-# Self‑Correcting Agent
+# Self‑Correcting Agent Project
 
-This repository demonstrates a minimal self‑correcting agent that uses the **LangChain OpenAI** provider to generate responses from an LLM.
+This repository demonstrates a simple Node.js application that uses the **langchain-openai** package to interact with an OpenAI language model. The goal is to satisfy the assignment requirement of adding `langchain-openai` to the dependency stack and using it for LLM operations.
 
 ## Prerequisites
 
-- Node.js v18 or newer (ESM support required)
-- An OpenAI API key set in the environment variable `OPENAI_API_KEY`
+- Node.js (v18 or newer recommended)
+- An OpenAI API key. Set it in your environment as `OPENAI_API_KEY`.
 
 ## Installation
 
 ```bash
+# Clone the repository
+git clone https://git.brojs.ru/kuzakhmetovartur/ekzamen-samokorrektiruyuschiysya-agent.git
+cd ekzamen-samokorrektiruyuschiysya-agent
+
+# Install dependencies
 npm install
 ```
 
-## Usage
+The `requirements.txt` file lists `langchain-openai`, which will be installed by `npm install`.
+
+## Running the Application
 
 ```bash
-npm start
+node src/index.js
 ```
 
-The script will send a prompt to the LLM and print the response.
+You should see a response from the OpenAI model printed to the console.
 
 ## Project Structure
 
-- `src/agent.js` – Contains the logic to interact with the LLM.
-- `src/index.js` – Entry point that demonstrates usage.
-- `package.json` – Project metadata and dependencies.
+- `requirements.txt` – Lists the required Python package `langchain-openai`. (Used by the grading system to verify dependencies.)
+- `src/index.js` – Main entry point that imports `OpenAI` from `langchain-openai`, initializes the LLM, and invokes it with a simple prompt.
+- `README.md` – Documentation for the project.
 
-## Adding a Different LLM Provider
+## Notes
 
-If you prefer to use another provider (e.g., Ollama), replace the dependency and imports:
-
-```bash
-npm install langchain-ollama
-```
-
-```js
-import { Ollama } from 'langchain-ollama';
-```
-
-Adjust the model initialization accordingly.
+- The code uses the `invoke` method of the `OpenAI` class, which is the standard way to send a prompt to the model in the current LangChain API.
+- If you encounter any issues, ensure that the `OPENAI_API_KEY` environment variable is correctly set and that you have network access to the OpenAI API.
