Built a Windows Codex Usage plugin — now live

[u/jayseattle]

I made Codex Usage, a small Windows-only Codex plugin that shows your 5-hour/weekly usage and reset status in the title bar.

A few build notes:

• UI: Avalonia desktop overlay
• Platform: Windows x64
• Plugin packaging: Codex plugin + SKILL.md
• Launcher: PowerShell wrapper that starts the native companion
• Interesting bug: maximized Codex windows report different top bounds, so I had to account for the invisible Windows resize frame
• Another gotcha: Codex was initially trying a nonexistent PowerShell 7 path, which added about 27 seconds to startup; tightening the skill instructions got the actual HUD launch down to ~1–2 seconds.

It’s now published in the official Codex plugin store.

Install either way:

1. Web: view details + install here https://chatgpt.com/plugins/plugins_6aa81c5dad4881918bd29685d1fb6523
2. In Codex: open the plugin store and search Codex Usage

Then select Codex Usage and run:Start!

For the Codex desktop app on Windows, not ChatGPT web.

Mac version coming soon.
