## What it does

The skill reads the project README and codebase to generate a single `[project]-architecture.html` report. It structures information into six distinct sections: business context, data flow, processing pipeline, system architecture layers, feature requirements, and deployment details.

Visual flow charts are rendered directly via inline SVG elements. It applies fixed semantic colors to distinguish components: `#4299e1` for data sources, `#ed8936` for processing stages, `#9f7aea` for AI modules, and `#48bb78` for outputs.

The resulting file relies on basic HTML and inline styles. Because everything lives in one file, you can open and share the diagram without spinning up external services.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mhattingpete/claude-skills-marketplace --skill architecture-diagram-creator -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mhattingpete/claude-skills-marketplace --skill architecture-diagram-creator -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mhattingpete/claude-skills-marketplace --skill architecture-diagram-creator -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mhattingpete/claude-skills-marketplace architecture-diagram-creator
```

2. **Manually: put the files in place**
- File: `.github/skills/architecture-diagram-creator/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mhattingpete/claude-skills-marketplace --skill architecture-diagram-creator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mhattingpete/claude-skills-marketplace --path visual-documentation-plugin/skills/architecture-diagram-creator
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mhattingpete/claude-skills-marketplace --skill architecture-diagram-creator -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/mhattingpete/claude-skills-marketplace/tree/HEAD/visual-documentation-plugin/skills/architecture-diagram-creator/SKILL.md

## When to use it
- document system architecture for an existing codebase
- generate SVG data flow diagrams from sources to outputs
- visualize multi-stage processing pipelines
- compile deployment prerequisites and business goals into one file

## Example prompts
- Create architecture diagram for this project
- Generate high-level overview and document system architecture
- Show data flow and processing pipeline in HTML

# Architecture Diagram Creator

Create comprehensive HTML architecture diagrams with data flows, business context, and system architecture.

## When to Use

- "Create architecture diagram for [project]"
- "Generate high-level overview"
- "Document system architecture"
- "Show data flow and processing pipeline"

## Components to Include

1. **Business Context**: objectives, users, value, metrics
2. **Data Flow**: sources → processing → outputs with SVG diagram
3. **Processing Pipeline**: multi-stage visualization
4. **System Architecture**: layered components (data/processing/services/output)
5. **Features**: functional and non-functional requirements
6. **Deployment**: model, prerequisites, workflows

## HTML Structure

```html
<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>[Project] Architecture</title>
  <style>
    body { font-family: system-ui; max-width: 1200px; margin: 0 auto; padding: 20px; }
    h1 { background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); color: white; padding: 30px; }
    .section { margin: 30px 0; }
    svg { max-width: 100%; }
    /* Use semantic colors: #4299e1 (data), #ed8936 (processing), #9f7aea (AI), #48bb78 (success) */
  </style>
</head>
<body>
  <h1>[Project Name] - Architecture Overview</h1>

  <!-- Business Context Section -->
  <!-- Data Flow Diagram (SVG) -->
  <!-- Processing Pipeline (SVG) -->
  <!-- System Architecture Layers -->
  <!-- Features Grid -->
  <!-- Deployment Info -->
</body>
</html>
```

## SVG Pattern for Data Flow

```html
<svg viewBox="0 0 800 400">
  <!-- Data sources (left, blue) -->
  <rect x="50" y="150" width="120" height="80" fill="#4299e1"/>

  <!-- Processing (center, orange) -->
  <rect x="340" y="150" width="120" height="80" fill="#ed8936"/>

  <!-- Outputs (right, green) -->
  <rect x="630" y="150" width="120" height="80" fill="#48bb78"/>

  <!-- Arrows connecting -->
  <path d="M170,190 L340,190" stroke="#666" stroke-width="2" marker-end="url(#arrow)"/>
</svg>
```

## Workflow

1. Analyze project (README, code structure)
2. Extract: purpose, data sources, processing, tech stack, outputs
3. Create HTML with all 6 sections
4. Use semantic colors for visual hierarchy
