A dormant new banner layout for agent/tmux hints was added to the prompt input row but isn't active yet
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.
This code path is not yet reachable in this build, so nothing changes in what you see today.
This looks like groundwork for a future visual treatment when Claude Code is running as an agent or inside tmux, but since the path is currently dead, there is nothing to expect from it yet.
The finding shows the new render branch exists but does not establish that it can currently be triggered or what it will look like in…
