How can I customize these reviews?

Check out the Hyperlint AI Reviewer docs for more information on how to customize the review.

If you just want to ignore it on this PR, you can add the hyperlint-ignore label to the PR. Future changes won't trigger a Hyperlint review.

Note specifically for link checks, we only check the first 30 links in a file and we cache the results for several hours (for instance, if you just added a page, you might experience this). Our recommendation is to add hyperlint-ignore to the PR to ignore the link check for this PR.

Is it worth including a screenshot of the feature configured?

[Encore-Encore]

As powerful as the feature is, its just a selector addition so not much to show off UI wise unfourtunley

[cdisher]

Doesn't that make it easier to choose a screenshot then? It makes it crystal clear where the feature exists instead of customers needing to "figure it out" since we have a lot of selectors. Great way to easily help with the distribution and product association problem.

Here's a great example from a recent announcement that is basically just a selector: https://developers.cloudflare.com/changelog/2025-04-09-workers-timing/
