Must be to a prompt, not an iterative process or a conversation. 

Must be consistent, as in, reusing the prompt also works at least 10%  (bare minimum) of the time. I will not even consider anything less consistent. 

As long as it can generate the English Alphabet keys in the correct order, I will consider it. If the A-Z is correct but the shift key and the caps lock key are swapped, that is counted as well.

For reference, i am refering to this layout:

The prompt must not tell the model the correct layout.
