Extract design systems from reference UI images and generate implementation-ready UI design prompts. Use when users provide UI screenshots/mockups and want to create consistent designs, generate design systems, or build MVP UIs matching reference aesthetics.
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.

# UI Designer
## Overview
This skill enables systematic extraction of design systems from reference UI images through a multi-step workflow: analyze visual patterns → generate design system documentation → create PRD → produce implementation-ready UI prompts.
## When to Use
- User provides UI screenshots, mockups, or design references
- Need to extract color palettes, typography, spacing from existing designs
- Want to generate design system documentation from visual examples
- Building MVP UI that should match reference aesthetics
- Creating multiple UI variations following consistent design principles
## Workflow
### Step 1: Gather Inputs
Request from user:
- **Reference images directory**: Path to folder containing UI screenshots/mockups
- **Project idea file**: Document describing the product concept and goals
- **Existing PRD** (optional): If PRD already exists, skip Step 3
### Step 2: Extract Design System from Images
**Use Task tool with general-purpose subagent**, providing:
**Prompt template** from `assets/design-system.md`:
- Analyze color palettes (primary, secondary, accent, functional colors)
- Extract typography (font families, sizes, weights, line heights)

The line at the top of this page pins the label git:20251025.1661f91, 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.
