What this skill does

Gathers the facts of an unpaid invoice in one interview round, then drafts a demand letter from the model in references/models/demand-letter.md.

Interview

Ask all of these in one message before drafting. Do not draft while an answer is missing, and never invent a fact:

• Who is the creditor and who is the debtor (names and addresses)?
• Invoice number, amount with currency, and the original due date?
• Were earlier reminders sent, and when?
• What payment deadline should the letter set?
• What happens after the deadline — default interest, court action, handover to counsel?

Drafting rules

• Follow references/style.md for tone, dates, and amounts.
• Start from references/models/demand-letter.md and keep its section order.
• State consequences factually; announce only steps the creditor actually intends to take.
• Mark anything not confirmed in the interview as [TO CONFIRM].

Output

The letter, ready to paste onto letterhead, followed by an "Open questions" list containing every [TO CONFIRM] item.

Reference index

• references/style.md — tone, structure, and formatting rules for the letter
• references/models/demand-letter.md — the model letter to imitate

Workflow

1. Ask the interview questions; wait for the answers.
2. Draft from the model, applying the style rules.
3. End with the open-questions list.
