Show HN: Visual state tracking for AI agents in tmux (github.com)

I run multiple Claude Code and Codex sessions in tmux panes. The main annoyance was not knowing when an agent finished or hit a permission prompt without switching to each pane to check.

This plugin hooks into agent lifecycle events and changes pane borders, window titles, and status bar icons to reflect three states: running, needs-input, done. Colors reset when you focus the pane.

Works with Claude Code and Codex out of the box. Any other agent can integrate by calling a single shell script.
