Durable Execution
What does durable execution guarantee for long-running AI agents?
Durable execution guarantees that your AI agent's workflow state is preserved across crashes, restarts, and failures, so it resumes from the last checkpoint. Catalyst persists the execution history of deterministic steps, ensuring orchestration continues without manual recovery. However, it does not guarantee exactly-once execution of external side effects—those require idempotency or reconciliation logic. This lets you build resilient agents that survive infrastructure failures without losing progress.

Why do production AI agents need durable workflows?
Production AI agents need durable workflows because real agent tasks rarely finish in a single clean request.

Is checkpointing enough for production AI agents?
Checkpointing helps, but it is usually not enough by itself for production AI agents. It explains the production reliability impact for AI agent workflows.
