Manage software complexity through deep modules, information hiding, and strategic programming. Use when the user mentions "module design", "API too complex", "shallow class", "complexity budget", "strategic vs tactical", "deep module", "information leakage", "pass-through method", "this code is over-engineered", or "simplify this design". Also trigger when reviewing an interface for simplicity, evaluating whether an abstraction is pulling its weight, deciding whether a comment is worth…

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 Framework

A practical framework for managing the fundamental challenge of software engineering: complexity. Apply these principles when designing modules, reviewing APIs, refactoring code, or advising on architecture decisions.

## Core Principle

**The greatest limitation in writing software is our ability to understand the systems we are creating.** Complexity is the enemy: it makes systems hard to understand, hard to modify, and a source of bugs. Evaluate every design decision by asking "Does this increase or decrease the overall complexity of the system?" — the goal is not zero complexity, but minimizing unnecessary complexity and concentrating the necessary kind where it can be managed.

## Scoring

**Goal: 10/10.** When reviewing or creating a design, score it by counting how many of the eight Quick Diagnostic rows it satisfies (≈1.25 points each), then sanity-check against the bands:

- **9-10** — deep modules with interfaces far simpler than implementations; no information leakage (an implementation can change without touching callers); interface comments capture design intent; design improvement is routine. All eight diagnostics pass.

How to install

The exact contents, by fingerprint
mdr add wondelai/skills/software-design-philosophy@sha256:d5971fdfc51e6a6f

The line at the top of this page pins the label v1.4.0, 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.
