writing-style-extraction skillA

writing-style-extraction is agent-read markdown (skill) from popjam-io/skills: 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, "make copy sound like us",.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
