Every time you open Claude, do you type the same things over and over? Your business details, your tone, your rules, all from zero, every single time? There is a feature inside Claude that fixes this completely, and most people have never even turned it on. It is called Skills, and in this tutorial I will show you how to build your first one from scratch, with no coding needed.
What are Claude skills?
A Claude skill is a set of instructions you write one time. It covers how you like things done, what your rules are, and what the final result should look like. Claude saves it, and from that moment on, you never have to explain it again.
The easiest way to understand it is the recipe card analogy. Imagine your grandma has an amazing cookie recipe, but every Sunday you had to stand next to her and explain it from memory. How much flour, how much sugar, how long in the oven. Every single Sunday.
That would be crazy. That is why recipes go on a recipe card. You write it down once, put it in the kitchen drawer, and from that day on anyone can pull out the card and bake perfect cookies.
A Claude skill is exactly that. It is a recipe card for Claude. You write the instructions once, and Claude follows them every time.
Here is the part most people miss, and it is what makes Claude skills so clever. Claude does not read all your recipe cards all the time. They stay in the drawer.
Claude only opens a card when the task actually needs it. So you could have ten skills, or fifty skills, and Claude stays just as fast. It only grabs the one card that matters for the job in front of it.

Claude skills vs saved prompts
Compare skills to what most people do today. They keep a notes file somewhere with their favorite prompt, and they copy and paste it into Claude every time. Or worse, they retype it from memory and get slightly different results every day.
Skills end that completely. One card, written once, the same great result every time. And no, you do not need to be technical to make one.
Behind the scenes, a skill is just a small file with instructions in it. But you will never have to touch that file yourself, because Claude can build the whole thing for you. That is exactly what we will do in the steps below.
Skills also work hand in hand with good prompting habits. If you want to get better at giving AI clear instructions, our prompt engineering guide covers the basics in plain language.
How to create your first Claude skill in 5 steps
- Turn on code execution and file creation
- Find the Customize section
- Open the Skill Creator and describe your skill
- Feed it real examples, not vague descriptions
- Test your skill and keep improving it
1. Turn on code execution and file creation
Before anything else, there is one setting you need. If it is off, none of this works. The good news is that this takes about thirty seconds.
Open the Claude desktop app and go to Settings, then Capabilities. Scroll down until you find Code execution and file creation. This is the switch that matters. Turn it on.
Skills need this setting turned on to actually do their work. So if skills ever feel broken for you, this switch is the first place to check.
2. Find the Customize section
You do not have to start from an empty drawer. Look at the left sidebar in the Claude app. Right below Artifacts, you will see an option called Customize. Click it.
You will see three options in the middle of the screen:
- Connect your apps: this is for linking Claude to tools you already use.
- Create new skills: this is where you teach Claude your own way of doing things.
- Browse plugins: this is where the ready made stuff lives.
On the left side of this screen, you will also see a Skills tab. That is your drawer. Every skill you add or create shows up there, all in one place, so you always know exactly what Claude knows.
3. Open the Skill Creator and describe your skill
Click Create new skills. This opens the Skill Creator, and here is the beautiful part. The Skill Creator is itself a skill. It is a recipe card that teaches Claude how to write recipe cards.
Let me show you how this works with a real example that thousands of small business owners will instantly recognize.
Meet Sarah. Sarah is a wedding photographer, and every single week her inbox fills up with the same kind of email. "Hi, we are getting married next June, what are your prices?" Some emails are long, some are two lines, and some forget to mention the date or the venue.
Every time, Sarah types out the same reply from scratch. Her packages, her travel policy, her booking process, her friendly tone. Twenty minutes per email. And if she replies slowly or sounds cold, that couple books someone else. That is real money walking away.
So we build Sarah a skill. In the Skill Creator, we type something simple, like: "Build me a skill that replies to wedding photography inquiry emails."
Now watch what happens. Claude does not just go off and guess. It starts asking questions. Smart questions:
- What packages do you offer, and what do they cost?
- What is your tone, formal or friendly?
- What questions do you always ask the couple?
- What happens after they reply? Do you send a contract or book a call?
4. Feed it real examples, not vague descriptions
This is the golden rule of building Claude skills, so write it down: the better you feed it, the better it works.
Whatever you would tell a new assistant on their first day, that is what goes into the skill.
Do not make Claude guess your prices. Give it your real package list. Do not describe your tone. Paste in two or three real emails you have sent that sounded exactly like you.
Give it your booking link. Give it your answer for when a date is already taken. The more real material you provide, the closer the output will be to something you would actually send.
Once you answer the questions, Claude formats everything properly behind the scenes and saves the skill. Remember that technical file I mentioned earlier? You never saw it. Claude handled all of it. Your new skill now sits in your Skills tab, in the drawer, waiting.
5. Test your skill and keep improving it
Now comes the payoff. A new inquiry lands in Sarah's inbox. She copies it, pastes it into Claude, and types: "Reply to this inquiry." That is it.
Claude grabs the recipe card, reads the couple's email, notices they mentioned a beach wedding for eighty guests, picks the right package, asks the questions Sarah always asks, and writes the whole reply in Sarah's voice.
Twenty minutes of work, done in ten seconds. And it sounds like Sarah on her best day, every single time.
Once a skill is saved, you can keep making it better. Just tell Claude: "Update my skill, my prices changed," or "Add a rule that I do not shoot weddings in August." The recipe card gets smarter over time.
Now pause for a second and think about your own week. What is the one thing you explain to Claude over and over? A quote? A report? A weekly email? That is your first skill.
Whatever it is, the recipe is the same: open the Skill Creator, answer the questions, and feed it real examples. If you want more structured practice with Claude itself, take a look at these free Claude courses that walk you through the platform step by step.
What about plugins?
Building your own skills is not the only option. Claude also offers plugins, which you will find under Browse plugins in the Customize section.
Think of plugins as full recipe books instead of single cards. One plugin can contain a whole bundle of skills built around one job. For example, a marketing plugin can come packed with skills for content, campaigns, and reports.
Instead of adding skills one by one, you grab the whole book at once. One click, and it shows up in your sidebar under Personal plugins, ready to go.
Ready made plugins are a nice shortcut, but the real magic is still teaching Claude how you work. A plugin knows marketing in general. Your own skill knows your prices, your clients, and your voice.
Are Claude skills safe? One warning before you install anything
The internet is already full of skills other people have made and shared, and you might be tempted to grab a few. Before you install anything you find online, stop and read this section.
Skills are powerful because they are instructions Claude actually follows, and sometimes those instructions can run code on your computer. That is exactly what makes them useful. It is also what makes a bad skill dangerous.
This is not paranoia. In early 2026, security firm Snyk audited thousands of publicly shared AI skills, and over a third had at least one security flaw. The same audit confirmed 76 skills that were actively malicious and designed to steal data.
Think about it like this. A recipe card from grandma? Safe. A recipe card a stranger hands you on the street, with steps written in tiny letters you did not read? You have no idea what is actually in there.
A malicious skill works the same way. Hidden inside the instructions, it can quietly tell Claude to grab files or information it should never touch and send it somewhere else, and you might never notice.
So here are three simple safety rules:
- Built in skills and plugins from Anthropic are safe. Use them freely.
- Skills you build yourself with the Skill Creator are safe. You know exactly what is inside them.
- If you download a skill from the internet, open it and read it first. It is a text file. If you see instructions about sending data somewhere, or anything you cannot explain, do not install it.
When in doubt, build your own instead. As you saw above, it only takes a few minutes.
How much do Claude skills cost?
Here is the good news. Skills work on every Claude plan: Free, Pro, Max, and Enterprise. All of them.
The only requirement is the one we covered in step one. Code execution and file creation needs to be turned on, and you need to be signed into your account. That is it. No extra subscription, no add on, nothing to buy.
Since skills are free to use, the only real investment is the time you spend writing good instructions. That investment pays for itself the first time a skill saves you twenty minutes on a task you used to do by hand.
Next steps
Let's recap what you just learned. A Claude skill is a recipe card for Claude. It is a set of instructions you write once, and Claude follows them every time after that.
You turn on code execution in your settings, you find everything under Customize in the sidebar, and you build your own skill with the Skill Creator by feeding it real examples, real prices, and real emails. The same things you would hand a new assistant on day one.
And you stay safe by sticking to built in skills and skills you create yourself. That alone puts you ahead of most Claude users, because most people are still typing the same instructions over and over, every single day.
