Marketing Agent Skills for Claude Code

AI agent skills for marketing tasks, built for Claude Code and similar AI coding assistants (Cursor, Windsurf, Codex, Cline, Roo Code).

Hey 👋🏾 I’m James, the founder of Marketing In Action.

I built a set of marketing agent skills for Claude based on how I actually do product marketing, GTM strategy, and growth work.

See demo:

Each skill is designed to help Claude reason like a marketer. It analyzes context, clarifies positioning, breaks down decisions, and produces outputs you can actually use, from strategy to execution.

I am currently experimenting with vibe coding, and this is one of the projects I’m building with that knowledge.

This repo is the Claude skills version of the MIA Resources I have developed:

• Product Marketing Templates & Resources Library: 50+ Product & Growth Marketing templates, frameworks, and resources to execute marketing with clarity.

• AI Prompt Frameworks & Templates for Marketers: 50+ frameworks and templates that marketers and founders use to produce consistent, high-quality outputs from AI tools like ChatGPT Projects, Claude Projects, Gemini Gems, Custom GPTs & OpenAI Assistants.

The problem that agent skills solve is that every new ChatGPT/Claude project or custom GPT currently forces you to start from scratch. You have to manually recreate prompts, reupload knowledge files, and re-explain context each time. When you switch from one AI tool to another, none of that logic carries over, so you end up doing fresh customization just to get back to a usable baseline.

Agent skills move that logic out of individual prompts and into reusable reasoning patterns. Instead of rebuilding context per project or per tool, you define how the AI should think once and apply it across workflows, projects, and assistants. That makes AI setups more portable, more consistent, and far easier to maintain as your work becomes more technical.

These skills make it easier to unify and apply the knowledge and prompts from the knowledge files and custom GPTs/prompts. Get the skills on GitHub here.

🔍 How to use this

The skills are grouped into two main areas:

1—Strategy & GTM Thinking Skills

Use these when you need clarity before execution.

Examples include: product positioning, product messaging, product launch and GTM, marketing ideas, product ideas, landing pages and SaaS pages, ICP and customer segmentation, case studies, experimentation, performance marketing, and lifecycle marketing campaigns.

2—Execution & Optimization Skills

Use these to turn decisions into action.

This includes: outbound GTM with Clay, workflow automation with n8n and OpenClaw, AI humanization, and vibe-coding marketing agents.

For every skill, Claude can:

• Analyze your situation and assumptions

• Ask the right clarifying questions

• Generate structured outputs you can directly apply

• Adapt recommendations based on your stage, market, and constraints

🧭 Why this exists

I created this for marketers like me who are getting their hands dirty with the technical side. People exploring GTM engineering, vibecoding workflows, and using AI to actually build, not just brainstorm.

If you have feedback or think there’s a skill that should be included, drop me a note on Twitter/X or LinkedIn.
