What this skill does

# Architecture Diagram Generator

**Quick Start:** Create HTML structure with flexible layout (single/double/triple column) → Define CSS styles for layers and grids → Add content with categorized panels → Use semantic colors for different layers.

## Critical Rules

### Rule 1: Direct HTML Embedding
**IMPORTANT**: Write architecture diagrams as direct HTML in Markdown. **NEVER** use code blocks (` ```html `). The HTML should be embedded directly in the document without any fencing.

### Rule 2: No Empty Lines in HTML Structure
**CRITICAL**: Do NOT add any empty lines within the HTML architecture diagram structure. Keep the entire HTML block continuous to prevent parsing errors.

### Rule 3: Incremental Creation Approach
**RECOMMENDED**: Create architecture diagrams in multiple steps:
1. **First**: Create the overall framework (wrapper, sidebars, main structure) and define all CSS styles
2. **Second**: Add layer containers with titles
3. **Third**: Fill in components layer by layer
4. **Fourth**: Add detailed content and refinements

### Rule 4: Flexible Layout Structure
Architecture diagrams can use flexible layouts based on complexity:
- **Single Column**: Main content only (for simple architectures)
- **Two Column**: Main content + one sidebar (left or right)
- **Three Column**: Full layout with both sidebars (for complex systems)
  - **Left Sidebar**: Supporting systems (monitoring, operations, analytics)
  - **Main Content**: Core architecture layers (user, application, data, infrastructure)
  - **Right Sidebar**: Cross-cutting concerns (security, compliance, governance)

### Rule 5: Layer-Based Organization
Each layer should have:
- Clear semantic meaning (User, Application, AI/Logic, Data, Infrastructure)
- Consistent color coding
- Grid-based layout for components
- Appropriate nesting for sub-components

### Rule 6: Color Semantics
Use consistent semantic meaning for layers — the exact color palette varies by style (see examples). The standard semantic mapping:
- **User Layer** — user-facing interfaces and clients
- **Application Layer** — business logic and API services
- **AI/Logic Layer** — intelligence, rules, processing engines
- **Data Layer** — databases, caches, storage
- **Infrastructure Layer** — containers, networking, DevOps
- **External Services** — third-party APIs, cloud services (typically dashed border)

## Layout Examples

Choose a layout structure that fits your architecture's complexity. Layouts use wireframe style (no colors) to focus on structural patterns. Combine any layout with any style above.

| # | Layout | File | Best For |
|---|---|---|---|
| 1 | **Three-Column** | [layouts/three-column.md](layouts/three-column.md) | Complex systems with cross-cutting concerns and monitoring sidebars |
| 2 | **Single Stack** | [layouts/single-stack.md](layouts/single-stack.md) | Simple services, microservice detail views, focused documentation |
| 3 | **Left Sidebar** | [layouts/left-sidebar.md](layouts/left-sidebar.md) | Systems with operations/monitoring emphasis, DevOps-centric views |
| 4 | **Right Sidebar** | [layouts/right-sidebar.md](layouts/right-sidebar.md) | Systems with security/compliance emphasis, governance-focused views |
| 5 | **Pipeline** | [layouts/pipeline.md](layouts/pipeline.md) | Data pipelines, CI/CD flows, ETL processes, horizontal stage-based flows |
| 6 | **Two-Column Split** | [layouts/two-column-split.md](layouts/two-column-split.md) | Before/after comparisons, dual-system views, migration architecture |
| 7 | **Dashboard** | [layouts/dashboard.md](layouts/dashboard.md) | System overviews with KPIs, monitoring dashboards, executive summaries |
| 8 | **Grid Catalog** | [layouts/grid-catalog.md](layouts/grid-catalog.md) | Service catalogs, component libraries, equal-weight microservices |
| 9 | **Banner + Center** | [layouts/banner-center.md](layouts/banner-center.md) | Gateway-centric architectures, user-facing systems with shared infrastructure |

## Advanced Features

**NOTE**: These advanced components require additional CSS styles. Add these to your `<style scoped>` section:

```css
.arch-product-group { display: flex; gap: 10px; }
.arch-product { flex: 1; border-radius: 8px; padding: 10px; background: rgba(255, 255, 255, 0.6); border: 1px dashed #d97706; }
.arch-product-title { font-size: 12px; font-weight: bold; color: #92400e; margin-bottom: 8px; text-align: center; }
.arch-subgroup { display: flex; gap: 8px; margin-top: 8px; }
.arch-subgroup-box { flex: 1; border-radius: 6px; padding: 8px; background: rgba(255, 255, 255, 0.5); border: 1px solid rgba(0, 0, 0, 0.08); }
.arch-subgroup-title { font-size: 10px; font-weight: bold; color: #374151; text-align: center; margin-bottom: 6px; }
.arch-user-types { display: flex; gap: 4px; justify-content: center; margin-top: 6px; }
.arch-user-tag { font-size: 9px; padding: 2px 6px; border-radius: 10px; background: rgba(59, 130, 246, 0.15); color: #1d4ed8; }
/* SVG connector lines between components */
.arch-conn { stroke: #94a3b8; stroke-width: 1.5; fill: none; }
.arch-conn-dashed { stroke: #94a3b8; stroke-width: 1.5; fill: none; stroke-dasharray: 6 4; }
.arch-conn-label { font-size: 9px; fill: #64748b; font-family: sans-serif; }
```

### Custom Product Groups
For complex applications with multiple products/modules:

```html
<div class="arch-product-group">
  <div class="arch-product">
    <div class="arch-product-title">🎯 Product A</div>
    <div class="arch-grid arch-grid-2">
      <div class="arch-box">Feature 1<br><small>Description</small></div>
