[BUG] Command /usage does not recognize subscription

What's Wrong?

When I use the /usage command, it returns "/usage is only available for subscription plans."

I am on a subscription plan. Claude Code does seem to recognize this, as when I use the /cost command, it returns "You are currently using your subscription to power your Claude Code usage".

It appears that /cost is detecting my Claude Pro subscription, but /usage is not.

What Should Happen?

The /usage command should return my token usage as a subscription user. If /usage is only intended for API users, the error message should be changed to reflect that.

Steps to Reproduce

4. Enter /usage

Additional Information

My usage is not visible on https://platform.claude.com/usage as that page appears to be stuck loading. There is a possibility that Claude is not properly capturing my token usage, contributing to the issue.
