What testing frameworks are supported?

The skill provides templates and best practices for Minitest and WebMock, though the architectural principles apply to RSpec and other testing suites as well.

Does it manage versioning and releases?

It provides a standardized release workflow, including Semantic Versioning (SemVer) guidelines, CHANGELOG maintenance, and Rake tasks for automated publishing.

Does this skill help with Rails engines or integrations?

Yes, it provides specific patterns for Rails integration using Railties and ActiveSupport hooks to ensure your gem loads lazily and doesn't bloat host applications.

Can I use this for API client development?

Yes, it includes a dedicated API client pattern that covers resource-based organization, authentication handling, and HTTP-specific error hierarchies.

How does it handle gem configuration?

It implements a standard block-based configuration pattern that includes environment variable fallbacks and a reset method for clean test state management.

Developer Tools

Standardizes the creation and architecture of production-grade Ruby gems using best practices for structure, testing, and distribution.

About

The Gem Builder skill provides comprehensive architectural guidance and implementation patterns for developing high-quality Ruby gems. Whether creating standalone libraries, CLI tools, API clients, or Rails integrations, this skill ensures adherence to industry standards like Semantic Versioning, YARD documentation, and minimal dependency management. It streamlines the development process by providing ready-to-use templates for configuration blocks, error hierarchies, and testing suites, helping developers avoid common anti-patterns like heavy DSLs or premature Rails requirements.

Key Features

Lazy-loading Rails integration using Railties and ActiveSupport hooks
Robust custom error hierarchy and input validation patterns
Integrated testing setup with Minitest and WebMock templates
9 GitHub stars
Standardized gem directory structure and gemspec optimization
Best-practice configuration patterns with block-based DSLs

Use Cases

Bootstrapping a new standalone Ruby library or CLI tool from scratch
Refactoring an existing codebase into a modular, distributable gem
Building a lightweight Rails integration that maintains performance through lazy loading
