Deep Agent

This repository contains a minimal implementation of a Deep Agent inspired by the Deep Agents from Scratch course. The agent can:

1. Search the web (DuckDuckGo).
2. Create, read and combine virtual files.
3. Export the virtual files to the real filesystem.
4. Use LangChain + Ollama for LLM inference.

Setup

# Install dependencies
pip install -r requirements.txt

Usage

python deep_agent.py "Write a summary of the latest Python release and store it in summary.txt"

The agent will perform the task, create virtual files, and export them to output_files/.

Architecture

• DeepAgent class implements the agent logic.
• search uses DuckDuckGo HTML API.
• write_file, read_file, combine manage a simple in‑memory virtual filesystem.
• export_files writes the virtual files to disk.
• The agent loop uses a JSON‑based action protocol.

Requirements

• Python 3.10+
• LangChain >= 1.0.0
• LangGraph >= 1.0.0
• langchain_ollama
• langchain_text_splitters
• langchain_chroma
• requests

Feel free to extend the agent with more actions or integrate other LLM providers.
