Chrome MV3 extension for tracking AI assistant usage from signed-in provider pages. It currently supports Claude at https://claude.ai/settings/usage and Codex at https://chatgpt.com/codex/cloud/settings/analytics#usage.

- Finds existing provider usage tabs, or opens them in the background.
- Reads visible weekly usage percentages from signed-in pages.
- Stores the latest snapshot in
chrome.storage.local. - Shows the highest projected weekly usage risk on the extension action badge.
- Shows current usage, projected usage, reset details, and provider rows in the popup.
- Refreshes on extension startup, one minute after the refresh alarm is created, every 30 minutes after that, and whenever the popup refresh button is clicked.
The provider scrapers live under src/providers/. Badge text, colors, title text, icon drawing, and provider-risk selection live in src/badge*.js, so future badge visuals can change without rewriting provider extraction or tab orchestration.

Recent branded Google Chrome builds ignore --load-extension. For automated loading, use Chromium or Chrome for Testing:
nix develop -c just run-chromiumThen pin the extension and open the popup or wait for the refresh alarm. The extension needs authenticated provider sessions in that browser profile.
