steipete/codexbar ? reverse-engineered prompt

Build me a small macOS menu bar app that shows my AI coding usage at a glance, especially for Codex and Claude Code.

I want to see how much I’ve used, when the current limit resets, and a simple visual indicator in the menu bar so I don’t have to open each service and guess. It should feel lightweight, with no Dock icon, and the main view should just be a clean popover with usage bars, reset countdowns, and any important status warnings.

It should reuse whatever sign in info I already have on my Mac, like browser sessions, CLI sessions, API keys, or local files, so I’m not creating new passwords or logging in again.

If it makes sense, include a way to add more providers later, and a compact mode that shows one icon for everything. Look up current docs online if you need to, and make it work nicely on macOS 14 and newer.
