coreyhaines31/marketingskills: A marketing skills library for AI agents

This project is a collection of AI agent skills for marketing tasks, provided as Markdown files and covering conversion rate optimization, copywriting, SEO, analytics, and growth engineering. Skills reference each other, with product-marketing as the foundational skill that others read before running to understand the product, audience, and positioning. Supported agents include Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent following the Agent Skills spec. Available skills span dozens of areas including ab-testing, ad-creative, ads, ai-seo, analytics, aso, attribution, churn-prevention, cold-email, copywriting, cro, and seo-audit. Installation is recommended via CLI: run npx skills add coreyhaines31/marketingskills to install all skills, use --skill to install only specific ones, and --list to view available options. The CLI detects installed agents and asks where to install; Claude Code goes into .claude/skills/, while generic agents share .agents/skills/. The library is free under the MIT license, with tool integrations from several verified partners. For technical marketers and founders who want AI coding agents to take on marketing work, these skills remove the need to write prompts yourself; marketers new to the terminal and coding agents can refer to the companion guide Coding for Marketers.
