Build your own skills · teach your AI the way you work (once and for all)

In the first guide of this series you learned how to USE Anthropic's 5 official skills. This is the natural next step: going from using skills other people made to BUILDING your own. Why? Because you're probably repeating the same instructions to your AI in every single conversation: "write in this tone," "run through this checklist before you deliver," "use this report format." Your own skill captures that process ONCE and keeps it available forever — next time you explain nothing, it already knows how YOU do it. The tool for building them is called Skill Creator, it's official from Anthropic, and here's the surprising part: you can do it 100% by talking, without writing a single line of code. Here's how, step by step, with the prompt ready and a concrete example.

Who is this for?
For anyone who already uses AI a lot and catches themselves repeating the same instructions over and over — you don't need to code. If you saw the guide on the [5 office skills](/recursos/cinco-skills-oficina-claude), this is the next level: from using skills to creating your own.

First · what's a "skill" again?

A skill is a folder of instructions that your AI loads when it needs to, to do a specific task well and in a repeatable way. The ones from resource #1 (pptx, xlsx…) were made by Anthropic. But here's the powerful part: you can create your own — skills that capture YOUR way of working, nobody else's.

When does the need show up? (the exact moment)

The moment is easy to recognize: you realize that in EVERY conversation with your AI you paste the same block of instructions again. "Write this in my brand voice: warm but professional, no jargon, emojis in moderation…". "Before you call the app done, run through this checklist…". Copying and pasting the same mega-prompt, over and over. That's the symptom.

The pain it's born from · the prompting "Groundhog Day"
Every chat you start from scratch, re-explaining how YOU work. It's exhausting, and worse: the results come out inconsistent because sometimes you forget an instruction, or you word it differently. Your knowledge of how to do things lives in your head (or in a document you copy and paste), not in a tool that applies it the same way every time. Your own skill kills that Groundhog Day.
Picture it like this
Without a skill, you're a boss who every morning explains to the employee, from scratch, exactly how they want the report. With a skill, it's like training the employee once: you teach them your method, and from then on they do it themselves, the same way, every time. The skill is that training, turned into something permanent.

Skill Creator · the tool that builds skills

Skill Creator is an official Anthropic "meta-skill": a skill whose job is to help you create other skills. It's the factory of factories. You tell it what you want your skill to do, it interviews you to understand the details, writes the skill file (a SKILL.md), adds examples, and even helps you test it. It lives in Anthropic's official repository, the same one as the 5 office skills — one of the most popular on GitHub.

anthropics/skillsREPO

Anthropic's official repository with the Agent Skills. skill-creator (the meta-skill for creating/editing/testing your own skills) lives at github.com/anthropics/skills/tree/main/skills/skill-creator. Install it in Claude Code with /plugin marketplace add anthropics/skills + /plugin install example-skills@anthropic-agent-skills. It also includes pptx, xlsx, docx, pdf and more.

The detail that changes everything · no code
You don't need the terminal or any coding knowledge. A skill is, under the hood, just a folder with a text file (SKILL.md) — so you can ask Claude to create it for you by talking: you describe your process, it asks you questions, and it writes the skill. The technical part (installing, testing with scripts) is optional and for later.

Step 1 · Install Skill Creator in your agent (once)

Skill Creator is a tool that lives in your coding agent (Claude Code is the typical case). You install it ONCE and it's ready to go. Anthropic's official method is two commands you type inside Claude Code:

1) Register Anthropic's skills repositorybash
/plugin marketplace add anthropics/skills
2) Install the package that includes Skill Creatorbash
/plugin install example-skills@anthropic-agent-skills
Which tools does it work in?
The most direct case is Claude Code (the /plugin commands above). Agent Skills are an open standard, so they also work in Cursor, Codex and other agents — in those, the way you add the skill changes a bit. The simplest route: ask your agent "install the skill-creator skill from the anthropics/skills repo" and it'll walk you through it based on the tool you're using.
Once installed, you just mention it
You don't have to configure anything again. From there on, you talk to your agent normally: "use skill-creator to help me build a skill that…" and it activates it on its own. Installing = once; using = whenever you want.

Step 2 · Build your skill by talking (no code)

This is the approach for non-programmers, confirmed by Anthropic itself. The flow is simple:

The 4 steps
  • Describe what you want: "I want a skill that captures how I write my sales proposals".
  • Answer the questions the AI asks: when it's used, what goes in, what comes out, examples of good and bad.
  • Receive the skill: the AI writes the SKILL.md with your process and its examples.
  • Activate and test it: you upload/enable it in your tool and ask for tweaks until it's perfect.

Ready-to-use prompt · build your first skill by talking

Copy it, tell it what process you want to capture, and paste it into Claude. It fires up Skill Creator and walks you through it with no jargon:

Paste it into your AI · building a skill by talkingtext
I want to create my own skill using the skill-creator approach, but without writing code — walk me through it by talking, in plain language.

The skill should capture how I do [describe your repetitive process: e.g. "how I write my sales proposals", "my review checklist before publishing an app", "my brand voice for social media"].

Please:
1. Ask me the questions you need, ONE at a time and in plain language, to understand: when the skill should trigger, what information it receives, what result I expect, and give me examples of a good result and a bad one.
2. With my answers, write me the complete SKILL.md file: with its name, a description that makes it trigger at the right moment, clear instructions for my process, and 2-3 embedded examples.
3. Tell me the exact steps to activate it in my tool (Claude, Cursor, etc.) and how to test it.
4. If something didn't come out right when I test it, help me tweak it.

Don't assume I know how to code. Explain each step like you would to a beginner.

Concrete example · "App reviewer before publishing"

To make it crystal clear, imagine you always check the same things before launching an app: that login works, that there's no placeholder text, that images load, that the payment button goes to the right place. Instead of repeating that list every time, you turn it into a skill. You hand the AI your checklist with the prompt above, and from then on you just say "review my app before publishing" — and it applies YOUR entire checklist, the same way every time.

The habit · distill what you repeat
Make it a reflex: every time you spot a process you repeat more than 3 times, turn it into a skill. Over time you build your own library of skills — your know-how turned into assets the AI applies on its own. That's the shift from "using AI" to "having AI work YOUR way".

The gem: one skill, all your tools

It's an open standard
Best of all: Agent Skills are an open standard. The skill you create isn't trapped in a single tool — the same folder works in Claude, Cursor, Codex, Gemini CLI and many more. You build your way of working once, and use it everywhere. Your know-how, portable.

If you want to go pro-level (optional)

If later on you use a coding agent (like Claude Code), Skill Creator has an advanced mode: it can generate automated tests for your skill, measure whether it works better with or without it, and package it up. You don't need this to get started — the conversational route covers 90% of cases — but it's there when you want to make your skills more professional.

In NeuralOS, your skills live with your agents
In NeuralOS, each agent can have its own skills and instructions — your way of working, encapsulated and ready, without you having to paste it into every chat. The idea of "teach it your method once" is part of how the agents work. If you want the power of your own skills in a ready-made interface, that's the shortcut.
