dev-gtm-claude-skills is a collection of open-source Claude Code skills for SEO, GEO (Generative Engine Optimization), AI discoverability, and developer marketing. Each skill is a self-contained package — a SKILL.md that tells Claude when and how to use it, optional Python tooling, and a README with full usage docs. Install once, then run from Claude Code, Claude Desktop, or Claude.ai with a plain-language prompt.

These skills are built for developer-focused companies — DevTools, AI-agent platforms, observability, and B2B SaaS — that need their documentation and content to be cited by AI systems like ChatGPT, Claude, Perplexity, and Gemini, not just indexed by Google.

What is GEO? Generative Engine Optimization is the practice of optimizing content so it gets surfaced and cited by AI answer engines. Traditional SEO tools optimize for search crawlers; these skills audit the signals — structured content, llms.txt, internal linking, and documentation completeness — that LLMs use when deciding what to recommend.

What you can do in one prompt

• Audit developer docs for SEO and AI discoverability — 33 checks, scored 0–100
• Score API & SDK documentation quality, endpoint by endpoint
• Check AI-readiness — robots.txt, llms.txt, and llms-full.txt in one pass
• Generate 3-month SEO performance reports vs competitors
• Fix internal linking — find orphan pages and dead-ends, get paste-ready suggestions
• Produce SEO content briefs as formatted .docx outlines

What Are Claude Code Skills & Agent Plugins?

Claude Code skills (also called agent skills or coding-agent plugins) are modular instruction packages that give AI coding agents domain expertise they don't have out of the box. Each skill in this repo includes:

• SKILL.md — structured instructions, workflows, and decision frameworks that tell the agent when and how to act
• Python tools — optional stdlib-only CLI scripts for the skills that crawl, score, or render reports
• Reference docs — templates, scoring guides, and checklists the skill loads on demand

Because every skill follows the open SKILL.md standard, it isn't locked to a single product. The same package runs in Claude Code, Claude Desktop, Claude.ai, and any other agent that reads the standard (see Multi-Tool Support).
