What are Claude Code Skills

A Claude Code Skill is a plain English file that teaches Claude how to do one of your jobs. There's no code in it and nothing to program: you write instructions the way you'd brief a person, and Claude reads them and does the work.

━━━━━━━━━━━━━━━━━━━━━━

WHAT CHANGES WHEN YOU HAVE ONE 🔁

▶ Without a Skill: you explain the job to AI from scratch every time, and the explanation dies when the chat closes.

▶ With a Skill: the explanation lives in a small file called SKILL.md. Claude reads it every time the job comes up, so the work comes out right today and right next month, even while you're busy with something else.

That's the whole shift. The instruction stops being something you type and becomes something you own.

WHAT'S ACTUALLY IN THE FILE 📄

Four things, in plain English: the Skill's name, what it does, when to use it, and the steps to follow. Here's the shape of one:

▶ Name: draft the newsletter

▶ What it does: turns this week's notes into a first draft

▶ When to use: every Friday

▶ Steps: read the notes file, write 600 words in my voice, save the draft for my review

That's a complete Skill. If you can write a clear note to a person, you can write one, and that's by design: Anthropic built Skills so the instruction language is English. The file sits in a folder in your project, and Claude Code reads it in Claude Desktop or in VS Code, whichever you use.

WHY PEOPLE BOTHER 🧭

Because one Skill is a saved job, and a few Skills chained together are a running system. People here use them to automate their own work, run a small business's busywork, and build things they own. The full stack behind all of it is a laptop and a Claude Code subscription, nothing else.

WRITE YOUR FIRST ONE TODAY ✍️

Pick the job you repeat most and write those four lines in any text file: name, what it does, when, steps. That note is your first SKILL.md in draft, and turning it into a running Skill takes an afternoon, not a course in programming.

If you found this page from a search: it lives inside Agent Skills Academy, free to join, and the free Foundation class walks you from that note to your first running Skill, step by step.

Finish this line below: the job I explain most often at work is ___. That's the job your first Skill should do.
