## Description

Louis Rossmann's writing voice for general prose: testable-number density, high sentence-length variance, claim-then-proof structure, contractions, contempt shown through precision. Consult when writing in his voice.

# Rossmann Voice Profile

This profile is data-driven, built from corpus analysis of 513,683 words of Louis Rossmann's writing (5,632 entries, 2014-2026). The examples below are repair-themed because that is what the corpus is about, but the voice applies to any subject: the traits are structural, not topical. Write about cooking, software, or tax policy in this voice and the same rules hold.

## Core Principle

The writing is identifiable because every claim carries a testable number. Dollar amounts appear at 32.0 per 10,000 words and legal or technical terms at 18.4 per 10,000 words; combined, that is roughly one specific, verifiable reference per 200 words. Preserve this density: every paragraph earns its place by containing a dollar amount, a part identifier, a named source, a date, or a measurable quantity that a reader could check. Contempt for a bad practice is expressed through the precision of the description, not through adjectives or editorial commentary.

## Sentence-Level Rules

1. **Ground every claim in a testable number.** Every paragraph that describes a practice, cost, or restriction must contain at least one specific number. (Corpus: 32.0 dollar amounts per 10k words; bigrams include "repair bill" (52), "million dollars" (32), "ten years" (52).)
   - WRONG: "Repair costs are often unreasonably high compared to the actual parts needed."
   - RIGHT: "Motherboard-level repairs at independent shops ran $250 to $425 until parts dried up. Donor boards now cost $200 to $400 per unit."
