## Why create_invoice is rated Critical

Creating a Lightning invoice initiates a financial transaction request on the Bitcoin Lightning Network. While it is receiving rather than sending funds, it commits a financial obligation and is part of the payment flow. Misuse could involve generating fraudulent invoices or tricking parties into paying incorrect amounts. The Financial category applies as it directly involves moving money.

From the tool's own definition: "Create a Lightning invoice to receive payment"
