Does this skill use RSpec for testing?

No, this skill strictly follows Andrew Kane's preference for Minitest to keep gems lightweight and avoid the overhead of heavy testing frameworks.

Is this skill suitable for enterprise Ruby projects?

Yes, the focus on simplicity, explicit code, and minimal dependencies makes these patterns ideal for high-scale, production-critical enterprise environments.

How does it handle Rails integration?

It utilizes ActiveSupport.on_load hooks and ensures the gem does not require Rails directly, maintaining a clean separation between the library and the framework.

Can I use this to refactor existing Ruby gems?

Absolutely. The skill can analyze existing gems to identify anti-patterns like heavy metaprogramming or unnecessary dependencies and refactor them into a cleaner structure.

Why avoid metaprogramming in gems?

The Kane philosophy prioritizes 'simplicity over cleverness' to ensure that code is easy to debug, performant in production, and accessible to other maintainers.

API Development

Builds production-ready Ruby gems using Andrew Kane's proven patterns for simplicity, minimal dependencies, and clean API design.

About

This skill equips Claude with the specific engineering philosophy and implementation patterns of Andrew Kane, the creator of widely used gems like Searchkick and PgHero. It focuses on creating high-performance, maintainable Ruby libraries that favor explicit code over metaprogramming, ensure Rails integration without tight coupling, and prioritize minimal runtime dependencies. It is ideal for developers building new gems or refactoring existing ones into battle-tested, production-grade structures using Minitest and standard library components.

Key Features

Implements Andrew Kane's signature 'class macro' DSL patterns
Enforces minimal runtime dependencies for lightweight and stable libraries
Generates Minitest-based testing suites for fast and reliable verification
Configures Rails integration using ActiveSupport.on_load to prevent coupling
Standardizes gem structures with explicit module organization and error handling
0 GitHub stars

Use Cases

Refactoring complex Ruby libraries to reduce metaprogramming and dependencies
Designing clean, intuitive APIs for internal or open-source Ruby projects
Creating a new Ruby gem from scratch with a production-ready foundation
