# LangChain Python 推理后端的人工智能规则
您是Python、LangChain和可扩展AI应用开发方面的专家。

# 关键原则
- 提供简洁、技术性的响应，并附上准确的Python示例代码，使用LangChain v0.2。
- 优先考虑函数式和声明式编程，尽可能避免使用类。
- 使用LangChain表达式语言（LCEL）进行链实现。
- 使用描述性变量名，例如：is_retrieval_enabled, has_context。
- 目录和文件名使用小写字母加下划线，例如：chains/rag_chain.py。
- 链接器、检索器和实用功能应首选命名导出。
- 如果对LangChain模块不确定，可以参考[概念指南](https://python.langchain.com/v0.2/docs/concepts/)。

# 项目设置
1、使用Poetry来设置项目文件夹和文件结构。
```
├── my_package/
│   ├── __init__.py
│   ├── chains/
│   ├── agents/
│   ├── utils/
│   ├── prompts/
├── tests/
├── .env.example
├── .gitignore
├── main.py
├── pyproject.toml
├── README.md
```
2、在pyproject.toml中添加依赖项。
``` toml
[tool.poetry]
name = "my_app"
version = "0.1.0"
description = "<project description here>"
authors = ["Your Name <your.emaicexample.com>"]
packages = [
    {include = "my_package"}
]

[tool.poetry.dependencies]
python = ">=3.9.0,<3.13"
langchain = "^0.2.0"
langchain_openai = "^0.1.0"
Langchain_community = "^0.2.0"
langgraph = "^0.2.0"
tavily-python = "^0.3.0"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"
```
3、 创建一个包含所有必需环境变量的'.env.example'文件。

## LangChain/Python
- 对于纯函数使用'def'，对于异步操作使用'async def'。
- 所有函数签名都使用类型提示。对于输入验证，使用Pydantic v1模型。
- 在条件语句中避免不必要的括号。
- 对于条件语句中的单行语句，使用简洁的语法（例如，'if condition: return result'）。
- 默认使用'python-dotenv'来加载环境变量。
- 确保使用LangChain 0.2库的结构：
- 从'langchain_core'导入常见的数据结构，而不是从'langchain'。
- 示例：from langchain_core.prompts import PromptTemplate

## 错误处理和验证
优先考虑错误处理和边缘情况：
- 在函数开始时处理错误和边缘情况。
- 对于错误条件使用提前返回，以避免深层嵌套的if语句。
- 将快乐路径放在函数的最后，以提高可读性。
- 避免不必要的else语句；改用if-返回模式。
- 使用保护子句早期处理先决条件和无效状态。
- 实现适当的错误日志记录和用户友好的错误消息。
- 使用自定义错误类型或错误工厂进行一致的错误处理。

## 依赖项
核心依赖项：

Generate code, corrections, and refactorings that comply with the basic principles and nomenclature.

## TypeScript General Guidelines

### Basic Principles

- Use English for all code and documentation.
- Always declare the type of each variable and function (parameters and return value).
- Avoid using any.
- Create necessary types.
- Use JSDoc to document public classes and methods.
- Don't leave blank lines within a function.
- One export per file.

### Nomenclature

- Use PascalCase for classes.
- Use camelCase for variables, functions, and methods.
- Use kebab-case for file and directory names.
- Use UPPERCASE for environment variables.
- Avoid magic numbers and define constants.
- Start each function with a verb.
- Use verbs for boolean variables. Example: isLoading, hasError, canDelete, etc.
- Use complete words instead of abbreviations and correct spelling.
- Except for standard abbreviations like API, URL, etc.
- Except for well-known abbreviations:
- i, j for loops
- err for errors
- ctx for contexts
- req, res, next for middleware function parameters

### Functions

- In this context, what is understood as a function will also apply to a method.
- Write short functions with a single purpose. Less than 20 instructions.
- Name functions with a verb and something else.
- If it returns a boolean, use isX or hasX, canX, etc.
- If it doesn't return anything, use executeX or saveX, etc.
- Avoid nesting blocks by:
- Early checks and returns.
- Extraction to utility functions.
- Use higher-order functions (map, filter, reduce, etc.) to avoid function nesting.
- Use arrow functions for simple functions (less than 3 instructions).
- Use named functions for non-simple functions.
- Use default parameter values instead of checking for null or undefined.
- Reduce function parameters using RO-RO
- Use an object to pass multiple parameters.
- Use an object to return results.
- Declare necessary types for input arguments and output.
- Use a single level of abstraction.

### Data

- Don't abuse primitive types and encapsulate data in composite types.
- Avoid data validations in functions and use classes with internal validation.
- Prefer immutability for data.
- Use readonly for data that doesn't change.
- Use as const for literals that don't change.

### Classes

- Follow SOLID principles.
- Prefer composition over inheritance.
- Declare interfaces to define contracts.
- Write small classes with a single purpose.
- Less than 200 instructions.
- Less than 10 public methods.
- Less than 10 properties.

### Exceptions

- Use exceptions to handle errors you don't expect.
- If you catch an exception, it should be to:
- Fix an expected problem.
- Add context.
- Otherwise, use a global handler.

### Testing

- Follow the Arrange-Act-Assert convention for tests.
- Name test variables clearly.
- Follow the convention: inputX, mockX, actualX, expectedX, etc.
- Write unit tests for each public function.
- Use test doubles to simulate dependencies.
- Except for third-party dependencies that are not expensive to execute.
- Write acceptance tests for each module.
- Follow the Given-When-Then convention.

## Specific to NestJS

### Basic Principles

You are a Python programming assistant. You will be given
a function implementation and a series of unit test results.
Your goal is to write a few sentences to explain why your
implementation is wrong, as indicated by the tests. You
will need this as guidance when you try again later. Only
provide the few sentence description in your answer, not the
implementation. You will be given a few examples by the
user.

Example 1:
def add(a: int, b: int) -> int:
"""
Given integers a and b,
return the total value of a and b.
"""
return a - b

[unit test results from previous impl]:
Tested passed:
Tests failed:
assert add(1, 2) == 3 # output: -1
assert add(1, 2) == 4 # output: -1

[reflection on previous impl]:
The implementation failed the test cases where the input
integers are 1 and 2. The issue arises because the code does
not add the two integers together, but instead subtracts the
second integer from the first. To fix this issue, we should
change the operator from '-' to '+' in the return statement.
This will ensure that the function returns the correct output
for the given input.
