GEO Content Engineering (Agent Skill)

An open Agent Skill (SKILL.md format) for creating and rebuilding web content so generative engines (ChatGPT, Gemini, Perplexity, Google AI Overviews) extract, cite, and mention it. This is the discipline called GEO (Generative Engine Optimization), also known as AI visibility, LLM SEO, or answer engine optimization.

What it does

The skill turns a general agent into a GEO content specialist. It walks the agent through the retrieval mechanic (chunk, embed, retrieve, ground, cite) and applies it as a repeatable workflow: gate crawler access, structure text into extractable blocks, force citations with concrete data, cover query fan-out, keep content fresh, add verifiable authorship, apply correct semantic markup and JSON-LD, strip machine-tell language, publish with an input register, and measure Share of Mentions against a competitor benchmark.

It covers two modes: creating new content, and rebuilding existing pages (baseline first).

Install

Place the folder in your agent's skills directory (for example ~/.claude/skills/ for Claude Code, or upload in claude.ai settings). The agent loads the full instructions only when a task matches the description.
