Why delete_activity_reply is rated Critical

The high severity reflects that an AI agent could maliciously or mistakenly delete important activity records, potentially affecting collaboration and audit trails in the Huly workspace.
From the tool's definition Tool name is 'delete_activity_reply' and description states 'Delete a generic activity reply.' The verb 'delete' combined with the irreversible nature of removing activity data constitutes a destructive operation.
