strategy-registry

What problem does it solve?

This Skill provides robust patterns for implementing the Strategy pattern with registry-based dispatch, enabling extensible systems where new handlers or strategies can be added without modifying core logic. It solves the problem of hard-to-maintain if/elif chains and promotes the Open/Closed Principle.

Core Features & Use Cases

• Extensible Dispatch: Easily add new handlers for file types, event types, or commands.
• Multiple Registry Patterns: Demonstrates dict-based, decorator-based, and auto-discovery (__init_subclass__) registration.
• Protocol Definition: Enforces a clear interface for strategies using typing.Protocol.
• Use Case: Building a plugin system for a code editor where new language support can be added by simply dropping in new handler modules.

Quick Start

Use the strategy-registry skill to implement a file handler that dispatches based on file extension.
