Terraform Diagrams

Turns your Terraform files into visual architecture diagrams by parsing resources, modules, and dependencies, then hitting the Eraser API to render them. It understands multi-cloud setups across AWS, Azure, and GCP, groups resources by VPCs or VNets, and maps out the connections between load balancers, instances, databases, and everything else defined in your HCL. The output is tight: just the diagram image, an editor link, and the DSL code. Useful when you inherit infrastructure code and need to see what's actually deployed, or when you want to document your setup without drawing boxes manually. Works best when you have real .tf files to feed it.

Terraform Diagram Generator

Generates architecture diagrams directly from Terraform .tf files. Specializes in parsing Terraform code and visualizing infrastructure resources, modules, and their relationships.

When to Use

Activate this skill when:

User has Terraform files (.tf, .tfvars) and wants to visualize the infrastructure
User asks to "diagram my Terraform" or "visualize this infrastructure"
User mentions Terraform, HCL, or infrastructure-as-code
User wants to see the architecture of their Terraform-managed resources

How It Works

This skill generates Terraform-specific diagrams by parsing Terraform code and calling the Eraser API directly:

Parse Terraform Files: Identify resources, modules, data sources, and variables
Extract Relationships: Map dependencies, resource connections, and module hierarchies
Generate Eraser DSL: Create Eraser DSL code from Terraform resources
Call Eraser API: Use /api/render/elements with diagramType: "cloud-architecture-diagram"
