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

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.

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.

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:

/plugin marketplace add anthropics/skills

/plugin install example-skills@anthropic-agent-skills

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

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

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:

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 gem: one skill, all your tools

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.
