## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'luma_post_v1_calendars_event_tags_apply',
  {
    "tag": "example",
    "event_ids": [
      "event_123"
    ]
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute luma_post_v1_calendars_event_tags_apply --input '{
  "tag": "example",
  "event_ids": [
    "event_123"
  ]
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "data": {
    "applied_count": 123,
    "skipped_count": 123
  }
}
```

Use `deepline describe luma_post_v1_calendars_event_tags_apply --json` for the latest machine-readable contract.
