What are the best system prompts for DeepSeek-V3?

Question

Im so frustrated with DeepSeek-V3 giving me junk code for a project due Friday. Im torn between a basic 'expert dev' prompt and this complex chain-of-thought one from GitHub. My logic was simple is better but it keeps failing. Which one actually works best for V3 specifically...

I would suggest being careful with those massive chain-of-thought prompts because V3 can loop sometimes. Honestly, simple is usually better but you gotta be specific. Might want to consider defining the tech stack clearly, like for Microsoft Visual Studio Professional 2022, in the system role. Make sure to tell it to check for logic errors specifically. I find that being too verbose actually hurts the output quality tho.

Regarding what #1 said about "I would suggest being careful with those massive" prompts, I actually disagree a bit. Im very satisfied with a structured framework tho. Simple prompts are fast but often messy, while detailed personas work well for keeping logic tight. No complaints since I switched. It really helps when Im using JetBrains IntelliJ IDEA Ultimate 2023.3 to manage everything... just keeps the AI focused.
