How we verify

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

FailureThe source says the agent did not get the job done.

What went wrong: Looked up a same-named hotel in the wrong town, and the reply did not make that obvious.

Outcome

Asked to check a hotel's price with its town clearly stated, ChatGPT agent looked up a same-named hotel in another town, and the poster notes this wouldn't have been obvious from the reply.

Prompt Improved prompt

Strengthened by us to avoid the problem in the source. Not tested by the poster. It doesn't change what happened in the source.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Check the price of one specific hotel for my dates, and make sure it's the right hotel.

Check with me first: What's the hotel's name, town and address, and which dates?

What I'll give you:
- Hotel name ([HOTEL]), town ([TOWN]) and street address if I have it
- Check-in and check-out dates, guests and rooms

Rules:
- Before you check prices, confirm the hotel's town and address on its page match mine. Many hotels share a name.
- Start your reply with the full name and address of the hotel you found, so I can spot a mismatch.
- If more than one hotel matches the name, list them and ask me which one.
- Check the hotel's own site plus one booking site, for the same room type and dates.
- Don't book.

Output: The confirmed hotel name and address, the price from each source for my dates, room type, and links.

If anything here is unclear or missing, ask me instead of guessing.

You'll know it worked when: the address in the reply is the hotel I meant, with a price I can open and check.

Try this in:

ChatGPT Used in sourceGemini Grok

This prompt has blanks to fill in, like [HOTEL]. We'll copy it instead of filling it in, so you can edit it before you send.

Opens in a new tab. We don't see what you send.

These links are only a shortcut. We're not affiliated with OpenAI, Google or xAI, and your results may not match the source.

The prompt they actually used (our rebuild)

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

Check the price of this hotel in this town.
Optional stronger version

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

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Check the price of one specific hotel for my dates and prove it's the right hotel.

Quick check first: tell me if anything below is missing or unclear.

Inputs (fill in or confirm):
- Hotel name, town and address
- Dates, guests, rooms
- Booking site I prefer

Rules:
- Confirm the hotel by address and map pin before checking prices.
- State the town and address in the first line of your answer.
- Check the hotel's own site and one booking site.
- Include taxes and fees.
- Show room type, cancellation terms and whether breakfast is included.
- Give the price per night and the total for the stay.
- If two hotels share the name, list both and ask which one I mean.
- Note the date and time you checked prices.

What went wrong before, and how to avoid it:
- Last time it checked a same-named hotel in the wrong town: verify address first and show it.

If you get stuck: If several hotels share the name, list them and ask which one. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Match the address on the booking page to mine.

Output: Hotel confirmation line, then prices.

Done when: the price is for the right hotel.
