Marketing Skills is a free GitHub repo by Corey Haines. It gives Claude 50 marketing skills, covering copywriting, SEO audits, cold email, AI search, conversion, pricing, launches and a lot more. It's MIT-licensed, so you can use and change it however you want, and it works with Claude Code, Codex, Cursor and other agents that read skill files.
The reason it beats a folder of prompts is one file. Every skill reads .agents/product-marketing.md before it does anything: your product, your buyers, your positioning, your voice. You write that once. After that, the copy starts from your business instead of a blank page, and you stop explaining yourself at the top of every chat. Below is how to install it, how to write that file, and the prompts to start with.

The rest is one email away. Then every guide is open.
Put your email in once and you can read this guide and every other one on the shelf, including the ones from reels I haven't posted yet. I'll send you the link too, so you can find it again.
