A developer encountered an unexpected hallucination in an AI sales chatbot where the bot listed products (suits) that the store did not carry. The root cause was not a flaw in the chatbot's architecture or search router, but rather how the system prompt injected the store's marketing description. The AI interpreted the marketing copy, which mentioned "suits," as an actual product category, leading to the inaccurate inventory suggestion. The issue was resolved by renaming the variable label from "Store:" to "About the store (brand voice / background — NOT a product catalog):" and adding a rule to prevent the model from treating descriptive text as a product catalog.
