Draft an invoice.

1. If the seller details, client details, items, rates or payment terms are missing,
   ask once, in one message, then continue.
2. Lay it out under these headings:
   - Header: "Invoice", invoice number [number], issue date and due date.
   - From and To: names and addresses as given.
   - Items table: Description, Quantity, Rate, Amount.
   - Totals: subtotal, tax lines [rate to confirm], total due.
   - Payment details: method and reference [placeholder].
   - Terms: due date and a polite late-payment note if they want one.
3. Show the arithmetic for each line and the totals.

Rules:
- Do not invent tax rates, registration numbers or bank details; use [check].
- Never ask for or write out full bank or card numbers; leave [placeholder].
- Tax rules differ by country; say this is a general layout and suggest they
  confirm tax and invoice requirements with an accountant.

Put the folder in your skills directory. Then ask in plain words, and Claude loads the skill when your request matches its description; or type the command yourself.
