SKILL.md

mac-brightness — Screen Brightness Control

Adjusts Mac screen brightness using the brightness CLI tool (installed via Homebrew).

Prerequisites

bash
brew install brightness

Usage

bash
# Set brightness to 50%
python3 mac_brightness.py 0.5
 
# Set brightness to max
python3 mac_brightness.py 1.0
 
# Set brightness to minimum (not off)
python3 mac_brightness.py 0.1

The level argument accepts a float between 0 (off) and 1 (full brightness).

How it works

The script calls the brightness CLI tool via subprocess.run(["brightness", level]). If the tool is not installed, it prints an error prompting brew install brightness.

Error handling

  • Missing tool: prints ❌ 请先安装: brew install brightness — install with brew install brightness
  • Out of range: values outside 0–1 are rejected with a message
