50 Claude and Codex Skills for Marketers: What They Do and Who Built Them

Writing landing pages, planning emails, reviewing SEO, and preparing reports all involve repeatable steps. When you use AI for these jobs, you often end up explaining those steps again.

Skills let you save a process and reuse it. Some help with one task, such as editing a draft. Others cover several connected tasks, such as researching customers, writing copy, and reviewing a landing page.

This guide covers 50 skills from 10 creators. You’ll find what they do, examples of where they fit into marketing work, and links to the skills and the people behind them.

What is a skill?

A skill is a folder of instructions that an AI tool can use for a particular task. It can also contain examples, templates, reference material, and scripts.

For example, an email skill might explain how to plan a welcome sequence, choose the timing, write each message, and review the calls to action.

Anthropic’s skills documentation and OpenAI’s skills documentation explain how these instruction folders work. For a marketing introduction, read our guide to Claude Skills and what they mean for marketers.

A skill still needs useful input. If your customer research is missing, the skill cannot supply real customer evidence. If it needs campaign data, you must provide that data or connect a supported service.

How to read this list

Some projects contain dozens of skills. Others contain one.

The 50 entries below include individual skills from larger collections. Where several skills share a creator, they also share the collection’s popularity figure.

Most collections support both Claude Code and Codex. Some are built specifically for Claude Code. Support for Claude’s website or desktop interface varies, so check the installation instructions for the version you use.

The creators and their marketing skills

Corey Haines: a broad collection for everyday marketing work

Corey Haines’ Marketing Skills covers copywriting, SEO, email, advertising, conversion optimization, and more. The repository has approximately 55.9k GitHub stars and documents support for Claude Code and Codex.

Its shared product context is particularly useful. You can record your audience, positioning, product details, and tone once, then use that information across different tasks.

For example, you could use Customer Research to review interview notes, Copywriting to draft a landing page, and CRO to review the page’s structure.

Give it your product information, customer evidence, and the action you want visitors to take. Review the resulting copy against those inputs. For more help with the page itself, see our approach to landing page writing for B2B SaaS.

Charlie Hills: a shared writing voice across social formats

Charlie Hills’ Social Media Skills includes tools for writing voice, hooks, Reels scripts, carousels, and YouTube thumbnail prompts.

The repository has approximately 4.3k stars and includes instructions for Claude Code and Codex.

Voice Builder is a useful place to begin. It uses an interview and writing samples to create guidance that other skills can read.

For example, a founder could provide three to five posts they wrote themselves, explain their audience, and use the resulting guidance when developing posts or scripts.

The visual skills help prepare briefs and prompts. Our guide to AI image prompts for B2B marketers provides examples of how to describe the style and purpose of a marketing visual.

The collection is useful when work needs several steps and review points. Its influencer skills, for example, separate finding creators, assessing their fit, and preparing a campaign brief.

You could supply a campaign goal, audience, budget, and shortlist of creators. The skills provide a process for comparing candidates and documenting expectations. You still need to verify audience data and agree on the final partnership terms.

Daniel Agrici, who publishes as AgriciDaniel, created Claude SEO. Its specialist skills cover technical SEO, local SEO, content, structured data, and AI search.

The repository has approximately 19.6k stars. The skills featured here are built for Claude Code.

A content marketer could use the technical review to identify crawling or indexing concerns, then share the findings with a developer. A local business could review location pages, business details, and review signals.

Treat the output as a set of findings to investigate. Some recommendations require access to website settings, analytics, or other data. Our SEO content writing service explains how search research connects with content planning and production.

Zubair Trabzada: audits and client deliverables

Zubair Trabzada’s AI Marketing Suite includes website audits, proposals, copy, email sequences, and reports.

The repository has approximately 2.8k stars and is built for Claude Code.

Its appeal for agencies and consultants is the output format. It provides workflows for turning a review into a marketing report or service proposal.

For example, you could review a client’s website, check the findings yourself, and use the proposal skill to organize a suggested scope of work. Any audit scores should be treated as the tool’s assessment. They don’t establish how the client’s campaigns are performing.

Matt Van Horn: recent conversations and content research

Matt Van Horn’s Last30Days researches recent conversations across several online sources.

It has approximately 65k stars and supports Claude Code and Codex. It is a general research skill with useful marketing applications.

You could research a category, competitor, or customer problem before planning content. The result can help you find discussions, questions, and language to investigate further.

Source coverage depends on your setup. Some sources work without extra configuration; others require access or credentials. Check the original discussions before turning findings into claims in an article.

Siqi Chen: editing formulaic AI writing

Siqi Chen’s Humanizer reviews writing for patterns such as stock phrases, inflated claims, repetitive structures, and unnecessary filler.

The repository has approximately 59.4k stars and supports Claude Code and Codex.

It is useful as an editing pass after you have a draft. You can also provide your own writing samples to guide the style.

Check the rewrite for meaning and accuracy. Smoother writing still needs examples, evidence, and a clear point. Our guide to improving generic AI-written marketing content looks at those wider editorial decisions.

Three ways to use these skills together

Improve a landing page

Start with customer interviews, sales notes, or support questions. Use Customer Research to identify common problems, objections, and phrases.

Add those findings to your product context. Then use Copywriting to prepare the page and CRO to review the message, structure, and form.

Before publishing, check every product claim and decide how you will measure the change. Use A/B Testing if you have enough traffic and a suitable experiment.

Turn an article into a week of social content

Begin with an approved article that contains useful examples or evidence. Use LinkedIn Repurposer to develop posts around separate points.

Use the Content Planner to organize the week. If a point needs a visual explanation, prepare a carousel brief. Read each draft to check that it adds something useful.

The quality of the source article matters. Our blog writing service for B2B SaaS explains how we approach the research and structure behind those articles.

Review a page for AI search

Use AI SEO or Daniel Agrici’s GEO skill to review a page. Check whether its main claims are clear, supported, and accessible.

Make changes that improve the page for readers, then track what happens. Citation counts, referral visits, and relevant enquiries answer different questions. Our guide to AI visibility scores explains how to think about those measurements.

How to choose your first skill

Pick one task you repeat often. Gather the inputs you normally use, run the skill, and compare the result with your current process.

Keep a short record:

• What input did you provide?
• What did the skill produce?
• How much editing or checking did it need?
• Did it help you finish the task?

Before installing, read the project’s requirements. Check the supported tool, any required software, and whether optional data or publishing services cost extra. An open-source skill can still rely on paid tools.

Start with a draft, a copy of a page, or an exported report. Once you understand the output and the review it needs, you can decide where it belongs in your regular work.
