Marketing Skills

marketingskills is a collection of markdown-based "skills" that give AI coding agents specialized knowledge for marketing tasks. It's built for technical marketers and founders who already use AI coding agents like Claude Code, OpenAI Codex, Cursor, or Windsurf and want those agents to handle conversion optimization, copywriting, SEO, analytics, and growth engineering with actual frameworks instead of generic output.

Each skill is a markdown file the agent reads when it detects a relevant task. A central product-marketing skill acts as shared context: every other skill checks it first to understand the product, audience, and positioning before generating anything. Skills also cross-reference each other, so a request to improve conversion rate might pull in cro, copywriting, and ab-testing together.

Key features

• Wide skill coverage: nearly 50 skills spanning SEO (seo-audit, ai-seo, schema, programmatic-seo), CRO (cro, signup, onboarding, popups, paywalls), copy (copywriting, copy-editing, cold-email, emails, social, sms), paid/measurement (ads, ad-creative, ab-testing, analytics), growth/retention (referrals, free-tools, churn-prevention, community-marketing, lead-magnets), sales/GTM (revops, sales-enablement, launch, pricing, competitors), and strategy (marketing-ideas, marketing-psychology, customer-research).
• Shared product context: the product-marketing skill stores product, audience, and positioning info so other skills don't ask you to repeat it every time.
• Cross-referencing skills: skills point to related skills (e.g. copywriting ↔ cro ↔ ab-testing) so agents pull in adjacent frameworks automatically.
• Agent-agnostic format: built on the Agent Skills spec, so it works with Claude Code, Codex, Cursor, Windsurf, and any compliant agent, not locked to one vendor.
• Multiple install paths: CLI installer, Claude Code plugin marketplace, git clone, git submodule, fork, or a multi-agent tool (SkillKit).
• Selective installs: install all skills or just the ones you need (e.g. only cro and copywriting).
• Open contribution model: MIT licensed, PRs welcome for new or improved skills.

Ideal use cases

This fits teams and solo founders who already run an AI coding agent day-to-day and want it to produce marketing work (landing page copy, SEO audits, A/B test plans, email sequences, pricing pages) grounded in established frameworks instead of ad-hoc prompting. It's a good match for technical marketers, indie hackers, and agencies who want repeatable, documented workflows they can version-control alongside a codebase.

It's less useful if you don't use an agent that supports the Agent Skills spec, since the skills are markdown instructions an agent reads, not a standalone app or dashboard. It also won't replace actual execution tools: it gives an agent the knowledge to draft an ad, plan an experiment, or audit SEO, but you still need your own analytics, ad platforms, and CMS to act on the output. If you want a fully autonomous marketing agent rather than a skill library to drop into your own agent setup, the README points to a separate paid product (Magister) for that.

Installation

The recommended path uses the skills CLI:

# Install all skills
npx skills add coreyhaines31/marketingskills

# Install specific skills
npx skills add coreyhaines31/marketingskills --skill cro copywriting

# List available skills
npx skills add coreyhaines31/marketingskills --list

For Claude Code, install via the plugin marketplace:

/plugin marketplace add coreyhaines31/marketingskills
/plugin install marketing-skills

You can also clone the repo and copy skills manually:

git clone https://github.com/coreyhaines31/marketingskills.git
cp -r marketingskills/skills/* .agents/skills/

Or add it as a git submodule for easier updates:

git submodule add https://github.com/coreyhaines31/marketingskills.git .agents/marketingskills

A multi-agent option, SkillKit, installs skills across several agent tools at once:

npx skillkit install coreyhaines31/marketingskills

If running the install command from inside an agent session, pass the agent explicitly (e.g. -a claude-code) since non-interactive runs may default to the universal .agents/skills/ directory instead of .claude/skills/.
