Anthropic, a leading AI research company, has released an update to Claude Code, a coding assistant designed to enhance productivity and collaboration for developers. The latest version, 2.1.224, introduces a groundbreaking feature: cross-session messaging. This innovation allows separate coding sessions on macOS to communicate directly, streamlining the workflow and reducing the need for manual context switching.

The new feature is powered by two tools: ListAgents and SendMessage. ListAgents enables users to find and identify other active sessions running on their Mac, while SendMessage facilitates the delivery of messages between sessions. When a session receives a message, it is displayed as a labeled card with a link back to the sender.

According to Anthropic's documentation, messages between sessions are limited to text and warnings, excluding conversation history, files, and permissions. This ensures that sensitive information remains secure and local, without being transmitted to the company's servers.

The cross-session messaging feature sits alongside Claude Code's existing subagents and Agent Teams tools, providing users with a comprehensive set of collaboration and productivity tools. With this update, developers can now share knowledge and resources more efficiently, accelerating their work and driving innovation forward.
