PROMPT ENGINEERING
WHAT MAKES A GREAT PROMPT?
🎯
Specific Outcome
Instead of "write an email" say "write a cold email to a startup founder that gets a reply." The AI needs to know what success looks like.
👤
Define Your Audience
Who is reading or using the output? A technical engineer and a non-technical manager need completely different explanations of the same concept.
📏
Set Constraints
Give length, format, and tone instructions. "Under 150 words, professional but warm, no jargon" gives the AI a much clearer target.
🧩
Give Context
What's the situation? What have you already tried? What's the goal beyond this task? More context produces dramatically better outputs.
