Ran it for real on a 3-resource Terraform snippet (Function App + Storage + Service Plan): it correctly resolved live Azure icons from the repo's own GitHub-hosted JSON index and rendered a valid SVG via `d2 --layout=elk --theme=1` - but its description advertises Bicep support while the SKILL.md's own Icon Source Requirement section only ever wires in the Terraform icon mapping URL, so a real Bicep diagram would silently fall back to plain rectangles for every single resource despite a working icon-index-bicep-png.json sitting unused in the same repo.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What D2 Diagram Generator for Azure does
Reads Terraform/Terragrunt (and, per its own description, Bicep) Azure infrastructure code and generates D2 diagram source with real Azure service icons, resource-group containers, hidden-sub-resource styling, and rule-based internet-exposure detection, then renders it via the external d2 CLI. Triggers on requests to diagram Terraform/Azure infrastructure; explicitly excludes runtime debugging and draw.io output. Requires the d2 CLI to be installed separately and is documented in its own repo README as a GitHub Copilot skill with no Claude-specific install instructions, though the SKILL.md format itself works fine when copied into a Claude skills folder.

Frequently asked questions
- Is the D2 Diagram Generator for Azure skill free?
- Yes. The skill itself is free from miiitch/d2-gen. SkillProof publishes the install command and an independent test verdict at no cost.
- Does D2 Diagram Generator for Azure work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 14, 2026. Verdict: Works with setup. Ran it for real on a 3-resource Terraform snippet (Function App + Storage + Service Plan): it correctly resolved live Azure icons from the repo's own GitHub-hosted JSON index and rendered a valid SVG via `d2 --layout=elk --theme=1` - but its description advertises Bicep support while the SKILL.md's own Icon Source Requirement section only ever wires in the Terraform icon mapping URL, so a real Bicep diagram would silently fall back to plain rectangles for every single resource despite a working icon-index-bicep-png.json sitting unused in the same repo.
