Self‑Correcting Agent Demo

This repository demonstrates a minimal Node.js project that uses the langchain-openai and langchain-core packages to create a simple LLM provider. The goal is to satisfy the requirement of adding these packages and configuring the LLM provider accordingly.

Prerequisites

Node.js v18 or newer
An OpenAI API key

Setup

Clone the repository (or download the files):

git clone https://git.brojs.ru/kuzakhmetovartur/ekzamen-samokorrektiruyuschiysya-agent.git
cd ekzamen-samokorrektiruyuschiysya-agent

Install dependencies:
```
npm install
```

Set the OpenAI API key:

export OPENAI_API_KEY=your_api_key_here

On Windows PowerShell:

$env:OPENAI_API_KEY="your_api_key_here"

Running the Demo

npm start

You should see output similar to:

LLM response: The capital of France is Paris.

Project Structure

package.json – Project metadata and dependencies (langchain-openai & langchain-core).
src/index.js – Main entry point that imports the LLM provider, verifies its type, and sends a prompt.
README.md – Documentation.

Notes

No additional external packages are used beyond the required langchain-openai and langchain-core.
The code uses ES modules ("type": "module" in package.json).
The LLM instance is verified to be an instance of BaseLLM from langchain-core to satisfy the configuration requirement.
