Rust with Clap solved this forever ago.

Also - don't write CLI programs in languages that don't compile to native binaries. I don't want to have to drag around your runtime just to execute a command line tool.

Apparently that ship has sailed. Claude Code and Gemini CLI requires Node.js installation, and Gemini README reads as if npm is a tool that everybody knows and has already installed.

Opencode is a great model agnostic alternative which does not require a separate runtime

Opencode uses TS and Golang, it definitely needs a runtime for the TS part. CPU usage hovers around 100% for me on an MBP M3 Max.

I meant that it’s bundled with the binary such that you don’t need to make sure some random version of eg Node is available
