The skill of writing inputs that get better outputs from AI. Less technical than it sounds — most of it is good writing habits.
Prompt engineering is the practice of writing the messages you send to an AI model so it produces useful, accurate, and well-formatted answers. There's no programming involved. The "engineering" part is just being deliberate about how you phrase things — like writing a clear brief instead of a vague one.
The same AI model can produce mediocre or excellent output depending entirely on how you ask. A vague prompt like "write a tweet about productivity" gets you a generic line. A specific prompt — with role, context, format, and constraints — gets you something you'd actually post.
Bad prompt: "Write a cover letter."
Engineered prompt: "Act as a hiring manager who has read 10,000 cover letters. Write a 200-word cover letter for a junior data analyst role at a mid-sized SaaS company. I'm transitioning from marketing analytics. Highlight SQL, A/B testing, and stakeholder communication. Tone: confident but warm. End with a soft call to chat."
Same task. Wildly different outputs. That's prompt engineering.
