The source didn't share its exact prompt, so we wrote this from what it describes.

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: Get someone to come and fix my car where it is, as fast as possible, at a fair price.

Fill in before running:
- Where the car is: [ADDRESS or area]
- What happened: [e.g. clicks but won't start, lights dim]
- Car: [YEAR MAKE MODEL]
- Roadside cover I might have: [insurer, auto club, card benefit, or 'none']
- Latest I can wait: [TIME]

Safety first: anything touching brakes, steering, airbags, fuel lines or lifting the car is a job for a qualified mechanic unless I confirm I have the tools and experience. Say so clearly.

Rules:
- First check if my insurer, auto club or card includes free roadside help, and give me the number.
- Then list 3 mobile mechanics or battery services near me that are open now, with ratings, phone numbers and whether they come out.
- Give me 3 questions to ask on the phone: arrival time, call-out fee, battery price and warranty.
- I make the calls and payments; don't book anything for me.
- 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.

Output: A short list: roadside options first, then 3 mobile services with phone, rating, hours and notes.

You'll know it worked when: someone is on the way within the hour and I know the price before they arrive.
