# Claude Code adds cross-session messaging

Anthropic's Claude Code now lets sessions message each other, sending summaries instead of history or files.

- Users can instruct Claude to send a summary to another session, which picks it up mid-task.
- Messaging works both ways: users can ask another session a question and get the answer back.
- Claude can autonomously message another session when a change affects its work.
- Available on macOS and Linux after updating Claude Code.

## Why it matters

Developers using Claude Code can now coordinate work across sessions without re-explaining context, improving multi-task workflows.
