What
Messages from teammates now carry more identity information:
- The sender display label now uses the message's own
senderNameinstead of a fixed display name, and shows an 'unverified' qualifier when the message is flagged asisUnverified. - When several consecutive messages from the same display name are grouped ('coalesced') into one entry, that grouped entry now also records the
senderNameandisUnverifiedstatus, not just a message count.
Why
This lets Claude Code show who actually sent a teammate message and flag when its sender couldn't be verified, even when messages are grouped together in the chat.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Confirmed since
Anthropic's documentation has since written up unverified, on Agent SDK reference - TypeScript.
