What is prompt engineering?
Prompt engineering is the skill of writing inputs to AI models that reliably produce the output you actually want. It is not about tricks or hacks — it is about understanding how large language models process text and structuring your instructions to work with that understanding rather than against it.
Why it matters
The same task given to the same AI model produces dramatically different outputs depending on how the prompt is written. "Write a marketing email" and "Write a 150-word marketing email for a B2B SaaS tool aimed at operations managers, emphasising time savings, with a clear CTA to book a demo, in a professional but conversational tone" produce outputs that are not comparable in quality. Prompt engineering is the skill that closes that gap.
Core techniques
- Clear instruction. State exactly what you want, including format, length, tone, and audience.
- Context setting. Tell the model who it is, what it knows, and what constraints apply.
- Few-shot examples. Show the model 2–3 examples of the output format you want before asking for the real output.
- Chain-of-thought. Ask the model to think step by step before giving its final answer. Dramatically improves reasoning on complex problems.
- Output format specification. Request JSON, bullet points, tables, or specific structures to make outputs machine-readable or directly usable.
