What is codex-full-output?

codex-full-output is an unofficial Windows patch for OpenAI's Codex desktop app that fixes two display limits in its interface. Normally the app shows tool output inside a small fixed height box with its own scrollbar, and cuts long shell commands off after two lines. This patch adds two new settings under the app's Appearance preferences that expand tool output to its full height and show complete shell commands without truncation, and both are turned on by default after installing. The project is not affiliated with OpenAI or Microsoft. Rather than modifying the version of Codex installed through the Microsoft Store, it downloads the official installer package separately, extracts it into its own standalone folder outside the Store's protected location, and injects a small CSS file and a JavaScript file into the app's packaged code to change how tool output and commands are displayed. It then creates a launcher and optional shortcuts for this separate copy, leaving the Store installed version untouched. To install it you need Windows 10 or 11 on a 64 bit machine, PowerShell 5.1 or newer, and Node.js available on your system path. You download or clone the repository and run the included installation script, which asks where to install the standalone copy. Running the installer again later updates the standalone copy to a newer Codex version, and if the update process fails partway through, the previous working copy is restored automatically. A separate uninstall script removes the standalone copy and any shortcuts it created, but only if it recognizes the folder as one it installed itself, and it sends the files to the Recycle Bin rather than deleting them immediately. The author documents exactly how the installer verifies the downloaded package's signature and identity before patching it, and lists known limitations, including that it only works on Windows, and that launching the standalone copy may close another open Codex window since the app only allows one running instance at a time.
