Marketing Skills
An open-source collection of 45 marketing skills for Claude Code and AI agents
Marketing Skills is an open-source collection of 45 marketing "skills" -- structured markdown workflows that teach an AI coding agent like Claude Code, Codex, or Cursor how to handle marketing tasks with real frameworks. Built by marketer Corey Haines and MIT-licensed (35,742 GitHub stars as of July 2026), it covers CRO, copywriting, SEO, ads, analytics, and more, invoked with commands like /cro or /emails. It's a powerful DIY layer -- but it hands your agent the know-how, not the hours: you still drive every task, review every draft, and decide what ships.
What Marketing Skills is
Marketing Skills (github.com/coreyhaines31/marketingskills) is a library of agent "skills" -- markdown files that give an AI coding agent specialized marketing knowledge and step-by-step workflows. When you ask your agent to "optimize this landing page," the matching skill kicks in with the right framework instead of a generic answer. It's built by Corey Haines (of Swipe Files and Conversion Factory), is MIT-licensed, and installs into Claude Code, Codex, Cursor, and other agents.
- 45 skills across 8 categories -- conversion, content & copy, SEO & discovery, paid & distribution, measurement, retention, growth, and strategy.
- Named, invokable workflows -- e.g. /cro, /emails, /seo-audit, /programmatic-seo, /ads, /launch, /pricing.
- Works with your agent -- install via `npx skills add coreyhaines31/marketingskills`, a Claude Code plugin, cloning, or a Git submodule.
- Open-source + MIT -- fork it, edit the skills, and keep whatever you build on top.
Where Marketing Skills fits in a founder's growth stack
Marketing Skills is the know-how layer for founders who already run an AI coding agent and want it to be competent at marketing, not just code. Instead of prompting from scratch, your agent draws on battle-tested frameworks for CRO, SEO, and copy. For a technical founder comfortable in Claude Code or Cursor, that's a real upgrade over a blank prompt -- see how do I use AI for marketing as a solo founder.
The catch is that skills are knowledge, not execution capacity. The agent still needs you to open it, describe the task, feed it your context, connect any data, and review each output -- every time. The frameworks are excellent; the operating and the judgment are still fully on you.
What Marketing Skills doesn't do -- and how Ceres complements it
A skills library makes a single agent smarter about marketing; it doesn't coordinate a whole marketing function, run on a schedule, connect to your analytics and channels, or keep an audit trail of what went out. Those are operating problems, not knowledge problems.
| Marketing Skills gives you… | …what running it still requires |
|---|---|
| A framework for a CRO or SEO task | You driving the agent through each task, every time |
| Copywriting and email skills | cold-email and content actually drafted, scheduled, and sent |
| An /seo-audit workflow | SEO content published and re-checked as it compounds |
| Knowledge inside one agent | A coordinated team, connectors, and an approval trail across channels |
That's the difference between a DIY toolkit and a managed service. Ceres -- the AI Growth Officer is a managed AI marketing team: an AI Growth Officer coordinates specialists that draft the SEO, copy, and outreach continuously, wired to your data, with every outbound action approval-gated so you review and approve before anything ships. Marketing Skills upgrades the agent you drive by hand; Ceres runs the function so you don't have to drive each task. If AI marketing is new to you, start with generative engine optimization.
