This developer-focused cookbook demonstrates how to build and run a local multi-agent investment research system using AgentStack, CrewAI, and Dappier, powered by OpenAI and monitored via AgentOps. The setup guides you through generating structured investment reports from real-time financial and company data. In this tutorial, you’ll explore:
  • AgentStack: A CLI-first framework for rapidly scaffolding AI agent workflows, generating agents, tasks, and tools with seamless CrewAI integration.
  • CrewAI: A lightweight multi-agent orchestration engine, perfect for managing sequential or collaborative task execution between agents.
  • Dappier: A platform that connects LLMs to real-time, rights-cleared data sources like stock market data, web search, and financial news.
  • OpenAI: A powerful language model provider, enabling natural language understanding, real-time reasoning, and content generation.
  • AgentOps: A monitoring tool to track, replay, and analyze agent runs with detailed visibility into agent reasoning and tool use.
This guide walks you through creating a local, production-grade AI research agent system to analyze companies like Amazon, generate investment snapshots, and compile markdown-formatted financial reports β€” all grounded in real-time market data from Dappier.
πŸ› οΈ All tasks and agents in this cookbook are generated using agentstack commands and executed in a Python project on your local machine. No notebooks, no server setup required.

πŸ“¦ Project Initialization and Setup

To get started, we’ll use the agentstack CLI to scaffold a fully functional multi-agent project. This command generates the base project structure, config files, virtual environment, and a ready-to-customize crew.py file with support for tools like Dappier and frameworks like CrewAI.

Step 1: Initialize the Project

Run the following command in your terminal:
This will generate a folder named stock_market_research with the complete project structure.

Step 2: Move Into the Project

Step 3: Activate the Virtual Environment

Activate the virtual environment created by agentstack:
If you’re using a Windows terminal, use:
βœ… You now have a fully bootstrapped multi-agent AI project using AgentStack and CrewAI.

πŸ”‘ Setting Up API Keys

To enable real-time data access and AI reasoning, you’ll need API keys for the following services:
  • OpenAI – for LLM-powered reasoning and summarization
  • Dappier – for real-time stock market data and web search
  • AgentOps – for run monitoring and debugging
These keys are stored in the .env file created during project initialization.

Step 1: Open the .env file

Inside your project root, open .env and update it with your API keys:
You can get your keys here:
  • πŸ”‘ Get your OpenAI API Key here
  • πŸ”‘ Get your Dappier API Key here β€” free credits available
  • πŸ”‘ Get your AgentOps API Key here - enables run tracking and replay
πŸ§ͺ Make sure to keep these keys private. Do not commit .env to version control.

βš™οΈ Installing Dependencies

After initializing the project and configuring your API keys, install the required dependencies to ensure everything runs smoothly. The key packages used in this project are:
  • crewai – Multi-agent execution and orchestration
  • agentstack – CLI toolchain for generating agents, tasks, and crews
  • dappier – Real-time data access layer for tools like stock search and news
  • openai – LLM access to GPT-4o and other OpenAI models (automatically included)

Step 1: Sync All Dependencies from pyproject.toml

If you’re using the pre-generated project setup from agentstack init, run:
  • uv lock will generate the uv.lock file based on your pyproject.toml
  • uv sync will install all dependencies into the virtual environment

Step 2: Add or Upgrade Individual Packages

You need to upgrade packages manually, use:
βœ… You now have all the required dependencies installed locally and locked for reproducible agent execution.

πŸ‘€ Creating Agents

Now that your environment is ready, let’s generate the agents that will power the stock market research workflow. These agents are created using the AgentStack CLI and are defined declaratively in agents.yaml.

Step 1: Generate the Agents

You’ll use the following command to scaffold each agent:
You’ll be prompted to enter the agent’s name, role, goal, backstory, and model. Repeat this step for each agent in your system. Here are the agents created for this project:

🧠 web_researcher

πŸ“Š stock_insights_analyst

πŸ“ report_analyst

Once generated, AgentStack automatically adds these to your agents.yaml file.
πŸ‘₯ These agents will work together to build a real-time stock market report using data from Dappier and OpenAI reasoning.

βœ… Creating Tasks

Each task defines a specific responsibility to be performed by one of the agents. In this project, tasks are tightly scoped and executed sequentially by CrewAI, allowing agents to collaborate and generate a full investment report. Tasks are defined declaratively in tasks.yaml and are created using the AgentStack CLI.

Step 1: Generate Tasks Using the CLI

Run the following command to create a new task:
You’ll be prompted to provide:
  • task_name (required)
  • --description – a detailed instruction including {company_name} and {timestamp}
  • --expected_output – structured data, tables, or markdown expected from the task
  • --agent – the agent responsible for this task
Here are the tasks used in this project:

🏒 company_overview

πŸ“‰ financials_performance

πŸ†š competitive_benchmarking

πŸ’Ή real_time_stock_snapshot

πŸ“° news_and_sentiment

πŸ“„ generate_investment_report

⚠️ The following two fields must be added manually to the generate_investment_report task inside tasks.yaml, as they are not currently supported via the CLI:
πŸͺ„ All of the above tasks will be executed in sequence using CrewAI when you run the crew.

πŸ› οΈ Adding Tools to Agents

Tools enable agents to interact with external services like Dappier. In this project, Dappier provides real-time access to financial data and web search, powering all the data-gathering tasks.

Step 1: Add Dappier Tools to the Project

Instead of manually assigning tools one-by-one, you can add all Dappier tools at once using:
This will register the full Dappier toolset to the project and make it available through the agentstack.tools["dappier"] registry.

Step 2: Select Specific Tools Per Agent in Code

Instead of assigning tools via CLI, agents in this project filter and attach only the tools they need using a custom helper function in crew.py:
Then each agent uses this function to assign a single tool:

🧠 web_researcher

πŸ“Š stock_insights_analyst

βš™οΈ This approach ensures that each agent only receives the exact tool it needs, while keeping tool registration centralized and clean.

πŸ“ Providing Inputs & Setting Timestamps

Before running the crew, you need to define the runtime inputs that agents and tasks will use. The AgentStack project already includes an inputs.yaml file, which is used to inject these inputs when the crew is executed. In this project, we use two dynamic inputs:
  • company_name: The company to analyze (e.g., β€œtesla”)
  • timestamp: The current UTC time, injected automatically via code

Step 1: Update inputs.yaml

Open the pre-generated inputs.yaml file and set the target company:
You can modify "tesla" to any other publicly traded company.

Step 2: Inject a Real-Time Timestamp in main.py

To provide the current timestamp at execution time, update the run() function in main.py:
This will:
  • Dynamically inject the current UTC timestamp into the input dictionary
  • Allow all tasks referencing {timestamp} in tasks.yaml to use consistent timing context
⏱️ Timestamped input ensures your reports are anchored to the moment of execution.

πŸš€ Running the Crew

Once your agents, tasks, tools, and inputs are all set up, you’re ready to run the multi-agent crew. The crew will execute each task in sequence, collaborating to generate a fully structured investment research report using real-time data.

Step 1: Run the AgentStack Project

To start the crew execution, run the following command from the project root:
This command:
  • Loads your agents from agents.yaml
  • Loads your tasks from tasks.yaml
  • Injects inputs from inputs.yaml (including the runtime timestamp)
  • Executes all tasks sequentially via CrewAI
  • Stores the final output (e.g., markdown report) in the path defined in tasks.yaml
βœ… You should see terminal output as each agent completes its assigned task.

Step 2: Debug with --debug Mode (Optional)

For detailed execution traces, run with the debug flag:
This enables verbose logging, including:
  • Which agent is running
  • Which tool is being used
  • Real-time function call results
  • Intermediate outputs for each task
πŸ§ͺ Use debug mode to troubleshoot tool usage or model behavior during each step.

Step 3: View the Final Output

After the crew finishes execution, you’ll find the generated investment report at:
You can open this file in any markdown viewer or commit it to your workspace.
πŸ“„ The final report contains company overviews, financials, benchmarking, stock data, categorized news, and AI-generated insight β€” all compiled in real time.

πŸ“Š Viewing Agent Run Summary in AgentOps

This project integrates with AgentOps to provide full visibility into agent execution, tool calls, and token usage. By setting the AGENTOPS_API_KEY in your .env file, all runs are automatically tracked. Below is a sample AgentOps run for this project:
  • Duration: 07m 55s
  • Cost: $0.1053500
  • LLM Calls: 43
  • Tool Calls: 9
  • Tokens: 73,770
Description You can view the complete execution trace, including tool calls, function arguments, and model responses in AgentOps.
Note: The AgentOps link shown above is tied to the AgentOps account. To access your own replay, you must run the crew using your personal AGENTOPS_API_KEY.
