## Google ADK Development Tools

Google ADK provides **5 CLI tools** for building, testing, debugging, and deploying agents.

---

## CLI Tools Overview

| Command | Purpose | Use When |
|---------|---------|----------|
| `adk create` | Scaffold new agent project | Starting a new agent |
| `adk run` | Terminal-based agent interaction | Quick testing |
| `adk web` | Visual development UI | Development & debugging |
| `adk api_server` | HTTP API for agent | Integration testing |
| `adk eval` | Run evaluations | Quality assurance |

---

## 1. `adk create` - Scaffold Agent

```bash
# Create code-based agent
adk create my_agent

# Create config-based agent (YAML)
adk create --type=config my_agent
```

Output structure:
```
my_agent/
├── __init__.py
├── agent.py        # agent definition
└── .env            # API keys
```

---

## 2. `adk run` - Terminal Interaction

![ADK Run](https://google.github.io/adk-docs/assets/adk-run.png)

```bash
# Interactive terminal chat
adk run my_agent

# With specific environment
adk run my_agent --env .env.production
```

---

## 3. `adk web` - Visual Dev UI

![ADK Web Chat](https://google.github.io/adk-docs/assets/adk-web-dev-ui-chat.png)

```bash
# Launch web UI on localhost:8000
adk web my_agent

# Custom port
adk web my_agent --port 3000
```

## 4. `adk api_server` - HTTP API

![ADK API Server](https://google.github.io/adk-docs/assets/adk-api-server.png)

```bash
# Start API server
adk api_server my_agent --port 8080
```

```bash
# Test with curl
curl -X POST http://localhost:8080/run \
    -H "Content-Type: application/json" \
    -d '{"user_id": "user-1", "message": "What is RAG?"}'
```

---

## 5. `adk eval` - Run Evaluations

```bash
# Run all tests
adk eval my_agent tests/

# Run specific test file
adk eval my_agent tests/weather.test.json

# Verbose output
adk eval my_agent tests/ --verbose
```
