What
The computer tool inside Claude in Chrome now supports a save_to_disk parameter that persists screenshots to a local temporary directory and returns the file path(s) in the tool result.
Details
- Pass
save_to_disk: trueon acomputerorbrowser_batchtool call to save screenshots to disk. - Claude includes the saved path(s) in its response so they can be attached for the user.
- If the screenshot directory cannot be created, the image is still returned inline.
- If
save_to_diskhas no effect in the current session context, Claude is instructed not to retry. - Supports PNG, JPEG, WebP, and GIF output formats.
- Screenshots are saved as
screenshot-<timestamp>-<n>.<ext>under a session-scoped temp directory.
Evidence
