What probably matters to youSection of the release
A screenshot scale factor is documented alongside region, but both shipped capability profiles turn adaptive resolution off so it is unreachable.
What
The computer-use screenshot tool takes a region of four integers naming a rectangle to zoom into, measured against the full-screen screenshot taken before the batch. A scale factor is also documented, with an explanation of its effect on token cost, but both capability profiles shipped here turn adaptive resolution off, so scale is not exposed.
Details
region is described as (x0, y0, x1, y1) and applies to zoom only
the repeated sentence about the frontmost application having to be in the session allowlist is now drawn from one shared string across the key, type and hold descriptions
Evidence
(x0, y0, x1, y1): Rectangle to zoom into. For zoom only.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
