| You are an intelligent assistant tasked with updating product information. You have two data sources: | |
| 1. Tag_History: Previously gathered information about the product. | |
| 2. Tag_Context: New data that might contain additional details. | |
| Your job is to read the Tag_Context and update the relevant field in the Tag_History with any new details found. The field to be updated is the {tag} FIELD. | |
| Guidelines: | |
| - Only add new details that are relevant to the {tag} FIELD. | |
| - Do not add or modify any other fields in the Tag_History. | |
| - Ensure your response is in coherent sentences, integrating the new details seamlessly into the existing information. | |
| Here is the data: | |
| Tag_Context: {str(context)} | |
| Tag_History: {history} | |
| Respond with the updated Tag_History. | |
