# Modulo Agents

Conversazioni e messaggi con agenti IA tramite `base44.agents`.

> **Nota:** questo modulo richiede un utente loggato. Tutti i metodi degli agenti funzionano nel contesto dell'utente autenticato.

## Contenuti

* [Concetti](#concetti)
* [Metodi](#metodi)
* [Esempi](#esempi) (Creazione, Ottenere conversazioni, Elenco, Sottoscrizione, Invio messaggio, WhatsApp)
* [Struttura del messaggio](#struttura-del-messaggio)
* [Struttura della conversazione](#struttura-della-conversazione)
* [Pattern comuni](#pattern-comuni)

## Concetti

* **Conversazione**: un dialogo tra utente e un agente IA. Ha un ID univoco, il nome dell'agente, il riferimento all'utente e metadati.
* **Messaggio**: singolo messaggio in una conversazione. Ha un ruolo (`user`, `assistant`, `system`), contenuto, timestamp e metadati opzionali.

## Esempi

### Creare una conversazione

```javascript theme={null}
const conversation = await base44.agents.createConversation({
  agent_name: "support-agent",
  metadata: {
    order_id: "ORD-123",
    category: "billing"
  }
});

console.log(conversation.id);
```

### Ottenere tutte le conversazioni

```javascript theme={null}
const conversations = await base44.agents.getConversations();

conversations.forEach(conv => {
  console.log(conv.id, conv.agent_name, conv.created_date);
});
```

### Ottenere una singola conversazione (con messaggi)

Restituisce la conversazione memorizzata completa inclusi i risultati completi delle chiamate agli strumenti (a differenza della sottoscrizione in tempo reale, che tronca i dati delle chiamate agli strumenti).

```javascript theme={null}
const conversation = await base44.agents.getConversation("conv-id-123");

console.log(conversation.messages);
```

### Elenco con filtri

```javascript theme={null}
// Using filterParams object with q, sort, limit, skip, fields
const recent = await base44.agents.listConversations({
  q: { agent_name: "support-agent" },
  sort: "-created_date",
  limit: 10,
  skip: 0
});

// Filter by metadata
const highPriority = await base44.agents.listConversations({
  q: {
    agent_name: "support-agent",
    "metadata.priority": "high"
  },
  sort: "-updated_date",
  limit: 20
});
```

### Sottoscrivere gli aggiornamenti (tempo reale)

Quando ricevi messaggi tramite questa sottoscrizione, i dati delle chiamate agli strumenti sono troncati per efficienza (`arguments_string` limitato a 500 caratteri, `results` a 50). Usa `getConversation()` dopo che il messaggio è completato per recuperare i dati completi delle chiamate agli strumenti.

```javascript theme={null}
const unsubscribe = base44.agents.subscribeToConversation(
  "conv-id-123",
  (updatedConversation) => {
    // Called when new messages arrive
    console.log("New messages:", updatedConversation.messages);
  }
);

// Later: unsubscribe
unsubscribe();
```

### Inviare un messaggio

```javascript theme={null}
const conversation = await base44.agents.getConversation("conv-id-123");

await base44.agents.addMessage(conversation, {
  role: "user",
  content: "What's the weather like today?"
});
```

### Ottenere l'URL di connessione WhatsApp

```javascript theme={null}
const whatsappUrl = base44.agents.getWhatsAppConnectURL("support-agent");
// Returns URL for users to connect with agent via WhatsApp
console.log(whatsappUrl);
```

## Struttura del messaggio

```javascript theme={null}
{
  role: "user" | "assistant" | "system",
  content: "Message text or structured object",
  created_date: "2024-01-15T10:30:00Z",
  updated_date: "2024-01-15T10:30:00Z",
  
  // Optional fields
  reasoning: {
    content: "Agent's reasoning process",
    timing: 1500
  },
  tool_calls: [{
    name: "search",
    arguments: { query: "weather" },
    result: { ... },
    status: "success"
  }],
  file_urls: ["https://..."],
  usage: {
    prompt_tokens: 150,
    completion_tokens: 50
  },
  metadata: { ... },
  custom_context: { ... }
}
```

## Struttura della conversazione

```javascript theme={null}
{
  id: "conv-id-123",
  app_id: "app-id",
  agent_name: "support-agent",
  created_by_id: "user-id",
  created_date: "2024-01-15T10:00:00Z",
  updated_date: "2024-01-15T10:30:00Z",
  messages: [ ... ],
  metadata: { ... }
}
```

## Pattern comuni

### Interfaccia di chat

```javascript theme={null}
// Load conversation
const conv = await base44.agents.getConversation(conversationId);
setMessages(conv.messages);

// Subscribe to updates
const unsubscribe = base44.agents.subscribeToConversation(conversationId, (updated) => {
  setMessages(updated.messages);
});

// Send message
async function sendMessage(text) {
  await base44.agents.addMessage(conv, { role: "user", content: text });
}

// Cleanup on unmount
return () => unsubscribe();
```

## Definizioni di tipo

### AgentNameRegistry e AgentName

**Come ottenere nomi di agenti tipizzati:** la CLI di Base44 può generare un'estensione di `AgentNameRegistry` dal tuo progetto. Per come eseguirla, usa la skill **base44-cli**.

```typescript theme={null}
/**
 * Registry of agent names.
 * Augment this interface to enable autocomplete for agent names.
 * Typically populated by the Base44 CLI type generator.
 */
interface AgentNameRegistry {}

/**
 * Agent name type - uses registry keys if augmented, otherwise string.
 */
type AgentName = keyof AgentNameRegistry extends never ? string : keyof AgentNameRegistry;
```

### AgentConversation

```typescript theme={null}
/** An agent conversation containing messages exchanged with an AI agent. */
interface AgentConversation {
  /** Unique identifier for the conversation. */
  id: string;
  /** Application ID. */
  app_id: string;
  /** Name of the agent in this conversation. */
  agent_name: string;
  /** ID of the user who created the conversation. */
  created_by_id: string;
  /** When the conversation was created. */
  created_date: string;
  /** When the conversation was last updated. */
  updated_date: string;
  /** Array of messages in the conversation. */
  messages: AgentMessage[];
  /** Optional metadata associated with the conversation. */
  metadata?: Record<string, any>;
}
```

### AgentMessage

```typescript theme={null}
/** A message in an agent conversation. */
interface AgentMessage {
  /** Unique identifier for the message. */
  id: string;
  /** Role of the message sender. */
  role: "user" | "assistant" | "system";
  /** When the message was created. */
  created_date: string;
  /** When the message was last updated. */
  updated_date: string;
  /** Message content. */
  content?: string | Record<string, any>;
  /** Optional reasoning information for the message. */
  reasoning?: AgentMessageReasoning | null;
  /** URLs to files attached to the message. */
  file_urls?: string[];
  /** Tool calls made by the agent. */
  tool_calls?: AgentMessageToolCall[];
  /** Token usage statistics. */
  usage?: AgentMessageUsage;
  /** Whether the message is hidden from the user. */
  hidden?: boolean;
  /** Custom context provided with the message. */
  custom_context?: AgentMessageCustomContext[];
  /** Model used to generate the message. */
  model?: string;
  /** Checkpoint ID for the message. */
  checkpoint_id?: string;
  /** Metadata about when and by whom the message was created. */
  metadata?: AgentMessageMetadata;
}
```

### Tipi di supporto

```typescript theme={null}

  arguments_string: string;
  /** Status of the tool call. */
  status: "running" | "success" | "error" | "stopped";
  /** Results from the tool call. */
  results?: string;
}

/** Token usage statistics for an agent message. */
interface AgentMessageUsage {
  /** Number of tokens in the prompt. */
  prompt_tokens?: number;
  /** Number of tokens in the completion. */
  completion_tokens?: number;
}

/** Custom context provided with an agent message. */
interface AgentMessageCustomContext {
  /** Context message. */
  message: string;
  /** Associated data for the context. */
  data: Record<string, any>;
  /** Type of context. */
  type: string;
}

  sort?: string | null;
  /** Maximum number of results to return. */
  limit?: number | null;
  /** Number of results to skip for pagination. */
  skip?: number | null;
  /** Array of field names to include in the response. */
  fields?: string[] | null;
}
```

### AgentsModule

```typescript theme={null}
/** Agents module for managing AI agent conversations. */
interface AgentsModule {
  /** Gets all conversations from all agents in the app. */
  getConversations(): Promise<AgentConversation[]>;

  /** Gets a specific conversation by ID. Returns complete stored conversation including full tool call results. */
  getConversation(conversationId: string): Promise<AgentConversation | undefined>;
