# Self-Correcting Agent

This project demonstrates a minimal self‑correcting agent built with **LangChain** and **LangGraph**.  
The agent simply echoes user input, but the structure can be extended to include more complex logic and tools.

## Setup

```bash
# Install Python dependencies
pip install -r requirements.txt

# (Optional) Install Node.js dependencies if needed
npm install
```

## Running

```bash
python main.py
```

You should see output similar to:

```
Resulting state:
HumanMessage: Hello, agent!
AIMessage: Echo: Hello, agent!
```

## Project Structure

- `src/` – Core logic (nodes and graph construction).
- `main.py` – Entry point that builds and runs the graph.
- `requirements.txt` – Python dependencies.
- `package.json` – Node.js dependencies (optional).
- `README.md` – Project documentation.

Feel free to extend the nodes or add new tools to create a more sophisticated agent.
