• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

https://www.w3.org/WAI/WCAG21/Understanding/link-purpose-in-context.html: links whose text just says something vague like "read more" aren't accessible. Folks navigating through a page's links need more context than that. More info: https://www.w3.org/WAI/WCAG21/Understanding/link-purpose-in-context.html

- To do XYZ, [click here]

I'd like to add an OctoGuide rule to lint for this. But I recognize this is actually a pretty annoying rule for folks who aren't already bought into accessibility and understand it. That'll probably be true even if the rule report has nice explanations.

So, I think this is blocked on #70.

Additional Info

I'd been meaning to file issues for more granular accessibility points than just text-image-alt-text for a bit, but hadn't gotten around to it. Thanks @helen for reminding me of this issue in particular!
