Installs 49 marketing skills Codex loads on demand
Marketing Skills is a free, open-source library of 49 marketing skills packaged in the portable, file-based skills format. Each skill is a SKILL.md folder with an expert playbook that an AI agent can load when your task matches it — so you can ask for landing page copy, an SEO audit, or an email sequence and get a proven approach instead of a blank prompt. Install the whole library into your project with one command: `npx skills add coreyhaines31/marketingskills`. It's MIT-licensed and works across tools that support the skills format.
Kickstart prompt
Paste this into Codex to get set up and oriented in one move:

How skills work with Codex
Codex is OpenAI's coding agent that works in your repo — reading files, running commands, and shipping changes. Marketing Skills gives that workflow a marketing brain: 49 skills, each a plain SKILL.md folder holding an expert playbook for one discipline — copywriting, SEO, paid ads, lifecycle email, pricing, CRO, and more.
Because the skills are portable, file-based instructions that live in your project, Codex can read and follow them the way it reads any other file in your repo. Point it at the relevant skill when you ask for marketing work and it works from that playbook, rather than improvising from a one-line prompt.
Install and use
Install the full library from your terminal, right inside your project:
- Run `npx skills add coreyhaines31/marketingskills` in your repo
- The skills install as a portable, file-based set of SKILL.md folders
- Ask Codex for a marketing task and point it at the matching skill
- The agent follows that skill's playbook — copy, SEO, ads, email, and more
- It's free and MIT-licensed — open, fork, or customize any skill
What you can do with it
The library spans the full marketing stack, so you can go from strategy to execution without leaving your workflow. Draft and rewrite landing page copy, run a technical and on-page SEO audit, write cold email and lifecycle sequences, generate ad creative and plan paid campaigns, pressure-test pricing and packaging, plan a launch, and set up analytics tracking.
Since the skills are plain files in your repo, they're transparent and easy to tune. Open any SKILL.md to see exactly what Codex is following, edit it to match your brand and voice, and commit the changes alongside your product code.
