Under the hood
No documentation found
Transcript building gained a withoutAttachmentHooks option to skip attachment hooks
What
When Claude Code rebuilds the transcript sent to the API, a new option called withoutAttachmentHooks lets the caller skip the normal attachment hooks and instead use a plain path when re-serializing a human turn's attachments.
Why
The finding does not say why a caller would want to bypass attachment hooks, only that the option now exists.
