# Neuron AI Agent Builder

This skill helps you create and configure Neuron AI agents for building agentic applications in PHP.

## Core Agent Structure

A Neuron agent extends the `Agent` class and implements key methods:

```php
use NeuronAI\Agent;
use NeuronAI\Agent\SystemPrompt;
use NeuronAI\Providers\AIProviderInterface;
use NeuronAI\Providers\Anthropic\Anthropic;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        return new Anthropic(
            key: 'ANTHROPIC_API_KEY',
            model: 'ANTHROPIC_MODEL',
        );
    }

    protected function instructions(): string
    {
        return (string) new SystemPrompt(
            background: [
                "You are a helpful AI assistant."
            ]
        );
    }
}
```

## Agent Execution Methods

### Chat Mode (Synchronous)
For standard back-and-forth conversations:

```php
$agent = MyAgent::make();
$response = $agent->chat(
    new UserMessage("Hello!")
)->getMessage();
echo $response->getContent();
```

### Stream Mode (Real-time)
For streaming responses as tokens arrive:

```php
foreach ($agent->stream(new UserMessage("Hello"))->events() as $event) {
    if ($event instanceof AIResponseChunkEvent) {
        echo $event->chunk;
    }
}
```

### Structured Output Mode
For extracting structured data from natural language:

```php
class Person
{
    #[SchemaProperty(description: 'The user name', required: true)]
    public string $name;

    #[SchemaProperty(description: 'What the user loves to eat')]
    public string $preference;
}

$person = $agent->structured(
    new UserMessage("I'm John and I like pizza!"),
    Person::class
);
```

## Providers Configuration

### Anthropic
```php
new Anthropic(
    key: $_ENV['ANTHROPIC_API_KEY'],
    model: 'claude-3-5-sonnet-20241022',
)
```

### OpenAI
```php
new OpenAI(
    key: $_ENV['OPENAI_API_KEY'],
    model: 'gpt-4',
)
```

### Ollama (Local)
```php
new Ollama(
    baseUrl: 'http://localhost:11434',
    model: 'llama3',
)
```

### Other Providers
- `Gemini` - Google AI models
- `Mistral` - Mistral AI models
- `HuggingFace` - Open models via HuggingFace
- `Deepseek` - DeepSeek models
- `Grok` - XAI models
- `AWSBedrockRuntime` - AWS Bedrock models
- `Cohere` - Cohere models

## Tools Integration

### Adding Built-in Toolkits

```php
use NeuronAI\Tools\Toolkits\MySQL\MySQLToolkit;
use NeuronAI\Tools\Toolkits\Calculator\CalculatorToolkit;

protected function tools(): array
{
    return [
        MySQLToolkit::make(\DB::connection()->getPdo()),
        CalculatorToolkit::make(),
    ];
}
```

### Available Toolkits
- **MySQLToolkit** - Database queries via MySQL
- **PostgreSQLToolkit** - Database queries via PostgreSQL
- **CalculatorToolkit** - Math operations (sum, mean, std, etc.)
- **TavilyToolkit** - Web search with Tavily
- **SESToolkit** - Email sending via AWS SES
- **JinaToolkit** - Reranking with Jina

### Creating Custom Tools

```php
use NeuronAI\Tools\Tool;
use NeuronAI\Tools\ToolProperty;

class WeatherTool extends Tool
{
    public function __construct()
    {
        parent::__construct(
            name: 'get_weather',
            description: 'Get the current weather for a location',
            properties: [
                new ToolProperty(
                    name: 'location',
                    type: ToolPropertyType::String,
                    description: 'The city name',
                    required: true,
                ),
            ],
        );
    }

    public function execute(array $arguments): mixed
    {
        $location = $arguments['location'];
        // Call weather API and return result
        return "The weather in {$location} is sunny, 72°F";
    }
}
```

## System Prompt Engineering

Use `SystemPrompt` for structured agent instructions:

```php
new SystemPrompt(
    background: [
        "You are a data analyst expert in creating reports.",
    ],
    steps: [
        "Analyze the user's request",
        "Query the database",
        "Generate a summary",
    ],
    constraints: [
        "Always cite your sources",
        "Never make up data",
    ],
    outputFormat: [
        "Provide executive summary first",
        "Follow with detailed breakdown",
    ],
)
```

## Memory and Chat History

Agents automatically maintain conversation history. For custom memory:

```php
use NeuronAI\Agent\Memory\FileMemory;

// In agent class
protected function memory(): MemoryInterface
{
    return new FileMemory('/path/to/memory.json');
}
```

### Memory Types
- `InMemoryMemory` - Default, session-based
- `FileMemory` - Persist to file
- `SQLMemory` - Database-backed

## Content Blocks (Multi-modal)

Agents support multiple content types:

```php
use NeuronAI\Chat\Messages\ContentBlocks\TextContent;
use NeuronAI\Chat\Messages\ContentBlocks\ImageContent;
use NeuronAI\Chat\Enums\SourceType;

$message = new UserMessage([
    new TextContent('Analyze this image:'),
    new ImageContent(
        content: 'https://example.com/image.jpg',
        sourceType: SourceType::URL,
        mediaType: 'image/jpeg'
    ),
]);
```

## CLI Generation

Use the Neuron CLI to generate agent boilerplate:

```bash
php vendor/bin/neuron make:agent MyCustomAgent
```

## Common Patterns

### Tool Approval Middleware
For human oversight of tool execution:

```php
use NeuronAI\Agent\Middleware\ToolApproval;

// In agent constructor or configuration
$this->middleware(ToolApproval::class, new ToolApproval());
```

### Observability with Inspector
Monitor agent execution:

```bash
# Set environment variable
INSPECTOR_INGESTION_KEY=your_key_here
```

### Parallel Tool Calls
Execute tools in parallel (requires pcntl):

```php
$agent->setConfig(['parallelToolCalls' => true]);
```

## Key Decisions

When helping users build agents:

1. **Choose execution mode** based on requirements:
   - `chat()` for standard conversations
   - `stream()` for real-time streaming
   - `structured()` for data extraction

2. **Select provider** based on:
   - Cost considerations
   - Required features (e.g., tool calling support)
   - Latency requirements
   - Model capabilities

3. **Add tools** when agent needs to:
   - Access external systems (databases, APIs)
   - Perform calculations
   - Search the web
   - Send emails

4. **Configure memory** when:
   - Long-running conversations need persistence
   - Multiple sessions should share history
   - Memory needs to be shared across agents

5. **Use middleware** for:
   - Logging and monitoring
   - Tool approval workflows
   - Custom pre/post processing

## Project Structure Considerations

For Laravel projects:
```php
namespace App\Neuron;

class MyAgent extends Agent { ... }
```

For Symfony projects:
- Use dependency injection for providers
- Configure as service in services.yaml

## Testing

```php
use PHPUnit\Framework\TestCase;

class MyAgentTest extends TestCase
{
    public function testAgentChat(): void
    {
        $agent = MyAgent::make();
        $response = $agent->chat(
            new UserMessage('Hello')
        )->getMessage();

        $this->assertNotEmpty($response->getContent());
    }
}
```
