Methodology System | 方法論系統

[!WARNING] Experimental Feature / 實驗性功能

This feature is under active development and may change significantly in v4.0. 此功能正在積極開發中，可能在 v4.0 中有重大變更。

Select and manage the active development methodology for the current project. This skill focuses on choosing which methodology to use (SDD, BDD, TDD) and tracking phase progress within the chosen methodology.

選擇並管理當前專案的開發方法論。此技能專注於選擇使用哪種方法論（SDD、BDD、TDD）並追蹤所選方法論內的階段進度。

Related: For navigating development phases and finding the right UDS command at each stage, use /dev-workflow instead.

相關：如需查詢開發階段對應的 UDS 指令，請改用 /dev-workflow。

When to Use /methodology vs /dev-workflow | 何時使用

Scenario	/methodology	/dev-workflow
Choose SDD vs BDD vs TDD	✅	❌
Switch between methodologies	✅	❌
Track current phase progress	✅	❌
Find the right UDS command for a task	❌	✅
Get step-by-step workflow for new feature / bug fix	❌	✅
Navigate 8 development phases	❌	✅

Two Independent Systems / 兩個獨立系統：

• System A: SDD - Spec-Driven Development (AI-era, spec-first)
• System B: Double-Loop TDD - BDD (outer) + TDD (inner) (traditional)

Optional Input: ATDD - Acceptance Test-Driven Development (feeds into either system)

Actions | 動作

Action	Description	說明
(none) / status	Show current phase and checklist	顯示當前階段和檢查清單
switch <id>	Switch to different methodology	切換到不同方法論
phase [name]	Show or change current phase	顯示或變更當前階段
checklist	Show current phase checklist	顯示當前階段檢查清單
skip	Skip current phase (with warning)	跳過當前階段（會有警告）
list	List available methodologies	列出可用方法論
create	Create custom methodology	建立自訂方法論

Available Methodologies | 可用方法論

System	ID	Workflow	工作流程
A: SDD	sdd	/sdd -> Review -> /derive-all -> Implementation	規格優先
B: BDD	bdd	Discovery -> Formulation -> Automation	外部迴圈
B: TDD	tdd	Red -> Green -> Refactor	內部迴圈
Input	atdd	Workshop -> Examples -> Tests	驗收測試驅動

Usage Examples | 使用範例

/methodology                    # Show current status
/methodology switch sdd         # Switch to Spec-Driven Development
/methodology phase green        # Move to GREEN phase (TDD)
/methodology checklist          # Show current phase checklist
/methodology list               # List all available methodologies
/methodology skip               # Skip current phase (with warning)
/methodology create             # Start custom methodology wizard

Configuration | 配置

Methodology settings are stored in .standards/manifest.json:

{
  "methodology": {
    "active": "sdd",
    "available": ["tdd", "bdd", "sdd", "atdd"]
  }
}

Next Steps Guidance | 下一步引導

After /methodology completes, the AI assistant should suggest based on the selected methodology:

方法論已設定。建議下一步 / Methodology configured. Suggested next steps:

• SDD 方法論 → 執行 /sdd 建立規格 ⭐ Recommended / 推薦 — SDD → Run /sdd to create spec
• BDD 方法論 → 執行 /bdd 開始場景探索 — BDD → Run /bdd to start discovery
• TDD 方法論 → 執行 /tdd 開始紅綠重構 — TDD → Run /tdd to start Red-Green-Refactor
• ATDD 方法論 → 執行 /atdd 定義驗收條件 — ATDD → Run /atdd to define AC
