Implementation Reference
- src/airflow/dag.py:114-117 (handler)The handler function that implements the unpause_dag tool. It creates a DAG object with is_paused=False and patches the DAG using the Airflow API.
async def unpause_dag(dag_id: str) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: dag = DAG(is_paused=False) response = dag_api.patch_dag(dag_id=dag_id, dag=dag, update_mask=["is_paused"]) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/dag.py:15-33 (registration)The get_all_functions function registers the unpause_dag tool (and others) by returning a tuple (unpause_dag, "unpause_dag", "Unpause a DAG by ID", False).
