測試案例產生器（Test Case Writer）

在流程的位置

prd-writer / enterprise-prd-writer  ──→  AC（Given/When/Then + Edge Case）
                                              ↓
                                    【test-case-writer】← 展開成可執行測試案例

                                          QA 執行 / 自動化

分工界線：

Skill	負責	不負責
enterprise-prd-writer	定義需求與 AC	不展開逐條測試步驟
test-case-writer	把 AC 展開成可執行測試案例	不改需求、不寫測試程式碼

如果輸入的 PRD 沒有 AC，先提醒使用者「這份缺 AC，測試案例會不完整」，再就現有資訊盡量產出，並標出哪些是因缺 AC 而假設的。

核心原則

1. 每條 AC 至少展開成一組正常 + 邊界 + 異常

一條 Given/When/Then 不等於一個測試案例。它至少要拆成：

正常路徑（Happy Path）：條件成立，預期結果發生
邊界值（Boundary）：剛好在門檻上、門檻 ±1、最小/最大值
異常路徑（Negative）：條件不成立、輸入非法、前置失敗
