·2026.09.02 10:36

Key point

AWS Labs has open-sourced CAO, a multi-agent orchestrator that enables parallel or sequential control of various AI coding CLIs, including Claude Code and Codex.

Details

AWS Labs has released the CLI Agent Orchestrator (CAO). CAO runs multiple AI coding CLIs in isolated terminal sessions based on a local server, allowing a supervisor to delegate tasks to workers in parallel or sequentially.

Key Features and Supported Environments

CAO maintains each agent as an independent CLI process, leveraging native authentication and features as-is. The supported providers are as follows:

  • Supported CLIs: Kiro CLI, Claude Code, Codex CLI, Antigravity CLI, Hermes, Kimi CLI, MiniMax Code, GitHub Copilot CLI, OpenCode CLI, Oh My Pi (OMP) CLI, Cursor CLI, Grok Build CLI
  • Required Environment: Python 3.10+, tmux 3.3+, uv

Operation and Scalability

Users run cao-server and then start a supervisor using the cao launch command from the project directory. Agent status can be monitored and controlled via the Web UI or tmux. It also offers complex orchestration capabilities, including Kubernetes (Amazon EKS) deployment, workflow pipelines, cross-session memory, and self-learning loops.
