A skill for creating editable draw.io diagrams as native .drawio files. Draw.io is a diagram editor used for flowcharts, architecture drawings, and other visual plans, and files can optionally be exported to PNG, SVG, or PDF.

Use it to create flowcharts, system diagrams, entity-relationship diagrams, or other diagrams in the requested format.

It converts a written diagram request into a file that can be opened and edited in draw.io, with optional shareable exports.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.01656
Opus 5	$0.00012	$0.00828
Sonnet 5	$0.00005	$0.00331
Haiku 4.5	$0.00002	$0.00166

Security

Grade A, and why

drawio scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Draw.io Diagram Skill

Generate draw.io diagrams as native .drawio files. Optionally export to PNG, SVG, or PDF with the diagram XML embedded (so the exported file remains editable in draw.io).

How to create a diagram

Generate draw.io XML in mxGraphModel format for the requested diagram
Write the XML to a .drawio file in the current working directory using the Write tool
If the user requested an export format (png, svg, pdf), export using the draw.io CLI with --embed-diagram, then delete the source .drawio file
Open the result — the exported file if exported, or the .drawio file otherwise

Choosing the output format

Check the user's request for a format preference. Examples:

/drawio create a flowchart → flowchart.drawio
/drawio png flowchart for login → login-flow.drawio.png
/drawio svg: ER diagram → er-diagram.drawio.svg
/drawio pdf architecture overview → architecture-overview.drawio.pdf

If no format is mentioned, just write the .drawio file and open it in draw.io. The user can always ask to export later.

Supported export formats

Format	Embed XML	Notes
`png`	Yes (`-e`)	Viewable everywhere, editable in draw.io
`svg`	Yes (`-e`)	Scalable, editable in draw.io
`pdf`	Yes (`-e`)	Printable, editable in draw.io
`jpg`	No	Lossy, no embedded XML support

PNG, SVG, and PDF all support --embed-diagram — the exported file contains the full diagram XML, so opening it in draw.io recovers the editable diagram.

draw.io CLI

The draw.io desktop app includes a command-line interface for exporting.

Locating the CLI

Try drawio first (works if on PATH), then fall back to the platform-specific path:

macOS: /Applications/draw.io.app/Contents/MacOS/draw.io
Linux: drawio (typically on PATH via snap/apt/flatpak)
Windows: "C:\Program Files\draw.io\draw.io.exe"

Use which drawio (or where drawio on Windows) to check if it's on PATH before falling back.

drawio is a skill published in the GitHub repository LiYu0524/Auto-Reasearch-Skills (11 stars, last pushed 6mo ago), licensed MIT. It adds 24 tokens to every session and 1,656 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
