Reverse-engineer a brand's verbal identity — voice, tone, structure, hooks, CTAs, offer framing, emoji/hashtag policy, formality, person, language mix — from a corpus of existing copy (social captions, blog/long-form articles, ad copy, website page copy). Produces a structured voice guideline plus a per-channel "voice prompt block" for on-brand AI copywriting. Use this whenever the user wants brand voice, writing style or tone-of-voice analysis, a voice or style guide…
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
# Writing Style Extraction Reverse-engineer a brand's verbal DNA from the copy it already publishes, and codify it so a copywriter or a generation pipeline reproduces *that* voice instead of a generic one. The core insight mirrors visual guideline extraction: a voice extracted from N texts is only as good as (a) how representative the corpus is across channels, and (b) how rigorously you separate *rules* (what the brand always does) from *variations* (what it does per channel, campaign type or language) and *exceptions* (one-offs). A brand that writes 40-character emoji-led captions and 1,500-word how-to articles has one voice and two systems — averaging them produces a voice nobody wrote. The whole workflow is built around that separation. Work through five phases in order. Phase 3's extraction fan-out is the expensive step; everything else is cheap. ## Phase 1 — Corpus inventory …

How to install
mdr add popjam-io/skills/writing-style-extraction@sha256:55ecae0a91f73510The line at the top of this page pins the label git:20261015.4d391ae, 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.
