[DOCS] Claude in Chrome docs describe `save_to_disk` approval only, not disk write and returned path

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/chrome

Section/Topic

"Browser tools in plan mode" (read-only vs state-changing calls) and screenshot tooling.

Current Documentation

The Chrome integration page states:

As of v2.1.199, an otherwise read-only call that sets a state-changing input flag, such as … save_to_disk on a screenshot, also prompts for approval.

The page classifies taking a screenshot as read-only but does not document what save_to_disk does when set on a screenshot action.

What's Wrong or Missing?

Claude Code v2.1.211 implemented save_to_disk on screenshot actions so the image is written to disk and the tool returns the saved file path. Previously the flag had no effect. Automation authors and MCP integrators need the output shape and filesystem behavior, not only the permission implication.

Suggested Improvement

Add a short subsection under browser tools or screenshots:

On screenshot actions, save_to_disk: true writes the captured image to disk and returns the saved file path in the tool result. The call prompts for approval like other state-changing browser flags. Requires Claude Code v2.1.211 or later.

Include a minimal example of the returned path field if the tools reference documents screenshot parameters.

Impact

Medium - Makes feature difficult to understand
