codebase-design skillA

codebase-design is agent-read markdown (skill) from aethrox/doctrine: Module design discipline from John Ousterhout's A Philosophy of Software Design, depth as the metric (a lot of functionality behind a simple interface), information hiding vs. leakage, the concrete red flags that mark a shallow module, and comparing at least two designs before committing. Use when designing a new module or class, deciding where an interface boundary (seam) should go, reviewing a design for unnecessary complexity, or asking whether something should be split or merged..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add aethrox/doctrine/codebase-design@git:20260809.2a45dbb
Exact content
mdr add aethrox/doctrine/codebase-design@sha256:e0a14420e23c6500

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
