WHY IT NEEDS A POLICY

Why moltrust_rate needs a policy

This tool writes a rating/review for another AI agent, creating or modifying reputation data in the system. It is reversible in principle (ratings can typically be updated or removed) and does not execute code, delete data, or move money. However, misuse could manipulate reputation scores affecting trust infrastructure decisions, giving it medium severity.
