Several accessibility policy pre-built Custom Checks have been added to the Custom Checks library. For example, there is a check that looks for non-descriptive link text. (WCAG 2.0, Level A, 2.4.4 Link Purpose)

Many times, links will get created where the link text is the URL for the link. A screen reader user would hear “h-t-t-p-colon-slash-slash-webaim-dot-org-slash-projects-slash-screenreadersurvey9” instead of “Check the WebAIM Screen Reader Survey 9.” Having descriptive link text is especially helpful when a screen reader is configured to scan web pages for links only. This custom check looks for “http” and / or “www” as part of the link text on a web page.

Another accessibility custom check compares the ALT text of an image to the image filename to ensure they are not the same.
