## What it does

This skill translates plain text descriptions and infrastructure manifests into native `.drawio` files. You define components in a YAML schema, and the tool builds the graph layout locally. It imports resources from Terraform, Kubernetes, or OpenAPI, as well as code imports from Go or TypeScript modules.

Running the CLI toolchain requires Node 20 or newer. Standard diagram generation is fully offline and needs no MCP server. Rendering default 300dpi PNG images relies on a local draw.io Desktop installation; without it, exports fall back to standalone SVG files.

The base package skips academic publication checks. If you need camera-ready figures for IEEE or journal papers, use the sibling `drawio-academic-skills` overlay instead.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add bahayonghang/drawio-skills --skill drawio -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bahayonghang/drawio-skills --skill drawio -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bahayonghang/drawio-skills --skill drawio -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bahayonghang/drawio-skills drawio
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add bahayonghang/drawio-skills --skill drawio -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/bahayonghang/drawio-skills --path skills/drawio
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add bahayonghang/drawio-skills --skill drawio -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/bahayonghang/drawio-skills/tree/HEAD/skills/drawio/SKILL.md

## When to use it
- Generate cloud architecture and AI agent workflows from structured YAML
- Convert Terraform, Kubernetes, or Compose configs into visual diagrams
- Transform existing Mermaid syntax and CSV tables into editable draw.io files
- Detect visual drift between infrastructure projections and live state JSON

## Example prompts
- Generate an architecture diagram for our microservices using YAML and export it as PNG
- Convert this Mermaid flowchart into a drawio file with a dark theme preset
- Map our network topology showing subnets, gateways, and VLAN boundaries

# Draw.io Base Skill

Create, edit, validate, replicate, import, and export draw.io diagrams through a YAML-first offline workflow. It is the single maintained base for sibling overlays and owns the local CLI, schemas, references, themes, palettes, examples, style presets, and export helpers.

## Scope

Use this base skill for general draw.io work: software/system architecture; network topologies and infrastructure maps; flowcharts, swimlanes, process maps, and org charts; UML class/sequence/state/ER; Mermaid and CSV conversion; structured redraw and non-academic replication; formula-bearing technical diagrams; `.drawio` import, sidecar export, and local validation.

For paper, thesis, IEEE, journal, manuscript, or publication-ready figure requests, route to the sibling `drawio-academic-skills` overlay; the base does not apply academic publication gates. Without the overlay, render the local YAML bundle but report that overlay policy was not applied.

## Runtime Stack

Use the lightest path that satisfies the request:

- **Offline Authoring Path (default)** — the YAML spec generates the final `.drawio` plus the default delivered image, a **300dpi PNG** via draw.io Desktop (standalone SVG fallback).
- **Desktop-Enhanced Export** — 300dpi PNG default, plus PDF/JPG or embedded `.drawio.svg` on explicit request.
- **Live Refinement Backend (optional)** — browser refinement provider only; the offline bundle remains canonical. Provisioned by the tracked `.mcp.json` (pinned `@next-ai-drawio/mcp-server@0.4.13`, fetched over the network by `npx`; see `references/docs/mcp-tools.md`); offline authoring never reads it.
- **Direct XML Exception** — tiny one-off or raw mxGraph handoff when exact XML control is the real requirement.
```
