list-diagram-types

List Diagram Types

Display all available diagram-type presets. Diagram types guide the model's layout and rendering approach (e.g., network topology, flowchart, Kubernetes cluster, mind-map, data pipeline, entity-relationship, etc.).

When to use

• User wants to see diagram-type options before describing their diagram
• User is unsure what diagram types are available
• User wants to specify a diagram type when calling generate-tech-diagram

Inputs to gather

None — this is a read-only reference skill.

Procedure

1. If the MCP is not installed, show the user: claude mcp add nano-tech-diagrams -- npx -y nano-tech-diagrams-mcp and stop.
2. Call mcp__nano-tech-diagrams__list_diagram_types at runtime to fetch the current list.
3. Parse the response. If the MCP returns categories or groupings, format as categorised markdown or table.
4. Include brief descriptions or use-case examples for each type if available from the MCP.
5. Display the list to the user.

Output / side effects

• User sees a formatted list of available diagram types.
• No files created or modified.

Safety / constraints

• Never hard-code the diagram-type list — always call the MCP to ensure the list is current.
• If the MCP is unavailable, provide a graceful error and the installation command.
