Claude Usage Monitor 제작자: Aleš Kancilija

Displays your Claude AI usage limits directly in the browser toolbar as a cycling badge.

Features:
- Toolbar badge cycles through all active usage metrics every 4 seconds
- Badge mode setting: cycle through selected sources or show active only
- Popup shows progress bars for each limit: 5-Hour, 7-Day Overall, model-scoped limits (e.g. Weekly Fable), Routine Runs, and Usage Credits
- Active limit indicator shows which limit is currently constraining you
- Severity warnings with visual highlights when limits approach critical levels
- Prepaid credit balance with expiry countdown and promo tranche breakdown
- Multi-currency support — displays amounts in your account's currency
- Toggle switch on each card to show/hide that metric from the badge cycle
- Collapsible cards with chevron icons and reset times
- Lab toggle (flask icon) to reveal unknown/undocumented API codenames — if you recognise what a codename represents, please report it via GitHub Issues
- Auto-refresh (configurable: 2–30 min)
- Raw API data viewer with copy-to-clipboard
- Uninstalling the add-on will open a short feedback survey to help improve the extension

Note: This extension uses undocumented internal claude.ai APIs that Anthropic does not officially support. It may stop working if Anthropic changes their endpoints.
