# ExecutionContext.runner_context

```python theme={"system"}
ExecutionContext.runner_context: RunnerContext
```

Access the runner context instance for the runner executing the task.

Use a custom `RunnerContext` subclass when tasks need shared runtime configuration or helpers during execution.

## Returns

The runner context object associated with the runner.

```python Python theme={"system"}
def execute(self, context: ExecutionContext) -> None:
    bucket = context.runner_context.gcs_client("my-project:my-bucket")
    blob = bucket.blob("inputs/scene.json")
    data = blob.download_as_bytes()
```
