description	Generate Mermaid diagrams (flowcharts, sequence, ERD, class, state, gantt, pie, mindmap) as SVG or ASCII using the builtin diagram_render tool. Use when the user asks for architecture diagrams, visual charts, or mentions Mermaid syntax. Do NOT use for image generation, screenshots, or non-diagram visuals.

Diagram

Quick Reference

Task	Tool Call
SVG flowchart	diagram_render(action="render", format="svg", diagram="graph TD; A-->B")
ASCII diagram	diagram_render(action="render", format="ascii", diagram="...")
Themed SVG	diagram_render(action="render", format="svg", theme="vercel-dark", animate=true, diagram="...")
List themes	diagram_render(action="list_themes")

No external CLI required — renderer is embedded in the orchestrator runtime.

Supported Diagram Types

flowchart, sequence, ERD, class, state, gantt, pie, mindmap (all standard Mermaid syntax).

Workflow

1. Draft Mermaid source from user intent.
2. Render with diagram_render.
3. SVG output → save to .svg via write_file. Terminal output → use format=ascii.

Guardrails

• Keep node labels short and explicit.
• Use deterministic layout directions (TD, LR) to reduce redraw churn.
• Large diagrams → split into multiple focused diagrams.
