aws-diagrams

aws-diagrams is a skill for Claude Code from eraserlabs/eraser-io. It costs 27 tokens per session (2,276 once invoked), scanned A, original, MIT.

A tool that creates AWS infrastructure diagrams from CloudFormation templates, AWS command output, or written descriptions. AWS is Amazon's cloud platform, and these diagrams show its resources and connections.

In plain words
What is it for?
Use it to visualize AWS accounts or deployments, including VPCs, subnets, security groups, IAM roles, EC2, S3, RDS, and Lambda.
Why use it?
It makes cloud setups easier to understand by mapping resources such as servers, storage, databases, networks, and permissions.

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.

Security

Grade A, and why

aws-diagrams scanned grade A with 1 finding 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 11d 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.

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:

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

Instructions

When the user provides AWS infrastructure information:

  1. Parse the Source

    • CloudFormation: Extract Resources section, identify types (AWS::EC2::Instance, etc.)
    • CLI Output: Parse JSON output from aws commands
    • Description: Identify AWS service names and relationships

  2. Identify AWS Components

    • Networking: VPCs, Subnets, Internet Gateways, NAT Gateways, Route Tables
    • Compute: EC2 Instances, Auto Scaling Groups, Lambda Functions, ECS Services
    • Storage: S3 Buckets, EBS Volumes, EFS File Systems
    • Databases: RDS Instances, DynamoDB Tables, ElastiCache Clusters
    • Security: Security Groups, IAM Roles, IAM Policies, NACLs
    • Load Balancing: ALB, NLB, CLB
    • Other: SQS Queues, SNS Topics, API Gateway, CloudFront

  3. Map Relationships

    • EC2 instances in subnets
    • Subnets in VPCs
    • Security groups attached to instances
    • IAM roles attached to services
    • Load balancers targeting instances
    • Databases accessed by applications

aws-diagrams is a skill published in the GitHub repository eraserlabs/eraser-io (40 stars, last pushed 5mo ago), licensed MIT. It adds 27 tokens to every session and 2,276 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
