The artifact tool's upload_asset can now describe uploading a list of multiple local files at once
What
The description Claude sees for upload_asset, part of the Artifact tool, now distinguishes between uploading a single local file and uploading a list of several local files, phrased as "a list of N local files." This follows earlier work that expanded which file types (adding stylesheets and scripts) could be uploaded as assets.
Why
This suggests upload_asset can now handle multiple files in one call rather than requiring a separate call per file, which would make attaching several assets to an artifact more efficient.

The writer flagged doubt
The finding shows the description change implying multi-file support, but doesn't confirm the underlying upload mechanism itself changed.
