About Marketing Skills (Corey Haines)
What it is
Marketing Skills is an MIT-licensed collection of Agent Skills by Corey Haines aimed at technical marketers and founders who work inside coding agents. A shared product-marketing skill captures your positioning once, and every other skill reads it first, so copy, emails and ads stay consistent. Skills cover SEO and content, conversion optimisation, copywriting and copy editing, cold email and email sequences, social, video and image briefs, paid ads and ad creative, A/B testing, launches, pricing and competitor research.
Key features
- Product-marketing context skill that the other skills build on
- Copywriting, copy-editing, email, SMS and social skills
- SEO audit, AI-SEO, programmatic SEO, schema and site-architecture skills
- Ad and ad-creative skills plus A/B testing and analytics guidance
- Cross-referenced skills (for example customer research feeds copywriting and CRO)
- Installs through the skills CLI, a Claude Code plugin marketplace or git clone
How to install
Run npx skills add coreyhaines31/marketingskills (add --skill copywriting to pick individual skills or --list to see them). In Claude Code you can instead run /plugin marketplace add coreyhaines31/marketingskills and /plugin install marketing-skills. Because the skills follow the SKILL.md standard they also work in Codex, Cursor, Gemini CLI and other skills-capable agents.
Pricing and rights
Free and MIT-licensed. The README lists disclosed "Verified Partner" tool integrations that fund the project, and several links carry referral tags; the skills themselves do not require any paid tool.
Who it is for
Founders, growth marketers and solo creators who draft landing pages, emails, ads and SEO content with Claude Code or another coding agent.
Verdict
The most complete marketing skill pack we found, with sensible structure and an active maintainer. It is written for conversion and SEO work, so long-form editorial or video production needs other tools, and partner mentions are worth noting.
Pros
- Broad coverage of marketing tasks
- Shared positioning context keeps outputs consistent
- MIT licence and several install paths
- Actively maintained
Cons
- Aimed at SaaS/startup marketing more than editorial content
- Sponsored partner integrations inside the README
- Loading many skills adds context overhead
