Unclear The finding does not say how a message's provenance comes to be judged 'forged' in practice.
What
In Claude Code's swarm mode, where multiple Claude instances (teammates) work together and exchange messages, the transcript format now tracks whether a message's origin can be trusted. A teammate message can be tagged verified="false" when its provenance is judged 'forged' (meaning it looks like it came from a teammate but its origin is suspect).
When a message is marked this way:
its content is no longer scanned for mentions or tool names
the sender's name is shown with an (unverified) label next to it
Why
This makes it easier to spot a message that was injected or spoofed to look like it came from a legitimate teammate, rather than having it silently treated the same as a genuine message.
