    Why it is in this group

    • The name "create_invoice" says "create": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

      What this check looks for
    Description, as the server wrote it
    Use this when the user wants to make, create, generate or send an invoice, bill, quote, estimate or receipt, or asks for an "invoice PDF" or "invoice template filled in". Calculates line totals, tax, discount and shipping and returns a download link to a print-ready PDF plus the totals. Ask for missing essentials (who it is for and the items with prices) before calling; the seller details are optional.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
    • idempotentHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
