+## Overview
+This repository implements a **LangGraph** agent that generates a short research brief for any given topic. The agent follows the assignment specification:
+
+1. Create an outline of 4‑5 bullet points.
+2. For each point perform one web search via Tavily and collect a concise note.
+3. Synthesize all notes into a coherent brief (≈½–1 page).
+
+The implementation uses:
+- `langgraph` – graph orchestration
+- `langchain-openai` – LLM calls to the BroJS GPT‑OSS model
+- `langchain-tavily` – web search via Tavily API
+- `python-dotenv` – environment variable loading (TAVILY_API_KEY, JOURNAL_MCP_PAT)
+
+## Installation
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+```bash
+# Run the agent for a specific topic
+python main.py "How to integrate LangGraph with Tavily"
+```
+The script prints:
+- The generated outline
+- Notes collected from web searches
+- Final research brief
+
+You can also import `run_brief` in your own code.
