How to use marketingskills with Claude Code and AI agents

Updated · written with AI from the project's own documentation and checked against our catalogue data

marketingskills is an open-source collection of markdown files, called skills, that hold marketing frameworks and workflows for AI coding agents. Once the files are in your project, an agent such as Claude Code or Cursor can recognize a marketing task and apply the matching guidance. This guide shows you how to get the repository, how the skills fit together, and how to put them to work on landing pages, copy, SEO and tests.

Quick start

  1. 1Check prerequisites. Confirm you have an AI agent that supports the Agent Skills spec, such as Claude Code or Cursor.
  2. 2Clone the repository. Run the git clone command from the README to download marketingskills.
  3. 3Open the skills folder. Browse the skills folder to see each skill and its markdown files.
  4. 4Add the skills to your project. Place the skills where your agent can read them, following the repository's instructions.
  5. 5Start with product-marketing. Describe your product, audience and positioning so the foundation skill has context.
  6. 6Ask a specific marketing task. Request help with a task such as a landing page, copy edit or SEO audit in plain language.
  7. 7Review the output. Check the agent's suggestions against your own knowledge, since the README presents frameworks, not guaranteed results.

What you need before you start

marketingskills is built for AI agents, not for a standalone app. The source describes it as working with Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent that supports the Agent Skills spec.

If you are new to the terminal and coding agents, the README points to a companion guide, Coding for Marketers, that covers the basics.

  • An AI agent that supports the Agent Skills spec, such as Claude Code or Cursor
  • Git, so you can clone the repository
  • A project folder where you want the agent to work

Install marketingskills by cloning the repository

The install method is clone-and-build. Run the clone command from the README to download the repository to your machine. The source does not describe further install steps, so follow the repository's own instructions after cloning.

To find the skills, open the skills folder in the repository. Each skill has its own folder, such as skills/ab-testing/.

git clone https://github.com/coreyhaines31/marketingskills

Understand the skills and how they connect

Skills are markdown files that give an agent specialized knowledge and workflows for a specific task. When you add them to your project, the agent can recognize a marketing task and apply the relevant frameworks and best practices.

The product-marketing skill is the foundation. The README says every other skill checks it first to understand your product, audience, and positioning. The skills are grouped into areas including SEO and Content, CRO, Content and Copy, Paid and Measurement, Growth and Retention, Sales and GTM, and Strategy.

  • SEO and Content: seo-audit, ai-seo, schema, content-strategy
  • CRO: cro, signup-flow-cro, onboarding-cro, popup-cro, paywall-upgrade-cro
  • Content and Copy: copywriting, copy-editing, cold-email, email-sequence
  • Paid and Measurement: ads, ad-creative, ab-testing, analytics
  • Strategy: marketing-ideas, marketing-psychology, customer-research

Ask your agent for marketing help

Once the skills are in your project, describe your task to the agent in plain language. The agent decides which skill applies. The README notes that skills cross-reference each other, for example copywriting, cro and ab-testing are linked.

Give the agent context about your product, audience and goals. Because every skill reads product-marketing first, a clear product description helps the output.

  • Ask for a landing page review focused on conversion optimization
  • Ask for headline options for a specific audience
  • Ask for an SEO audit of a page or site structure
  • Ask for a plan for A/B testing a signup flow

Connect marketing accounts (optional)

The README links a guided tool connection workflow in tools/SETUP.md for scoped credentials and a first read-only result. Use this only if you want your agent to read your marketing accounts.

The README also lists Verified Partners, which are paid integrations. It states the library itself is free and MIT-licensed, and that partners never influence what the core skills recommend.

Contribute or get help

The README welcomes pull requests for improving a skill or adding one. It also asks people with problems or questions to open an issue on the GitHub repository.

  • Open a pull request to improve a skill
  • Open an issue on the GitHub repository for problems or questions

What people use it for

  • Reviewing a landing page for conversion issues using the cro skill
  • Drafting or editing marketing copy with the copywriting and copy-editing skills
  • Running an SEO audit with seo-audit and planning schema with schema
  • Planning an A/B test with the ab-testing skill
  • Writing cold outbound emails with the cold-email skill

Our verdict

marketingskills suits technical marketers and founders who already use AI coding agents and want shared marketing frameworks inside them. It is a poor fit for anyone who does not use AI agents, because the files are designed to be read by agents rather than used through a standalone interface.
