Agent Allowances
When an AI agent spends money on your behalf, it usually does so with a password-like credential that can drain whatever account sits behind it, and if something goes wrong you have to notice, log in, and revoke that credential while the agent keeps spending in the meantime. There was no way to hand an autonomous agent a fixed amount of money it could use on its own, anywhere, while guaranteeing the owner could never lose more than that amount and could always take the rest back in a single action.
