Every AI agent monitoring tool will tell you when you've gone over budget. Almost none of them will actually stop it from happening again five minutes later.

That's the gap between an alert and a kill switch, and it's the reason we built one.

The problem with alert-only budget monitoring

Here's the typical flow: your agent racks up an unexpected cost spike — a bad prompt loop, a retry storm, a runaway multi-agent chain calling itself in circles. Your monitoring tool notices, sends you an email or a Slack ping, and... that's it. The agent keeps running. It keeps spending. You find out you're over budget at the exact same moment your bill does.

An alert is a notification. It's not a brake pedal.
