thrr87/codex-limits ? reverse-engineered prompt

Build me a lightweight macOS menu bar app that helps me keep an eye on my Codex usage and pace it until it resets.

I want the menu bar icon to always show the current remaining percentage, and when I click it, a popover should show the reset time, a suggested pace, a simple burn down chart, and a plain language status like Slow down, On track, or Room to use more. It should read the local Codex CLI usage info, keep a local history of samples, and compare my actual usage against a safe target path with a small adjustable buffer. Make it feel native on macOS, use Swift and SwiftUI, and keep everything local first with no analytics or extra network stuff. If you need to check current docs for anything, go ahead and look them up.
