Agent State in the Tmux Status Line
Summary
Explains a method to visualize per-pane agent state in tmux by scraping the process tree and the visible screen, rather than relying on window titles. It provides a background poller script that classifies each pane into action/working/idle and updates tmux pane options, which are then rendered in the window status. The piece also covers cross-agent differences (Claude Code, Codex, Grok) and the fragility of footer text as a detection signal.
