Corey Haines has released a collection of AI agent skills designed to help technical marketers and founders use coding agents for conversion optimization, copywriting, SEO, analytics, and growth engineering. The skills work with Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent supporting the Agent Skills spec. The project is open source and contributions are welcome.
How the skills are structured
The skills are markdown files that give AI agents specialized knowledge and workflows for specific marketing tasks. When added to a project, the agent can recognize marketing tasks and apply relevant frameworks and best practices. The product-marketing skill is the foundation — every other skill reads it first to understand the product, audience, and positioning before proceeding.
Skills are organized into seven categories: SEO & Content, CRO, Content & Copy, Paid & Measurement, Growth & Retention, Sales & GTM, and Strategy. Each category contains multiple individual skills, such as seo-audit, cro, copywriting, ads, referrals, revops, and customer-research. Skills cross-reference each other; for example, copywriting links to cro and ab-testing, while customer-research feeds into copywriting, cro, and competitors.
Installation methods
Users can install skills via the npx skills CLI, Claude Code's plugin system, or by cloning the GitHub repository. The CLI detects which agents are installed and asks where to place the skills — for Claude Code it installs into .claude/skills/, and universal agents use .agents/skills/. A tip notes that running the command from inside an agent session may install only to the universal directory, which Claude Code does not read, so users should pass the agent explicitly with the -a flag.
For Claude Code, users can add the marketplace and install all marketing skills with `/plugin marketplace add coreyhaines31/marketingskills` and `/plugin install marketing-skills`. Alternatively, cloning the repo and copying the skills folder, or adding it as a submodule, are also supported. The SkillKit tool can install skills across multiple agents simultaneously.
v2.0 migration notes
Version 2.0 renames 17 skills and consolidates page-cro and form-cro into a single cro skill. Users upgrading from v1.x will have stale old-name folders alongside the new ones and should remove them manually. The context file has moved from .claude/ to .agents/ and was renamed from product-marketing-context.md to product-marketing.md. The new version includes fallbacks so nothing breaks if users don't migrate immediately.
Usage examples
Once installed, users can ask their agent to help with marketing tasks directly. For example, "Help me optimize this landing page for conversions" invokes the cro skill; "Write homepage copy for my SaaS" uses the copywriting skill; "Set up GA4 tracking for signups" uses the analytics skill; and "Create a 5-email welcome sequence" uses the emails skill. Users can also invoke skills with slash commands like /cro, /emails, or /seo-audit.
The project is maintained by Corey Haines, who also runs Conversion Factory, an agency for conversion optimization and growth strategy, and offers AI marketing training. A companion guide called Coding for Marketers is available for those new to terminal and coding agents.
