Why AI Agents Need Platform Durability, Not Developer Checkpoints

Current AI agent frameworks treat crash recovery as a developer responsibility, forcing engineers to write substantial boilerplate code for state persistence—a hidden cost called the 'checkpoint tax.' The article argues that durability should be a platform-level concern by default, much like how HTTP services such as Stripe handle idempotency, ensuring agents remain stateless while infrastructure guarantees operation completion through crashes and restarts.
