What

SendUserFile is the tool Claude uses to send you a file. Its attachments are now checked once, and the result of that check is passed on to the upload instead of being worked out again. The message tool does the same. Attachment data can also carry upload_suspected_limit_bytes, a size limit Claude Code suspects the upload ran into.

Separately, when Claude Code starts a child session (another Claude Code process it launches), it now passes autoPickedByLevel along with the permission mode and proactivity level.

Why

When a file upload fails, Claude Code can report more detail, including a likely size limit.
