## Why get_invoice is rated Low

This tool retrieves invoice information without creating, modifying, deleting, or executing any side effects. It is a simple data retrieval operation. The low severity reflects minimal blast radius even if an AI agent misuses it—at worst, it could access invoice details that may be sensitive but cannot cause financial transactions or data loss.

From the tool's own definition: "Tool name 'get_invoice' and description 'Retrieve details of a specific invoice' indicate a read-only operation that queries existing data without modification."

## Use case

AI agents call get_invoice to retrieve information from PayPal without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
