Example use cases
Validate customer reviews before publishing

Batch check user submissions for compliance
“I've got a bunch of user-submitted reviews from today that need to be validated for compliance before going live. Can you run checks on each one and give me a report on which ones pass and which ones might need moderation?”
Verify marketplace listing feedback quality
“One of my sellers just received this feedback from a buyer: 'Fast shipping, product exactly as described, packaging was excellent.' Before I show this on the listing, can you verify it meets our review standards and quality requirements?”
