WHY IT NEEDS A POLICY

Why invent_recipe needs a policy

This tool generates/creates a new recipe in a structured format based on provided ingredients. It produces new content (a recipe) which constitutes a Write operation. No deletion, execution of code, or financial transactions are involved. Severity is low as the worst case is generating an irrelevant or incorrect recipe with no significant blast radius.
