A skill for creating draw.io diagrams, including cloud architectures and business processes. Draw.io is a diagram format and editor; cloud architecture shows how hosted computing services connect, while a business-process diagram shows steps and roles.

It helps make diagrams for AWS, Azure, Google Cloud, Databricks, networks, data pipelines, serverless systems, and role-based workflows such as BPMN or swimlanes.

It turns a described system or workflow into a structured diagram with placed boxes, connected arrows, and checks for a valid result.

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	$0.00102	$0.01444
Opus 5.5	$0.00041	$0.00578
Sonnet 5.5	$0.00020	$0.00289
Haiku 4.5	$0.00010	$0.00144

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 3d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

draw.io diagrams

You build the diagram by writing a small Node script that uses the drawio-ai engine. The engine places every box and routes every arrow. You only declare what is inside what.

Follow the steps in order. Do not skip a step. Each step names the exact file to read — read only that file, nothing else in the kit.

Step 0 — Check the CLI

command -v drawio-ai >/dev/null 2>&1 && drawio-ai root || echo "MISSING"

If it prints MISSING: stop. Tell the user to install it, then try again:

npm i -g drawio-ai-kit

Never run npm i -g yourself.

Step 1 — Understand the request

You need these 4 facts. Take them from the user's message first.

Fact	Example	If missing
Domain	AWS · Azure · GCP · Databricks · multi-cloud · BPMN	Ask.
What to draw	"3-tier web app in one VPC, 2 AZs" · "order approval process"	Ask.
Output path	`./docs/arch.drawio`	Use `<cwd>/<short-name>.drawio`. Do not ask. The build script goes in the same folder.
Format	`.drawio` (default) · also `.png`	Use `.drawio`. Do not ask.

Rules for asking:

Ask one short message with all missing questions together. Offer choices, e.g. "Which cloud: AWS, Azure, or GCP?"
If the user said "just do it" or the request is already clear, do not ask. Pick the common choice and tell the user what you assumed at the end.
The source is a Terraform/Terramate repo? Follow workflows/from-iac.md before Step 2.

Step 2 — Pick the domain reference

Read exactly one row's files from this skill folder:

Domain	Read	Template to start from (`drawio-ai scaffold --list` shows all)
AWS	`references/aws-architecture.md`	`build_vpc.mjs`, `build_serverless.mjs`, `build_pipeline.mjs`, `build_landingzone.mjs`
Azure	`references/azure-architecture.md`	`build_azure_vnet.mjs`, `build_azure_hub_spoke_lz.mjs`
GCP	`references/gcp-architecture.md`	`build_gcp_vpc.mjs`, `build_gcp_shared_vpc_landing_zone.mjs`
Databricks	`references/databricks-architecture.md`	`build_lakehouse.mjs`, `build_data_platform.mjs`
Multi-cloud / hybrid	the reference of each cloud involved	`build_multicloud.mjs`, `build_hybrid.mjs`
BPMN / swimlane	`references/bpmn.md`	`build_bpmn.mjs`

What ships with it

12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

drawio is a skill published in the GitHub repository sparklabx/drawio-ai-kit (657 stars, last pushed 4d ago), licensed MIT. It adds 102 tokens to every session and 1,444 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-13.
