RISK

Why create_ai_mask is rated Medium

This tool modifies photo metadata/settings by creating a mask, which is a standard non-destructive edit in Lightroom Classic. It does not execute arbitrary code, delete data, or perform financial operations. The reversible nature of mask creation (typical in Lightroom's non-destructive workflow) places it in the Write category.

From the tool's definition Tool description states 'Create an AI-powered mask on the active photo.' The verb 'create' indicates data modification.
