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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. …

How to install
mdr add skillmedev/skills/ghostwriter@sha256:cf3ae89dac62bb84The line at the top of this page pins the label git:20261005.bea4ea5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
