Claude Skills for Marketers: 6 to Upload Today

A marketer produces the same five things on a loop: a voice everything is checked against, a brief before a post, derivatives after it, a page for the campaign, and the emails that follow. Each one is a procedure, and a procedure is exactly what a Claude skill holds. This guide covers the mechanism in one paragraph, the upload steps, five skills built for marketers, Anthropic's document skills as the sixth, and the Claude Code commands and agent that go with them.

What a skill is, in one paragraph

A skill is a folder containing a SKILL.md file: a short description of when it applies and a set of instructions for how to do the job. Claude sees only the description at the start of a session and loads the full instructions when your request matches it, or when you call it by name. That is why a skill costs nothing until it is needed and why you can have dozens installed. The longer explanation, including how skills differ from Projects and custom instructions, is What Are Claude Skills?. Every skill below is pure instruction: no scripts, no network, no repository. That is deliberate, because it means the identical file runs on claude.ai, in Cowork, and in Claude Code, and it means the whole skill is the text you can read on its page before you upload it.

Uploading on claude.ai

The steps above are Anthropic's, from its skills article as of September 2026. The one that trips people is the folder name: the folder inside the ZIP must be named exactly after the skill, so brand-voice-profiler/SKILL.md, not skill/SKILL.md. Skills are available on Free, Pro, Max, Team, and Enterprise once code execution is on, and an enabled skill also applies in Cowork and the Microsoft 365 add-ins. If you are on Claude Code instead, the same folder goes in .claude/skills/ inside your project; How to Install Claude Skills covers every surface.

The six skills

1. brand-voice-profiler

Build this one first. brand-voice-profiler reads a set of your best pieces and produces a written brand voice document: tone attributes with evidence, sentence-level habits, vocabulary to use and to avoid, and before-and-after pairs. Save the output; the next four skills and the brand-check command all measure against it.

Use brand-voice-profiler on these six posts: [paste]. Produce the
voice profile with ten banned phrases and the reason for each, and
three before/after pairs taken from the posts themselves.

How to keep the profile current and test it against new drafts is in Brand Voice with Claude Skills.

2. seo-content-brief-writer

seo-content-brief-writer turns a target query plus whatever data you paste (a Search Console export, a competitor's outline, a term list from your optimization tool) into a brief: intent, angle, outline with the questions each section answers, internal links to include, and what would make the piece different from what already ranks.

Use seo-content-brief-writer. Target: "marketing attribution models".
Here are our current queries for the topic and the top three ranking
outlines: [paste]. Flag anything I have not given you as an open
question rather than guessing.

The full pipeline from export to published post is in SEO Content Workflow with Claude Code.

3. content-repurposer

content-repurposer takes one long piece and produces the derivatives you name, each with its own length and format rules, without inventing examples the source does not contain.

Use content-repurposer on this post: [paste]. Outputs: a five-post
LinkedIn sequence, a newsletter section under 200 words, and three
hooks under 280 characters. Apply this voice profile: [paste].

4. landing-page-copywriter

landing-page-copywriter writes the blocks of a campaign page from a brief: headline options, subhead, the problem-and-outcome section, proof, objections, and the call to action, each labeled so a designer or a page builder can place them.

Use landing-page-copywriter. Audience: finance leads at mid-market
SaaS. Offer: a live webinar on month-end close automation. CTA:
register. Three headline options; mark any claim that needs a source.

5. email-sequence-drafter

email-sequence-drafter drafts a multi-email sequence, one message per section with subject line, preview text, body, send timing, and the exit condition, in the voice you give it.

Use email-sequence-drafter. Sequence: webinar registrant, four emails
(confirmation, two reminders, replay). Voice profile: [paste]. Keep
each body under 150 words.

6. Anthropic's document skills

The sixth is built in. Anthropic ships skills for Word, Excel, PowerPoint, and PDF creation, and the support article lists them as enhanced spreadsheet creation, professional Word documents, presentation generation, and PDF processing. Ask for the brief as a .docx or the campaign report as a .pptx and the relevant skill loads. What each produces and where they fall short is in Claude Document Skills.

For Claude Code users: two commands and an agent

Inside Claude Code the same jobs are faster when the input already lives in the folder. Anthropic's docs note that "custom commands have been merged into skills," so a file in .claude/commands/ and a skill folder both create a slash command. /repurpose reads a post from the repo and writes each derivative as its own file, and /brand-check runs a draft against your voice file and reports deviations by severity.

The content-editor agent is different in kind: a subagent with its own instructions that reads a draft and returns every unsupported claim, every statistic without a source, and every sentence that breaks the voice profile. Run it before a human editor does. The differences between skills, commands, and agents are in Skills vs Agents vs Commands, and how all of this fits into a content repo is the marketers pillar.

Making them yours

All five are starting points. The third time you correct the output the same way, that correction belongs in the file: your persona names, your CTA conventions, the sections your briefs always have. Edit the SKILL.md, re-zip, re-upload. Anthropic's marketing plugin, covered in Anthropic's Marketing Plugin: A Guide, overlaps with two of these and adds campaign planning, competitive briefs, and reporting; the rest of the toolkit is at the marketers hub.
