The brief AI never forgets.

You have probably re-explained the same task to AI more times than you can count. Same instructions, different conversation, same frustration. There is a better way.

Last time I shared two prompts to get more from AI. Today we go deeper. Because before you can use Skills well, you need to understand what they actually are.

So, what is a Skill?

A Skill is a documented, reusable set of instructions that tells AI exactly how you would complete a task, every single time. Not just what to do, but how to do it. The steps, the context, the quality checks, all in one place.

Prompt, Skill, Agent. What's the difference?

Confused? Don't worry, it took me a moment to get my head around this too.

A Prompt is like telling a colleague: "Put together something for the client workshop on leadership." You give a topic, but not much more. Maybe it turns out great, maybe not. And next time, you explain it all over again from scratch.

A Skill is the brief that captures exactly how I design and run workshops. My methods, my quality checks, my structure, documented once and reusable whenever needed. The AI picks it up automatically when it detects I am working on a workshop.

An Agent is like having specialist contractors for different jobs. They come with their own experience, I brief them on my tools and context, and they get to work. But if something changes in how I work, I have to brief every single one of them individually.

Here is where Skills change that dynamic entirely.

Say you build several Agents and you want all of them to write in your tone of voice. Without Skills, you upload your guidelines into each Agent individually. Every time they evolve, you update every Agent one by one. With a Skill, you build it once, give each Agent access, and when you update it, every Agent pulls the latest version automatically. One update, everywhere, instantly.

You do not have to tell AI to use a Skill. The AI detects when a Skill is relevant and applies it automatically. No prompt needed. No re-explanation. It just knows.

I have a Skill I call my Content Accuracy Validator. Whenever I write something that includes a quote, a statistic, or a reference to someone else's work, it triggers automatically. It runs a rigorous validation process and gives me a list of flags, a confidence score, and suggested corrections. It is not a complex Skill. But it saves me from one of the most embarrassing things that can happen when you publish content: getting your facts wrong.

What goes inside a Skill?

A good Skill contains a clear trigger, step-by-step instructions, quality criteria, and any context AI needs to do it your way. Think of it as the brief that never needs rewriting. Just refining, as you get better at your craft.

How do you build one?

Start with this prompt: "What are the key decisions and rules I should define for a skill that [does this task]?"

Let AI walk you through the decisions. Make your choices. Approve the structure. And you have your first Skill.

The best place to start is a task you already do repeatedly. Workshop design, client onboarding, content creation, proposal writing. If you have done it more than a few times and it always looks roughly the same, it is a Skill waiting to be documented.

Not sure where to start? Ask AI directly: "This is what I do and how I work. What Skills would be most useful for me to build?" You might be surprised by what it suggests.

One thing worth keeping in mind

You will come across free Skills libraries. They can be a great source of inspiration, but I would caution against loading them into your AI chatbot without checking what is inside. Prompt injection is real: you do not always know what instructions have been embedded by their creator.

Til next time. Build it once, use it everywhere!
