```

- text schema: Stores schema as text.
- int schemaVersion: Stores schema version as int.
- text provider: Stores provider as text.
- bool accessibility: Stores accessibility as bool.
- bool textInput: Stores text input as bool.
- bool clipboard: Stores clipboard as bool.
- bool displayTopology: Stores display topology as bool.
- bool sessionLifecycle: Stores session lifecycle as bool.
- bool virtualKeyboard: Stores virtual keyboard as bool.
- bool delayedClipboard: Stores delayed clipboard as bool.
- text threadModel: Stores thread model as text.
- text unavailablePolicy: Stores unavailable policy as text.
- nativeUiHostCapabilityRecord(text provider, bool accessibility, bool textInput, bool clipboard, bool displayTopology, bool sessionLifecycle, bool virtualKeyboard, bool delayedClipboard): Native ui host capability record.
- Describe() returns text: Describe.

## Use nativeUiHostCapabilityRecord

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using host.ui_services

// Define host text, editing, clipboard, and accessibility service contracts.
nativeUiHostCapabilityRecord sample = nativeUiHostCapabilityRecord("provider", true, true, true, true, true, true, true)
Console.Log(Text.From(sample.schema))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.host_ui_services__nativeuihostcapabilityrecord"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/host.ui_services--nativeUiHostCapabilityRecord/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## nativeUiHostCapabilityRecord.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using host.ui_services

// Describe.
nativeUiHostCapabilityRecord instance = nativeUiHostCapabilityRecord("provider", true, true, true, true, true, true, true)
text result = instance.Describe()
Console.Log(Text.From(result))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.host_ui_services__nativeuihostcapabilityrecord"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/host.ui_services--nativeUiHostCapabilityRecord/method-Describe-13 --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
