New rendering code has appeared in the prompt input area of Claude Code. It builds a combined signal from an agent state, a tmux hint (tmux is a terminal multiplexer that lets you split a terminal into panes), and the existing standalone banner, and if any of these is present it would switch to a different layout: a title bar plus a dedicated agent-mode row, instead of the normal banner-and-border layout.
