Comprehensive link checking and validation for documentation. Validate internal links, external URLs, anchors, detect redirects, monitor link rot, and generate sitemap validation reports.
How do I install it?

Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
