Anthropic's official account @ClaudeDevs announced a new Claude Code feature on X on August 7, 2026. The original post reads as follows.
New in Claude Code: your sessions can now message each other. Instead of having to re-explain yourself in another session, you can now tell Claude to do it. It sends a summary (not your history or files), and the other session picks it up mid-task.
What the Announcement Means
According to the announcement, separate Claude Code sessions — independent working sessions — can now send messages to one another. Previously, continuing work in another session required the user to re-explain the context from scratch. Now, users can simply tell Claude to pass that information along directly between sessions. What gets sent is a summary, not the full conversation history or files, and the receiving session picks up the in-progress work mid-task.
What It Means for Users
For users who run multiple Claude Code sessions at once, this is likely to reduce the friction of re-explaining context every time work moves from one session to another. It could be particularly useful for workflows involving parallel tasks or sessions split across different areas of work.
What's Not Specified
The official announcement does not specify how the summary is generated or the exact procedure or limitations for sending messages between sessions. For the latest details, check Anthropic's official channels.
