What
File downloads have a new failure reason, could_not_name. It covers a download that arrived in full but that Claude Code could not save under its intended name.
Separately, MCP tool information (MCP is the protocol for connecting external tools) can now carry an anthropic/reportsUploads key.
Why
Download error messages are more specific, so it is clearer the data arrived and only the naming step failed.
