Reverse-engineer a comprehensive brand style guide from a corpus of existing design assets (social posts, ad creatives, banners, decks, videos). Produces a structured guideline document plus a reusable "style prompt block" for on-brand AI image generation. Use this whenever the user wants brand guidelines, a style guide, design-language or "look and feel" analysis, brand DNA extraction, visual identity documentation, or wants AI-generated images to match an existing brand — even if they just…
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
# Brand Guideline Extraction
Reverse-engineer a brand's visual and verbal DNA from existing design assets, and codify it so a human designer or a generative pipeline can reproduce the look and feel.
The core insight: a brand guideline extracted from N assets is only as good as (a) how representative the corpus is, and (b) how rigorously you separate *rules* (what the brand always does) from *variations* (what it sometimes does) and *exceptions* (one-offs). The whole workflow is built around that separation.
Work through five phases in order. Phases 2's subagent fan-out is the expensive step; everything else is cheap.
## Phase 1 — Asset inventory
Locate the assets. Usually the user provides a folder; if they name external sources (Meta Ad Library, a website, social profiles) gather what's accessible first, but never block on missing sources — work with what exists and note coverage gaps in the final document.
Build `work/inventory.json`, one entry per asset:
```json
{"file": "path", "kind": "image|video|source_file", "width": 1080, "height": 1920,
"format_class": "square|portrait|story|landscape", "content_type": "best guess: product-ad|announcement|seasonal|job-ad|...",

How to install
mdr add popjam-io/skills/brand-guideline-extraction@sha256:c68babca2771aa3aThe 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.
