💡 Quick Start Guide:
1. Initialize a new isolated session:
$ bash .agents/skills/multi-agent-mux-create/scripts/create_session.sh \\
--workspace "$TARGET_DIR" --agent claude --role developer --isolate \\
--herdr-server multi-agent-mux
2. Attach to the running session:
$ HERDR_SERVER_NAME=multi-agent-mux herdr agent attach <session_name>
3. Gracefully stop the session:
$ bash .agents/skills/multi-agent-mux-stop/scripts/stop_session.sh \\
--session <session_name> --agent claude
