Have a desktop agent reserve an anniversary dinner

A poster used a desktop agent to make an anniversary booking at Serafina in San Francisco.

Done with Custom agent· Intermediate

What they did
They used Spongecake alongside OpenAI’s CUA to browse and fill out the reservation flow like a person would, rather than relying on a preset script. Their instructions included an OpenTable search link, a Friday-only constraint, the first available slot from 7:30 p.m. onward, their phone number, and instructions about marketing texts and reservation updates. They also flagged one-time passwords as a problem they still had to solve.
How it went
The agent got far enough for the poster to show it setting up the anniversary dinner at Serafina in San Francisco. The remaining weak point was OTP handling, which they said was not yet resolved.
Tips
Be specific about the restaurant, timing, and contact details so the agent does not waste time. If a step involves verification or final confirmation, make it pause and ask before continuing.

Use a desktop agent to look for and reserve a table at [restaurant name] in [city] for [number] people on [date] for [occasion]. Start from [OpenTable / Resy / the restaurant's booking page] and narrow the search to [day of week] with times no earlier than [time]. Enter my phone number as [phone number] and set these messaging preferences: [marketing opt-out / reservation updates allowed / other]. Before you submit the booking or accept any charge, deposit, or confirmation, stop and show me the reservation details for approval. If a verification code or one-time password appears, pause and wait for me to handle it.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
