System Info Skill is a Codex skill that answers the question of what hardware and software your own computer is running, without needing you to open a system settings panel or run confusing terminal commands yourself. It works on macOS, Windows, and Linux, and only ever reads information: it does not install anything, change any settings, delete files, or request elevated permissions. Once installed as a Codex skill, you can simply ask it in plain language, such as what your computer's specs are, how much disk space you have left, or whether your machine is suitable for programming and running AI locally. It also has a script you can run directly if you would rather query it yourself, with options to check the whole system or just one part, like storage, memory, CPU, or graphics. The tool reports information like your device brand and model, operating system version and architecture, processor model and core count, memory totals, disk capacity and usage per partition, and graphics card details when available. On Linux, the level of detail depends on what the display driver exposes. Wherever a field truly cannot be read, the report says so plainly instead of guessing at a value. Privacy is treated as the default. The serial number is shown with only its last four digits visible unless you explicitly ask for the full value, and the current username is hidden by default too, both on screen and inside the device name. The tool never outputs a hardware UUID, machine ID, MAC address, or IP address, and it does not read the contents of your personal files or scan private folders. Every command it runs is fixed and read only, executed without a shell and with a timeout, using only Python's standard library. The output is a clearly organized markdown report meant to be understandable by someone with no technical background, ending with a short plain language summary of what the machine is suited for.
