Prompt Contradiction

A type of large language model failure in which the system disregards explicit instructions or constraints given in the user prompt, producing output that contradicts what was asked. For example, an AI responding with visual instructions like "click the green button" after the user has explicitly stated they are blind and using a screen reader. Prompt contradictions increase verification burden and erode trust in GenAI tools, and are a notable barrier for blind users seeking accessible, keyboard-only guidance.
