RISK

Why create_invoice_from_estimate is rated Medium

This tool creates an invoice, which is a Write operation (generating a new record). While invoices are financial documents, this tool does not move money or commit payment obligations directly — it only creates the invoice document. The Financial category applies to tools that actually move money or commit financial obligations (e.g., charging a card, initiating a payment).

From the tool's definition 'Create an invoice from an estimate' — creates a new financial document (invoice) based on an existing estimate
