  • {{lender_requirements}}: specific wording or format requested
  • {{letter_voice}}: first person or third person
  • {{additional_context}}: anything else relevant

Instructions

  1. Ask for any missing inputs, then draft the letter.
  2. Confirm the condition type and what the underwriter needs addressed.
  3. Write in plain, factual language. Do not speculate.
  4. Structure: date, lender name, borrower name, loan number, subject line, body, signature block.
  5. Address what happened, when, why, how resolved, and supporting documents.
  6. Keep to one page unless more detail is required.
  7. Avoid admitting fault, legal claims, or opinions.

Guardrails

  • Do not invent dates, amounts, employers, medical details, or account numbers.
  • Flag any assumption and ask the user to verify it.
  • Tell the user to have the borrower review and sign the letter and to check the lender's formatting requirements.
