Claude skills are saved instructions that teach Claude to do one job, such as writing copy or auditing a page, the same way every time. The 14 Claude skills in this guide are the best Claude agent skills for marketing that I have personally used, across product marketing, SEO, AEO (getting cited in AI answers), outreach, email marketing, content and design.
2 of my 14 picks, skill-creator and Superpowers, help you build your own Claude skill for a complex task from a simple prompt.
This guide covers how I tested each pick, which 14 Claude skills are the best and where to find more Claude skills on GitHub. To learn what Claude skills are, how to install them and how to write your own, read my Claude skills guide.
How Did I Test These Claude Skills?
For each of the 14 best Claude skills in this list, I read its SKILL.md and README on GitHub, checked its GitHub stars and skills CLI installs, and, where I could, used it on a real marketing task.
- README: the guide file shown on the main page of a GitHub repo (short for repository), the online folder that holds a project's files.
- GitHub stars: bookmarks that GitHub users add to a repo, so a star count is a rough sign of how popular the whole repo is, not one skill inside the repo.
- Skills CLI installs: the number of times a skill was installed with the skills CLI, the command-line tool behind skills.sh, a public directory and leaderboard of agent skills. CLI stands for command-line interface, a way to run a program by typing commands in a terminal, the command window.
I tested these Claude skills mainly in my daily marketing work at TestMu AI, inside Claude Code on my Windows 11 machine. I also ran hands-on tests on my own site, such as my free marketing tools page and my homepage.
Claude skills I already had ran from my installed copies, and I loaded every other skill I tested straight from the SKILL.md in its GitHub repo, without installing it.
For each hands-on test, I noted whether the skill changed Claude's output, what setup the skill needed and who should install the skill.
I picked the 14 best Claude skills in this guide from more than 50 of the most popular and most discussed Claude skills I have tried in my daily marketing work.
Below is the Reddit discussion thread on the best Claude skills, which I used for research, on the topic "Drop your best Claude skills in here!" from the r/ClaudeAI community.
Reddit discussion in r/ClaudeAI: Drop your best Claude skills in here!
Discussion: People posted the skills they use most, and the main debate was Superpowers against GSD, another Claude Code workflow: GSD for large, complex projects, slower but more thorough, and Superpowers for smaller well-defined work, faster, with the best brainstorming.
Conclusion: Choose by project size. An end-of-session /close skill that updates memory, commits and writes a session log was a popular pattern, and the Caveman token-saving skill was called overhyped because it only trims output tokens.

The 14 best Claude skills, one for each job, are product-marketing, copywriting, brand-review, seo-audit, Claude SEO, Cold Outbound Skills, cro, lead-magnets, ai-seo, marketing-plan, UI UX Pro Max, Impeccable, Superpowers and skill-creator.
1. Best Claude skill for product marketing: product-marketing
- What it does: The product-marketing skill writes one product marketing context file for your business: a document that describes your product, audience, competitors, positioning, voice and proof.
- Where to use it: You can use product-marketing to write one context file about your product before you run any other marketing skill, because Corey Haines' other Claude skills for product marketing read that file first. Pick "Auto-draft from codebase" in product-marketing to build the context file from your project's files, then correct what the draft gets wrong.
- Why it's the best: The product-marketing skill has 71.9K skills CLI installs, and its repo, Corey Haines' marketingskills, has 52.2K GitHub stars (Oct 2026). I used product-marketing to auto-draft the context file for my own website, and it filled 25 of the file's 41 fields from my site's code, so I started from a draft instead of a blank page.

- What it does: Corey Haines' copywriting skill writes or rewrites the copy for a marketing page, including the headline, subheadline, calls to action and each section, with alternatives to choose from.

- Why it's the best: The copywriting skill is the most-installed copywriting skill on skills.sh, with 213.5K skills CLI installs, and its repo has 52.2K GitHub stars (Oct 2026). I used copywriting to draft a new intro for my free marketing tools page, and its first draft put the phrase "free marketing tools" into the main heading and opened with a clear one-line definition.

- Where to use it: You can use Cold Outbound Skills to plan, write and send B2B cold email campaigns, starting with the /cold-email-kickoff command in Claude Code. Cold Outbound Skills works best once you have your own sending domains and warmed-up inboxes that email providers trust.

- What it does: Corey Haines' cro skill audits one page or form for conversions by checking the value proposition, headline, calls to action, trust signals, objections and friction, then returns quick wins and A/B test ideas.
- Where to use it: You can use cro to get more sign-ups or sales from one landing page, pricing page or form: give cro the page URL and the one action you want visitors to take.
- Why it's the best: The cro skill has 75.8K skills CLI installs, and its repo, Corey Haines' marketingskills, has 52.2K GitHub stars (Oct 2026). I ran cro on my homepage, and in one pass it showed me that the black "Start conversation" button in my header outweighs my main "Get free site audit" button, and that no proof sits on my first screen.
npx skills add coreyhaines31/marketingskills --skill cro --agent claude-code8. Best Claude skill for lead magnets: lead-magnets
- What it does: Corey Haines' lead-magnets skill plans a lead magnet (a free resource people get for their email address): the format that fits the buyer's stage, whether to ask for an email before the download, the form fields, the landing and thank-you pages, promotion and what to measure.
- Where to use it: You can use lead-magnets to plan a new checklist, template, ebook or quiz, or to fix a lead magnet that is not getting enough sign-ups.

I ran lead-magnets on the sign-up card for my free AI Product Marketing Playbook, and in a single run it listed what the card was missing: a line on what's inside, a preview and social proof.

The marketing-plan skill turns scattered work, such as SEO research, brand voice docs and audits, into one plan in the right order, so you don't have to stitch the pieces together yourself.
npx skills add coreyhaines31/marketingskills --skill marketing-plan --agent claude-code11. Best Claude skill for UI/UX design: UI UX Pro Max
- What it does: UI UX Pro Max gives Claude a searchable design database of 79 styles, 192 colour palettes, 74 font pairings and 119 UX (user experience) rules. UI UX Pro Max creates a full design system (layout, style, colours and fonts) before Claude writes any code.

- Why it's the best: UI UX Pro Max has 132.5K GitHub stars and 379.7K skills CLI installs (Oct 2026). I used UI UX Pro Max to design my own website, and it gave me a ready starting point: a full design system and an accessibility checklist before Claude wrote any code.
npx skills add nextlevelbuilder/ui-ux-pro-max-skill --skill ui-ux-pro-max --agent claude-code12. Best Claude skill for design review: Impeccable
- What it does: Impeccable gives Claude 24 design commands, such as critique (a design review), audit (technical checks) and polish (a final pass). Impeccable also has 61 rules that flag design flaws and signs that AI made the design, such as purple gradients.

/impeccable initonce so Impeccable learns your product and saves the details in aPRODUCT.mdfile. - Why it's the best: Impeccable has 74K GitHub stars and 307.2K skills CLI installs (Oct 2026). I ran Impeccable on my free marketing tools page, and one of its written rules caught a real bug I had missed: with JavaScript turned off, the page intro and every tool card stayed invisible.
npx impeccable install13. Best Claude Code skill for development: Superpowers
- What it does: Superpowers is a development workflow of 15 skills that guides Claude Code through building software. Superpowers makes Claude brainstorm the design with you, write a test-first plan (a test before each task's code), then build the software task by task.
- Where to use it: You can use Superpowers to make Claude Code plan and test a software project before any code is written. Superpowers is overkill for a small fix.
- Why it's the best: Superpowers has 294.2K GitHub stars (Oct 2026), the most of any repo in this list. I used Superpowers to plan a new free UTM Builder for my site, and its writing-plans skill turned one request into a 5-task plan with exact file paths and a test written before each task's code.
/plugin install superpowers@claude-plugins-official14. Best Claude skill for creating your own skills: skill-creator
- What it does: The skill-creator skill builds a new Claude skill with you by asking what the skill should do and when Claude should use it, then drafting the
SKILL.mdfile. The skill-creator skill can also test a new skill by running the same prompts with and without the skill and comparing the results. - Where to use it: You can use skill-creator to turn any workflow or complex task that you repeat into your own Claude skill. The "Create with Claude" option in the Claude app and on claude.ai uses skill-creator.
- Why it's the best: The skill-creator skill comes from Anthropic's skills repo, which has 179.4K GitHub stars, and has 396.7K skills CLI installs (Oct 2026). I used skill-creator to build my own reddit-box skill, which turns a saved Reddit thread into the Reddit box on my blog posts, and skill-creator wrote the 97-line SKILL.md and 3 test prompts for me.

Claude skills best practices for installing from GitHub start with one rule: read a skill before you trust it.
A security audit of 3,984 agent skills from 2 public skill directories, ClawHub and skills.sh, found that 36.82% of the skills had at least one security flaw and 13.4% had a critical issue (Feb 2026).[1]
The 3,984-skill security audit also confirmed 76 malicious payloads, code built to install backdoors, send your data out or steal credentials such as passwords and API keys.
In Claude Code, the allowed-tools field in a SKILL.md file lets Claude use the listed tools without asking you for approval while the skill runs.[2] Claude Code's workspace trust check, which asks whether you trust a folder, does not stop a project skill saved in that folder from applying its allowed-tools field.
Note: Use Claude skills only from sources you trust, such as Anthropic or authors whose files you have read, and check every file that comes with a skill. Read every SKILL.md and script in a GitHub repo before you run Claude Code in it, because a project skill can grant itself broad tool access.
