writing-plans

Write implementation plans - when a spec or clear requirement exists and multi-step work has not started: decompose the design into bite-sized tasks a zero-context engineer can execute (exact file paths, complete code, TDD steps, expected output), save under the feature directory plan/ subdir, hand off to executing-plans. Usually invoked by requirement-analysis after spec approval. / 编写实施计划——当已有 spec 或明确需求、准备开始多步骤开发任务、但尚未动代码时使用。把设计拆解为零上下文工程师也能执行的 bite-sized 任务（精确文件路径、完整代码、TDD 步骤、预期输出），落盘特性目录的 plan/ 子目录并交接 executing-plans 执行。通常由 requirement-analysis 在 spec 获批后调用；也可对既有 spec/需求单独触发。
