What problem does it solve?

The Open/Closed Principle (OCP) advocates designing software so that existing code remains stable while new features are added through extension rather than modification.

Core Features & Use Cases

• Encourages designing abstractions and extension points to accommodate new requirements without touching existing code.
• Applies to library APIs, plugins, and modular architectures to reduce regression risk and simplify testing.
• Use Case: When adding a new feature, implement a new concrete class or strategy that conforms to an existing interface instead of altering existing implementations.

Quick Start

Introduce an abstract interface for a feature, create concrete extension classes, and wire them through a factory or dependency injection to enable new behavior without changing existing code.
