# diagrams
Architecture and software design diagrams as Mermaid: C4 context and container, infrastructure and deployment (including AWS, Azure, and Google Cloud architecture diagrams with provider icons), sequence, flowchart, state, entity relationship, and class. Picks the diagram for the audience, derives content from the codebase, renders with mermaid-cli to verify, and hands off to draw.io when an editable file is required.

## What diagrams does, in the publisher's words

An agent plugin that produces architecture and software design diagrams as Mermaid, verified by rendering them.

- One skill, every architecture view: C4 system context and container, infrastructure and deployment, AWS, Azure, and Google Cloud architecture with provider icons, sequence, flowchart, state, entity relationship, and class diagrams. Diagram types are reference files loaded on demand, not separate skills, so one request loads one skill.
- Audience first: the skill pins down the question a diagram answers and who reads it before choosing a type or an abstraction level, and splits when one picture is trying to answer two questions.
- Facts from the code: every node and edge traces to a file (routes, clients, infrastructure as code, migrations, schemas) or is marked as proposed. Nothing is invented to make a picture look complete.
