Individual skill

style-fingerprint

Study 3-5 documents the user actually shipped and distil a compact style card — so every skill writes in their voice, not the model's. Use when asked to learn my writing style, make outputs sound like me, build a voice profile, or when a user complains AI drafts don't sound like them. Produces a style card (rhythm, register, structure habits, pet phrases, banned moves) saved to the Brain where every other skill reads it.

# Style Fingerprint Skill

The #1 complaint about AI drafts is "it doesn't sound like me." This skill fixes it at the root: it studies writing the user has *actually shipped*, extracts the mechanical, imitable features of their voice, and writes a style card into the Brain — after which every brain-aware skill drafts in their register instead of the model's default.

## What This Skill Produces

- A **style card** (~200-300 words, structured) capturing the user's voice as *reproducible rules*, not adjectives
- **Before/after proof**: one paragraph rewritten from model-default into the fingerprinted voice, so the user can verify the card works
- The card **saved to `brain/knowledge/style.md`** (with the user's approval), plus a one-line pointer in `context.md` voice section

## Required Inputs

Ask for (if not already provided):
- **3-5 samples the user wrote and shipped** — real emails, updates, PRD sections, posts. More samples of the *same genre* beat variety. Politely reject samples the user merely approved but didn't write — an edited-by-committee doc fingerprints the committee.
