Ruby 3.2+ with RBS & Steep

To add static typing to Ruby, use RBS to define type signatures in a `sig/` directory and Steep to check them. This approach enforces type safety and catches errors before runtime, improving overall code maintainability.

Yes, you can enforce both code style and type checking in Ruby 3.2+ by combining RuboCop for style consistency and Steep with RBS for type safety. This ensures strict coding conventions and robust type definitions across your project.

The best way to maintain large Ruby codebases is introducing static type checking with RBS and Steep alongside RSpec tests and RuboCop. This enforces strict type definitions and quality standards, leading to more robust applications.

Yes, this static typing approach works with Ruby on Rails applications. You can ensure critical business logic modules adhere to strict type definitions and coding standards by defining types in `sig/` before deployment.

To check type definitions and code style, run the Ruby skill in your current project directory. It validates RBS type signatures in `sig/` and enforces coding conventions using Steep, RSpec, and RuboCop.
