# Agent Hallucination Recovery

> How to detect a drift and revert to a sane state.

AI agents don't always fail loudly. Sometimes they "drift"—entering a state where they hallucinate facts or enter infinite loops. This demo shows how to use StateBase to recover instantly.

## The Scenario

A customer support agent is helping a user reset their password. The agent accidentally tries to update a `null` field, causing the LLM to get confused and start repeating "I'm sorry, I can't do that" in a loop.

## 1. Detection

In your application logic, you detect that the last 3 outputs have been nearly identical.

## 2. The Rollback

Instead of killing the session, you simply roll the session state back to the turn before the error occurred.

```python theme={null}
# Detect drift...
if is_hallucinating(last_turns):
    # Rollback to 1 turn ago
    sb.sessions.rollback(session_id=session.id, turn_count=1)
    
    # Retry with a 'correction' prompt
    retry_prompt = "You encountered an error. Please try a different approach."
```

## Why this matters

* **Save Revenue**: You don't lose the user's progress. They don't have to start the 10-minute onboarding over again.
* **Traceability**: In the Dashboard, you'll see a "Rollback Event," allowing your developers to analyze the exact turn that caused the drift.
* **User Experience**: The user sees a slight delay followed by a successful answer, rather than a "System Error" message.
