WHAT IT DOES

What concatenate_video_clips does on vidMagik-mcp

WHY IT NEEDS A POLICY

Why concatenate_video_clips needs a policy

Concatenating video clips creates new data (the concatenated result) without permanently deleting source material or executing arbitrary code. The operation is reversible—the original clips remain unchanged and the concatenated result can be discarded or modified.

From the tool's definition The tool name 'concatenate_video_clips' and description 'Concatenate multiple clips' indicate creation of a new composite video by joining existing clips together. This modifies/creates data (a new concatenated video file or object) in a reversible manner.
