# Blog: Content Engine for Rankings & AI Citations

Full-lifecycle blog management: strategy, briefs, outlines, writing, analysis,
optimization, schema generation, repurposing, and editorial planning. Dual-optimized
for Google's May 2026 Core Update, March 2026 core quality baseline, March and
June 2026 spam enforcement, and AI citation platforms (ChatGPT, Perplexity,
Google AI Overviews, Gemini). Google treats gen-AI optimization as SEO, not a
separate discipline.

### Command Routing

1. Parse the user's command to determine the sub-skill

   - `rewrite` → `blog-rewrite` (optimize existing posts)
   - `analyze` → `blog-analyze` (quality scoring)
