PREFER applying/composing an existing block over redefining its members inline. Interfaces are applied with `interfaces:`; addins (types with a DefaultInstanceBrowseName) are composed with `addIns:`. A single property → use the Interface; a whole named sub-object → use the AddIn.
get_dsl_reference

Call this FIRST before writing any YAML model by hand. Works without an API key.

Use this to understand a type's structure before creating instances or subtypes.
list_namespaces

List all well-known OPC UA companion spec namespace aliases with their full names, URIs, and dependencies. Use this to discover what namespaces are available.

The AI will auto-detect relevant companion specs, generate a validated model with documentation, and auto-correct validation errors.

Returns base64-encoded artifacts if the model is valid, or diagnostics if validation fails. Optionally set include_docs=true to also generate markdown documentation.
opcua_model_reverse
