Method:

How we verify

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

Context: In a comparison test: from a head-to-head chatbot review, not a standalone agent test. Run by the parent on their own upcoming party.

Outcome

For their soon-to-be seven-year-old twins' party, Clifford Parker gave ChatGPT and Claude the same brief and budget over four rounds. Claude asked three questions first and produced a Minecraft sports day with a run sheet, prep list and budget tracker; ChatGPT found a local venue and entertainer with a phone number and booking script; ChatGPT's image generator won on invitations; and Claude, connected to Parker's computer, updated the RSVP spreadsheet from a phone message. It finished 2–2, with ChatGPT winning the tiebreaker.

Agent

ChatGPT, Claude

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

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Plan my child's birthday party from theme to RSVPs within budget.

What I can give you (ask for whatever's missing):
- Child's age, interests and number of guests
- Budget
- Date, area and whether I want home or a venue
- Anything to avoid (allergies, noise, mess)

Rules:
- Ask me up to three questions before planning.
- Give a run sheet, a prep list and a budget tracker.
- For venues or entertainers, give contact details and a short booking script, but don't contact anyone.
- Set up a simple RSVP tracker I can update by telling you who's coming.
- 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 party plan with theme, venue options, invitation text, run sheet, prep list, budget and RSVP tracker.

You'll know it worked when: the party is booked, invitations are out and I always know who's coming.

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