+# Graph with Reflection on Code
 
-Главная
+A lightweight Python project that demonstrates how to build a **LangGraph** workflow powered by **LangChain** and the **OpenAI** API.  
-Мои задания
+The graph processes a piece of code, generates a reflection on it, and returns a concise summary.

+## 📌 Overview
 
-Редактирование ответа
+- **LangGraph** – orchestrates the flow of data between nodes.
+- **LangChain** – provides the language model wrappers and utilities.
+- **OpenAI** – the LLM that performs code analysis and reflection.
 
-Заполните ответ и отправьте работу на проверку преподавателю.
+The workflow consists of three main nodes:
 
-Тип ответа
+1. **Input Node** – receives raw code.
-Текст
+2. **Analysis Node** – calls the OpenAI model to analyze the code.
-Ссылка
+3. **Reflection Node** – generates a reflection and summary.

-Ссылка (URL)
+The graph is defined in `graph.py` and can be executed via the CLI or imported as a library.

+## 🚀 Features
+
+- **Code Analysis** – extracts key functions, classes, and comments.
+- **Reflection Generation** – produces a human‑readable reflection on the code quality, style, and potential improvements.
+- **Modular Design** – each node can be replaced or extended independently.
+- **OpenAI Integration** – uses the `gpt-4o-mini` model by default (configurable).

+## 🛠️ Installation
+
+```bash
+# Clone the repository
+git clone https://git.brojs.ru/kuzakhmetovartur/povtornyy-ekzamen-2-graf-s-refleksiey-na.git
+cd povtornyy-ekzamen-2-graf-s-refleksiey-na
+
+# Create a virtual environment (optional but recommended)
+python -m venv .venv
+source .venv/bin/activate   # On Windows: .venv\Scripts\activate
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+> **Requirements**  
+> - Python 3.10+  
+> - `langgraph`, `langchain`, `openai` (listed in `requirements.txt`)  
+> - An OpenAI API key set as the environment variable `OPENAI_API_KEY`.

+
+## 📦 Usage
+
+### Command‑Line
+
+```bash
+python main.py --file path/to/your_code.py
+```
+
+The script will:
+
+1. Load the file content.
+2. Run it through the LangGraph workflow.
+3. Print the reflection and summary to the console.
+
+### Programmatic
+
+```python
+from graph import CodeReflectionGraph
+
+graph = CodeReflectionGraph()
+result = graph.run(code="def hello():\n    print('Hello, world!')")
+print(result["reflection"])
+```
