What

When one agent sends a message to another, Claude Code wraps that message before Claude sees it. An agent here means a separate Claude working alongside the main one, such as a teammate. Messages marked as a whole message can now be wrapped in a different way. Before, every such message was wrapped the same way.

Why

This changes how messages from other agents are presented to Claude.
