Grounding Techniques You Build Into the Prompt

Apply fact-checking and validation techniques

SUBy Solomon UdohReviewed by Solomon UdohAI-assisted · human-reviewed
In short
Prompt-level grounding builds verification into the prompt before generation happens, using three techniques: explicitly permitting an "I don't know" response, restricting the answer to only the supplied source material, and requiring a specific checkable citation behind each claim. These are applied at prompt-writing time, before the output exists, and prevent hallucinations at the source rather than catching them afterward.
