Installation guide
brew install graphviz # or apt install graphviz
/plugin marketplace add mpuig/claude-cloud-diagrams
/plugin install aws-diagrams@mpuig/claude-cloud-diagramsHow to use it
Describe the AWS workflow or point at IaC/repo paths. Ask for an architecture diagram and PNG export. Iterate on boundaries and data flows.
Example prompts
- “Generate an AWS architecture diagram for this project and export it as PNG.”
- “Diagram Client → API Gateway → Lambda → DynamoDB → S3 with official-style layout.”
- “Update the diagram to show VPC, private subnets, and NAT for the worker fleet.”
Use cases and examples
- Document a Step Functions → Lambda → S3 pipeline
- Visualize multi-account landing zones for reviews
- Generate onboarding diagrams for new engineers
- Export PNG assets for RFCs and Confluence
Prerequisites
- Graphviz installed
- Claude Code plugin support or manual skill copy
- Enough architecture context (services + trust boundaries)
Tips
- Use Excalidraw for whiteboard speed; AWS Cloud Diagrams for polished infra docs.
- Pair with PlantUML for sequence diagrams of the same system.
