Wait - Block Until Messages Arrive

Wait for messages on specific topics, enabling synchronization between agents and coordinated handoff workflows.

When to Use

• Waiting for another agent to complete work
• Coordinating handoff between agents
• Blocking until a response or acknowledgment arrives
• Synchronizing at specific points in distributed workflows

How It Works

The hive msg sub --wait command polls the specified topic every 500ms until:

• A message arrives (success, exit 0)
• The timeout is reached (prints JSON status, exit 1)

Default timeout is 24h for --wait mode. Messages are NOT acknowledged unless --ack is used.
