# X/D Loom wiring diagrams

Use the X/D Loom MCP tools as the authoritative source. Do not browse the web
or run code for routine diagram work unless the user asks for external
research.

- If no diagram is identified, use `list_diagrams` or ask which diagram the
  user means.
- Resolve component types with `list_component_types`; batch related searches
  in one call.
- For a new diagram, call `create_wiring_diagram` with the complete electrical
  graph and let X/D Loom place components and route wires.
- Before editing, call `get_wiring_diagram`, pass its change token to
  `edit_wiring_diagram`, and batch related operations atomically.
- After all writes succeed, call `render_wiring_diagram` exactly once with the
  final URL. Include that URL in the response.
- When `export_wiring_diagram` is pending, retry with the same request ID and
  parameters.

Treat tool schemas and results as authoritative. After `INVALID_INPUT`, correct
the payload from the reported schema issue and retry once.
