The notification at 90 %
One a day, when Claude’s day reaches 90 % of its budget.
When today’s Claude use first reaches 90 % of the daily budget, Watchdogo shows one macOS notification. For Codex the number turns yellow too, without a notification. It does not repeat that day, even if you restart the app.
The first time, macOS asks whether Watchdogo may send notifications. If you said no, allow it in System Settings → Notifications → Watchdogo.
