Aws Diagrams

This turns your CloudFormation templates, AWS CLI output, or plain descriptions into architecture diagrams by calling the Eraser API directly. It parses resources like VPCs, EC2 instances, RDS databases, and Lambda functions, maps their relationships (instances in subnets, security groups attached, IAM roles), then generates Eraser DSL with AWS-specific icons. The output is minimal by design: just the diagram image, an editor link, and the code. It's built by Eraser Labs and assumes you already have AWS infrastructure you need to visualize, not that you're designing from scratch. One nice touch is it tracks which files or CLI commands it analyzed to build the diagram, so you know what went into it.

AWS Diagram Generator

Generates architecture diagrams for AWS infrastructure from CloudFormation templates, AWS CLI output, or natural language descriptions.

When to Use

Activate this skill when:

User has AWS CloudFormation templates (YAML/JSON)
User provides AWS CLI output (e.g., aws ec2 describe-instances)
User wants to visualize AWS resources
User mentions AWS services (EC2, S3, RDS, Lambda, VPC, etc.)
User asks to "diagram my AWS infrastructure"

How It Works

This skill generates AWS-specific diagrams by parsing AWS resources and calling the Eraser API directly:

Parse AWS Resources: Extract resources from CloudFormation, CLI output, or descriptions
Map AWS Relationships: Identify VPCs, subnets, security groups, IAM roles
Generate Eraser DSL: Create Eraser DSL code from AWS resources
Call Eraser API: Use /api/render/elements with diagramType: "cloud-architecture-diagram"
