Implementation Reference
- src/airflow/pool.py:23-50 (handler)The handler function for the 'get_pools' tool. It accepts optional parameters for limit, offset, and order_by, calls the Airflow PoolApi to retrieve pools, and returns the response as text content.
async def get_pools( limit: Optional[int] = None, offset: Optional[int] = None, order_by: Optional[str] = None, ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: """ List pools. Args: limit: The numbers of items to return. offset: The number of items to skip before starting to collect the result set. order_by: The name of the field to order the results by. Prefix a field name with `-` to reverse the sort order. Returns: A list of pools.

This list is imported and used in src/main.py.
