Brief

cmux 0.63.x adds a Claude Code Agent Teams mode that wraps the experimental teams feature in a more usable terminal UI. @nummanali highlights it as a major quality-of-life improvement over tmux because agents appear as native cmux panes that can be resized and rearranged freely, while Lawrence Chen notes the command also handles env vars, tmux compatibility, and SSH support automatically.

Introducing cmux Claude Code Agent Teams:

cmux claude-teams --dangerously-skip-permissions

Teammates/subagents spawn as native cmux pane splits. They stack vertically in a right column and auto-equalize as agents spawn and exit.

cmux claude-teams automatically sets CLAUDECODEEXPERIMENTALAGENTTEAMS=1 and shims tmux on PATH with cmux's tmux-compat layer, so you don't need to update your Claude config. All arguments forward to Claude Code, and it works over cmux SSH too.

Out in the latest version of cmux (0.63.x).
