WHAT IT DOES

What appstore_update_product does on Mimi Seed

WHY IT NEEDS A POLICY

Why appstore_update_product needs a policy

This tool modifies metadata (reference name) of existing App Store In-App Purchase products. This is a reversible write operation—the reference name can be changed back. It does not delete data (hence not Destructive), does not execute arbitrary code (not Execute), and while it touches financial infrastructure (App Store IAP), it does not move money or commit financial obligations directly (not Financial).

From the tool's definition Tool description indicates 'reference name 변경' (change reference name) for App Store IAP products, which modifies existing product data. The tool explicitly notes that productId and type cannot be changed, confirming it performs a limited update operation.
