Overview
SEO On-Page: Meta Description Skill is an open-source Agent Skill from the kostja94/marketing-skills collection (MIT). It teaches AI coding agents focused marketing / SEO workflows so they can produce production-ready guidance instead of generic advice.
Guides optimization of the meta description tag for search engines and SERP display.
Google truncates by pixel width (920px desktop, ~680px mobile), not character count. Character limits are approximate—CJK chars are wider (2× Latin), so fewer fit in the same pixels.
Official skill id: meta-description. Source path: skills/seo/on-page/description.
