Claude Sentinel

Claude Sentinel is an open-source Python script that monitors your Claude AI usage and instantly sends push notifications to your phone the moment your 5-hour usage window resets. It uses event-driven hooks integrated with Claude Code, cloud alarms via Upstash QStash, and delivers notifications through Telegram, ensuring timely alerts even when your computer is off or asleep. It requires setup of a Telegram bot and Upstash QStash account but involves zero dependencies and is fully customizable.
