What
The SDK wire schema now includes an optional aborted: true field on assistant messages that were cut short by an interrupt or abort before the stream completed.
Details
- Present when
stop_reasonwas never received and content may end mid-word - Absent on normally completed messages
- Allows SDK hosts to visually distinguish truncated responses from complete ones
Evidence
Schema addition (search for "True when this assistant message was truncated by an interrupt/abort")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
