Agent Usage Sentinel

Cross-tool quota and reset alerts for developers juggling Claude Code and Codex

Problem

Heavy AI-coding users constantly hit the five-hour limit mid-task: the thought is still in their head but the tool has stopped. Usage is only visible in the terminal or a web page, so it disappears the moment they leave the desk, and each agent (Claude Code, Codex, etc.) has its own windows to track separately.

Solution

A small local aggregator that reads usage data from each CLI/API and puts all windows—5-hour, weekly—plus reset countdowns on one panel, with 80%/95% threshold system notifications and a menu-bar presence. Data stays local.

Users

Indie developers and small teams subscribing to multiple AI coding tools

MVP

Support Claude Code and Codex usage sources; one-screen view of window percentages and reset countdowns; one-shot threshold alerts with mute; menu-bar presence; optional daily CSV export

Revenue

One-time purchase with a year of updates, plus team multi-seat licenses; later a per-seat team usage dashboard via API billing

Why now

AI coding has entered a window-throttled subscription era, quota anxiety is high, and big vendors won't build a cross-platform aggregator; indie developers are their own target users and the data sources are simple
