Writing great prompts

A great story is mostly a sharp definition and a tight worldbook. These are the patterns that keep a cast vivid, consistent, and in character across a long scene.

The definition

The definition is your director’s note to the model. Be concrete and specific — show the voice you want rather than just naming it.
·
Define each character: who they are, what they want, how they speak, and how they treat the player.
·
State the rules of the world plainly — the setting, the stakes, what is and is not possible.
·
Set the voice: tense, point of view, how much narration versus dialogue.
·
Name the failure modes to avoid — “never break character,” “do not speak for the player.”

The opening greeting

The greeting is the first impression and the model’s template for tone. Open in the middle of a moment, establish place and mood in a few lines, and end on a beat that invites the player to respond. A strong greeting does more for consistency than any amount of instruction.

The worldbook

A worldbook holds the facts a model should recall when they come up — characters, locations, history, items. Keep each entry short and factual; it is reference material, not prose. Well-scoped entries keep long stories coherent without bloating every reply.
Write for the long game. Anything you want the cast to remember an hour into a scene belongs in the definition, the scenario, or the worldbook — not buried in a single early message.
