A free library of about 50 marketing skills for your AI agent

Marketer Corey Haines's Marketing Skills is a free, open-source (MIT) collection of skills for Claude Code, Codex, Cursor and other agents that follow the Agent Skills standard. It covers conversion copy, SEO audits, AI search optimisation, schema, cold email, ad creative, pricing, churn and more, and every skill first reads one shared file describing your product and audience. A popular post called it version 1.2.0 with 29 skills, but the project page now shows version 2.0 with around 50, so it has grown fast. It also lists paid partner tools, which it clearly labels.

Why it mattersIt's a quick way to give an agent a marketer's checklists instead of writing your own from scratch. Fill in the product file first, then try one skill such as the SEO audit on a single page. As with any skill, skim what it does before you install it, because skills can tell your agent to run commands.

How we knowCompany figures are labelled as their own claims; anything we couldn't verify is labelled as a report or a claim.
