SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill standardizes Ruby gem creation by applying Andrew Kane's battle-tested patterns, reducing boilerplate, and increasing maintainability.

Core Features & Use Cases

  • Guided gem scaffolding: Creates a minimal, production-ready gem skeleton with a clean lib/ entry point.
  • Pattern-driven APIs: Enforces explicit config, module structure, and Rails integration patterns without hard Rails coupling.
  • Refactoring & API design: Supports refactoring gems and designing stable, maintainable APIs across versions.

Quick Start

Create a new gem named my_gem following Kane's patterns and place the core API in lib/my_gem.rb.

FAQPage Schema
How do I create a production-ready Ruby gem with a clean module structure?▼

You create a production-ready Ruby gem by applying Andrew Kane's patterns, which enforce a minimal lib/ entry point, explicit module structure, and minimal dependencies to ensure long-term maintainability.

What is the best way to design a stable Ruby gem API without hard Rails coupling?▼

The best way to design a stable Ruby gem API is using explicit configuration and on_load Rails integration patterns, preventing hard Rails coupling while still supporting seamless framework integration when Rails is present.

How do I refactor an existing Ruby gem to follow maintainable design patterns?▼

To refactor an existing Ruby gem, this skill applies disciplined testing patterns, explicit configuration, and minimal dependency rules to align the codebase with stable, production-ready API design standards.

Does this Ruby gem scaffolding approach require Rails as a dependency?▼

This approach does not require Rails as a dependency; it uses on_load hooks for optional Rails integration, keeping the core gem decoupled and ensuring minimal dependencies.

Why does my Ruby gem need explicit configuration and on_load hooks for Rails integration?▼

Your Ruby gem needs explicit configuration and on_load hooks to avoid loading Rails components eagerly, ensuring the gem loads safely in non-Rails environments while integrating cleanly when Rails is detected.
