Data Designer is implemented as three installable packages that share the data_designer namespace.

PackageNamespaceRole
data-designer-configdata_designer.configConfiguration schemas, builder APIs, plugin registration objects, and result schemas.
data-designer-enginedata_designer.engineRuntime extension contracts for generation, seed reading, processing, and MCP tool execution.
data-designerdata_designer.interfacePublic entry points for previewing, creating, and inspecting generated datasets.

The dependency direction is interface -> engine -> config. Config objects describe what should happen, engine objects implement how it happens, and interface objects expose the supported public API.
