# Convert Fingerprint > Develop the Fingerprint - the only-you POV / contrarian take / vivid voice moment that lives inside the Four-Layer Open and recurs across the asset. Outputs a fingerprint pack: signature moments, contrarian takes, vivid images, and seller-specific phrases that make copy unswappable. Use when copy reads "fine" but generic - when swapping the seller's name for a competitor's wouldn't change anything - and you need the distinctly-this-person voice layer. Not for the full Four-Layer Open generation (use convert-open) and not for the Voice Rules pass (use convert-voice). - Skill: `ferroxlabs/convert-fingerprint` (Agent Skill) - Install (CLI): `npx skillmds@latest add ferroxlabs/convert-fingerprint` - Raw SKILL.md: https://api.skillmd.com/api/skills/ferroxlabs/convert-fingerprint/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - License: MIT - Author: FerroxLabs (https://skillmd.com/u/ferroxlabs) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/ferroxlabs/convert-fingerprint --- # Convert Fingerprint - The Only-You POV > *"Something in the opening that could only come from YOU. An opinion. A contrarian take. A vivid image. A way of seeing the situation that's distinctly yours. This is the moment they decide you're worth their time - because you don't sound like everyone else."* - The Donahoe Method, Layer 4 of the Four-Layer Open The Fingerprint is the hardest layer in the Method to teach. It's also the one that decides whether a reader bookmarks you or scrolls on. This skill develops the only-you voice - contrarian takes, vivid images, signature comparisons, dismissive asides, opinion shrapnel - and outputs a Fingerprint pack the rest of the asset deploys throughout. The test: if you swap the seller's name for a competitor's, would anyone notice? If yes, the Fingerprint is missing. This skill makes sure the answer is no. ## When to Use Trigger phrases: "find my fingerprint", "donahoe fingerprint", "develop the only-you voice", "contrarian take", "vivid image", "what makes this sound like me", "distinctive voice moment", "layer 4 fingerprint", `/convert fingerprint `. Use when: - A draft is structurally clean and Voice-rule-compliant but reads generic - You're standing up a new seller's voice and need the distinctive layer before any asset ships - A long-form asset has the Open Fingerprint but no Fingerprint moments downstream - and the middle reads flat - Multiple drafts from different writers need a single seller voice unified Do NOT use for: - Full Four-Layer Open generation (use `convert-open` - Fingerprint is Layer 4 of that skill; this standalone develops Fingerprint *across the whole asset*) - The full Voice Rules pass (use `convert-voice` - Voice handles mechanics; Fingerprint handles distinctiveness) - Auditing existing copy (use `convert-audit`) - Brand strategy / positioning (different problem; use `funnels-pull-authority` if available) ## Inputs Required: 1. **Seller** - who is the "I" of the asset? Real human, real history, real opinions. 2. **Seller's actual opinions** - what do they actually believe about the topic that *most* people in the field don't? List 3-5 contrarian takes the seller would defend over coffee, not from a script. 3. **Seller's signature observations** - what do they notice that no one else does? Specific, vivid moments from their work. Optional: - **Existing samples of seller voice** - emails, podcasts, off-the-cuff videos. Off-the-cuff is gold; produced content is often Fingerprint-stripped. - **Competitive landscape** - who else writes about this topic? The Fingerprint differentiates against them specifically. - **Topic or asset the Fingerprint is being developed for** - `out_path` - caller-controlled output. Defaults via `build_report_path`. ## The Fingerprint (full method) The Fingerprint comes through five expression types. A strong asset deploys 3-5 across its length. ### 1. The Contrarian Take An opinion most of the field disagrees with - that the seller can defend. Specifications: - A specific, named common belief (not "common wisdom") - The seller's specific, named alternative - Defensible - not contrarian for the sake of edge Examples: - ✓ *"Most of the advice out there about email frequency is - and I'm being generous here - complete horseshit. The 'don't email more than once a week' rule was invented by people who never actually built a list that paid them. I email five times in 24 hours during a launch and the unsubscribes are nothing compared to the revenue."* - ✓ *"Everyone tells you to find your niche. I think that's exactly backward. Pick the niche that finds you back - the one that pays you for the work you'd do anyway."* - ✗ *"I disagree with conventional wisdom."* (vague, no specifics, no defensible alternative) ### 2. The Signature Comparison A vivid image or analogy that anchors a complex idea instantly. Comparison Bombs from the Transition System turned into seller signature moves. Specifications: - Specific reference (not "it's like Netflix" but "it's like a Sunday afternoon at the DMV, but the line moves") - Pulled from the seller's actual life, not from cultural cliché - Reusable - strong enough that the seller can come back to it across multiple assets Examples: - ✓ *"It's like cold-calling, except the customer makes the call - and they already have your service in their search history."* - ✓ *"Picture an agency retainer, except you keep all the margin and the customer never asks for a status meeting."* - ✓ *"Think of a launch like a cargo plane: you can load anything you want into it, but if the runway isn't long enough, you crash. Most people pack the plane perfectly and skip the runway entirely."* ### 3. The Vivid Image A specific, sensory moment that reads like film, not copy. Often from the seller's actual life. Specifications: - Sensory (sight / sound / feel / time-of-day) - Specific (named place, real moment) - Anchors a claim with film-like detail Examples: - ✓ *"It was a Tuesday in March 2019. I was at my kitchen table - the one with the chip in the corner from when my kid threw a Lego at it - staring at a dashboard that said zero. That's when I figured out the mechanism that pulled $84k out of nothing in the next 90 days."* - ✓ *"The text came in at 11:47 on a Tuesday night. Sarah had just pulled $32k in design contracts in nine days using nothing but the script in Module 6. Her message was three words: 'Holy. Shit. Mike.'"* ### 4. The Dismissive Aside A throwaway line that signals "I don't even need to argue this." High-status, calm, dismissive. Specifications: - One sentence, often parenthetical - Conveys certainty without raising voice - Rejects a competitor or alternative without naming names Examples: - ✓ *"(I know - I used to fall for that pitch too.)"* - ✓ *"Yeah. Same energy as those 'manifest your dream business' courses. We're not doing that here."* - ✓ *"Anyway."* (used after a digression - signals the seller's confidence to drop a thread mid-sentence) ### 5. The Opinion Shrapnel Short, sharp opinions dropped through the body - not load-bearing claims, just texture. Specifications: - Short (5-15 words usually) - Specific opinion stated as fact - Adds personality without slowing the read Examples: - ✓ *"Most webinars are too long, by the way."* - ✓ *"The price doesn't matter. The mechanism matters. The price is just a bill."* - ✓ *"Everybody overthinks the headline. Underthink the headline. Overthink the bullets."* - ✓ *"Most copywriters don't understand that 'short copy' isn't about word count."* ## The Fingerprint Test The single test for whether a draft has Fingerprint or not: > **If I swap the seller's name for a competitor's, does anyone notice?** If no - Fingerprint is missing. Find it. If yes - Fingerprint is working. Apply this test at the asset level (does the *whole page* have Fingerprint moments scattered?) and at the section level (does *this specific section* have at least one Fingerprint moment?). ## Workflow ### Step 1 - Mine the seller's actual opinions The Fingerprint can't be invented. It has to come from the seller. Interview-mode questions: - *"What's something most people in your space believe that you think is wrong?"* (Contrarian Take seed) - *"What's a moment in your work you'd describe scene-by-scene to a friend?"* (Vivid Image seed) - *"What's an analogy you find yourself using over and over?"* (Signature Comparison seed) - *"What do you find yourself rolling your eyes at in your industry?"* (Dismissive Aside seed) - *"Three opinions you'd defend at a dinner party."* (Opinion Shrapnel seed) If the seller can't answer these, the Fingerprint can't be developed yet - push them to do real reflection first. Don't fabricate. ### Step 2 - Sort raw inputs into the 5 types Categorize every seller answer into one of the five expression types. Most sellers will naturally produce 2-3 strong items per type. ### Step 3 - Sharpen each into Fingerprint-ready form Take each raw seller answer and sharpen: - Add the specific common belief being contradicted (Contrarian Takes) - Add the time-stamp / sensory detail (Vivid Images) - Make the analogy concrete and specific (Signature Comparisons) - Drop intensifiers and let the dismissive land flat (Dismissive Asides) - Compress to 5-15 words (Opinion Shrapnel) ### Step 4 - Apply the Fingerprint Test on each item For each sharpened Fingerprint item: could this come from a competitor? If yes, it's not Fingerprint - it's a generic line dressed up. Discard or sharpen further. ### Step 5 - Map deployment across the asset Plan where each Fingerprint moment lands: - Layer 4 of the Four-Layer Open: 1 high-impact moment (usually a Contrarian Take or Dismissive Aside) - First proof section: 1 Vivid Image - Mechanism / story section: 1 Signature Comparison + 1 Opinion Shrapnel - Bullet section transitions: 1-2 Opinion Shrapnel - Pre-close section: 1 Vivid Image or Internal Moment - P.S. or P.P.S.: 1 Dismissive Aside ### Step 6 - Bullshit Filter Read each Fingerprint moment aloud. Does it sound like *this specific seller*? If it could come out of any influencer in the niche, kill it. ## Examples - building a Fingerprint pack ### Seller: Mike Donovan, ex-plumber turned LSA-for-trades coach **Raw seller input:** *"I think most of the marketing for tradespeople is built by people who've never held a wrench. They sell $3k Facebook ads packages to plumbers like it's the same play as DTC e-commerce."* **Sharpened Contrarian Take:** > *"Most of the marketing being sold to tradespeople is built by people who've never held a wrench. They sell $3k Facebook ads packages to plumbers like it's the same play as e-commerce - except plumbers don't sell impulse buys at 11pm. Plumbers sell to people whose pipes just burst on a Tuesday at 6am. Different mechanism. Different platform. Different everything."* --- **Raw seller input:** *"There was a moment when I realized LSA was going to change my business - I was at the kitchen table looking at the dashboard."* **Sharpened Vivid Image:** > *"It was a Wednesday in October. I was at the kitchen table at 5:47am, drinking coffee from the mug my daughter painted that has a chip in the rim, looking at the LSA dashboard. Eleven verified-intent calls had come in overnight. I'd been in this business nine years and never had eleven calls in a single Tuesday, let alone overnight while I was asleep. That's the moment I knew."* --- **Raw seller input:** *"I always say it's like the trucks have their own salesman now."* **Sharpened Signature Comparison:** > *"It's like every truck in your fleet got its own salesman - except the salesman never sleeps, never asks for a raise, and only talks to people who already have your service in their search history."* --- **Raw seller input:** *"Don't get me started on the 'mindset' coaches."* **Sharpened Dismissive Aside:** > *"(I'm not going to do the 'mindset' bit. You don't need a mindset coach. You need ten more booked jobs this month.)"* --- **Raw seller input:** *"Most operators overprice their first jobs."* **Sharpened Opinion Shrapnel:** > *"Most operators overprice their first ten jobs. Underprice them. Bank the reviews. Reviews compound - your prices don't, until they have to."* ## Output template ```markdown # Fingerprint Pack - **Seller:** **Topic / niche:** **Asset(s) this pack feeds:** --- ## The 5 Expression Types - Fingerprint inventory ### Contrarian Takes (2-4) 1. > 2. > 3. > ### Signature Comparisons (2-3) 1. > 2. > ### Vivid Images (2-3) 1. > 2. > ### Dismissive Asides (3-5) 1. >
