The Claude “usage” UX is very bad. At the most basic level, there is no way to know what you’re actually paying for if you buy a “pro” plan or a “max” plan. Dario will take your $200 but he will give you a secret number of tokens in return.
I have no way of knowing what the numerator or denominator are for the usage progress bars. Plus they change them all the time. There’s no way to audit it. So if there was a malicious script siphoning usage it would be really hard to detect.
