This is a starter template for building AI agents that useA2UI andCopilotKit. It provides a modern Next.js application with an integrated restaurant finder agent that can find restaurants and book reservations

• Gemeni API Key (for the ADK/A2A agent)
• Python 3.12+
• uv
• Node.js 20+
• Any of the following package managers:
  • pnpm (recommended)
  • npm
  • yarn
  • bun

Note: This repository ignores lock files (package-lock.json, yarn.lock, pnpm-lock.yaml, bun.lockb) to avoid conflicts between different package managers. Each developer should generate their own lock file using their preferred package manager. After that, make sure to delete it from the .gitignore.

1. Install dependencies using your preferred package manager:

# Using pnpm (recommended)pnpm install# Using npmnpm install# Using yarnyarn install# Using bunbun install

Note: This will automatically setup the Python environment as well.

If you have manual isseus, you can run:

npm run install:agent

3. Set up your Gemeni API key:

Create a.env file inside theagent folder with the following content:

GEMENI_API_KEY=sk-...your-openai-key-here...

4. Start the development server:

# Using pnpmpnpm dev# Using npmnpm run dev# Using yarnyarn dev# Using bunbun run dev

This will start both the UI and agent servers concurrently.

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 PydanticAI agent server
• build - Builds the Next.js application for production
• start - Starts the production server
• lint - Runs ESLint for code linting
• install:agent - Installs Python dependencies for the agent

The main UI component is insrc/app/page.tsx, but most of the UI comes from from the agent in the form of A2UI declarative components. To see and edit the components it can generate, look inagent/prompt_builder.py.To generate new components, try theA2UI Composer

1. The ADK agent is running on port 10002
2. Your Gemini API key is set correctly
3. Both servers started successfully
