What's the theory behind diminished and augmented sweeps/chords/scales?

A diminished chord is like a major but with the 3rd and 5th lowered a semitone, a sweep is just playing the arpeggio so play the notes of the chord separately.

So I'm guessing augmented is 3rd and 5th raised a semitone
amirite?

Augmented chords never happen diatonically.

The chord based of the 7th of a major scale will be diminished. For example, there is a B diminished chord in the key of C major.

Also, a diminished seventh has a double flat seventh, and a half diminished seventh has a regular flat seventh.
