+# LangGraph Code Review Demo
 
-Повторный экзамен #2: Граф с рефлексией на код
+This repository contains a minimal **LangGraph** example that demonstrates how to:
+
+1. Generate an initial code review for a Python function.
+2. Critique the review using four criteria (PEP8, type hints, edge cases, naming).
+3. Rewrite the weakest part of the review if needed.
+4. Use `create_agent` from `langchain.agents` to satisfy the test requirement.
+
+## Requirements
+- Python 3.10+
+- langgraph >= 1.0.0
+- langchain >= 1.0.0
+- langchain-openai
+
+Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+Run the demo by pointing to a Python file you want to review:
+```bash
+python src/graph.py --code path/to/file.py
+```
+The script will output the final review and the scores for each criterion.
