This one routes any URL through markdown.new to get a clean Markdown version of the page, which is surprisingly handy when you're asking Claude to read docs, blog posts, GitHub issues, or changelogs. Instead of parsing messy HTML, Claude fetches the Markdown-rendered version and can copy, quote, or summarize it directly. The skill is smart enough to skip the proxy for login pages, paywalls, and interactive dashboards where it would break things, and it falls back to the original URL if it hits a 403 or CAPTCHA. It's a small quality-of-life win that makes content extraction feel less like a scraping job.
