Helps you write and optimize meta descriptions for search engines with built-in awareness of SERP pixel width limits (about 920px desktop, 680px mobile) rather than just character counts. It knows to include CTAs, target keywords, and unique value propositions, and it handles CJK character width differences since they take up roughly double the space of Latin characters. Part of kostja94's marketing-skills collection alongside title tags, copywriting, and Google Search Console analysis. The pixel-based approach is smarter than the old 155-character rule you still see everywhere, and it ties into the broader SEO workflow if you're using the other on-page skills from the same pack.
