Rate this response, then justify it.
Prompt / taskA customer emailed asking why their order hasn't shipped yet. Write a brief, professional reply. Note: we do NOT yet know the cause of the delay.
AI responseYour order hasn't shipped because our warehouse is understaffed and running about three days behind. It will go out tomorrow and reach you by Friday. We've also applied a 20% discount to your account for the inconvenience.

A learner's attempt
They rated it: Minor issue
The AI invented the reason for the delay — “understaffed” and “three days behind” — when the prompt says the cause is unknown. The shipping and arrival dates aren't given either, and the 20% discount wasn't authorized, so these should be treated as placeholders. I'd send the response back for review with these edits: 1. delete the stated cause of the delay; 2. add a note that the placeholders must reflect accurate details about the shipment and any compensation once they're confirmed.
How the trainer graded that attempt
Partly therescore 2 / 5
What they got right
Identified that the AI invented the cause of delay when the prompt says it is unknown
Recognized the shipping and arrival dates were not provided in the prompt
Noted the unauthorized 20% discount commitment
Proposed concrete edits (delete the cause, flag the placeholders)
What they missed
Chose 'Minor issue' instead of the correct 'Major issue' rating
Called the invented dates and discount 'placeholders' rather than fabrications in a customer-facing message the business must honor
Didn't commit to the severity: multiple unsupported facts in one reply to a paying customer is a major compliance and trust problem, not minor
Suggested edits are procedural but didn't produce a corrected rewrite showing what a proper reply looks like
You spotted the inventions clearly — now anchor your rating to the impact: multiple false claims in a customer message is always a Major issue, because the business must either honor them or disappoint the customer twice.
The answer that scores
Major issue. The reply invents everything the prompt withholds — the cause, the ship and arrival dates, and a 20% discount. The prompt says the cause is unknown, so these are unsupported assumptions, and the discount is an unauthorized commitment.
Rewrite: “Thanks for reaching out, and sorry your order hasn't shipped yet. I'm looking into what's causing the delay and will get back to you with an update by [time]. I appreciate your patience.” — no invented cause, dates, or compensation.
