# QuartzUIValidateCommandlet: declaration reference

> **0.57.0-dev · beta source documentation.** Native, Blueprint, Editor and rendering examples are source-reviewed, not executed in Unreal during this scan. See [validation and limits](https://betterbuilt.games/docs/quartz-ui/evidence).

Pinned source (source: `Source/QuartzUIEditor/Public/QuartzUIValidateCommandlet.h`) · [integration recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuivalidatecommandlet) · [practical guide](https://betterbuilt.games/docs/quartz-ui/tools-shipping)

## UQuartzUIValidateCommandlet

**Editor type.** Headless project/settings/output audit used by CI and the automatic cook hook.

**Prerequisites / integration:** Installed source plugin; Editor tools additionally require a compiled compatible host Editor target. Use the [QuartzUIValidateCommandlet recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuivalidatecommandlet) in the host module `QuartzUIEditor`.

**Minimal example / lifecycle:** UnrealEditor-Cmd Host.uproject -run=QuartzUIValidate -Mode=Shipping. One commandlet invocation; evidence written to selected paths.

**Avoid:** Claiming a green audit proves GPU or gameplay behavior. Match the exact declaration below; dependent DTOs/enums are values used by this owner, not independent systems.

Exact source line (source: `Source/QuartzUIEditor/Public/QuartzUIValidateCommandlet.h#L9`)

## Complete header

Source snapshot, not an additional example. Unreal annotations distinguish exposed Blueprint nodes from native-only/private methods.
