Apply John Ousterhout-inspired software design rules when reducing complexity, designing module boundaries, or reviewing APIs and abstractions.
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
# A Philosophy of Software Design Skill Use this skill when a task involves module design, API design, information hiding, abstraction depth, cognitive load, or refactoring shallow interfaces. Before making design or code decisions, read and apply [a-philosophy-of-software-design.mini.md](a-philosophy-of-software-design.mini.md). Use [a-philosophy-of-software-design.md](a-philosophy-of-software-design.md) only as a deeper reference when the mini rules are not enough for the current design tradeoff.

How to install
mdr add aicodedecode/awesome-muse-skills/a-philosophy-of-software-design@sha256:c34604b6c55d357fThe line at the top of this page pins the label git:20260927.806f3e1, 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.
