Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Context: Retold in an interview post; the interviewee's own post names Grok.

Outcome

In an interview summary, a truck owner told he'd been quoted $930 at the dealership for spark plug replacement. Before approving it, he uploaded his warranty and maintenance PDFs, the estimate and a screenshot and asked AI, 'Is any of this already covered under my warranty?' It found the work was already included in his prepaid maintenance package, saving $930. The interviewee's own post names Grok as the tool.

Is any of this already covered under my warranty?
Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Check whether any work on a service estimate is already covered by my warranty or maintenance plan.

Fill in before running:
- Service estimate: [ATTACH]
- Warranty and maintenance plan documents: [ATTACH]
- Vehicle mileage: [NUMBER]

Rules:
- Match each line of the estimate to the plan terms, quoting the relevant clause.
- Mark each line covered, not covered or unclear.
- Draft a short polite question for the service advisor about covered items.
- Don't approve or decline work on my behalf.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.
- Ask the dealer to confirm coverage in writing before the work starts.

Output: A line-by-line coverage table and a message for the service advisor.

You'll know it worked when: I only approve work I actually need to pay for.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
