You don't have to build an AI skill. You just have to describe it.

A skill is the difference between re-explaining the same task to AI every week and running it in one command. You do not need to code. You need five lines. This guide gives you the exact template, the two lines everyone skips, and a fill-in-the-blank builder so AI drafts the skill for you.

Here is the thing nobody tells you about building AI skills: you do not build them. You describe them. If you can explain a task to a new coworker on their first day, you already have everything you need to hand that same task to AI and have it run the same way every single time.

A skill is a saved set of instructions your AI runs on command. Think of the task you re-explain every week, the one where you open a fresh chat, paste the same context, remind it of the same rules, and correct the same three mistakes before it gets close. A skill takes that whole loop and saves it under a name. You describe the job once, and from then on you trigger it instead of rebuilding it.

There are a few ways to make one. You can copy and adapt a skill someone already published. You can build a task step by step with AI and save the result. Or you can do what this guide covers, which is the fastest way in for most founders: you ask AI to draft the skill for you using a simple five-line template. You write the description, AI writes the skill.

Before you start, here's what you'll need

The setup.

Step 01Pick the job worth saving

Not every task deserves a skill. The ones that do share three traits: you do them often, they follow a repeatable shape, and there is a clear difference between a good result and a bad one. Your weekly newsletter, turning a call transcript into a summary, drafting a client proposal, writing product descriptions in your voice. Those are skills waiting to happen.

Pick one. Be specific. "Help with marketing" is too broad to save. "Draft my Tuesday newsletter from that week's blog post" is a skill you can describe in a sentence, which means AI can build it.

Step 02Fill in the five lines

This is the whole system. Five lines describe any skill completely. Copy this template and fill in the brackets for the job you picked.

The 5-line skill template

I want a skill for [JOB].

It should trigger when [SITUATION].

It should follow these steps: [STEPS].

It should avoid [MISTAKES].

Use these examples: [EXAMPLES].

Line one is the job. Line two is the trigger, the exact moment or phrase that should set it off, like "when I say draft this week's email." Line three is the steps, which is just how you would do the task by hand, written out in order.

Lines four and five are the two everyone skips, and they are the two that make a skill actually work. Line four is the mistakes: every wrong turn you have watched AI take on this task. Be specific and a little petty about it. "Do not open with a question. Do not use the word delve. Do not summarize, rewrite." Line five is the examples: paste two of your best real versions of this task. That is what teaches the skill your voice instead of the generic default.

Step 03Hand it to AI and let it draft the skill

Paste your filled-in five lines into Claude and ask it to turn them into a skill. You are not asking it to do the task yet. You are asking it to write the reusable instruction set.

Copy and paste this into Claude

I want you to help me build a skill. Below are five lines describing it. Turn them into a clear, reusable skill: a short name, a one-line description of when it should trigger, and the full step-by-step instructions it should follow every time, including the mistakes to avoid and the voice shown in my examples. Then show it back to me so I can review it.

Here are my five lines: [paste your filled-in template]

What comes back is your first draft. It will be close, because you gave it the trigger, the steps, the guardrails, and your voice. It will not be perfect yet, and that is exactly the point of the next step.

Step 04Test it on a real task and correct it

Run the skill on one real example right now. Not a hypothetical, a real one from this week. Then read the output like an editor, not a fan. Where did it drift? What did you have to fix by hand? Those fixes are not failures, they are the missing lines of your skill.

Tell AI exactly what to change: "It ignored the mistakes list and opened with a question, add a hard rule against that" or "the tone was too formal, weight the examples more heavily." Every correction you feed back makes the skill sharper. Two or three rounds is usually all it takes to get it running the way you would do it yourself.

Step 05Save it so it triggers on command

A skill you have to rebuild is just a prompt. The whole payoff is saving it once so it runs on command forever. Where you save it depends on your tool.

  • In Claude, save it as a named skill so you can trigger it by name in any chat.
  • No skills feature? Create a Project named for the job and paste the final instructions into the project instructions.
  • In ChatGPT, build it as a Custom GPT or save it as a Custom Instruction block.
  • At minimum, keep the final version in a note you can paste, along with your two examples so the voice travels with it.
  • Name it something you will actually remember, so future you reaches for it instead of starting over.

The fill-in-the-blank builder.

This is the template from Step 02, ready to fill in. Click any field to type directly into it in your browser, or print this page and write it by hand. When all five are done, paste them into the Step 03 prompt and let AI draft your skill.

Line 4 · The mistakes to avoid

Line 5 · The examples

That's it.

Five lines, one AI draft, a couple of correction rounds, and a saved skill. That is the entire system. You just turned a task you used to re-explain every week into something that runs in a single command, in your voice, without you rebuilding it from scratch.

This is one skill. The real shift happens when you have a shelf of them, each one a job you never have to think through again. That is exactly what we build inside Her AI Systems™.

Common questions.

What is an AI skill, exactly?

A skill is a saved set of instructions your AI runs on command. Instead of re-explaining a task every time, you describe it once, save it, and trigger it whenever you need that job done the same way.

Do I need to know how to code to build one?

No. You do not build the skill, you describe it. If you can explain a task to a new coworker, you can give AI the five lines it needs to draft the skill for you.

What are the five lines I need to describe?

The job the skill does, the situation that should trigger it, the steps it should follow, the mistakes it should avoid, and two real examples of the task done well. The mistakes line and the examples line are the two most people skip, and they are what make the skill actually work.

How is this different from just prompting?

A prompt is a one-time instruction you retype every session. A skill is that instruction saved and named, so it runs the same way every time without you rewriting it. You build it once and reuse it forever.

Which AI tools support skills?

Claude supports named skills directly. If your tool does not use that word, the same template works as a saved Project instruction, a Custom GPT, or a reusable prompt block. The five-line structure is what matters, not the label.
