A tool for creating and editing draw.io diagrams, which are visual documents for systems, processes, relationships, and organizational structures. It uses structured YAML files and supports common diagram formats.

Use it for architecture diagrams, network maps, flowcharts, UML and entity-relationship diagrams, org charts, and conversions from Mermaid or CSV.

It provides a repeatable way to create, validate, import, and export diagrams instead of editing every shape by hand. It also makes the diagram source easier to maintain.

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	$0.00084	$0.03545
Opus 5	$0.00042	$0.01773

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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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/[email protected], 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.

The optional MCP/live backend is a refinement provider only. Never required for normal authoring, editing, import, replication, or export.

Task Routing

Choose the route first, then load only that route's references. All paths below live under references/; the reusable YAML example catalog is references/examples/README.md.

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.
