What

Claude Code adds a new function that marks a batch of "non-structured" mailbox messages as read for a given agent or team, logging either success or a warning if the mark-as-read fails (in which case the messages will be re-attached next turn).

Why

No code was found in the app that actually calls this function with its full set of arguments, so it isn't yet in active use.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
