## What it is
A Go-based CLI tool (awsdac) that generates AWS architecture diagrams from human-readable YAML definitions, following AWS diagram guidelines. It can also convert CloudFormation templates into diagrams and be used as a Go library for integration with IaC tools and AI assistants.

## Use cases
- generate AWS architecture diagrams from YAML code
- convert CloudFormation templates into architecture diagrams
- manage infrastructure diagrams in Git as code
- automate diagram generation in CI/CD pipelines
- create diagrams compliant with AWS architecture icon guidelines
- integrate diagram generation with AI assistants via MCP server

## When to choose
- you want diagrams-as-code versioned with Git instead of manual drawing tools
- your infrastructure is on AWS and you want guideline-compliant diagrams
- you need lightweight, headless diagram generation in CI/CD pipelines
- you want to derive diagrams automatically from CloudFormation templates

## When to avoid
- you need diagrams for non-cloud or multi-cloud architectures without writing custom definition files
- you need interactive, drag-and-drop diagram editing
- you require rich output formats beyond PNG or complex custom styling
