The 10 skills that turn Claude Code into a marketing team

Star counts below were pulled from GitHub on October 2, 2026, so they will be higher by the time you read this. The list covers five jobs: research what your audience cares about, write copy that sounds human, get found on search, audit your funnel and show up on LinkedIn. You don't need all 10. Start with the job that is slowing you down most.

1. last30days: know what your audience cares about this month

mvanhorn/last30days-skill

63,382 stars on October 2, 2026. MIT license.

What it does: a research skill that searches Reddit, X, YouTube, TikTok, Hacker News, Polymarket, GitHub and more in parallel, scores results by what real people engaged with, and writes one brief about the last 30 days. Use it before you post, before a sales call, or to find topics that are taking off.

How to install it: inside Claude Code, type:

prompt/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days

Then run it on any topic:

prompt/last30days what's exploding in AI agents?

2. Humanizer: copy that reads like a person wrote it

blader/humanizer

53,603 stars on October 2, 2026. MIT license.

What it does: rewrites AI-written text so it sounds like a person wrote it, without changing what it says. It is built on Wikipedia's "Signs of AI writing" guide and checks for 26 patterns, like "it's not just X, it's Y" and one-line closers such as "let that sink in". It does not invent facts: if a sentence needs a missing detail, it asks you.

How to install it: inside Claude Code, type:

prompt/plugin marketplace add blader/humanizer
/plugin install humanizer@humanizer

The README says this needs Claude Code 2.1.142 or newer. On older versions, use:

bashnpx skills add blader/humanizer --global --agent claude-code

Then paste a draft. Add 2 or 3 paragraphs of your own writing and it will match your voice:

prompt/humanizer

Here's a sample of my writing for voice matching:
[paste 2-3 paragraphs of your own writing]

Now humanize this text:
[paste AI text to humanize]

Common questions

  • Are these 10 marketing skills free?

    Yes. All 10 are free to install. Some features connect to paid services you bring yourself: last30days uses a ScrapeCreators key for TikTok, Instagram and LinkedIn data, Claude SEO has optional paid data extensions like DataForSEO and Ahrefs, and LinkedIn Skills can use Apify and Publora. Every skill also uses your normal Claude usage.

  • Which one should I install first?

    Humanizer if you already write with AI, because it improves everything you publish. last30days if you don't know what to post yet, because it shows you what your audience is talking about right now.

  • Will the LinkedIn skills post for me?

    Not by default. Both LinkedIn repos draft content for you to paste. LinkedIn Skills can auto-post through Publora if you connect it, but automating your LinkedIn account can break LinkedIn's terms and risk the account, so copy-paste is the safer route.

  • Will Humanizer get my writing past AI detectors?

    That is not what it is for. Humanizer makes writing clear and natural for people to read. Its own README says detectors still flag most of its output.

  • Do I need to know how to code?

    No. Most of these install with one or two commands you paste into Claude Code, and then you talk to them in plain English, like "audit this page" or "write me a LinkedIn post about my launch".
