AI agents call video_studio_review_video to retrieve information from LocalAnt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs inspection/analysis of rendered video files using ffprobe, which is a standard media inspection tool that queries and reports on video properties without modifying content. This is purely informational (Read category) with minimal risk—an AI agent could learn video properties but cannot alter files, execute arbitrary commands, or cause side effects beyond reading metadata.
From the tool's definition Tool name contains 'review', description uses 'ffprobe' (a read-only multimedia inspection utility), and no modifying operations are described.
