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.

Security

Grade B, and why

drawio scanned grade B with 1 finding 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 16d 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.

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

  1. Generate draw.io XML in mxGraphModel format for the requested diagram
  2. Write the XML to a .drawio file in the current working directory using the Write tool
  3. 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
  4. 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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
