Effective prompt engineering combines several techniques. You provide context about the task, the audience, and the desired format. You give examples of good and bad output so the model understands your standards. You set explicit constraints, like word count, tone, or what to exclude. You chain prompts together for complex tasks rather than trying to get everything in a single request. And you iterate: reviewing the output, identifying where it fell short, and refining your instructions. The best results come from treating prompts as a workflow, not a single input.
