How the agent did it
- Prompted Codex to search for two seven-seat rental cars for Maine.
- Configured Codex to queue CAPTCHAs for the traveler to solve.
- Assigned a sub-agent to research rental-deal approaches on Reddit.
A traveler needed two rental cars for a trip to Maine, each capable of carrying seven people. They had access to several memberships and travel services, including Avis, Hertz, Costco and Chase Reserve Travel, and described the combinations of searches as too time-consuming to investigate manually.
The traveler used Codex with direct browser access to search for options. They instructed it to queue CAPTCHAs for them to solve, keeping those interruptions with the human. They also set up a sub-agent to search Reddit for other people's approaches to finding rental-car deals.
According to the post, the search found a third-party Avis reseller offering a discount code. The author gives a $600 price versus $1,100 for the cheapest direct Avis option and describes the total saving for both cars as $1,000. The wording around the quoted price and both cars is ambiguous, so the excerpt does not establish a precise booking total. The author says writing a decent prompt took 20 minutes; no completed booking is described. Who it's for: travelers comparing complex rental options across memberships and discount sources.
