01
What Marketing Skills is
Marketing Skills is an MIT-licensed open-source collection of Markdown-based Agent Skills created by Corey Haines. Its current README documents support for Claude Code, OpenAI Codex, Cursor, Windsurf and hosts that implement the Agent Skills specification.
- Skills cover SEO, AI SEO, CRO, copywriting, analytics, paid ads, social, launch, pricing, retention and RevOps.
- The product-marketing skill provides shared context used by downstream workflows.
- The library is instructions and workflow structure, not a standalone AI model or SaaS dashboard.
02
What changed in v2
The current v2 migration section documents 17 renamed skills, consolidation of page-cro and form-cro into cro, and a move toward a cross-agent .agents/product-marketing.md context file.
- Old v1 folders can remain beside new names after reinstalling.
- The current README should be treated as the live rename map.
- The shared .agents layout makes context less tied to one agent host.
03
How to install and use it
The recommended cross-agent route is npx skills add coreyhaines31/marketingskills. The project also documents selected-skill installs, a Claude Code plugin path, clone/submodule workflows and SkillKit.
- Install only the workflows you need if a full library is unnecessary.
- Populate accurate product-marketing context before expecting good downstream work.
- Verify the agent actually discovers the installed skill rather than answering generically.
04
What a skill library does not guarantee
A skill can make a process more repeatable without making every output correct. The underlying model can still hallucinate facts, misread analytics or suggest outdated platform tactics.
- Keep publishing, ad-budget and production changes behind appropriate review.
- Treat GitHub popularity as an attention signal, not proof of marketing performance.
- Model usage, APIs and connected tools can still carry costs even though the library itself is open source.
