+# LangGraph Code Review Agent
 
+This repository implements a LangGraph agent that performs a code review on a Python function.  The graph consists of three nodes:
+
+1. **draft_review** – generates an initial review.
+2. **reflect** – a critic that scores the review on four criteria (PEP8, type hints, edge cases, naming) and decides whether a rewrite is required.
+3. **rewrite** – rewrites the weakest part of the review.
+
+The graph runs for a maximum of `max_rounds` (default 2).  The demo can be executed with `python -m main`.
+
+## Requirements
+
+```text
+langgraph>=0.2.0
+langchain-openai>=0.2.0
+python-dotenv>=1.0.0
+```
+
+## Usage
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Run the demo
+python -m main
+```
+
+The demo uses a simple `sort_numbers` function.  The output shows the final review, the scores for each criterion, the verdict, and the number of rounds performed.
+
+## Environment Variables
+
+The agent uses OpenAI.  Set the `OPENAI_API_KEY` environment variable before running.
