用于设计深模块的共享词汇。适用于用户想设计或改进模块接口、寻找深化机会、决定 seam 放在哪里、让代码更容易测试或更适合 AI 导航，或其他技能需要深模块词汇时。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 代码库设计 设计 **deep modules**：把大量行为放在小 interface 之后，把 interface 放在清晰 seam 上，并通过该 interface 测试。凡是在设计或重构代码时，都使用这套语言和原则。目标是给 callers 带来 leverage，给 maintainers 带来 locality，并让每个人都更容易测试。 ## 术语表 准确使用这些术语，不要替换成 "component"、"service"、"API" 或 "boundary"。一致语言就是重点。 **Module** - 任何拥有 interface 和 implementation 的东西。它故意不限定尺度：function、class、package，或跨层 slice 都可以。_Avoid_: unit, component, service. **Interface** - caller 为了正确使用 module 必须知道的一切：type signature，以及 invariants、ordering constraints、error modes、required configuration 和 performance characteristics。_Avoid_: API, signature（太窄，只指 type-level surface）。 **Implementation** - module 内部的代码体。它不同于 **Adapter**：一个东西可以是小 adapter 但有大 implementation（Postgres repo），也可以是大 adapter 但 implementation 很小（in-memory fake）。讨论 seam 时说 adapter；其他时候说 implementation。 **Depth** - interface 上的 leverage：caller（或 test）每学习一单位 interface，就能触达多少行为。大量行为藏在小 interface 后面时，module 是 **deep**；interface 几乎和 implementation 一样复杂时，module 是 **shallow**。 **Seam**（Michael Feathers）- 你可以在不编辑当前位置的情况下改变行为的地方；也就是 module 的 interface 所在的 *location*。seam 放在哪里是独立设计决策，不同于 seam 后面放什么。_Avoid_: boundary（它和 DDD bounded context 过载）。 …

How to install
mdr add vinvcn/mattpocock-skills-zh-cn/codebase-design@sha256:7f3980323c33e69bThe line at the top of this page pins the label git:20261008.5be0dc1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
