This is a starter template for building AI agents using Google's ADK and CopilotKit. It provides a modern Next.js application with an integrated investment analyst agent that can research stocks, analyze market data, and provide investment insights.

Prerequisites

Node.js 18+
Python 3.12+
Google Makersuite API Key (for the ADK agent) (see https://makersuite.google.com/app/apikey)
Any of the following package managers:
- npm (default)
- pnpm
- yarn
- bun

Getting Started

Install dependencies using your preferred package manager:

# Using npm (default)
npm install

# Using pnpm
pnpm install

# Using yarn
yarn install

# Using bun
bun install

Note: This will automatically setup a .venv (virtual environment) inside the agent directory.

To activate the virtual environment manually, you can run:
source agent/.venv/bin/activate

Set up your Google API key:

export GOOGLE_API_KEY="your-google-api-key-here"

Start the development server:

# Using npm (default)
npm run dev

# Using pnpm
pnpm dev

# Using yarn
yarn dev

# Using bun
bun run dev

This will start both the UI and agent servers concurrently.

CopilotKit Intelligence & Threads (Optional)

CopilotKit Intelligence provides durable, multi-turn conversation threads with memory persistence. To enable:

Prerequisites

Docker Desktop or equivalent
CopilotKit License Token (get from CopilotKit Cloud)
Intelligence Repository - Clone the CopilotKit Intelligence repository locally

Setup

Clone the Intelligence repository (if not already cloned):

# Clone to a sibling directory (recommended)
cd ..
git clone https://github.com/CopilotKit/Intelligence.git
cd -

Start the intelligence stack:

# Set your license token (if not already in .env)
echo "COPILOTKIT_LICENSE_TOKEN=your-token-here" >> .env

# Set the path to your Intelligence repo checkout
# Default: ../../../Intelligence (assumes CopilotKit monorepo layout)
# For standalone starters, adjust to your actual path:
export INTELLIGENCE_REPO=../Intelligence  # if cloned as sibling

# Start intelligence services (postgres, redis, intelligence API)
docker compose -f docker-compose.intelligence.yml up -d

# Verify services are healthy
docker compose -f docker-compose.intelligence.yml ps

Ensure intelligence configuration in .env (uncomment if already present):

COPILOTKIT_LICENSE_TOKEN=your-token-here
INTELLIGENCE_API_URL=http://localhost:4201
INTELLIGENCE_GATEWAY_WS_URL=ws://localhost:4401

Run your application:

npm run dev

The intelligence stack will now handle conversation threads, state persistence, and memory. See docker-compose.intelligence.yml and docker/01-create-databases.sql for configuration details.

Note: The Intelligence service is built from source and requires the Intelligence repository. If you're using this as a standalone starter (extracted from the CopilotKit monorepo), you must clone the Intelligence repo separately and set INTELLIGENCE_REPO to point to it.

Stopping Intelligence

# Stop services (keeps data)
docker compose -f docker-compose.intelligence.yml stop

# Stop and remove containers + volumes (fresh start)
docker compose -f docker-compose.intelligence.yml down -v

Available Scripts

The following scripts can also be run using your preferred package manager:

dev - Starts both UI and agent servers in development mode
dev:debug - Starts development servers with debug logging enabled
dev:ui - Starts only the Next.js UI server
dev:agent - Starts only the ADK agent server
build - Builds the Next.js application for production
start - Starts the production server
install:agent - Installs Python dependencies for the agent

Documentation

The main UI component is in src/app/page.tsx. You can:

Modify the theme colors and styling
Add new frontend actions
Customize the CopilotKit sidebar appearance

The ADK agent is running on port 8000
Your Google API key is set correctly
Both servers started successfully

Python Dependencies

If you encounter Python import errors:

cd agent
pip install -r requirements.txt
