SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you design Ruby gems that are simple, reliable, and production-ready instead of overly clever or fragile. It reduces the risk of bloated dependencies, unsafe Rails loading, and inconsistent library structure.

Core Features & Use Cases

  • Gem Architecture: Organizes entry points, modules, version files, and optional Railties or engines in a clean, consistent way.
  • Rails Integration: Uses lazy loading patterns and on-load hooks so gems integrate safely with Rails applications.
  • Testing and Packaging: Encourages Minitest, minimal runtime dependencies, and practical gemspec conventions for maintainable releases.
  • Use Case: A developer building a new Rails library can use this Skill to define the public API, structure the codebase, and choose patterns that scale across multiple versions and database adapters.

Quick Start

Ask for a Ruby gem implementation that follows Andrew Kane's patterns, including a clean entry point, safe Rails integration, and Minitest tests.

FAQPage Schema
How do I structure a production-ready Ruby gem with minimal dependencies?

A production-ready Ruby gem requires explicit entry point organization, version files, and low-dependency packaging. This structure prevents bloated dependencies and ensures maintainable releases across multiple gem versions.

What is the best way to integrate a Ruby gem with Rails safely?

The best way to integrate a Ruby gem with Rails is using lazy loading patterns and on-load hooks. This prevents unsafe Rails loading issues and ensures the gem integrates safely without interfering with the application startup process.

Why does my Ruby gem break when Rails loads, and how do I fix it?

Ruby gems break during Rails loading when they lack lazy loading patterns. Fix this by applying on-load hooks and safe Rails integration techniques that defer initialization until the Rails application environment is fully loaded.

Can I use Minitest for testing a Ruby gem instead of RSpec?

Yes, you can use Minitest for testing a Ruby gem. Minitest is encouraged for its simplicity and reliability in packaging production-ready gems, providing practical testing conventions that align with minimal library architecture principles.

How do I design an adapter pattern for a Ruby gem supporting multiple database adapters?

Designing an adapter pattern for a Ruby gem involves creating a clean class macro DSL and structuring the public API to scale across multiple versions and database adapters. This pattern maintains a minimal library architecture while supporting diverse backend integrations.

Do I need a Railtie or Engine for my Ruby gem to work with Rails?

You do not always need a Railtie or Engine for your Ruby gem to work with Rails. Optional Railties or engines can be included for deeper integration, but simple gems can rely on lazy loading and on-load hooks for safe Rails compatibility.
