<!-- DEPRECATION NOTICE (XSPEC-086 Phase 4, 2026-04-28):
ATDD lifecycle orchestration (5-phase: WORKSHOP→DISTILLATION→DEVELOPMENT→DEMO→DONE,
INVEST validation, AC→Gherkin conversion, RED/GREEN execution, PO sign-off gates) relocated to
adoption layer (XSPEC-095, 2026-04-28). This Skill retains: INVEST criteria table, ATDD cycle
diagram, Gherkin AC format, Three Amigos structure.
For enforced lifecycle execution, use your adoption layer's toolchain.

ATDD Assistant | ATDD 助手
Guide through the Acceptance Test-Driven Development (ATDD) workflow for defining and validating user stories.
引導驗收測試驅動開發（ATDD）流程，用於定義和驗證使用者故事。
ATDD Cycle | ATDD 循環
WORKSHOP ──► DISTILLATION ──► DEVELOPMENT ──► DEMO ──► DONE
^ │ │
└──────────────────────────────┴──────────────┘
(Refinement needed)
Workflow | 工作流程
1. WORKSHOP - Define AC | 定義驗收條件
PO presents user story, team asks clarifying questions, define acceptance criteria together.
2. DISTILLATION - Convert to Tests | 轉換為測試
Convert AC to executable test format, remove ambiguity, get PO sign-off.
3. DEVELOPMENT - Implement | 實作
Run acceptance tests (should fail initially), use BDD/TDD for implementation, iterate until all pass.
4. DEMO - Present | 向利害關係人展示
Show passing acceptance tests, demonstrate working functionality, get formal acceptance.
5. DONE - Complete | 完成
PO accepted, code merged, story closed.
INVEST Criteria | INVEST 準則
| Criterion | Description | 說明 | |-----------|-------------|------| | Independent | Can be developed separately | 可獨立開發 | | Negotiable | Details can be discussed | 可協商細節 | | Valuable | Delivers business value | 提供商業價值 | | Estimable | Can estimate effort | 可估算工作量 | | Small | Fits in one sprint | 一個 Sprint 可完成 | | Testable | Has clear acceptance criteria | 有明確驗收條件 |
User Story Format | 使用者故事格式
As a [role],
I want [feature],
So that [benefit].
### Acceptance Criteria
- Given [context], when [action], then [result]
Usage | 使用方式
/atdd - Start interactive ATDD session | 啟動互動式 ATDD 會話
/atdd "user can reset password" - ATDD for specific feature | 針對特定功能
/atdd US-123 - ATDD for existing user story | 處理現有使用者故事
Next Steps Guidance | 下一步引導
After /atdd completes, the AI assistant should suggest:
驗收測試已定義。建議下一步 / Acceptance tests defined. Suggested next steps:
- 執行
/sdd建立規格文件 ⭐ Recommended / 推薦 — Create a specification document- 執行
/bdd將 AC 轉為 Gherkin 場景 — Convert AC to Gherkin scenarios- 執行
/tdd直接實作驗收測試 — Implement acceptance tests directly
