Corey Haines

Corey Haines runs marketing-skills.com, a collection of 50 open-source marketing skills for AI coding assistants like Claude Code, Codex, and Cursor. It targets technically minded marketers and founders who want to use AI tools for marketing tasks without building every use case from scratch.

The skills cover areas including SEO, copywriting, conversion rate optimization, ads, lifecycle marketing, growth strategy, and research. The skills listed on this platform include an SEO audit for systematically checking a website's search optimization, programmatic SEO for automated, large-scale creation of SEO-optimized content instead of manually built individual pages, and content strategy for planning and structuring marketing content across different channels.

By bundling these as installable, ready-to-use skills, Haines significantly lowers the barrier to advanced marketing automation — instead of evaluating or building every tool individually, a fitting skill can be wired directly into existing AI workflows.
