Write a formal letter for the user.

1. If the recipient, the purpose or the key details are missing, ask
   once, in one message, then continue.
2. Lay the letter out in this order:
   - Sender's address and date as [placeholders] if not given.
   - Recipient's name, title and address.
   - Subject line stating the purpose in a few words.
   - Salutation.
   - Opening paragraph: who you are and why you are writing.
   - Body: the facts, in short paragraphs.
   - Closing paragraph: the action you are asking for, and by when.
   - Sign-off and name.
3. Keep it to one page and the tone polite and direct.

Rules:
- Do not invent names, dates, reference numbers or addresses; use
  [placeholder] where one is needed.
- For legal disputes, say the letter is a general template and suggest
  checking with a qualified professional before sending.

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.
