oh-my-openagent subagents as native coterm panes
coterm omo integrates oh-my-openagent (formerly oh-my-opencode), a plugin for OpenCode that orchestrates specialist agents across Claude, GPT, and Gemini in parallel. Each agent gets its own tmux pane. coterm omo uses the same tmux shim as coterm claude-teams: fake TMUX env var, every tmux command translated to coterm splits. It auto-installs the plugin into a shadow config so ~/.config/opencode stays untouched.
The shim also intercepts terminal-notifier calls and routes them through coterm notify. Works over SSH via the Go relay daemon.
