This handles Open Graph meta tags so your links look good when shared on Facebook, LinkedIn, Slack, and similar platforms. It covers the four essential tags (title, description, image, url), walks through image specs (1200×630px is the sweet spot), and includes Next.js and raw HTML examples. The skill correctly distinguishes between Open Graph and Twitter Cards, which is helpful since many developers conflate them. One thing to note: pages with proper OG tags supposedly get 2-3x more clicks than bare URLs, though that claim feels optimistic. The testing links to Facebook's Sharing Debugger and LinkedIn's Post Inspector are genuinely useful for debugging why your preview looks broken.
