The Agent Skills Directory

[COMMAND_EXECUTION]: The script scripts/frame.sh executes the ffmpeg binary to extract frames from video files, which is the primary intended function of the skill.\n- [EXTERNAL_DOWNLOADS]: The skill metadata specifies the installation of the ffmpeg formula via the Homebrew package manager, which is a well-known and trusted service.\n- [PROMPT_INJECTION]: The skill exhibits an indirect prompt injection surface within the scripts/frame.sh script.\n
Ingestion points: The script takes several user-controlled inputs, including file paths (in, out), a timestamp (time), and a frame index (index) via command-line arguments.\n
Boundary markers: No specific delimiters or boundary markers are implemented to prevent input from being interpreted as instructions by the underlying tool.\n
Capability inventory: The script has the capability to execute a powerful command-line tool (ffmpeg) with these user-provided inputs.\n
Sanitization: While shell variables are double-quoted to prevent basic shell word-splitting and globbing attacks, the script does not validate the content or format of the time and index variables before interpolating them into the ffmpeg command or filter strings.
