DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Screenshots can zoom into a rectangle; the image scale option is off in this build

Not switched on
Useful3 Signal4
Computer Use Notable

Screenshots can zoom into a rectangle, but the documented image scale option is not exposed in this build.

A screenshot scale factor is documented alongside region, but both shipped capability profiles turn adaptive resolution off so it is unreachable.

region
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.
