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.

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
