What skills even are
If you haven't touched skills yet, here's the 60-second version. Skills are little packages of instructions and code that teach Claude how to do a specific job really well — writing sales copy, generating slides, stripping AI-sounding phrases, whatever. You install one, and Claude knows when to use it automatically based on what you're doing.
Think of it like hiring specialists for your AI. Instead of re-explaining "how we do things here" every single time, the skill does the heavy lifting for you.
Where skills live
Skills are folders stored at ~/.claude/skills/ on your machine. Each one has a SKILL.md file that tells Claude what it does and when to use it. You can install them by cloning the GitHub repo into that folder, or by dropping the folder in manually. Each skill is self-contained — delete the folder, it's gone.
The eight below are the ones I actually reach for. Some are official Anthropic skills (safe to install anytime). Three are from the community — still great, but worth reading before you run (more on that at the end).
The official Anthropic ones
These five live in the official anthropics/skills repo. Anthropic maintains them, which means they're safe to install anytime without reading the source code. Start here.
Skill Creator
The meta one. Helps Claude build its own skills based on how you actually work. If you only grab one, grab this — it unlocks every other skill you'll ever want to make.
→ Install on GitHubTheme Factory
Keeps your outputs on-brand every single time. 10 pre-set themes plus generates new ones on the fly. Slides, docs, HTML, reports — all consistent, all the time.
→ Install on GitHubFrontend Design
If you're generating anything visual — components, landing pages, artifacts — this is what stops it looking like a 2016 PowerPoint. Non-negotiable for any frontend work.
→ Install on GitHubDocument Skills (×4)
The bundle that turns Claude into a proper deliverables machine. Word docs with actual formatting, real PowerPoint decks, spreadsheets with formulas, PDFs you can send to clients. Install all four.
→ Install on GitHubBrand Guidelines
Pairs beautifully with Theme Factory. Locks in your specific brand identity — colours, fonts, voice — so every output actually looks like it came from your business, not from Claude's default aesthetic.
→ Install on GitHubMy honest pick
If you can only install one to start: Skill Creator. It's the only one that makes you more capable over time — because it teaches Claude to build new skills for whatever you need next. After that, add Theme Factory + Brand Guidelines together. Then Document Skills when you're ready to produce client-ready deliverables.
The community ones worth trusting
These three aren't from Anthropic — they're built by community members. I've vetted each one (read the SKILL.md, checked the author, tested it myself). If you're installing community skills, these are three I'd happily recommend.
Stop Slop
Strips the AI-tell patterns out of your writing. No more "I'd love to help you with that" or "let's dive in." Went viral for a reason — if you're writing with Claude (emails, captions, blog posts, anything), you need this. It catches the hedging, the over-explanation, the corporate-speak — and rewrites it to sound like a human wrote it.
→ Install on GitHubMarketing Skills by Corey Haines
30+ marketing-focused skills in one pack. CRO reviews, copywriting, positioning, competitor research, campaign planning. This one is epic — it's basically a whole marketing team in skill form. If you do any kind of marketing work (your own business or clients'), this pack alone is worth the setup time for the whole skills system.
→ Install on GitHubThe Antislop
Second option if you want alternatives to Stop Slop. 35+ patterns, a scoring system, and comes with a voice-analyzer that learns your actual writing style. More thorough if you're a writing nerd. Pick this or Stop Slop — you don't need both.
→ Install on GitHubHow I actually stack these together
Installing skills is pointless if you don't know how they work together. Here are the combos that do the heavy lifting in my business.
Stack 1: The on-brand-for-life trio
Why it works: Set these up once and every document, deck, and landing page you generate from that point forward looks on-brand with zero extra prompting. Genuine compounding return on 15 minutes of setup.
Stack 2: The client-deliverables machine
This is my "I need to send something to a client" stack. Want a branded PowerPoint deck? Claude builds it using Document Skills (real .pptx, not a fake one), styled by Theme Factory, brand-locked by Brand Guidelines.
Want a landing page? Frontend Design handles the visual polish. Same brand rules, same quality bar, different format. The whole stack acts like one coherent design system.
Stack 3: The writing stack
Why it works: Marketing skills handle the what to say. Stop Slop handles how to say it without sounding like ChatGPT. Together = emails, captions, and sales copy that move the needle without screaming AI.
If you're overwhelmed
Don't install all 8 at once. Start with Skill Creator. Live with it for a week. Add Theme Factory + Brand Guidelines next. Live with those. Layer the rest in slowly. Skills overlap — installing too many at once means Claude gets confused about which to use.
Before you install anything — read this
Here's the part nobody tells you about skills: they can execute code on your machine. That's what makes them powerful — but it also means installing a random skill from the internet is a bit like running a script you didn't write. You need to know what it's doing.
Don't panic — this isn't as scary as it sounds. Follow these three rules and you're fine:
Rule 1: Anthropic's official skills are always safe
Anything inside the anthropics/skills repo on GitHub has been vetted by Anthropic. Install freely. Skills 1, 3, 5, 6, 7 on this list are all from that repo.
Rule 2: For community skills, read SKILL.md first
Open the repo. Read the SKILL.md file. It tells you what the skill does and when Claude will use it. If there's a Python file in there, skim that too — you don't need to understand every line, but you should recognise what it's doing at a high level (fetching data? reading files? calling an API?). If you don't understand what it's doing, don't install it.
Rule 3: Stick to skills from people with a public reputation
Corey Haines has a known name in marketing. The Stop Slop and Antislop creators are active in the community. That's not a guarantee, but it's a massive filter — someone with a reputation to protect is far less likely to ship something malicious. Skills from random anonymous accounts? Skip.
The short version
Anthropic repo = safe, install anytime. Community skills = open SKILL.md, read it, then decide. If in doubt, don't install. You can always come back to it later.
