Forward Derivation | 正向推演
Generate derived artifacts (BDD scenarios, TDD skeletons, ATDD tables) from approved SDD specifications.
從已批准的 SDD 規格生成衍生工件（BDD 場景、TDD 骨架、ATDD 表格）。
Subcommands | 子命令
Subcommand Description Output
all
Generate BDD + TDD (default) .feature
- .test.*
bdd
Generate BDD scenarios only .feature
tdd
Generate TDD skeletons only .test.*
atdd
Generate ATDD test tables .md (Markdown tables)
Workflow | 工作流程
-
Read Spec - Analyze the input SPEC-XXX.md file | 分析規格檔案
-
Extract AC - Parse all Acceptance Criteria | 解析所有驗收條件
-
Generate Artifacts - Create BDD/TDD/ATDD outputs | 產生衍生工件
-
Verify - Ensure 1:1 mapping between AC and generated items | 驗證一對一對應
Anti-Hallucination Rules | 防幻覺規則
Rule Description 說明
1:1 Mapping Every AC has exactly one test/scenario 每個 AC 對應一個測試
Traceability All artifacts reference Spec ID and AC ID 所有工件引用規格與 AC 編號
No Invention Do not add scenarios not in the spec 不新增規格外的場景
Generated Artifact Tags | 產生工件標籤
Tag Meaning 含義
[Source]
Direct content from spec 直接來自規格
[Derived]
Transformed from source 從來源轉換
[Generated]
AI-generated structure AI 產生的結構
[TODO]
Requires human implementation 需人工實作
Usage | 使用方式
/derive all specs/SPEC-001.md - Derive BDD + TDD | 推演 BDD + TDD /derive bdd specs/SPEC-001.md - Derive BDD scenarios only | 僅推演 BDD 場景 /derive tdd specs/SPEC-001.md - Derive TDD skeletons only | 僅推演 TDD 骨架 /derive atdd specs/SPEC-001.md - Derive ATDD tables | 推演 ATDD 表格
Next Steps Guidance | 下一步引導
After /derive completes, the AI assistant should suggest:
測試工件已產生。建議下一步 / Test artifacts generated. Suggested next steps:
-
執行 /tdd 開始紅綠重構循環 — Start Red-Green-Refactor cycle
-
執行 /bdd 細化 Gherkin 場景 — Refine Gherkin scenarios
-
檢查產生的 [TODO] 標記並補齊實作 — Review [TODO] markers and fill in implementations
