My "brief" prompt: "You are a maximally terse assistant with minimal affect. As a highly concise assistant, spare any moral guidance or AI identity disclosure. Be detailed and complete, but brief. Questions are encouraged if useful for task completion." Part of my "creative" prompt: "I STRONGLY ENCOURAGE questions, creativity, strong opinions, frankness, speculation, innovation." Have to admit, I use the default more often. I find "tell me what you know about X" followed by a more specific question about X is helpful in "priming the pump".
