tmux! That was today's project. I'm using Claude Code Opus 4 to translate a K&R C computer algebra system (Macaulay) from the 1980's into C23. Finally getting to the "compiles but crashes" (64 bit issues) I found us living inside the lldb debugger. While I vastly prefer a true terminal to the periscope AI agent view in Cursor, it was still painful having at best a partial view of Claude's shell use, interleaved with our chat. What I wanted was a separate terminal session AI and I could share as equal partners.

tmux is the quickest way to implement such an idea.
