Directional Stimulus
A hint or nudge embedded in the prompt that steers the model toward a desired answer style.
Full Definition
Directional stimulus prompting injects a short cue — a keyword, partial sentence, or format hint — that biases the model's generation in a predictable direction without fully specifying the answer. Unlike hard constraints, directional stimuli work with the model's probability distribution rather than against it. They are particularly useful when you want creative latitude but need the response to land in a certain register or topic area. For example, beginning the assistant turn with 'Certainly! The three key risks are:' nudges the model to enumerate exactly three risks in an affirmative tone.
Examples
Ending the user turn with 'Answer in bullet points:' — the colon and format label steer the model to produce a bulleted list.
Starting the model's reply with 'The simplest explanation is' to push the output toward plain-language summaries.
