+# Mermaid Generate
+
+Create a Mermaid diagram based on user description through multi-turn conversation until the complete details are understood.
+
+## Process
+
+1. **Understand the ask** — Clarify what needs to be visualized
+2. **Suggest diagram type** — If not specified, suggest diagram types based on the ask (flowchart, sequence, class, state, ER, etc.)
+3. **Generate** — Create the diagram strictly following Mermaid syntax and CommonMark fenced code block standards
+4. **Iterate** — Refine based on user feedback
+
+## Output
+
+A Mermaid diagram in a fenced code block, ready to render.
