core-principles skillA

core-principles is agent-read markdown (skill) from jnpiyush/agentx: 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..

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.

What the file says

# 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
