Why batch_update_presentation is rated Medium
This tool creates or modifies data reversibly within Google Slides presentations. While updates are not destructive (data is not irreversibly deleted), they do alter existing content. Severity is high because batch operations on presentations could affect large amounts of shared organizational content, and misuse by an AI agent could corrupt or deface important documents accessed by multiple users.
From the tool's definition Tool name 'batch_update_presentation' and description 'Apply batch updates to a Google Slides presentation' indicate the tool modifies existing presentation content.
