brightness-cli

A command‑line utility for adjusting the display’s brightness on Windows systems. After installing globally via npm, the tool can be invoked with the `brightness` command; running it without arguments shows the current level, while providing a numeric value such as `0.8` sets the brightness to that proportion of the maximum. The interface includes a help flag (`--help`) that documents usage options.

The program is built on top of the `brightness` package, which provides the underlying API for interacting with the operating system’s brightness controls. It is packaged as a stable, core CLI tool and is distributed under the MIT license, allowing unrestricted use and modification.

Developers who need a quick, scriptable way to query or modify screen brightness from the terminal can incorporate this utility into automation scripts or development workflows on Windows machines.
