Under the hood
Comment-thread handoff responses now pass through a handOff field
What
When Claude Code explains why it didn't automatically reply to or edit a comment thread (for example, because the artifact is generated from a source file), the response now includes a handOff field carried through from the input, in addition to the existing summary and detail text.
Why
This makes the handoff information available alongside the explanation, though the finding doesn't specify what consumes this added field.
