WHY IT NEEDS A POLICY

Why START_TRANSCRIPTION_JOB needs a policy

This tool initiates an external transcription service operation. While it doesn't execute arbitrary code or delete data, it does trigger a third-party API operation whose outcome and resource consumption depend on user-supplied arguments (file selection, format, etc.).

From the tool's definition Tool name is START_TRANSCRIPTION_JOB; description in Japanese states '指定されたファイルで書き起こしジョブを起動します' (Start a transcription job with a specified file). This triggers an external operation (transcription job) whose effects depend on the file argument provided.
