説明

from langchain_core.tools import tool
from pydantic import BaseModel


class MyTool(BaseModel):
    """Parent Tool"""
    foo: str

@tool
class ChildTool(MyTool):
    bar: str
For 0.4 release we could consider updating the behavior so that doc-strings are not inherited from their parents. It's fairly odd that doc-strings are inherited for BaseModels as in general the descriptions need to be different

調査方針: The issue requests that the @tool decorator should not inherit docstrings from parent Pydantic models. Examine the current implementation in langchain core/tools/base.py, specifically how the decorator handles doc attributes. Refer to the original discussion in issue #31606 for context. Discuss with the assignee any design decisions and then implement a change that prevents docstring inheritance, ensuring compatibility with the upcoming 0.4 release.
