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.

Claude Code v2.1.242

Clicks outside every display are refused instead of dispatched

You'll notice
Useful2 Signal2
Computer Use

Clicks landing outside every display are refused with a prompt to take a fresh screenshot.

What

Before a click or cursor move is hit-tested, its point is checked against the list of displays. A point that lands on no display is refused, with an instruction to take a fresh screenshot or move the mouse first, rather than being sent to the OS.

Details
  • Refusals use the reason code hit_test_off_display.
  • If listing displays fails or reports zero displays, the check is skipped and the previous behaviour applies, logging "[computer-use] off-display backstop skipped".
Evidence

hit_test_off_display

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