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.mdfile | 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 |
|---|---|---|
