WHY IT NEEDS A POLICY

Why create_client needs a policy

This tool creates a new entity (client/customer) in the business system, which is a reversible write operation. It does not execute arbitrary code, delete data, or commit financial transactions. The severity is medium because creating spurious client records could pollute the CRM database and cause downstream business process issues, but the action is not destructive and can typically be rolled back or corrected.

From the tool's definition Tool name 'create_client' and French description 'Créer un client' (Create a client) indicate the tool creates a new client/customer record in the ERP system.
