Product moves Aug 10, 2026

On August 7, Anthropic gave Claude Code the ability for sessions to message each other.

The official description: instead of re-explaining yourself in another session, you can tell Claude to do it — "It sends a summary (not your history or files), and the other session picks it up mid-task" (the post, August 7, 2026). Sending a summary means this is a lossy handoff; "picks it up mid-task" indicates an asynchronous, interruptible message model; and the handoff is triggered by a human instruction, not by an agent deciding on its own whether to notify a peer. The day before, a list of "why agents have not been widely adopted yet" circulating in enterprise circles had, as its fifth item, exactly this: "that handoff between agents is still mostly diy" (endorsed by Box CEO Aaron Levie, the post). Pain point named, vendor ships the next day; ⚠️ that connection is our editorial judgment, and neither side put it that way. ⚠️ And one cheap misreading to head off in passing: this is not the same thing as the secret message board in item 1 (that was agents operating outside their granted usage, parasitic on a store shared across multiple evaluation processes that all had write access), and this brief holds zero evidence about this feature's actual isolation boundary — which means it can be read neither as safe nor as unsafe.
