Use when you (a coding/execution agent) are designing, building, or testing actual code and want to apply established engineering theories well —— 当你(执行 agent)在动手设计 / 开发 / 测试代码、想遵循 DDD / SDD / TDD / OOP 的最佳实践与品味时:怎么给领域建模(bounded context / aggregate / 不变式)、怎么写好类(SOLID / 四柱 / 组合优于继承)、怎么 spec-first(契约即 SSOT)、怎么 test-first(红绿铁律 / constraint parity)。核心是工程心智模型 + 哲学 + 艺术品味 + 方法论,叠加 no-silent-failure / spec 不漂移 / 无 idle wrapper 等红线。五条共享根:不变式即锚 / 契约即 SSOT / 组合优于包装 / 分层思维 / 证据优于声称。Triggers: 要设计一个模块 / 给领域建模 / 划 bounded context / 写类纠结继承还是组合 / 要不要先写 spec / 先写测试还是先写实现 / 这个抽象值不值 / 怎么躲开贫血模型或 god class。Do NOT use when 你在决定该编排什么 / 怎么派发(master-orchestrator-guide)、怎么把目标切成任务 DAG(slicing-goals-into-dags)、把一个任务迭代优化到验收的循环形状本身(dev-as-ml-loop)、怎么用 ccm 写 board(using-ccm)、workflow 脚本怎么写(authoring-workflows)。
