Muse agent handles a rental car claim over several days, with one near-miss

A user had the Muse agent resolve a rental car claim across the rental, insurance and credit card companies over several days; it once tried to file on the wrong site, nearly exposing card details, and the user says Gemini 4 Argon's caution suits real work.

I tested Muse the other day. First of all: Kudos to the Muse team 🎉 I am so impressed with it! I’m sure lots of hard work went into it. The task I had for it was: “Resolve my rental car incident claim with: the rental, the car insurance, and the credit card companies.” Gotta have skin in the game to really test something 😁 The agent did amazing work over several days, emailing/cc-ing all the companies involved, collecting paperwork and filing claims over many websites. The one mistake the agent did commit - it tried to file the claim with the credit card company on the wrong website. If I didn’t catch that, my card details and personal data would go to this random website. And this was not prompt injection, it just didn’t double check my card indeed used a different claims website. This is a model issue, not infra or product. Some people say Gemini 4 Argon is too careful…for real-life work that touches critical data, I would rather have” too careful” over careless 🤷‍♂️ Happy that us (Google) is not behind in this, our Gemini Spark updated my car registration for me 2 months ago - no need to struggle through the DMV website anymore for this guy 😎
