WHAT IT DOES

What photoshop_scale_layer does on Photoshop MCP Windows-First

AI agents invoke photoshop_scale_layer to trigger actions in Photoshop MCP Windows-First. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why photoshop_scale_layer needs a policy

This tool triggers an external operation (Adobe Photoshop layer scaling) whose effects depend on the percentage argument provided. While the changes are reversible (via undo), the tool executes a command with visual/structural side effects on the document.

From the tool's definition "Scale the active layer by a percentage" — this action modifies the visual content and dimensions of a Photoshop layer, executing a transform operation that affects the document state and requires Adobe Photoshop to process the scaling command.
