'Review a concise docstring for the class named PDFSlicerConfig.\nYou must output only the text, with no triple quotes, no markdown fences, no indentation and no class definition line. You should use the surrounding code to better understand and correctly document the class.\n\nStyle preferences:\n\n- Always write in Google style.\n- Always add "Defaults to x", at the end for values with defaults.\n\n\n\nInput for class Rectangle (Python source snippet):\n\npython\nclass Rectangle:\n """\n Represents a rectangle in 2-D space\n\n Attributes:\n width (float): The rectangle\'s width.\n height (float): The rectangle\'s height.\n \n Methods:\n area (float): Return the area of the rectangle.\n """\n\n def __init__(self, width: float, height: float):\n self.width = width\n self.height = height\n\n def area(self) -> float:\n return self.width * self.height\n\n\nExpected Output:\n\n{\n "should_update": false,\n "docstring_review": "Docstring ok",\n "new_docstring": null\n}\n\nInput for class Person (Python source snippet):\n\npython\nclass Person:\n """Simple repretation of a person."""\n\ndef __init__(self, name: str, age: int):\n self.name = name\n self.age = age\n\n def greet(self) -> str:\n return f"Hello, my name is {self.name}."\n\n\n\nExpected Output:\n\n{\n "should_update": true,\n "docstring_review": "Docstring typo, missing attributes and arguments",\n "new_docstring": "Represents a person with a name and age.\n\nClass Attributes:\n species (str): Scientific name for all humans.\n\nInstance Attributes:\n name (str): The person's name.\n age (int): The person's age in years.\n\nMethods:\n greet() -> str: Return a friendly greeting that includes the person's name."\n}\n\n\n\n\n\n\nThis is the full code:\n\npython\nfrom dataclasses import dataclass\nimport PyPDF2\nimport os\nfrom pydantic import BaseModel\nimport yaml\n\n\nclass PDFSlicerConfigEntry(BaseModel):\n """\n Configuration for a single PDF file and page range.\n \n Attributes:\n input_file (str): The path to the input PDF file.\n splits (tuple[int, int] | None): A tuple representing the start and end page numbers for slicing.
