Use when working in a Ruby project - provides authoritative sources for documentation, typing, and tooling

Use when writing or running tests in a Ruby project that uses minitest or test-unit. These frameworks have deceptively similar APIs with critical naming differences that cause NoMethodError at runtime. Consult this before writing assertions, running specific tests, or using setup/teardown lifecycle methods.

Use at session start for Ruby projects (Gemfile, .ruby-version, or .tool-versions present). Detect version manager BEFORE running ruby, bundle, gem, rake, rails, rspec, or any Ruby command.
