The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes native OS commands such as screencapture, scrot, gnome-screenshot, and import through subprocess calls to perform screenshot captures. It also uses osascript on macOS to interact with running applications.
[DYNAMIC_EXECUTION]: The skill uses runtime compilation and execution for platform-specific tasks. The PowerShell script (take_screenshot.ps1) uses Add-Type to compile C# helper methods for Win32 API access, and the macOS scripts execute Swift code using the swift interpreter to manage permissions and window information.
[INDIRECT_PROMPT_INJECTION]: The skill is susceptible to indirect injection through user-controlled parameters such as application names and file paths.
Ingestion points: User-provided strings for the --app, --window-name, and --path arguments in the Python and PowerShell scripts.
Boundary markers: Explicit boundary markers are not used for these inputs.
Capability inventory: The skill can execute system commands for screen capture and write files to the local file system.
Sanitization: The Python script includes logic to escape double quotes in application names before they are used in AppleScript commands, providing a basic level of protection.
