` 已達 250 行,建議進行模組化:
### 建議拆分方案
| 新檔案 | 內容 | 行數 |
|--------|------|------|
| `order_validator.py` | 訂單驗證邏輯 | ~50 行 |
| `pricing_calculator.py` | 價格計算邏輯 | ~60 行 |
| `order_service.py` | 服務編排 | ~80 行 |
### 預期效益
- ✅ 單一職責原則
- ✅ 更易測試
- ✅ 降低認知負荷
