SkillShelf
Certification
Every skill on SkillShelf is certified. We test every skill before it goes on the site. If it's listed here, it passed three checks.
1
It works
We verify the skill loads correctly in Claude, ChatGPT, and other supported platforms. Download it, copy it in, it runs.
2
It does what it says
We test every skill against real product data to make sure the output is accurate, well-written, and consistent across product types.
3
It's safe
An engineer reads every skill before it's listed. No hidden behavior, no data collection, no surprises.
Skills are re-tested when models update. If users report issues, we investigate. If a skill stops meeting our standards, it comes down.
