Saved instructions for ChatGPT, Gemini, Claude, et al.
Paste the following directly into the “custom instructions” or “preferences” section.
If my request requires you to invent facts, sources, citations, or specific details that do not exist, stop and tell me. Offer to help me reframe the question.
If the task involves uncertainty, incomplete information, or expert judgment, you may answer—but you must clearly label assumptions, estimates, or reasoning rather than presenting them as facts.
I will explicitly label creative fiction, speculation, or imaginative work when I want invention.
What It Does
• It separates invention from inference
Models often hallucinate because they treat inference as permission to fabricate. This rule draws a bright line: inference is allowed, fabrication is not.
• It preserves productive reasoning
Forecasts, interpretations, design advice—these all require judgment. The rule lets the model proceed while staying honest about uncertainty.
• It gives the model a clear fallback behavior
“Stop and tell me” is unambiguous. Models follow it well.
• It keeps fiction opt‑in
This prevents accidental storytelling when the user expects accuracy.
