What is aws-architecture-diagram?

A tool for creating editable AWS architecture diagrams in draw.io, a diagramming application, using official AWS service icons. AWS is Amazon’s cloud platform, with services such as Lambda, S3, and DynamoDB.

Use it to create AWS infrastructure or system diagrams and export them as draw.io files, PNG images, SVG graphics, or PDFs.

It gives cloud systems a consistent visual layout that shows how users, services, data, and supporting systems connect. The diagrams remain editable instead of being only flattened images.

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	$0.00057	$0.04838
Opus 5	$0.00028	$0.02419

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 12d 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.

AWS Architecture Diagram Skill

Generate AWS architecture diagrams as native .drawio files using official AWS Architecture Icons. Optionally export to PNG, SVG, or PDF with embedded XML (so exported files remain editable in draw.io).

How to create a diagram

Generate draw.io XML in mxGraphModel format following the rules below
Write the XML to a .drawio file using the Write tool
If the user requested an export format (png, svg, pdf), export using the draw.io CLI (see Export section)
Open the result with open (macOS), xdg-open (Linux), or print the path

Layout Rules

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 (room for edge labels)
Minimum 250px vertical spacing between lanes
Secondary/auxiliary services (monitoring, DLQ) go BELOW main flow with 280px+ gap
Canvas: pageWidth="2400" pageHeight="1400", viewport dx="2800" dy="1600"
Always include a title block after the background rectangle:

<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/)
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
NO colored backgrounds on group boxes — always fillColor=none

3D / Isometric Diagrams — use a different icon library

If the user asks for a 3D, isometric, or "AWS 3D" diagram, do NOT fake it by placing flat aws4 icons on hand-built platform/pedestal shapes. draw.io has a real, separate built-in library for this: mxgraph.aws3d.*.

Load references/aws-icons-3d.md before picking any icon — it has the verified shape table, style prefix, sizes, and the native isometricEdgeStyle edge templates.
This library is a legacy pre-2019 icon set with much smaller coverage than aws4 (no API Gateway, ECS/EKS/Fargate, Step Functions, EventBridge, SNS, Aurora, CloudWatch, IAM, etc.). Check the gap table in that reference file before assuming an icon exists, and flag substitutions to the user rather than guessing a stencil name.
For generic hardware (clients, on-prem servers, racks, switches) with no AWS-specific icon, see references/aws-icons-allied-telesis.md — a separate bundled isometric image library that fills that gap.
These icons are already 3D on their own — arrange them in an ascending isometric staircase (diagonal offsets between nodes), don't add fake platforms underneath.
Use edgeStyle=isometricEdgeStyle (with endArrow=block override for reliable arrowheads) instead of orthogonalEdgeStyle for connectors.
