## What it does

The skill studies UI references for colour palettes, typography, spacing, and component styles such as buttons, cards, inputs, and icons. It can capture dark-mode variants, motion patterns, and component states, then writes the design system to `documents/designs/`.

It uses a product-idea file with `assets/app-overview-generator.md` to create or refine a PRD through user discussion. `assets/vibe-design-template.md` combines that PRD with the visual rules and saves an implementation prompt in `documents/ux-design/`.

Before implementation, it checks for a React project. If one is missing, the skill suggests creating it and adding Tailwind CSS, PostCSS, Autoprefixer, and `lucide-react`. You need reference images and a project-idea file before the workflow can begin, so prepare both first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill ui-designer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ui-designer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ui-designer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill ui-designer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ui-designer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill ui-designer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ui-designer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install daymade/claude-code-skills ui-designer
```

2. **Manually: put the files in place**
- File: `.github/skills/ui-designer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill ui-designer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/daymade/claude-code-skills --path ui-designer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ui-designer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill ui-designer -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/daymade/claude-code-skills/tree/HEAD/ui-designer/SKILL.md

## When to use it
- extract a colour palette from UI screenshots
- document typography and component styling
- turn a product idea into a PRD
- compose a React UI implementation prompt
- keep design outputs in `documents/`

## Example prompts
- Analyse my UI screenshots, extract a design system, and save it in `documents/designs/`.
- Use my product idea file to refine a PRD, then combine it with the design system.
- Check the React project and implement the UI from the prompt in `documents/ux-design/`.

# 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)
- Identify component styles (buttons, cards, inputs, icons)
- Document spacing system
- Note animations/transitions patterns
- Include dark mode variants if present

**Attach reference images** to the subagent context.

**Output**: Complete design system markdown following the template format

**Save to**: `documents/designs/{image_dir_name}_design_system.md`

### Step 3: Generate MVP PRD (if not provided)

**Use Task tool with general-purpose subagent**, providing:

**Prompt template** from `assets/app-overview-generator.md`:
- Replace `{项目背景}` with content from project idea file
- The template guides through: elevator pitch, problem statement, target audience, USP, features list, UX/UI considerations

**Interact with user** to refine and clarify product requirements

**Output**: Structured PRD markdown

**Save as variable** for Step 4 (optionally save to `documents/prd/`)

### Step 4: Compose Final UI Implementation Prompt

Combine design system and PRD using `assets/vibe-design-template.md`:

**Substitutions:**
- `{项目设计指南}` → Design system from Step 2
- `{项目MVP PRD}` → PRD from Step 3 or provided PRD file

**Result**: Complete, implementation-ready prompt containing:
- Design aesthetics principles
- Project-specific color/typography guidelines
- App overview and feature requirements
- Implementation tasks (multiple UI variations, component structure)
```
