Humanizer — Strip the AI Tells
The Humanizer skill (sometimes called Stop-Slop) forces Claude to remove every pattern that signals "AI wrote this." Em dashes, throat-clearing openers, hedging adverbs, sentence rhythms that read like a chatbot. All gone.
The rules are aggressive. No "It's not just X, it's Y" structures. No "Here's the thing." No "really," "just," or "actually." No closing summaries that restate the point. The output reads like a person typed it.
What it cleans up
- Em dashes and other typographic tells
- Filler phrases like "at its core," "in today's landscape"
- Hedging adverbs like "really," "honestly," "literally"
- Antithesis loops ("not X, but Y") that AI defaults to
- Restate-the-point conclusions that add nothing
Search: "stop-slop claude skill" on GitHub. Activate it before drafting any social post, email, or newsletter — Claude rewrites itself in real time.
Pro Move Stack this skill after a copywriting skill. Let the first skill write, then let Humanizer clean. Output reads sharper than most human writers.
Marketing Skills — A Full Team for Free
This is not one skill. It is a bundle of more than 20 specialized agents that cover every marketing function — SEO audits, copywriting, email sequences, ad creative, content strategy, popup CRO, paid ads, social content. Each one runs as its own slash command.
Treat it like hiring a 10-person marketing team that costs zero dollars and never sleeps. Run the SEO audit on your site, hand the report to the copywriting agent, pipe that into the email sequence builder, and ship a full funnel in an afternoon.
What is inside the bundle
- SEO Audit — diagnoses ranking issues
- Copywriting — page-level copy for any funnel stage
- Email Sequence — onboarding, nurture, and lifecycle flows
- Cold Email — B2B outreach that gets replies
- Ad Creative — bulk headlines and primary text
- Content Strategy — topic clusters and editorial plans
- Popup CRO, Page CRO, Signup Flow CRO
Search: "claude marketing skills" on GitHub. Joshua's open-source bundle ships all of these as a single folder you drop into ~/.claude/skills/.
Design — Make Anything Claude Builds Look Pro
The Design skill is the reason your landing pages, slides, and posters stop looking like an AI made them. It bundles design tokens, color systems, font pairings, layout rules, and component patterns into a single agent that every other build skill can call.
Plug it in once and every output gets better. Slides, dashboards, banners, logos, brand identity systems — all of them inherit the design layer. The shadcn integration and Tailwind defaults handle the production code, so what comes out is shippable, not just pretty.
What ships with the design skill
- 50+ visual styles (glassmorphism, brutalism, bento grid, minimal)
- 161 color palettes and 57 font pairings
- shadcn/ui and Tailwind component patterns
- Logo generation, banner design, icon design
- Corporate identity programs (50+ deliverables)
Search: "anthropic skills design" on GitHub or look inside the official anthropics/skills repo. The community version (ui-ux-pro-max) adds extra styles.
Stack It Run Design alongside Frontend-Design (skill #11 below). One handles tokens and rules, the other handles distinctive layout. The combo beats any solo tool.
Remotion — Claude Opens Its Own Video Editor
Remotion is a framework that lets you build videos in React code. The Remotion skill teaches Claude how to use it, so you can hand Claude a single text prompt and it returns a fully animated, production-ready video — no editing software, no timeline, no After Effects.
Think long-form explainers, motion graphics, ad creative, animated lyric videos, social hooks. Claude writes the React, renders the frames, and exports an MP4. The same skill scales from a 6-second TikTok hook to a 60-second product walkthrough.
What you can ship without touching a timeline
- Animated explainer videos with voiceover and captions
- UGC-style script reads with synthetic actors
- Motion-design SaaS ads
- Beat-synced music visuals
- Product turntables and 360 reveals
Search: "remotion claude skill" on GitHub. Install Node and Remotion CLI first, then drop the skill folder in ~/.claude/skills/.
Renders run locally and eat CPU. Start with short clips (under 30 seconds) before scaling up.

The Move
You do not need all 25 on day one. Install the top 5 first, run them for a week, then add the bonus skills as your workflow exposes gaps. The stack should grow with the work, not the other way around.
One Rule Every skill you install should replace a task you used to do by hand. If it does not save you at least an hour a week, uninstall it.
Install Your Stack This Week
Run these five steps in order. By Friday you will have all 25 skills wired in and a workflow that beats most agencies.
1
Open your skills folder
Find ~/.claude/skills/. Make it if it does not exist. This is where every skill lives.
2
Install the top 5 first
Research, Humanizer, Marketing Skills, Design, Remotion. These give you the biggest swing per minute installed.
3
Run each one once
A real task. Not a test prompt. Run Research on your competitor, run Humanizer on your last newsletter, run Design on a landing page. Confirm the output before moving on.
4
Add bonus skills by job-to-be-done
Need a deck? Install Slides. Need email triage? Install Inbox Manager. Match the skill to the next task on your list.
5
Stack them
The unlock is chaining. Research feeds Content Strategy, which feeds Copywriting, which feeds Humanizer. One prompt, four skills, ship-ready output.
Skill stacking is the leverage. A single skill saves time. A chain of skills replaces a workflow. Aim for chains.
