Claude Code v2.1.211 15 Jul 2026

Screenshot Save-to-Disk for Claude in Chrome

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: true on a computer or browser_batch tool 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_disk has 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

New save_to_disk handling function with text "Screenshot saved to: " (search for "Screenshot saved to:")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
