lycheeverse/lychee-action

I've discovered a useful GitHub Actions plugin: lychee-action . It scans Markdown and HTML files in a repository, extracts all hyperlinks, checks their availability, and fails the build if any of them does not return an HTTP 200 status code. I've already integrated it into my blog repository . The result was instructive: after a few days of pair programming with Claude Code, I had to remove/replace more than 350 broken links. What surprised me most was not just the disappearance of some COVID-related YouTube videos, but also the removal of previously published articles by outlets such as Wired and Snob .
