Unclear It is not clear whether the separate main-reply handling is ever active, so the visible effect is unknown.
What
While a reply streams in, Claude Code can briefly hold back the output before showing it. It used to track this with a single flag shared by all replies. It now tracks the main reply separately and reports holds on it as a separate kind of event.
It also releases a held reply early when the first piece of a content block arrives before any complete block has come in.
Why
This could change how and when streamed output appears on your screen.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
