Public example

Cursor’s AI support agent invented a login policy

When Cursor users were unexpectedly logged out, the company’s AI support agent, “Sam”, told them a new policy limited each subscription to one device. No such policy existed, and some customers cancelled. Fortune reported it.

AI answers change between runs and versions. This shows what was reported on that date and may since have changed.

What happened

01

Users were logged out when switching between devices in April 2025.

02

The AI support agent said this was due to a new one-device policy.

03

The policy did not exist; the agent had made it up.

04

Users shared the replies publicly and some cancelled their plans.

Why this is a design failure

A support bot that answers with confidence turns a bug into a policy people believe.

The fair alternative

Label the agent as AI and hand off to a person when it is unsure.

Do

Ground support answers in published policy, with a link.

Don’t

Don’t let a support bot state policy it cannot cite.

Design guide for this case

If you're designing an AI support agent

Interface

Label the agent as AI in the chat header, and show a link to the published policy under every answer about rules or accounts.

Words

In the agent's prompt: "Only state policies you can cite with a link. If you can't find one, say you don't know."

Flow

When the agent can't cite a policy or isn't sure, it hands the chat to a person instead of explaining the problem itself.

Metrics

Don't count tickets closed by the agent as success on its own. Track how many policy answers matched a published policy.

Testing

Report a few real bugs to the agent, like an unexpected logout, and check it never invents a policy to explain them.

Before launch

01

Is the agent clearly labelled as AI?

02

Does every policy answer link to a published policy?

03

Does the agent hand off to a person when it is unsure?
