What is aws-architecture-diagram?

A generator for AWS architecture diagrams in draw.io format. AWS is Amazon’s cloud platform, and draw.io is a tool for creating editable diagrams of systems and how their services connect.

Use it to create editable diagrams of systems built with AWS services, including frontend entry points, data sources, supporting services, and failure paths.

It provides a defined layout for showing request flows, external systems, parallel paths, monitoring, and error handling so the architecture is easier to inspect.

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	$0.00043	$0.02864
Opus 5	$0.00022	$0.01432
Sonnet 5	$0.00009	$0.00573
Haiku 4.5	$0.00004	$0.00286

Security

Grade A, and why

aws-architecture-diagram 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 13d 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.

The opening of the file, as written. The whole thing — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Instructions

Generate a draw.io (.drawio) XML file representing an AWS architecture diagram.

Layout

Left-to-right flow for data/request path
UI/Frontend on the LEFT (users access from left side)
Data sources / external systems on the RIGHT
Use horizontal lanes for parallel paths (top lane, bottom lane)
Minimum 220px horizontal spacing between icons (to leave room for edge labels)
Minimum 250px vertical spacing between lanes (so vertical edges don't crowd)
Secondary/auxiliary services (monitoring, DLQ, error paths) go BELOW the main flow with 280px+ vertical gap

Canvas

Large canvas: pageWidth="2400" pageHeight="1400" minimum
Set dx="2800" dy="1600" for proper viewport
Always include a title block as the first element after the background:

<mxCell value="&lt;b&gt;Diagram Title&lt;/b&gt;&lt;br&gt;Author | Date | Version" style="text;html=1;align=left;verticalAlign=top;whiteSpace=wrap;rounded=0;fontSize=14;spacing=8;" vertex="1" parent="1">
  <mxGeometry x="40" y="30" width="420" height="60" as="geometry" />
</mxCell>

Icon Style

Icons are from draw.io's built-in mxgraph.aws4 stencil library — the official AWS Architecture Icons (https://aws.amazon.com/architecture/icons/, updated quarterly)
Icon size: 78x78px for main services, 65x65px for secondary
Use sketch=0 on all icons
Use strokeColor=#ffffff on all AWS service icons
Font size: 12px for labels

Edge Style — CRITICAL FOR CLEAN DIAGRAMS

Base edge style (all edges):

edgeStyle=orthogonalEdgeStyle;rounded=1;orthogonalLoop=1;jettySize=auto;html=1;strokeWidth=2;exitX=1;exitY=0.5;exitDx=0;exitDy=0;entryX=0;entryY=0.5;entryDx=0;entryDy=0;

Rules for edge labels:

Keep labels SHORT (1-2 words max). Use icon labels for detail, not edge labels.
On horizontal edges: position label ABOVE the line using verticalAlign=bottom; in the edge style
On vertical edges: position label to the LEFT using align=right; in the edge style
Always add labelBackgroundColor=#F5F5F5; so labels don't overlap lines
For edges WITHOUT labels: omit the value attribute entirely (don't use value="")

What ships with it

15 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.
