executing-plans

Execute implementation plans - when a written plan from writing-plans exists (plan/ split-file layout: index.md + tasks/ + progress.yaml; legacy single-file plans read as-is — under the feature directory in .spec-dev/): the main thread executes task-by-task in an isolated worktree (TDD + per-task commits + spec self-check), then orchestrates multi-dimension adversarial code review and matrix-driven acceptance. Not for improvised changes without a written plan. / 执行实施计划——当已有 writing-plans 产出的实施计划（.spec-dev/ 特性目录下 plan/ 的分文件形态：index.md + tasks/ + progress.yaml；存量单文件计划按原样读取）、准备动手实现时使用。主线程在隔离 worktree 中逐任务执行（TDD + 每任务提交 + spec 自检），全部完成后编排多维对抗代码审查（code-reviewer 子代理不写码、仅分析与复跑验证），并按验收矩阵触发 acceptance-qa 验收，最终合并总结。不适用于没有书面计划的即兴改动。
