WHY IT NEEDS A POLICY

Why siigo_create_invoice_batch needs a policy

This tool creates multiple invoices in batch, which are reversible write operations (via siigo_annul_invoice as evidenced by sibling tools). However, invoices represent binding financial documents in an accounting system that trigger downstream financial workflows. The batch nature amplifies risk—a single misuse could generate dozens of incorrect invoices simultaneously.

From the tool's definition Tool name contains 'create' and description states 'Create invoices in batch asynchronously.' Invoices are financial documents that commit accounting transactions and revenue recognition in Siigo accounting software.
