        Retrieves the specified agent.

        Example:
            >>> import dialogflow_v2
            >>>
            >>> client = dialogflow_v2.AgentsClient()
            >>>
            >>> parent = client.project_path('[PROJECT]')
            >>>
            >>> response = client.get_agent(parent)

        Args:
            parent (str): Required. The project that the agent to fetch is associated with.
                Format: ``projects/<Project ID>``.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.cloud.dialogflow_v2.types.Agent` instance.

        Raises:
            google.api_core.exceptions.GoogleAPICallError: If the request
                    failed for any reason.
            google.api_core.exceptions.RetryError: If the request failed due
                    to a retryable error and retry attempts failed.
            ValueError: If the parameters are invalid.
