competence
The skill and understanding to do something well yourself, and to judge whether it has been done well by anyone, including a machine.
Competence is different from capability. Capability is what you can get done, with help. Competence is what you understand: the craft to do the thing, and the judgment to tell good work from poor work.
The two used to rise together, because to do something you had to learn it. With powerful tools they can come apart, so that a person can produce more than they can judge.
