RBS-Inline Type Generator

About

The RBS-Inline Type Generator skill empowers developers to implement type safety in Ruby projects without the overhead of maintaining separate .rbs files. By embedding type signatures directly into source code as structured comments, it streamlines the development workflow and ensures that documentation and implementation stay in sync. The skill intelligently infers types to minimize 'untyped' declarations, supports complex Ruby features like Data and Struct, and provides built-in validation steps using the rbs-inline transpiler and Steep type checker.

Key Features

• Performs deep code analysis to infer types and eliminate 'untyped' declarations
• Embeds type signatures directly in Ruby files using # @rbs syntax
• Integrates with Steep for advanced static type checking and error reporting
• Supports specialized Ruby 3.x constructs including Data and Struct classes
• Automates the generation and validation of RBS files from inline comments
• 1 GitHub stars

Use Cases

• Migrating legacy Ruby codebases to a typed system without creating a complex file directory
• Adding type safety to Ruby gems and libraries while keeping logic and types in a single file
• Improving IDE autocompletion and developer experience in Ruby-based API development
