Engine Extension API | NVIDIA NeMo Data Designer

The data-designer-engine package provides the runtime layer of Data Designer. It consumes data_designer.config objects and maps them to execution behavior through generators, seed readers, processors, registries, model access, and MCP tool execution.

This section is intentionally curated. Use it for plugin implementation contracts, registry behavior, seed reader internals, processor execution, column generator bases, and MCP runtime behavior. It does not expose every internal engine module.
