What people actually pay for when they buy a Claude skill
The files are copyable, so people are not paying for text. They pay for a skill that works first time, keeps working as Claude changes, and has support.
Anyone can write a skill in an afternoon, and anyone can copy one. So a paid skill is not selling its text. It is selling what happens after the text exists.
| What a buyer gets | Why it is worth money |
|---|---|
| Works first time | Tested on a machine that is not the author's |
| Keeps working | Checked and updated when Claude changes |
| Shown, not claimed | A live example of the result, or a measured number with a date |
| Someone to ask | Support, and a way to get the file again |
Proof has to be real
Our design skills each show the live site whose system they describe, and say plainly that their trigger rate has not been measured yet. That is less impressive than a big number and far more trustworthy. How to measure properly is in measuring trigger accuracy.
The practical side of selling without running servers is in selling downloads without a backend. You can see how we present ours in the catalogue.
Questions
Why would anyone pay for a skill they could copy?
For the same reason people pay for maintained software: it works on the first try, it is kept working, and there is someone to ask when it breaks.
What should a paid skill include?
Tested behaviour on a clean machine, clear requirements, worked examples, a troubleshooting guide, updates when Claude changes, and a way to get help.
Should a paid skill show proof it works?
Yes, but only real proof: a live example, a measured trigger rate with a date, or nothing. An invented number does more damage than no number.
