README

Excerpt

模块化设计六原则

经典软件工程设计原则在 AI 协作场景下的现代化清单。用作新模块设计、重构、代码审查时的对照表，不替代具体执行 skill。

触发场景

编写新模块、新服务、新接口
用户说"设计"、"拆分模块"、"评审"、"重构"
/review、/new-feature、/optimize、/design 命令在设计阶段
评估技术债时对照原则定位坏味道

六原则速查表

#	原则	一句话	衡量指标	详细案例
1	模块大小适中	单文件控制在职责边界内	行数/职责数	引用 size-check
2	减少调用深度	调用链尽量 ≤ 3 层	栈深度	modularity.md#调用深度
3	多扇入，少扇出	被复用 > 主动依赖	依赖数/被依赖数	modularity.md#扇入扇出
4	接口边界清晰	入参/出参/异常统一	统一响应包装	modularity.md#边界清晰
5	作用域内聚	改 A 不波及 B	跨模块副作用	引用 refactor-safety
6	功能可预测	同输入→同输出	幂等/无副作用/可测	predictability.md
