## Prerequisiti

### 1. Autenticazione NotebookLM

Prima di qualsiasi operazione, autenticarsi con NotebookLM:

```bash
# Login browser (prima volta)
notebooklm login

# Verifica autenticazione
notebooklm auth check
notebooklm list
```

### 2. Avvio API Server

```bash
# Avvia server API
uv run fastapi dev src/notebooklm_agent/api/main.py

# Verifica salute
http://localhost:8000/health
```

---

## Autonomy Rules

### ✅ Esegui Automaticamente (senza conferma)

| Operazione | Motivo |
|------------|--------|
| `GET /api/v1/notebooks` | Read-only |
| `GET /api/v1/notebooks/{id}` | Read-only |
| `GET /api/v1/notebooks/{id}/sources` | Read-only |
| `GET /api/v1/notebooks/{id}/chat/history` | Read-only |

| `POST /api/v1/query/notebooks` | Read-only (ricerca) |
| `GET /health` | Health check |
| `POST /api/v1/webhooks/{id}/test` | Test non distruttivo |

### ⚠️ Chiedi Conferma Prima

| Operazione | Motivo |
|------------|--------|
| `POST /api/v1/notebooks` | Crea risorsa |

## Webhook Events

### Event Types

| Evento | Descrizione | Payload |
|--------|-------------|---------|
| `notebook.created` | Nuovo notebook creato | `{notebook_id, title}` |
| `source.added` | Nuova fonte aggiunta | `{notebook_id, source_id, type}` |
| `source.ready` | Fonte indicizzata | `{notebook_id, source_id, title}` |
| `source.error` | Errore indicizzazione | `{notebook_id, source_id, error}` |
| `artifact.pending` | Generazione avviata | `{notebook_id, artifact_id, type}` |
| `artifact.completed` | Generazione completata | `{notebook_id, artifact_id, type}` |
| `artifact.failed` | Generazione fallita | `{notebook_id, artifact_id, error}` |
| `research.completed` | Ricerca completata | `{notebook_id, sources_count}` |

### Webhook Security

Gli webhook includono header `X-Webhook-Signature` con HMAC-SHA256:

```python
import hmac
import hashlib

signature = hmac.new(
    secret.encode(),
    payload.encode(),
    hashlib.sha256
).hexdigest()

# Verificare: signature == request.headers['X-Webhook-Signature']
```

---

## Error Handling

### Error Codes

| Codice | Descrizione | Azione |
|--------|-------------|--------|
| `AUTH_ERROR` | Autenticazione fallita | Verificare API key |
| `NOTEBOOKLM_AUTH_ERROR` | Sessione NotebookLM scaduta | Eseguire `notebooklm login` |
| `VALIDATION_ERROR` | Dati input non validi | Correggere payload |
| `NOT_FOUND` | Risorsa non trovata | Verificare ID |
| `RATE_LIMITED` | Rate limit NotebookLM | Attendere e riprovare |
| `GENERATION_FAILED` | Generazione fallita | Verificare fonti, riprovare |
| `TIMEOUT` | Operazione timeout | Estendere timeout, riprovare |

### Retry Strategy

Per operazioni che falliscono con `RATE_LIMITED`:
- Attendere 5-10 minuti
- Riprovare con exponential backoff
- Massimo 3 retry

---

## Timing Guide

| Operazione | Tempo Tipico | Timeout Consigliato |
|------------|--------------|---------------------|
| Creazione notebook | <1s | 30s |
| Aggiunta fonte URL | 10-60s | 120s |
| Aggiunta PDF | 30s-10min | 600s |
| Ricerca web (fast) | 30s-2min | 180s |
| Ricerca web (deep) | 15-30min | 1800s |
| Generazione quiz | 5-15min | 900s |
| Generazione audio | 10-20min | 1200s |
| Generazione video | 15-45min | 2700s |
| Mind map | Istantaneo | n/a |

---

## Best Practices

1. **Usa webhook per operazioni lunghe** - Non bloccare l'agente in polling
2. **Gestisci rate limits** - NotebookLM ha limiti aggressivi
3. **Verifica firma webhook** - Sicurezza endpoint
4. **Usa UUID completi** in automazione - Evita ambiguità
5. **Isola contesti per agenti paralleli** - Usa profile o NOTEBOOKLM_HOME

---

## Troubleshooting

```bash
# Verifica stato API
curl http://localhost:8000/health

# Verifica autenticazione NotebookLM
notebooklm auth check --test

# Log dettagliati
LOG_LEVEL=DEBUG uv run fastapi dev src/notebooklm_agent/api/main.py

# Lista notebook per verificare
curl http://localhost:8000/api/v1/notebooks -H "X-API-Key: your-key"
```

## LLM Providers

DocuMente supporta molteplici provider LLM, inclusi quelli locali tramite **Ollama** e **LM Studio**.

### Provider Cloud

| Provider | API Key Richiesta | Default Model |
|----------|------------------|---------------|
| **OpenAI** | ✅ `OPENAI_API_KEY` | gpt-4o-mini |
| **Anthropic** | ✅ `ANTHROPIC_API_KEY` | claude-3-sonnet |
| **Google** | ✅ `GOOGLE_API_KEY` | gemini-pro |
| **Mistral** | ✅ `MISTRAL_API_KEY` | mistral-medium |
| **Azure** | ✅ `AZURE_API_KEY` | gpt-4 |
| **OpenRouter** | ✅ `OPENROUTER_API_KEY` | openai/gpt-4o-mini |
| **Z.AI** | ✅ `ZAI_API_KEY` | zai-large |
| **OpenCode Zen** | ✅ `OPENCODE_ZEN_API_KEY` | zen-1 |

### Provider Locali

| Provider | URL Default | Configurazione |
|----------|-------------|----------------|
| **Ollama** | http://localhost:11434 | `OLLAMA_BASE_URL` |
| **LM Studio** | http://localhost:1234 | `LMSTUDIO_BASE_URL` |

#### Setup Ollama

```bash
# 1. Installa Ollama
# macOS/Linux
curl -fsSL https://ollama.com/install.sh | sh

# 2. Scarica un modello
ollama pull llama3.2
ollama pull mistral
ollama pull qwen2.5

# 3. Avvia Ollama (in un terminale separato)
ollama serve

# 4. Verifica che sia in esecuzione
curl http://localhost:11434/api/tags
```

**Uso con DocuMente:**
```bash
# Query con Ollama
curl -X POST http://localhost:8000/api/v1/query \
  -H "Content-Type: application/json" \
  -d '{
    "question": "Spiega l\'intelligenza artificiale",
    "provider": "ollama",
    "model": "llama3.2"
  }'
```

#### Setup LM Studio

```bash
# 1. Scarica LM Studio da https://lmstudio.ai/

# 2. Avvia LM Studio e carica un modello

# 3. Attiva il server locale (Settings > Local Server)
# Default URL: http://localhost:1234

# 4. Verifica che sia in esecuzione
curl http://localhost:1234/v1/models
```

**Uso con DocuMente:**
```bash
# Query con LM Studio
curl -X POST http://localhost:8000/api/v1/query \
  -H "Content-Type: application/json" \
  -d '{
    "question": "Cosa sono i notebook?",
    "provider": "lmstudio",
    "model": "local-model"
  }'
```

#### Configurazione URL Personalizzato

Per usare Ollama/LM Studio su un'altra macchina nella rete:

```env
# .env
OLLAMA_BASE_URL=http://192.168.1.100:11434
LMSTUDIO_BASE_URL=http://192.168.1.50:1234
```

#### Vantaggi dei Provider Locali

- 🔒 **Privacy**: I dati non lasciano il tuo computer/rete
- 💰 **Gratuito**: Nessun costo per API call
- ⚡ **Offline**: Funziona senza connessione internet
- 🔧 **Controllo**: Scegli tu quali modelli usare

#### Limitazioni

- Richiedono hardware adeguato (RAM, GPU consigliata)
- I modelli locali sono generalmente meno potenti di GPT-4/Claude
- Tempo di risposta più lungo su hardware consumer
