FerroxLabs Write a full long-form direct-response sales letter using The Donahoe Method, end-to-end. Diagnose temperature, the Four Questions, and the Three Locks, then write the four-layer open, the body, and the Cascade Close, Filter the close, and assemble the complete letter. The user reviews at each major beat.
Step 1: Capture the offer and prospect (uses: convert-temperature)
Ask the user for the offer in one sentence and the target prospect in one sentence. Capture both before any diagnosis. Set expectations that they will review at the major beats (open, body, close).
- Input: user-supplied offer sentence and target-prospect sentence
- Output: the captured offer-and-prospect brief
- Key focus: get a crisp offer and prospect to anchor every downstream beat
Step 2: Infer the audience temperature (uses: convert-temperature)
Infer the audience temperature (cold, warm, hot) from the offer and prospect. State the temperature, the reasoning, and the Method implication. Temperature is the most-skipped, most-consequential decision in DR copy: wrong temperature means wrong everything downstream. Let the user confirm or override.
- Input: the offer-and-prospect brief
- Output: the confirmed audience temperature with its Method implication
- Key focus: lock temperature first because it calibrates the whole letter
Step 3: Diagnose the Four Questions (uses: convert-four-questions)
Run the Four Questions diagnostic for this offer and prospect: Why You, Why Me, Why This, Why Now. State the answers and reasoning, calibrated to temperature. Ask the user to confirm or refine.
- Input: the offer-and-prospect brief and the temperature
- Output: the confirmed Four Questions diagnosis (Why You / Why Me / Why This / Why Now)
- Key focus: answer all four before structuring the letter
Step 4: Diagnose the Three Locks (uses: convert-three-locks)
Break the prospect down by the Three Locks: Want, Trust, Excuse. Every section of the letter is engineered to break one of these locks, so lock the diagnosis here. State the Want/Trust/Excuse breakdown and the reasoning, informed by temperature and the Four Questions, and confirm with the user.
- Input: offer-and-prospect brief, temperature, Four Questions
- Output: the confirmed Want / Trust / Excuse breakdown
- Key focus: the locks diagnosis the entire structure flows from
Step 5: Write the four-layer open (uses: convert-open)
Write five ranked Four-Layer Opens for this offer, calibrated to temperature and the Three Locks. Present them ranked with Method reasoning. Ask the user to pick one, refine, or request more variants; if they want a different angle, refine the opens from their feedback (up to three passes) before proceeding.
- Input: offer brief, temperature, Three Locks
- Output: five ranked Four-Layer Opens and the user's chosen open
- Key focus: a strong, temperature-calibrated open the user commits to
Step 6: Write the body (uses: convert-package)
Write the body sections in body-only mode: bullets, proof stack, and the three-locks sequence, building on the chosen open. Calibrate to temperature and the locks. Present the body and ask the user to proceed to the close or refine; if they refine, iterate from their feedback (up to three passes).
- Input: offer brief, temperature, Three Locks, the chosen open
- Output: the approved body (bullets, proof stack, three-locks sequence)
- Key focus: a body that breaks each lock in sequence and earns the close
Step 7: Write the Cascade Close (uses: convert-close)
Write the Cascade Close for the letter, building on the body and the Three Locks: Stack to Vision to Math to Safety Net to Door, plus P.S. and P.P.S. Address every buyer type. Show the close.
- Input: offer brief, the body, Three Locks
- Output: a full Cascade Close covering all seven beats
- Key focus: close every lock and buyer type the letter has set up
Step 8: Filter the close, review, and assemble (uses: convert-bullshit-filter)
Run the Bullshit Filter on the Cascade Close and present the flagged lines alongside the close. Ask the user to assemble the complete letter or refine the close; if they refine, iterate from their feedback (up to three passes), Filtering again, until they approve. Then assemble the complete sales letter: temperature, Four Questions, Three Locks, open, body, close, and the Filter pass.
- Input: the Cascade Close, offer brief, body, user refinement feedback
- Output: the Filter pass and the assembled complete sales letter document
- Key focus: clean the close, then package the full letter end-to-end
