This skill provides a comprehensive quality assurance framework for Ruby on Rails development by integrating three powerful tools: Solargraph for LSP diagnostics, Sorbet for static type checking, and Rubocop for style enforcement. It establishes a 'Guardian Cycle' and automated quality gates that trigger after each implementation phase, catching type mismatches, syntax errors, and style violations before they reach production. Designed for enterprise-grade repositories, it supports a gradual adoption path—moving from basic linting to strict type safety—enabling developers to maintain high-performance, maintainable, and A+ rated Ruby codebases.
