jens-duttke/usage-monitor-for-claude — reverse-engineered prompt

Build me a small Windows tray app that shows my Claude usage limits in real time, without needing setup every time. I want it to use my existing Claude Code login, read the local Claude credentials, and show how much of my session and weekly limits I’ve used.

The tray icon should always give a quick percentage view, and when I click it I want a simple popup with account info, usage bars, reset countdowns, and warnings when I’m using Claude faster than the time remaining. Right click should have basic options like open popup, start with Windows, restart, quit, and maybe a GitHub link.

Please make it portable as a single Windows EXE if possible, not an Electron app. It should be safe and easy to audit, only talk to Anthropic, not log tokens, and keep credentials local. Add sensible defaults, but allow an optional JSON settings file for colors, polling, alerts, language, and custom commands when limits reset or thresholds are hit.
