What are AI skills?
An AI like Claude or ChatGPT is brilliant at thinking, but on its own it can't do much. Skills are how you give it hands.
The short version
An AI skill is a small program that an AI can use to do a job in the real world. The AI already knows how to talk about anything; a skill lets it act.
You can think of an AI without skills as a very smart person locked in a room with no internet, no phone, no files. They can answer your questions, but they can't reach out and do anything. A skill is a door in that room — one door per job.
What can skills actually do?
Some skills are tiny and do one thing. Others bundle a whole toolkit. Here are real examples from the iClaude catalog:
- Read PDFs — open a contract on your computer and ask Claude to summarise it.
- Search the web — Claude doesn't browse by default; a search skill lets it pull live results.
- Talk to your database — "list every customer from Nepal who signed up last month."
- Send WhatsApp messages — automate replies through your own WhatsApp Business number.
- Generate images — pipe a prompt straight to an image model and drop the file on your desktop.
- Edit your Notion or Google Docs — "add today's standup notes to the Engineering page."
- Run code in a sandbox — let the AI test its own Python without touching your machine.
There are 2,700+ of these in the iClaude catalog, and the number grows every week.
Where does iClaude fit in?
Think of iClaude as the app store for AI skills.
- Find — every skill in one searchable place, not scattered across GitHub.
- Install — one command and the skill is wired into your AI tool. No editing config files by hand.
- Trust — every skill is checked, ranked, and versioned. The catalog tells you what runs well and what doesn't.
Without iClaude, installing a skill usually means: read a README, copy a JSON snippet, paste it into the right config file in the right folder with the right syntax, restart the AI tool, hope it works. With iClaude:
npx iclaude install pdf-readerDone. The CLI figures out which tool you're using and writes the right config.
What do I need before I start?
Just Node.js. It's a free piece of software that runs the iClaude installer. If you've never installed it, the next tutorial walks you through it in 5 minutes.
You'll also need one AI tool to install skills into. That's usually Claude Desktop or Cursor. ChatGPT and n8n also work — pick whichever you already use.
Ready?
Next stop: install Node.js. If Node is already on your machine, jump straight to your platform: Claude Desktop, Cursor, ChatGPT, or n8n.
