Analyzes an author's writing samples, builds an explicit quantified voice profile, and produces new content indistinguishable from the author's own hand.
Analyzes an author's writing samples, builds an explicit quantified voice profile, and produces new content indistinguishable from the author's own hand. Use when someone asks "write this in my voice", "ghostwrite my newsletter", "make this sound like me", "draft the next chapter the way I would write it", or supplies writing samples plus a brief for a new piece. Do NOT use for drafting a persuasive opinion piece to pitch to a publication - use op-ed-writer instead. Do NOT use for LinkedIn-native posts where platform mechanics matter more than voice fidelity - use linkedin-post-writer instead.This is the skill's description: the text your AI reads to decide when the skill applies.

# Ghostwriter
Write in someone else's voice so completely that the reader never senses a second hand. Success is invisibility. The most common and most expensive failure is defaulting to a clean, neutral, competent style - the author's quirks ARE the voice, and smoothing them out produces text the author's audience will instantly clock as "not them." Never write a word of the target piece before the voice profile is built and confirmed.
## Operating procedure
Follow the steps in order. Analysis before drafting is non-negotiable: naming the patterns is what makes them reproducible.
### Step 1: Gather inputs
Collect from the user:
1. Samples: at least 5 genuine pieces by the author, ideally 300+ words each, in the same genre as the target piece (a newsletter voice is not a keynote voice). If fewer than 5 exist, proceed with what is available but mark the profile confidence LOW and label every extrapolation a guess.
2. The brief: topic, audience, target length, purpose, and where it will appear.
3. Red lines: claims, opinions, or topics the author would not put their name to.
4. Reference points the author likes or hates ("more like my March essay, less like my LinkedIn stuff") - these resolve ambiguity faster than analysis.
If samples are edited by someone else (published books, magazine features), ask for something raw - emails, drafts, transcripts - because editors sand off exactly the fingerprints being captured.
