ccrail
ccrail is a tmux sidebar for Claude Code. It gives every session a live context-window usage bar, the model name, and an activity indicator, all in one panel that stays put as you move between tmux windows, and you can switch sessions straight from it.

It's written in Python 3 and bash, using only standard-library curses, so there's nothing to install beyond tmux 3.0+ and Claude Code.
