What it does
Drawio is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Generate draw.io diagrams as .drawio files and export to PNG/SVG/PDF with embedded XML
Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/package.json`).
It sits in Development, covering Diagrams. It works with draw.io. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.
When your agent uses it
- Tasks that involve Diagrams
Example prompts
- “/drawio”
Requirements
- Node.js
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Generate draw.io XML in mxGraphModel format for the requested diagram
- Write the XML to a .drawio file using the create/edit file tool
- Export to PNG using the bundled export script
What it can do on your machine
Read from SKILL.md and the folder at commit 727ff2e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
nodenpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Drawio loads about 805 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 200 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Draw.io Diagram Skill
Generate draw.io diagrams as native .drawio files and export them to PNG images that can be embedded in Word documents.
How to Create a Diagram
- Generate draw.io XML in
mxGraphModelformat for the requested diagram - Write the XML to a
.drawiofile using the create/edit file tool - Export to PNG using the bundled export script
Bundled Export Script
This skill includes drawio-to-png.mjs, a Node.js export script with two rendering backends:
- draw.io CLI (pixel-perfect, fastest) — used automatically if draw.io desktop is installed
- Official draw.io viewer in headless browser (pixel-perfect, needs Chromium/Edge) — fallback when CLI is unavailable
Usage
# Install dependencies (one-time, from the scripts folder)
cd skills/drawio/scripts && npm install
# Export a single diagram
node skills/drawio/scripts/drawio-to-png.mjs <input.drawio> [output.png]
# Export all .drawio files in a directory
node skills/drawio/scripts/drawio-to-png.mjs --dir <directory>
# Force a specific renderer

Draw.io XML Style Conventions
Use these styles for consistent, professional diagrams:
<!-- Primary service (highlighted) -->
<mxCell style="rounded=1;whiteSpace=wrap;html=1;fillColor=#dae8fc;strokeColor=#6c8ebf;strokeWidth=2;arcSize=12;shadow=1;" />
<!-- External system -->
<mxCell style="rounded=1;whiteSpace=wrap;html=1;fillColor=#f5f5f5;strokeColor=#666666;" />
<!-- Success/processing stage -->
<mxCell style="rounded=1;whiteSpace=wrap;html=1;fillColor=#d5e8d4;strokeColor=#82b366;" />
<!-- Warning/quality gate -->
<mxCell style="rounded=1;whiteSpace=wrap;html=1;fillColor=#fff2cc;strokeColor=#d6b656;" />
<!-- Error/failure path -->
<mxCell style="rounded=1;whiteSpace=wrap;html=1;fillColor=#f8cecc;strokeColor=#b85450;" />
<!-- Data store (cylinder) -->
<mxCell style="shape=cylinder3;whiteSpace=wrap;html=1;fillColor=#fff2cc;strokeColor=#d6b656;" />
<!-- Arrow -->
<mxCell style="edgeStyle=orthogonalEdgeStyle;rounded=1;strokeColor=#6c8ebf;strokeWidth=2;" />Locating the draw.io CLI
Try drawio first (works if on PATH), then fall back:
- Windows:
"C:\Program Files\draw.io\draw.io.exe" - macOS:
/Applications/draw.io.app/Contents/MacOS/draw.io - Linux:
drawio(via snap/apt/flatpak)
CLI Export Command
drawio -x -f png -e -b 10 -o <output.png> <input.drawio>Flags: -x (export), -f (format), -e (embed diagram XML), -b (border), -o (output path).

Can I use Drawio in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add github/awesome-copilot --skill drawio -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/drawio, .gemini/skills/drawio, .github/skills/drawio and .opencode/skills/drawio in your project.
What does Drawio need to run?
Going by SKILL.md and its folder, Drawio needs JavaScript for the scripts in its folder and the command-line tools its instructions call (node and npm). Our summary lists: Node.js.
Does Drawio access the network?
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Drawio safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Drawio use?
Drawio is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Drawio use?
About 805 tokens (SKILL.md is roughly 3.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
