Anthropic has introduced a new feature for its Claude Code sessions, allowing them to message each other with updates and other information. This feature is available on macOS and Linux for users running the latest version of Claude Code. According to 9to5Mac, the feature enables users to share findings, ask questions, and coordinate work across multiple sessions.

The cross-session messaging feature allows Claude to deliver messages between sessions, which can be useful when working on different parts of the same project. For example, if a change in one session breaks what another session is building on, Claude can warn the affected session. The feature also enables handing over findings, coordinating parallel worktrees, getting status from long-running work, and replying across machines.

Users do not need to compose messages themselves, as Claude will write the actual message based on the prompt. This feature is designed to improve collaboration and workflow efficiency for users working with multiple Claude Code sessions.
