I realized most of my own prompts were pretty lazy. I usually just type "You are a coding expert" and hope for the best, which fails for complex tasks.
So, I built a Gemini Gem to automate the "Deep Research" side of prompt engineering. You give it a lazy/vague idea. This gem then acts as a Meta-Prompter to generate a production-ready System Prompt for you to use.
I am finding that doing this "pre-optimization" step drastically reduces hallucinations compared to raw zero-shot prompting.
Thought folks here might find it useful! Feedback welcome.
