What is ReWOO?

ReWOO is an agent architecture designed to improve efficiency and simplify fine-tuning for tool use in AI systems. It features three main modules:

🧠 Planner

• Generates a step-by-step plan in the following format:

  Plan: <reasoning>
  #E1 = Tool[argument for tool]
  Plan: <reasoning>
  #E2 = Tool[argument for tool with #E1 variable substitution]
  ...
  

• Leverages variable substitution to avoid redundant calls to the Planner LLM.

Worker

• Executes the tools using the arguments provided by the Planner.

🧠 Solver

• Generates the final answer for the original task using the observations from the Worker.

Modules marked with a 🧠 emoji involve an LLM call. By consolidating tool usage planning, ReWOO reduces token consumption and execution time compared to ReACT-style architectures.

📤 Set up

Setting Up the Agent and UI

1. Get an GITHUB PAT

2. Clone the Repository

• Clone the repository to your local machine:

  git clone https://github.com/pheonix-coder/cogni-flow.git

3. Set Up the Agent

• Navigate to the agent directory:

  cd agent

• Install dependencies using Poetry:

  poetry install

• Create a .env file inside the ./agent directory with your GITHUB_PAT and TAVILY_API_KEY:

  OPENAI_API_KEY=YOUR_GITHUB_PAT_HERE
  TAVILY_API_KEY=YOUR_TAVILY_API_KEY
  

• Run the agent demo:

  poetry run demo

4. Set Up the UI

• Navigate to the UI directory:

  cd ./ui

• Install dependencies using pnpm:

  pnpm i

• Create a .env file inside the ./ui directory with your GITHUB_PAT:

  OPENAI_API_KEY=YOUR_GITHUB_PAT_HERE
  

• Run the Next.js project:

  pnpm dev

Troubleshooting

1. Ensure no other local application is running on port 8000.
2. In the file /agent/rag_agent/demo.py, change the address from 0.0.0.0 to 127.0.0.1 or localhost if needed.
