commercetools AI Hub product feeds

AI Hub feeds go to several vendors: OpenAI Commerce feed (ChatGPT shopping), OpenAI Ads feed, Google Merchant Center and Microsoft Merchant Center. "AI Hub" names the whole export, not one vendor.

Exports what commercetools has for a product selection, per vendor, as a semi-finished working file: every row, every vendor field, blanks where commercetools has no value, and a note per row listing the required fields it is missing. The business team completes the file offline; the completed file comes back and is converted, unchanged, into the vendor upload format. The merchant decides what and when to upload; the skill supplies facts and guidance.
