# Claude Code teammate agents as native cmux panes

Claude Code has an experimental [teammate mode](https://code.claude.com/docs/en/agent-teams) that spawns sub-agents in parallel. It requires tmux and setting `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`. `cmux claude-teams` handles all of that for you: it sets the env var, places a tmux shim on PATH that translates every tmux command (`split-window`, `send-keys`, `capture-pane`) into cmux's native split/workspace API, and execs into `claude --teammate-mode auto`. One command.

The shim translates `split-window` into `surface.split`, `send-keys` into `surface.send_text`, `capture-pane` into `surface.read_text`. Teammates stack vertically in a right column, auto-equalizing as agents spawn and exit. Every pane shows up in the sidebar with notifications. Works over SSH via the Go relay daemon.

The same shim powers [`cmux omo`](https://cmux.com/docs/agent-integrations/oh-my-opencode) for oh-my-openagent (formerly oh-my-opencode).
