Takes a keyword or content brief through search-intent analysis, an H2/H3 outline, and a full draft with E-E-A-T signals (first-hand experience, named sources), plus a meta title/description pair — no keyword stuffing, ever. Use when the user asks to "write a blog post", "SEO article", "rank for [keyword]", "draft from this content brief", or "outline a post". Don't use for landing/sales page copy — that's landing-page-copywriter.
