Definition
Instructions are where your evaluation logic lives. Write a clear, specific question or a statement for the model to judge, and state the exact condition rather than relying on implied intent. Jev answers the question you wrote, not the one you meant.
A string is enough for most questions. An object or array can hold the question in one field and the data it refers to in others, which keeps long context, examples, and values from your code out of a string template.
