Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, deepen a chosen module, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
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
# Codebase Design Design **deep modules**: a lot of behaviour behind a small interface, placed at a clean seam, testable through that interface. Use this language and these principles wherever code is being designed or restructured. The aim is leverage for callers, locality for maintainers, and testability for everyone. To survey a whole codebase for deepening opportunities, tell the user to run `/improve-architecture` in Claude linked installs or Cursor, `/supermatt:improve-architecture` from the Claude plugin, `$improve-architecture` in Codex, or `/skill:improve-architecture` in OMP. ## Glossary Use these terms exactly: don't substitute "component," "service," "API," or "boundary." Consistent language is the whole point. **Module**: anything with an interface and an implementation. Deliberately scale-agnostic: a function, class, package, or tier-spanning slice. _Avoid_: unit, component, service. …

How to install
mdr add svyatov/supermatt/codebase-design@sha256:4d330e7e923d8395The line at the top of this page pins the label git:20261018.f19c25a, 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.
