Claude Code Teams

cmux claude-teams launches Claude Code with agent teams enabled. When Claude spawns teammate agents, they appear as native cmux splits instead of tmux panes, with full sidebar metadata and notifications.

Usage

cmux claude-teams
cmux claude-teams --continue
cmux claude-teams --model sonnet

All arguments after claude-teams are forwarded to Claude Code. The command defaults teammate mode to auto and sets the environment so Claude uses cmux splits.

How it works

cmux claude-teams creates a tmux shim script and configures the environment so Claude Code thinks it's running inside tmux. When Claude issues tmux commands to manage teammate panes, the shim translates them into cmux socket API calls.

Creates a tmux shim at ~/.cmuxterm/claude-teams-bin/tmux that redirects to cmux __tmux-compat
Sets TMUX and TMUX_PANE environment variables to simulate a tmux session
Prepends the shim directory to PATH so Claude finds the shim before real tmux
Enables CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 and sets teammate mode to auto

Environment variables

Variable	Purpose
`TMUX`	Fake tmux socket path encoding the current cmux workspace and pane
`TMUX_PANE`	Fake tmux pane identifier mapped to the current cmux pane
`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS`	Enables Claude Code agent teams feature
`CMUX_SOCKET_PATH`	Path to the cmux control socket for the shim to connect to

Directories

Path	Purpose
`~/.cmuxterm/claude-teams-bin/`	Contains the tmux shim script that translates tmux commands to cmux API calls
`~/.cmuxterm/tmux-compat-store.json`	Persistent storage for tmux-compat buffers and hooks

Supported tmux commands

The shim translates these tmux commands into cmux operations:

new-session, new-window → creates a new cmux workspace
split-window → splits the current cmux pane
send-keys → sends text to a cmux surface
capture-pane → reads terminal text from a cmux surface
select-pane, select-window → focuses a cmux pane or workspace
kill-pane, kill-window → closes a cmux surface or workspace
list-panes, list-windows → lists cmux panes or workspaces
