# Rollback Strategies

> Techniques for recovering from agent drift.

Rollback is not just for errors; it's a strategic tool for agent autonomy.

## 1. Automated Guardrail Rollback

Integrate a "Guardrail" model (like Llama-Guard or a regex filter). If the output is unsafe, automatically roll back the session state and prompt with a "Correction" instead of showing the failure to the user.

## 2. "Rewind" UI for Users

Give users a "Undo" button. When clicked, call `sb.sessions.rollback(count=1)`. This is incredibly powerful for creative agents (co-writing, coding) where the user wants to try a different branch.

## 3. Tool-Failure Recovery

If a tool call returns a 404 or 500, rollback the agent's state to *before* it thought about calling that tool. This prevents the agent from getting stuck trying to "fix" a broken external dependency.

***

**Founder Insight**: Rollbacks reduce your support burden. An agent that can "self-correct" by rewinding time is an agent that stays in production longer without human intervention.
