Let’s explain to you how to create your own Claude Skilland thus have a personalized version of the artificial intelligence from Anthropic. The Claude’s Skills They are a series of instructions that you can upload to a chat so you don’t have to repeat them every time you want to give a specific compliment.
Let’s start the article by reviewing what exactly the skills of Claude. And then, we are going to tell you step by step how to create a skill in the simplest way possible.
What exactly are Claude’s Skills?
Skills or abilities are a system with which you can create Claude customizations. With them, you can add a command layer to the generic versionand thus be able to use a version of the AI adapted to what you want.
A skill is an encapsulated procedurethe way to tell Claude how to perform specific tasks, under what conditions and with what rules you want him to do it, without having to repeat these instructions in every conversation.
Imagine that you use Claude to repeatedly do specific tasks. Every time you want to do one of these tasks in a new chat you will have to describe what you want, something that can be tedious, especially when the instructions are longer and more complex.
Skills allow you to encapsulate these instructions, so that when you activate one, these instructions are implicit in what you ask of it. When you write the prompt, Claude will first read the ability and take into account what you ask of him there.
For example, imagine that you like to analyze the SEO of something you write about. So, every time you go to ask for this analysis you have to give the instructions to Claude, but If you load a Skill you do not need to give the instructionsand you can simply activate it and write the text you want to analyze.
How to create your own Skills


To create your own Claude skill, you need to open the AI and click on the section Personalize that you have in the left column. Remember that Skills are a paid function.


When you click on Personalizeyou will access two different options. On this screen, you must click on the option Skills that will appear next to the connectors.


You will enter the Skills page, where by default you will see several examples of those created within Claude himself. Here, click on the + button above, and in the menu that opens choose the option Write the instructions for the skill to create one in the simplest way.


This will take you to the screen where you will have to fill out the three fields necessary to create your Skill. You will have to give it a name, instructions and a knowledge base in the event that the latter is necessary.
Three fields to define your new Skill
The first thing you have to do is give your skill a name. This is the distinctive name it will have, and with which it will appear in your list of created Gems. It is recommended that it be a clear and distinctive name. The name will appear as if it were a file, with hyphens instead of spaces and in lower case.
Then you will have to specify description. It’s a short description that will appear overlaid when you mouse over it in the skills list. Therefore, you have to write a short summary of what you do.
Claude will look at your skills in each prompt you write, to use it in case he detects that you have referred to one of them with the task you have asked of him. That is why it is important to have useful and direct information in the name and descriptionso that both the AI and you can distinguish what each one is for.
Then comes the most complex part, because you will have to write detailed instructions of skill. This is the most important step, because it serves to define the role, tone and rules that this automation must follow. You have to specify everything you can when you are going to write these instructions.
These are some of the most important aspects to include in the instructions when you go to create your Skill:
- Personality: You will have to say what their role is, the character they should play and the tone they should use. For example, you can ask them to act like a rigorous but friendly college professor, or a light-hearted, Reels-focused content writer. Whatever you want, but this personality is important to define to establish behavior.
- Objective and rules: It is also equally important to specify what the main task of the Gem is, and what rules to use. For example, you can say, “Your job is to review the texts to find spelling and grammar errors and improve the structure,” for example. You can also say things like “Never talk about topics other than…” to make him focus on that specific task.
- Format: This is optional, but you will also be able to define the structure of the answers. For example, you can ask that I always start with a summary and then list in several points, or whatever you think is necessary. In the end, the point is to define a response structure that is useful and in line with the tasks you want this Gemini customization to perform.
If you don’t clarify by writing the instructionsyou have the option of using Claude himself to help you write them. To do this, open the AI in another browser tab, and in a chat ask it to generate instructions for creating a Skill, adding a couple of instructions from which to start.


And that’s it. Once you have created a Skill, all you have to do is choose it from the menu from Claude’s new chat. You will have to press the + button, go to Skills, and choose yours. Once you have it selected, you just have to add the text you want, and Claude will process it according to the instructions of the skill you have loaded.
You can also make a request that mentions what a skill does that you have created, even if you do not select it. By doing so, Claude will analyze if what you have asked of him can be done with any of the skills, and then he will use it automatically.
