Durable State Patterns

Build agents that remember state across failures, restarts, and sessions.

Why Durable State?

Without durability:

• Long-running agents lose progress on crash
• Users can't resume conversations after timeout
• No audit trail of agent decisions
• Expensive recomputation on every restart

With durability:

• Resume from any checkpoint
• Survive infrastructure failures
• Debug by replaying history
• Share state across instances
