# Development Workflow Guide | 開發工作流程指南

> **Language**: English | [繁體中文](../../locales/zh-TW/skills/dev-workflow-guide/SKILL.md)

Map your current software development phase to the right UDS commands and skills. Get instant guidance on which tools to use at each stage of development.

將你目前的軟體開發階段對應到正確的 UDS 指令與技能。即時了解在開發的每個階段應該使用哪些工具。

> **Related**: To choose or switch between development methodologies (SDD, BDD, TDD), use `/methodology` instead.
>
> **相關**：如需選擇或切換開發方法論（SDD、BDD、TDD），請改用 `/methodology`。

## Common Scenarios | 常見場景

### Scenario 1: New Feature (Greenfield) | 新功能開發

Recommended flow for building a new feature from scratch:

從零開始建立新功能的推薦流程：

```
/brainstorm → /requirement → /sdd → /derive → /tdd → /checkin → /commit
```

| Step | Command | What to Do | 做什麼 |
|------|---------|-----------|--------|
| 1 | `/brainstorm` | Explore ideas and approaches | 探索想法與方法 |
| 2 | `/requirement` | Write user stories (INVEST criteria) | 撰寫使用者故事 |
| 3 | `/sdd` | Create specification document | 建立規格文件 |
| 4 | `/derive` | Generate test skeletons from spec | 從規格產生測試骨架 |
| 5 | `/tdd` | Implement with Red-Green-Refactor | 用紅綠重構循環實作 |
| 6 | `/checkin` | Verify quality gates | 驗證品質關卡 |
| 7 | `/commit` | Create conventional commit | 建立規範化提交 |

### Scenario 2: Bug Fix | 修復錯誤

Recommended flow for fixing bugs in existing code:

修復既有程式碼錯誤的推薦流程：

```
/discover → /reverse → /tdd → /checkin → /commit
```

| Step | Command | What to Do | 做什麼 |
|------|---------|-----------|--------|
| 1 | `/discover` | Assess affected area health | 評估受影響區域健康度 |
| 2 | `/reverse` | Understand existing code structure | 理解現有程式碼結構 |
| 3 | `/tdd` | Write failing test, then fix | 先寫失敗測試，再修復 |
| 4 | `/checkin` | Verify quality gates | 驗證品質關卡 |
| 5 | `/commit` | Create conventional commit | 建立規範化提交 |

### Scenario 3: Refactoring | 重構

Recommended flow for code refactoring:

程式碼重構的推薦流程：

```
/discover → /reverse → /coverage → /refactor → /checkin → /commit
```

| Step | Command | What to Do | 做什麼 |
|------|---------|-----------|--------|
| 1 | `/discover` | Assess project health and risks | 評估專案健康度與風險 |
| 2 | `/reverse` | Document current behavior | 記錄目前行為 |
| 3 | `/coverage` | Ensure test safety net exists | 確保測試安全網存在 |
| 4 | `/refactor` | Apply refactoring strategies | 套用重構策略 |
| 5 | `/checkin` | Verify quality gates | 驗證品質關卡 |
| 6 | `/commit` | Create conventional commit | 建立規範化提交 |

## Usage | 使用方式

```bash
/dev-workflow                    # Show full phase overview
/dev-workflow planning           # Get Phase I guidance
/dev-workflow testing            # Get Phase II guidance
/dev-workflow new-feature        # Get new feature workflow
/dev-workflow bug-fix            # Get bug fix workflow
/dev-workflow refactoring        # Get refactoring workflow
```

### Supported Arguments | 支援的參數

| Argument | Description | 說明 |
|----------|-------------|------|
| `planning` | Phase I: Planning & Design | 需求與設計 |
| `testing` | Phase II: Test-Driven Development | 測試驅動開發 |
| `implementation` | Phase III: Implementation | 程式碼開發 |
| `quality` | Phase IV: Quality Gates | 品質保證 |

## Workflow Behavior | 工作流程行為

When invoked:

1. **No arguments**: Display the full phase overview table and ask which phase the user is in
2. **Phase argument**: Show detailed guidance for that specific phase, including all relevant commands with examples
3. **Scenario argument**: Show the recommended step-by-step workflow for that scenario

The skill reads from [workflow-phases.md](./workflow-phases.md) for detailed phase information.

呼叫時：

1. **無參數**：顯示完整的階段總覽表，詢問使用者目前在哪個階段
2. **階段參數**：顯示該階段的詳細指引，包含所有相關指令與範例
3. **場景參數**：顯示該場景的推薦逐步工作流程

## Next Steps Guidance | 下一步引導

After `/dev-workflow` completes, the AI assistant should suggest based on user's situation:

> **工作流程已顯示。建議下一步 / Workflow displayed. Suggested next steps:**
> - 新功能開發 → 執行 `/brainstorm` 探索想法 — New feature → Run `/brainstorm` to explore ideas
> - 修復錯誤 → 執行 `/discover` 評估受影響區域 — Bug fix → Run `/discover` to assess affected area
> - 重構程式碼 → 執行 `/discover` 評估健康度 — Refactoring → Run `/discover` to assess health
> - 遺留系統 → 執行 `/reverse` 進行系統考古 — Legacy system → Run `/reverse` for system archeology
