Iterative Prompting
Refining a prompt through multiple rounds of feedback until the output meets requirements.
Full Definition
Iterative prompting treats prompt writing as a loop rather than a one-shot event. You send an initial prompt, evaluate the output, identify what is wrong or missing, then revise the prompt and repeat. Each iteration narrows the gap between model output and desired output. Good iterative practice involves changing only one variable per iteration so you can isolate what caused an improvement. This process is the practical day-to-day workflow of prompt engineering and is how most production prompts are actually developed — not through inspiration but through systematic refinement.
Examples
First draft asks for a product description; second iteration adds 'under 50 words, focus on benefits not features'; third adds a specific tone requirement.
Testing five variants of a classification prompt on a 20-example eval set and keeping the version with the highest accuracy.
