WHY IT NEEDS A POLICY

Why generate_brand_tokens needs a policy

The tool generates (creates) design tokens, which are new data artifacts added to the design system. This is a reversible Write operation—tokens can be regenerated, updated, or removed without permanent data loss. It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's definition Tool name 'generate_brand_tokens' and description 'Generate design tokens from brand identity metadata' indicate creation of new design artifact data derived from existing metadata.
