Why download_transcription is rated Low
Downloading a transcription is fundamentally a read operation: it accesses and retrieves data that already exists. There are no side effects, data is not modified or deleted, and no external operations are triggered. The tool fits clearly into the Read category. Severity is low because transcription data, while potentially sensitive, is merely being retrieved by the authorized user without irreversible consequences.
From the tool's definition Tool description states 'Download call transcription as a text file' — this is a retrieval operation that retrieves existing transcription data without modification, deletion, or triggering external actions.
