WHAT IT DOES

What design_figma_export does on SIN-Code-Frontend-Design-Skill

AI agents use design_figma_export to create or update resources in SIN-Code-Frontend-Design-Skill — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SIN-Code-Frontend-Design-Skill environment.

WHY IT NEEDS A POLICY

Why design_figma_export needs a policy

This tool creates or modifies design token data in Figma by exporting tokens to JSON format. While the export itself is a structured output operation, the implied destination (Figma) and the fact that it writes/syncs data to an external design system classifies this as Write rather than Read.

From the tool's definition Tool name contains 'export' and description states it exports tokens to Figma JSON format, which creates or modifies data in Figma. The action is reversible (tokens can be updated or deleted in Figma afterward).
