What is d2-gen-azure?

A generator that turns Azure infrastructure code—Terraform, Terragrunt, or Bicep files—into D2 architecture diagram source.

Use it to create and format .d2 diagrams and render them as SVG or PNG files for Azure infrastructure.

It makes resource relationships, networks, permissions, monitoring, and data flows easier to inspect visually.

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	$0.00121	$0.01886
Opus 5.5	$0.00048	$0.00754
Sonnet 5.5	$0.00024	$0.00377
Haiku 4.5	$0.00012	$0.00189

Security

Grade A, and why

d2-gen-azure 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 2mo 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.

D2 Diagram Generator

When to Use

Generate architecture diagrams from Terraform or Terragrunt code
Visualize Azure infrastructure with proper icons, connections, and grouping
Create .d2 files rendered to SVG/PNG via the d2 CLI
Represent resource dependencies, network topology, RBAC, monitoring, and data flows

Goal

Create readable architecture diagrams using D2 language for Azure/Terraform infrastructure. Output is .d2 text files, rendered to SVG or PNG via the d2 CLI.

Tools

d2 CLI: Render .d2 files to SVG/PNG: d2 input.d2 output.svg
d2 CLI with layout engine: d2 --layout=elk input.d2 output.svg
d2 fmt: Format D2 files: d2 fmt input.d2
No MCP server is used — the skill generates D2 source code as text.

Icon Source Requirement

Use this Terraform icon mapping as the source of truth:

Mapping index: https://raw.githubusercontent.com/miiitch/d2-gen/refs/heads/main/icon-index-terraform-png.json
Base path for icon files: https://raw.githubusercontent.com/miiitch/d2-gen/refs/heads/main

Resolution rule:

Look up the Terraform resource type key (e.g. azurerm_linux_function_app) in the mapping JSON.
The mapped value is a relative path (e.g. png/Icons/iot/10029-icon-service-Function-Apps.png).
Build the final icon URL: base path + / + relative path.
In generated .d2 files, reference the full URL directly in icon:.

Fallback: if no mapping entry exists, use shape: rectangle with a clear text label.

Recommended Workflow

Read Terraform/Terragrunt files and list all resources + dependencies.
Analyze sub-resources for each parent and classify as hidden (from registry) or explicit.
Ask the mandatory Yes/No questionnaire before generating connections or containers (must be asked every time).
Determine the resource hierarchy before placing nodes.
Build workload-centric clusters first (workload at center, required resources around it).
Apply the Hidden Sub-Resources Registry: hide listed sub-resources and represent them as styled connections to the parent resource.
Resolve icon URLs from the mapping index, then generate the .d2 file with containers, nodes, connections, icons, and styles.
Validate D2 syntax with d2 fmt before sharing.
Render with d2 --layout=elk input.d2 output.svg and verify output.
If the user wants an autonomous SVG, download mapped icons locally and render a bundled SVG.
When regenerating an existing diagram, re-resolve icon URLs from the mapping file (and re-download only used icons for autonomous output if needed).

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.
