This action supports accessible content sharing on GitHub by leaving an automated reminder whenever an image is shared on a GitHub Issue, Pull request, or Discussion without meaningful alternative text (alt text). Alternative text helps convey the context of the image to those who use assistive technologies such as a screen reader and removes accessibility barriers.

For guidance on setting alternative text, see Alternative text for images on Primer.

Images on GitHub default to using the filename as alt text. This action flags when the alt text has not been updated from the default:

Note: Ordinarily, setting alt="" will mark images as decorative. However, GitHub currently renders all images as a link. To avoid rendering links with no names, we recommend always setting alt text on images in GitHub.

Copy this workflow into any repo you want the accessibility-alt-text-bot to run in.
