Agent-native multiplexer

Emerging tool category: a terminal multiplexer that treats running AI agents as first-class objects alongside panes: agent status panels, done/waiting notifications with sounds, direct agent attach, and orchestration APIs. herdr is the archive's exemplar, validated from two angles: dhh needs it to stay in flow across 16 parallel agent threads ("constantly making decisions... unblocking an agent or ready for a new task"), while omer-hamerman finds the agent features secondary to it simply being a better multiplexer (beautiful-defaults). Both data points suggest the category wins by being excellent at the old job first.

Third data point: typecraft adds agent state as a navigation primitive (fuzzy-find agents by blocked/working/idle/done) and the inversion — agents driving the multiplexer via agent-skill-files (report).

Counterpoint: sam-natale gets rough parity without a new multiplexer. workmux adds an agent sidebar, a dashboard and worktree-per-task automation to tmux. That suggests the category may end up as a layer over existing multiplexers as much as a replacement (augment-over-replace).
