WHY IT NEEDS A POLICY

Why composite_video_clips needs a policy

Compositing multiple video clips creates new composite video output, which is a reversible Write operation (the original clips remain unchanged; the output can be deleted or regenerated). It does not execute arbitrary code (Execute), delete data (Destructive), involve financial transactions (Financial), or trigger external system operations with unpredictable effects.

From the tool's definition Tool name 'composite_video_clips' and description 'Compose multiple clips' indicate creation/combination of video data. The sibling tools (audio effects, file operations) confirm this server manipulates media files.
