What
When a message to another agent cannot be delivered, the transcript now shows a one-line reason instead of the full instruction block sent to the model, which keeps the long text out of your view.
Details
- Covers no reachable recipient, ambiguous or degraded name resolution, and a name that now resolves to a different agent than earlier in the conversation.
- A new warning fires when a local session claims an identity previously confirmed as remote, ending "which was confirmed earlier as a session elsewhere" and "that is suspicious if you did not set it up."
Evidence
now means a different agent than it did earlier in this conversation; asked Claude to confirm which one it wants.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
