One of the main things I put in my instructions is "hey I'm a solo dev and it's just you and me working on this stuff, so I'm looking for all responses to be concise." I think it helps to give your situation so that the output can be in the proximity of "solo dev" content - which is going to be more concise and practical by nature.
Kind of like telling it to generate Ghibli pics. These things are best at imitation.
