# Type Alias: CommandNodeDesc

> **CommandNodeDesc** = `object`

Defined in: [packages/webgpu/src/types.ts:839](https://github.com/uinosoft/zenfg/blob/327c05c78d2f528e4f4a679fcc7a77d9aa161f48/packages/webgpu/src/types.ts#L839)

Declares caller-defined commands in a FrameGraph-owned command segment.

Command nodes default to a side effect because their commands are opaque to
dependency analysis.
