Claude Code v2.1.251

Teammate agents report a structured result when a turn ends

Under the hood
Useful2 Signal3
Teammates

Teammate agents send back a structured result when a turn ends, not just an idle notice.

What

When a teammate agent running inside the same process finishes a turn, including after a transient failure, it now sends back a structured result payload rather than only an idle or summary notice, so the coordinating side knows what actually happened.

Details
  • The payload carries the turn result and whether the sender is still reachable.
  • Delivered through the same mailbox notification used before; applies to all in-process teammates with no flag.
Evidence

turn-end result delivery failed

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
