Unclear What the new formatting looks like or why it was needed compared to the previous formatting is not stated.
What
When formatting the result of a SendMessage tool call that includes an "inline handback" (content handed back inline in the conversation), Claude Code now checks a new condition. When it's true, the content is formatted using a new transform that takes into account harness note count, harness tail count, and a harness section hash, instead of the previous formatting method.
Why
This changes how inline handback content from SendMessage is presented, though the finding doesn't specify what visible difference this makes for users.
