GitHub announced Copilot Vision general availability on July 1, 2026, allowing developers to attach screenshots to Copilot conversations as visual context.
Primary source: GitHub Changelog, “Copilot Vision is generally available”.
A screenshot can shorten “make this component look like that.” It can also become an invisible source of truth: unlabeled attachment controls, image-only requirements, generated markup with no semantics, and an error state communicated only by a thumbnail badge.
The accessibility target should be stronger than “a screen reader can upload a file.” A keyboard or screen-reader user must be able to understand the supplied requirements, remove or replace the image, follow processing state, and verify the generated interface.
Add a text contract beside the screenshot
