Apply fundamental coding principles (SOLID, DRY, KISS) and structure projects for maintainability with clean architecture and separation of concerns. Use when refactoring, reviewing patterns, setting up project structure, or organizing modules.
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.

# Core Principles & Code Organization > **Purpose**: Fundamental principles guiding production code development and project structure. > **Focus**: SOLID, DRY, KISS, design patterns, project organization. --- ## When to Use This Skill - Reviewing code for SOLID principle compliance - Refactoring code for maintainability - Choosing appropriate design patterns - Teaching or evaluating engineering standards - Setting up a new project structure - Refactoring monolithic codebases - Implementing dependency injection - Organizing modules for team collaboration - Choosing between architectural patterns ## Prerequisites - Basic OOP programming knowledge ## Decision Tree ``` Architecture or code quality concern? +-- New project setup? -> Apply Clean Architecture layers (Api/Core/Infrastructure) +-- Class doing too much? -> Apply SRP - split by responsibility +-- Need to extend behavior? -> Apply OCP - use interfaces, not if/else chains +-- Deep inheritance tree? -> Favor composition over inheritance +-- Hard to test? -> Apply DIP - inject abstractions, not concretions +-- Code duplicated? -> Extract shared logic (DRY), but avoid premature abstraction …

How to install
mdr add jnpiyush/agentx/core-principles@sha256:9c06e6a6376ff59fThe line at the top of this page pins the label v2.0.0, 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.
