Implementation Reference
- src/airflow/variable.py:74-76 (handler)The async handler function that implements the 'delete_variable' tool. It calls the Airflow VariableApi to delete the variable by key and returns a textual representation of the response.async def delete_variable(key: str) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: response = variable_api.delete_variable(variable_key=key) return [types.TextContent(type="text", text=str(response.to_dict()))]
- src/airflow/variable.py:11-19 (registration)Defines the list of tools for the variable module, including the tuple for 'delete_variable' used for registration.def get_all_functions() -> list[tuple[Callable, str, str, bool]]: """Return list of (function, name, description, is_read_only) tuples for registration.""" return [ (list_variables, "list_variables", "List all variables", True), (create_variable, "create_variable", "Create a variable", False), (get_variable, "get_variable", "Get a variable by key", True), (update_variable, "update_variable", "Update a variable by key", False), (delete_variable, "delete_variable", "Delete a variable by key", False), ]
- src/main.py:90-92 (registration)The loop in main() that registers all tools from imported modules (including variable tools) by calling app.add_tool.for func, name, description, *_ in functions: app.add_tool(func, name=name, description=description)
- src/airflow/variable.py:8-8 (helper)The VariableApi instance used by all variable tools, including delete_variable.variable_api = VariableApi(api_client)
