This cookbook demonstrates two async multi-agent orchestration patterns using Claude: a fixed N-agent team with peer messaging through a shared hub, and dynamically spawned async subagents. Built on the Anthropic Python SDK and asyncio, it provides bare messaging and lifecycle mechanics without domain-specific tasks, allowing developers to see exactly which tools fire and in what order before adding their own tools and logic. The patterns run on any API key in under thirty seconds and include a message hub, messaging tools (send_message and wait_for_message), and a base agent loop that handles tool dispatching and inbox management.
