What's an AI “skill”?
And how to use it for your store.
A plain-English guide, no tech background needed. If you can write a marketing brief, you can build a skill.
A skill is a set of instructions you teach an AI once, so it does one specific job the same great way every time. Think of it like a saved recipe or a team playbook your AI follows, instead of re-explaining what you want on every single task.
Prompt vs. skill: the difference
A single request. You ask the AI to do one thing, one time. Perfect for quick, one-off tasks.
A reusable playbook. You bundle your instructions and your brand info once, then reuse it forever. Perfect for tasks you do again and again.
Bottom line: a prompt is a one-off. A skill is a prompt you've saved and taught your brand to, so anyone on the team gets on-brand results without starting from scratch.
Why marketers love them
What goes inside a skill
Just four simple ingredients, and a good prompt from this library already gives you the first two:
- The job: what it does. (“write product descriptions”)
- The rules: how you want it done. (voice, length, format, do's & don'ts)
- Your context: brand voice, audience, product info. (added once)
- Examples: one or two “this is what great looks like” samples.
Turn a prompt into a skill in 4 steps
Product descriptions, weekly emails, ad copy, support replies, or anything you do more than once a week.
It's your starting instructions, already written by us. Don't start from a blank page.
Paste your brand voice, audience and product details into the instructions so you never re-type them again.
Now anyone pastes a new product (or brief) and gets on-brand output in seconds. Where to save it:
- In Claude: create a Project (or Skill) and paste your instructions + brand info as its knowledge.
- In ChatGPT: create a Custom GPT (or save the prompt) and paste the same.
Ecommerce skill ideas to steal
- Start from a library prompt, never from a blank page.
- Feed it your real brand voice and a couple of great examples. That's where the magic is.
- Keep one skill per job. A focused skill beats a do-everything one.
- Review the first few outputs and tweak the instructions. 10 minutes of tuning pays off forever.
