Mermaid Diagrams

Turn the supplied process, code, schema, or relationships into the requested Mermaid diagram. The user's explicit instructions take precedence over this skill's guidelines, including their choice of output format.

Choose the representation

Establish the facts to show and the destination renderer. If the request leaves the format open and a text-based system/process diagram fits, Mermaid is a reasonable choice. Preserve an explicitly requested drawing tool or artifact format.

Question Diagram
What happens next or which path is taken? flowchart
Who calls whom, in what order? sequenceDiagram
What tables and cardinalities exist? erDiagram
What states and transitions exist? stateDiagram-v2
How are types or services related? classDiagram or flowchart with subgraphs
What is scheduled or measured? A matching planning/data type from the references

Use supplied evidence for nodes, edges, cardinalities, dates, and values. Mark conceptual assumptions; ask for missing facts that determine the diagram rather than inventing a system.
