What it does, concretely

Handling varied marketing tasks inside an AI agent requires providing it with the right methodological frameworks each time. Marketing Skills solves this by offering a library of 50 specialised markdown files that give the agent the knowledge and workflows suited to each marketing situation.

In practice, each skill is a markdown file the agent reads before acting. The product-marketing skill serves as the foundation: all other skills consult it first to understand your product, audience, and positioning. Skills cross-reference each other, for example seo-audit works with schema and ai-seo, or copywriting with cro and ab-testing.

The library is aimed at technical marketers and founders who use AI agents such as Claude Code, Cursor, Windsurf, or OpenAI Codex to automate growth tasks: copywriting, SEO audits, conversion optimisation, email campaigns, paid advertising, public relations, and more.

However, if you do not use an AI agent in a terminal or a compatible editor, these skills will be of no use: they do not work as standalone applications or web interfaces.

What it offers

  • ·50 skills covering copywriting, SEO, CRO, paid advertising, emails, growth, strategy, and customer research.
  • ·The product-marketing skill centralises product context and is automatically read by all other skills before each task.
  • ·Skills cross-reference each other according to documented dependencies, for example customer-research feeds into copywriting, cro, and competitors.
  • ·À-la-carte installation via the npx skills add command to include only the skills relevant to your project.
  • ·Compatibility with multiple AI agents: Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent supporting the Agent Skills specification.
  • ·Two partner integrations available: Converly for server-side conversion tracking, and Ploy for site optimisation and SEO.
  • ·Open-source library under the MIT licence, with community contributions accepted via pull request.
