I'm not much of a skills person. I mostly use them as shortcuts for prompts I don't want to write again, or spec sheets that don't change.
What I see coming is software delivery via prompt.
You need a piece of software. Someone gives you a premade prompt. You paste it into your agent, and it builds the thing for you. That becomes the way you get it, instead of downloading an installer.
And because the agent already has your preferences and context, your version comes out a little different from mine. You don't have to explain how you like everything every time.
Imagine sharing a prompt for a time tracker. One person gets keyboard controls and a compact list. Another gets large buttons and labels in their language. Both track time. The same description produces something that fits each person.
An early piece of this already exists: Lovable lets people share app-building prompts through links. The recipient submits the prompt to start building. Reliable personal adaptation is the next part of the prediction.
The software still needs to run somewhere, save your data, and survive updates. The agent would have to handle that work too.
I think "send me the prompt" will become a normal way to get software. The same prompt, with a slightly different flavor for each of us.
