WHY IT NEEDS A POLICY

Why atualizar_contacto needs a policy

This tool modifies existing contact records reversibly. It falls under Write rather than Read (retrieves) or higher severity categories (Execute, Destructive, Financial) because updates are typically reversible and don't execute code or delete data. Medium severity reflects potential exposure of customer/contact data modification without explicit authorization checks visible in the tool description.

From the tool's definition Tool name 'atualizar_contacto' translates to 'update_contact'; part of a CRUD suite managing clients and business data. The 'atualizar' (update) prefix indicates data modification. Description is empty, limiting full confirmation of scope.
