Quick answer: install three things first. Corey Haines’ free marketingskills for day-to-day copy, CRO and strategy; Anthropic’s official Marketing plugin for campaign plans and brand review; and claude-seo if search matters to you. Everything else on this list of 12 is an add-on. Install commands, GitHub stars and a chained campaign workflow are below. Never used a terminal? Start with Claude Code skills for non-developers. Running client work? See skills for marketing agencies.
Most marketers who open Claude Code hit the same wall. The model is capable, but every session starts from zero. You explain your brand voice again, paste your ICP again, and remind it again which buzzwords are banned.
Skills fix that. A skill is a folder with a SKILL.md file that tells Claude how to do one job, and Claude loads it on its own when the task matches. Install the right ones and Claude Code stops acting like a smart intern and starts acting like a team member who has read the playbook.
The catch: there are now tens of thousands of public skills, and most were written by developers for developers. This guide filters the list down to the skills that do marketing work. For each one you get the source, whether it is free or paid, what it does, the exact install command, and GitHub stars and last commit date as checked on 1 November 2026. At the end there is a workflow that chains them from research to a published, measured campaign.
New to the concept? Start with what Claude Code skills are, then come back.
The short answer: which Claude Code skills should marketers install first?
If you install only three things, install Corey Haines’ marketingskills for execution, Anthropic’s official Marketing plugin for campaign planning and brand review, and claude-seo if search is a channel you own. All three are free and open source. Together they cover copy, CRO, email, SEO audits, competitor briefs and reporting.
Everything else on this list either goes deeper on one channel (blog content, programmatic SEO) or adds convenience you can pay for.

Star counts move daily. Treat them as a popularity signal, not a quality score.
How we picked these skills (and what we left out)
A skill made this list if it does real marketing work, has a public source you can read before installing, and was updated within the last few months. We checked every repo against the GitHub API on 1 November 2026 and read each README for install steps.
Why these criteria? Three reasons.
- Readable source. A skill is instructions plus, sometimes, scripts that run on your machine. If you cannot read it first, you are trusting a stranger with your terminal. Open repos let you check.
- Recent commits. Claude Code changes fast. Plugin commands and frontmatter fields shift between releases. A skill untouched for a year may still load, but it often references old behaviour.
- Marketing, not coding. Many “top skills” lists are padded with test runners and linters. Useful, but not for a content lead.
What we left out
- Packs that only sell through a checkout page with no preview of the files.
- Skills that duplicate a better-maintained one above (there are dozens of “SEO writer” clones).
- Raw prompt libraries with no
SKILL.mdstructure, since Claude Code will not auto-load them.
Takeaway: stars tell you a repo is popular. The README and the SKILL.md tell you whether it fits your work. Read both.
The 8 best free Claude Code skills for marketers
The free options are not the budget tier. For marketing, the open-source packs are the most complete and most maintained skills available. Here is what each does and how to install it.
1. marketingskills by Corey Haines
What it is: a library of 50+ marketing skills covering CRO, copywriting, copy editing, email sequences, cold email, SEO audits, programmatic SEO, schema, AI SEO, pricing, launches, referrals, ads and analytics.
Why it stands out: it includes a product-marketing skill that builds a context document (product, audience, positioning) which the other skills read. Write it once and every later skill starts with your context instead of a blank slate.
Install:
# All skills
npx skills add coreyhaines31/marketingskills
# Only the ones you want
npx skills add coreyhaines31/marketingskills --skill cro copywriting
# As a Claude Code plugin (inside Claude Code)
/plugin marketplace add coreyhaines31/marketingskills
/plugin install marketing-skillsBest for: SaaS and B2B marketers who want one pack that covers most of the funnel.
2. Anthropic’s official Marketing plugin
What it is: part of Anthropic’s knowledge-work-plugins. It ships 5 skills (content-creation, campaign-planning, brand-voice, competitive-analysis, performance-analytics) and 7 commands: /draft-content, /campaign-plan, /brand-review, /competitive-brief, /performance-report, /seo-audit and /email-sequence.
Why it stands out: it is designed to work with connectors such as Slack, Canva, Figma, HubSpot, Amplitude, Notion, Ahrefs, SimilarWeb and Klaviyo, so reports can pull real numbers rather than pasted ones.
Install:
claude plugin marketplace add anthropics/knowledge-work-plugins
claude plugin install marketing@knowledge-work-pluginsBest for: in-house teams who want a supported baseline and a brand-review step before anything ships.
3. claude-seo by AgriciDaniel
What it is: an SEO plugin with commands such as /seo audit <url>, /seo page, /seo technical, /seo schema, /seo geo (AI Overviews and generative engine optimization), /seo content-brief, /seo cluster and /seo local. It can connect to Google Search Console, PageSpeed, CrUX and GA4.
Install (needs Claude Code 1.0.33 or newer):
/plugin marketplace add AgriciDaniel/claude-seo
/plugin install claude-seo@agricidaniel-claude-seo
/seo setup/seo setup creates its own Python environment and a headless browser. Run /seo doctor to confirm it is ready.
Best for: marketers who own organic search. Deeper coverage is in Claude Code skills for SEO and skills for SEO audits.
4. claude-skills by Alireza Rezvani (marketing bundle)
What it is: a large MIT library across engineering, product, finance and more. The marketing-skill/ folder holds roughly 50 skills in eight groups: content, SEO and AEO, local SEO, CRO, channels, growth, intelligence and sales.
Install:
/plugin marketplace add alirezarezvani/claude-skills
/plugin install marketing-skills@claude-code-skillsBest for: teams who want one vendor-neutral library that also works in Codex, Gemini CLI and Cursor.
5. claude-blog by AgriciDaniel
What it is: a blog production suite with /blog write <topic> and /blog rewrite <file>, plus sub-skills for briefs, calendars and strategy. It targets both Google rankings and AI citations and includes a Python quality-scoring script.
Install:
/plugin marketplace add AgriciDaniel/claude-blogThe maintainers suggest cloning and pinning a release tag if you prefer the manual install.sh route. Python 3.11+ is needed for scoring.
Best for: content writers. See also skills for content writers.
6. seomachine by Craig Hewitt
What it is: a full Claude Code workspace, not a single skill. You clone the repo and open Claude Code in its root, and slash commands such as /research, /write and /optimize become available. Write-ups describe integrations with GA4, Search Console, DataForSEO and WordPress publishing.
Install:
git clone https://github.com/TheCraigHewitt/seomachine.git
cd seomachine
pip install -r data_sources/requirements.txt
claudeBest for: someone running a content program who is happy to work inside a dedicated folder.
7. awesome-claude-skills by Composio (directory)
What it is: a curated list, not one skill. Marketing-relevant entries include Competitive Ads Extractor, Lead Research Assistant, Content Research Writer, Brand Guidelines and Twitter Algorithm Optimizer, plus Composio app automations for Mailchimp, Klaviyo, HubSpot, Shopify and Google Analytics.
Install: copy the skill folder you want into ~/.claude/skills/ (personal) or .claude/skills/ (project), check it has a SKILL.md, and restart Claude Code. App automations need a Composio API key.
8. Anthropic’s official skills repo
What it is: Anthropic’s example skills, including document skills (docx, pptx, xlsx, pdf) and brand guidelines. The docx, pdf, pptx and xlsx skills are source-available under Anthropic’s own terms, not open source; the example skills are Apache-2.0. Not marketing-specific, but the pptx and docx skills are what turn a campaign plan into a deck your boss will open.
Install:
/plugin marketplace add anthropics/skillsThen pick the plugin you want from the list Claude shows.
Paid Claude Code skills: are they worth it?
Paid skill packs exist, but for marketing work none we found clearly beats the free packs above on coverage or maintenance. What you pay for is usually curation, convenience or a bundled workflow, not capability.
Here is what we could verify.
KissMySkills
A catalog of 2,500+ skills, prompts and agents delivered through a connector. Its homepage lists the catalog at $9 a month or $59 a year, an AI CRM at $15 a month, and both at $19 a month, cancel anytime.
AgentStack Power Pack
Pitched as “a Claude Code workflow OS for solo founders.” Third-party search snippets mention a launch price, but we could not confirm the current price from the page itself, so: pricing not public in a form we could verify. Check the page before buying.
Claudecademy Essential (Gumroad)
A Gumroad starter pack. $167 one-time (from the listing’s price data, checked 1 Nov 2026).
SaaS vendors that ship skills or MCP servers
Several marketing tools now plug into Claude through connectors or MCP servers rather than selling skills. Anthropic’s Marketing plugin lists HubSpot, Ahrefs, SimilarWeb, Klaviyo, Canva and Figma among its connectors. The skill is free, but the data behind it requires your existing paid account with that vendor.
Free vs paid: side by side
| Factor | Free open-source packs | Paid packs and catalogs |
|---|---|---|
| Price | $0 | $9/month to one-off purchases; some pricing not public |
| Can you read the code first? | Yes, on GitHub | Often only after purchase |
| Update signal | Public commit history | Seller’s word |
| Marketing coverage | Broad (50+ skills in top packs) | Varies; often generic |
| Support | GitHub issues, community | Seller support, sometimes refunds |
| Risk | Low if you read SKILL.md and scripts | Higher: unseen scripts run locally |
| Best for | Almost everyone | People who value curation over setup time |
Red flags before you pay
- No file preview or sample
SKILL.md. - Countdown timers or “price goes up tomorrow” claims you cannot verify.
- Skill counts in the hundreds with no list of what they are.
- Scripts that ask for API keys without saying where they are sent.
Where to find more marketing skills (directories and marketplaces)
Directories help you discover skills. They do not vet them, so read the source either way. These are the ones worth bookmarking.
| Directory | What it is | Cost to browse |
|---|---|---|
| skills.sh | The directory behind the npx skills CLI (Vercel Labs) | Free |
| claudemarketplaces.com | Independent index of skills, plugins and MCP servers with install commands and install counts | Free |
| cultofclaude.com | Large marketplace index; its title lists 39,000+ skills | Free |
| claudskills.com | Claude Code skills catalog | Free to browse |
| kissmyskills.com | Paid catalog (see above) | $9/month or $59/year |
| skillsmp.com | Skills marketplace index (blocks automated checks, so we could not verify contents) | Free to browse |
| Anthropic plugin marketplaces | anthropics/knowledge-work-plugins, anthropics/skills | Free |
A practical search habit: on any directory, filter by the GitHub owner you already trust (for example coreyhaines31 or anthropics), then check the repo’s last commit before installing.
How to install Claude Code skills (three ways)
You can install a skill with the npx skills CLI, as a Claude Code plugin, or by copying the folder yourself. All three end in the same place: a folder with a SKILL.md that Claude reads.
| Method | Command | Where it lands | When to use |
|---|---|---|---|
| skills CLI | npx skills add owner/repo | .claude/skills/ or ~/.claude/skills/ | Fastest; pick individual skills with --skill |
| Plugin | /plugin marketplace add owner/repo then /plugin install name | Managed by Claude Code | Packs with commands, hooks or agents |
| Manual | git clone then copy the folder | ~/.claude/skills/<name>/ | You want to read and edit first |
Personal or project? Put a skill in ~/.claude/skills/ to use it everywhere. Put it in .claude/skills/ inside a project folder to share it with your team through git, so everyone writes in the same brand voice.

A marketing workflow that chains these skills
The value shows up when skills hand work to each other: research feeds positioning, positioning feeds copy, copy gets a brand review, and the result is measured. Here is one chain using only free skills from this list.
Step 1: set context once
Run the product-marketing skill from marketingskills. Answer its questions about product, audience, pains and proof. It saves a context file other skills read.
Step 2: research the market
/competitive-brief(Marketing plugin) for positioning against named rivals.customer-research(marketingskills) to synthesize interviews, reviews or support tickets you paste in./seo cluster <keyword>(claude-seo) to map the topics your buyers search.
Keyword work gets its own guide: Claude Code skills for keyword research.
Step 3: plan the campaign
/campaign-plan (Marketing plugin) turns the research into objectives, channels, a calendar and success metrics.
Step 4: produce the assets
| Asset | Skill |
|---|---|
| Landing page copy | copywriting, then cro (marketingskills) |
| Blog post | /blog write (claude-blog) or /write (seomachine) |
| Email nurture | /email-sequence (Marketing plugin) or emails (marketingskills) |
| Ads | ad-creative (marketingskills) |
| Schema | schema (marketingskills) or /seo schema (claude-seo) |
| Deck for stakeholders | pptx skill (anthropics/skills) |
Copywriters will want the deeper list in skills for copywriters.
Step 5: review before shipping
/brand-review checks each asset against your voice and messaging pillars. Then copy-editing tightens it. A human still reads the final draft. Skills catch drift, they do not replace judgement.
Step 6: measure and loop
/performance-report builds the report, and if you connect analytics it can use real numbers. Feed what you learn back into the context file from step 1.
One prompt to kick it off
Use product-marketing context. Run a competitive brief on [Competitor A] and [Competitor B],
then a campaign plan for [launch name] targeting [ICP]. Draft the landing page with the
copywriting skill, run a CRO pass, then a brand review. Stop and show me each stage.“Stop and show me each stage” matters. Chained skills compound mistakes as fast as they compound good work.
Common mistakes marketers make with Claude Code skills
Most problems come from installing too much, skipping context, or trusting output without review. Avoid these.
- Installing every skill at once. Overlapping skills (three different “SEO writer” skills) compete for the same task. Start with one pack, add gaps later.
- Skipping the context step. Without product and audience context, every skill writes generic copy.
- Not reading
SKILL.md. It takes two minutes and tells you what the skill will do, which scripts it runs and what it needs. - Treating stars as quality. A popular repo can still be wrong for your channel.
- Leaving skills un-updated. Run
npx skills addagain or update the plugin when the repo moves. - Publishing without a human pass. Skills reduce rework. They do not check facts about your product.
- Paying for a pack before trying free ones. Try the free packs for a week first.
When nothing fits, build your own. It is a Markdown file with a name and description in frontmatter: how to build a Claude Code skill.
FAQ
What are Claude Code skills?
Folders containing a SKILL.md file with instructions (and sometimes scripts or templates) for a specific task. Claude reads each skill’s description and loads the full skill when a request matches.
Do I need to know how to code to use Claude Code skills?
No. You need to open a terminal and paste an install command. The skills themselves are written in plain Markdown.
What are the best Claude Code skills for marketing?
For most marketers: coreyhaines31/marketingskills, Anthropic’s Marketing plugin and claude-seo. Add claude-blog or seomachine if content is your main channel.
How do I install Claude Code skills?
Use npx skills add owner/repo, install a plugin with /plugin marketplace add owner/repo and /plugin install, or copy a skill folder into ~/.claude/skills/.
Where are Claude Code skills stored?
Personal skills live in ~/.claude/skills/. Project skills live in .claude/skills/ inside the project. Plugin skills are managed by Claude Code.
Are Claude Code skills free?
Most are. The free packs on this list are open source, except Anthropic’s document skills (docx, pdf, pptx, xlsx), which are free to use but source-available. Paid catalogs exist, such as KissMySkills at $9 a month.
Are paid Claude Code skill packs worth it?
Rarely for marketing right now. The best free packs are broader and update more often. Pay only if you can preview the files and the curation saves you real time.
Can I use Claude Code skills in Claude.ai or the API?
Yes. Anthropic supports skills across Claude apps, Claude Code and the API, though plugin commands are a Claude Code feature.
What is the difference between a skill and a plugin?
A skill is one capability. A plugin is a package that can bundle several skills plus slash commands, agents, hooks and connectors.
What is the difference between a skill and an MCP server?
A skill tells Claude how to do a task. An MCP server gives Claude access to a tool or data source, such as your CRM or analytics. They work well together.
Is Anthropic’s Marketing plugin any good?
It is a solid baseline for campaign planning, brand review and reporting, and it is maintained by Anthropic. It is less deep on CRO and SEO than marketingskills or claude-seo.
Are Claude Code skills safe to install?
Treat them like any code from the internet. Read SKILL.md and any scripts before installing, prefer active repos with public history, and be careful with skills that request API keys.
Can Claude Code skills write in my brand voice?
Yes, if you give them a brand voice document. The Marketing plugin’s brand-voice skill and /brand-review are built for this.
How many skills should I install?
Start with one pack and two or three focused skills. Add more only when you hit a gap, since overlapping skills can trigger on the same task.
Can Claude Code skills connect to HubSpot or Google Analytics?
Through connectors or MCP servers, yes. Anthropic’s Marketing plugin lists HubSpot and Amplitude, claude-seo connects to GA4 and Search Console, and Composio offers app automations.
Can I build my own marketing skill?
Yes. Create a folder with a SKILL.md containing a name, a description and your instructions. Anthropic’s skill-creator skill can scaffold one for you.
Sources and methodology
Repo stars, licences and last-push dates came from the GitHub API on 1 November 2026. Install commands and skill lists came from each repo’s README. Prices came from each vendor’s own page on the same date; where a price was not visible, we wrote “pricing not public.”
