Mise Runtime & Environment Expert

This skill provides authoritative guidance on using mise (formerly rtx) for managing programming language runtimes, CLI tools, and project-specific environments. It enforces a mise-first philosophy, prioritizing modern toolchains like uv and bun while maintaining global and project-level configurations through a single, unified interface. It is specifically designed to help developers replace fragmented tools like nvm, pyenv, and rbenv with a faster, more efficient multi-tool manager that optimizes shell performance and ensures reproducible environments.
