## Why generate_invoice_number is rated Medium

This tool creates/generates a new invoice number, which is a reversible write operation. It does not charge money, process payments, or delete data. The severity is low because generating invoice numbers has minimal blast radius—it creates metadata without financial transactions or data destruction.

From the tool's own definition: "Tool name 'generate_invoice_number' and description 'Generate a unique invoice number' indicate creation of a new invoice identifier resource."

## Use case

AI agents use generate_invoice_number to create or update resources in Ghl, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ghl environment.
