FAQPage Schema
How do I take a screenshot from the command line on macOS, Linux, and Windows?▼

This screenshot utility captures desktop regions and active windows across macOS, Linux, and Windows. It routes requests to native system tools like screencapture, scrot, and gnome-screenshot, saving the output to a user-specified path or the temp directory.

Can I capture a specific window or screen region instead of the full desktop?▼

Yes, you can capture specific windows or screen regions by specifying a window ID or application name. This allows targeted region-based captures and active-window captures instead of full desktop screenshots.

Do I need to install extra dependencies to capture screenshots on macOS?▼

No extra dependencies are required. The Skill relies on built-in system capture tools like macOS screencapture, Linux scrot, and gnome-screenshot, including helper scripts to manage macOS permissions and cross-platform path resolution.

How do I specify the output path when taking a screenshot?▼

You can specify an explicit output path for your screenshot, or let the tool default to the temp directory. Automatic path handling ensures easy integration into automated workflows and visual inspection pipelines.

Why are my macOS screenshots failing during automated capture?▼

macOS screenshots often fail during automated capture due to missing screen recording permissions. The Skill includes helper scripts specifically designed to manage macOS permissions and ensure the screencapture tool functions correctly in automated workflows.
