Workflow | 工作流程
- Assess - Identify code to refactor, evaluate test coverage
- Decide - Run decision tree (refactor vs. rewrite) if needed
- Select strategy - Choose appropriate strategy based on scope and risk
- Execute - Follow step-by-step workflow with safety checks
- Verify - Run tests to confirm behavior is preserved
Usage Examples | 使用範例
User: /refactor src/legacy-auth/
AI: Analyzing src/legacy-auth/...
Test coverage: 23% — recommending safety-first approach.
Suggested strategy: Characterization Tests + Preparatory Refactoring
User: /refactor decide
AI: Let me help you decide whether to refactor or rewrite.
Question 1: Is the code currently working in production? [Y/N]
Next Steps Guidance | 下一步引導
After /refactor completes, the AI assistant should suggest:
重構完成。建議下一步 / Refactoring complete. Suggested next steps: - 執行 /checkin 通過品質關卡 ⭐ Recommended / 推薦 — Pass quality gates - 執行 /coverage 確認重構後覆蓋率不下降 — Verify coverage not decreased - 執行 /commit 提交重構變更 — Commit the refactoring changes
