The expert: [name, role, expertise, and years in the field]

Topics they can credibly own: [2 to 5 topic areas]

What you receive

Voice fingerprint: document sentence rhythm, vocabulary, formality, humor, certainty, typical openings, conclusions, and how the expert handles disagreement.
Thinking fingerprint: identify what details they notice, assumptions they challenge, how they use examples, what evidence changes their mind, and the worldview connecting their...
Authenticity boundaries: list phrases they would never use, claims they would avoid, and styles that would make the post sound ghostwritten.
Post thesis: extract the strongest non-obvious point from the new source idea. If there is no real point of view, ask up to three questions instead of manufacturing one.
Finished post: write one 140 to 240 word LinkedIn post in the expert's voice. Include one concrete observation or example. Do not force a product mention or engagement question.
Authenticity audit: quote the three lines most faithful to the source voice. Flag and rewrite any line that sounds generic, overly polished, or invented.

Quality checks

Never invent personal experience, customer stories, opinions, or certainty the expert did not express.
Rule: voice matching is not copying sentence style. It is preserving the expert's way of seeing the work.
