Claude now previews whether it would be allowed to auto-reply to a new artifact comment while it's still busy

What

When a new comment or summon arrives on an artifact (a generated document or piece of content) while Claude is still busy handling something else, Claude Code now runs a quick permission-only check to forecast whether its eventual automatic reply would actually be allowed. It then posts an early status, either 'working' or a decline, instead of waiting until the busy work finishes to find out the reply was going to be blocked.

Why

This gives earlier, more accurate feedback about pending artifact replies instead of leaving the requester waiting only to learn later that permission would have been denied.
