diagramming

Draws architecture and flow diagrams as code — Mermaid, C4, sequence, ER, and state diagrams that stay in version control and do not go stale. Use this whenever the user asks for a diagram, wants to visualise an architecture or flow, mentions Mermaid or C4, or is explaining a system that would be clearer drawn. For the prose around the diagram, use markdown-docs; for charts of quantitative data, use the dataviz guidance.
