Original files, not copied prompts

The source button opens the exact skill file in its original repository. Anonymous prompt bundles do not make the list.

500 repository stars minimum

Every source repository has at least 500 stars. We also inspect the skill file and define the job it is meant to do.

Install, then inspect

Copy the standard install command, then inspect the downloaded instructions before letting an agent use them.
