Supports Linux x64 with glibc 2.39+, macOS arm64 and Windows x64. No Ruby, Rust or Node setup step is needed to install rb. Ruby Butler manages missing Ruby installations on Linux/macOS and prepares dependencies when your commands need them.
Reuses verified rb binaries from the runner tool cache. Cross-run caching of Ruby and installed gems is not implemented. Normal rb settings, including RB_PACKAGE_BACKEND, apply.
