## What it does

The skill kicks in when you ask for an AWS diagram: infrastructure, request flow, a system built from Lambda, DynamoDB, S3, API Gateway. The agent writes mxGraphModel XML, saves it to a `.drawio` file with the Write tool, then opens the result via `open` on macOS or `xdg-open` on Linux. Ask for PNG, SVG or PDF and it exports through the draw.io CLI — the XML stays embedded, so the exported file is still editable in draw.io.

Layout rules are strict. Data flows left to right, frontend sits on the left, external systems on the right, with at least 220px between icons horizontally and 250px between lanes. Auxiliary services such as monitoring drop below the main flow with a 280px gap or more. Icons come from the built-in `mxgraph.aws4` stencil library — the official AWS set — at 78x78px for main services and 65x65px for secondary ones.

3D and isometric diagrams take a different path. Those use `mxgraph.aws3d`, a legacy pre-2019 set with much smaller coverage: no API Gateway, ECS/EKS/Fargate, Step Functions, EventBridge, SNS, Aurora, CloudWatch or IAM. The skill checks a gap table and flags substitutions to you instead of guessing a stencil name. Generic hardware with no AWS icon falls back to a separate bundled isometric library. Worth checking what actually lands on the canvas before you hand the diagram to anyone else.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add vidanov/aws-architecture-diagram-skill --skill aws-architecture-diagram -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add vidanov/aws-architecture-diagram-skill --skill aws-architecture-diagram -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install vidanov/aws-architecture-diagram-skill aws-architecture-diagram
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add vidanov/aws-architecture-diagram-skill --skill aws-architecture-diagram -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/vidanov/aws-architecture-diagram-skill --path skills/aws-architecture-diagram
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add vidanov/aws-architecture-diagram-skill --skill aws-architecture-diagram -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/vidanov/aws-architecture-diagram-skill/tree/HEAD/skills/aws-architecture-diagram/SKILL.md

## When to use it
- draw an AWS diagram from Lambda, DynamoDB and API Gateway
- export a diagram to PNG or SVG while keeping it editable
- lay out services in lanes without crossing arrows
- build an isometric diagram on aws3d icons
- fix a crooked edge route between containers

## Example prompts
- Generate an AWS diagram: API Gateway, Lambda, DynamoDB, S3, left-to-right flow
- Draw our infrastructure in draw.io and export it to PNG
- Make an isometric AWS diagram with clients and on-prem servers

# AWS Architecture Diagram Skill

Generate AWS architecture diagrams as native `.drawio` files using official AWS Architecture Icons. Optionally export to PNG, SVG, or PDF with embedded XML (so exported files remain editable in draw.io).

## How to create a diagram

1. **Generate draw.io XML** in mxGraphModel format following the rules below
2. **Write the XML** to a `.drawio` file using the Write tool
3. **If the user requested an export format** (png, svg, pdf), export using the draw.io CLI (see Export section)
4. **Open the result** with `open` (macOS), `xdg-open` (Linux), or print the path

## Layout Rules

- **Left-to-right flow** for data/request path
- **UI/Frontend on the LEFT** (users access from left side)
- **Data sources / external systems on the RIGHT**
- Use horizontal lanes for parallel paths (top lane, bottom lane)
- **Minimum 220px horizontal spacing** between icons (room for edge labels)
- **Minimum 250px vertical spacing** between lanes
- Secondary/auxiliary services (monitoring, DLQ) go BELOW main flow with 280px+ gap
- Canvas: `pageWidth="2400" pageHeight="1400"`, viewport `dx="2800" dy="1600"`
- Always include a title block after the background rectangle:
```xml
<mxCell value="&lt;b&gt;Diagram Title&lt;/b&gt;&lt;br&gt;Author | Date | Version" style="text;html=1;align=left;verticalAlign=top;whiteSpace=wrap;rounded=0;fontSize=14;spacing=8;" vertex="1" parent="1">
  <mxGeometry x="40" y="30" width="420" height="60" as="geometry" />
</mxCell>
```

## Icon Style

- Icons are from draw.io's built-in `mxgraph.aws4` stencil library — the **official AWS Architecture Icons** (https://aws.amazon.com/architecture/icons/)
- Icon size: **78x78px** for main services, **65x65px** for secondary
- Use `sketch=0` on all icons
