  Handler that checks arguments with isLabelIdArgs, calls todoistClient.deleteLabel on the provided labelId, and returns success or error message.

  if (name === "todoist_delete_label") {
    if (!isLabelIdArgs(args)) {
      return { content: [{ type: "text", text: "Invalid arguments for delete_label" }], isError: true };
    }
    try {
      await todoistClient.deleteLabel(args.labelId);
      return { 
        content: [{ type: "text", text: `Label ${args.labelId} deleted.` }], 
        isError: false 
      };
    } catch (error: any) {
      return { content: [{ type: "text", text: `Error deleting label: ${error.message}` }], isError: true };
    }
  }

• src/index.ts:351-361 (schema)

    description: "Delete a label by its ID.",
    inputSchema: {
      type: "object",
      properties: {
        labelId: { type: "string", description: "The ID of the label to delete." }

  } {
    return (
      typeof args === "object" &&
