WHY IT NEEDS A POLICY

Why change_video_speed needs a policy

This tool transforms video properties in a way that changes the output artifact (the video file) but the modification is reversible—the original can be recovered or the speed can be changed again. It does not execute arbitrary code, delete data irreversibly, or perform financial transactions. It fits the Write category as it creates a modified version of video data.

From the tool's definition Tool modifies video content by changing playback speed, which alters the video file itself (a reversible modification). The description '改变视频播放速度' translates to 'change video playback speed', confirming it modifies existing video data.
