Delete a shape from a slide by its 0-based index.
AI agents call pptx_delete_shape to permanently remove resources in Pptx — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes shapes from PowerPoint slides without a reversible alternative. Deletion operations are irreversible and cannot be undone programmatically through standard MCP mechanisms, making it a destructive action. While the blast radius is limited to a single presentation object rather than an entire file, the irreversibility and data loss nature justify the Destructive category over Write.
From the tool's definition Tool name 'pptx_delete_shape' and description 'Delete a shape from a slide by its 0-based index' explicitly use the term 'Delete', which performs irreversible removal of presentation content.
