Claude Duet's browser couldn't open FedEx tracking
Stephan asked Claude Duet to track a FedEx package and gave it the tracking number. Duet said its built-in browser was blocked from going to FedEx. He also couldn't upload zip files to it or have it join his private network, and says he wants to use it but it isn't there yet. Some big sites block automated browsers, so a quick task can fail for reasons that have nothing to do with how smart the agent is.
The lesson: Agent browsers get blocked by some big sites. For tracking, connect your email or use the carrier's alerts instead.
Copy this prompt
Track my package with [CARRIER] tracking number [NUMBER]. If you can't open the carrier's site, check my email for the carrier's or store's shipping updates instead and tell me the latest status and expected delivery date. Tell me which source you used.
Our own prompt, written from what the source describes. We haven't run it ourselves. Text in [BRACKETS] is what you replace.
Watch out for
- Sign up for text alerts on the carrier's site. They keep working when an agent can't get in.
