What
The tool for messaging another agent no longer auto-allows in every permission mode; in some modes it defers to classifier review.
Details
- The permission check can now return a passthrough behavior with a message stating that classifier review is required.
- Recipient names must match a single-line pattern.
- Over-long summaries are truncated rather than rejected outright.
- The classifier input string now carries the summary, shutdown reason, request id and plan feedback.
Evidence
Message to another agent requires classifier review.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
