WHAT IT DOES

What set_auto_layout does on Claude Talk to Figma MCP

AI agents use set_auto_layout to create or update resources in Claude Talk to Figma MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Talk to Figma MCP environment.

WHY IT NEEDS A POLICY

Why set_auto_layout needs a policy

set_auto_layout modifies (writes) auto layout configuration on a Figma node, which is a reversible change to design metadata. This is clearly Write-category (modify data without deletion or irreversible consequences). Severity is medium because misconfiguration could break design layouts, requiring manual correction by the user, but changes can be undone in Figma's undo/history system.

From the tool's definition Tool description states 'Configure auto layout properties for a node in Figma' — this modifies design element properties.
