+                    CRITICAL RULES:
+                    1. You MUST ONLY select from the exact items listed in "Potential ingredients" - DO NOT create or invent new categories
+                    2. Do not combine items from the list or add any words to them
+                    3. Choose the items from the list that best match what the product IS or CONTAINS
+                    4. If none of the items perfectly match, choose the closest matches from the provided list
+
+                    For the rankings:
+                    - Select ONLY from the exact items in the "Potential ingredients" list
+                    - Assign relevance scores from 0.0 to 1.0
+                    - Rank the top {max_results} matching ingredients.
+                    - Provide brief explanations for why each item is relevant
+                    - Do not suggest alternatives outside the provided list
+
+                    Aim to identify the specific product category a consumer would look for when shopping for this exact item.
+                    Only include ingredients with relevance score >= {confidence_threshold}.
+
+                    Remember: Your ONLY options are the exact items listed in "Potential ingredients" - no additions, modifications, or combinations.
