+# Research Brief LangGraph Agent
 
+## What it does
+This repository contains a **LangGraph** agent that builds a short research brief for any given topic. The brief is produced in three stages:
+
+1. **Outline** – the LLM generates 4‑5 concise bullet points.
+2. **Research step** – each outline item triggers one web search via Tavily and produces a short note (5–8 sentences).
+3. **Synthesize** – all notes are combined into a coherent brief with headings.
+
+The agent is fully automated; running the script will print the outline, individual notes and the final brief.
+
+## File structure
+- `agent.py` – main implementation of the LangGraph graph.
+- `requirements.txt` – Python dependencies.
+- `README.md` – this documentation.
+
+## Installation
+```bash
+pip install -r requirements.txt
+```
+
+Create a `.env` file in the project root with your Tavily API key:
+```
+TAVILY_API_KEY=your_key_here
+JOURNAL_MCP_PAT=your_brojs_pat   # required for LLM access
+```
+
+## Usage
+```bash
+python agent.py
+```
+The script will run a demo with the default topic *"Как студенту безопасно подключать MCP к LangChain"*.
+
+You can also import `BriefGraph` from `agent` and use it in your own code.
