    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it

    Description, as the server wrote it
    Build a complete invoice as structured data: invoice number, issue and due dates, line items, discount, tax, total and payment terms. Nothing is stored. Use when the user wants an invoice for a client. Do NOT use for totals only (use calculate_totals) or for a printable text version (use render_invoice_text).

    Description, as the server wrote it
    List the currency codes InvoiceGen accepts for invoices (USD, EUR, INR, GBP, AED, SGD, AUD, CAD). Use before create_invoice when unsure whether a currency is supported. No exchange rates or currency conversion are provided.

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.
