使用 ClientAI 和 Ollama 构建本地 AI 代码审查器 - 第 2 部分
在第 1 部分中,我们为代码审查器构建了核心分析工具。现在我们将创建一个可以有效使用这些工具的人工智能助手。我们将逐步介绍每个组件,解释所有组件如何协同工作。

使用 clientai 注册我们的工具
首先,我们需要让我们的工具可供人工智能系统使用。以下是我们注册它们的方法:
def create_review_tools() -> list[toolconfig]: """create the tool configurations for code review.""" return [ toolconfig( tool=analyze_python_code, name="code_analyzer", description=( "analyze python code structure and complexity. " "expects a 'code' parameter with the python code as a string." ), scopes=["observe"], ), toolconfig( tool=check_style_issues, name="style_checker", description=( "check python code style issues. " "expects a 'code' parameter with the python code as a string." ), scopes=["observe"], ), toolconfig( tool=generate_docstring, name="docstring_generator", description=( "generate docstring suggestions for python code. " "expects a 'code' parameter with the python code as a string." ), scopes=["act"], ), ]
让我们来分解一下这里发生的事情:
每个工具都包装在一个 toolconfig 对象中,该对象告诉 clientai:
我们将工具分为两类:
构建ai助手类
现在让我们创建我们的人工智能助手。我们将其设计为分步骤工作,模仿人类代码审查者的想法:
class codereviewassistant(agent): """an agent that performs comprehensive python code review.""" @observe( name="analyze_structure", description="analyze code structure and style", stream=true, ) def analyze_structure(self, code: str) -> str: """analyze the code structure, complexity, and style issues.""" self.context.state["code_to_analyze"] = code return """ please analyze this python code structure and style: the code to analyze has been provided in the context as 'code_to_analyze'. use the code_analyzer and style_checker tools to evaluate: 1. code complexity and structure metrics 2. style compliance issues 3. function and class organization 4. import usage patterns """
第一个方法至关重要:
接下来,我们添加改进建议步骤:
@think( name="suggest_improvements", description="suggest code improvements based on analysis", stream=true, ) def suggest_improvements(self, analysis_result: str) -> str: """generate improvement suggestions based on the analysis results.""" current_code = self.context.state.get("current_code", "") return f""" based on the code analysis of: ```{% endraw %}python {current_code}{% raw %} ``` and the analysis results: {analysis_result} please suggest specific improvements for: 1. reducing complexity where identified 2. fixing style issues 3. improving code organization 4. optimizing import usage 5. enhancing readability 6. enhancing explicitness """
这个方法:
命令行界面
现在让我们创建一个用户友好的界面。我们将其分解为几个部分:
def main(): # 1. set up logging logger = logging.getlogger(__name__) # 2. configure ollama server config = ollamaserverconfig( host="127.0.0.1", # local machine port=11434, # default ollama port gpu_layers=35, # adjust based on your gpu cpu_threads=8, # adjust based on your cpu )
第一部分设置错误日志记录,使用合理的默认值配置 ollama 服务器,并允许自定义 gpu 和 cpu 使用情况。
接下来,我们创建ai客户端和助手:
# use context manager for ollama server with ollamamanager(config) as manager: # initialize clientai with ollama client = clientai( "ollama", host=f"http://{config.host}:{config.port}" ) # create code review assistant with tools assistant = codereviewassistant( client=client, default_model="llama3", tools=create_review_tools(), tool_confidence=0.8, # how confident the ai should be before using tools max_tools_per_step=2, # maximum tools to use per step )
此设置的要点:
最后,我们创建交互式循环:
print("code review assistant (local ai)") print("enter python code to review, or 'quit' to exit.") print("end input with '###' on a new line.") while true: try: print("" + "=" * 50 + "") print("enter code:") # collect code input code_lines = [] while true: line = input() if line == "###": break code_lines.append(line) code = "".join(code_lines) if code.lower() == "quit": break # process the code result = assistant.run(code, stream=true) # handle both streaming and non-streaming results if isinstance(result, str): print(result) else: for chunk in result: print(chunk, end="", flush=true) print("") except exception as e: logger.error(f"unexpected error: {e}") print("an unexpected error occurred. please try again.")
此界面:
让我们将其设为我们能够运行的脚本:
if __name__ == "__main__": main()
使用助手
让我们看看助手如何处理真实的代码。让我们运行一下:
python code_analyzer.py
这是一个需要查找问题的示例:
def calculate_total(values,tax_rate): Total = 0 for Val in values: if Val > 0: if tax_rate > 0: Total += Val + (Val * tax_rate) else: Total += Val return Total
小助手会多方面分析:
扩展思路
以下是增强助手的一些方法:
通过创建新的工具函数,将其包装为适当的 json 格式,将其添加到 create_review_tools() 函数,然后更新助手的提示以使用新工具,可以添加其中的每一个。
