The Best Claude Code Skills for Marketers (2026)

Most marketers think of Claude Code as a developer tool. It isn't: it's an AI agent that can read a URL, call APIs, and run a task end to end from a plain-English sentence. Add a few agent skills and the same terminal your engineers live in becomes a marketing workstation.

A skill is just a document that teaches the agent how to do one job well. Here are the categories worth wiring in, and the one that turns Claude Code into a video maker.

Why run marketing from an agent at all

You describe the outcome; the agent does the steps. No new dashboard to learn, no tab-switching, no babysitting a queue. When the tool lives where you already work, you actually use it daily, which, for short-form, is the whole game.

Skills worth adding

• Research skills: pull a competitor's angles, summarize a niche, or cluster keywords, without leaving your prompt.
• Copy skills: draft hooks, captions, and ad variations against a brief instead of a blank page.
• SEO / content skills: outline and draft posts to a house style, so your blog keeps shipping.
• Video: Riffkit, the one that produces an actual asset. Say "riff this TikTok into a video for my product" and the skill runs the whole pipeline: it studies a winning video's formula and recreates it with your product and character, post-ready, in 9 languages.

For the first three categories, the largest open collection is Corey Haines' marketingskills repo, 47 MIT-licensed skills covering CRO, copywriting, SEO, ads, and analytics. Setting it up has one trap that costs most people an hour, so here's a working install and usage guide.

How Riffkit fits

Riffkit is a hosted skill: the spec is open source, rendering runs on Riffkit's servers, and it's listed on ClawdHub. It's the difference between an agent that talks about marketing and one that ships a video you can post. If you already tell Claude Code what to build, telling it what to film is the natural next step.
