I tried to vibe code on Windows. It broke me. So I built my own terminal.

Every AI coding setup I saw online looked the same: Mac, tmux, agents running in split panes, everything humming along perfectly. I was on Windows. It did not hum. The tmux wall tmux is the backbone of serious AI agent workflows. Persistent sessions, split panes, detach and reattach while your agents keep running. On Windows, native tmux doesn't exist. Fine — I'll use WSL. WSL: close enough to break everything WSL feels like Linux. For about 20 minutes, you think you've solved the problem. Then the path issues start. Windows sees: C:\Users\wooyoung\projects\wmux WSL sees: /mnt/c/Users/wooyoung/projects/wmux Same folder. Completely different contexts. AI agents write files into WSL.

The worst part: it works — until it doesn't. You're 40 minutes into a session before realizing your agent has been operating in the wrong di
