Multiple terminal windows of Claude no longer need you as the “messenger” — v2.1.224 lets them chat privately among themselves.

First, understand how AIs “chat privately” with each other

If you frequently use Claude Code, you’ve probably run into this scenario: you open three terminal windows—one modifying the backend API, one writing the frontend calls, and one running tests. After Window A finishes updating the interface, you have to manually copy and paste the change details into Window B, telling it “the interface is ready, time to integrate.”

You are the messenger between the AIs.

On August 7, 2026, Anthropic released Claude Code v2.1.224, which introduced the cross-session messaging feature, and officially announced it the next day. In simple terms: Claudes in different terminal windows can now send messages to each other on their own.

You only need to tell the Claude in Window A something like “notify the backend window of the API changes,” and Claude will write a summary itself and send it to the Claude in Window B via an internal messaging channel. Window B receives it and reads the message during the gap between tool calls, without interrupting the task currently being executed.

💡 Analogy: It’s like colleagues sending private Slack messages—no need for you to relay them; they handle it themselves.
