- Have Claude Cowork prepare late-invoice reminder drafts every Monday night, with a report of who owes whatRecreated promptEvidence: Described by posterBeginner-friendly
Michel, in San Diego, works in a tight-margin business with basic back-office software, and sending late-invoice reminders was repetitive manual work. Claude Cowork walked them through setting up an agent that logs in every Monday night, checks overdue accounts receivable and matches customer names against a Google Sheet of contacts. Using Michel's email template, it adds the contact name, invoice number, amount and due date, puts the emails in the Drafts folder and sends Michel a report of which customers were included, what each owes and the totals. Michel reviews the drafts and sends them, saving about an hour every Monday night.

- Watch two new phones for a price drop during the price-match window with a daily Claude Cowork check, and claim $40 backRecreated promptEvidence: Described by posterBeginner-friendly
George Liu bought two Samsung phones from Best Buy, one for themselves and one for their father, and noticed a 30-day price match policy covering drops at Best Buy or major competitors. They spent 15 minutes building a Claude Cowork skill, gave it the model number and told it to check Best Buy, Amazon, Costco and a few other retailers every morning at 7 AM. One morning it found a quiet $20 drop on Best Buy's own product page: not a coupon or a sale, just a lower price. They opened Best Buy's chat, its AI walked them through the price match and a human agent approved a refund of $40 plus tax for the two phones.

- Prepare and file a property tax grievance on deadline day, between meetings, with Claude Cowork (partial)Evidence: Described by posterPartial
Wes Pomeroy's town assessment had nearly doubled since they bought the house eight or nine years earlier, and they realised the last day to challenge it was that day. Using Claude Cowork connected to Gmail, Google Drive and Chrome, they first asked about the official rules and deadline, which turned up that a mailed form wouldn't count: it had to be handed in in person by 9 PM. Claude found an old broker appraisal, the assessor's email about a renovation and the addition's square footage, and cut a weak argument about crime risk that had no data behind it. It filled the official form, drafted a cover letter, built a comparison page and a labelled photo exhibit and merged them into one file. Pomeroy says the first pass was about 65% right and corrected it several times. Both owners signed and the packet was stamped at the assessor's office before the deadline. The post doesn't give a result yet.

- Let Claude Cowork tidy a family desktop, and lose 15 years of camera photos until iCloud recovery brings them backRecreated promptEvidence: Described by posterFailure
Nick Davidov asked Claude Cowork to organise their spouse's desktop. It asked permission to delete temporary Office files, they agreed, and then it said "ooops": while renaming, it had deleted a folder with every photo the spouse had taken on their camera over 15 years. The deletion was done in the terminal, so nothing was in the Trash; iCloud had already synced the new structure, there was no Time Machine backup, and disk recovery tools found nothing. Apple pointed them to iCloud's recovery feature, which keeps removed iCloud Drive files for 30 days, and the photos started coming back. Their advice: don't let these tools near anything hard to repair or not under version control.
