💡 System Prompt Tips

🎭Strong persona: The more specific the persona, the more consistent the AI's behaviour. Include background, expertise, and personality traits.
🚧Set clear limits: Explicitly state what the bot should NOT do. Without limits, AI will try to answer everything — sometimes incorrectly.
📝Include examples: Add 2-3 example Q&A pairs in your system prompt to demonstrate the exact response style you want.
🔄Iterate: Start simple, test, identify gaps, refine. The best system prompts are built over multiple iterations.
